Cen Shan's heartbeat suddenly became unsteady, and he suddenly felt a little afraid.

This Su Su had such brilliance when he was a teenager, so when he grew up to his age, what kind of powerful figure should he be?

For the first time, Cen Shan deeply regretted that the incident of stepping on the badge that day was too impulsive, and that incident almost became an unbreakable knot between the two!

Taking a deep breath, Cen Shan closed his eyes and opened them again, this time without a trace of remorse in his eyes.

He had already made up some kind of determination.

"This problem of yours is very tricky, Zhihua Dan often has an unstable bottom fire during refining, and many Dan masters have repeatedly looked for reasons to improve it, but in the end there is no solution. As for the reason, many people also speculated, and the most positive explanation was that Ling Hanlu had some kind of change in the refining process, which caused the furnace temperature to be too low. ”

Cen Shan said slowly.

Satsuki's eyes lit up.

Zhihua Dan is a Xuan-level elixir, although she herself has not refined, but she has seen her sister refining, indeed as the master said, the fire will be very unstable during the refining process of the elixir, which undoubtedly increases the difficulty of refining, and my sister is also very distressed about this.

Although she didn't know why, she knew that the question asked by the master would not be so simple, if Cen Shan's answer was like this, then he would definitely lose!

If he answers incorrectly, then even if Master doesn't answer his next question, Master will win today.

However, after all, Cen Shan was a heaven-level Dan Master, and he was also the dean of the Pharmacist Branch of the Northern Netherworld Academy, would he give such an answer?

"I used to think this was the explanation, but then I realized that there was one thing that everyone had overlooked. In Zhihuadan's prescription, only Ling Hanlu was an ice attribute, so they thought about it, thinking that it would be the cause of Ling Hanlu, but in fact it was not, its root lay in Wen Zhaohua. ”

Warm flowers?

Xiao Yue was surprised and dazed, the nature of Wen Zhaohua is mild, how can it have anything to do with it?

There are not a few people who have the same doubts as her, and some people ask in surprise.

"Why Wen Zhaohua? It has to do with its characteristics. Cen Shan seemed to smile, "Although Wen Zhaohua is warm, but in fact it grows in extremely hot places, if there is no stimulation, then it is indeed a peaceful attribute, but when there is something with low temperature and its stimulation, it will stimulate the explosive side, only the coldness of Ling Hanlu will not cause the flint abnormality, but when it blends with Wen Zhaohua......"

When they merge, the two collide together, and there is a change in the furnace, and when the contradiction intensifies, it will affect the flint under the furnace.

It turned out to be this reason.

Xiao Yue's face was stunned, but at the same time, she frowned, and subconsciously looked at the master.

If this answer is correct, isn't it......

Su Caiyin raised her eyebrows slightly, "Dean Cen is really knowledgeable, your answer is right." ”

Cen Shan smiled lightly, although he was one question behind, but he seemed to be confident, and he did not show any panic.

"You're done, then it's time for me to ask this last question."

"Please." Su Caiyin nodded.

"My last question is medicine."

Cen Shan said, and took out a palm-sized translucent bottle from his sleeve, which contained some dark green liquid, which looked very thick, both in color and texture, which made people who saw it feel a little weird.
