Just when the ape spirit looked at the silver stick in his hand, a large amount of white mist suddenly appeared from the crack on the ground, and the white mist was purely composed of spiritual energy, especially the place where the silver short stick was inserted before was directly sprayed out of the white mist, which immediately filled the entire cave.

The ape spirit was startled by the sudden change, and quickly inserted the silver stick in his hand back, but it didn't help, the cracks on the ground became bigger and bigger, more and more white mist came out, and the whole cave also trembled, and the originally dim spirit stone released the last spiritual power, and the light mask reappeared, but it was already nothing, as if it would be broken at any time.

The violent shock made the demon beasts stand unsteadily, and the spirit stone embedded in the cave wall turned into powder and dissipated after consuming the last trace of spiritual power, the light mask became more unstable, and the stones fell and smashed on it and shook violently, the light was bright and uncertain, and it could be broken at any time, and all the demon beasts and demons present at that time would be buried alive, although they were physically strong, but they still couldn't survive if they were buried alive here, and all the demon beasts and demons panicked for a while.

The ape spirit is still in danger, although he is also nervous, but he still calms down, looks around, and knows that it is too late to go out now, the ground tremors are too strong, there are no flying monsters or demons present, which makes them unable to run fast, and now the only thing that can make them survive is the layer of light mask, as long as the light mask is not extinguished, the cave will not collapse, and they don't have to worry, and after these days of observation, he knows that the light mask is powered by the spirit stone inlaid on the cave wall, and now the spirit stone has consumed all the spiritual power, and the Xuan-level spirit stone has all turned into powder, and only the ground-level spirit stone is struggling to support。

The ape spirit did not hesitate at the moment, the light in his hand flashed, and at the same time, the throwing stones that he had practiced for many years played a role at this moment, only to see the spirit stones made into a ray of light accurately embedded in the original spirit stone embedded, this time the ape spirit was not stingy, and all the things that were taken out were heaven-level spirit stones, fortunately, there were still a lot of space rings, enough to embed all the vacancies, and each spirit stone was the same as the previous spirit stone attributes, at this moment, the ape spirit could not take risks, and could only take the safest method.

Each heavenly step spirit stone inlaid into the cave will shine, the original crumbling light mask immediately stabilized, even the constantly shaking ground has become stable, seeing this ape spirit is overjoyed, but the hand does not stop, with the sound of ding ding ding a few breaths will be empty depression all inlaid spirit stones, with the support of these highest-quality spirit stones, the light mask does not have to worry about being broken, so that the ape spirit is also a little relieved.

It's just that although the light mask stopped the shaking of the cave, it still couldn't stop the aura from coming out, the entire cave was shrouded in white mist, and he couldn't see his fingers at all, and the rich spiritual power drilled into the flesh of the crazy king with his skin, and every breath he took inhaled a large amount of spiritual energy, which made the ape spirit suddenly feel extremely comfortable, and the aura that drilled into the body was absorbed by the demon pill and the surrounding spiritual liquid, and the demon pill became more and more transparent, and the spiritual fluid also grew at a visible rate to the naked eye.

The ape spirit knows that this situation is suitable for a breakthrough now, anyway, he has entered the peak of the pregnancy pill, and he can break through to the bone forging period at any time, and every breakthrough requires a large amount of spiritual power, there is so much at this moment, and pure spiritual energy is provided, when will it not break through now.

So the ape spirit immediately shouted, "Start cultivating immediately, if you can break through, don't hesitate, now this place is full of pure spiritual power, and cultivating here is better than eating any spirit pill." After speaking, he didn't say much, sat down cross-legged directly, and began to practice the anti-heaven technique, the demon consciousness entered the demon pill, and a large amount of demon power was spewed out from the demon pill, running in the body, and at the same time absorbing the aura drilled into the body, other demon beasts and demons did not hesitate to hear the words of the ape spirit, and immediately entered the cultivation, fortunately, there are nine demon beasts and six demons cultivating at the same time, one of them is about to break through to the bone forging period, plus the heavenly step spirit stones embedded in the cave wall of the ape spirit have also absorbed this pure aura, and the aura that emerged for a while and the absorbed can reach a balance。

The ape spirit did not stop running the demon power in the body for nine hundred and eighty-one days, but continued to operate, but this time it was different from usual, even if the demon power continued to grow after eighty-one weeks, it was obvious that the growth of each operation week was obvious, and this operation was different from usual, and the demon power that spewed out did not enter the demon pill, half of which was integrated into the muscles and bones during the operation, and in the end, only half entered the demon pill. With the increase of the operation week, this proportion is still increasing, the ape spirit knows that this is the precursor to entering the bone forging period, only when the demon power spewed out is all absorbed by the muscles and bones, even if it breaks through to the bone forging period, then the demon power in the demon pill will not increase, nor will it decrease, every time the hand washing aura replenishes the part consumed, the excess will be integrated into the muscles and bones, during which the demon pill will slowly absorb the surrounding spiritual fluid, and when it absorbs all the spiritual fluid, it will enter the pregnancy and infant period, so the amount of spiritual fluid in the early stage determines how high the quality of the demon baby is, and it will also determine how high the achievement will be in the future, and the spiritual fluid will also stop with entering the bone forging period, so the ape spirit originally planned to find a place with a strong aura to break through, but who knew that this kind of thing would be encountered, and all the problems would be solved.

