Yang Zijin coughed and said, "Well... Senior Liang went to the dam after waking up. He said he was going to survey, but he hasn't come back yet."

"He went there alone?" Mo Li frowned slightly after hearing this and then asked Yang Zijin.

Yang Zijin nodded.

"Got it. I'll find him now." As Mo Li said, he turned and prepared to go out.

As he finished speaking, he heard someone outside the door said, "Don't bother. I'm back."

They looked outside. Liang Cheng was covered with mud, and there was some on his face.

"Senior Liang, why don't you wait for me to go together? After being washed by the flood, the road was tough to walk." Upon seeing this, Mo Li hurried to Liang Cheng and said.

Unexpectedly, Liang Cheng felt unhappy after listening to it. He looked at Mo Li and said, "Well, do you think I'm so useless?"

When Liang Cheng said so, Mo Li didn't know how to reply to him for a while.

"Senior Liang, you have misunderstood Mo Li. He is worried about your safety." Yang Zijin, on the side, smiled at Liang Cheng.

Unexpectedly, Liang Cheng glanced at Mo Li and then continued, "Is there any food to eat? I am hungry."

"Yes. Yes. Please come inside, Senior Liang." Mo Li said hurriedly.

In the room, Qiao Shu, Dean Shen, and others were all seated together. At this moment, seeing a dirty old man walk in, they couldn't help but look at him.

Qiao Shu instinctively covered her nose with a veil.

Liang Cheng saw that there was a seat on the side and sat down.

He ignored the eyes of others and ate by himself.

At this time, Yang Zijin walked forward and introduced him to everyone, "This is the artisan, Liang Cheng. He was invited by Marquis to rebuild the dam this time."

"It's the Artisan Liang. I heard about you in Jing City. I didn't expect to meet you here. Sorry I didn't recognize you." After hearing this, Shen Yang stood up and said to Liang Cheng.

Liang Cheng didn't lift his head and continued eating the food.

Upon seeing this, Yang Zijin hurriedly stepped forward to mediate, "Dean Shen, I think Senior Liang should be hungry. Let's eat, everybody. The food will be cold immediately."

Shen Yang smiled awkwardly at Yang Zijin and then sat down.

Then, Yang Zijin said to Mo Li, "Sit down and eat."

Mo Li nodded, walked next to Liang Cheng, and sat down.

Yang Zijin also sat down. She looked at the table. There were stir-fried shredded potatoes and braised potatoes. All of them were made of the potatoes that she let Lan bring to the kitchen today.

And everyone liked these two dishes.

After dinner, everyone left, and Yang Zijin called Mo Li.

"Your Highness, what's the matter?" Mo Li asked.

At this time, Yang Zijin asked Mo Li, "How do you think the two plates of potatoes on the table?"

Mo Li felt puzzled, "Not bad."

"Mo Li, I have an idea." Yang Zijin said.

Mo Li looked at Yang Zijin and said, "Your Highness, please tell me."

"The two plates of potatoes we ate tonight were planted by me when we first came to Jiandu." Yang Zijin continued.

After hearing this, Mo Li couldn't help asking, "Are these potatoes planted by Your Highness?"

"Yes, Jiandu has a large population. Since there is no food to buy, it is not a long-term solution to go on like this way. We have to figure out a solution by ourselves." Yang Zijin nodded and said.

After hearing this, Mo Li frowned slightly, "Your Highness, you mean that let everyone plant potatoes? Will it take a long time?"

"No, the soil in Jiandu is fertile, and the climate is suitable. These potatoes can be eaten in just one month, and the yield is very high." Yang Zijin explained to Mo Li.

At this moment, Mo Li nodded and then said, "But the planting method will have to trouble Your Highness to teach these people."

"There is no problem, but you have to go to other places and buy some potatoes." Yang Zijin continued.

"Okay, I will order someone to buy."

As Mo Li said, he walked out.

During the period, Yang Zijin was told by Lan that Jiandu was not rich in potatoes. Rice was grown here for a year because every autumn, the farmers had to hand in a large amount of rice to the government.

Meanwhile, they had to feed the family, so every household had no extra fields to grow other things.

However, Lan told her that she had buried a sprouting potato in the yard before, and later a lot of potatoes grew.

Later, when the neighbors knew this, they learned to bury the whole potatoes in the yard, but they didn't cut them apart.

After hearing this, Yang Zijin decided to express her thoughts. Now, as long as they could fill their stomachs, it was a good thing.

Counting the days, if they planted the potatoes now, and the potatoes would be harvested when the food ran out. At that time, the potatoes could solve the food problem, and it also could be transported to other places for sale or exchange for something they needed.

After the days were stabilized, they could plant their original crops again.

In the end, Yang Zijin hadn't thought that it was she who taught Jiandu people to grow potatoes, which would make every household in Jiandu rich in a short time.

