Before leaving, the Crown Prince said to Qin Wu: "Today, I have a hearty chat with Miss Qin Wu, and this Crown Prince is very interested. Miss Qin Wu is well-informed and gentle. If anyone can marry such a beauty, they will be blessed by the heavens. "

Qin Wu smiled so sweetly.

After returning to the residence, Fourth Prince and Qin Feng sat in the front hall as they drank tea. It was still early in the morning, and there was nothing to do, so they could only drink tea and chat.

"It seems that the crown prince has taken a fancy to your sister. Once your sister marries into the crown prince, we will probably meet again in the future and pay back the humiliation we suffered today." Fourth Prince's tone was full of concern, but he had an evil smile on his face.

Qin Feng scoffed, "Thank you, Fourth Prince, for your concern, but I am not the only one who is going to be paid back twice as much, and it seems that Fourth Prince has not given my sister much face either."

Fourth Prince shrugged his shoulders as if he did not care. "It's interesting to be able to be together with Madam in the deep water. I really look forward to Madam's performance."

"Then you better not have any expectations. The greater the expectation, the greater the disappointment. If I am able to protect myself and leave you to suffer, don't blame me."

"How could that be? It's Madam who is stuck in a quagmire, so I will take off my boots and give up. I will live and die with Madam without any regrets."

"I really do not hope for that day to come. If there comes a day, Fourth Prince must remember to be careful, it is very possible that I will borrow your power to escape from this mud pit, leaving you alone to accumulate energy." Although Qin Feng's words were filled with viciousness, Fourth Prince still did not mind.

"Often, the mouth of a knife is the mouth of a bean, and the heart of a person. Madam, madam, you have truly become more and more lovable." Fourth Prince leaned close to Qin Feng's face and exhaled hot air into Qin Feng's neck.

Just as Qin Feng wanted to flare up, a little servant barged in and saw Fourth Prince standing next to Qin Feng's face, looking as if she was about to kiss him. The little servant was only fifteen or sixteen years old, and was just starting to understand. He turned around and walked out.

Even though Fourth Prince was thick-skinned, being seen by a child was extremely awkward. He could only helplessly stand up, pretend to cough and not look at Qin Feng's angry eyes.

"Uh, that person, uh, the one just now, come in." Fourth Prince shouted.

The servant lowered his head and walked in unsteadily. After looking at Qin Feng whose face was cold, she quickly kneeled down and said: "This brat was reckless. I didn't see anything. I really didn't see anything."

"Alright, who asked you to say that. So what if you see anything? A man is so bashful, I'm sure he'll be someone afraid of his wife in the future. Come on, what did you want to report just now?" Fourth Prince asked.

"Yes, it's His Highness the Fifth Prince who requested an audience. He's waiting for him in the front courtyard."

"Invite him as soon as possible!"

It was said that the relationship between the Fourth Prince and the Fourth Prince was the best, so it seemed like the rumors were true, Qin Feng thought, but the Fourth Prince had an unrestrained personality, while the latter was as calm as a virgin. She had never imagined that the relationship between the two of them was so close.

"Fourth Brother, Fourth Sister." Upon meeting, the Fifth Prince bowed to the two of them. Qin Feng blessed her body and returned the greeting.

The Fourth Prince did not care about all this and sat down, asking: "Why has the Fifth Brother been here all this while, did something happen in the palace?"

"Since the two of you want to talk about national affairs, then I won't disturb you." Just as Qin Feng was about to leave, she was stopped by the Fourth Prince.

"Fifth Brother is not an outsider, you should go back to your room now because you have nothing to do, so you should stay and listen, and share your opinion."

Qin Feng thought about it, but since she had nothing to do, she nodded in agreement and sat back down.

"The morning assembly today, the South River reported that it rained heavily a while ago, and the dam that was built last year was once again destroyed. The ocean was raging, and over ten thousand farmers were killed, and all the good food was destroyed." After Fifth Prince finished speaking, he sighed, but in his heart, there was nothing he could do.

The Fourth Prince also frowned, "When it comes to the rainy season, the Southern River will be devoid of life. I have long advised the father to relocate the people on both sides of the river, but this imperial edict will not stop there."

"It's not that the Emperor isn't living here, it's just that the Southern River is filled with water from both sides of the river. The population is great, and they all depend on the Southern River for their livelihood throughout their lifetimes. Let alone the fact that so many people want to move to other places, even if they are willing to leave their hometowns, that is still a problem. " Fifth Prince said helplessly.

Fourth Prince nodded his head, "That's right. There are a lot of people living on both sides of the Nanjiang River, and no one wants to leave their hometown. The South River crop is different from other places. If we move, there will be no job to live on. In the end, we would be displaced and our families would be ruined. "

Qin Feng was also shocked. Although floods as natural disasters were common in the modern world, but to a large extent, it was controlled. Very few people died, but in the ancient times, it was a difficult problem that no one could solve.

