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

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

Pei Beiyin hesitated for a moment, looked at Zhou Jian's hand, perhaps the darkness and space gave her a sense of security, and plucked up the courage to slowly stretch out her jade hand.

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

Pei Beiyin trembled, but did not refuse.

The moonlight was bright, the two of them had their hands connected, and they were extremely quiet. No one spoke, but they were enjoying the beauty and tranquility of this moment.

The next day.

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

When she walked out of the tent, Master Ku and others looked at her like they were looking at the empress. She no longer corrected this and gradually became clear about her heart.

"Report!!"

"Your Majesty, the five hundred windmill installation has been completed. Please check it out!" Qiao Liang, the Minister of Works, rushed over with dust, and was extremely excited.

Zhou Jian stood up suddenly when he heard this, and then frowned: "Why are there only 500 units? This is too few."

He had a budget and needed at least two thousand units to lead the water over.

"It's the limit to your Majesty, it's already the limit to rush to make it overnight, but you can keep up with it later. Once these five hundred units are installed, they will come afterwards and will not waste time." Qiao Liang bowed.

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

"yes!"

Pei Beiyin wrung the veil for him, and then ran away. Before her face was washed, she quickly followed.

The group came to the open space in the Changhe River Basin, where five hundred ancient versions of windmill installations were neatly placed, which looked brand new and exuded an oak fragrance.

Zhou Jian looked at it tightly and kept stroking it, just like watching a beautiful woman taking off her clothes. If nothing unexpected happens, the problem of irrigation will be solved!

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

"Yes!" Everyone clasped their fists, the imperial guards acted quickly, carried the windmill device and entered the ditches dug in advance, fixed them with stones.

Perhaps God saw everyone's efforts and gave him a strong gust of wind and windy and sand and stones were storms by the river for a while.

Zhou Jian was excited: "Go back, back, back!!"

The sound was deafening, and thousands of people quickly retreated when they heard this, staring at the novel windmill device one by one, full of expectations and urgency.

“Can this really draw water?”

"It is certainly possible, believe in your Majesty!"

In this way, under the attention of everyone, the fan blades on the windmill devices began to rotate slowly under the action of wind power.

Its principle is very simple. It is to rely on wind power to start. After the fan blades rotate, it will continue to press down based on the weight of the water itself to drive the device to rotate continuously.

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

It can be said that this is the most powerful wisdom of the ancient Han people. After being in the Great Zhou Dynasty, it was the first invention!

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

Huhuhuhuhu...

The wind is howling, and the fan blades of the windmill device are rotating faster and faster.

Sudden!

Crazy...
