At this time, Murong Xuan did not expect that in order to please Rong Yanran and her father, he began to think about how to deal with his father.

When Prime Minister Rong finished speaking when he saw the prince, he signaled Zezhong to follow him, and the latter still had a taste of unsatisfactoryness.

However, Rong Yanran heard Murong Xuan shouting: "Yan'er, are you racing against the snail?" She immediately responded, "I'll come right away." In fact, she had long wanted to get rid of this fifth brother. He was so easy to learn that she always tried her best to make a lie.

Just now he asked: "Liu Mei, you said that planting grass in various trees upstream is conducive to water control. What's going on?"

Rong Yanran began to explain patiently: "Fifth brother, think that the river floods because of the rain. If there are too many trees, the rain will slow down when it falls, and it will not cause too much impact. Some of them will be absorbed by the land. Moreover, trees grow on the ground, which can prevent soil erosion by itself."

"Soil erosion means that there are no trees or grass on the surface of the land. When it is washed by rain or blown by wind, the good soil will flow into the river. Over time, it will block the river channel and there will be no good crops in the ground. This is probably what it means." Rong Yanran looked at Rong Zezhong's curious and admiring gaze based on her own understanding, and explained proudly.

Rong Zezhong said excitedly: "Yes, yes, why didn't I think of these? I dredged the river and saw a lot of mud and sand flowing down from the upper reaches, but I didn't know how to fundamentally stop it, but I just built the dam. This is a good way. Dry land is indeed more likely to lose good soil than those covered with trees and weeds. But where did you know this? Who did you learn this word from?"

Rong Yanran was proud. When she heard the last question he asked, she was stunned. She actually approached herself with the same blind spot. She seemed to show her wisdom just now, and she talked endlessly about the ancient example of water control that grandpa told her, and unconsciously led to Rong Zezhong's final question: "Yan'er, where did you know?" "Liu Mei, who taught you these?"

This is the third time he asked such a question, damn it! Rong Yanran pretended to smile: "Brother, you know, as I saw it from a book just now."

"Where is that book? It won't be lost again, right?" Rong Zezhong stared at her tightly, as if she would immediately expose my lie if she dared to say it again.

Rong Yanran hesitated for a while and explained slowly: "No, I met an old man on the road and showed it to me. I didn't know that Brother Fifth, you need it so much, otherwise I would definitely stay for you."

She observed his face as she said, but unfortunately, the expression she read was: He doesn't believe it!

At this moment, Murong Xuan called her with a stingy look and immediately ran over.

The group returned to the government office and finished their meal happily. Rong Zezhong wanted to discuss some water control with her, but Prime Minister Rong stopped him with a smile: "Your sister is here for the first time. Today we don't talk about anything else, just enjoy family affection."

Rong Zezhong had no choice but to give up and go back tonight to think carefully about the method Rong Yanran said.
