Primordial Era: Mistakenly Taking Emperor Xin as Father, Nuwa is Destroyed at the Start

Li Xuan pointed to one of them.

"This is called a waterwheel! It uses the power of water flow to lift water from lower elevations to irrigate farmland!"

He then pointed to another one.

"This is called an open channel! It involves digging ditches and canals to divert water from rivers and lakes to where it's needed!"

He patted the blueprints, his tone carrying an air of self-assured confidence.

"With these things, why should we depend on those damn gods for rain? We can irrigate our fields ourselves! I can't guarantee a harvest regardless of drought or flood, but at least we can survive and grow food!"

Li Xuan explained.

Di Xin, Huang Feihu, and Su Daji all crowded around to look at the two animal hide drawings.

Waterwheel? Open channel?

The things drawn on the drawings look quite complex in structure, but they are all drawn with charcoal sticks, and the lines are rough, like random doodles.

Di Xin frowned, pointed at the waterwheel diagram, and asked, "Xuan'er, this...this thing really works? Can these wooden planks really lift water from a low place to a high place?"

Huang Feihu also looked suspicious: "Yes, Brother Li, this doesn't seem to have any magical fluctuations... How can it compare to a celestial being casting a spell?"

Although Su Daji didn't understand these things, she still felt that relying solely on a wooden frame to draw water was a bit of a fantasy.

Li Xuan laughed when he saw their expressions.

"Hey, I knew you wouldn't believe me! You can't just look at blueprints, can you?"

He stood up and dusted off his bottom.

"Come on, let me show you around the backyard. Perfect timing, I have a finished sample there, let me show you!"

After saying that, Li Xuan led the way to the backyard.

Di Xin, Huang Feihu, and Su Daji exchanged glances and quickly followed.

The backyard was more dilapidated than the front yard, with some miscellaneous items piled up in the corner.

Li Xuan walked to a place near the water, where a strange device made of wood and bamboo stood.

The main body of the device was a large wheel with small wooden planks inserted diagonally along its edge. A foot pedal was connected to an axle in the middle of the wheel, and the bottom of the wheel was submerged in a small ditch. Several bamboo tubes were attached to the side of the wheel.

"Here it is, a waterwheel." Li Xuan patted the wooden frame. "Looks simple, right?"

Di Xin and Huang Feihu circled the waterwheel twice, looking at it from left to right, but still couldn't figure out what it was.

"This...can it really work?" Huang Feihu couldn't help but ask again.

"Whether it works or not, we'll find out by trying!"

As Li Xuan spoke, he stepped onto the foot pedal next to the waterwheel.

He pushed off with all his might.

Squeak...

The wooden wheel began to turn, causing the small wooden planks along its edge to glide across the water's surface in sequence.

Something amazing happened!

As the small wooden planks skimmed across the water, they scooped up a small handful of water.

As the wheel turned, the scooped-up water was carried to a higher place.

When the wooden plank reaches its highest point, the water is poured into the bamboo water trough connected to it.

The bamboo water trough was set up at an angle, and the water flowed down the bamboo tubes all the way to a small ditch dug next to a small vegetable garden that Li Xuan had cultivated.

Although the water flow is not large, it is indeed continuously lifted from the low-lying ditch to the high-lying area and then flows into the vegetable garden!

"This...this..."

Di Xin stared wide-eyed, his mouth slightly agape, unable to utter a complete sentence for a long time.

Huang Feihu even squatted down to get a closer look at how the wheel turned and how the water was carried up, his face full of disbelief.

"A divine object! It truly is a divine object!"

Di Xin finally regained his voice, which trembled with excitement, "Without magic or supernatural powers, relying solely on this ingenuity and human effort, it's truly possible to draw water upwards?!"

He seemed to see the hope that countless farmlands could break free from the shackles of the gods' rain!

Li Xuan stopped, wiped non-existent sweat from his forehead, and smiled faintly at Di Xin's excited expression.

"This is what they mean by 'human will can conquer nature'."

He said it so casually.

However, the moment the words "Man can conquer nature" were uttered, it seemed as if the voice of the Great Dao was gently humming in the depths of the void.

An indescribable, powerful, and resilient force, like a sleeping dragon being awakened, quietly surged in the long river of human destiny, seemingly showing a barely perceptible upward trend.

This change is completely imperceptible to ordinary people.

But Di Xin, who was standing in front of Li Xuan, suddenly trembled!

He is the Human Emperor!

Bearing the immense destiny of the entire human race!

He felt it clearly!

That throbbing deep within their bloodline, that river of destiny symbolizing the collective will of humanity, was stirred by Li Xuan's casual remark, creating unprecedented ripples and revealing an unprecedented spirit of vigor and indomitable will!

When Di Xin looked at Li Xuan again, his expression completely changed.

The previous shock, curiosity, probing, and even the apprehension caused by the other party's unfathomable strength have all transformed into utmost solemnity and an indescribable fervor.

This person!

This person is definitely Di Xin's lucky star!

This is the only hope for Da Shang to turn its fate around!

It is the key to whether humanity can truly stand tall!

Li Xuan was completely unaware of the strange phenomena caused by his casual remark.

He had been enthusiastically demonstrating just moments before, but now, seeing Di Xin and Huang Feihu marveling at the waterwheel, he felt deflated and rather bored.

"Sigh, I understand it now, and it's useful," Li Xuan kicked a pebble at his feet, his tone tinged with helplessness and worry. "But this thing is fine for us to use ourselves."

"How can you say that? You can offer it to the King of Shang. His Majesty will definitely reward you handsomely!" Huang Feihu added.

Di Xin nodded in agreement.

"Send it over?" Li Xuan shook his head upon hearing this. "I don't know any kings or ministers."

He looked at Di Xin, his brows furrowed tightly.

"Besides, Father, even if you're an official in the Shang Dynasty and know some people, this matter... is far too risky!"

Li Xuan thought about it more and more and felt that it was unreliable.

"Think about it, if this thing really gets widely adopted, cutting off the incense offerings to those gods who make a living by controlling the clouds and rain, and cutting off the source of income for those charlatans who rely on sacrifices to pray for rain, will they just let it go?"

He pointed at the waterwheel as if it were a hot potato.

"At that time, any monster with some power, or any petty deity who doesn't like us, might just blow a breath or send some wild monster with a hundred years of cultivation over..."

"My son and I, and this Brother Huang, aren't we all doomed? My little shabby yard will probably be burned to the ground too!"

He sighed, his face showing an expression that said, "This deal is too unprofitable."

"So, this is something we should keep to ourselves. Promoting it? Forget it, our lives are more important."

Di Xin and Huang Feihu were still immersed in the awe brought by "human will can conquer nature" and the waterwheel when they heard Li Xuan's "cowardly but justified" words and almost choked.
