"No, what's wrong?" Pei Beiyin's pleasant voice sounded in the quiet night.

"I can't sleep, please reach out your hand." Zhou Jian stretched out his hand and passed it through the curtain.

Pei Beiyin hesitated for a moment, then looked at Zhou Jian's hand. Perhaps the night and space gave her a sense of security, and she mustered up the courage to slowly stretch out her jade hand.

Zhou Jian held it directly, as if holding mutton-fat jade.

Pei Beiyin trembled, but did not refuse.

Under the moonlight, the two of them intertwined their hands and were extremely quiet. No one spoke, but they were enjoying the beauty and tranquility of this moment.

The next day.

Pei Beiyin woke up early in the morning and prepared hot water and everything for Zhou Jian, as skillfully as a wife.

When she walked out of the tent, Master Ku and others looked at her as if they were looking at the empress. She stopped correcting her and gradually became clear about her feelings.

"Report!!"

"Your Majesty, the five hundred windmills have been completed. Please inspect them!" Qiao Liang, the minister of the Ministry of Industry, rushed over with dust all over his body, extremely excited.

Zhou Jian stood up suddenly when he heard this, and then frowned: "Why are there only five hundred units? This is too little."

He passed a budget and found that at least 2,000 units would be needed to divert the water.

"Your Majesty, I have been working on it all night, which is the limit, but I can keep up with the follow-up. Once these five hundred units are installed, they will follow, and there will be no delay." Qiao Liang handed over.

"Let's go take a look!" Zhou Jian rushed out without saying a word.

"yes!"

Pei Beiyin wrung out the handkerchief for him, and then he ran away. She didn't even wash her face, so she quickly followed him.

The group of people came to the open space in the Changhe River Basin, where there were 500 ancient windmill devices neatly placed. They looked brand new and smelled of oak.

Zhou Jian looked at it intently and kept touching it, just like looking at a beautiful woman taking off her clothes. If nothing happens, the irrigation problem will be easily solved!

He shouted: "Quick, quickly push it into the dug trench and fix it, and start trying to divert water!"

"Yes!" Everyone clasped their fists, and the Forbidden Army moved quickly, carrying the windmill device into the trench dug in advance, and fixed it with stones.

Maybe God saw everyone's efforts and was very lucky when a strong wind came, causing the river to be blown by sand and rocks for a while.

Zhou Jian was excited: "Back off, back off, back off!!"

The sound was deafening. Thousands of people heard the words and quickly retreated. Everyone stared at this novel windmill device, full of expectation and urgency.

"Can this really divert water?"

"Of course, I believe it, Your Majesty!"

Just like that, under the gaze of everyone, the fan blades on the series of windmill devices began to rotate slowly under the influence of the wind.

Its principle is very simple, it is powered by wind, and after the fan blades rotate, they rely on the weight of the water itself to continuously press down, driving the device to rotate continuously.

Theoretically, as long as the wind does not stop and the water does not stop, the windmill device can keep running, allowing water to be transported continuously.

It can be said that this is the great wisdom of the ancient Han people. It can be called the first invention of the Great Zhou Dynasty!

Pei Beiyin's jade hand was already sweating, and his other hand even subconsciously grabbed Zhou Jian's clothes, nervous.

Huhuhu...

The strong wind roared, and the blades of the windmill device rotated faster and faster.

Sudden!

Wow...
Chapter completed!
