Chapter 39: Potential

Year 19: Day 63: You Win Some, You Lose Some Part 2

(Ark's City)

After telling my experience in the Harry Potter universe for over 99 years. I include meeting one person, a female hero, from the [Hero Faction] and explained what I learned from the memories I gained from that female hero.

I didn't bother to hide from my Daughters about how I literally killed a hero, causing them to hide the fact they are scared for their parallel loved ones if they face me, along with the rest of the family.

After all, in this entire family; only the kids are most likely the good guys without too much blood on their hands while the rest of us can't even bother to remember. This is where we no longer consider as human, not that most of us are human, to begin with.

I share a look with my wives, where they notice how I look at the kids with a small frown, letting my wives know that we will have lots of work on her our hands.

Unless we're willing to distance ourselves from our own children when they won't change at all or risk them experiencing war itself. Something no parents wish for their kids to experience, this included the entire Mercer family. At this Mercer family of mine and not the Mercer Clan of cultivators.

Of course, the wives and I had talked before how we would have allowed our kids to live their own lives in a parallel dimension of their previous home universe, but after learning about the [Hero Faction], [Neutral Faction], and the [Evil Faction].

That idea disappeared instantly. Since those three factions are willing to use hostages to get what they want. Something to be proven true when I look through the female hero's memory and shared it with the wives after breakfast, where Repellista took care of the kids.

Repellista didn't have to be in person to join our group conversation, thanks to her [Lighthouse] among us to allow her to listen.

"So almost 100 years, huh?" Raven looked at me wondering if the training I went was worth it. As most males, husband or just good marriage with a great sėx life could handle without sėx for almost a hundred years if possible while keeping their youth.

"Yup." I replied in a dull tone, something that all my wives caught on at how my tone is a bit different now. Since it isn't the same dull, bored tone, but something that is hidden behind that dull tone.

All my wives glance at each other, then look back at me.

"Something wrong?" I ask with the same dull tone, as my left eye kept track of each of my wives' movement. Something that became a habit now at this point, where I would make sure to be ready for anything at the last second.

I didn't show anything on my face or any body reaction in front of my wives before I send a [Volition Sword Intent: Sword Gaze] at all my wives, causing them to stiff, cold sweat started to cover their foreheads as they look at me with shock and fear.

[Sword Gaze] is something I remember in some wuxia novels where a powerful [Sword Cultivator] were able to kill their target with just a gaze alone. So, I recreated it with the help of the [Volition Sword Intent] and based on the feeling of a predator gazing at its prey.

But, instead with the [Sword Gaze] that make one feel like they have a sword pointing directly at their neck or somewhere on their body and could imagine their death by sword; however, that would just be an illusion while my [Sword Gaze] can literally allow me to kill my target(s) with just a gaze alone by sending [Sword Qi] the moment my eyes land on the target and I will it.

Well, for those beings that weaker than me. Stronger beings or close to my strength could somewhat deal with it or at best, be immune to it.

So right now, my wives are literally feeling my [Volition Sword Intent] that have been tempered over 99 years through bloodshed and fighting with my life on the line almost all the time. Pretty short compared to those people in wuxia novels.

"I do wonder why you wanted to try to attack me." I said to my wives, causing them to shake a little before I blink my left eye and the [Sword Gaze] deactivated. A bit of a waste of [Sword Qi] since even if I don't kill the target, it still uses some [Sword Qi] to power the [Sword Gaze].

"W-Well." Esdeath cough in her hand, embarrassed that she of all people would stutter, but the way her husband looks at her made her feel like everything she hid is revealed before his eye. Also, this made her feel a bit excited in a good way, causing her to lower head a little and her face slowly turning pink.

The others are shocked that Esdeath would stutter as well, in fact, some even believed that she never stutter in her entire life and isn't able to stutter in the first place.

"Well, we just wanted to see how much you improved, but it looks like we may have underestimated you." Esdeath said to me, as she looking at me with hunger in her eyes and this alone made the suppressed urge to take Esdeath there and then almost made me lose control, but I ruthlessly crush that urge. For now.

"And by that, she meant we seriously underestimated you by a lot." Alice said with a dumbfounded look on her face, no longer afraid, same with the others and nodding in agreement.

"Let's just say, even though the people there are weaker than me. That doesn't mean my life wasn't at the edge of death each day." I said dully, as I started explaining further on how I trained myself.

"Okay, enough of this depressing mood. Tell us, did you manage to get the [Deathly Hallows]?" Yuri asks me, curiosity in her voice, with the rest being curious as well.

