Han Yi has always been very clear about his positioning. For a long time, he regarded himself as a pawn and his bottom line was very low. As long as he didn't kill him or touch his family, he would do anything. He didn't even care how many people were monitoring him. Anyway, when he really used the people, he was basically a few people from Yangzhou with him. Even Peng Jing, Tan Dong and others started to let them enter their core circle on the eve of that crisis.

No matter what, this piece is passive.

But now it is different. He is no longer a chess piece. It’s not that he doesn’t want to continue to move on, but that there are not many people who can use his chess piece now. He is already a chess player. Of course, he will not be passive anymore. He will start to take the initiative in everything.

Gu Qingcheng is one of them.

After lunch, Han Yi and Sang Mu took a carriage out of the city.

After walking for an hour, they came to a relatively remote place, but they saw that the surroundings were very empty and there were few birds and beasts. There was only a courtyard made of bricks and tiles. The construction style was different from the mainstream architectural style today and looked very strange.

Han Yi and Sang Mu just arrived in front of the door when the courtyard door opened immediately, but saw two guards with knives coming out of the inside and holding their fists, "The villain has met the boss, the boss."

Han Yi nodded and walked inside, "Is there any life?"

"Here I am."

"Go and inform me."

"Abide by the order!"

When Han Yi came to the yard, he saw that the yard was filled with various utensils, and there were countless jars and cans. There were three or four of the Guangdan furnaces with different sizes and shapes. Although they wanted to be trash here, they were all very exquisite.

When Sang Mu saw this scene, he said with a distressed heart: "My benefactor, these porcelain tools cost us a lot of money. They ordered them from Lao Tao's house. Xu Changming's requirements were very strict. If there was a slight mistake, he would throw them away. Alas..."

Speaking of Xu Changming, Sang Mu is really resentful.

If he spent tens of thousands of pounds a person, how can he not complain? But when Han Yi went home to mourn, he would say hello to him. In terms of money, he tried to satisfy Xu Changming and not to worry about him.

Han Yi smiled and said, "It was just that I was stimulating consumption."

Sang Mu smiled and didn't make a sound. In fact, the old Tao family was not willing to make these things for them, because these things were completely useless for ordinary people and were not easy to price. It was really mulberry and clay would never refuse.

After a while, a middle-aged man wearing a white hat and dressed in white ran out from inside, his face full of surprise, "Dong... Master, you are here!"

It is Xu Changming.

Han Yi nodded and saw that the beard on his face was shaved and his clothes were very clean and tidy. He smiled and said, "No, good, very clean."

Xu Changming said, "This is all the instructions of the boss, you will tell me. How dare Changming disobey?"

In the past, Xu Changming was so refined that he was like a beggar, but there was nothing on his body that was clean. Han Yi had no other requirement for him, just to keep him clean, including the house. Of course, Xu Changming didn't need to clean up by himself. Han Yi specially helped him find four mutes to take care of his diet and daily life, because his work was very confidential, and mutes were the most suitable.

Han Yi smiled and said, "Don't invite me into your laboratory."

Xu Changming subconsciously said, "President, please come in." After that, he suddenly took back his steps, "President, do you want to put on this clothes?" He pointed to the white coat on his body again.

Han Yi smiled and said, "I have always followed other people's rules very much."

Xu Changming immediately understood and immediately called a mute aunt and asked her to bring two sets of work clothes.

Soon, the aunt brought two sets of white work clothes.

Han Yi and Sang Mu both changed into work clothes, including gloves.

It was only then that I entered the laboratory, and it was very clean and clean, and at a glance it was very expensive because it was all made of marble, especially the large laboratory bench in the middle, and the whole piece of marble, just the shipping cost. Moreover, each table corresponds to a window for lighting.

However, Sang Mu said that 50,000 yuan does not include the cost of the laboratory, because it was designed by Han Yi himself.

There are many utensils placed on the table, which are considered strange to mulberry wood.

In fact, these utensils are just some chemical utensils, of course Han Yi told Xu Changming, including alcohol lamps.

Han Yi gave Xu Changming a chemical material. Although it included some chemical knowledge, such as how to purify, distillate, or other methods, it mainly talked about how to do chemical experiments, rather than just fiddling in the alchemy furnace as before.

Han Yi looked at it briefly and said, "Long Live, today I heard from Sang Mu that you asked him to help you find twenty slaves. What kind of staff do you lack here? That slave is not smart. I can help you find a more suitable candidate, and you will be obedient in keeping it."

Xu Changming was stunned for a moment and said, "I'm not short of manpower, but... I've just developed a new drug that has been used on many rabbits. The effect is very good, but it has not been applied to humans yet, so I want to find twenty slaves to test the medicine for me."

Just knowing that this is the case, this guy's morality still needs to be improved! Han Yi was a little excited and said, "What new drug is it?"

"Please wait a moment, boss."

Xu Changming quickly walked into a small cottage in the laboratory. After a while, he walked out, but saw a small porcelain bottle in his hand and said, "Owner, this is the result of my research in the past few years." After that, he uncovered the lid.

