Ye Yang first had a good sleep. He was full of energy and washed, so that his spirit was at its peak and his state of mind was good.

This is the only way to avoid Ji Yan and find a place to improve her level alone.

After rising to lv17, various powerful skills have begun to appear. Ye Yang is worried that he will miss some good abilities, so he is ready to improve his level with "high-speed thinking".

"Upgrade!!"

The data displayed by Ye Yang's current system changes rapidly, a large amount of upgrade energy is lost, and Ye Yang's level has also risen from lv18 to lv19.

Three points of freedom attribute, all added to intelligence, the spirit limit is increased.

"Skills, skills, what should I choose?"

Now there are quite a lot of skills to choose. There are many abilities that make Ye Yang very excited. However, each one is very good, but you can only choose one. Try to choose the most useful ability for yourself at present.

"I have offensive skills. There are many life-saving skills. A variety of auxiliary skills are also good, but I still lack an active defense skill."

Ye Yang has defensive skills... But he is passive and falls into the category of "talent".

It's the "copper skin and iron bone". The bullet will not be affected as long as it's not a special bullet or hit the fatal part.

Of course, skill points can also open various physical talents, intellectual talents, or agile talents.

For example, among the physical talents, there is a high-speed self-healing ability, and there is a "super physical strength" talent that needs to absorb the energy crystal core of life attributes.

Super strong physical strength. You won't be tired after running for several days and nights. Although this is powerful, even without this talent, Ye Yang will never breathe even if he runs for most of the day, as long as he doesn't continue to sprint.

But with super strength, you can sprint every few seconds.

What's more... Ye Yang can walk and sleep at the same time. Even if you do some mechanically repeated actions without thinking, you can recover your physical strength and mental strength... In short, you can recover slowly without consuming your mental strength.

This ability is really amazing.

In addition, you can use the ability of "secondary undead" once a day. In other words, as long as it is not killed by the second, even if the injury is serious, it can quickly lock the fatal wound of the body and make the blood no longer penetrate. Even, some body fluids can be bypassed, or life energy can be used to temporarily replace the role of some organs.

For example, if a normal person's internal organs are removed, he will die, but as long as Ye Yang does not directly remove the heart and brain, no matter where other parts are damaged, he can remain immortal for a period of time.

"Very powerful, but unfortunately... It's of no use to me now."

There is also the talent of agility, which makes the response more rapid. Unfortunately, on a whim, this kind of agility talent has little effect. Of course, the main thing is not willing to waste skill points here.

"This time, first add a defense skill, and then a mobile skill."

Ye Yang's life-saving ability is very strong now, but if he is in a very narrow place where he can't avoid the enemy and can't carry out space transmission, his defense skills are important.

It can be said that we don't need the ability to be prepared now.

The same is true for skills such as increasing movement speed.

"It's useless at ordinary times. It's quite wasteful to add skills here. But in special cases, these skills play a strong role. Now I have strong abilities in all aspects. At this time, I shouldn't strengthen and highlight one aspect, but try to make up for my weaknesses in all aspects."

Ye Yang's weaknesses include no strong defense skills and no strong acceleration skills. Even if the mind can speed up and the body's movement speed can't be improved, it's useless.

These weaknesses have no impact on Ye Yang now. But the short board is the short board. If we don't make up for it, we will have something sooner or later.

"So..."

Ye Yang looked at various skills.

"White bone armor, white bone flying shield, white bone flying helmet... All these need materials. Like the bone spear, you must carry bones. Well, pass them all.

"Stone skin technique... Can block attacks with a certain intensity... It's useless."

Ye Yang has seen similar skills in some games, such as iron skin and stone skin, which can resist many attacks. However, in reality, this skill has been weakened a lot.

"I don't have the ability to defend against magic weapons and weapon attacks... In fact, what I want most is skills such as space barrier..."

Ye Yang's half plane space can release the power of space to protect himself. However, it is too short, unsustainable, unstable and difficult to control. It must be distracted and controlled at any time, so it can't rely on half plane space alone. Various bulletproof vests affect movement.