"Yup." I said dryly, wonder if all my wives is a Harry Potter fan, then look at Esdeath, only has that hunger of ŀust in her eyes, so maybe not all.

"Did you become the [Master of Death]?" Alice asks me, eager to find out if what she read in the Harry Potter series about how collecting all the [Deathly Hallows] would make one the [Master of Death].

"Nope. Look like the whole [Master of Death] thing is false or at least in the dimension, I was sent in. However, the [Deathly Hallows] is real, but useless to me, but I collected it nevertheless." I take out the [Deathly Hallows] for my wives to see.

"The [Elder Wand] useless to all of us unless one of us dėsɨrė to use [Wand Magic]. Then, the [Resurrection Stone] or at least this one isn't even that useful. Since it only allows the user to summon the spirit of the user's loved ones from beyond the afterlife and only loved ones, no one else but them, along with 1% each use would lead the user's mind to crumble with only left with the dėsɨrė to kill themselves to reunite with their loved ones. So yeah, it's a double-edged item." I explained the first two [Deathly Hallows] how they not really useful in my hands or the rest of us.

"As for the [Cloak of Invisibility]. Useless as well, because even I could detect whoever under it with ease. I don't even need to be death itself to find the wearer of this cloak." I said with absolute with disdain towards the [Deathly Hallows], but took them anyway, since my family could use them or at least one of my kids, if not them, then I could just figure something out to use them in some way.

"Wow." Yuri said dryly, "Talk about bringing down some of my fantasies like nothing."

I smirk at this, "Oh, they are powerful. Only in some universes and in the Harry Potter universe, of course, but honestly, I may have gotten a weaker version of the [Deathly Hallows] among the many ones shatter in the Harry Potter universe."

"Well, I'm good. None of the [Deathly Hallows] are worth using in my hands either." Esdeath instantly rejected the chance of obtaining one or all three [Deathly Hallows]. For one: she not going into [Wand Magic]. Two: her loved ones are alive and well. Three: why should she hide at all? She will allow the challenge to come to her!

"I'll give it a pass. After finding out the whole [Master of Death] isn't true and with the [Deathly Hallows] being..." Yuri didn't even finished and sighed in disappointment.

"Well, we could see if our husband could turn the [Deathly Hallows] into a weapon that's useful." Raven said to Yuri, who thought about it.

"Nah, better to rely on my own [Skills] and plus I have a weapon that's more useful than those [Deathly Hallows]." Yuri knows that the [Life Stealer: Korosu] is a powerful Teigu and she still working on creating other trump cards for it.

Ryun didn't even put these [Deathly Hallows] in her eyes after listening to her god talking about how weak they are and only powerful in certain universes. So, like her god, she finds them useless and not worth the effort to think of a way to turn them into something better.

"Hmm." Alice rubs her chin, picking up the [Elder Wand], but felt nothing at all besides it feels like just a fancy looking stick to her. "Well, that answered my question. No reaction at all." Alice tosses the [Elder Wand] to the ground and no interested in it.

"Don't bother looking at me. I already have my go-to weapon. I don't need any stick to do the job for me." Raven didn't even put the [Elder Wand] in her eyes. After all, she got [Sky Dragon Slayer Magic] that better in her opinion.

"Anyway, I decided maybe we do some training. I will, of course, hold back in our spar. Don't worry, I'm not even going to use any [Void Weapons]." I said to my wives, as they had a worried look on their faces when they heard me asking for a spar now.

Sure, all the wives had fought with their husband, but that was before their husband went through almost a hundred years of training. Who knows what he came up with during those times.

"Oh, and don't reject this. We need to continue getting stronger while we have the chance." I gently smile at my wives.

Unknown to everyone. This new side of the wives' husband caused mixed new emotions to appear and in a good way. Really in a good way, but currently, all wives are kind of scared, with only Esdeath and Yuri didn't seem that bothered about this and is excited before remembering they didn't have the same time to increase their strength compared to their husband, causing dread to fill them up slowly.

A few minutes later*

(Ark's City: Training Building: Wonderland)

I crack my neck, then stare at my wives, causing them to feel uneasy. Because all the wives versus their husband. Something that's rarely done.

'Let's see. I will use [Rejection], [Moon Light Sword Style], [Ninjutsu], [Right Arm of Thievery], and [Mystic Eye of Death Perception].' I start using [Chain Combo Magic] to link all these [Skills] together for me to use all of them smoother and easier. Along with giving me the ability to use all these [Skills] without having to deal with the lag of switching to it.

