Qingyu was very sure that the noble man in front of him must have come to buy medicine. Since they settled in Qujiangfang, there have been countless great officials who have sought aphrodisiacs from their masters every day, and even the old threshold in front of the yard has been a little bit broken.

Yesterday, an old man with white hair walked into them tremblingly, and with a shameless face, he refused to admit that he was buying medicine for himself. But when he said that the Jade God Pill was handed over to the old man, the excitement in his eyes was almost shocked.

I was afraid that this old man would never get up again after eating it. Fortunately, he was also a clever man. He asked the old man to melt the Jade God Pill in warm water to one quarter of the effect of the medicine suddenly decreased a lot, not reaching the level of Optimus Prime. At most, it was a light twist and wiping and re-picking.

But the money given by the old man was a gold ingot!

The Tang Dynasty was scarce with gold and silver, and copper coins and silk were generally used as currency. But it was not that gold and silver were not money, but it was a bit troublesome to exchange it, and they had to go to the jewelry store in Dongshi to exchange for money.

The gold ingot is about three taels, and the money I exchanged is forty-five silos and three cents, which is enough to buy some alchemy materials and live a good life for a few days.

Yesterday afternoon, the master's alchemy furnace exploded again. This is the 23rd time this month...

There were not many great customers like yesterday, but the Supreme Emperor in front of him made Qingyu very excited. He coughed, approached the Supreme Emperor, and said, "Although this jade god pill is an ordinary quality, but think about it, this is a pill recipe taught by the goddess himself, keeping you on the bed... Dragon spirit and tiger fierceness.

And a five-square-month money is so cost-effective!",

After saying that, he took out a small bottle of white jade mutton fat from his sleeves and poured out two light blue pills the size of a pigeon egg, which was fragrant.

The old emperor's face was so unnatural. Ordinary pills are not so fragrant. They must have added some spices. Can that thing be eaten? Moreover, the crystal-like light blue skin looks like it seems to have a layer of chemicals plated, and it may poison people if eaten.

He couldn't help but wonder how Sun Simiao lived to be eighty years old?

"Qingyu, you misunderstood. I came to find Taoist Master Sun this time, not to ask for medicine, but to think..." Li Yuan was stunned for a moment. He didn't know how to tell Qingyu.

He thought for a while, coughed dryly, and said, "I came here this time to... see how you refine the alchemy for yourself, just to stand aside and watch."

Qingyu immediately understood, and the look of looking at the Supreme Emperor suddenly became intriguing. He looked in his fifties, but he didn't seek aphrodisiacs, but he wanted to see alchemy. Then the answer came naturally, "Does the noble man want to seek immortality?"

After saying that, his eyes looked at the Supreme Emperor and his eyes became more and more ambiguous. This was a like-minded customer!

Alchemy is not something that ordinary people can play. Sun Simiao can treat a wealthy family with a medical expenses and the medical expenses collected may allow ordinary people to live their entire lives.

But Sun Simiao rented the yard in Qujiangfang, which was not only small, but also very broken.

The reason is naturally that the homepage of alchemy consumes too much money. The materials for alchemy alone are valuable, not to mention that Sun Simiao's alchemy furnace explodes a lot...

If you have the care of the elixir of immortality, then Qingyu won’t have to recommend aphrodisiacs to take on business.

"Please come with me, nobleman."

Qingyu bowed to the Supreme Emperor, then led the Taoist Tong Qingxin with one hand, and turned left and right in the corridor to a small yard.

Layers of firewood were piled up against the wall on the south side of the yard, and a slightly simple thatched hut was on the north side. There was a layer of bluestone in the courtyard, but before it rained, it was corroded and bumpy, with different colors of sewage inside.

"This is where I can refine my alchemy." Qingyu pushed open the closed wooden door of the thatched hut with force, and heard a creaking sound. After the wooden door opened, there was no clear view inside.

The alchemy vessel in the middle is a bit similar to the Taishang Laojun Bagua Furnace that Li Yuan watched on TV. It was a little bit worn, but there were exquisite reliefs on its surface...

After careful observation, Li Yuan found that the alchemy furnace was indeed a bit similar to the steamer in the kitchen, but the lines at the junction were more smooth. On the right side of the steamer lid was a slightly smaller cooling utensil with cold water in it. In the alchemy furnace, a copper groove with a curved neck extended along the bottom to the top, close to a small vessel as big as an inkstone......

"Please borrow this brave man's sword." Qing Yu walked to Su Meng with a faint smile on the corner of his mouth.

Su Meng was about to refuse, but when he saw the look of the Supreme Emperor, he reluctantly pulled out the sword from the scabbard and handed it to Qingyu.

"Have you ever seen a golden sword?" Qing Yu said as he dipped his sword into a light blue sink. The surface of the sink suddenly began to boil. In less than a moment, the part of the sword immersed in the sink turned golden, and it seemed that there was really a mysterious force.

"This is the magic!" The Qingxin Taoist boy proudly took out the sword from the sink and returned it to Su Meng again.

Su Meng and several other guards instantly looked at Qing Yu in front of him, and even believed in the effectiveness of the Jade God Pill before. If the Jade God Pill was not too expensive, they would have even wanted to ask for a few.

But Li Yuan's old face was thrusting. Isn't it just a simple chemical reaction? It seems to be called electroplating. The light blue liquid should be copper sulfate. According to the chemical replacement reaction, a layer of copper was plated on it.

Is this the magic?

No, this is teasing him!

As a modern person, the Supreme Emperor looked at Qingyu's self-satisfaction model, not to mention how awkward it was. The key is that Qingyu and Qingxin are both ordinary people. How can the slag know how powerful our immortal skills are...

Then Su Meng and the others looked admiring.

However, the Supreme Emperor did not come forward so irrationally to interrupt them. Although he knew what science was, if he did this, it would be a waste of the Taoist priests' jobs, which would easily arouse public anger! What's more, in the later generations with such developed science and technology, there were still many religious elements, and there were even as many as ten thousand monks in Zhongnan Mountain.

Compared to science, people believe more that there are immortals and gods in the dark, and religious figures such as Taoists are the spokespersons of immortals and gods.

Therefore, this matter is completely unnecessary.

After making the iron knife turned into a golden knife, Qingyu looked mysterious again. He took the cinnabar grinded by Qingxin and poured it into the alchemy furnace, then closed the cover of the steamer, and said in a deep voice: "Neighbor, this is the first step in alchemy, steaming cinnabar!"

Mercury in cinnabar has always been an indispensable neutralizer for a variety of elixirs.

The little Taoist boy tiptoed to bring some firewood from the courtyard and put it into the alchemy furnace. Then he kept slapping the palm fan about the same size as his body. After a while, he was snatched by the smoke and coughed.

And another room here.

Sun Simiao rubbed his eyes, got up from the bed, opened the window, looked at the sky, and sighed and said, "I exploded a elixir furnace last night. The old Taoist almost mastered the explosive material. Unfortunately, I just put the material into the alchemy furnace, so I couldn't stand the sleepiness. I never thought it was Si Shi (10:00).

This time it is the last alchemy furnace....”