"Eh? This skill..."

Ye Yang held the energy crystal nucleus in his hand.

"At the cost of consuming a dark system energy crystal core, and consuming part of the space energy reserve in the half plane space, transforming and transforming itself to obtain... Netherworld fog wall..."

This skill evolved from "ghost fog".

However, the system clearly said that only relying on the "ghost fog" upgrade can never improve this ability.

There are several preconditions to master the "ghost fog wall". First, you must master the ghost fog. 2、 Must have dark energy crystal nucleus. Third, must have enough space energy reserve or space system energy crystal nucleus. 4、 You must have the ability of "skill integration" in advance.

Coincidentally, Ye Yang met all the preconditions.

When I was promoted to Lv16, I chose "skill integration", but later I didn't have time to study carefully to integrate various skills. Unexpectedly, I actually need to use it now.

"Choose... Dark fog wall!!"

Netherworld fog wall is not a separate skill, but it can let Ye Yang form "netherworld ghost fog" into any form of body armor.

If light is nothing, if it is dispersed, it can form a fog wall to block the spiritual impact and energy impact, such as laser weapons, such as the high temperature and heat emitted by missile explosion. However, the fog wall will be destroyed, and the residual power can hurt Ye Yang. If you continue to consume mental energy to restore the fog wall, you can make the fog wall recover continuously.

After deducting a large amount of mental power at one time, you can resist a large number of attacks at one time. If the body is covered with such a fog wall in advance, the safety will increase a lot.

If the nether ghost fog is compressed and solidified into a film to block the body, it can be equivalent to a very tough protective cover, which can resist the stabbing of swords and guns. The hardness of the film is close to that of titanium alloy, which can be hard or soft. When it is soft, it does not affect joint activities. It is not afraid of knife and sword acupuncture, but it will be afraid of all kinds of heavy objects. When it becomes hard, it can resist the impact of blunt objects.

However, the solid membrane ghost fog will continue to consume mental power. Moreover, it can turn the membrane into a wall several centimeters thick, which also consumes mental power continuously. But as long as it is not attacked, it will not consume much mental power.

The above two forms can exist at the same time.

For example, a thin ghost fog film is added to the body, and there is a thin fog wall outside that can resist the impact of energy.

The ghost fog in the past can block infrasound waves and weaken a small amount of energy impact, but it is undoubtedly more powerful than the "ghost fog wall" now.

This power can't be obtained directly by raising the level of "ghost fog".

The reason why it is so powerful is that each fog particle contains weak space energy.

"After the level of the netherworld fog wall is upgraded, it can add more space energy transformed by spiritual force. Therefore, theoretically, it can become much harder than diamond... And even be as strong as the space barrier."

However, the space barrier cannot be worn like clothes.

"Very good skill." Ye Yang is very satisfied with this skill, because he uses the ghost fog too many times and is very familiar with it. It's better than acquiring a new skill.

"Unfortunately, the remote control distance of the nether ghost fog is still limited. Moreover, the skilled master Ba required to improve the level of the nether fog wall is integrated and superimposed with the nether ghost fog."

Ye Yang's mind flashed and continued to upgrade.

Lv19 is upgraded to lv20.

Ye Yang continued to add free points to the "intelligence" attribute.

As for the new skills to be acquired

Ye Yang pondered for a moment: "I don't know which one to choose. Well, high-speed thinking state... Mind outside... I need a strong mobile skill... Which one is better, which one is better..."

Ye Yang is interested in "accelerated surgery" and "advanced accelerated surgery".

The former can double the movement speed, attack speed and reaction ability of a group of creatures. But you'll get tired afterwards

The latter can double a creature's movement speed and attack speed. For example, Ji Yan, who can wield a knife 20 times per second with only 10% power, can wield a knife 40 times per second with only 10% power with advanced acceleration.

However, these two skills are powerful, but ye Yang feels a little dissatisfied.

So I want to get a reminder on a whim.