Something I learned the hard way that even if it looks like I'm instantly switching one [Skill] to another, but in reality. I found out that each time I switched to another [Skill] while in the middle of using it. There is a small lag in between, something no one would able to use even if they found out.

But, that doesn't mean there are misfortune moments where the enemy side had a lucky moment to hit me during that period. Even if it's just under a second. After all, there are powerful beings in the multiverse could attack thousands of ways within a second or under. Not to mention those that could attack instantly, as in a true instant attack with the effect of space-time to make it an instant attack.

I could see the worry from my wives' body language. Since they could easily tell I have activated [Mystic Eye of Death Perception]. Furthermore, the effects belong to this [Skill] have been enhanced by [Chain Combo Magic] that increase all linked [Skills] by the amount of [Skills] are being linked.

Currently being five [Skills] that are linked under the effect of [Chain Combo Magic], with [Chain Combo Magic] itself not being counted, increasing all five [Skills] by five more than its maximum level.

In a way, the [Chain Combo Magic] itself is a [Broken Skill] as well. Since the [Chain Combo Magic] bypass the linked [Skills]' max level effect and increase it further still as the number of [Skills] that are linked.

Not to mention, the [Chain Combo Magic] has an hidden effect that actually causes the linked [Skills] to be able to do things that shouldn't be possible.

For example, I just use [Right Arm of Thiever] to literally 'steal' the 'distance' between the wives and me. This fall under [Space Manipulation] in a way.

"WHAT THE HELL?!" Raven shouted as she swings her sword right at me, but that attack fails instant.

As I use [Rejection] on Raven's momentum, causing her to stop on the spot like she is frozen in place. Something that scared Raven instantly as she no longer can move her body.

I glanced over to Esdeath already following an ice wall between us, but that wasn't enough as I use [Mystic Eye of Death Perception] to find the [Lines of Death] on the ice wall and use [Ninjutsu] to create an illusion sword before using [Rejection] on the concept of illusion, making the illusion sword real for this moment.

Then, using [Moon Light Sword Style: Slash] and split the ice wall into multiple pieces with a single slash. I found Esdeath not hiding behind the ice wall and must have made an escape to create distance between us, so she could regather her thoughts and plan things out. Something that would fail her anyway, but I allowed her to keep her distance for now.

Dismissing the sword in my hand and use [Rejection: Rejected Impact], to block Yuri's high kick to the right side of my head. Making it so that the moment Yuri's left foot moving close to my head at high speed.

The damage she could have caused is null and void as the concept of impact is rejected, making it look like Yuri just placed her foot on the side of my head. Even Yuri won't feel the 'impact' at all.

Grabbing the surprised Yuri's left foot and use [Right Arm of Thievery] to steal Yuri's raw strength, causing Yuri to collapse to the ground due to not having the strength to stand on her own two feet.

I take a step back when Alice tried to claw my ċhėst and use [Ninjutsu: Slow Down], tricking Alice's sense of time as if the time is literally slowing down.

Then, using [Moon Light Sword Style: Piercing Pulse], a [Swordless Technique] performed by using the palm to send an [Energy Wave] or shockwave to damage enemies. It can knock an opponent to a considerable distance, sending them flying into the air.

With Alice's case, she was blasted away without understanding how she got hit and soar the sky. As Alice disappears a couple of meters away, and also, I held myself back with this [Technique]. Since I did at one point cause a target to explode instead.

Ryun tried to attack me the moment I took my eye off her when a flying knife came straight for the back of my neck. Something I already notice instantly.

Too bad for Ryun. I had countless of things flying at me during my time in the Harry Potter universe. Say what you want, but when wizards and witches get motivated, then they get creative. Plus, some of the non-magical humans from the higher-ups even sent missiles at me before.

Using [Rejection: Rejected Space] and use [Right Arm of Thievery] to snatch the flying knife out of the air and not even having to turn around to look at it or grab it. As the knife appears in my right hand instantly.

"Nice try." I said to Ryun, as I throw it straight back at her, twice as the original speed, but that didn't do anything since Ryun had her [Bone Loops] out to protect her, this including her own attacks.

"It isn't over yet!" I heard Esdeath's shout on my left, then a blast of cold air hit me. Ice started to form over my body.

DING!*

You gain the debuff: Frost Burn: -1000 HP per second, duration 1 minute.

DING!

Debuff: Frost Burn is removed under the effect of the [Skill: Rejection].

Not even after a whole second passed and the ice disappeared instantly before it spread throughout my entire body.

My ears twitch as I picked up a soft singing, then narrowing my eye and instantly figure out what's going on.

I move my right arm, but found Esdeath appearing on my right and have already grabbed my right arm the moment I was distracted for a split second.

