Qing Yu was very sure in his heart that the noble man in front of him must have come to buy medicine, since they settled here in Qujiangfang, there are countless dignitaries and dignitaries who ask for aphrodisiacs from the master every day, and even the old threshold in front of the hospital is a little tattered.

Yesterday, a gray-haired old man walked into them tremblingly, and he didn't admit that he was buying medicine for himself with a shy face, but when he said that the Jade Divine Pill was handed over to the old man, the excitement in his eyes even made him almost startled.

I'm afraid that if this old man eats like this, he will never get up again. Fortunately, he is also a clever man, so let the old man dissolve the Jade God Pill in warm water by a quarter each time, and the effect of the medicine will suddenly decrease a lot, and it will not reach the level of Optimus Prime, at most it can be regarded as a light twist and wipe.

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

Gold and silver were scarce in the Tang Dynasty, and copper coins and silk silk were generally used as currency. But it's not that gold and silver are not money, it's just that there is some trouble in exchanging, and you have to go to the jewelry store in the East Market to exchange money.

That piece of gold ingot weighed about three taels, and the money exchanged for it was forty-five and three yuan, which was enough to buy some alchemy materials and live a good life for a few days.

Yesterday afternoon, the master's alchemy furnace exploded again, and this was the twenty-third time this month......

There weren't many big customers like yesterday, but the Emperor Taishang in front of him made Qing Yu very excited, so he coughed, approached the Emperor Taishang, and said: "This Jade Divine Pill, although it is a mortal product, but the nobles think about it, this is the Dan prescription taught by the goddess herself, and you will keep it on the bed....... Dragons and tigers.

And a five-run penny, what a bargain! ”、

After speaking, he took out a vial of mutton fat white jade from between his sleeves, and poured out two light blue pills the size of pigeon eggs, which were fragrant.

The old face of the Emperor twitched. It's unnatural. Ordinary pills, how can they be so fragrant, there must be some spices added, can that thing be eaten? And this crystal blue skin, no matter how you look at it, it looks like it has been plated with a layer of chemicals, and if you eat it, you may poison people.

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

"Qing Yu, you misunderstood, I came to find Daochang Sun this time, not to ask for medicine, but to ......" Li Yuan was stunned for a moment, he didn't know how to tell Qing Yu.

He thought for a while, coughed dryly, and said, "I came here this time to ...... See for yourself how you do alchemy, I just want to stand aside and watch. ”

Qing Yu suddenly understood, and the eyes that looked at the Emperor Taishang were also suddenly intriguing. looks like he is in his fifties, but he doesn't ask for an aphrodisiac, but he wants to see alchemy, so the answer naturally comes out, "Do you want to live forever?" ”

After that, his eyes looked at the Emperor Taishang more and more ambiguously, this is a like-minded customer!

Alchemy is not something that ordinary people can play, Sun Simiao casually sees a doctor for a large family, and the medical fees charged may allow ordinary people to live for a lifetime.

But Sun Simiao's yard in Qujiangfang is rented, which is not only small, but also very broken.

The reason is naturally that the main page of alchemy costs too much money, and the materials for alchemy alone are worth a lot of money, not to mention that Sun Simiao's Dan furnace has exploded a lot of times.......

And seeking the elixir of immortality will naturally cost a lot more, if there is the gold lord in front of him to take care of it, then he Qingyu will not have to recommend aphrodisiacs pitifully to take business.

"Your Excellency, please come with me."

Qing Yu made a mockery of the Emperor Taishang, and then led Xiaodao Tong Qingxin with one hand, turned left and right in the corridor and walked to a small courtyard.

On the south side of the courtyard is a pile of firewood piled up against the wall, and on the north side is a slightly simple thatched house. The courtyard was paved with a layer of bluestone, but before it rained, it corroded into potholes, and there were sewage of different colors in it.

"This is the place of the Poor Dao Alchemy." Qing Yu forcefully pushed open the closed wooden door of the thatched house, only to hear a creak, and after the wooden door opened, the inside was unobstructed.

The alchemy vessel in the middle is somewhat similar to the Taishang Laojun Bagua Furnace that Li Yuan watched on TV, only slightly shabby, but there are exquisite reliefs on its surface......

After careful observation, Li Yuan found that the alchemy furnace was indeed a little similar to the retort in the dining room, but the lines at the junction were more supple, and on the right side of the retort lid was a slightly smaller cooling utensil, which contained cold water, while in the alchemy furnace, there was a copper channel with a curved neck extending along the bottom to the top, clinging to a small vessel as large as an inkstone.......

"Please borrow this strong man's saber." Qing Yu walked up to Su Meng's side, with a faint smile on the corner of his mouth.

Su Meng was about to refuse, but when he saw the eyes of the Emperor Taishang, he reluctantly pulled out the saber in the scabbard and handed it to Qing Yu.

"Have you ever seen a golden sword?" As Qing Yu spoke, he dipped his saber into a pale blue sink. The surface of the sink suddenly began to boil, and within a few moments the part of the saber that had been immersed in the sink turned golden, and it seemed that there really was a mysterious power.

"This is immortal magic!" The Qingxin Xiaodao Tong triumphantly fished out the saber from the sink and returned it to Su Meng.

Su Meng and several other guards were instantly impressed by the Qing Yu in front of them, and even the effectiveness of the previous Jade Divine Pill was believed in seven or eight points, if it weren't for the fact that the Jade Divine Pill was too expensive, they would even want to ask for a few.

But Li Yuan twitched his old face, isn't it just a simple chemical reaction? It seems to be called electroplating, and the light blue liquid should be copper sulfate, and according to the chemical displacement reaction, a layer of copper is plated on it.

This is immortality?

No, it's teasing him!

As a modern person, the Emperor Taishang looked at Qing Yu's self-congratulatory mode, not to mention how embarrassing it was, the key Qing Yu and Qing Xin were all ordinary people, how could the scum know how powerful our immortal skills were.......

Then Su Meng and the others looked adoring.

However, the Emperor Taishang has not stepped forward so irrationally to interrupt them, although he knows what science is, but if he does this, it will be smashing the job of the Taoist priest, and it is easy to provoke public anger! What's more, in later generations when science and technology were so advanced, there were still many religious elements, and there were even as many as 10,000 ascetics in Zhongnan Mountain.

Compared with science, the people believe that there are immortals in the underworld, and religious people such as Taoist priests are the spokesmen of the immortals.

So, this matter is completely unnecessary.

After turning the iron knife into a golden knife, Qing Yu looked mysterious again, took the dansha milled by Qingxin and poured it into the alchemy furnace, then closed the retort lid, and said in a deep voice: "Nobleman, this is the first step of alchemy, steaming dansha!" ”

The mercury in dansha has always been an indispensable neutralizer for many pills.

Xiao Daotong tiptoed from the courtyard to bring some firewood, put it into the alchemy furnace, and then held a fan about the size of him and kept fanning, and after a while, he was robbed by the smoke and coughed.

And in a room in another part of this place.

Sun Simiao rubbed his eyes, got up from the bed, opened the window, looked at the sky, and said with a sigh: "I blew up a Dan furnace at night, Lao Dao has almost mastered the materials of the explosion, but unfortunately I just put the materials into the alchemy furnace, I can't stand the sleepiness, I never thought it was already the time (10:00).

This is the last alchemy furnace......."
