Zhao Chiyun took the pill and looked at it casually.

To be honest, although he didn't look down on Shen Tongyu's character, he didn't think that Chu Chennan's alchemy could surpass Shen Tongyu.

After all, the former, but the Dan Dao genius, known as the No. 1 Alchemist of the Inner Gate, has controlled the Dan Pavilions for several years, and no one dares to challenge.

But Chu Chennan is just a down-and-out kid, and there have never been rumors before that he has Dan Dao talent.

So in Zhao Chiyun's view, this challenge was actually doomed from the beginning.

"To be honest, the old man actually hopes that Chu Chennan won, but it's a pity...... Huh?"

Zhao Chiyun was muttering in his heart, but he suddenly looked stunned, and his eyes gradually became incredible.

Shen Tongyu didn't see the change in Zhao Chiyun, and was still sneering: "Boy, I think you should admit defeat by yourself, anyway, everyone can guess the result, you take the initiative to admit defeat, at least you can save some face." ”

Chu Chennan glanced at him lightly and did not speak.

"What, still not convinced?"

Zhao Chiyun sneered and shook his head: "It seems that you really don't cry when you don't see the coffin, or not, since you don't know what to do, then the pavilion master will soon let you know that this kind of thing is not something that anyone can do well." ”

He snorted and looked up, but suddenly found that everyone around him was staring at Zhao Chiyun in a daze, as if something was wrong?

So he hurriedly turned around, and finally saw Zhao Chiyun's face full of solemnity, and he actually stared at the pill in his hand.

"What's the matter, is it this kid's elixir, is there something wrong?"

A sense of foreboding suddenly rose in his heart.

At this time, Zhao Chiyun finally raised his head and asked, "What kind of pill are you, why have I never seen it?"

"This is the Jiuqu Tongxin Pill, I saw it from an ancient book, and that ancient book is not widely circulated, so it is normal that the elder has not seen it. ”

Chu Chennan smiled lightly.

In fact, the Jiuqu Tongxin Pill is the elixir recorded in the "Baopu Dan Sutra", and it is of course impossible for people in this world to see it.

"Jiuqu Macaranda, good name!"

Zhao Chiyun was a little excited: "Little guy, what is the effect of this elixir, I feel that the medicinal power in it seems to have the effect of calming the mind?"

"The elder is really discerning, this is an elixir that can calm the mind and calm the demons, and it can allow the martial artist to get rid of the shackles in his heart and cultivate to a great progress. ”

Chu Chennan explained: "When refining this elixir, it is necessary to form nine subtle pipes inside, just like a human blood vessel, the links are coiled all over the entire pill, and a miniature meditation array is formed, which can increase the efficacy of the pill dozens of times. ”

"Actually forming a formation in the pill is simply a miracle. ”

Zhao Chiyun was like looking at a work of art, holding five Jiuqu Tongxin Pills, looking at them carefully, and also trying to infuse them with true qi to explore the nine pipeline formations inside.

At this moment, even if he is a fool, he can see that the Nine Qu Synax Pill is extraordinary, otherwise how could Zhao Chiyun, who is a mid-grade alchemist at the ground level, be so amazed and excited?

But Shen Tongyu was unconvinced.

His face was gloomy, and he snorted: "Even if the internal formation formation is good, it doesn't mean that the grade of the pill is high, Elder Zhao don't waste time, let's announce the result, I don't believe that this kid's pill can be compared to me!"

"It's true that it can't be compared, and it can be said that it's a world of difference, but it's not that he's worse than you, it's that you're inferior to him!"

Zhao Chiyun sneered: "According to my judgment, the grade of the Jiuqu Tongxin Pill refined by Chu Chennan far exceeds the Xuan-level superlative, and the level of medicinal power it contains is definitely comparable to the ground-level medium-grade pill!"

Earth...... Prefecture-level medium grade?

In an instant, there was a dead silence on the scene, and everyone was stunned!

One after another unbelievable gazes were all fixed on Chu Chennan's body.

Being able to refine a ground-level mid-grade elixir, doesn't it mean that Chu Chennan is already a ground-level mid-grade alchemist?

But how old is he, not yet twenty?

A boy who is less than twenty years old, Dan Dao attainments have actually reached such a level!

This...... It's hell off!

You must know that even Zhao Chiyun is only a mid-grade prefecture-level product, and his age has long exceeded 100 years old.

"Impossible!"

Shen Tongyu suddenly shouted: "He is much younger than me, how can he surpass me in Dan Dao attainments?" Elder Zhao, you are not trying to favor him, you are deliberately talking nonsense, I don't believe that this kid can refine a ground-level mid-grade pill!"

"Bold!"

Zhao Chiyun shouted loudly: "Shen Tongyu, you actually dare to slander the elders, aren't you afraid of the punishment of the sect's precepts?"

"I ......"

Shen Tongyu froze for a moment.

He patronized and questioned, but he forgot that the Extreme Dao Martial Sect was highly hierarchical, and it was a serious crime to slander the elders as a disciple.

But once the words have been spoken, there is no way to take them back.

Now his only hope is that Chu Chennan's Jiuqu Tongxin Pill cannot reach the level of the prefecture-level mid-grade at all.

In this way, the crime of slander cannot be confirmed, and it can only be regarded as reasonable questioning, and it will not be punished by the precepts.

So he gritted his teeth and said forcibly: "Elder Zhao's atonement, it's really too hard to believe this matter, after all, how can a teenager in his teens become a mid-grade alchemist at the prefecture level, I hope the elder can prove it!"

"Don't believe it, okay, then I'll open the seal of the pill and let you see it clearly!"

After Zhao Chiyun finished sneering, a stream of true qi poured out from his palm, and it was directly submerged into the pill.

After the refining of the elixir is completed, the alchemist will place a seal on the surface to protect the medicinal power from loss.

And once the seal is opened, the external manifestation of the elixir will be revealed.

Normally, different grades of pills will have different external manifestations.

For example, the lowest-grade ordinary pills will exude a strong bitter and astringent medicinal taste, while the yellow-grade high-grade elixirs will disappear and instead exude a faint fragrance.

Another example is the Xuan-level low-grade elixir, in addition to the overflowing fragrance, it will also emit a faint energy fluctuation, while the Xuan-level middle-grade elixir, the energy fluctuations it emits, can already make the air ripple slightly.

And like the Xuan-level supreme elixir refined by Shen Tongyu, it will not only produce clear air ripples, but even make a sound similar to the wind howling.

These external manifestations are the most intuitive criteria for judging the grade of Dan medicine.

As Zhao Chiyun opened the seal, he saw that the five pills in his palm suddenly burst out with amazing energy.

These energies react with the air, manifesting visions of wind, torrential rain, and sometimes plants and beasts.

Being able to image the void and have a clear image is exactly the external manifestation that only the earth-level mid-grade pill can have.

Chu Chennan's Jiuqu Tongxin Dan has really reached the middle grade of the prefecture level!