The ape spirit used the demon power over and over again in the body to rotate, most of the demon power was absorbed by the muscles and bones, and the original ordinary bones slowly emitted a layer of smoothness with the immersion of aura and demon power, and the impurities in the bones also became a trace of black gas coming out, and then radiated to the outside of the body through the pores, and even the flesh and blood around the body also came out of the body with a little black gas along the pores and discharged out of the body, with the discharge of these black gases, the body of the ape spirit slowly shrank again, and the bones in the body slowly shrunk, but the density slowly increased, and the density became larger。

I don't know how many weeks of operation, now the muscles and bones of the whole body have absorbed all the demonic power in the demon pill, shrouded by a layer of faint white light, and you can also see a trace of spiritual energy slowly fused into it, and at the same time, the empty demonic power also keeps absorbing the spiritual energy to recover the consumption, and the surrounding spiritual liquid also keeps absorbing the spiritual energy, only when the white light wrapped around the muscles and bones is all absorbed by the bones, it can be regarded as a complete breakthrough.

Just when the ape spirit broke through, the caterpillar was also sprinting to forge bones, originally he and the ape spirit's cultivation was not much different, just entered the cave and was forced to break through like the ape spirit, but he only reached the late stage, and did not enter the peak, and the gap between the peak and the later stage is the accumulation of demon power, and now this sudden pure and huge aura just allows the caterpillar to absorb and precipitate the demon power, originally it thought that it would be good to be able to reach the peak this time, but unfortunately he still underestimated the aura that came out this time, only to see that when he entered the peak, the aura still continued to enter the body, so that he directly sprinted directly to the bone forging period, Although this kind of successive breakthroughs may lead to an unstable foundation, but Qi is strange here, the breakthrough in this cave does not have to worry about causing the foundation to be unstable, and the demon race is not like the human race to break through to the realm, as long as the physical conditions are enough, you can break through to the next layer, and the realm will also rise together, maybe this is another way for the heavens to make up for the demon race.

It's just that the caterpillar doesn't have bones, so when he broke through to the bone forging period, it was his burrs that he exercised, and at this moment, the caterpillars were all wrapped in a layer of white light, and there was a massive amount of aura integrated into it, and it seemed that it had entered the final stage of breakthrough like the ape spirit.

Besides, the tiger next to him can be said to be majestic, the hair on his body is windless and automatic, the king pattern on the top of his head is like a flame jumping, the breath belonging to the king of beasts is emanating, the original huge body is also slowly increasing, slowly shrinking, every time it shrinks, there will be a black gas coming out of the body, and at the same time, a ball of light shines on the lower abdomen, it is obviously in the Ning Jie Demon Pill, not only it, other demon beasts have also begun to condense the Demon Pill, as for the other condensing Demon Pill, they have begun to break through steadily, there are so many demon beasts and demons breaking through at the same time, and the aura in the cave is also slowly decreasing。

Looking at the round neck, I saw that the white light that wrapped the bones was slowly absorbed, and the demon pill at the dantian had also been restored as before, and the demon power contained in it was larger and purer than the pregnancy pill period, and the surrounding spiritual fluid was also completely filled with the entire dantian slowly, and the whole spiritual fluid was extremely viscous, and there was no trace of flow at all, as if solidified, it can be said that with such a spiritual liquid, the demon baby bred by the ape spirit must belong to the upper selection, at least it is also a ground level demon baby.

In the demon clan, the demon baby is also divided into four kinds of heaven and earth, Xuanhuang, of course, the yellow level is the lowest level, and the demon clan with this kind of demon baby will generally not have much achievement, unless there is a big opportunity, it can only reach the out-of-body period at most. And the Xuan-level demon baby is better, and has the opportunity to cross the tribulation, but the success rate is extremely low, and it can be said that there is no one in ten thousand, so there will be no great achievements. But it's different to have a ground-level demon baby, as long as the demon clan that gives birth to a ground-level demon baby can generally reach the tribulation period, and the success rate of the tribulation is also very high, basically one tenth, which is much higher than that of humans, even if the genius among human monks is only this rate. As for the heaven-level demon baby, it is even more incredible, as long as it is successfully conceived, it will become a demon saint, which is a stronger existence than the demon fairy, even during the demon war, there are only a handful of demon saints, and none of the demon saints died, all disappeared by themselves, no one knows where they went, the common saying is that they were seriously injured and all died.

When the white light is completely absorbed by the bones, the bones are as white as jade, a transparent film covers the surface of the bones, a faint light flows in it, and the surrounding flesh and blood have become abnormally human, and the fur on the whole body exudes metal rigidity, and now the defense power of the ape spirit is extremely amazing, and the claws of ordinary demon beasts cannot cut his skin. These are not comparable to human beings, no matter how advanced the realm of the cultivator is, if you rely on the strength of the physical body alone, you think that the master of the Mahayana period will not be able to fight with the little demon in the bone forging period, and the forging of bones, as the name suggests, is to strengthen the muscles and forge the bones, only the physical body will withstand more demon power, so if the demon beast is grasped at the right time, it can kill people beyond the ranks.
