Prince Bai Yishan thought for a moment and said, "father, what you said is that the production of the royal family is only enough to build dams, and the rich families of princes and nobles can't use cement. If folk forces are allowed to produce, it may increase a lot of production!"

Emperor Kangming thought about it, and it is also a good way to mobilize the strength of the people. "The prince means that the imperial court produces and builds all kinds of waterways, and then we sell the formula for making cement to those people who can produce it! The cement produced is used for the people."

Bai Yishan thought for a moment and nodded. "My son felt that such a good thing could be used by thousands of families at a small cost, but the houses built were very strong, fireproof and waterproof, much stronger than those wooden houses! This was also a good news for the common people."

Hearing this, Emperor Kangming nodded, "when King xuan'an enters the palace, I want to ask the Duke of the town and his family, as well as whether it is feasible to use cement for civilian use?"

Prince Bai Yishan also knows that the best thing about cement is king an, "yes, father!"

Bai Yixiu, who received a call from the eunuch, has just returned from the workshop.

Last time I saw sun Yingying, I talked about expanding the production of the workshop and opening branches in Jinling, Guangling, Gusu, Yuhang and other places.

Those places have more rich households and can make more profits by opening branches.

Bai Yixiu thought that the subsequent construction of the Academy needed countless gold and silver. Opening a branch can indeed make a lot of money.

He knew that his father and brother were diligent and thrifty, and there was no extra money to support him in building the Academy.

Therefore, Bai Yixiu can only think of his own way, and this is also his dream, so he must speed up his pace.

After receiving the summons, Bai Yixiu did not delay and directly followed the eunuch into the palace.

The prince of emperor Kangming finished his business and went directly to the place where the empress of Fengqi palace was located.

The crown princess is now in a big month. She usually only walks around the east palace. She doesn't care about anything except greeting her when necessary.

The empress did not expect that the prince of emperor Kangming would come and asked people to add more food.

Ready to eat, Bai Yixiu is coming.

The queen was surprised, "why did Yixiu enter the palace today? Please say hello?"

Emperor Kangming smiled, "I have something to call him, so let him enter the palace!"

Hearing this, the queen nodded and did not continue to inquire. Emperor Kangming would say if he wanted to say, but if he didn't want to say, she asked, and Emperor Kangming wouldn't say.

"The style of the clothes sent by her son is simple, but it's really cool! I heard it was designed by Yingying. You said that although the two people are quite different in age, how can they have the same mind?" the queen was worried that Bai Yixiu and sun Yingying were too old to go together.

But now look, age is not a problem in front of them.

Wang An had a miserable life in the past twenty years. Maybe he won't live one day.

Therefore, even though king an has been cured for most of his illness, the queen, Emperor Kangming and even the crown prince are still very tolerant of king an Bai Yixiu.

Emperor Kangming also nodded, "it's really good! I'm also wearing it! When the second girl and hairpin of the town government are ready, I'll do it for my son's marriage."

Although there are many marriages between women in the great Zhou Dynasty at the age of 17 or 18, Emperor Kangming certainly loves his son after waiting for his son for so many years.

Just then, king an Bai Yixiu came in.

Bai Yixiu smiled and sat down with his father, Queen Mother and crown prince.
