Within the Wolf Valley, a great battle was taking place, as a single human being chose to go against multiple wolves all by themself.

It was a woman dressed in black. A tight fit gear that held her figure perfectly well, illustrating her top class athletic figure. One at the peak of peak human physiology.

She dashed through the forest at insane speed, crossing multiple meters in just a single step.

She was so fast, she felt like a blur of dark light as she traversed hundreds of meters with every step, and leaving behind a pack of wild angry wolves numbering in the thousands.

And amongst these wolves, some were capable of traveling at sound speed, and tailed behind her. They had speed-type mutations.

Yet they could still not catch up to her. 'My speed has been decreasing lately. It's as if I am being suppressed by something. Like I am almost ten times slower than I usually am.' The woman thought as she ran.

She had deliberately slowed down her speed so that the wolves that could travel at sound speed, could slowly catch up to her.

And once they were about to catch up, she slowly increased her speed, and maneuvered through the forest at insane speeds, dodging obstacles and trees like a professional acrobatic.

The wolves always followed behind her, not willing to let go. The anger and killing intent was apparent within their eyes.

"..."

Esther ignored all that though, and kept running and running. She had nothing in her mind either than to run, and to run, she did.

Boom!!

She kicked off and shattered the sound barrier with her speed. The wolves chasing her also kicked off at full speed and each shattered the sound barrier after her.

They were like blurs of light, of varying colors. The wolves chasing her were Advanced Wolves, or rather, the current Beta Wolves of the current Wolf Clan.

They were fifteen of them, and this was not even 1% of the Beta Wolves. But Esther was not worried, she was not working alone right now.

"..."

She ran, and swiftly did an acrobatic jump, mixed with a flip. In her mid air posture, she threw sharp needles that each shattered the sound barrier and struck three Beta Wolves.

Two were killed immediately, and one slowed down, but death was for sure. The needle had struck straight on the neck.

But the Grays were never ones to play fair. They were cunning devils. One of them was Esther, the number one assassin.

Esther curled mid air, then landed on a tree, and kicked off at extreme speed once again, taking off like bullet let loose.

The wolves chased after her, but two unfortunate wolves were suddenly diced into bloody mist, flesh and bones everywhere.

...!!!

The other remaining wolves did not stop but carefully maneuvered the area, and as they did so, they realized that the path to chase after Esther was riddled with spider-web-like tight strings.

They were frightened, but not overwhelmed. The death of five of their brothers angered them more, and they chased after the daring woman with hatred.

Yet their every step was full of caution within. Unfortunately, caution proved to be unnecessary against a Gray. Especially this small family of three.

Esther slowed down her speed ever so slowly, making it seem as if they were catching up to her by themselves.

In their angered state, it gave them the impression that their anger and hatred made them run faster than they actually could. It was high leveled mind play.

They believed they went over their limits.

"..."

Esther glanced at them from behind as they got closer and closer to her. Then up ahead, the trees were getting narrower and narrower, a sign of an open space up ahead.

But she was unphased and kept running. The wolves that believed that Esther was fast only because of the trees, were joyfully at that discovery.

They pushed on ahead, and waited for the moment to rip apart their prey once she gave them even the smallest chance out there.

And once they reached the periphery of the forest, where no trees could be seen, Esther jumped up and disregarded the wolves.

The wolves looked up while chasing, and forgot to look ahead. And up ahead, was another perfect trap Esther laid for her predators. One that was full-proofed.

'Checkmate.' She thought, mid air, looking down on the wolves, as they also looked up at her. Not aware of their coming death.

And moments later, once out of the forest, they stepped over a patch of grass that was lighter than the sorounding patch in shade, causing all ten wolves to sink down into the earth.

"Awoo!!"

"Aw..."

"Awwooo!!"

Normally, a single person would not he heavy enough to sink the trap, nor notice that the grass was out of place. Of course, unless they were innately observant in nature.

Not even ten people could be heavy enough to cause it to sink down. But one must remember, a single Advanced Leveled Wolf was heavier and larger than a normal human.

It was around eleven meters long, and five meters tall, and weighed over six hundred kilograms. Wolves here were originally twice as large as earth wolves before mutation.

Ten of them accumulated to approximately over six tons, which was more than enough to completely sink the pit trap filled with well forged sharp weapons and pikes.

Each weapon planted to face up, ready to piece anything falling within with extreme ruthlessness. It was like falling into the maws of a powerful beast.

"..."

Meanwhile, Esther used [Wind Control] to twirl wind around her body, slowing down her descent. Then, she maneuvered herself carefully and landed on the edge of the pitfall trap.

Looking down, she saw all ten wolves pieced and ruthlessly killed. They evolved in terms of speed, and not in terms of defense.

With their speed, and free fall that was so deep, they were destined to be pieced to death without any hesitation from the weapons.

This was just... ruthless.

Esther watched them for a few more seconds, then moved back towards the thousands of Adept Leveled (Tier 2) and Apprentice Leveled (Tier 3) Wolves that were left behind.

She began her hunt like a true assassin, killing them one by one, like a shadow in the dark, like a ghost in hell, and like a devil given the get-go at the end of times.

Her every movement was calculated, and ruthless. And she was faster than them, hence they could barely do anything against this great messenger of death.

The number one assassin of humankind.

She was just monstrous.

An hour or so later, she stopped her killing spree, and watched as the forest was laid down with wolf corpses and blood everywhere.

It was terrifying.

Moments later, she was done killing.

And the sorounding pungent smell of blood was potent. But Esther grew in bloodshed, and was not phased. From beginning to end, her expression was null and empty.

It was very much unlike her motherly x wifely expression she shows her family.

[ TING!!! ]

Esther went through the notifications, then decided not to Level up once again. She was planning on going all the way to becoming an Advanced Shadow Speedster.

For her Hidden Class, it was a little over 21 000 units of Life Essence. And she could collect enough of that after a few more eliminations like these ones.

"I wonder how my hubby is doing." She thought out loud, and let curiosity get the best of her. She vanished at fast speed, and went towards David's direction.

Along the way, she killed a few more small parties of wolves, and leveled herself all the way to the peak of the Apprentice Rank, level 10, then paused.

[ TING!! ]

[ You have leveled up... You have leveled up... You have leveled up... You have leveled up ]

[ Due to your HIDDEN CLASS, you have spent 3,360 units of Life Essence to Level up all the way to Level 10. You have obtained more benefits from level ups ]

[ Your AGI, END and AFF have increased by 12,0 points each ]

"Oh." Esther knew that Hidden Classes were amazing, but nobody told her they were THIS amazing. Well, she read the definition and knew it herself.

But experiencing the effects themselves was better than just reading them. She was far faster than she used to be, but most importantly...

[ You have enough Mana to use Unique Abilities with reserve. The minimum cost of the lowest Unique Ability transcends fifty million units of Mana. Work with caution ]
