The effect that is happening on this bone is something that is truly and truly embodied in the mystery of life and death!

This is not a fragment of the rules that seem to exist in the token of life and death.

This mystery of life and death, in this primordial secret realm, can actually evolve into substance, perfectly embodied on the broken bones of a skeleton, and the transformation of life and death contained in it is the place where Qin Chengming needs to learn and understand the most!

Qin Chengming just put the broken bone on the center of his eyebrows, he immediately felt the broken bone, in the two different bones, there is a very different death qi {not spiritual power}, it has become the same source of life qi, these two life qi have the same origin, in order to connect the broken bones of two different materials together, and then, the life qi will slowly dissipate, and it will become the death qi again, and the broken bones will also be successfully docked, and they will grow together completely.

That is to say, Qin Chengming came relatively early, if Qin Chengming came one step late, all these seemingly innocent angry qi would disappear, and Qin Chengming would not be able to know that these skeletons still have such value.

After a long time, when all the life qi on this skeleton was gone, it also lost its research value.

Letting go of this broken bone that had no research value, Qin Chengming stood up and stared around carefully.

As long as there was a moving skeleton around him, Qin Chengming would pounce on it without hesitation, and take it apart to see how the mystery of life and death formed by the combination of the qi of life and the qi of death was transformed......

After waiting for a long time, Qin Chengming's eyes were sour, and finally, a skeleton stood up in the distance, it only stood facing Qin Chengming for three seconds before it fell.

Qin Chengming's legs burst out with all the strength of his flesh and rushed towards the skeleton.

After Qin Chengming arrived at the place where the skeleton was, he saw that the skeleton was still trembling slightly, and it had not lost the ability to move, Qin Chengming was overjoyed, and directly tore off one of the leg bones of the skeleton and put it on the center of his eyebrows to understand it carefully.

Qin Chengming entered a black and white microcosm, this is a horizontal and straight 'river', the two ends of the river are jet-black death qi, and the center of the river is the life qi that emits white light.

Carefully comprehended, Qin Chengming could only see that when the black death qi of the river flowed to the middle, it automatically turned into a white life qi, as for how it changed, Qin Chengming couldn't see it clearly.

This made Qin Chengming anxious, his eyes were motionless, staring at the three 'qi' that were constantly circulating.

Then, as the white life qi in the middle became more and more dim, the death qi also increased......

Five minutes later, in this microcosm magnified by the leg bones, there was no trace of white life qi, all of them were rich death qi.

Qin Chengming frowned, the changes inside this bone were not the kind he wanted.

He was still late, so he could only see the scene where the qi of life turned into the qi of death, and he couldn't see how the qi of death turned into so much qi of life, and these were actually useless to Qin Chengming.

Because it is very easy to change from birth to death, just one word: "wait", on the line, the evolution of the qi in the bones is also in line with this word.

But changing from the qi of death to the qi of life is the most critical difficulty, Qin Chengming doesn't want to say that he hasn't seen it yet, even if he really sees it, he may not be able to realize it at once.

However, Qin Chengming still has to try his best to see it, because this death and rebirth of the mystery of life and death has been learned, and it is very likely to help Yayun resurrect.

Qin Chengming stood up, this time, he didn't use his eyes to see which skeleton could move, but closed his eyes and listened with his ears, he wanted to hear where there was a sound in this sea of bones, and then rushed over as soon as possible.

The hard work paid off, and when the sound of squirming sounded in the sea of bones in the distance, Qin Chengming suddenly opened his eyes and looked there.

In that sea of bones, many broken bones and broken bones began to gather, and they looked like they were slowly about to be put together into a human form.

Qin Chengming had already used all the strength of his body to run there, and when he arrived, he was pleasantly surprised to see that this skeleton was still emitting white light.

In particular, the thigh bone of this skeleton is made of broken bones of two different materials, and at this time, the white halo is extremely obvious at the intersection of the section.

Qin Chengming didn't hesitate, snatched its thigh bone and put it on his eyebrows.

The skeleton lost its thigh bone and could no longer stand, it fell into the sea of bones all of a sudden, and then, its hands followed Qin Chengming's appearance and pressed it on the center of its eyebrows......

Qin Chengming's spiritual sense suddenly entered the microcosm of this leg bone, Qin Chengming only saw that in this leg bone, a black river condensed by the qi of death, but inside it was white qi of life.

Then, the breath of life steamed up, turning the river into a state of two black and one white.

When these changes occurred, Qin Chengming didn't just look at the surface, he carefully felt the operation of the white life qi and the cooperation of the black death qi, and then, a trace of understanding came to his heart.