Han Yi looked at it, but saw a red powder inside and said, "Is this useful for external trauma?"

Xu Changming said: "It's very useful. I have tried it on a hundred rabbits and have achieved very few treatment results. Among them, there are ten rabbits. I deliberately made their wounds worse. Then I used this medicine again, and seven of them were healed. This medicine can not only be applied to the outside, but also eaten, but it will leave red scars on the wounds."

Is it an antibiotic? I don’t see antibiotics in this color! Han Yi nodded and said, “What did you do?”

Xu Changming said excitedly: "This is a method I came up with a local method."

"What kind of method?"

"I used to know that some people often have mold and long haired flour applied to small wounds. It is said that it has a good effect. I thought that this mold may have a therapeutic effect. In addition, you taught me the purification techniques, I thought that if the mold could be purified, it might have excellent results. So I made all kinds of molds and found ways to purify them. However, there has never been a breakthrough. I found that after the mold was stored, although it could turn into various colors, it could not treat the wound."

Xu Changming pointed at some bottles.

Han Yi walked up, picked up a bottle and opened it. He found that it was a beige block. He opened another bottle and found that it was a very purple powder. He couldn't help but look curious because these colors were all those he had never seen in the Tang Dynasty. His eyes were flashing, but he said, "So you keep talking."

Xu Changming said oh, and continued, "Until one day, I took a rabbit to experiment. When I was cutting the wound, my hand didn't catch it. The rabbit jumped out and knocked over many things, including a bottle of red mold. The mold just sprinkled on the rabbit's wound. I never thought that the rabbit would heal soon, so I specially studied this red dye, and really let me get this new medicine. But I hadn't tried it on someone, and I dared not tell the owner."

He heard what he said, it looked like penicillin, but it was not red either! What kind of medicine did this guy come up with? Han Yi was a little confused and said, "Have you written a work log as I told me?"

“Some, some.”

Xu Changming ran in quickly again, then ran out with a big notebook, handed it to Han Yi, and gasped slightly, "This is the research work log on this medicine."

Han Yi came outside the house with his work log and sat in the yard to read it. As soon as he looked at the first page, he started sweating because it was written on it as a pure Chinese chemical reaction. Although Xu Changming has always taken the chemical route, his previous medicines were extracted by alchemy. In fact, alchemy is chemistry. But he now has no concept of microorganisms, so he still writes it with the same set of alchemy. This is obviously a microbial reaction. You just write it so big, which makes it very awkward.

While Han Yi looked, he had to think about what reaction would be here.

But after getting used to it, the value contained in this work log is gradually revealed. In fact, it is written in a very organized manner, and every detail is written in very detailed, including many reactions.

Of course, Han Yi didn't see the end from the beginning. He mainly selected a few main synthesis reactions and then closed the work log.

But Xu Changming, who was standing beside him, was extremely nervous because Han Yi was sweating after watching for a while. He was very afraid of Han Yi. He swallowed and asked carefully: "Owner, is there something wrong?"

Han Yi smiled and said, "It's very good. It's just about the drug testing. How many of these twenty people are enough? I'll find a way to do this. How many of these medicines do you have in your hands now?"

Xu Changming said: "There are more than 200 bottles."

"It's quite a lot!"

"Hehe! I'm here all day long, and I'm developing this new drug."

Han Yi nodded and said, "You are ready, I will get it. Oh, you should also pay attention to your health. You are the scarce talent around me."

Xu Changming was moved and tears were almost coming out, saying, "Thank you, thank you, thank you."

Han Yi said: "Okay, I'll go back first, oh, I have to take this diary back and take a look. I'll send it to you in two days."

Xu Changming said: "It's okay, it's okay, this belongs to you, the boss."

"This is not mine. This is your sweat over the past few years. I will return it to Zhao intact."

Han Yi said, then stood up and left here.

After getting on the carriage, Han Yi said to Sangmu: "How much did Xu Changming cost us?"

Sang Mudao: "Fifty thousand cents."

Han Yi said: "Do you still remember the powders of various colors just now?"

Sang Mu nodded.

Han Yi said: "That's actually a kind of dye. This technology alone is a priceless treasure. Not to mention 100,000 guan, even 200,000 guan, the beauty of freedom is willing to spend this money."

"Two...two hundred thousand coins?" Sang Mu said tremblingly.

Han Yi said: "You know, this is not worth the medicine yet. If it is really calculated, it will be worth a hundred times more profitable. However, this technology cannot be sold to the beauty of freedom. Dye technology involves many aspects and is very important for the gold store. We have to produce this dye ourselves and then sell it to the beauty of freedom. It just so happens that the court is about to issue new currency recently. After the meeting, I have to go to the dye workshop to take a look. We will discuss it in detail then."

Sang Mu still didn't come back to his senses, but just nodded dumbly and said, "I understand."

In fact, it is a microbial dye, but Xu Changming is aiming for a new drug. He only cares about the efficacy of the medicine and what kind of dyes he has never thought about. But Han Yi is a person who knows the goods. This is a very big breakthrough in dye technology. You must know that dyes are extracted from animals and plants today.

This is definitely a priceless treasure!
