Soon after the deal was concluded, Liu Kai returned to the attribute enhancement cabin and adjusted it to the skill upgrade mode.

Liu Kai didn't use the soul spar he obtained to upgrade his existing skills for the first time.

Instead, he took out the rest of the harvest from the [Storage Space] except for the [Navy Six Style] and the [Gate Fruit].

Yes, Liu Kai's harvest this time is not just the two who reached a deal with Zi Shiyi, Liu Kai actually has another harvest here.

For example, the two skill books in Liu Kai's hands at this moment.

[Additional Effect: Life Return: Use your own consciousness to infuse yourself and you can freely control your body, hair, and internal organs.] 】

[Introduction: This is the cultivation experience of the pioneers, and learning the knowledge in it can help you reduce the mistakes in your practice.] 】

To be honest, in fact, Liu Kai doesn't have much demand for the skill of [Yuebu].

Because although it can make itself fly into the sky, compared to being down-to-earth, staying in the air is not only not beneficial, but will make it more flawed.

Therefore, under normal circumstances, Liu Kai is actually too lazy to learn this skill, even if he can classify the [Moon Step], which was originally an active skill, into the [Fighting Mastery] and become his own skill.

However, after Liu Kai opened the [Rob Luqi's cultivation experience] from Rob Luqi's treasure chest, Liu Kai didn't wait to leave this skill behind.

Because compared to the gains that selling a [Yuebu] will bring to himself, the attraction of [Life Return] to Liu Kai is quite large.

As for why Liu Kai is so interested in [Return of Life]?

That's because [Life Return] can allow Liu Kai to reach a new level of control over himself.

Yes, compared with the effect of using his own consciousness to infuse himself to freely control his body, hair, and internal organs, Liu Kai actually values the control of himself more with this ability.

After all, for a person like Liu Kai who thinks that his body is the most reliable weapon, there is nothing more important than his perfect control of himself.

Don't even look at Liu Kai's control of his own skills at this time, he has actually become perfect.

After all, every time he strengthened his attributes, Liu Kai would spend a lot of time training his own control in actual combat.

But if he can learn [Life Return], then after adjustment, Liu Kai can ensure that his combat power can go to a higher level.

Therefore, in order to obtain such an ability, [Yuebu] Liu Kai cannot be sold.

In fact, if there is enough time, the ability to control oneself like [Life Return] can be mastered by Liu Kai himself after Liu Kai's meditation and body have developed to a certain extent. br>

But with the "Hell" and the Native World all urging him to become stronger, Liu Kai didn't have that much time at all.

Therefore, if you can learn skills to master some abilities that you can master in the future in advance, it may even be beneficial to yourself

loss, Liu Kai will not feel distressed.

Therefore, in the next second, after Liu Kai learned the [Moon Step] and achieved the requirements for the use of [Rob Luqi's cultivation experience].

Liu Kai immediately learned it.

And after learning and feeling the effect of being able to use his mind to perceive himself, Liu Kai suddenly showed a very obvious smile on his face.

"In this way, even if the attribute enhancement is too fast in the future, you don't need to spend a lot of time, hell gold, and energy to rely on combat to achieve control of yourself."

And this ability to perceive oneself is not only reflected in this aspect, but the rest of the aspects still need to be studied by Liu Kai little by little.

Therefore, after mastering this method in his hands, Liu Kai put it aside first, and then began to use the soul spar exchanged to strengthen his skills.

"After all, the next step will be to take back the [Mechanical System], so the strengthening of [Mechanics (Basic)] is essential.

However, after all, it has been decided that it will not use soul crystals to strengthen it a lot, but will focus on making equipment to gain experience and acquire knowledge.

And if everything goes well in the derivative world you want to go to, you can gain a lot of knowledge, so you just need to make sure that you have the qualifications to learn that knowledge."

So look at your skills:

[Mechanics (Basic, 1st Order)] LV.10→ [Mechanics (Basic, 3rd Order)] LV.31

[Mechanics (Basic, Third Order· LV.31): You have mastered the mechanical knowledge of the surface level civilization, and for you, you can learn and master the scientific and technological knowledge of the lower civilizations.

