After everyone opened their Dan furnace, Cheng Haoxuan began to point out their shortcomings one by one.

Of course, when the Dan furnace was opened, there were still some people refining the pills that stinked and burst into flames.

These were all prepared for Cheng Haoxuan before, but now he can only eat the bitter fruits he has grown.

Cheng Haoxuan smiled, the welcome method is really special, and there are so many things for himself.

But even so, it still needs to be taught.

Cheng Haoxuan also believed that through what happened just now, they should have understood that all means were useless in the face of absolute strength.

I should be a little more obedient, so that I don't have to be so tired.

Although there are many students who want to be funny at first, there are still some who are seriously refining.

Coming to a student, looking at the Qingxin Pill she had refined, she frowned.

"Mentor Cheng, is there any problem?" the girl asked with a frown when she saw Cheng Haoxuan.

"The pill cracked, the flames were not fierce enough, and the light focused on the surface. Cheng Haoxuan shook his head and said.

"What? wouldn't it?"

"She is the best in the sect besides Elder Chen who is the best at refining the Pure Heart Pill. ”

Everyone was surprised when they heard Cheng Haoxuan's words.

"This can't be a teacher, there is absolutely nothing wrong with my Pure Heart Pill, if you can't know it I suspect you're undermining our faith. The female student said excitedly.

Cheng Haoxuan glanced at it, and then grabbed the Pure Heart Pill.

There is nothing wrong with the surface looking smooth as jade, but in fact.

I saw Cheng Haoxuan take out the Shura Sword and slash the Pure Heart Pill with a sword.

The inside of the Qingxin Pill, which was cut in half, was all black.

I saw a large number of cracks inside, and even residual medicine residue.

"It's—it's impossible!" the girl said in surprise.

"Hmph, lie to yourself, flashy. Cheng Haoxuan sneered.

Walk away to see the next academy.

"Cheng Guru, please advise. A boy said.

He handed over the pill in his hand.

Cheng Haoxuan looked at it and sniffed it.

"Well, the color is bright and the medicinal fragrance is strong. Cheng Haoxuan nodded.

The corners of the male student's mouth rose slightly.

"But the flame is too fierce, and most of the medicinal properties of the original elixir have been burned by you, not that the bigger the fire, the better, you have to learn to control it. Cheng Haoxuan suddenly changed his words.

The student's face began to darken when he heard this, and the smile on the corner of his mouth gradually disappeared.

"Let me make an analogy, alchemy, just like baked potatoes and roasted sweet potatoes, if you have a light fire, the potatoes will definitely not be cooked, and if you are cooked on the outside and raw on the inside, if you are on heavy fire, you may be burned directly to charcoal. Cheng Haoxuan gave a simple and easy-to-understand example.

Everyone present nodded thoughtfully.

And some are disdainful, and the corners of their mouths are raised.

is like the student who showed Cheng Haoxuan his elixir.

After listening to Cheng Haoxuan's words, his fists were already clenched, and he looked at Cheng Haoxuan through gritted teeth.

"What's the matter, this classmate, do you have any questions?" asked Cheng Haoxuan, the corners of his mouth rose slightly.

"Hehe, it's nothing, I just think it's a little inappropriate to become a mentor, turning alchemy into a baked potato, I want to ask Mentor Cheng, have you always treated alchemy as a baked potato?" the boy asked with a sneer.

"That's a good question, then I want to ask, this classmate, do you know how to bake potatoes? If you can't even bake potatoes, don't do alchemy. Cheng Haoxuan smiled.

"I, of course I would! No, alchemy has nothing to do with baked potatoes!" the boy replied with a stumbling face.

Only then did he react, but it was too late, he had already caught Cheng Haoxuan's way.

Everyone knows that, of course, it's not a laugh to not be able to bake potatoes.

It's just that the boy took too long to react, and Cheng Haoxuan really answered when he asked.

"If you can't learn how to control the flames, when to control the strength of the flames, then that's all for your life. Cheng Haoxuan smiled.

There was no fear that it would hit the boy's weak heart.

How can you see a rainbow without experiencing wind and rain, and he is not his own person anyway.

Thinking of this, Cheng Haoxuan was even less concerned.

Anyway, you don't listen to me when I talk to you, I always feel that I am very powerful.

Do you think that this seven-rank alchemist came for nothing?

Past this student, Cheng Haoxuan continued to look at the next one.

It was a girl, only about fifteen or sixteen years old.

She was already trembling a little after the problems that had arisen in the previous two people.

Cheng Haoxuan turned a blind eye and looked at the spirit pill next to him.

Just one glance at Cheng Haoxuan didn't want to look at it.

I don't even think about anything.

Because the three-grade Huiling Pill refined by that girl is not ordinary.

The concentration of such a thing as an elixir is the essence, but it is the first time that Cheng Haoxuan has seen such a big fist.

How subtle the properties of this medicine are, just how to refine the Sanpin Pill.

Cheng Haoxuan was completely speechless, but the girl looked at Cheng Haoxuan expectantly and wanted to hear what Cheng Haoxuan would answer.

Business still has to be done, Cheng Haoxuan can't praise her and make her think that this refining is right.

That's not a good seedling that delayed alchemy.

Like himself, there are not many people who have alchemy.

"Ahem, classmate, you return to the elixir, there is no big problem. Cheng Haoxuan coughed twice.

The girl was happy when she heard this, but Cheng Haoxuan had to tell her the reality.

"It's just ......," Cheng Haoxuan continued.

As soon as she heard the words Cheng Haoxuan, girls knew that it was not good.

immediately put away his smile and listened to Cheng Haoxuan's speech solemnly.

"It's just that this elixir is a bit big, that, it's not easy to mouth. "Cheng Haoxuan didn't know the way.

After all, it's troublesome to explain, so it's better to look for the drawbacks.

"No, I will become a mentor, I will eat it all in a few bites, crunchy. The girl laughed.

"Well, actually, the bigger the elixir is not refined, the better. Cheng Haoxuan saw that she didn't start it, so she had to explain.

The girl looked at Cheng Haoxuan suspiciously, waiting for Cheng Haoxuan's next step.

"On the contrary, the more elixirs the better, because even if thirty or fifty elixirs are refined together, the medicinal power will not exceed the size of a mouth. Cheng Haoxuan explained.

"Therefore, refining such a large pill, it is difficult for the medicinal power to take effect if the medicinal power is not concentrated, and the pills are swallowed directly, and it is easy to absorb the medicinal power when it reaches the abdomen, otherwise it will be a waste of medicinal properties and a lot of effort to bite and eat such a large one. Cheng Haoxuan said.

"Therefore, concentration is the essence, and in the future, refining the pill should be as big as a fingernail. Cheng Haoxuan said with a smile.

But it was obviously a kind reminder, but in the eyes of the girl, it was laughing at her openly.

Cheng Haoxuan shook his head helplessly, why was it so difficult for him.

Seeing the girl staring at herself viciously, she felt very faceless, gritting her teeth, and Cheng Haoxuan didn't know what to do for a while.

It's just that the people around me should just watch the excitement and not think it's a big deal.

This is more in response to the girl's thoughts, and she feels that Cheng Haoxuan's words humiliate her in public, making everyone laugh at her.
