After the Chen family's father and son left, Ailang got up and went to the military camp. He was very tired of the messy government affairs, but he liked to stay in the military camp to supervise the training of the officers and soldiers, or gather with men of similar age to him and chat with bullshits.

At this time, in Diao Chan's courtyard, several maids heard Diao Chan's call and quickly stepped in. Diao Chan had already sat up, her hair was extremely lazy. Although the maids were all women, they still couldn't help but lose their minds when they saw this scene. They couldn't help but think of what happened not long ago. They all turned red with their heads down and were busy, but they didn't say anything.

Diao Chan wanted to stand up and go to the dressing table to dress. But as soon as she stood up, a numb feeling immediately surged up from her thighs. She couldn't help but snorted and fell back to the bed. Her delicate face was blushing and autumn waves were flowing.

When several maids heard the movement, they hurriedly surrounded him. Seeing Diao Chan's appearance, they didn't know what was going on. The flush that had faded from their faces appeared again. Lu'er and another maid quickly stepped forward and helped Diao Chan up, left and right, and walked to the dressing table to help Diao Chan dress.

Ailang stayed in the military camp until evening. On the way back to the city, he passed a farmland outside the city and saw many farmers using wooden barrels and other objects from the stream flowing through the farmland to irrigate the farmland. It was not only time-consuming, but also very inefficient. Ailang was very surprised and asked Dian Wei around him: "Isn't there a water truck? Why do those farmers still irrigate like this?" Dian Wei showed a confused look and asked, "Lord, what is the water truck?"

Ailang was surprised and said, "The water truck is a kind of equipment that can help people fetch water to irrigate the farmland! Haven't you seen it before?"

Dian Wei shook his head.

Ailang was surprised in his heart and thought to himself: 'Hasn't the waterwheel been invented in this era?' Thinking of this, he hurried back to his mansion.

As soon as Ailang came back, he didn't have time to have dinner. He called the official in charge of agricultural affairs in the governor's office and asked, "What kind of irrigation do you use for farmland?"

The agricultural administration official was stunned, then clasped his fists and said, "That's right, just use a wooden barrel and a spoon or something."

"Is there no water truck?" Ailang asked hurriedly.

The agricultural administration official shook his head blankly, clasped his fists and said, "I am ignorant and don't know what the waterwheel is?"

Ailang gestured in the air with his hands: "It is made of bamboo and wood, which can easily push water from a low place to irrigate the farmland. You won't really not know, right?"

The agricultural administration official hurriedly said, "I have never heard of such convenient equipment." Then he said suspiciously: "Is this possible?"

Ailang became excited and said to the agricultural administration official: "Come here tomorrow, I will show you something good." The agricultural administration official clasped his fists and agreed, retreating with a lot of question marks.

That night, after dinner, Ailang buried herself in the study and took a stroke and kept drawing. Until midnight, the lamp in the study was still on. Yan and Diao Chan saw that the lamp in the study was still on, so they could not rest at ease. So they wanted to prepare some food for Ailang, and came to the kitchen at the same time. When the two women saw each other, they were stunned at first, and then they met each other, smiled at each other, and then started busy in the kitchen. After a while, two exquisite and fragrant midnight snacks were prepared. Yan made mung bean cake, while Diao Chan cooked a bowl of flower rice porridge, and the two snacks were dry and wet, which complemented each other. It has to be said that Yan and Diao Chan were really smart outside. Not only were they beautiful, but they also had such talent. They were really Ailang's virtuous support!

The two girls came to the study with midnight snacks. Ai Lang was concentrating on the desk, and he didn't even notice his beautiful wife. He couldn't help but feel very surprised, and at the same time he was very curious about what their husband was doing.

The two girls came to the desk with midnight snacks, put the midnight snacks in their hands on the table, and looked at Ailang. They saw a large piece of white silk that had never seen before. The most eye-catching thing in the middle was a huge object like a round wheel. But if it was a wheel, it was still very different from the wheel, that is, it was just a round shape. There were many small things around the big round wheel, which were square and round, and quite exquisite. I don’t know what it was for.

The two women looked at each other, looking confused.

Ailang suddenly put down his brush and laughed, "It's done!"

The two women were confused, but when they saw this scene, they couldn't help but bow: "Congratulations to your husband!"

Ailang discovered the two women at this time and smiled and said, "Are you here?" Then he showed the silk to the two women like offering treasures, and said, "Look, this is a water truck! You can use the power of the water to rotate and drive the water from the river to irrigate the farmland!"

The two women were surprised. Yan couldn't help asking, "Can it be able to fetch water by itself? It's so magical?" Diao Chan couldn't help but say, "Isn't such a thing like a legendary magic weapon?" As he said that, he kept looking at the strange things painted on the silk, but he couldn't feel anything magical about them.

Ailang smiled and said, "It's just that amazing! With such things, our grain output will definitely increase greatly!" Then he saw the midnight snacks brought by the two girls, and he felt hungry. He picked up the mung bean cake and ate them, picking up the flowers and rice porridge to drink them, and shouting that he was satisfied. The two girls looked at Ailang with a smile, looking very happy.

Early the next morning, the agricultural administration official hurried to the hall of the governor's mansion to wait for his order. After waiting for a long time, Ailang came. The agricultural administration official quickly saluted.

Ailang asked him to come forward and spread the silk. The agricultural officials had never seen a water truck before. When they saw the pictures on the silk, they couldn't help but widen their eyes and felt inexplicably.

Ailang explained to the agricultural administration officials carefully to the pictures on the silk. After all, the agricultural administration officials did this. After hearing Ailang's detailed explanation, he was shocked and excited. Ailang asked him to hurry up and try it out near Xuzhou City first. If possible, it would be fully promoted. The agricultural administration officials bowed and hurried down.

Speaking of Chen Gong's envoy, Huainan was finally back. He led Yuan Shu's envoy Han Yin to walk on the official road to Xuzhou City, and guided the surrounding scenery to introduce the customs and customs of Xuzhou to Han Yin. Han Yin came over and saw all the people living and working in peace, busy farmland and bustling with merchants. He couldn't help but feel that Huainan under the ruler's rule was far inferior to Xuzhou! With this idea, it's not surprising why he had been defeated repeatedly before when facing Lu Bu. His thoughts on his mind were even stronger!
