"Yes." Wei Zhigu woke up. Why should I be sad? The Ministry of Industry has questions to ask Li Yi.

I, the minister, came here today just to listen to what you said. As long as you ask, Li Yi will definitely give you a good solution.

So if you are in trouble, ask a petty official to accompany you, and I hope you will be magical again.

"Block the breach?" Li Yi was no longer in the mood to show off with poems, and the real thing was coming.

"Yes, the water was strong and the river burst. After spring started this year, several small holes opened in the Yellow River. People died. It took a lot of efforts to block it."

Zheng Guang explained the situation and glanced at Li Longji from time to time.

The Ministry of Public Security did not report this incident because the number of deaths was only a few hundred or so.

Li Longji immediately looked at Wei Zhigu and shook his head.

The opening of the Yellow River happened before May, and Wei Zhigu had been at the Ministry of Industry for less than a month, so it had nothing to do with him.

Li Yi lowered his head and pondered, blocking the matter...

Does it count if PLA soldiers jump holding hands?

Replaced with Tang Dynasty soldiers.

Obviously not, if you say it, this little official will be bitten to death.

"Dr. Li, didn't you say that every question must be answered? Please hurry up." Zhang said anxiously.

He also knows that water conservancy is difficult to control. At this critical moment, you, Li Yi, are so awesome. Both His Majesty and Prime Minister Yao have come to ask you for political advice.

Li Chengqi glared at Zhang and said, "Stop talking."

"You..." Zhang said he was about to retaliate, but when he saw His Majesty looking over with dissatisfaction, he had to hold back.

"Alas!" Li Yi sighed: "To be honest, the Yellow River burst because the angle of the river is too large, especially the nine and eighteen turns."

"Yes." Zheng Guang was confident. At least this person knows the nine turns and eighteen turns.

"The other two reasons are the river opening period and the late river opening period."

"The river opening period is when the river opens upstream, the downstream is frozen, the ice blocks the bank, and the upstream is overflowing with water."

"The second is the accumulation of sand in the river, which causes the water level to rise. Later, the water encounters obstruction and overflows."

Li Yi said the reason was the Yellow River.

"Yes, yes, Dongzhu Li, that's exactly it." Zheng Guang was confident.

Li Yi continued: "To control the river, we must treat the root cause, use the river to control the river, and use water to attack the sand. As for the ice period, we can explode."

"How can we use rivers to control rivers and water to attack sand? What is explosion?" Zheng Guang became even more anxious and wanted to explain clearly.

Li Longji's eyes lit up, Brother Yi clearly had a solution.

"Let's not talk about anything else. Let's talk about blocking the breach." Li Yi changed the topic back.

He added: "Blocking the breach is nothing more than throwing things. Throwing things into the river where the breach occurred. Throwing sacks of earth and rocks is throwing. Throwing stones is also throwing."

"But as soon as I threw it down, the current was strong and the things were washed away. We must first find a way to prevent the things from being washed away, right?"

"Yes, yes. Tell me quickly." Zheng Guang wanted to open Li Yi's head and find a solution.

"There is something called a willow roller. The dimensions...just follow the textbook. It is fifteen feet long, not counting the width."

"Weave branches, grass and soil into a blanket. After rolling it up, it will be two feet in diameter. Take a big piece of wood and roll it in the middle, and tie it tightly with a rope."

"Throw it into the water, tie a rope behind it, and pull it. When it encounters blisters, it will expand and become larger. It is useful for blocking breaches."

Li Yi gave me something, a willow roller.

As everyone listened, Li Chengqi shouted to the attendant who was dozens of steps away from them: "Bring over the pen, ink, paper and inkstone."

The people over there sprinted over and did some operations. Zhang said he wrote it himself.

Write a paragraph and ask again, as detailed as possible, so that people will know what to do at a glance.

After finishing writing about the production and application of willow rollers, Zhang said and raised his head: "Is there anything more?"

"Yes." Li Yi said.

"Speak quickly." Wei Zhigu urged.

At this moment, he was convinced. Sure enough, if you have any questions, just ask. No wonder His Majesty always comes over, and he comes often when he has time.

