The success of Shiyan on the little finger bone gave Liang Yu a certain amount of confidence, although the whole process was accompanied by pain, but this pain was much lighter than the pain of tempering the skin by the yin and yang winds.

However, for safety reasons, Liang Yu did not immediately start a comprehensive tempering.

Next, what he wanted to temper was the entire right arm, according to the previous shiyan, Liang Yu took out the corresponding amount of iron pith from the container, and then controlled the spiritual protective layer to wrap the iron pith evenly on the arm, and then quickly penetrated into the skin, directly covering the bones in the arm through the flesh and blood.

The process of fusion is naturally the same as before, but the degree of pain has deepened a lot.

After half a pillar of incense, the fusion of the entire arm was finally completed, and the marrow inside the bone all turned into a golden jade texture.

After a short rest, Liang Yu began to continue to fuse the other parts.

Half a day later, after using up those iron pith, Liang Yu also fused the bones of his whole body. However, due to the limitation of the amount of iron pilac, only the fusion of bone marrow was completed this time, and the extremely high-quality bone marrow of jade golden pilacy was finally formed.

After seeing Zuihou reach this level, Liang Yu was still a little helpless in his heart, it seemed that just fusing the iron pith once was not enough to immediately carry out the tempering of the second turn. As a result, the search for new materials will continue to be carried out, and at the moment, it seems that the most likely thing to find is the rootless wood! As for the dragon's beard grass, it will only be considered when it is a last resort.

However, he couldn't go looking for the Rootless Wood right away, as he still needed to wait for the Fire Cloud Beastmaster to pass the Transfiguration Tribulation, and then take this guy with him. Because, a shape-shifting aura beast master can greatly improve the success of the next search activity.

While waiting, Liang Yu was not completely idle, he began to absorb the relatively rich spiritual power around him in an appropriate amount, after all, it is not a bad thing to absorb more spiritual power!

A week later, Liang Yu, who was calmly absorbing spiritual power, suddenly felt a magical change in his surroundings. A sense of oppression from the depths of the soul suddenly emerged.

"Transformation Tribulation!" Liang Yu immediately understood what was about to happen.

Sure enough, soon Liang Yu saw the Fire Cloud Beast King, who had been prepared and was about to face the Transformation Tribulation. The creature had flown out of the bottom of the magma lake, hanging high in the air, and at the same time completely unleashing its momentum, and seemed to be fully prepared.

Soon, dark clouds enveloped the sky. And before that, Liang Yu had already left this area far away and ran outside the area covered by the clouds, otherwise he would be implicated. If that's the case, it's not a good thing for either the Fire Cloud Beast King or Liang Yu himself.

After about half a pillar of incense, the thunder tribulation finally began.

After all, he didn't cross the catastrophe himself, so Liang Yu didn't feel worried at all. Moreover, in his opinion, as far as the Fire Cloud Beast King is concerned, in fact, the liliang accumulated by this guy has long exceeded the need for transformation, but due to some special reasons, he has not been able to transform smoothly, so this transformation tribulation should not pose much of a threat to him.

Sure enough, soon the first three thunder tribulations were easily passed by the Fire Cloud Beast King, and not even a little damage was left on its body.

However, the power of the fourth wave of thunder tribulation was obviously much stronger, and finally forced out some of the hole card methods of the Fire Cloud Beast King. In the end, while it survived, it still left a lot of damage on its body! One of its claws was shot down, only to be regrown by its magic power of regenerating with severed limbs.

Then there is the fifth wave, the sixth wave, these two waves of thunder tribulation also made the Fire Cloud Beast King extremely embarrassed, and after the sixth wave is over, half of this guy's body has even been blown up by the thunder, even after the regeneration of broken limbs, it will only be restored to a small part, and a big tail is missing!

However, looking at the situation in the sky, this guy's transformation tribulation does not mean to end. In fact, Liang Yu was not very familiar with the transformation tribulation of the aura beast, and he didn't know how many waves of thunder attacks he needed to experience, but it was certain that it would definitely not be simple.

The seventh wave of attacks could already be regarded as a thunderstorm, and countless thunderbolts fell from the sky and slammed into the body of the Fire Cloud Beast King. Such an attack made Liang Yu seem to feel a trace of fear and pain.

However, as an existence of a king, the Fire Cloud Beast King is not an idle person, and after some hard work, he still survived under the attack of the seventh wave. However, at this time, he has really reached the point of exhaustion, and if there is another wave, it is estimated that he will definitely die!

However, it seems that this guy's good luck has finally arrived, and his transformation is over.

The dark clouds in the sky began to be replaced by colorful clouds, and then a thick colorful beam of light fell from it and directly enveloped the Fire Cloud Beast King, and then began to repair this guy's already somewhat tattered body, and at the same time began to change the structure of the muscles in the body.

Liang Yu is still very familiar with this colorful beam, it was the baptism of this colorful beam that he was reborn twice. However, this time, he didn't plan to grab these colorful beams with the Fire Cloud Beast King, because after all, this was a reward from heaven that belonged to the other party after experiencing the Thunder Tribulation.

However, at this time, a message from the Fire Cloud Beast King suddenly came from Liang Yu's divine sense, allowing him to properly absorb some of the colorful light scattered by this seven-colored beam. Because it can't absorb all the colorful light by itself, Lang Fei is also a white Lang Fei.

After receiving the message from the Fire Cloud Beast King, Liang Yu was no longer polite. So, he stimulated the gluttonous devouring supernatural power, and a huge gluttonous statue rose from behind him, and then began to absorb the colorful light.

However, Liang Yu passed on a consciousness to the gluttonous image, that is, he only absorbed those discrete seven-colored light particles scattered in the air, and did not compete with the Fire Cloud Beast King for the main seven-colored beam.

However, Rao is like this, and the absorption of gluttonous images is also considerable.

Liang Yu found that all the colorful lights that were absorbed were fused into the bones, and after the bones absorbed these colorful lights, the quality began to continue to improve.
