"Daddy, what are you doing?"

In the courtyard, Pan Pan squatted on the ground, curiously watching Xu Ping who was not far away being busy. Pen %Fun %Pavilion www.biquge.info he held a small wooden stick in his hand, and wrote and drew on a copper plate seriously. There was a porcelain vase on the ground next to it, and the yellow liquid in it was a little uncomfortable to look at.

Xu Ping ignored Panpan and took care of himself writing and painting on the copper plate. That day, Shi Quanbin said that the charts of the new regulations were not convenient for typesetting, and Xu Ping remembered that movable type printing was convenient, but it could not be as good as the engraving. This is not a big deal for the common subset of scriptures and histories, and there are no pictures on those books, but if you want to print some popular reading materials or official documents of the imperial court, it is insufficient.

After thinking about it for a few days, Xu Ping remembered that he could use copperplate etching from his previous life for printing.

However, although Xu Ping knows the principle, it is not easy to do. First of all, the etching solution, fortunately, Xu Ping tossed a chemical reagent for a while when he was in Yongzhou, and finally remembered to use ferric chloride solution.

However, where is ferric chloride sold in this era? If you want to use it, you have to prepare it yourself.

Whenever he had to prepare these things by himself, Xu Ping had to sigh at the importance of the industrial base. The same simple chemical reagent involves a series of technical problems. To make iron chloride, it is best to have hydrochloric acid, and the best way to prepare hydrochloric acid in this age is to use sulfuric acid, and then the problem is concentrated on the preparation of sulfuric acid.

In Xu Ping's time, there were people in China who made sulfuric acid hundreds of years ago, but I don't know what it is, but it is called "alum oil" according to the preparation process. Just listen to the name, you know, it is made of green alum.

This process cannot be used for large-scale industrial production, and Xu Ping does not have that need, as long as he can make it in the laboratory, it is enough. In the smelting and casting yard of the third division, with the help of Guo Zheng, Xu Ping finally distilled sulfuric acid from the green alum, and then mixed it with salt to make hydrochloric acid, and finally dissolved iron directly. In this way, ferrous chloride is produced, and then copper oxide is used as an oxidant to produce a little chlorine gas, which is oxidized again to produce the appropriate ferric chloride.

Xu Ping can remember the general chemical reaction of this process, but where can he remember some details? What's more, there are things he didn't learn at all in his previous life. I can only grope with Guo Counsel little by little in the smelting and casting yard, especially the final step of using copper oxide as a catalyst to produce chlorine, and I wasted countless efforts and tried a variety of raw materials before I was barely successful.

This process made Guo Jian feel extremely magical, and became very interested, and after dealing with official business every day, he nested alone in the smelter, doing all kinds of strange experiments, and making something that even Xu Ping couldn't name. Guo Yan named these strange things himself, divided them into categories, and tried little by little, but he didn't know what strange things he would come up with in the end.

There was something at home today, Xu Ping came back early, so he brought the ferric chloride solution home and tried it himself.

Su Er came to be a guest today, Lin Suniang accompanied her in the house, and Pan Pan was so stuffy in the house that she came out to play with Xu Ping.

After drawing a board, Xu Ping carefully picked it up, found a place that was not facing the sun, and waited for it to dry slowly.

As soon as I turned around, I saw Panpan coming to the side of the small bottle, and was carefully touching the bottle with her little hand.

"What do you do? Be careful that your fingers are gone! ”

Xu Ping was startled, took a big step to Panpan's side, picked her up, and scolded her with a straight face.

Panpan twisted her nose and didn't care at all. She had already seen on the side that the liquid had dripped onto Daddy's hand, and nothing happened at all. Scare yourself with big words, do you still think you are a child?

Xu Ping also couldn't do anything about his daughter, so he stepped aside, drew a circle with his feet on the ground, put Panpan inside, and said with a serious face: "You are inside, you are not allowed to come out without my orders!" ”

Panpan was unhappy: "I didn't do anything wrong, why should I be punished?" ”

"And said that he had done nothing wrong! Daddy told you a long time ago that you can't touch that bottle, and it will burn your fingers if you get it! You are disobedient, as soon as I turn around, you will run over and touch yourself! ”

"Daddy, I'll take a look at your hand."

Xu Ping didn't know what Panpan was going to do, so he stretched out his hand in front of her.

"Here, here, and here," Pan Pan gestured on Xu Ping's arm, "I saw it all just now, and there were all the yellow water dripping on it." It's been a long time, why hasn't Daddy's hand melted yet? ”

Xu Ping didn't expect this little girl to be so difficult, so he had to say with a straight face: "Can you compare with me?" Daddy has practiced it! Besides, I'm so old that you're so old, with rough skin and thick flesh, where can it be dissolved so easily! ”

Pan Pan giggled, not believing Xu Ping's words at all.

The next day, after the morning court, Xu Ping went directly to the regulations editing office.

As soon as he entered the yamen, he saw Wang Gongchen and several people gathered there to discuss.

Xu Ping asked, "Early in the morning, what are you talking about here?" ”

Wang Gongchen sighed: "A few days ago, the case of collusion and corruption by the public officials was concluded, except for the leader of Salmon Island, all the rest of the people were stopped, and we are talking about it here." ”

Xu Ping said: "If you want me to say, this sentence is not too heavy." If it weren't for their status as a public official, the saint would have to lose a few heads this time, how could they just stop the matter? ”

Shamon Island is located outside Dengzhou, and it is a place where the imperial court is equipped with felons, and when you go there, you will die for a lifetime, and it is not far from the death penalty. There was still pressure on the court to cut dozens of people at a time, and in the end, it was still mismatched.

Li Zongyong, the household judge who came over to edit and repair the office today, said: "Not to mention those who are mismatched, there are nearly 800 public officials who have been suspended this time, and the remaining 4 or 500 people can't even maintain their daily affairs. Deputy envoy, you said that in the past few days, the three divisions and yamen are really busy, will you still recruit these people back? I got the news, many people have such thoughts, so they are not in a hurry to be stopped, and they are also discussing that they can't be reduced when they come back. ”

Xu Ping sneered: "Just let them dream of themselves!" This time, I went out of the Sansi Yamen, so don't think about coming back, otherwise so many people will not be busy in vain these days! Recruit these people back, and the three divisions are still as smoky as before! ”

"So what if you can't get busy?"

"Why do you call it busy? Why can't you get busy? In the past, there were more than 1,000 people in the three divisions, and there was still a backlog of things for several years, so do you really think that more people can handle things? If there is a shortage of manpower, they will be recruited again, and they can't collapse without them! ”

Several people stopped talking, but their expressions obviously didn't believe what Xu Ping said.

Xu Ping didn't bother to tell them in detail, no matter how good he said, it was better to make it useful for others to see.

Before leaving, Xu Ping said to a few people: "In a few days, the state officials transferred from Jingdong and Jingxi will enter the Third Division." You must not be idle, and in addition to compiling the regulations, you must explain the new regulations to these people. Newcomers are always more disciplined than old people, so they just take this opportunity to change the atmosphere of the three divisions! (To be continued.) )
