Several strong men carried seven or eight stones and bet them on both ends of the ship.

"My lord, how can you take risks with your golden body, let Chang Feng go for you!" Chang Feng stopped in front of him and said seriously.

"This official has excellent water quality, and there will be no accidents, you just wait here, and then I will find out the gap, and then discuss how to deal with it." Li Canghai said as he jumped on the boat.

Chang Feng panicked and said eagerly: "My lord, if you have to go on an adventure, then let Chang Feng go with you!" ”

Li Canghai propped up the oars, and he was just about to paddle when Xiao Wu suddenly jumped up.

"My lord, Xiao Wu is quite good at water, so let Xiao Wu accompany you!"

Li Canghai looked at Xiao Wu's firm eyes, hesitated, nodded and said, "Since that's the case, you can go with me." ”

The two rowed a small boat and slowly walked towards the breach of the Yellow River.

Chang Feng and the others stared at the boat intently, their faces were very solemn, for fear that a big wave would hit and directly overturn the boat.

The Yellow River is about two or three miles away from the Longwang Temple, but the water depth is a few feet, and the water is turbulent, it is simply a boat against the current, not advancing but retreating.

The two rowed the boat with great difficulty, and circled around the water in place a few times, Li Canghai felt that this was too difficult, so he decided to directly avoid the breach and approach from the side.

Facing the breach, it is bound to face the impact of the water velocity head-on, while the impact on the side is weaker.

Although it made a big circle, the effect was not bad, and the boat finally slowly approached the breach.

Approaching the breach, the two men threw down the two stones that had been tied to the boat in advance, and the stones were tied to the strings of the boat, and the rope was tied to the string at one end, and the two boulders fell heavily, and the hull of the ship swirled back and forth in the water, but it was not washed away.

The water flow at the breach was too turbulent for the boat to approach at all, so Li Canghai could only stop the boat more than ten zhang away from the breach to observe.

The Yellow River has always been prone to flooding, so since ancient times, successive dynasties have built dikes along the Yellow River.

The embankment in front of him was built during Li Shimin's reign, and was later strengthened by Wu Zetian, and the embankment was already five zhang high.

However, the water level of the Yellow River soared, causing a huge impact on the embankment, which caused one section to be washed out of the breach.

After observing the breach at close range, Li Canghai realized that if he wanted to block the breach, it was simply difficult to climb to the sky.

The water level of the Yellow River rises to almost the same height as the dike, and the river is blocked by the dike, and this is the only point of impact.

The low terrain of this execution, coupled with the violent impact of the river, made the breach bigger and bigger, and it was already twenty zhang wide by sight.

Li Canghai stood in the boat, and he could feel the huge impact of the embankment being hit by the raging waves, as if the embankment would collapse at any time.

If this section of the embankment is completely destroyed, Zhengyang City will bear the brunt of the flood.

Thinking of the tens of thousands of people in the city, Li Canghai's expression became more and more solemn.

He looked at the turbid water of the Yellow River, constantly impacting the breach, and a depression that had never existed before arose.

Wow~!

The surging water slammed against the dike, causing a wave to rise a very high pitch, and the turbid water went directly over the dike, slapping on the boat.

The boat was suddenly swayed from side to side.

"My lord, it's too dangerous here, let's leave first!" Xiao Wu was worried about Li Canghai's safety and said eagerly.

Li Canghai already understood the situation at the duel, so he didn't stay any longer, rowed a boat with Xiao Wu, and returned to the Dragon King Temple.

"Are you okay, sir?" Before the boat docked, Chang Feng hurriedly met it.

Li Canghai got off the boat and said solemnly: "I'm fine, but the situation at the breach is far more serious than I imagined." ”

Then, Li Canghai told what he had seen.

"If the embankment is broken through the whole section, Zhengyang County will instantly become Zeguo, and the breach must be blocked as soon as possible, otherwise the consequences will be unimaginable!" After listening to Li Canghai's description, Zuo Hongji groaned.

"My lord, let's ask the court for help!" Chang Feng knew that the situation was serious, and hurriedly proposed.

Li Canghai said solemnly: "I have already submitted this matter to Luoyang Mansion, but I am afraid that the actions of the imperial court will not be so fast, and the flood will not wait for the imperial court to send talents to flood." For now, all we can rely on is ourselves. ”

Several people were stunned for a moment, they looked at each other for a while, and Chang Feng smiled bitterly: "My lord, where are we going to get so many stones to plug the leakage now!" ”

Li Canghai's brows furrowed, he turned to look at the lonely mountain behind him, and then looked at the stones piled up in front of the temple, and suddenly a flash of inspiration came of mind, and he thought of a way.

"Chang Feng, go get me some gravel, dirt, lime powder, I'm going to do an experiment."

Chang Feng did not hesitate to Li Canghai's order, and immediately after receiving the order, he went to prepare those things.

Zuo Hongji didn't understand what a test was, and he wondered, "My lord, what do you want to do with this?" ”

Li Canghai said inscrutablely: "I once met an old Taoist priest and learned some spells from him, maybe he may be able to block the break." However, I don't know if this spell will work or not, and I can only know if I try it. ”

Zuo Hongji was surprised, he glanced at the break in the distance, and his heart beat a drum, such a big gap, even if the Dragon King appeared, I'm afraid it would be difficult to plug it, right?

However, seeing that Li Canghai was confident, he suddenly looked forward to it.

After about a quarter of an hour, Chang Feng prepared all the things he commanded.

Li Canghai poured lime powder, gravel and soil into them in different proportions, then poured water into the shallow pits, and stirred them with wooden sticks.

After all the shallow pits were completely homogeneous with lime powder, gravel, and soil, Li Canghai began to observe.

He crouched down on the edge of the shallow pits, wrote down the proportions of the recipe, and then performed the math on the ground.

Everyone was confused, but it was not good to disturb him, so they could only wait on the sidelines.

They didn't know that Li Canghai's so-called spell was actually to make a simple concrete.

The breach of the Yellow River is too large, and it is urgent to plug the leak as soon as possible. The nearest mountain rich in stones is Bishan, which is difficult to walk on mountain roads, and it is difficult to quarry, so it is simply far away from water to quench the thirst of the near.

Li Canghai had a flash of inspiration, and at that time he thought about whether it was possible to make a simple concrete instead of stone to plug the leak.

It's a bold idea, one might even say a gamble.

If his method worked, Zhengyang City would be able to avoid being flooded.

On the contrary, if his method is not feasible, the fate of Zhengyang City will be in jeopardy. All he could do was to personally lead the people of the county to flee.