When Liang Cheng returned to the house, he shut himself up.

During the day, he went to survey the topography of the dam. Compared with the time he came here before, it hadn't changed too much, except for the river's widening.

After one night, Liang Cheng finally figured out the structure of the dam.

However, he always felt that the internal structure of the dam was not strong enough. In order to prolong the dam's service life, the internal structure must be considered first.

But no matter how he amended, he felt dissatisfied. He always felt that something was missing.

For this reason, Liang Cheng was perplexed.

Later, he decided to recheck the dam. Maybe he could think of a better way.

So, he opened the door, put the drawing between his arms, and walked outside.

Before he left the yard, the drawings fell from Liang Cheng.

Yesterday, Yang Zijin talked to Mo Li about planting potatoes. Now, Yang Zijin wanted to check the situation of the victims. When she had just walked out of the room, she saw a piece of paper in the courtyard.

So she went forward and picked it up. Yang Zijin couldn't help but frown. It looked like the dam drawing designed by Liang Cheng. How could it fall into the yard?

At this moment, she walked to the room where Liang Cheng lived and knocked on the door gently, "Senior Liang, are you there?"

Without hearing a response, Yang Zijin asked again, "Senior Liang, are you there?"

However, still, no one responded to her. She thought Liang Cheng should have gone out, so the drawing had been dropped in the courtyard.

If he found that the drawing was gone, he would definitely come back and look for it. So, Yang Zijin walked to the stone table in the courtyard and sat. She decided to wait for Liang Cheng to come back to find the drawing before she went out.

After Yang Zijin sat down, she carefully looked at the drawings designed by Liang Cheng.

She couldn't help but admire him. As expected, highly skilled people always had a weird temper!

His design was as good as the modern one.

The upper drainage holes could be used to release water when the rainfall was heavy. And there were grooves for storing water, which could be used to irrigate crops in dry days.

Then, Yang Zijin continued to look, and she saw that the dam's internal structure needed improvement.

Modern flood control dams generally used triangular frames, which were strong and could reduce the impact force of floods.

It was just that the frame inside this design was square. Although it looked solid, it still couldn't resist it when it encountered a flood. After all, the impact force of the water was immeasurable.

Just thinking about it, Yang Zijin saw Liang Cheng returning from the outside in a hurry and looking for something.

Of course, Yang Zijin knew that Liang Cheng was looking for the drawing.

At this time, Yang Zijin got up and walked forward. She took out the drawing and asked, "Senior Liang is looking for this?"

Liang Cheng heard the sound, raised his head, and saw the drawing in Yang Zijin's hand. He quickly took it and looked at it carefully.

Then, he smiled and nodded, "Yes. That's it. I found it. I found it."

"Thank you." Liang Cheng said to Yang Zijin at this time, and then he turned around to leave.

At this time, Yang Zijin said, "I think there is a place that can be altered slightly."

"What?" Liang Cheng stopped after listening. He turned around and asked Yang Zijin.

Then, Yang Zijin repeated, "I said it has a place that can be altered."

"Can you understand the drawing?" Liang Cheng looked at Yang Zijin with an unbelievable look.

Yang Zijin smiled and said, "A little bit."

"Then, which side do you think needs to be changed?" Liang Cheng asked suspiciously.

Yang Zijin walked to the side and sat down. Then, she said, "The structure of the dam."

What Yang Zijin said was the problem that plagued Liang Cheng.

"Does Your Highness know how to change it?" Liang Cheng walked up to Yang Zijin with the drawing at this time. He sat down and asked.

Then, Yang Zijin didn't talk in a roundabout way. She said directly, "I just looked at the drawing. And I felt that your drawing was very considerate. However, considering its service life, I think that it would be more suitable to change the structure into a triangular frame."

"Triangular frame. Yes, why didn't I think of that? The triangular frame can not only save materials but also reduce the damage to the dam caused by the impact force of water." Liang Cheng couldn't help saying excitedly.

Then he looked at Yang Zijin with an incredible look. He couldn't help paying respect to Yang Zijin in his heart.

"Thank you, Your Highness. I was rude to you before, and I hope Your Highness won't care about it." At this time, Liang Cheng bowed to Yang Zijin.

Yang Zijin smiled and shook her head, "You don't need to be too polite, Senior Liang. I'm just expressing my own opinions. The rest needs to be done by yourself."

Liang Cheng was like Uncle Liu, who would not condescend to the identity of the others. Only like-minded people could get their attention.

"Then, I'll go to modify the drawing." Liang Cheng said as he took the drawing and walked to his room.

He shook his head as he walked, "Why didn't I think of that?"

Yang Zijin couldn't help but smile after seeing it, and then she walked down the mountain.

As soon as she walked down the mountain, she saw Mo Li.
