Han Yi has always been very clear about his positioning, for a long time, he just regarded himself as a chess piece, and the bottom line was also very low, as long as he didn't kill him, he didn't move his family, he didn't even care how many people around him were watching him, anyway, what he really used at the beginning were basically a few people from Yangzhou with him, even Peng Jing and Tan Dong, they were only on the eve of that crisis that they began to let them enter their inner circle.

Either way, the pawn is passive.

But now it's different, he's no longer a chess piece, it's not that he doesn't want to continue to be a pawn, but now there are not many people who can use his chess piece, he is already a chess player, of course he won't be passive anymore, he has to start taking the initiative in everything.

Gu Qingcheng is one of them.

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

After walking for an hour, they came to a relatively remote place, but saw that the surrounding area was very empty, birds and beasts were rare, and there was only a large compound made of bricks and tiles, which was built in a style different from the mainstream architectural style of today, and looked very peculiar.

Han Yi and Sang Mu had just come to the door, and the courtyard door was immediately opened, but they saw two guards with knives coming out of it and clasping their fists, "The villain has seen the proprietor, the chief manager." ”

Han Yi snorted and walked inside, "Is there a long life?" ”

"Yes."

"Go tell me about it."

"Yes!"

Han Yi came to the courtyard, only to see that the courtyard was full of all kinds of utensils, there were countless altars and jars, and there were three or four different sizes and shapes in the Dan furnace alone.

When Sang Mu saw this scene, he said distressedly: "Engong, these porcelains cost us a lot of money, and they were specially ordered from the old Tao family, and Xu Changsheng's requirements are very strict, and if there is a slight mistake, he will throw it away, alas, ......." ”

Speaking of Xu Changming, Sangmu's resentment is really not small.

A person spent tens of thousands of yuan, so can he, the person in charge of money, not complain, but when Han Yi went home to keep filial piety before, he greeted him, and in terms of money, he tried his best to meet Xu Chang's life, and didn't worry about him.

Han Yi said with a smile: "At that time, consumption was stimulated. ”

Mulberry smiled and didn't make a sound. In fact, the old potters are reluctant to make these things for them, because these things are completely useless to ordinary people, and they are not easy to price.

After a while, I saw a middle-aged man wearing a white hat and white clothes running out of it, his face full of surprise, "Dong... Proprietor, you're here! ”

It was Xu Changsheng.

Han Yi nodded, seeing that the beard on his face was clean, and his clothes were very clean and tidy, he smiled: "Not bad, not bad, quite clean." ”

Xu Changming said: "This is all ordered by you, the proprietor, where does Changsheng dare to disobey." ”

In the past, Xu Changming's alchemy was like a beggar, and no part of his body was clean, Han Yi had no other requirements for him, just to keep him clean and tidy, including the house, of course, this did not need Xu Changming 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 is very confidential, and mutes are the most suitable.

Han Yi smiled: "Don't invite me to go in and see your laboratory." ”

Xu Changming subconsciously said: "The proprietor, please come in." With that, he suddenly retracted the steps he had taken, "Proprietor, do you want to put on this dress?" He gestured to his lab coat again.

Han Yi smiled: "I have always been very obedient to other people's rules. ”

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

Soon, the aunt brought two sets of white overalls.

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

Only then did I enter the laboratory, which was very neat and clean, and it could be seen at a glance that the cost was expensive, because all of them were made of marble, especially the big experimental table in the middle, the whole piece of marble, I don't know how much it cost to pay for shipping alone, and each table corresponds to a window, just for lighting.

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

And on the table, there are a lot of strange utensils for mulberry wood.

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

Han Yi originally took a book of chemistry materials to Xu Changming, although it included some chemical knowledge, such as how to purify, distill, or other ways, but the main thing was how to do chemical experiments, not the same as before, knowing that the alchemy furnace was going on.

Han Yi looked at it a little and said, "Changshou, today I heard Sang Mu say, you asked him to help you find twenty slaves, what manpower do you lack here, that slave is not smart, I can help you find a more suitable candidate, and the custody is obedient." ”

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

I know that this is the case, this guy's morality still needs to be improved! Han Yi was slightly excited: "What is the new drug?" ”

"Proprietor, please wait a moment."

Xu Changsheng walked quickly to a small room in the laboratory, and after a while, he walked out, but saw that he was holding a small porcelain vase in his hand, and said, "Proprietor, this is the research result of my research in the past few years." With that, he lifted the lid.

