Three Kingdoms, I open a tavern in Xudu

"What's your name?"

Mrs. Ding saw that the servant girl was so scared, so she let go of her guard.

"Slave servant Xiaoqiu." said the servant girl.

"Okay, go and make medicine for the prime minister." Madam Ding nodded.

"Yes!"

Xiaoqiu lowered her head and stepped back slowly.

Cao Cao said, "Ma'am, a new maid, why be nervous?"

"After these things happened, I have to be cautious." Mrs. Ding said solemnly.

Cao Cao only felt warm in his heart, and then smiled warmly.

Xiaoqiu took Hua Tuo's medicine and went back to the back kitchen. She didn't dare to neglect, and immediately started to decoct the medicine.

However, in the process of putting down the medicine, she took out a blue dead branch from her body and put it in the medicine together.

"Almost discovered." Xiao Qiu muttered to himself.

-

The next morning, when Chen Yang woke up, Cao Ning and Zhang Chunhua were lying beside him.

As for Xiao Ru'er, last night he asked Diao Chan and Mrs. Gan to come over and take them with him for a night before he had the chance to mess around with the two wives.

Zhang Chunhua's body has not fully recovered, and Cao Ning can only bear it all in the end.

"Husband! Why are you awake?" Zhang Chunhua said softly.

Chen Yang got up from among them, and said with a smile: "I want to see Xiao Ru'er, she must be very uncomfortable without my father by her side."

Cao Ning smiled and said, "Sister, after we have Xiao Ru'er, we will fall out of favor."

Chen Yang kissed her lightly on the lips, pinched her little nose again, and said, "Silly girl, how could I let you fall out of favor? Wait for me to come back tonight."

Cao Ning exclaimed, turned over quickly, fell behind Zhang Chunhua, shook his head and said: "Husband, I don't want tonight, I almost couldn't sleep last night, you... are too bad!"

She hugged Zhang Chunhua from behind, and the two of them were naked. This scene made Chen Yang unable to avert his eyes.

"Bad husband, you are not allowed to enter our room tonight, get out!" Zhang Chunhua felt sorry for Ning'er and wanted to drive him away.

Chen Yang swallowed his saliva and had no choice but to leave the Nuan Pavilion, and soon arrived at the residence of Diao Chan and Gan Qian. He knocked on the door lightly.

"Come in!" Gan Qian's voice came from behind the door.

Chen Yang thought about Xiao Ru'er, so he pushed the door open and went in, but what he saw in front of him made his nose bleed again.

Just look at Gan Qian and Diao Chan sitting on the edge of the bed without even a single line on their bodies, the two of them hugging each other, this scene has to be as shocking as it can be.

"what……"

Gan Qian saw clearly that the person who came in was actually Chen Yang, she jumped up quickly and covered her body with the quilt.

"It must be my opening method is wrong!"

Chen Yang quickly turned around, walked outside, and closed the door.

After waiting outside for a long time, Chen Yang heard Gan Qian's voice from inside again: "General, we are ready!"

After Chen Yang entered the door again, she anxiously explained: "On weekdays, only maids come to see us. I thought it was maids who knocked on the door. I..."

Wow!

Before she could finish her words, Xiao Ru'er was also woken up on the small bed beside her, and burst into tears, which interrupted her explanation.

"My little Ru'er, father is here!"

Chen Yang hugged his daughter up and coaxed her for a while, then said embarrassingly: "I didn't see anything, you can continue."

He hugged his daughter and went out quickly to find Zhang Chunhua for food.

After one night, Xiao Ru'er was also hungry.

"Sister, what... what should I do?" Gan Qian lowered her head shyly.

Diao Chan thought for a moment, then whispered a few words in her ear, her cheeks became redder and shyer.

"It can't be like this!" Gan Qian shook her head and said.

After Chen Yang went back and fed Xiao Ru'er, he took her around the house again.

Xiao Ru'er likes to be lively, just like his mother.

Chen Yang thought of meeting Zhang Chunhua for the first time, she was a lively and active little girl, she married Chen Yang later, her personality became more restrained, unexpectedly being inherited by Xiao Ru'er.

"General Chen!"

Just as Chen Yang was about to go out, he met Chen Deng outside the door.

"Yuanlong is here, please come in!"

Chen Yang took him to the reception hall, and said again: "Yuanlong has worked hard during this time."

It can be seen that Chen Deng's skin is much darker than before, and his face is also covered with a layer of vicissitudes. It should be caused by those water conservancy projects in Xudu and he often appears in the wild.

"The general followed the prime minister to the north to conquer Yuan Shao and bring peace to the world. Compared with that, Yuan Long's work is not hard work!" Chen Deng said modestly.

"How's the progress of the reservoir?" Chen Yang asked.

"I came here this time because of the reservoir."

Chen Deng took out the blueprint from his body, and said, "I wanted to talk about the reservoir with the general yesterday, but I thought it was a full moon ceremony for the young lady, and it's not suitable to talk about serious matters, so I came to visit again today."

While speaking, he had already spread out the drawings and placed them on the table.

Holding Xiao Ru'er in his arms, Chen Yang leaned over to look at it for a while, and could see that this was the construction drawing for the location of the reservoir.

Chen Deng continued: "After our negotiation and persuasion, the villagers near the reservoir are willing to move away, and the farmland will also be used by us. Of course, we will not be less compensated, and the refugees who have been called back have also started construction. However, I found a problem. If we build a dam here to intercept the water source, it will be a bit difficult."

"How difficult is it?" Chen Yang asked curiously.

Chen Deng pointed to the drawing, the place where the dam was, and said: "According to the records in the "Agriculture Book" given by you, General, water will generate pressure when gathered together, that is, water pressure. We have already verified this point. The water source is gathered in this reservoir, and I am worried that the dam will not be able to withstand the pressure of the water, even if it is a wall made of cement, it will be difficult."

As he spoke, he pointed to the surrounding area of ​​the reservoir drawing, and continued: "This side is blocked by mountains, and the pressure is sufficient to withstand the pressure. Only the dam, we have tested the strength of the concrete, and feel that the dam may be difficult to build."

After listening to his statement, Chen Yang probably understood something, and said with a smile: "Although concrete is hard, it also has a disadvantage, that is, its poor tensile performance. You can add steel bars to it when making concrete blocks..."

What tensile properties, Chen Deng was confused.

Before he could ask what those were, Chen Yang had already ordered someone to fetch a pen and paper.

He wrote and drew for a while, and continued: "You follow this structure, smelt iron ore into steel, and then make this kind of mold, inject cement, so that the force of the dam wall will be stronger."

When making cement, Chen Yang forgot this.

But Chen Deng is also very good, with his ancient knowledge, he can think so much.

Chen Deng picked up the drawing and looked at it for a while, only to see that Chen Yang had drawn in detail the method of how steel bars were made into molds, and even the method of making steel.

Fortunately, Chen Yang had learned related knowledge before, so he was no stranger to these things.

"These are the steel bars I'm talking about. As for the tensile properties, you can understand it as the main characteristics of steel bars..."

Next, Chen Yang briefly explained to him how to combine steel bars and cement.

Although Chen Deng was not Ma Jun, his ability to accept was not weak at all, and he nodded half-understanding while listening.
