I will make Qin Shi Huang immortal in the Great Qin Dynasty.

Thirty shi?

His brain started working at lightning speed in that instant.

Even in the best years of good weather, the best fields in the Qin Dynasty could only yield about three shi (a unit of dry measure) of millet per mu (a unit of land area).

Thirty shi is ten times. Ten times!

"Grand Preceptor, how much did you say?" Ying Zheng wondered if he had misheard.

"Thirty shi," Qin Tian repeated, "and I'm talking about an easy breakthrough. If the land is good and managed properly, forty or even fifty shi isn't impossible."

silence.

A long silence.

Ying Zheng's mouth opened slightly, then closed, then opened again, then closed again.

His eyes were wide open, reflecting the vast land beneath his feet, but his gaze was no longer there.

The yield is 30 shi per mu.

Ten times the yield of millet.

If all the fields in the Qin Dynasty were planted with potatoes and sweet potatoes, the Qin Dynasty's grain production would increase tenfold.

What does ten times mean? It means that the Qin Dynasty can support ten times the population, ten times the army, launch ten times the wars, and expand its territory ten times, even a hundred times!

ten times!

Ying Zheng felt his heart pounding in his chest, so fast and hard that it felt like it was about to burst out of his chest.

He felt his blood burning in his veins, making him feel hot all over. He felt so hot that he wanted to take off his heavy imperial robes and rush into the sea in front of him, letting the cold water extinguish the raging flames in his chest.

"Corn yields are slightly lower than potatoes and sweet potatoes," Qin Tian continued, "but they are still seven or eight times that of millet. Moreover, corn tastes much better than millet; it's sweet and sticky, and it's delicious boiled, roasted, or ground into flour to make pancakes."

"Potatoes and sweet potatoes go without saying. Potatoes can be a staple food or a vegetable. They taste good no matter how they are cooked: steamed, boiled, roasted, stir-fried, deep-fried, or stewed. Sweet potatoes are sweet and can be eaten raw, steamed, boiled, or roasted. They can also be sliced, dried, and used as dry food, ground into powder to make noodles, brewed into wine, or fed to pigs."

Ying Zheng's breathing became increasingly rapid.

His chest heaved violently, making a panting sound.

Meng Yi noticed His Majesty's unusual behavior and was startled. He was about to step forward to ask when he saw Qin Tian wave his hand slightly, indicating that he didn't need to worry.

It's not a physical problem, it's just that I got too excited.

"Grand Preceptor," Ying Zheng finally found his voice, which trembled uncontrollably, "these things you've mentioned... potatoes, corn, sweet potatoes, can they be grown on the land of Qin?"

"Yes," Qin Tian said decisively. "The land in Daqin is perfectly suitable for planting. Potatoes and sweet potatoes have the lowest soil requirements; they can be grown in sandy soil, yellow soil, black soil, and even mountainous and sloping land. Corn has slightly higher requirements, but most of the land in Daqin is also suitable."

It can be grown.

Both can be grown.

Ying Zheng closed his eyes, took a deep breath, and slowly exhaled.

He tried to calm himself down, but he couldn't calm down no matter what he did.

A crop that yields 30 shi of grain per mu, has no requirements for the land, and tastes good no matter how it's cooked—how can there be such a perfect crop in this world?

"Are there any drawbacks?" Ying Zheng opened his eyes and stared sharply at Qin Tian.

He was the emperor; he understood the laws of this world all too well.

Everything has two sides; there are advantages and disadvantages, gains and losses.

A production of thirty shi (a unit of dry measure) cannot be achieved without any cost.

Qin Tian hesitated for a moment, seemingly considering his words.

"Yes," he finally admitted, "eating too much will make you fart."

Ying Zheng was stunned.

Meng Yi was stunned.

The eight soldiers were also stunned.

fart?

Is it really that simple?

"And quite a lot," Qin Tian added, his expression somewhat subtle. "Especially sweet potatoes, eating too many of them is... well, it's quite loud, and the smell is quite strong too."

Ying Zheng looked at Qin Tian's expression that seemed to say, "I'm telling the truth, I'm not lying to you, don't look at me like that," and finally burst out laughing.

"Ha ha ha ha--"

Meng Yi was taken aback for a moment when he saw His Majesty laughing so hard he was doubled over, and then he also started laughing.

The eight soldiers couldn't resist either, grinning and showing their white teeth, their laughter rising and falling.

Eating too much will make you fart.

Is this the only drawback of a superior seed that yields thirty shi per mu?

Ying Zheng laughed for a long time, until tears were almost streaming down his face, before he slowly stopped.

He wiped the tears from the corners of his eyes with his sleeve and waved his hand.

"Being able to eat your fill is the greatest benefit. What's farting? I wish the people of Qin would fart every day, at every meal, from morning till night! Farting means there's something in your stomach, it means you're not hungry, it means you're full!"

Meng Yi nodded emphatically from the side.

Sometimes the soldiers on the border couldn't get enough food, and they only ate one meal a day. They stood guard and patrolled on an empty stomach, trained for battle on an empty stomach, and tossed and turned in their cold barracks, unable to sleep on an empty stomach.

If these grains, yielding thirty shi per mu, could truly be promoted throughout the Qin Dynasty, the soldiers on the border would never go hungry again.

"Alright, enough nonsense, let's find these things." Ying Zheng's voice carried an unprecedented urgency. "Grand Preceptor, lead the way."

Qin Tian chuckled, his body sinking as he plunged down into a valley below.

Wild corn in North America is distributed in the central and southern parts of the continent.

Qin Tian led the group to land in a valley near a river, where large areas of wild corn grew.

Those corn plants were shorter than those cultivated in later generations, and the corn cobs were smaller, but the golden corn kernels were plump and round, clearly indicating that they were of good quality.

Qin Tian walked directly to a corn stalk, broke off an ear of corn, peeled off the green husks, and revealed the golden kernels inside.

He handed the corn cob to Ying Zheng, who took it and examined it for a long time before smelling it. A sweet fragrance filled his nostrils, making him swallow hard.

"This is delicious." Qin Tian said, breaking off a few corn kernels and throwing them into his mouth, chewing them with a crunchy sound, his face full of enjoyment.

Ying Zheng followed his example and also broke off a few corn kernels and put them in his mouth.

After chewing a couple of times, their eyes lit up.

It was sweet, crisp, and had an indescribable fragrance. It tasted much better than millet, and better than any other grain he had ever eaten.

"Alright," Ying Zheng uttered only one word.

Next up are potatoes.

It took Qin Tian some time to find wild potatoes in a forest edge area.

The potato plants were short and unremarkable.

Qin Tian squatted down and dug away the soil around the plant's roots with his hands. Several fist-sized potatoes emerged from the soil, their yellowish-brown skins covered in dirt, looking rather rustic.