"Eh? Actually remind me to choose this skill? Isn't it cheating?"

Ye Yang stared at "Yin Qi lightness".

Draw the Yin Qi around you to yourself and you can reduce your weight by about 10%. As the level increases, the effect of this skill will continue to improve.

"Such a bad skill..."

Ye Yang hesitated.

The effect of reducing body weight by 10% is not great at all. The running speed will not improve much, and the reaction ability will not improve.

If you choose this skill, you may waste some skill points.

But

Ye Yang pondered for a moment and felt himself seriously. There was nothing unusual about a whim. Now he was not affected by any magic power, so

"Choose Yin Qi lightness skill!!"

Ye Yang chose this skill.

"Well, test..."

Ye Yang tried for a while and found that his body became dexterous. The previous weight of about 130 has now become less than 120.

But there seems to be no change in this gap.

"Did I choose the wrong skill?"

Ye Yang thought for a moment and suddenly felt a movement in his heart: "skill integration!!"

This is the skill you acquired when you upgraded to Lv16.

"Incredibly, can you integrate this' Yin Qi lightness skill 'with' nether ghost fog '?"

Ye Yang was surprised.

"Yin Qi lightness skill, after being promoted to lv10, can make you lose almost 100% of your weight and integrate with the nether ghosts and fog... You can get 'cloud flying skill'? That is to say... You can fly?

"However, the level of Yin Qi lightness skill is too low now, so... Using skill fusion consumes the energy crystal nucleus of dark system, the energy crystal nucleus of light system and the energy crystal nucleus of fire system and cold system. Four opposite forces restrain and influence each other, which can improve Yin Qi lightness skill to lv10, but it is unstable. You must immediately integrate with other skills and then disappear completely.

"Cost, a lot of upgraded energy and a lot of mental power are consumed. Yin Qi lightness will disappear forever, but the ghost fog can support itself and arbitrarily reduce its weight by 10% to nearly 100%!"

Ye Yang was shocked and couldn't believe it.

"Promotion, give me promotion!!"

Ye Yang was ecstatic.

After the skill is formed, quickly soar into the sky.

And, just running on the ground and controlling your weight, the speed becomes very fast.

However, the strong wind will cause damage to the body. For example, when it reaches the speed of sound, Ye Yang can't bear it.

But if it is combined with the nether fog wall as light as nothing, it is not a problem at all.

No matter how you run or jump, it's all right.

"Hahaha!!"

Ye Yang ran like a phantom on the ground.

Although the wind resistance on the face is large, it can be absorbed by the ghost fog, barely reaching the speed of sound and unable to break through the sound barrier.

You can wave your arm and break through the sound barrier easily. The wave speed is very fast, and the HP in your body is not damaged. Your body will not be torn.

"Well, you must have a very light and sharp weapon. But... I can't use it at all. This skill can be used to dodge the enemy's attack within a certain range. High speed thinking, combined with a whim, then the netherworld fog wall, and this cloud flying skill are... You can deal with Ji Yan face to face. You don't have to hide and play Yin at all!!"

How could this be a surprise?

Ye Yang pondered for a moment.

Calm down for a moment and decide to upgrade again.

In this promotion, Ye Yang did not choose to upgrade his skills from lv20 to lv21. Let's look at cross domain transmission first.

"Can it be improved? Can it really be improved? The cross domain transmission of LV1 is promoted to Lv2, and the effect..."

Ye Yang was silent.

It's too hard to choose.

I didn't expect that Lv2 transmitted across domains would be like this

"Can you choose to cross domain to another world?"

Ye Yang saw the explanation when he started cross domain transmission before

"Cross domain transmission (LV1): randomly specify a parallel space-time with similar historical background, bind it, and obtain the function of two-way transmission, which can shuttle between the two worlds at will."

Now you can get another chance to choose another parallel space-time to shuttle?

"Is it necessary to choose another parallel space-time? Other promotions seem good..."

Ye Yang pondered for a long time.

"It's time to think carefully..."