"Every year, this Nan Jiang will build a dam, and every year, it will be a flood." "I've used up a lot of silver, but it's useless. I really don't know what to do." Although the Fourth Prince was usually uninhibited and unrestrained, he was still an ordinary citizen. Upon hearing such news, his heart was extremely depressed.

The Fifth Prince said helplessly: "The father has asked the officials to come up with a plan, but none of them are able to do it. In the end, he ordered the officials to wait for the rainy season to pass, and then proceed with the construction of the dam. However, the treasury was not full to begin with. Once this expenditure was included, it would inevitably be empty. "It doesn't matter if he can solve the Southern River Cataclysm, but if he were to be washed away again, this silver would be like a piece of cake."

"Fifth Prince, I wonder if you guys have tried to unblock the flood?" Qin Feng interrupted, if that was not possible, then why did she not learn how to use Da Yu's method to evacuate the water?

The Fifth Prince was not angry because of Qin Feng's interruption. Instead, he said with interest: "You have thought of this plan before, you do not understand the Southern River, it has nine bends and eighteen bends, and there are many branches, when you force your way through, the water would surge, and at that time it would spread even wider."

Qin Feng frowned, it seemed that this was more difficult than she had thought, but since she had heard of the human tragedy, how could she just stand by and watch?

"I wonder if there is any map of the Nanjiang region?" Perhaps I can find a way to solve this problem, but don't expect too much. " Qin Feng didn't really understand anything in this area.

Hearing Qin Feng's words, the Fourth Prince immediately got someone to bring a map for them. He placed it on the table for the three to study.

Qin Feng felt that this Nan Jiang looked very familiar, similar to a modern river.

"Fifth Prince, when did the flood of the Southern River start?" Qin Feng asked.

"Five years ago, the flood was only downstream when it was raining a lot, so many locals moved upstream. However, in recent years, the upper and middle reaches of the river have also started flooding. The people are suffering unspeakably." Fifth Prince pointed to the map and said.

Qin Feng asked again: "Was the upstream of the Nanjiang River originally vast and boundless forests? Did the local people cut down all the trees in order to farm the environs? "

Although the Fourth Prince did not know why Qin Feng was asking, he felt that maybe Qin Feng could solve this big problem, so she answered immediately: Yes, farmers need to cultivate their food, otherwise what would they eat?

"If it wasn't for the fact that people from the river went upstream and cut down the trees before surrounding the lake with the field, the disaster wouldn't have happened today." Qin Feng shook her head. Foolishness was always the source of disaster. If the people of Nan Jiang were to break through nature, they would definitely be punished by nature.

"Fourth royal concubine, please explain in detail." Fifth Prince knew that Qin Feng must have a plan in her mind, so he asked anxiously.

Qin Feng nodded and said, "Actually, I can't explain it either. But as you said just now, the flood was always downstream, and only gradually spread upstream in recent years. And this process of expansion was the process of the people living downstream moving upstream. Wherever he went, he would have to eat, and he would cut down trees to reclaim his land. The trees on both sides of the Nanjiang River should have been gloomy and gloomy, but there should be no lack of hundred-year-old trees. After a long period of growth, these plants and trees have long been deeply rooted and have fused with the underground water to form a line. "

When the Fifth Prince heard Qin Feng's analysis, his eyes lit up. "Could it be because the commoners of the Southern River have cut down these trees, causing the underground water veins to change?"

"That's right, you must have heard that the roots of those trees are very complicated and deeply buried in the ground. Their existence can very well prevent soil and water loss and tightly grip the land together. Even with the constant heavy rain and a large portion of forest upstream, they can still properly absorb the excess water and then, through the naturally formed underground passage, go straight down into the sea." Without the trees, the land will be loose, and if you charge you will collapse. The destruction of the underground river cannot be drained, and only the surface can be exposed, which is why such a large flood occurred. If you go to the scene and take a look, there will definitely be some parts that will collapse. " Qin Feng revealed everything she knew, but she had no intention to hold back.

"Then what about the solution?" At this time, Fifth Prince had a whole new level of respect for Qin Feng, he thought to himself, as expected of someone that Fourth Brother has set his eyes on, even the officials of the officials in charge of the officials thought themselves inferior.

"Return the land to the forest, and move some of the people upstream to the downstream. "This method may not be able to solve the most urgent problem, but it is still a method to treat the root of the problem." Qin Feng could only come up with this kind of countermeasure. After all, her main focus was not on this area.

Fifth Brother did not mind at all: "The Southern River has always been troubled, and for some reason, now that I know the reason, everything will be much easier. Fifth Brother will thank Fourth Sister on behalf of the suffering citizens of the Southern River, I will report to father tomorrow, and as long as this matter is resolved, Fourth Sister will be the number one meritorious general of my Phantom Fire Kingdom."

Qin Feng did not want to become so famous, "Please do not mention me, Fifth Prince. Sometimes, if you attract too much attention, it might not be a good thing."

Fifth Prince was also a person who understood everything and agreed.