DING!*

The [Right Arm of Thievery] has entered a cooldown phase for an unknown time period.

Something I'm impressed that even after close to a hundred years. Esdeath could match me in speed before I dismiss that thought because I instantly realize what Esdeath had done.

The cold air blast has been just a faint for her to follow up with her next move. Esdeath using her first trump card: [Mahapadma]. Literally freezing space and time, with only Esdeath herself could move.

I could do the same with [Sword Qi], but since I don't have [Ice Devil Slayer Magic] anymore. This [Mahapadma] can affect me more compared to before. Not to mention my [Rejection] won't stop this if I wasn't prepared for it.

So, yes, I'm very impressed with Esdeath's quick plan and I can't even use [Right Arm of Thievery] due to Esdeath using her subtype [Mahapadma] to put the [Right Arm of Thievery] in an endless cooldown, making it impossible for me to use the [Right Arm of Thievery].

Of course, I could still use my right arm as only the [Skill: Right Arm of Thievery] was target only and not the arm itself.

I smirk that Esdeath figures a way to use her Teigu to literally affect a Gamer's [Skills] somehow.

But, that didn't work for long as I use [Rejection] to counter this. Something Esdeath has figured out already as she strikes with a free hand in the form of a spearhand, with the fingertips covered in sharp pointy ice, aiming for my throat the very moment I use [Rejection] to counter Esdeath's preventing me from using [Right Arm of Thievery].

I grin at Esdeath, who match it with her own as I use my left hand to grab the wrist of the hand Esdeath attacked.

"Got you." Esdeath said to me in a soft voice, but she saw the look in my left eye that I already knew she was a distraction this whole time.

"For we are free, we are not bound to the laws of reality~!" I heard Alice sing out the last word and I found all the [Rejection] I used to reverse. Even the 'distance' of space I 'steal' is returned.

Even Esdeath disappeared from my sight as she appeared next to Raven and Yuri, with Ryun and Alice appearing with Esdeath.

"Oh. I see the [Fonic Hymns]. I honestly forgot I gave you it." I spoke out my thought in a dull tone, forgetting with the right user, then they can make any [Skill] be it weak or just plain common, to become beyond powerful than it should; well, at least for genius talented people or main character with plot armor.

"You got that right love. Took me some time to find the right song to use, but thanks to the previous universe. I have all the songs I need to use and even have to change a few words if needed and I get the effect I wanted." Alice said with prideful voice, no one could deny this as the [Fonic Hymns] use words of a song as a chant for a [Song Effect Magic]. Literally making any words of the song like an actual [Spell].

"Got anything else?" The moment I said this, I use [Mystic Eye of Death Perception] to 'look' at the [Points of Death] and in my messed up mind. I deemed 'death' related to the end and as the end of a [Skill/Technique/Spell/etc].

Finding what I wanted. I created an illusion of a sword next to the [Point of Death] nearest me while using [Rejection] to make it real and at the same time using [Sword Qi] to manipulate the sword from a distance, making it a flying sword temporary as I 'stab' the [Point of Death]. Ending the effect of this [Song Effect Magic].

All happened near instantly before any of my wives realize what just happen.

The surrounding became surroundings as my wives tried to comprehend what just happen.

"Fuck it. I surrender." Alice is the first one to snap out of it. "That's just plain cheating in a whole new level." Alice knew right away that her husband somehow makes her [Song Effect Magic] end instantly. Not cancel, but make the effect's duration end faster than it should.

"Yeah, I rather not continue this sparring match. Like seriously, I was out of the fight not even a minute has passed. Hell, maybe not even pass 2 seconds if I haven't guessed wrong. Talk about scary not being able to move at all." Raven agreed with Alice and because she was the first to be taken out of the fight, but at least she made a move in her opinion than be defeated without being able to do a single thing.

I tilt my head and blankly stare at my wives, causing some to be nervous for some reasons.

"You do realize what I have done could be done by others as well, right? Not to mention the [Rejection] may be a [Broken Skill], but others have similar effects and can do the same. It depends on the users on how to use these [Broken Skills]. I mean, look at Alice, her [Fonic Hymns] has the potential to become or already a [Broken Skill] after she just undo all the effect of my [Rejection]. The only limitation on the [Fonic Hymns] is the song itself. It doesn't even have to be in the language she speaks it. As long she understands it and her will. The song will lead to the [Song Effect Magic] Alice dėsɨrė." I started explaining how one [Broken Skill] or a potential one after solving the downside of them. Could lead to counter other [Broken Skills] after figuring out the weakness to it.

