The third elder brother was satisfied with what he heard, and said to Yinzhen with satisfaction: "Fourth brother do a good job, although this errand of the Ministry of Engineering is hard and trivial, but it is a training person!" This is the ...... that Huang Ama trusts with you"

The third elder brother said something, and then Yinzhen pretended to be blue, and the third elder brother finally patted Yinzhen on the shoulder, smiled and left the Ministry of Industry with a proud face.

After the third elder brother left, Yinzhen put away the expression on his face and began to do the things in hand.

Although the marriage made Yinzhen happy, he couldn't give up the reform plan of the Ministry of Industry!

Yinzhen plans to get the cement out and then build the road, and they all say that if you want to get rich, you must first build the road, and the transportation is convenient and extends in all directions in order to develop the economy.

The road must be repaired, and it must be repaired, there can be no tofu scum project, he has to sum it up, after all, the profits in it are big, if anyone wants to intervene and be greedy, who will he cry to!

The formula is easy to get done, but the person who presides over the road repair is a little difficult to do! Yinzhen plans to let his eldest brother preside over the road repair, but now that Yuan Kai is on an errand by Kangxi's side, how to talk about this matter, and how to take out the cement recipe reasonably and abruptly, this needs to be summed up!

Yinzhen worked in the Ministry of Industry for a long time, thinking about the wife in the house, and decided not to stay and work overtime, the work can never be done, and it is serious to accompany his wife to eat.

When Yinzhen went back, Xin Ru was washing, and Xin Ru was really tired last night, and she didn't wake up until noon.

Xin Ru saw Yinzhen coming back from an errand, and said a little angrily: "Aren't you going to run an errand?" How did you get back? ”

Yin Zhen also knew that he had gone too far, and flattered: "Didn't you want to come back to accompany Fujin for dinner?" Is Fujin rested? ”

"What do you say?"

"It's for the husband, but Fujin can't doubt the ability of the husband in the future."

Xin Ru thought of last night and decided that he would not doubt his ability in the future.

After Xinru washed up, Yinzhen asked people to serve food, and after eating, Yinzhen said: "I'm going to get the cement out, what do you think?" ”

Xin Ru heard Yinzhen talk about cement, and her first reaction was: "Do you want to build roads?" ”

"Yes, only when the road is repaired can the economy develop, and the road must be repaired."

Xin Ru asked again: "You tell me this, do you have any plans?" ”

"I thought, when the cement experiment is ready, let your eldest brother preside over the road repair, and I don't feel at ease when I hand it over to others."

Xin Ru heard Yinzhen say this, and also knew that even if only the entire road in the capital was repaired, there were many places to make a fuss, if you found an unreliable person to preside, one did not hold the greed, the life of the road was not long, it was better not to repair it.

Although Xin Ru was very happy to hear Yinzhen say this, she still asked: "You trust my eldest brother so much?" ”

"Your eldest brother won't covet that little profit, not to mention that the last thing your Suo Yuluo family lacks now is silver, and that little bit of silver is not enough to take risks!"

All right! Yin Zhen doesn't seem to have anything wrong with saying this.

Yinzhen decided what to do next, and then began to get busy.

Yinzhen copied the cement down, planned to let people secretly match it, and then experimented again.

Cement square: limestone 67-75%; clay 10-15%; Iron ore 0.5-1.5%; Coal?? 8.5-11% (from Baidu)

The raw materials of cement recipes are relatively easy to obtain, and the main thing Yinzhen needs to arrange is to find a suitable and more dramatic story to make the appearance of cement legendary.

Yin Zhen thought that he had heard the legendary invention stories of those scientists in modern times, and felt that with such stories, it would be convenient to promote his country's scientific cause in the future, and it would also allow future generations to learn the spirit of hard exploration, which needed to be summed up.

Yinzhen told Xin Ru about his thoughts, and then Xin Ru thought for a while and said, "If you can rest assured, leave this matter to me." ”

Yin Zhen really planned to let Xin Ru give an idea, he didn't plan to say that he couldn't think of it, but he wanted to find something for Xin Ru to do.

After saving a long time, Xinru was bored in the house alone.