This Li Yi is so amazing that he didn't tell anyone when he came.

As a result...if you ask about the issue of the wound, there will be a cure for the issue.

He's so strong that it's unreasonable. Why don't you take him to the Ministry of Industry?

Thinking this way, Wei Zhigu couldn't hold back and said directly: "Dongzhu Li, I think you can join the Ministry of Industry as an official, starting with the sixth rank, not the fifth rank, and the fifth rank can go to court."

Well, four eyes swept over at the same time, with murderous intent. One of them had the strongest murderous intent, His Majesty's.

Queen Wang glanced at Wei Zhigu and said, "My uncle wants to be the prime minister."

She was angry, so she stabbed Wei Zhigu, and Wei Zhigu was dismissed as prime minister.

"Yes." Li Longji added another blow.

Wei Zhigu: "..."

I am not angry. I have been prime minister after all, so I have offended Yao Chong. I have a clear conscience. I cannot help his two sons do bad things.

Zheng Guang glanced at them and said to himself, please consider my feelings. You should start with level 5 so that you can go to court.

Then His Majesty and the Queen are not happy anymore, what are you going to do? It's very hard for me too, I can't even go to court.

Zhang said he didn’t want to read it, it was boring, what a prime minister, isn’t he now the foreign minister?

Li Yi took a few glances and felt that the emotions were quite complicated.

Said: "Another method is to build a slope and load the wooden cart with stones, and then use a rope to connect it. Use the willow roller at the same time."

As Li Yi spoke, he picked up another piece of paper, moved his pen, and drew simple diagrams of earth-shattering and broken-down cars that almost didn't take long at all.

"This cart doesn't need to be very strong. It needs to be used in conjunction. A bunch of carts can be connected in a row at a time. The cart doesn't need to be made of good wooden boards. It can be braided with rattan and broken wood."

"The wheel is difficult to cut, so I... better use a trough, smear it with soybean oil, and push or pry it to move."

Zhang said reaching out and taking away the paper Li Yi drew.

"Give it to Zheng Yuanwailang, what are you going to do with it?" Li Chengqi reminded.

"Let me take a look." Zhang said and gave the reason.

He glanced at it casually: "Here you are... Zheng Yuanwailang."

"Okay, thank you." Zheng Guang took it and looked at it first, then folded it up and put it into his arms along with the writing paper.

"Master Zheng, please go back quickly." Li Chengqi said again.

"What about... using rivers to control rivers, water to attack sand and bombing?" Zheng Guang still wanted.

He knew that blocking the breach was a temporary solution, while the other was a permanent solution.

Li Yi said: "Building embankments to block them and confining water to attack sand, combined with continuous embankments and remote embankments, require more text introduction, and there is a lot of content. They are mainly used in water diversion and flood control areas."

He didn't want to write so many words today. He was tired and couldn't calm down.

As for exploding ice, which involved fixed-point blasting technology, he had to get gunpowder first, and ordinary gunpowder would not work.

Zheng Guang understood, looked at a few people with regret, and went to find a horse outside the village to ride back. He wanted to quickly copy out the things and hand them over.

After he walked a few hundred steps, Song De, the steward, caught up with him and gave him a backpack-like box for scholars.

Inside were two pounds of soy sauce, a jar of fermented bean curd, a jar of stinky tofu, and a large bag of Qixiang.

Zheng Guang was not polite, thanked him and looked for a horse on his back.

Wei Zhigu sighed, finally, he had made political achievements as Minister of the Ministry of Industry.

It's a pity that his political achievements can only be told to the people by the river and in the court.

If I have to say that I have some merit, it can only be that I brought a member of the Ministry of Water Resources to find Li Yiwen.

Zhang said, look at Li Yi, and then expressed admiration to Li Longji: Your Majesty is really powerful. We didn't know he was so capable.

Li Longji is happy, what's wrong with me wandering around the palace? I have official business, not just for fun. I haven't been to the Liyuan for five days.

If you have many solutions, why do you need me to come out personally? Who knows the pain in my heart? It is not easy for me.

As the inner drama was playing out, Li Longji got into the act and was so moved that his eyes were red.
