Starting with ten elixirs of immortality, I led the First Emperor to rebel against the Qin Dynasty.

A barbecue left everyone with heavy hearts.

Ying Zheng, Li Si, Meng Tian, ​​and Bai Qi were all awestruck by the immense value of the method for refining salt.

Fusu, on the other hand, felt lost about his life over the past twenty years. The classic texts he had studied since childhood were of no use to his country, and his affinity for Confucianism always angered his father.

And this "younger brother" in front of us can benefit the country and its people with anything he takes out.

Only Zhao Huan ate to his heart's content, completely unaware of what was happening.

After the meal, Zhao Huan cleaned up the mess, while Ying Zheng subtly steered the conversation to the matter he cared about most.

"Huan'er," Ying-Zhao Zheng-Zheng said casually, picking up a cup of water, "that potato you mentioned before is indeed a divine product. Before I came back this time, I had some people try planting some, and they've already sprouted. However…"

He sighed, a perfectly measured look of worry on his face.

"This stuff is good, but it's too laborious to grow. It requires deep tilling, but we don't have many oxen, so we have to rely on manpower to dig with hoes, which is too slow. It's probably difficult to spread it on a large scale."

This is indeed the most troublesome problem for Ying Zheng at the moment.

Zheng Guo has already reported that the potato trial was very successful, but the biggest obstacle to its widespread adoption is cultivation efficiency.

With the Qin Dynasty waging war year after year, oxen were already a valuable strategic resource, with most of them in the army and even scarcer among the civilian population.

Without sufficient animal power, relying solely on human labor to turn the land is incredibly inefficient.

When Li Si and Meng Tian heard Ying Zheng mention this matter, they both put down what they were doing and pricked up their ears.

They also wanted to know if the all-powerful Prince Huan had any good solutions to this problem.

Fusu also looked at Zhao Huan, wanting to see how this "younger brother" would deal with such a practical issue concerning the national economy and people's livelihood.

"Oh? Is that all?"

After listening, Zhao Huan wiped his hands and said with a relaxed expression, "Father, I thought it was something serious. It's just that the tilling is slow, simple."

Simple?

Ying Zheng, Li Si, and Meng Tian exchanged glances, each seeing expectation in the other's eyes.

Fusu's heart skipped a beat. Could it be... there's a way to do this?

Zhao Huan turned and walked into the storage shed in the corner of the yard. A moment later, he came out dragging a strangely shaped farm tool.

The thing was also made of wood, but it was unlike any plow he had ever seen before.

The Qin government promoted a heavy and cumbersome straight-shaft plow, which required two people to hold and two oxen to pull it from the front, making it extremely inconvenient to turn.

The plow in front of us has a curved shaft, a more ingenious design for the plowshare and plowshare, and a small, sharp plowshare. There are also several additional parts on the side for turning and breaking up the soil.

The plow itself looked more than twice as light and agile as the straight-shaft plow promoted by the Qin government.

"Father, look at this." Zhao Huan patted the farm tool and proudly introduced it, "This is called a curved plow. I figured it out myself when I had nothing else to do. It's much better than those big, straight ones we use now."

"Quyuanli?"

Ying Zheng, Li Si, Fu Su, and the others all gathered around, curiously examining this unfamiliar object.

"Will this thing... work?" Meng Tian asked with some doubt. He looked at the plow and saw that it was more than half the weight of the ones used in the army. He felt that it was not very sturdy and that it might fall apart if he exerted too much force.

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

Zhao Huan shouldered the curved plow and said to everyone with a smile, "Come on, there's a newly cleared wasteland behind the village. I'll show you how it works."

The group followed Zhao Huan to the edge of the fields behind the village.

This is a newly reclaimed piece of land, and the soil is still very hard.

"Brother Huan, Grandpa Bai, are we going to plow the field?"

A chubby-faced little boy ran over; it was Shi Tou, who had been training with Bai Qi these past few days.

"Yes, Stone, tell your father to borrow your donkey for a while." Zhao Huan smiled and patted Stone's head.

"Okay!" Stone replied crisply, then turned and ran home.

A moment later, Shi Tou's father led over a sturdy donkey with a glossy gray coat. He was somewhat reserved when he saw Ying Zheng and the others, who were of extraordinary bearing, but he was very enthusiastic towards Zhao Huan.

"Young Master Huan, you can just say so if you need a donkey. Why make the child run the whole way?"

"Haha, Uncle Gang, you're too kind." Zhao Huan took the reins and skillfully harnessed the curved plow to the donkey.

This scene left Li Si and Fusu, who were standing behind Ying Zheng, stunned.

Using a donkey?

Aren't oxen used for plowing? Can a donkey pull such a big thing?

Zhao Huan held the plow with one hand and the reins with the other, and softly shouted, "Giddy up!"

The donkey then started walking forward at a leisurely pace.

To everyone's astonishment, the seemingly nimble curved plow easily broke through the solid ground. As the donkey moved forward, the soil was neatly turned up and rolled to one side, forming a beautiful wave of earth.

Most importantly, Zhao Huan was the only one involved throughout the entire process.

He can easily control the depth and direction of the plow with one hand, and when turning, he can skillfully turn the plow around by simply lifting the tip of the plow.

A donkey and a person.

This was something they couldn't have imagined before.

Ying Zheng, Li Si, Meng Tian, ​​and Bai Qi stared intently at the ever-extending furrow in the field.

Fusu stared blankly at the rolling soil, as if he could see countless potatoes being planted, the granaries of the Great Qin filled with mountains, and countless people being spared from hunger.

His belief that "all other pursuits are inferior, only studying is superior" was once again severely challenged. The change in a farming tool could bring about such a dramatic transformation.

Is this something that Confucianism could truly achieve?

"This...this...this is the curved plow?"

Li Si swallowed hard, trying to get his brain working again.

As the Prime Minister of Qin, he knew all too well what this meant.

The oxen used for plowing in the Qin Dynasty were strategic resources, and their numbers were extremely limited.

Donkeys and mules, however, are far more numerous.

If this type of plow can be widely adopted, it means that the efficiency of farming in the Qin Dynasty will increase several times over.

And then there's the terrifying yield per acre of potatoes...

An unprecedented golden age of Qin seemed to be slowly unfolding before his eyes!

"Your Majesty..." Meng Tian looked at Ying Zheng excitedly, "This is a national treasure! It's no less valuable than a million-strong army!"

Ying Zheng remained silent, staring intently at Zhao Huan in the field, his deep eyes burning with an unprecedented light.

A national treasure? No!

In Ying Zheng's view, this curved plow was more important than a million-strong army.

An army is used to expand territory and conquer enemies.

This thing is used to stabilize the world and feed the people.

With it, the foundation of the Qin Dynasty can truly be as stable as Mount Tai.

Standing to the side, Fusu looked at the undisguised excitement on his father's, Li Si's, and Meng Tian's faces, and then at his "younger brother" who was relaxed and carefree in the field. He felt a mix of emotions.

For the first time, I realized so clearly what I, my father, and the core of this empire were thinking. They were thinking about how to make the country stronger and how to prevent the people from going hungry.

And what about himself? He was pleading for the sorcerer, struggling with the rules of etiquette and ancestral laws, and worried that excessive killing would offend the natural order.

At this moment, Zhao Huan had easily finished plowing a small patch of land, and carrying the curved plow, he walked towards Ying Zheng and the others.
