"This is Zeng Qing. Well, it's actually copper sulfate, but the name Zeng Qing is much better than those chemical names for foreigners. ”

Holding a small chisel to chisel around, early this morning, Xie Xiaoman was driven into the valley again.

But this time, Guo Pu didn't just let her get rid of the demon, but stuffed a few medicinal stones into her hand and asked her to come back with some medicinal materials for alchemy.

"Really." Xie Xiaoman pursed his lips dissatisfied, and the chisel in his hand smashed on the stone as if venting his anger, "Dead Guo Pu, you know how to arrange work for others, and you either drink or pick up girls every day, hum!" Guys who sit back and enjoy it! The capitalists of the enclosure movement! ”

said that he wanted to teach himself alchemy, but he was kicked into the valley and picked up medicine. The words of people like Guo Pu really can't be trusted.

I don't know if this toss is to teach myself something, or simply because he Guo Pu is refining the pill.

But fortunately, Xie Xiaoman was originally very interested in alchemy. Doing experiments, who is most looking forward to physical education and laboratory classes when they go to school? Alchemy is similar to a chemical experiment, except that the test tube has been replaced with a large alchemy furnace, and the alcohol lamp has been replaced with firewood.

Although the materials used in alchemy are collectively referred to as medicinal stones, they are actually subdivided into two types: "medicine" and "stone".

Medicine mainly refers to herbal medicines, and most of the medicinal herbs in Li Shizhen's "Compendium of Materia Medica" are herbal medicines, which are worthy of the word "Materia Medica". As for the stone, including the Zeng Qing that Xie Xiaoman is collecting now, it is more similar to the composition of ore, but it can also be used in medicine.

Whether it is alchemy or traditional Chinese medicine, many stones are used as prescriptions. Zeng Qing is a kind of sulfur, sulfur or anything can also be used in medicine.

As for the mutual scolding war against Chinese medicine after a thousand years, Xie Xiaoman didn't know much about it, so he didn't have too many ideas. As for alchemy, it is naturally not the same as traditional Chinese medicine.

Zeng Qing is not an easy medicine stone to obtain, it is not easy to find ores, and the most important thing is the process of removing its impurities and extracting its essence.

Xie Xiaoman was holding a large piece of Zeng Qingyuan Stone, holding it in his arms and looking at it, he couldn't help but feel extremely troublesome.

The reason why Zeng Qing is called Zeng Qing is because it naturally presents a dark cyan color, almost close to black. When it grows, it will be fused with other stones and minerals, so after getting the rough stone, it will have to go through fine carving to get a relatively pure Zowenite block.

This is not a simple matter, Xie Xiaoman took out the small chisel specially brought from his waist, and chiseled little by little, always feeling that the whole process is similar to cross-stitch, it is a precise job.

The tiny sound of tinkling clangs echoed softly in the valley, causing many timid animals to scatter, but there were also some daring animals who came to watch, including a familiar rabbit.

The rabbit jumped up to Xie Xiaoman's feet, sniffed curiously next to the falling fine stones, and looked up at Xie Xiaoman.

Xie Xiaoman naturally saw it too, so he greeted it with a smile: "I haven't thanked you yet, if it wasn't for you a few days ago, it would have been difficult for me to find that spider spirit." You're really good, how can you understand what I'm saying. ”

After receiving Xie Xiaoman's compliment, the little rabbit was very happy, and turned around twice in place, with his two ears standing high.

Xie Xiaoman couldn't help laughing: "But today I'm here to collect medicine, well, this thing is called Zeng Qing, and I use it for alchemy." It's hard to take out this thing, there are too many impurities. ”

The little rabbit shook his ears as if he was thinking about something. It jumped over to another rough stone, sniffed it, and poked it with its little paws.

Xie Xiaoman saw that it was cute and didn't care about it. It's the hairy body, which will rub Xie Xiaoman's legs from time to time, slightly itchy, but very interesting.

Smiling and continuing to chisel stones, Xie Xiaoman found that he didn't hate this kind of thing, but found it very interesting and able to meditate.

After a thousand years, it is popular to paint and reduce pressure, and it is estimated that it is not much different from the kind of thing I am doing now. But she doesn't have any pressure, she's a person, she doesn't have any big pursuits, and cultivating immortals is also at ease with what happens, and she was addicted to cutting trees before, and at this time she was happy to chisel stones.

There was a strange creaking sound in my ears, and it was not from the small chisel I had in hand. Xie Xiaoman stopped what he was doing, looked for a sound, but saw that the little rabbit at his feet was biting the stone quickly with his rabbit teeth, and the two rabbit teeth were moving fast like an electric drill, but in a moment's effort, a piece of rough stone was cleaned up a lot, revealing a few small pieces of pure Zeng Qinglai.

Xie Xiaoman was dumbfounded, and the little rabbit seemed to feel her gaze, raised his head, and shook his tail happily.

"I can't repay you for helping me like this." The strange things that happened to the little rabbit were really one after another, and although Xie Xiaoman was pleasantly surprised, he couldn't help but feel a little worried.

Anyway, this little rabbit is a little goblin after all, and Xie Xiaoman can't understand much about this kind of life until now.

If it's just an ordinary rabbit, you can just take it back and raise it yourself, but the little rabbit demon ......

The rabbit demon didn't know what Xie Xiaoman was thinking, at this time, he was biting happily, and continued to work like an electric drill, his little head shook and shook, which was interesting.

"Alright! At least I can't lose to you! Xie Xiaoman was amused by it, so he simply didn't care about those who didn't have it, and lowered his head and sat up with the work at hand.

Crunch, clang, the valley was filled with the sound of collecting medicine.

After the little rabbit demon cleaned up a piece of Zeng Qingyuan Stone, he was probably tired of playing, turned around and ran away, and disappeared into the grass in an instant.

Xie Xiaoman was stunned, but he also felt that it should be so, after all, the other party was also a life with a mind, and he had no power to control it, so he simply sighed slightly, and threw all the processed Zeng Qing into the cloth pocket.

He went to the ore next to him and chiseled a few pieces of rough stones, Xie Xiaoman saw that the back of the ore was already full of granite, so he knew that there were not many rough stones here, and he would find the next mineral in the future.

However, Zeng Qing also got a lot of these at hand, about four taels, enough to make a few pills.

What Guo Pu meant was to teach himself to refine a few pills that he could take now, such as the Huakun Pill, and in addition to Zeng Qing, he also needed an herb called Sankezhen.

Looking up at the sun, it was almost above. Xie Xiaoman decided to dispose of the remaining Zengqing Rough Stone first, and then go to pick three needles.
