Cement is not that difficult to make.

The raw materials are lime and clay, which are ground into powder with a large stone mill, and then put into a calciner to be calcined, and then ground into powder after firing, mixed with gypsum powder.

When you use it, you can add some water, sand or gravel and lime, and anyone who has built a house knows what to do.

As for green bricks and tiles, bricks began to develop during the Zhou Dynasty, and as for ceramic tiles, many foreign dynasties called the Tang Dynasty a country of porcelain.

The next thing is the copper pipe, this thing costs money, a lot of copper coins, the copper coins of the Tang Dynasty are more expensive than silver, theoretically speaking, the consistent copper coins are one or two silver, and the law stipulates that the consistent (缗) is a thousand Kaiyuan Tongbao, but many times the consistent money in the folk circulation is only more than 700 to 800, no way, Datang lacks copper! Therefore, Cheng Chubi's water pump made of copper was naturally impeached by the imperial envoy.

Looking at the copper pipes, Cheng Chubi is also quite distressed, but in order to be able to live the life of his dreams, it is worth spending more money.

The next day, craftsmen were gathered and a major renovation of the house began. Moving bricks and bricks, removing wood blocks, and cement and cement, in full swing, the princess's mansion has simply become a construction site.

"Are you going to demolish the princess's mansion?" Chai Lingyu was a little inexplicable by Cheng Chubi, I don't know what Cheng Chubi is going to do? Demolition of the house in the early morning?

Early in the morning, with a group of people busy working, the good horses are about to become masons.

"Almost, if I could, I would definitely tear down the princess's mansion and rebuild it." Cheng Chubi said happily, although the Tang Dynasty style building is still very good-looking, but people who have lived in brick houses know that this kind of house often needs to be repaired, otherwise when it rains, it will be a rainstorm outside, and a light rain inside.

Although the glazed tiles of the princess's mansion are still quite durable, they will occasionally fall into the water.

"It has to be done before the rainstorm." Cheng Chubi couldn't help but say.

"What the hell are you doing?" Chai Lingyu was even more puzzled.

"Of course, the house was remodeled, first with a layer of cement on the ground and then with tiles." Cheng Chuliang took Chai Lingyu's hand and walked up in the room: "Let's get a small room here and use it as a bathroom, so that it will be convenient to take a bath in the future, and it won't stink." ”

"How is this possible?" Chai Lingyu doesn't believe it, isn't the toilet smelly? How do you sleep after building in a house?

"Dig a septic tank, then make a toilet, and here is a squatting pit, seal it with water, and rinse it with water after each pull. And here, let's get a big bathroom and install a big bathtub, and the bathtub is already burning, and it won't be long before it burns. Cheng Chubi said as he spoke, the whole person looked extremely excited, pulled Chai Lingyu out of the door, came to the back of the house, and said: "Here, that's right, this is here, let's make a big cistern, pump the well water from here into the cistern, and then connect the iron pipe, send the water to our room, and send it to the kitchen." This is Datang's tap water system! ”

"Isn't this cistern very high?" Chai Lingyu's brows couldn't help frowning slightly, and said, "Then how to send water inside?" ”

"You don't have to worry about this, I've ordered someone to build a foot-operated pumping machine that uses air pressure to send water into it." Cheng Chubi said proudly.

Who are we? We are Datang inventors, and this thing is not difficult for us.

"And what is this thing?"

"Cement!"

"Cement?"

"An architectural artifact." Cheng Chubi said triumphantly: "Wait a few days, you will know." ”

"And where are we going to sleep tonight?"

"Let's sleep in the guest room first." Cheng Chubi thought about it and said, Princess Xinping's Mansion covers a large area, so there are still a lot of rooms, even if they are modified one by one, it is estimated that there is no one that cannot be completed in a year.

Cheng Chubi hurriedly commanded the people here to get busy, first digging the septic tank, and then laying the floor, as for the original wooden walls, they were directly demolished, and then replaced with green bricks, and after they were done, a layer of white lime was smeared on the outside.

After finishing this, I dug a large pool on the ground and transformed it into a swimming pool, surrounded by tiles, and the water was clear after the water was released.

Then he did other things, in short, for most of the month, in addition to going to the palace to teach his children Taijiquan, he was almost busy at home.

Lan Ruoxuan.

Lan Ruoxuan has returned to his former calm, since something like that happened, many people dare not come to Lan Ruoxuan to drink anymore, although Lan Ruoxuan's wine is very good, but after all, it is a place where the dead have been killed, who would dare to come?

Therefore, Lan Ruoxuan became cold again.

In the wing room on the second floor, a figure stood in a daze, since being detained, the three pandas were accepted, and then the funny man disappeared.

Dugu Lanruo's brows furrowed slightly, and her eyes lacked the divine light of the past.

"How long has he not been here?" Dugu Lan couldn't help asking.

"It's been twenty days." Anu thought for a moment and said.

"It's been twenty days, it's been twenty days."

"Why don't we go find him?" Anu said.

"No, as a woman, if you come to the door like this, you will be looked down upon by others!" Dugu Lan couldn't help but shake her head and said, "Forget it, hey, maybe he also dislikes my ugly ......"

And at this time, in the Zhao Guogong Mansion.

Changsun Yao looked at Changsun Wuji with an aggrieved face, the tears in his eyes kept rolling, and he couldn't help but sigh when he looked at his daughter like this.

"Hey! My father doesn't want you to pass the door of the Cheng family, but the old man Cheng chases after his father every day and asks, there is no way to be a father, you have to understand, this time the Cheng family has given us so many benefits, if you don't send you there, it will inevitably ruin the credibility of our eldest grandson family, who will dare to cooperate with our eldest grandson family in the future? Changsun Wuji sighed helplessly, the matter of Changsun Yao has already been rumored, and now except for Cheng Chubi, who would dare to ask for her?

"Is it for the sake of the family's interests that you have to sacrifice your daughter and let her be someone else's concubine?" Changsun Yao's face couldn't help but show tears of grievance.

"Daughter, rest assured, as long as our eldest grandson's family is still there, as long as this Tang Dynasty is still surnamed Li, no one will dare to treat you as a concubine." The eldest grandson Wuji said bitterly, in fact, he was also bitter in his heart, and he was also very aggrieved.

His daughter can't be a wife, this is simply a slap in the mouth, but the scoundrel of the Cheng family has already relied on his daughter, who would dare to marry him if he didn't marry him?

At the same time, in the mountains and forests outside Chang'an City, two figures were constantly flickering in the forest.

"Whoosh!"

I saw a figure flash and landed on the crown of a large tree, and another figure flashed and also landed on the canopy not far away, standing on the crown like a light bird.

Both of them are dressed in white, one of them is quite pretty, and the other is pretty.

"You've been chasing for a few days, what do you want?" The woman in white couldn't help frowning slightly, holding the sword in her hand, if the other party chased after her, she would be polite.

The beautiful man held the sword in his arms and said lightly, "There's a nasty guy who wants to see you." ”

"Him?"

"That's right!"

"Let him do it himself!"

"He's too weak!"