Han Yi stared at it, but saw that it was a red powder inside, and said, "This is useful for external injuries?" ”

Xu Changming said: "It's very useful, I've interviewed a hundred rabbits, and they have achieved very little healing effect, among which there are ten rabbits, I also deliberately aggravated their wounds, and then used this medicine, and then used this medicine, and as a result, seven of them were cured, this medicine can not only be applied to the outside, but also can be eaten, but when applied to the wound, it will leave a red scar." ”

Is it an antibiotic? I haven't seen antibiotics of this color! Han Yi nodded and said, "What did you do here?" ”

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

"What kind of dirt?"

"I used to know that some people often put moldy and hairy flour on small wounds, and it was said to have a good effect, so I thought that this mold might have the effect of treating external injuries, and I thought that if I could purify this mold, it might have an excellent effect, so I made all kinds of mold and tried to purify them. However, there has been no breakthrough, and I found that although the mold can magically change into a variety of colors, it just can't heal wounds. ”

Xu Changming pointed to some bottles.

Han Yi stepped forward, picked up a bottle and opened it, and found that it was a beige lump, and opened another bottle, and found that it was a very special purple powder, and couldn't help but show curiosity, because these colors were all things he had never seen in the Tang Dynasty, his eyes flashed, but his mouth said: "You go on." ”

Xu Changming sighed, and continued: "Until one day, I took a rabbit to experiment, when I cut the wound, this hand did not grasp, the rabbit jumped out at once, knocked over many of my things, including a bottle of reddened mold, the mold just sprinkled on the rabbit's wound, I never thought that the rabbit was quickly healed, so I specialized in this red dye, and really let me make this new medicine." But I haven't tried it on people, and I don't dare to tell the proprietor. ”

Listening to him say this, it looks like penicillin, but penicillin is not red either! What the hell did this guy come up with? Han Yi was a little confused when he heard this, and said, "Have you written a work log as I instructed?" ”

"Yes, yes."

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

Han Yi came outside the house with the work log, sat in the courtyard and read it, just read the first page, and began to sweat, because what was written on it was a pure Chinese chemical reaction, although Xu Changsheng has always taken the chemical route, but his previous drugs were all refined by alchemy, in fact, alchemy is chemistry, but he doesn't have the concept of microorganisms now, and he still writes in the same set of alchemy, which is obviously a microbial reaction, you just write it so big, it looks very awkward.

While Han Yi watched, he had to think about what the reaction would be.

But after getting used to it, the value contained in this work diary gradually revealed, in fact, it was written very well, and every detail was written in great detail, including a lot of reactions.

Of course, Han Yi didn't see the end from the beginning, he mainly selected a few major synthesis reactions and looked at them, and then closed the work log.

But Xu Changsheng on the side was very nervous, because Han Yi was sweating as soon as he looked at it for a while, he was very afraid of Han Yi, swallowed a mouthful, and asked cautiously: "Owner, is there something wrong?" ”

Han Yi smiled: "Very good, just about the test of medicine, where are these twenty people enough, I will find a way, how many of these drugs do you have in your hands now?" ”

Xu Changming said: "There are more than two hundred bottles. ”

"That's a lot!"

"Hey, hey! I've been here all day long working on this new drug. ”

Han Yi nodded and said, "You are ready, I will let someone pick it up." Oh, you have to pay attention to your body, you are the most scarce talent around me. ”

Xu Changming's tears of emotion were about to come out, and he said, "Thank you, thank you, owner." ”

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

Xu Changming said: "It's okay, it's okay, this originally belonged to the proprietor." ”

"This is not mine, this is your sweat in the past few years, and I will return to Zhao."

Han Yi said and stood up and left the place.

After getting into the carriage, Han Yi said to Sang Mu: "You said earlier how much did Xu Changsheng cost us?" ”

Sang Mu said: "Fifty thousand." ”

Han Yi said: "Do you remember those powders of various colors?" ”

Mulberry nodded.

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

"Two... 200,000? Mulberry said in a trembling voice.

Han Yi said: "You know, this is not the value of this medicine, if it is really calculated, there will be a hundred times the benefit." However, of course, this technology cannot be sold to the beauty of freedom, dye technology involves many aspects, it is very important for the gold bank, we have to produce this dye ourselves, and then sell it to the beauty of freedom, it just so happens that the imperial court is going to issue a new currency recently, and after the meeting, I have to go to the dye workshop to see, and then we will discuss it in detail. ”

Sang Mu still didn't come back to his senses, but nodded and said, "I know." ”

In fact, it is a microbial dye, but Xu Changming is going to the new drug, he only cares about the efficacy, what dyes, he has never thought about it, but Han Yi is a person who knows goods, this is a very big breakthrough in dye technology, you must know that today's dyes are still extracted from animals and plants.

It's priceless!