It turns out that the mystery of life and death does not necessarily have to act on spiritual power to form life spiritual power or death spiritual power, it can also act on the qi of life and death, and even on everything in the world and everything that is alive.

Qin Chengming opened his eyes, his eyes were like torches, he picked up an ordinary half-jade rod bone full of dead qi, and then, with his understanding of the mystery of life and death, he changed the death qi inside and turned it into the life qi.

As Qin Chengming's spiritual sense stirred the qi of death with a special law, in the center of the rich qi of death, a trace of the qi of life that was so small that it was almost invisible was born, and this qi of life, although it was small, proved that Qin Chengming's perception was right.

Qin Chengming continued to use his divine sense to regularly generate more vitality, and as Qin Chengming became more and more proficient, a rich white brilliance appeared in the middle of the stick bone in his hand.

Just when Qin Chengming's heart was excited, thinking that there was hope for resurrecting Yayun, the stick bone in his hand suddenly clicked and exploded from the middle, bursting out countless bone foam and bone fragments, spraying Qin Chengming's head and face.

Qin Chengming opened his eyes, and saw that the original half-jade rod bone in his hand had been blown up at this time, and its two ends had also turned dead gray......

Qin Chengming stared at the stick bone in his hand and was silent for a long time.

A tear fell from his sad face, and he now had a deeper understanding of the meaning of life and death.

He knew that the resurrection of Yayun ...... This matter is very long, so long that even if the mystery of life and death is comprehended, it may not be successful, this is Qin Chengming's current understanding.

Not because of anything else, but because the rules of life and death, or the way of life and death, stipulate that only the living can give birth to the living.

But what Qin Chengming wants to do is to turn the dead into the living, this kind of behavior is going against the grain.

So it is not so much that Qin Chengming used the mystery of life and death to resurrect Qi Yayun after comprehending the mystery of life and death.

It's better to say it more clearly: Qin Chengming comprehends the mystery of life and death in order to thoroughly understand the rules of life and death, the avenue of life and death, and then, Qin Chengming can rely on his understanding of the avenue of life and death, and by confronting the mystery of life and death, he uses the behavior of the opposite way to snatch back Qi Yayun's vitality!

It's like if you want to defeat your enemy, you have to know him first, and the best way to get to know him is to follow him, and when you know him thoroughly, you will know how you should fight him......

Qin Chengming didn't fully understand the mystery of life and death, he only learned through that stick and bone that if a person who has died forcibly reverses his vitality, the things he destroys will also bring a stronger death, and he can't fight it.

For example, the stick bone, Qin Chengming restored it to life, using the death qi inside it to do so.

However, the reason why the bone was hard in the first place was also because of the death aura inside it.

In order to restore that short period of vitality, Qin Chengming used up all the death qi inside him, and the original jade color of the stick bone was also destroyed, and its internal structure also collapsed and turned into powder.

Because it's dead, there's so much energy inside it that it can't be replenished in other ways, and when the energy runs out, it's really used up.

It is not like a living person, and it has the ability to replenish new energy on its own.

In the same way, the resurrection of Qi Yayun is the same, Qin Chengming can also use her body to mobilize her vitality, but this vitality is not endless, but is transformed by force, there is no 'spirituality', and when the vitality dissipates, Qi Yayun's body may also be wiped out......

In the final analysis, this method is the embodiment of the mystery of life and death, so how can it be successful to use the mystery of life and death to do things against the mystery of life and death.

At this time, Qin Chengming understood the intention of the Primordial Secret Realm, the sea of bones here, as well as the moving skeletons, should be to facilitate the disciples who came here to comprehend the mystery of death.

If those disciples could do everything that Qin Chengming had done, then they should be able to condense the Necromantic Sword Embryo, and some truly top-notch cultivators would be able to comprehend how to use the Necromantic Sword Embryo to further transform into the Life and Death Sword Embryo through the change of Dead Qi into Vitality.

The mystery of life and death here, to put it bluntly, is like this, and it has little effect on Qin Chengming.

However, after all, these moving skeletons are still quite interesting, Qin Chengming didn't plan to waste these two days, he simply grabbed the little skeletons one by one, and in this primordial secret realm, he felt it for two days and two nights.

When the time of two days came, Qin Chengming showed a smile on his face.

He had already thought about what kind of answer sheet he wanted to hand over on that spirit test stone.

As the following second came, a small teleportation array appeared on the soles of Qin Chengming's feet, and then a white light flashed, and Qin Chengming reappeared in the ravine.

The sun in the morning, Qin Chengming couldn't get used to it.
