Transmigrated into a female county magistrate during a famine, leading her country to prosperity

Drops of sweat dripped from Shen Zheng's forehead. Hua Duo felt distressed watching this but was unable to help. He could only take out his handkerchief to wipe the sweat off her face again and again.

The three of them stopped talking, and the cicadas chirped louder and louder. At this moment, a voice broke the silence.

"The old man is coming!"

Lin Fanyun was the first to turn around and saw that the person who came was a stranger, a thin old man, followed by a young man with dark skin, holding the horse's reins.

He looked at Shen Zheng again.

"You're finally here." Shen Zheng wiped the sweat off his face and stood up, stretched out his hand and asked, "Where's the stuff?"

Old Qiao also wiped his sweat and pointed at the carriage road: "It's on the carriage. Let the old man take a break. We will load it together later. After loading, this day will not be so hard to endure."

Lin Fanyun was confused by what he heard and could not help but look at the things on the car - the bamboo bones were woven into half leaves, which were then put into palms, and the palms were interlocked to form a wheel.

Another thing he had never seen before.

He couldn't help but ask: "Master Shen, what is this...?"

It was too troublesome to explain, so Shen Zheng thought for a moment and said, "When Mr. Qiao is done pretending, General Lin will know."

"Mr. Qiao?" Lin Fanyun was slightly surprised and looked at Mr. Qiao: "Is this the craftsman Qiao who made the textile machine with you? And the wheelchair that has been popular in Beijing recently..."

Recently, the fifth patriarch has been moving around in a wheelchair, and many dignitaries in the capital are saying that the craftsman brought by Lord Shen is a master craftsman.

"The old man only knows how to fight." After drinking the water, Old Qiao stood up and said, "The methods are all from Lady Shen. Wherever she points, the old man will fight."

After saying that, he walked past Lin Fanyun and took the things down from the car.

"Are you satisfied?" he asked Shen Zheng.

Shen Zheng pinched the fan blades and nodded, "Yes, if the palm leaf cover is unfolded, the wind force should be quite strong after it is installed."

Old Qiao chuckled, "What are you waiting for? Let's get started!"

The two of them started working right away. Hua Duo and Cheng Yu helped, while Lin Fanyun stood aside, feeling quite redundant.

Time passed quietly, and before they knew it, it was noon. The sun was high in the sky, but the few of them had not finished their work yet.

Looking at the installed fan, Shen Zheng walked to the diversion channel and thought about the next steps.

"Connect the water wheel shaft, put the driving disc into the canal flow, add two sandbags, connect the driven disc with a rope, and it should be able to operate."

Old Qiao stood beside her, stroking his chin, as if thinking about something.

After a while, his eyes lit up and he asked, "If we replace the water power with human power, can we make the fan rotate?"

After saying that, he squatted down, touched the driven disk, and looked left and right.

"Put a foot pedal or hand pull rope on the driven disc and drive it with manpower, and you can use a fan in the room!"

Seeing how cheerful Mr. Qiao was, Shen Zheng suddenly laughed, "I thought it would take you two days to remember it."

Hearing this, Old Qiao stood up with his eyes wide open, "So you already knew about this?"

Shen Zheng smiled and said nothing.

When she first started studying fans, she was attracted by the energy of nature.

——Convert the kinetic energy of water flow or wind into mechanical energy, and then use the mechanical energy to drive the fan.

As for human-powered power...it was not within her consideration at first, but the human-powered fan, which came out in the Great Zhou Dynasty, can actually be regarded as a technological advancement.

After the water-powered fan on the dam is completed, Mr. Qiao can be asked to manufacture a human-powered fan. By then, Mr. Qiao's reputation in Beijing will naturally rise.

As he was thinking, Zeng Tongshi came over with sweat all over his forehead.

He glanced at the fan curiously, then looked away and said, "Master Shen, the kitchen has prepared lunch, let's eat first."

Lin Fanyun had not been able to get a word in before, but after hearing this, he quickly agreed: "Master Zeng is right. Master Shen, there is always work to be done. No matter how busy you are, you must not forget to eat, okay? Women's bodies are different from men's..."

"Eat, eat, eat." Old Qiao sat down between the two of them and pushed Shen Zheng towards the kitchen.

Seeing Lin Fanyun being left behind, he whispered, "Is this the annoying brother Nan Shu was talking about? Really, he was watching from the side the whole time and made me install the bearings incorrectly twice!"

Shen Zheng smiled without saying anything, and led him and Cheng Yu into the kitchen.

Seeing her coming, the head chef smiled widely and hurriedly introduced today's dishes to her.

Old Qiao originally thought that Shen Zheng was living a hard life on the dam, but after listening to Cantou's introduction, he couldn't help drooling.

"I was wondering why you haven't lost weight these days on the dam. I guess you've been cooking for yourself every day..."

......

After dinner, Old Qiao held his waist and followed Shen Zheng to the diversion channel. Lin Fanyun had no intention of leaving and followed the two closely.

Huaduo easily placed the basin-sized active disc into the diversion channel. Starting from the edge of the channel, there was an iron guide pulley every ten steps, extending all the way to the center of the dam.

The workers' attention was inevitably drawn over. Zeng Tongshi and several other officials also came over and looked at them curiously, but did not make any noise to disturb them.

Shen Zheng held the rope in his hand, and under the gaze of everyone, he fixed the rope to the driven disc, then turned around and called out, "Mr. Qiao, pull the main rope!"

Everyone looked at Mr. Qiao, only to see him grab the rope by the canal and pull it hard. Suddenly, all the pulleys on the dam started moving.

This movement stunned many people.

But when I pulled the rope beside the canal, how come all the wheels on the dam started moving?

It’s like being cast under a spell by a god!

Lin Fanyun was puzzled and asked Shen Zheng directly: "Master Shen, Mr. Qiao just pulled the rope, why are these iron wheels......"

Before he could finish his words, he watched the strange object opposite him suddenly start to spin.

But in the blink of an eye, the thing spun faster and faster, and by the time he reacted, his hair was already flying.

"Wind...?" His expression was out of control for a moment, "This thing can actually produce wind on its own?"

How much wind there is and which direction it blows all depends on God's mood, doesn't it?

Even if you don't care about God's mood, don't you still have to fan yourself?

How come this thing in front of me can rotate by itself and create such a strong wind?

Lin Fanyun touched his forehead and looked at the sun with a halo above his head.

"I must have heat stroke..."

In a trance, he saw Zeng Tongshi also touching his forehead, and then shook his head and asked Shen Zheng: "Master Shen, this, this is... the water flow in the diversion channel, bringing us wind?"

Shen Zheng was feeling the wind with her palms and was slightly surprised when she heard this: "Master Zeng is really amazing. He immediately figured out the principle of this fan."

"Fan?" Zeng Tongshi looked at the fan that was rotating by itself and suddenly realized: "A fan that blows air by itself can be called a fan! But Lord Shen, this is too amazing... This place is dozens of steps away from the diversion channel, and it can actually use the force of the channel to do it?"
