In history, this heavy rain caused waterlogging in many places near Chang'an.

It rained for five days, and Li Shimin came to Jingyang again to ask whether Li Zheng Tuyuhun would attack.

It was really scary to predict this heavy rain. I came here to confirm it again this time.

Li Shimin also dressed up as an ordinary family with a hat, and Fang Xuanling followed him all the way.

Li Junxian followed, not sure why His Majesty came out in the rain. The weather was warm and cold. What should I do if I got sick after being infected with the wind and cold.

When you walk towards Jingyang County, you can see from a distance that many villagers are building river embankments here.

The water system near Chang'an is well developed, and it is known that eight waters surround Chang'an. Looking at the situation, Li Shimin asked Fang Xuanling, "Are you just preventing floods?"

There have been droughts in Chang'an just in the past few years, but floods have not occurred in several years.

When Li Shimin saw Li Zheng, who was also wearing a straw hat, he stepped forward and said, "Are you asking the villagers to build a river embankment?"

"It's you again." Li Zheng turned around to see him.

Li Shimin smiled, "You said a few days ago that it will rain in Chang'an. It's really raining. How did you calculate it?"

"This is very simple. There will be some signs before it rains, such as looking at the clouds, feeling the wind, watching insects and ants, and some old farmers can also see it." Li Zheng said.

After saying this, Li Zheng was a little guilty, so he should be able to fool him.

After hearing what Li Zheng said, Li Shimin smiled and didn't believe it very much. Some old farmers could indeed see some signs to judge whether it would rain.

But can the old farmer predict that it will take so long for a rain?

This kid didn't tell the truth.

Li Shimin was confident.

Li Shimin asked: "You asked the villagers to build river embankments and fear floods?

Li Zheng smiled and fell silent.

"I'm asking you something." Li Shimin continued to ask.

Li Zheng cleared his throat and said, "The wind is so noisy today."

Feng? When asked about the flood, he actually said that the wind was noisy?

Looking at Li Zheng's expression, Li Shimin immediately understood and reluctantly took out a piece of silver cake, "I would like to ask my little brother for advice."

"Brother, why are you doing so politely? Am I the kind of person who is jealous of money?" Li Zheng quickly took over Yinbing.

I have seen shameless people, but I have never seen such shameless people. Li Junxian looked at Li Zheng's face and was furious and was about to draw his sword...

"Will a flood happen?" Li Shimin asked again.

Li Zheng whispered to him: "What I want to say next, don't be afraid."

Li Shimin nodded, "Please speak."

Li Zheng whispered: "Floods will be affected in Chang'an, flooding crops and flooding, resulting in poor harvests in many places."

"Really?" Li Shimin looked nervous.

"You can't say such words randomly. If they spread, the court might arrest me with insults."

"How could it be?" Li Shimin smiled awkwardly.

"Why can't you? Your Majesty is a cruel man who can't rub the sand in his eyes."

A person who can't rub the sand in his eyes? Li Shimin thought to himself that I am such a harsh person in the market?

The people are all afraid of me, so who else dares to tell the truth?

I think I open up a wide range of words, but there are a few who are not flattery, and there are a few who dare to speak the truth.

After Li Zhenggang finished speaking, he saw Li Shimin with a dark face, "Huh? Brother, why are your face dark?"

Li Shimin recovered his expression, "Why do you say there will be floods in Chang'an?"

"You see, you don't even believe it."

Li Zheng said and took him to the Jingyang River, pointing to the turbulent river surface and said, "You see, the river water is very turbid, right?"

"What's the reason?" Li Shimin was puzzled.

"The turbid river water means that there is a lot of silt in the riverbed under the water. If there is more silt, the riverbed will be higher and the space for water to flow will be smaller."

Li Shimin shook his head and said he didn't understand very well.

For the sake of his payment, Li Zheng found a puddle, threw down a stone and said, "Look at whether the water is coming up now."

"The mud in the upstream continues to wash away, and the downstream will suffer." Li Zheng said again.

After hearing Li Zheng's words, Li Shimin stared at the stone placed in the puddle and immediately understood the reason.

The more silt there is in the water, the higher the riverbed, and over the years, a lot of silt downstream has accumulated.

In fact, the Jingyang River bed has been getting higher and higher over the years, and the space for water flow will naturally overflow the river embankment if it is smaller. In addition, it is now raining heavily.

"You go upstream and take a look right now." Li Shimin ordered Li Junxian.

"But..." Li Junxian wanted to stay and protect His Majesty, but he didn't bring any guards when he came out.

"I'll tell you to go, you go." Li Shimin shouted.

Li Junxian left in panic to see the situation upstream

Li Shimin turned around and asked again: "You said Tuguhun's wolf ambitions, will Tuguhun come to attack the Tang Dynasty?"

"Yes." Li Zheng nodded.

"How can I see it?" Li Shimin asked.

Li Zheng smiled slightly and stopped talking.

Li Shimin took out another piece of silver cake.

Li Zheng calmly accepted the silver cake and said, "See if they will pay tribute to the Tang Dynasty this year. If you go to explore the Tubo behind Tuyuhun, you will understand."

Li Shimin fell silent and thought about Li Zheng's words.

Li Zheng said and left.

Li Shimin stood there and faced Fang Xuanling with four eyes.

After Li Junxian came back, he reported: "Your Majesty, there are many places upstream that have already shown signs of river water flowing back. It's good now, but if the rain is still falling, I'm afraid it's..."

Li Shimin looked at the two sides of the river, and the farmers in Chang'an always surrounded the lake to build fields, and all the food was planted by the river.

If the river water is poured back, how much food will be affected.

Li Shimin hurried back to Chang'an and came to the palace and immediately asked someone to investigate the river situation.

After some investigation, as Li Zheng said, not only Jingyang but also the Wei River, Bashang Bashui, and Wushui...

These rivers are surrounded by counties with a large population.

Li Shimin immediately issued an edict to build river embankments for dozens of miles around Chang'an to prevent floods.

Chang'an City is also prepared for drainage to avoid flooding.

Dozens of officials and officers rode their horses away from Chang'an with their hats and headed towards all sides.

Changsun Wuji knew about this, would there be flooding in Chang'an?

It would be no wonder if it was rainy in summer.

But now it’s just spring, and there won’t be so much rain. Even if it rains, the rain will stop in a few days.

"Your Majesty, you shouldn't be so busy." Changsun Wuji sighed: "How much manpower should be used to build the river embankment? The rivers around Chang'an are thousands of miles long. Your Majesty is a bit too much. It's the wind and rain."

"Duke Zhao means..." Several county officials asked Changsun Wuji.

These county officials are all county officials with fiefs of the Changsun family. The Changsun family is their biggest landlord. Although they are considered court officials, they also involve their own territory. It depends on the Changsun family's expression.

Changsun Wuji whispered: "Although Your Majesty wants to build a river embankment, you can do it, but don't work too hard to mobilize the troops."
