Chapter 1842

"Yes!" Sun Yingying agreed. "There are also many medical things here. If they can be popularized, they can also greatly improve the health and medical level of the people."

During the communication between sun YingYing and Bai Yixiu, sun Dahai was a little anxious. "My Lord, Yingying, don't say it now, OK? I just saw that your majesty and the prince have looked here for several times. Is it too impolite for us to salute again?"

"Uncle Sun said let's go now. If we don't see it, we can't pretend we don't see it now." Wang an Bai Yixiu said with a smile, and then turned and walked over.

Sun Dahai could not laugh or cry when he heard Bai Yixiu's words, but this is what his son said about Lao Tzu. It's like a joke, but others can't.

Sun Dahai and sun Yingying followed Bai Yixiu and came to Emperor Kangming and crown prince Bai Yishan.

As soon as he was about to salute, Emperor Kang Ming stopped him, "don't be polite. Today, I don't have so many rites. King an, why are you here now?"

"My son is preparing to build a different courtyard in Tangshan. He knows Yingying has many ideas, so he invited YingYing and his son to design it together.

At that time, there will also be the yard of the father emperor and the prince's brother. Be sure to make it novel, so that the father emperor and the prince's brother can come for leisure and entertainment when they are free. "Wang an Bai Yixiu said with a smile, he can't be comfortable, so he doesn't care about his father and brother.

In particular, there are so many rights in the hands of my father and brother. I can't be filial.

"Ha ha, very good!" emperor Kang Ming nodded. "You are all filial. By the way, you should repair. Can this cement be used to build river dams?"

Bai Yixiu nodded when he heard this, "yes, but the current cement proportion is used to build roads. It can take ten years at most. If you change some proportions, it can take at least twenty years."

"Ah?" emperor Kangming was shocked, stunned, stunned, and couldn't believe it. "What did you say? Yi Xiu, tell me again. I didn't seem to hear it clearly just now."

Seeing this, Bai Yixiu suddenly understood the shock of his father, the emperor and the prince. Every year, there are eight million silver to repair the levee. These silver will be allocated without hesitation, otherwise the levee will burst and there will be no harvest in some places.

If the dam can be built at one time, it can save a lot of money in ten or twenty years.

"I said that cement can be used to repair dams, and it is very strong. In addition, if the proportion and hardness of cement are adjusted, it can last at least 20 years," Bai Yixiu said confidently, which he can be sure of.

Hearing this, Emperor Kangming was not calm. He thought that even if the cement was expensive, it would be very cost-effective to use it for three years. At least he didn't have to do so much labor.

"Twenty years, twenty years!" emperor Kang Ming said excitedly, "it's appropriate to fix it. Then you can adjust the proportion and send it to me tomorrow! Prince, go back to the palace immediately. I have something to arrange."

Seeing this, Bai Yixiu hurriedly said, "father, don't wait for tomorrow. I have the data here now. I have calculated the proportion of cement, sand and stones before. If some places have deep water or high strength, it will be even stronger if cement, steel bars and other things are added inside. These sons haven't calculated. Father can let people from the Ministry of work test."
