Before Jiang Cheng could do anything, someone suddenly shouted.

"I believe headmaster Jiang is the real eight grade emperor Dan teacher!"

The only one in the field who definitely thinks so is the emperor Ryukyu yuan.

He believes that Jiang Cheng is omnipotent.

City elder brother patted him on the shoulder with great comfort.

"You still have ears and eyes!"

The crowd was quite speechless, and they listened to whatever words were good to hear.

"By the way, do you have any questions about alchemy?"

Jiang Cheng now looks at Ryukyu yuan very pleasing to the eye. After all, this is his only loyal support in the audience.

So he, who has always been too lazy to point out others, also made a rare kindness.

Hearing what he said, Taiheng and alkyne Ling couldn't bear to witness it.

Boss, if you cheat, you'll pass.

We all pretend we don't know.

You still have to take out your alchemy attainments that are not even half a bucket of water. How can we respect you next?

Ryukyu was overjoyed.

Quickly Gong Sheng asked for advice: "when I refine the seven product green frost dense pill, every time I am about to become a pill, the pill array will become unstable and the failure rate is very high..."

Hearing this question, everyone was speechless.

"Ryukyu, what are you asking?"

Taiheng Taoist priest looked unhappy and said, "the Bi frost dense pill itself is very difficult to refine. Its low success rate is also common sense. This is a recognized universal law. How can there be a solution?"

"Yes!"

The supreme alkyne spirit also stared at him: "you give leader Jiang a question that has no answer at all. Doesn't it embarrass him..."

Before he finished, Jiang Cheng interrupted directly.

"This is simple!"

He smiled: "the instability of the Dan array is due to the conflict between ruyiluan sand, Seven Sacred wood tendon stone and Tianji flame bamboo."

"Ah?"

Taiheng and Zhenling were stunned.

Can he really casually say seven or eight main materials of Bi Shuang Yinyun Dan?

It seems that he really knows a lot about alchemy.

And the Annie Yi on one side was even more surprised.

She didn't believe Jiang Cheng could refine pills.

But with this sentence, this person is by no means a layman of Dandao.

Before Liuyuan spoke, Taiheng couldn't help frowning.

"As far as I know, ruyiwang sand itself has the nature of harmony and can be perfectly integrated with most materials. How can there be conflict?"

"You only know one thing and you don't know the other. After the Seven Sacred wood tendon stone and Tianji flame bamboo are combined, there will be variation, and ruyiwang sand will conflict with the product after variation..."

Jiang Cheng talked for a few minutes.

Within a few minutes, he collected information from others, and the characteristics and change processes of dozens of materials were all at his fingertips.

The faces of Taiheng Taoist priest and alkyne spirit Taoist priest gradually changed.

Sometimes suddenly, sometimes at a loss.

Suddenly, it was because they realized something.

It's because of many things that people who have been refining pills for so many years have never thought about, let alone achieved.

In the end, the expressions of hundreds of Di Dan masters present had all turned into shock.

Taiheng Taoist priest no longer thinks Jiang Cheng cheated before.

Although he is a master of eight grade imperial Dan, and this Bi Shuang Yinyun Dan is only seven grades, Jiang Cheng has revealed many profound knowledge he has never heard of in a few words.

It was not until Jiang Cheng stopped and other people present were thoughtful that he respectfully asked for advice.

"Do you have a way to solve this problem?"

"Of course."

Jiang Cheng smiled easily.

"Just put
