Although as the chief general of the army, Lan Yu does not need to lead the charge to fight the enemy, Lan Yu has been practicing martial arts and has never stopped.

In just half an hour, he dug a trench two feet long and six feet deep.

"Well done, old man. Is your mud repaired? ”

Zhu Ying approved with satisfaction and asked Zhu Yuanzhang next to him.

"Soon it will be ready."

Zhu Yuanzhang replied impatiently.

Although he became emperor, he did not lose his skills as a tenant farmer for him.

Sesame little things like this.

It's simple.

"It's already done."

"Well done. Now you can help me pull the concrete to the edge of the ditch. I'll be useful later. ”

Zhu Ying said to the two people beside him.

"Is this concrete? How can I feel that it is too similar to ternary composite soil, that is, the clay inside is replaced by stone. Is it really that magical? ”

Luo Furen was beside him, pulling the cement and whispering in a low voice.

Coming to the edge of the ditch, Zhu Ying instructed Lan Yu to pave the bottom of the ditch with a large stone picked up from the outside.

Then Zhu Ying inserted the wooden sign that had just been prepared vertically into the gap between the stones.

"With reinforced concrete, this is the real reinforced concrete. However, I don't have any rebar here, so I'll replace it with these wooden tags, but it works great too. ”

Zhu Ying inserted the wooden sign and explained to the person next to him.

Before Zhu Ying's crossing, some remote places still used bamboo sticks and sticks instead of steel bars to build houses.

As long as we are not unlucky, the problem is not very big.

After sticking all the sticks in his hands, Zhu Ying instructed the people to pour all the concrete into the ditch.

After about two feet are filled, continue to lay stones along the gaps in the bamboo sticks, and then continue pouring concrete.

After several repetitions, the entire ditch was filled with concrete.

"It's done now. This is the rough version. ”

Zhu Ying patted the dust off her body, and then looked at her masterpiece proudly.

Although the reinforced concrete dam is a bit rough, not only the surface is potholed and ugly, but there is also a suspicion of cutting corners inside, but the main effect is still good.

A dam built with more than just these stones and triple soil is much stronger.

"What are you telling me?"

"You say the dam has already been built?!"

Hearing Zhu Ying say this, Luo Furen next to him almost didn't jump.

He has presided over the construction of many dams and has a wealth of experience.

In such a short period of time, let alone the construction of a dam of this scale, I am afraid that even the bricks have not been built.

"How long will it take for this thing to solidify completely?"

Luo Furen took a deep breath and forced himself to calm down.

"It depends!"

"Different places, different times, different materials, different times of time."

"According to the current situation, it will only take about two or three days. If it were in the north, it would have taken a little longer, but it would not have lasted more than a week. ”

"However, this son's production is naturally extraordinary, and these in front of me have been solidified for about half a day, before dark."

Zhu Ying thought about it and answered truthfully.

"What?"

Rao is Lao Luo, who has been mentally prepared, couldn't help but be surprised when he heard Zhu Ying say that it could solidify before dark.

Changing to the previous method, let alone solidifying, I'm afraid that the materials are not ready.

The use of the two materials and the solidification time are simply the same as heaven and earth!

"How the hell is this going on?"

Lao Luo's voice trembled when he spoke at this time.

"Science!"

Zhu Ying smiled faintly, this thing actually has no technical content, but if you really want to explain it to the ancients of the Ming Dynasty, it is not clear in a few words.

"Okay, you don't have to be around here, it won't freeze for a while."

"It's been a busy day for most of the day, and everyone is hungry, right?"

"Take advantage of this time to cook! By the way, rub it twice! ”

Zhu Ying touched her stomach, she didn't stop when she got up early in the morning, and she was indeed a little hungry until now.

"What are you rubbing? What are you cooking? I'm not going anywhere! I'll just stay here and watch it freeze! ”

"At such an important moment, you are still in the mood to cook?"

"I'm mad at me!"

Seeing that Zhu Ying proposed to play mahjong, Lao Luo went straight away!

Seeing that Lao Luo's oil and salt did not enter, Zhu Yuanzhang and the others were embarrassed to go, so they had to let Zhu Ying get some food casually, and a group of people gathered around Lao Luo, eating and waiting.

Luo Furen stood quietly beside the reinforced concrete dam, waiting for the dam to fully solidify, touching the main body of the dam from time to time.

It looks like a neuropathy.

"Alright, it's almost done."

Hearing Zhu Ying's words, Luo Furen laughed wildly.

Before the sun goes down, the reinforced concrete is poured into the dam and eventually completely solidifies.

"Let me try how hard the dam is. You smashed it with all your might. ”

"You can rest assured."

Luo Furen took an iron rod from his body, placed it on the main body of the dam, and then handed the hammer to Lan Yu.

Sapphire struggled to raise the hammer, then slammed it down.

Bang!

There was a loud bang, and sparks splashed onto the dam.

People polish their eyes and see that there is only a small white dot on the main body of the dam, and the rest of the dam is in good condition. Not even the mud chips came off.

Luo Furen and Lan Yu changed places on the main body of the dam and tried many times, but the result was still the same.

"From today, there will be no more floods in the Ming Dynasty."

Luo Furen stroked the main body of the dam with trembling hands, praising it frantically.

When he turned around, two lines of clear tears slid down his cheeks.

"Zhu Gongzi, on behalf of the Ming Dynasty, I would like to thank you for your eternal kindness."

Luo Furen took a deep breath, tidied up his appearance, and bowed respectfully to Zhu Ying.

This was to thank him for his contribution to the Ming Dynasty.

Since ancient times, Yan Huang has been most afraid of floods.

Every time there is a flood, there are thousands of hungry people, wailing everywhere.

But now with reinforced concrete, although it is not guaranteed that it will solve all the floods of the Ming Dynasty, it will reduce the consequences of floods by a thousand times.

Based on this, Zhu Ying can be said to have made great achievements.

"Well, you can. This little bastard finally got it right. ”

Zhu Yuanzhang nodded with satisfaction.

Liu Bowen was taken aback.

Since ancient times, humans have not been able to resist the forces of nature.

Because of this, it was enough for the emperor and his grandson to leave a name in history.

Lan Yu was excited by his side.

The reinforced concrete invented by the emperor's eldest grandson could not only build fortresses, but also dams.

What the hell is this?

The Emperor's eldest grandson is a treasure, and it seems that I must walk around with him more to see if I can get any benefit from him.