[Mechanics (Basic, 1st Tier) Rewards: Mechanical Armament Manufacture LV.1, Mechanical Energy Manipulation LV.1, Mechanical Virtual Manipulation LV.1]

[Mechanics (Basic, 2nd Tier) Reward: Elementary Mechanic Affinity: Mechanic Affinity +30%]

"In this way, in the derivative world that I plan to go to in the future, I should not be empty because of my own technological shortcomings that lead to entering Baoshan."

After spending 25 soul crystals to raise the [Mechanics] to such an extent.

Liu Kai began to shift his gaze to several other skills on his body.

"Because the next derivative is to prepare for the recapture of the [mechanical system], it is likely that the gains of the next derivative will not be enough to improve its own hard power.

And after the next derivative world, he needs to return to the original world once, although according to his own ideas, the danger after returning can be bearable, but he still can't be careless.

Therefore, the rest of the soul crystals should be improved as much as possible to a few skills that can significantly improve their combat power and survivability."

So, looking at the remaining soul crystals that were exchanged this time.

Liu Kai first used 10 soul spirits to raise the [Weakness Perception] to the highest.

[Weakness Perception] LV.10→ [Weakness Perception] LV.20

[Weakness Perception (Passive, Lv.20, Maxed Level): Enhances Perception and Perception Range, and increases the chance of catching flaws in enemy attacks and defenses by 15% during battle. 】

"Has it increased the chance of catching a flaw by 10%?" It's okay." After all, it's just a green quality skill, and you really can't ask for too much.

Then, after improving [Weakness Perception], Liu Kai looked at the other two skills that he could still improve at the moment, [Elemental Damage Resistance] and [Reinforced Iron Bone]

"Next, the focus will be on the increase of [Elemental Damage Resistance]."

As for why he chose this.

That's because compared to improving physical defense, which has equipment blessings and costs more, it is better for Liu Kai to improve his own shortcomings and spend less [Elemental Damage Resistance].

[Elemental Damage Resistance] LV.10→ [Elemental Damage Resistance] LV.45

Elemental Damage Resistance (Passive· LV.45): Reduces 32.5% of elemental damage dealt to self. 】

"There's not much soul hedron left." After looking at the skills he had improved, although he felt a lot of security, the soul spars consumed at the same time also made Liu Kai feel a lot of pain.

After all, the more than 100 soul crystals exchanged for the [Navy Sixth Style] and the [Gate Gate Fruit] had already exceeded 500,000 Hell Gold Coins at the market price alone, and after spending such a large sum of money all at once, how could Liu Kai not feel distressed.

And in distress, Liu Kai couldn't help but start to think stingily: "Hmph! The dog things of the boutique chamber of commerce have been so hard pressed by the price, see if I will trade with you in the future."

But although he thinks so, Liu Kai knows that people really don't cheat themselves.

After all, normally speaking, although the average price of soul crystals is 3,000 Hell Gold Coins.

But no one can really sell the soul hedron for 3,000 Hell Gold Coins.

Therefore, in the case of a full-rated purple equipment, it can only be exchanged for about 50 soul crystals.

It's already very good that people can price their own [Navy Six Style] for 40 soul crystals.

After all, even if [Navy Six] is a relatively valuable skill, the Hell Gold that can be exchanged for is still not worth a piece of purple full-rated equipment.

As for the [Gate Fruit], it is not to mention much, although it is also a bloodline item.

But as long as it wasn't for those few special Devil Fruits, most of the rest of the fruits were just to make up for their own weaknesses in the eyes of people in "Hell".

Therefore, in terms of value, being able to exchange for about 120 soul crystals is already very face-saving.

And you must know that in the past transactions with the boutique chamber of commerce, Liu Kai has actually taken a lot of advantage.

Therefore, if it is calculated in this way, Liu Kai is a little unbalanced in his heart because he consumes too much, otherwise he really let himself change, Liu Kai will not be able to exchange so much.
