For a whole day, Zhang Xiaoyu barely went out, just nested in the room, studying Sanskrit.

Three o'clock in the middle of the night.

The books about Sanskrit collected by the chef here are almost read, and Zhang Xiaoyu's understanding of Sanskrit has also deepened a little.

Although I can't be proficient yet, it's enough to study the Vajra Technique and the Great Freedom Heavenly Demon Skill.

At least, it won't be the same as before.

Without thinking much about it, Zhang Xiaoyu hurriedly closed his eyes and began to study the cultivation method of the Vajra Jue.

This exercise, until now, Zhang Xiaoyu doesn't know what grade it is.

But come to think of it, it should be more advanced than A's quenching bones.

Quenching bones is also a type of genetics, which is the same as breathing.

Zhang Xiaoyu only has a C-level guidance technique, and other than that, he has not exchanged for other genetic techniques.

As for secret arts, he has no interest in them for the time being, and in terms of tactics, he is not prepared to waste time.

With punching, plus the perverted version of the cook's training, tactics and the like, it's a bit redundant.

Moreover, he is now practicing with the cook, and the boxing gloves have become the mainstream weapons, plus bows and arrows, other weapons do not need to be considered for the time being.

Thinking of the bow and arrow, Zhang Xiaoyu remembered the sky-breaking magic arrow that the cook taught him last time.

At that time, after casting the Heaven Breaking Demon Arrow, Zhang Xiaoyu didn't expect that the power would be so terrifying.

And now he has only mastered the skin, and the cook has not taught him all the methods of using the Sky Breaking Demon Arrow.

According to the cook, Zhang Xiaoyu's current physical fitness is not enough to support the complete version of the Heaven-Breaking Demon Arrow.

Once it is used, before the sky is broken, Zhang Xiaoyu himself may be sucked dry.

Therefore, the sky-breaking magic arrow cast by Zhang Xiaoyu behind him is simply empty and ungodly.

Moreover, the cook also said that although the bow and arrow in Zhang Xiaoyu's hand is not ordinary, it is still too far behind to cast the sky-breaking magic arrow.

"The cook is so stingy, he must have wanted me to pass on his boxing skills, and he didn't want me to practice bows and arrows. ”

Zhang Xiaoyu muttered, and didn't think about it anymore.

If you can't beat the cook, if the cook doesn't teach, he can't help it.

After thinking about it for a while, Zhang Xiaoyu put down all these messy thoughts in his mind and began to study the Vajra Technique.

It wasn't until the early hours of the morning that Zhang Xiaoyu opened his eyes.

There was no hint of tiredness in his eyes, but a look of excitement.

After several hours of research, he finally studied the Vajra technique thoroughly.

This vajra technique is a special body refining method, refining the body, not just for quenching bones.

The reason why I say this is because the cultivation of ordinary martial artists basically only quenches the bones, and rarely quenches the bones.

The warrior realm and temper the bones of the limbs.

When you reach the warrior realm, you will refine your torso bones.

When the trunk bones and limb bones are quenched and a natural cycle is formed, the refining of the five internal organs can be considered.

The martial artists of the War Emperor Realm, when refining the internal organs, will also temper the muscles and meridians by the way.

As for the higher realm, Zhang Xiaoyu didn't know.

To quench the meridians and muscles, you need to quench the body, and this thing is the same as quenching the bones, which is also a kind of genetics.

The reason why low-level martial artists only choose to quench bones and not quench their bodies is because of resources, and on the other hand, quenching bones and quenching bodies at the same time will increase the cultivation time.

It is possible that others have completed six bone quenching in two or three years and entered the realm of war generals.

For those who also cultivate the body, it will take four or five years, or even longer.

Of course, body quenching must be carried out, but low-level martial artists rarely do it.

Generally speaking, when a martial artist arrives at the Battle Emperor Realm, the limbs and torso bones are completed, and the tempering of the five internal organs is completed, at this time, the improvement of cultivation will also enter a bottleneck period.

At this stage, the martial artist is not in a hurry to quench his bones, and has a lot of time to study the tactics, temper the meridian muscles, and plan for the next step of advancement.

And Vajra is different.

Vajra can temper both the bones and the flesh at the same time, provided that you have enough resources.

Moreover, once you start practicing, there is no possibility of stopping this exercise.

Zhang Xiaoyu didn't know if what was said above this exercise was true or false, but he didn't mean to practice the law with his body.

Anyway, if you exchange for a high-level bone quenching decision, it will cost thousands or even tens of thousands of credits, and with the Vajra Jue, these credits can be saved, and if the fruit of life appears, you will not panic.

The Vajra formula is divided into eight layers.

Zhang Xiaoyu took a general look, this exercise should not be a complete version, because after the eighth layer, it is obvious that there are still things, but Zhang Xiaoyu has not gotten it yet.

However, since this exercise comes from Buddhism, you can consider going to Buddhism in the future.

The cultivation of each of the eight layers of exercises is different.

The first layer is the entry, that is, the bone quenching method that Zhang Xiaoyu practiced before.

Crush the meridians, increase the flow of qi and blood, thereby speeding up the bone quenching process, more than ten times of bone quenching, the first layer can reach the realm of Xiaocheng.

Twenty times to quench the bones before entering the realm of Dacheng.

Zhang Xiaoyu smacked his lips.

Twenty times to quench the bones, the person who created this exercise, I am afraid that there is a mine at home, and it is still that kind of huge mine.

The cultivation of the first layer only needs to consume the power of qi and blood.

From the second level onwards, this practice has completely changed.

The cultivation of the next seven layers did not elaborate on the requirements for the number of bone quenching.

However, the cultivation of the last seven layers requires the use of some special spiritual objects, and the higher the level of the spiritual objects, the more obvious the effect of cultivating this exercise.

The second layer of cultivation is used by metallic spiritual objects.

A few layers in the back, Zhang Xiaoyu didn't look at it.

"Metallic spiritual object, I wonder if this kryptonite can satisfy the cultivation of the second layer after eating?"

Thinking of the kryptonite long knife he had obtained from Pan Xiaolei before, Zhang Xiaoyu's heart moved, and he had a bold idea.

"Forget it, krypton gold is only an alloy after all, and my teeth are not that good, metallic spiritual objects, the exchange department doesn't know if there is. ”

Zhang Xiaoyu secretly thought to himself, temporarily put down the cultivation of the Vajra Technique, and began to study the Great Freedom Heavenly Demon Skill.

Compared with the Vajra Jue, the Great Freedom Heavenly Demon Gong is even more obscure.

It wasn't until noon that Zhang Xiaoyu understood a large part of it.

As I saw before, the cultivation of the Great Freedom Heavenly Demon Attack must rely on demonic qi or other dark aura things.

Moreover, it is very clear from what this exercise says above that to cultivate the Great Freedom Heavenly Demon Skill, the cultivator must have strong willpower, otherwise he should not try it lightly.

If the willpower Borui cultivates, once he goes mad, he is likely to fall into hell, and the path of reincarnation will be buried.

Reincarnation or something, Zhang Xiaoyu didn't care.

This thing is simply nothingness, could it be that there is still an underworld in this world?

Amusing.

People can't be resurrected after death, and the idea of reincarnation is too absurd.

What he really had a headache was the demonic qi or dark aura needed to cultivate this exercise, and he had no clue at all.

"Breath of Darkness ......"

Zhang Xiaoyu muttered, lost in thought.
