When night falls again, Xu Shaotang quietly sneaks into Ye Qingshi's Alchemy room.

For the arrival of Xu Shaotang, ye Qingshi is not surprised. He just makes a "please" gesture to Xu Shaotang, and sits there quietly with his knees crossed. It seems that he doesn't intend to leave.

Looking at Xu Shaotang's surprised eyes, ye Qingshi said in a low voice: "I really want to see your alchemy skills. I'm the only alchemist here. It's too difficult for me to improve. Maybe, although I don't know how much you have mastered the alchemy, I know your attainments are not lower than mine. If you don't mind, I hope to be here It may be good for my own promotion to watch it in the classroom. "

"Whatever you want!" Xu Shaotang shrugged his shoulders and said, "but I should be here all the time tonight. Are you sure you want to sit here all night?"

Ye Qingshi nodded his head firmly and said with a smile, "don't forget, I'm also an alchemist. It's a common thing for me to sit here for a night."

"Well..."

Xu Shaotang really forgot that.

Since ye Qingshi insists on watching here, he doesn't care. Anyway, as master Liang Danqing said, the most important test of alchemy is savvy. If ye Qingshi doesn't have enough savvy, he won't have a chance to steal a teacher. Of course, if ye Qingshi can understand it, it is not a bad thing.

Xu Shaotang silently takes down his burden and takes out the elixir he secretly picked in Heifeng valley that day.

He did not rush to put the elixir into the alchemy furnace, but sat there and played with each elixir repeatedly.

Looking at Xu Shaotang's actions, ye Qingshi's face is full of doubts. Of course, he knows these kinds of elixirs. They are common elixirs, and they are also the most common elixirs he has. With these elixirs, he can only make some pills for activating blood circulation and removing blood stasis. Naturally, the price of these elixirs is very cheap.

The price is cheap, which means that there is no qualification to enter the auction house. How can the auction house sell the pills that can be bought with hundreds or even dozens of gold coins!

"What pills do you want to make?" Ye qingshiman looks at Xu Shaotang in doubt.

"Well, Yiqi pill." Xu Shaotang didn't know whether there was this kind of elixir in the world. He explained: "it's the elixir that can help the martial arts absorb the aura of heaven and earth."

Ye Qingshi looked at Xu Shaotang with astonishment: "do you want to use these elixirs to refine Yiqi Pills?"

At this moment, he suddenly began to doubt whether the young alchemist knew alchemy or not.

"What, is there a problem?" Xu Shaotang said with a smile: "although this Yiqi pill is also a low-level pill, it can help the martial arts to absorb the aura of heaven and earth, and the price should not be too low, right? By the way, in your experience, how many gold coins do you think Yiqi pill can sell? If it's too cheap, I'll consider refining other pills? "

"A Yiqi pill, with me, can sell at least 10000 gold coins, and it still has no market, because the success rate of Yiqi pill is too low!" Ye Qingshi slightly looked up at Xu Shaotang, his lips moved, and added: "the premise is that you can use these garbage elixirs to refine Yiqi Pills!"

Yes, in his eyes, there is little difference between these elixirs and garbage. If it wasn't for the huge demand of pills for promoting blood circulation and removing blood stasis, he would not bother to use these garbage elixirs.

Every alchemist hopes to make precious pills, and he is no exception.

"Ten thousand gold coins?"

Xu Shaotang's eyes suddenly lit up, which is equivalent to a low-grade spirit stone! Is a low-grade pill so valuable?

And the price of these elixirs in his hands, together, is estimated to be no more than 200 gold coins!

Sure enough, no matter which world it is, what is linked with medicine is profiteering!

While sighing, Xu Shaotang lit the fire. When the temperature in the stove reached the ideal temperature, he put the cheap elixirs into the Dan stove according to his heart.

"So you started alchemy?" Ye Qingshi looks at Xu Shaotang with astonishment.

Xu Shaotang nodded and asked, "what else is that?"

"No need for cinnabar?"

Ye Qingshi is now basically sure that Xu Shaotang understands alchemy, but only in theory. It is estimated that this is his first alchemy, isn't it?

"Well, what is cinnabar?" Xu Shaotang looks at Ye Qingshi suspiciously. Liang Danqing doesn't tell him that he still needs the red sand for alchemy. He doesn't know what the red sand is.

Ye Qingshi looked at Xu Shaotang with a wry smile. He slowly stood up and went to a jar beside him. He grabbed a small handful of crystal clear coarse sand from it and handed it to Xu Shaotang. He said slowly: "this is cinnabar. It's a kind of stone containing the aura of heaven and earth. However, compared with the spirit stone, the aura it contains is insignificant, but it's indispensable for alchemy Less introduction can also make the elixir in the elixir furnace more evenly heated, and make the rate of elixir formation higher. "

Looking at the cinnabar in Ye Qingshi's hand, Xu Shaotang gently grasps his head. He really hasn't heard of it. He is thinking about whether to add it in.However, after thinking about it, he finally gave up. Maybe the alchemy in this world is different from that taught by Liang Danqing. He still made it in his own way. With this bottle of alchemy that ye Qingshi had been refining for many years, he still had some confidence in the rate of success.

"It's OK. I'll just refine it like this. When I can't, I'll try the effect of this cinnabar." Xu Shaotang said with a smile.

"So it is Ye Qingshi showed an imperceptible sneer at the corner of his mouth and said faintly: "anyway, these elixirs are also very cheap."

In his opinion, Xu Shaotang, let alone refining Yiqi Pills from these garbage elixirs, even refining the lowest level pills that can promote blood circulation and remove blood stasis is impossible. Without the introduction of cinnabar, he will only see a furnace of residues when he starts the furnace!

"I'm a little sleepy all of a sudden." Ye Qingshi put the cinnabar back into the jar, yawned and said, "I won't disturb you here. You can refine it slowly. I'll go to sleep."

He already knows the result, so there's no need to look at it any more. If it wasn't for Xu Shaotang's unfathomable strength, maybe he has started to drive people out now, and let a fake alchemist who doesn't know anything use his own alchemy furnace. It's really an insult to his precious alchemy furnace!

Xu Shaotang had already guessed what ye Qingshi thought in his heart. He nodded with a smile and said, "you go to have a rest. I'll leave after refining. Don't worry, I won't touch anything here."

Ye Qingshi said: "I believe this. If you want to move these things, they will be gone long ago."