I explained how even if they are called [Broken Skills], in my words, that is, they are still bound to have a weakness. You just had to have the right [Skills] and your wit to defeat these [Broken Skill].

"In fact, Esdeath herself is already making multiple [Broken Techniques], similar to a [Broken Skill], but under the power of a single [Skill]. Making that [Skill] the same as the [Fonic Hymns]. A potential [Broken Skill]. She has already figured a way to literally affect the Gamer's ability, even if she connected with it. But, if she figures a way to do the same to other Gamers. Then, Esdeath would be able to prevent a powerful Gamer from using their powerful [Skills]." I point the fact that Esdeath, this version out of the other counterparts, can kill countless Gamers if they don't have the right [Skills] to face her, and even then, she could technically place all the [Skills] other Gamers would use into an unknown period time of cooldown, allowing Esdeath to kill the Gamers after becoming defenseless without their [Skills] to protect themselves, maybe.

"I see." Raven nods her head, understanding that depending on the [Skill]. Who knows if that [Skill] has the potential become a [Broken Skill] that is also another term for an overpowered [Skill] that break the balance of power in certain universes.

Alice looked down in deep thoughts, to think she already has a [Skill] that has the potential to become a [Broken Skill]. No, she knew right away the original [Fonic Hymns] wouldn't have the potential to be a true [Broken Skill] outside of its own universe. What she got was the [Fonic Hymns] that came with the potential, and if she had to guess, her husband's Gamer's ability removed certain limitations on it. Giving the [Skill] itself the potential than what it had to begin with.

"Is it possible?" Alice asks herself, causing everyone to look at her, "Maybe some of the [Skills] we gained from our husband have their restrictions remove. No, not a restriction in power, but the restriction to go beyond without an end. Making it more power than it already is."

Upon hearing this. All the wives started thinking and comparing all the [Skills] they gained from their husband with the original version from where they came from. Then remember that the [Skills] they gained don't come with a level and just knowledge. A foundation of knowledge for them to study and have the ability to use those knowledges, along with the future new knowledge they come up with.

"Now, that I think about it. Alice is right." Yuri said in shock, not realizing how much powerful she could become just from some [Skills] she gained from her husband.

"Wait! Is this why you got us to fight you right now?" Raven asks me, looking at me with eyes widen to discover that I may have planned this whole time.

"Is this true?" Alice asks me if this was true, as she looks at me in awe if this was true.

Ryun already looking at me like she knew right away that I plan this out the moment I returned and ready to put it into action.

"You just wanted us to continue training and this whole [Skills] with the potential to become [Broken Skills] just a bonus, isn't it?" Esdeath asks me with a deadpan on her face.

This caused the rest of the wives to look at Esdeath in confusion before remembering a few events that proved what Esdeath said is true. This made them feel like they were overthinking things about the whole situation once more. As they are still not used to the whole Gamer's ability and the multiverse after all these years together.

I didn't say anything and smile, which is an answer itself, causing Esdeath to sigh.

"Well, look like we have to increase our training girls." Esdeath said to her fellow sisters, all of them have eyes of determination to go beyond what training they put themselves already and wanted to go beyond as well.

With the help of the [Skill: Wonderland]. No one has to worry about becoming a cripple or death.

"So when are we training the kids?" Ryun asks everyone, wanting no more to help bring her little gift to become strong like her Father.

"Honestly? Today, if possible, before we enter the Harry Potter universe." I answered Ryun's question, causing some of the wives to wonder if this was right to start their kids now or not.

"Before anyone thinks about if they are put in danger our stunt their growth. Don't forget that they are not human, to begin with." Esdeath said to everyone, causing some to remember that this is true.

Not to mention Kaori, Daughter of Esdeath contain the inborn ability of the Teigu: [Demon Extract]. Giving her the ability and potential at the same level as Esdeath in using her ice ability.

Chifuyu having Yuri's inborn powerful body, giving her stronger body strength compared to her two sisters.

Erza has better senses than in body compared to the other, making Erza having a bit harder time to catch up with her sisters in body training, but that doesn't make her weak at all. In fact, she is stronger than the average human in the same age group as her.

"Hm. I guess I got too used to thinking about the logic of my world." Raven mused about this simple fact.

"Also, they are [Reincarnators] as well and including their inborn abilities they gained from us. They are already having a head start, like those main characters that reincarnated into another world." Yuri points this out as well.

"So, maybe today then?" Alice asks with curiosity, wanting no more to help the family's kids become strong to defend themselves from anything harmful to them. They may not be her own kids and blood, but that, doesn't she won't treat them like her own.
