Li Yuanai went to Lawyer Pei's residence as an appointment and met Princess Linhai, the sixteenth sister whom she had not seen for many years.

Princess Linhai was very happy and excited to see her family who had been away from for a long time, but she did not dare to express her feelings too much because of her worries.

Li Yuanai was extremely embarrassed.

As a time traveler, he doesn't really recognize his Li family's bloodline.

The relationship with Li Shimin, Li Zhi, Xiao Yizi and Changle originated from Li Yuanai's own memory, and the real key is that it comes from the years of getting along.

Feelings are cultivated through constant contact.

When Princess Linhai got married, Li Yuanai was still young and had no memories. She had no contact for more than ten years, so she was almost no different from strangers.

Li Yuanai could not treat it as a relative, so he could only treat it as a friend.

The one who is really enthusiastic is Lawyer Pei. He is quite talkative and tells the difficulty of his and Princess Linhai over the years.

Especially when it comes to Bianzhou's experience, it is full of emotion and passion. In words, it intentionally or unintentionally attributes Bianzhou's prosperity to itself.

Li Yuanai cooperated and praised and amazed. He knew his advantages: young.

The terrible opponents in this world are often not those who are extremely smart, but those who are wise and foolish in the depths.

Just like Li Zhi!

Because no one deliberately guards against a fool.

No one regarded him as an opponent, and no one had seen him directly, so when he took action, no one could have thought that he had ulterior motives.

By the time Li Tai really realized it, it was too late.

If one of Li Chengqian and Li Tai looked at Li Zhi at the right time, they would not be able to reach their current status.

Li Yuanai knew that in the eyes of Lawyer Pei, he was the kind of young man who had a skill but no life experience. He was very good at fooling around and was happy to do so. He heard him talk about the development of Bianzhou in detail.

It was not until dusk that Li Yuanai said goodbye and left.

When he returned to the inn, Luo Tong had already returned, but Yan Liben still went out and did not return.

Li Yuanai asked Luo Tong about the results of this.

Luo Tong: "I asked some fishermen well. The fishermen said that they were fishing on the Bian River and had never seen any blockage. They had no effect on their fishing. However, in recent years, the imperial court's grain ships have often stranded. According to what they said, most of them happened after the late autumn, mostly in winter, and did not affect their fishing."

"Thanks for your hard work!"

Li Yuanai patted Luo Tong's shoulder, digesting the news brought by Luo Tong in his mind, and suddenly said: "In autumn and winter? What do fishermen say, how did they solve the stranding problem?"

Luo Tong nodded and said, "One person said that it was not the Bian River blocking, but the grain ship was transported too much, and the large ship had heavy draft, which made the grain ship stranded. The court arranged manpower and unloaded part of the cargo on the ship, so the grain ship could pass."

Li Yuanai seized the key and said, "In this way, the Bian River cannot be considered a blockage, it is just that it is restricted by the natural environment and the water level has been lowered."

In the rainy season in spring and summer, the water level rises, the water level is less rainy in autumn and winter, and the water level drops. This is the law of nature.

Li Yuanai strode to the hall, took out the report prepared by Lawyer Pei from the case table, and dragged it to the Bian River to block the record.

"The third year of Zhenguan, the fourth year of Zhenguan, the late autumn of the eighth year of Zhenguan, the ninth year of Zhenguan, the late autumn of Zhenguan, the late autumn of Zhenguan, the late autumn of Zhenguan, the late autumn of Zhenguan, the late autumn of Zhenguan, the late autumn of Zhenguan, the fifth year of Zhenguan..."

These are all years when the Bian River is blocked.

Li Yuanai closed his eyes and thought deeply: In the third year of Zhenguan, the fourth year of Zhenguan was the Tang Dynasty destroyed the Turks, the eighth year of Zhenguan, the ninth year of Zhenguan, the Tang Dynasty destroyed the Tuyuhun, the thirteenth year of Zhenguan, the fourteenth year of Zhenguan, the Tang Dynasty destroyed the Gaochang, and the fifteenth year of Zhenguan was the Tang Dynasty attacking Xueyantuo...

Whenever there is a large war, the Bian River will definitely be blocked.

This is no accident.

It was the increase in the imperial court's demand for food, which made the food tight, and the shipping pressure suddenly increased. Then it encountered the blockage caused by the fall and winter seasons, and the water level decreased, and multiple factors were caused.

This kind of blockage is not a problem with the Bian River itself, but more importantly, external factors.

That night, Yan Liben returned to the inn with tired steps. He did not rush to rest and came to Li Yuanai to report today's results.

"Your Highness, this is the current situation of the Bian River that I have calculated today. It is a bit different from what the governor Pei said. I found that even in autumn and winter, merchant ships on the Bian River remain the same, and there is no sign of blockage. However, there are records of blockages in grain ships, as well as records of hiring labor and transporting grain."

Li Yuanai nodded and said, "I already understand this matter. The Bian River has abundant water resources and can be opened on the river all year round. Only when the grain ship is heavy and the water is too deep, it is difficult to pass. Therefore, it is necessary to say that some of the grain can be unloaded before it can be passed."

Yan Liben was stunned for a while and said, "What should I do? It's not worth it if I really want to build a dam for this."

Li Yuanai nodded and said, "We thought of going together."

The dam can indeed solve the problems existing in the Bian River.

However, the manpower and material resources spent on building a dam are also astronomical.

The choice between building a dam just for the overweight grain transport ship is not easy to make a conclusion.

"By the way, do you think it is possible to directly lead a river to flow into the Bian River without building a dam? The Bian River is not short of water. Even in the autumn and winter, it can still be used for merchant ships and cargo ships, but there is only a little bit. If other tributaries can be used to flow into the Bian River, supplement that little bit. In this way, there is no need to spend all your effort to build the dam?"

Yan Liben's eyes lit up and he slapped his thigh and said, "Your Highness is so good to make a suggestion, I think it is feasible. This Bianzhou is surrounded by five lakes and four rivers, and the water resources are particularly abundant. Drawing water into Bian can solve this problem well."

Li Yuanai hurriedly said: "Take the water network terrain map near Bianzhou to see if there are any tributaries that can be used."

Yan Liben found the Bianzhou Water Network terrain map in three steps.

The water net near Bianzhou reflects the daily supply and demand of Bianzhou, and there is no river that can be used.

When Li Yuanai gave up, he suddenly found a northward riverbed at the corner of the map, which was sank into the map, and hurriedly said, "Hurry, take the map above. What kind of water is this? Look at the tiny river channel flowing into Si Shui."

Yan Liben took the water net terrain map again and spread it above the table.

Li Yuanai compared the rough plan and moved up the riverbed trail first, and suddenly stopped: the river was actually Luoshui.

The Luo River flows all the way to the southeast, flows into the Si River, and then goes straight from the Si River to the sea.

Li Yuanai's eyes became brighter and brighter, and the Luo River flowed into the Si River and then into the sea.

In other words, if the Luo River is diverted downstream, the downstream Sishui will not be affected in any way.

By guiding Luo River into Bian, this method can perfectly solve the current situation of the Bian River, and it can ensure the smooth flow of the Bian River without building a sluice dam.

"What do you think about it when you lead Luo River into Bian?"
