"Let's start with this unicorn bone in the Shenque Cave now, which avoids many vital points of the body and is less risky. ”

After putting down the wine bowl, Yu Xuzi's expression also became serious.

"Good. ”

Li Yunsheng nodded.

"Wait a minute, even if you refine, I'll help you stabilize the seal of the Qilin Bone, so that you don't have to worry about him flowing around in your body. However, this time it is transformed into Yin and Yang Qi in the Qilin Bone in your body, and not only your body, but also your soul may also feel pain, so remember not to be disturbed by the pain. ”

Yu Xuzi then admonished.

"Thank you, Uncle Shi reminded me, I have worked hard. ”

Li Yunsheng nodded again, and then said with a firm gaze:

"Then I'll get started. ”

"Good. ”

Yu Xuzi nodded in the same affirmative.

Immediately, Li Yunsheng took a deep breath, then closed his eyes, and began to look inside his body with the power of his divine soul.

He first took a closer look at the location of the bloodline mentioned in the Qilin Bone Refining Method, and then began to immerse his divine soul in the Qilin Bone little by little.

The scene inside the unicorn bone is like an endless golden ocean.

And what Li Yunsheng has to do now is to "ignite" this ocean of true yuan.

And also at the fastest speed.

Thinking of this, he began to concentrate on recalling the essence of the exercise that transformed the true element into yin to yang qi.

This can't blame him for being so cautious, after all, he was on the boat before, but this time it was in his own body, and if he made a slight mistake, it was really a bone ruin.

About a moment later, the first flame rose in the golden sea inside the unicorn bone.

This small flame shook in the center of the golden ocean for a few moments, and then suddenly spread, like a torrent that instantly swept through the entire Qilin Bone.

"Young people are just motivated. ”

This kind of speed, even Yu Xuzi, who was protecting the Dharma on the side, couldn't help but praise in his heart.

Of course, just this level of flame naturally can't melt the Qilin Bone, but there is no need for Yu Xuzi to remind you that the color of the flame in this Qilin Bone is fading at a speed visible to the naked eye under the urging of Li Yunsheng, and in the end, the flames in the entire Qilin Bone have turned into a clear and transparent white.

According to the description of Xuanyuan Night Rain's exercises, this white flame is what it looks like when the flame temperature is at its highest.

At the moment when the white flame appeared, on Li Yunsheng's body, the runes that were originally used to seal the Qilin Bone began to fade little by little, and finally dissipated completely.

Losing the control of the seal, the unicorn bone began to show signs of loosening in Li Yunsheng's body.

Yu Xuzi had been waiting for this moment for a long time, and at the moment when the runes disappeared, he immediately stretched out a finger and put a little on Li Yunsheng's body, and countless runes immediately overflowed from his fingertips, once again firmly locking the unicorn bone in Li Yunsheng's body.

At the same time as he re-locked the unicorn bone, the unicorn bone began to soften under the cautery of the high temperature of the white flame inside, turning from a hard unicorn bone into a boiling magma-like mass.

At this time, just as Yu Xuzi reminded earlier, Li Yunsheng began to suffer from the attack of the double pain of the divine soul and the body, this pain was far from being comparable to the pain of breaking muscles and bones, but was very similar to the pain of the soul being peeled.

The key to this kind of pain, Li Yunsheng can't forcibly cut it off with his divine soul, so he can't control the supreme yang qi in the qilin bone.

While enduring this painful attack, he also divided a divine soul, ripped off the blood veins, and connected them with the unicorn bones that had melted.

Because the bloodline that Xuanyuan Yeyu required to fuse with the Qilin bone was too much and too complicated, this process lasted for about three hours, which means that Li Yunsheng persevered for three hours under this pain.

After three hours, all the meridians and blood vessels were fused with the unicorn bone as required.

Li Yunsheng, who had already turned pale, began to prepare to complete the last step, which was also the most important and difficult step, that is, to transform the white flame in the Qilin bone into a frost flower of the power of yin at the fastest speed.

After taking another deep breath in his heart, Li Yunsheng directly transferred all the divine souls he could mobilize in the state of three silences, as if he wanted to turn this piece of heaven and earth upside down, and released it in one go.

In the end, in just a split second, the white eyes in the entire unicorn bone were all transformed into cold frost flower ice crystals, and the entire world was frozen in ice, including the unicorn bone and the meridians that merged with it.

"Hoo ......"

At this point, Li Yunsheng opened his eyes and exhaled a long mouthful of cold turbidity, and the moment this turbid breath came out of his mouth, it immediately turned into pieces of ice crystals and landed on the boat.

"Two hours faster than I expected. ”

Yu Xuzi looked at Li Yunsheng with admiration in his eyes.

"Uncle Shi has won the award. ”

Li Yunsheng smiled bitterly, only after experiencing it himself, he finally understood how dangerous the process of refining the unicorn bone was, from beginning to end, he felt that he was walking on a strand of hair, neither let the hair break or fall into the abyss, this was not much more difficult than dealing with the Bodhi tree.

"The first Qilin Bone has been refined, but you still have a chance to choose whether to abandon this body like me, or continue to refine the remaining Qilin Bone. ”

Yu Xuzi looked at Li Yunsheng very solemnly.

"Go on. ”

Li Yunsheng did not hesitate.

"Good. ”

Yu Xuzi smiled and nodded.

Because of the consumption of the power of the divine soul, and because the pain caused by refining the first unicorn bone had not completely dissipated, the refining process of the second unicorn bone was even more difficult than the first.

This time, it took Li Yunsheng four full hours directly to complete the refining.

Then he had a third, which took six hours. The fourth took eight hours, and the fifth took a full twelve.

For Li Yunsheng, this is completely a competition against himself.

For every minute of time he endured, he had to endure more pain.

But he also knew that the stranger from outside the world was coming, and he had no room to avoid it.

You can put aside your own life and death, but what about the people around you?

He no longer wanted to see any relatives and friends around him, like Qiushui's brothers and sisters, being taken away in front of his eyes.

The tenacity shown by Li Yunsheng also completely impressed Yu Xuzi, who had been watching from the sidelines.

"The last one. ”

He looked at Li Yunsheng with a serious expression.

At this time, Li Yunsheng's face was as white as paper, and he looked completely dying.

"We ...... Go on. ”

Li Yunsheng nodded, then closed his eyes.

The refining process of this last unicorn bone was longer than the previous five, and aside from the fact that Li Yunsheng was already extremely weak, the meridians and blood vessels that the last unicorn bone had to fuse were more than the previous five combined.

Yu Xuzi had expected that this process would be very long, so he was not in a hurry, but just waited quietly on the side.

And this wait is three days.

Li Yunsheng, who seemed to have fallen into a long sleep, finally opened his eyes.
