Ye Xiaokai took out a plain cyan jade bottle from his arms, which was the Baihui Dan given by Bailixi two days ago, when he cleaned up those demon beasts, as a reward, Bailixi gave him five Baihui Dan, in addition, as Hang Daiyu's guide, he accepted the guide fee of two bottles of Baihui Dan, which can be described as a pit person, and turned around and left Bailixi and Bailifeng father and son, but think about it, Hang Daiyu seems to be worth the price, her identity is not ordinary.

The remaining two jade bottles each had six white pills, one more than this bottle, Ye Xiaokai guessed that six was the real original number of each bottle, and Bailixi must have deliberately tricked him.

He took out the pill and put it in the palm of his hand, the pill was white, round, slippery, and when he looked closely, there were very fine lines around him, and he exuded a refreshing fragrance, standing in front of it, it would also make people feel inexplicably comfortable mentally, and it was very strange.

Ye Xiaokai used the technique to adjust the state, he had never cultivated the vitality, and this pill was also known as the Baihui Pill, which could improve the vitality cultivation of Dao cultivation, so he didn't know what kind of effect it would have on him, but he definitely wouldn't have no effect, out of some kind of intuition.

He picked up this elixir and stuffed it into his mouth, and under the effect of the Ice and Fire Heavy Heaven Technique, the elixir suddenly melted in his mouth, becoming a wave of pure and surging energy, surging towards Ye Xiaokai's limbs, however, this energy actually hit a wall and could not be absorbed by him, and every cell was trying its best to reject this energy that invaded later!

In the end, it turned into a roaring dragon in Ye Xiaokai's body, wandering around, trying to break through, but all failed.

"The Ice and Fire Heavy Heaven Technique is only a mortal Dao level exercise, and it can't control the vitality to follow the cultivation path, even if it is the Ice and Fire Heavy Heaven Technique after the mutation, it can't work!" Ye Xiaokai quickly figured out the reason, because he was about to reach the peak of mortal humanity, so he needed to change the exercises! But after changing the exercises, he might be able to control these Yuan Qi to operate, but could he really break through to the Baihui Dao?

Ye Xiaokai didn't know, he had a lot of doubts in his heart, for example, when he was in the Curling Jade Realm, the swordsman named Wu Fengling told him very clearly that mortal humanity was the limit of his cultivation, and he would not be able to break through to a higher level, Ye Xiaokai didn't care about this before, but now that he is about to reach the peak of mortal humanity, it is finally time to consider these issues.

He always felt that Wu Fengling didn't lie to him, but how could Wu Fengling know about the problem that he didn't even know?

"If it were true, this man would be terrible, he knows myself better than I do. Ye Xiaokai's face was serious, this person always appeared by his side in a very timely manner before, and appeared just to help him, and always said some strange things to remind himself, he felt that Wu Fengling must have a plan, as for why he didn't take advantage of his weakest strength now and hurry up, he couldn't figure it out.

"No matter what, this person needs to be cautious when he meets him in the future!" Ye Xiaokai secretly labeled Wu Fengling as a danger to alert himself.

"Hmph, I don't believe there is no way to solve this mass of vitality in the body!"

There are always more ways than difficulties, Ye Xiaokai did not panic, he tried repeatedly, running the trick over and over again, and carefully felt the changes in the vitality in his body.

"Touch the analogy!" Ye Xiaokai performed this strange thinking trick, wanting to quickly capture some traces to follow, his mind flashed, and he threw out the question in time, and launched a series of thoughts, analysis, and determination.

Why did the Ice and Fire Heavy Heaven Technique produce a mutation in his body? It was because his body was mysterious, and he finally adjusted the original version to the most suitable way for his cultivation; what about the root power of the change? The mysterious power that came from his body! Ye Xiaokai's mind was thinking quickly, and his mind was highly concentrated.

Now that the aura has appeared, and it cannot be digested and absorbed, can the Ice and Fire Heavy Heaven Recipe be changed again? He threw out a new question, quickly analyzed, and quickly determined the answer, naturally he could! This kind of technique would work and change in the way that was most beneficial to him!

After learning the answer, Ye Xiaokai devoted himself wholeheartedly, fighting for his fate to turn the Ice and Fire Heavy Heaven Formula, and finally, when he reached the hundredth Zhou Tian, he found that the route of the formula had changed automatically, and there were many small meridian branch routes, and this simple change obviously made the vitality in his body begin to decrease!

"It really works!" Ye Xiaokai was overjoyed, he continued to run the technique, and at the same time observed the route and destination of those Yuan Qi that were led away, and found a result, that is, there were many more branches in the route, but in the end, they all led to the thumb joint!

As the route of the Ice and Fire Heavy Heaven Technique was revised again, he found that the majestic pure vitality in his body actually began to move towards his knuckles little by little, of course, it could only be transported here, and the cells in all parts of his body still couldn't enter!

He was overjoyed, threw himself into it, and began to carefully condense these vital energies, so that they became muscle patterns and condensed in the thumb joint of his right hand!

Two hours passed, and finally the new route of the Ice and Fire Heavy Heaven Recipe tended to stabilize, and the speed of absorbing the vitality became faster and faster, and all the vitality contained in Baihui Dan was absorbed cleanly!

"Whew!"

Ye Xiaokai opened his eyes and exhaled a breath of turbidity, this time the absorption time was a bit long, but it was mainly because he spent most of his time perfecting the route of the Ice and Fire Heavy Heaven Technique, and now that he has completely perfected it, it will save a lot of trouble in the future.

He looked down at the muscle lines at the thumb joints and was amazed!

This time, there was one more color of the muscle lines, and on top of the original blue muscle lines at the bottom layer, a third of the white muscle lines appeared, superimposed on them, making a small section of his thumb look like white jade, glowing with oil.

"It seems to have succeeded!" Although there is still a third of the muscle pattern that has not been filled, Ye Xiaokai is also satisfied, a Baihui Pill has achieved this earth-shattering effect, I don't know what it will be like if there is another one? Thinking of this, he did not hesitate, took out a Baihui Pill again, swallowed it, and then ran the Ice and Fire Heavy Heaven Technique, and continued to refine.

However, half an hour later, he was disappointed, although the energy of this Baihui Pill was also absorbed by him, it was still only in the second layer of white muscle lines, and, looking at the two layers of muscle lines, he frowned, he always felt that he seemed to think of something, but he couldn't think of anything for a while.

"Forget it, condensing two-thirds is already a very big improvement. Ye Xiaokai is not in a hurry, he plans to continue to condense this tenth muscle pattern next, and at the same time refine some characters in the whole book of the spell world, these two seem to be not simple tasks, for example, some basic characters are very mysterious and obscure, Ye Xiaokai needs to ponder for a long time before he can try it correctly!
