Zhang Yu was also stunned when he heard Xu Lie's question, especially Xu Lie's bloody chin before with a bloody scab, no beard, and a particularly young face.

"How could I have a wind spirit root, it's just a trick with flames. ”

Zhang Yu secretly wondered that Xu Lie was quite young from this point of view - this also means that Xu Lie was very young when he built the foundation and had extraordinary qualifications.

But Xu Lie's words made Zhang Yu realize that "heating the air to form the wind" was cold knowledge in his previous life, and it was definitely a treasure in this cultivation world.

It's about the spiritual root, even if it's a relatively rare knowledge of the wind spiritual root, it's definitely not a bargain anywhere.

"Seeing that Brother Xu Lie doesn't plan to absorb the big cloud frog, isn't there any hope for himself to marry Dan?"

Zhang Yu's care left and right, he made Xu Lie look confused:

"Who told you that I am the Wind Spirit Root? The Tiangang Qi on this big cloud frog is for my son. ”

The more Xu Lie said, the more he understood what Zhang Yu meant—things related to spiritual roots could never be sold cheaply, and this matter was definitely not something that Zhang Yi, an ordinary qi cultivator, could know, and Zhang Yu's knowledge must come from the old Zhang family.

Although Xu Lie took more care of Changyu before, Changyu also returned a favor.

This is not easy to tell Xu Lie.

When Xu Lie realized this signal, he paid more attention to it, he was a civil and wood spirit root, and his daughter-in-law was a waste spirit root of fire gold, and he had been worried about giving birth to a child with four spirit roots, but his son was born with a very rare wind spirit root.

Although he was less worried about his son's future, the mutation of this spiritual root made Xu Lie wonder if he was a cuckold.

Now that he heard that Zhang Yu, a monk with a fire spiritual root, could create wind, Xu Lie's pimple was a little looser, but Xu Lie's son was originally a wind and fire spiritual root, and the attributes of both spiritual roots were not too high.

Xu Lie's previous idea of cultivating his son has always been to borrow the wind from the wind and use the wind to cultivate the fire genus, but this Tiangang Qi is more conducive to the wind spiritual root, if he can change to the wind spiritual root as soon as possible, it is definitely good, but a specific idea cannot be taken out at once.

Zhang Yu's "fire and wind" gave Xu Lie a lot of hope.

Xu Lie didn't want to take advantage of it, but he still gritted his teeth and said: "This link is really important, as long as Brother Changyu is willing to tell me, the price is up to you." ”

Seeing Xu Lie's serious face, he didn't even care that the blood scab on his chin had fallen off two pieces and began to bleed, Zhang Yu also realized that this seemed to be quite important to Xu Lie!

Zhang Yu originally planned to pretend to be mysterious and raise the price, but looking at Xu Lie's solemn appearance, he didn't know how to speak for a while.

First, I really haven't thought about what kind of profoundness is "high temperature heating air makes the expanding air rise and cold air falls".

The second is what if the price is high, if Xu Lie finds it useless, if the price is low, Changyu is a little at a loss.

Zhang Yu groaned, and finally said to Xu Lie hesitantly: "I really can't evaluate the price of this, why don't you make a price first?" I think you are also a righteous gentleman, you shouldn't cheat your nephew, right?"

"This... Xu Lie was already ready to face Changyu's sky-high asking price, and he was also ready to bargain on the spot, but what he paid more attention to was whether Changyu was willing to trade.

At the level of Xu Lie's middle and late stage of foundation building, as long as the spiritual materials, spiritual plants, and spiritual objects are not too special or too high-end, they can generally get their hands on them, and as the backbone of the Chashan Sect, their income is gradually stable and safe, but at the same time, they are also more confused about the road ahead.

There are many Qi cultivation disciples, basically as long as they practice the exercises within the sect, there will always be many people who practice the same exercises, coupled with the experience of their predecessors, although there are many routes, they will not be too confused if they are ignorant.

Only when the foundation building period is reached, the number of cultivators of the same sect and the same practice has decreased sharply, and everyone has hidden secrets, although they are practicing the same exercise, their understanding is different, and there are many unnoticed omissions when refining qi and building the foundation.

Often, monks who practice the same exercise, without the guidance of the teacher, are always abused by the teacher!

The exercises are just those words, but just like the exercises "Tanggu Secret Copy" practiced by Zhang Yu, some people think that the most important thing is the "ten days in the air" Golden Crow, and the main focus of these people is on the fire vein, and the emphasis is on training and even creating the fire crow of the incarnation outside the body to move closer to the Golden Crow.

Some people focus on that, "There is a buttress, and the pillar is three hundred miles, and its leaves are like mustard." Then the focus of this kind of person is on the genus of wood.

Even thinking a little more, studying Ganyuan, Tanggu (Fusang), and poor mulberry, and building a land, the focus of cultivation is based on the legend of "those who have Ganshan, Ganshui comes out of Yan, and gives birth to Ganyuan", and moves closer to the water genus and the earth genus.

More than 1,000 people will have a thousand Hamlets in their hearts when they watch "Hamlet", and the cultivation methods of 1,000 people cultivating "Tanggu Secret Code" may also be strange.

These different emphases are not as powerful as the one that is more powerful, but the road is dangerous and supported by predecessors and experience!

Zhang Yu saw that Xu Lie didn't speak for a long time and didn't know what to say, anyway, there was no loss, Zhang Yu thought about it or broke the deadlock first, if Xu Lie really thought it was a great secret, it would not be good to kill people or something:

"Actually, it's not a big reason, as long as Uncle Shi pays more attention to himself, he will sum it up, I'll just say it, Uncle Shi, you look at it and give a price, right?"

Xu Lie was still thinking about how to make Zhang Yu speak, but Zhang Yu himself burst out, but he didn't know what to say for a while, so he could only say something in a while:

"W-is this going to work?"

Seeing Xu Lie think more and more deeply, Zhang Yu stopped Xu Lie's words in time and began to say in words that the cultivation realm could understand:

"Uncle Shi usually notices that everything else is falling when he lights the fire, but only this smoke can rise. ”

Changyu organized the language to minimize what gravitational force and other modern physics knowledge:

The reason why this smoke can rise is because the flame bakes up the air, and the air with heat rises, and the cold air in the vicinity gathers again, and this movement forms the "wind". ”

Zhang Yu just said a few words briefly and let Xu Lie think about it himself, after all, if it is too obvious, it will always involve some physical knowledge, say more and leak more, in case Xu Lie likes it, he can't sell it at a high price, if Xu Lie can't look at it, he won't spend some saliva to stop.
