Su Hua raised her eyes, took in the man's expression, and smiled. "Actually, finding this sweet potato was a complete accident. I rescued Da Bai in the back mountain a few days ago, and its parents came looking for me and brought a lot of gifts as thanks."

Among them was a wild buffalo, from which a small sweet potato fell. I found it intriguing and planted it in a ceramic pot.

Unexpectedly, when searching for Hongxiao for Zichen, they encountered a herd of wild buffalo again and followed them to Sweet Potato Valley.

During my trip to Fuhu Mountain, I discovered that the sweet potatoes had grown considerably, so I dug some up. The basket of sweet potatoes I carried today is from about one-third of an acre, weighing approximately 430 jin (about 215 kg).

Beside the wooden house, Yu Feng and Qing Dai listened to the girl's clear and cold voice, and then looked at the sweet potato that had fallen on the ground. Their eyes widened in surprise.

Twenty or thirty sweet potatoes were grown in one ceramic pot.

If over 400 jin of sweet potatoes could be dug up from a small plot of land, wouldn't a single mu (unit of land area) yield 1300-1400 jin?!

Moreover, these are still unripe sweet potatoes. If they were fully ripe, wouldn't the yield be even higher?

Although they did not farm themselves, they understood agriculture and sericulture. Even in years with favorable weather, a mu of fertile land could yield a maximum of two shi of grain, or 240 jin.

How many times larger must this sweet potato be than rice and wheat?

Even the usually composed Xiao Jinhan was unsettled upon hearing this. "Hua'er, could you take me to see this sweet potato valley?"

“Of course, but there’s no rush.” Su Hua nodded. Just then, the time for acupuncture arrived, and she raised her hand to remove the silver needles.

Almost immediately after the needle was removed, the man vomited a mouthful of black blood.

Su Hua took out a handkerchief from her sleeve and handed it to her. "The triple poison in your right leg has been cured. Stay home obediently for the next two days, and your right leg will gradually recover and you will be able to walk normally again. Once your leg is healed, I will take you to see the Sweet Potato Valley."

In the valley, there were about three or four acres of land. At first, only the innermost acre had sweet potatoes. Later, she planted many more sweet potato vines. After watering them with spatial water droplets once, they grew very vigorously.

"Okay." The man wiped the blood from the corner of his mouth, his eyes smiling. "I'll do whatever Hua'er says."

Su Hua thought for a moment and then added, "These sweet potatoes have very low requirements for growing conditions. They can grow well even in barren mountain areas. As long as the climate is suitable, it may not be impossible to plant two crops a year."

"Two seasons a year?" Xiao Jinhan murmured. "If that's the case, wouldn't the total yield of one mu of land be more than double that of 1,300 or 1,400 jin a year?"

Upon hearing this, the two people behind the wooden house both gasped in shock.

If such a high-yield crop were to be introduced, wouldn't it cause a sensation throughout the entire Yu Dynasty? No, not only Yu the Great, but even the Southern Frontier, the Western Rong, and the Northern Ming would all be eyeing it.

Especially in Beiming, which is mountainous and covered in snow and ice, food is extremely scarce. In recent years, during the famine months, people have been raiding the villages north of Dayu to steal food.

Xiao Jinhan's gaze shifted several times before he recalled the girl's earlier words, "Hua'er just said she wanted to discuss this sweet potato with me. I wonder what she wanted to discuss?"

Su Hua pursed her lips. "If I were to use these sweet potatoes to secure a guarantee for the Su family, Zichen, do you think it's feasible?"

Actually, she never intended to use sweet potatoes as a bargaining chip from the beginning. She only wanted to wait until the sweet potatoes were ripe before launching them. But the Su family wanted to move forward, and they would only encounter more and more problems in the future.

She wanted the Su family to have more confidence on their own, instead of waiting for Xiao Jinhan to help them with everything.

After all, an unbalanced relationship, if left unchecked for too long, will only be a mirage, unable to last.

The man was taken aback by the rare hesitation on her face, then chuckled softly, “It is only right to exchange something of great benefit to the country and its people for a guarantee. His Majesty is not a stingy person.”

Among the 1,480 counties under the rule of Yu the Great, villages like Shanghe Village were not uncommon. Villagers toiled in the fields all year round, yet they could hardly afford to eat their fill.

They eat two meals a day, mixed with wild vegetables from all seasons, just to barely make it until the next rice harvest season.

If you encounter natural disasters or man-made calamities, even just getting by is a luxury.

Sweet potatoes can be harvested twice a year, with a total yield nearly ten times that of rice and wheat. Once introduced, millions of people in Dayu will no longer have to worry about not having enough to eat.

In the military camp, hundreds of thousands of soldiers no longer need to worry about military rations. At that time, why should Yu the Great fear the disturbances of neighboring countries?

Such a beneficial item for the country and its people deserves to be replaced with a different guarantee; it is entirely reasonable!

Thinking of this, the man felt a pang of sadness. If others had discovered the sweet potatoes, they would probably have been thinking of ways to benefit themselves, but she still put her family first.

But he didn't want her to suffer a loss.

He needs to go to the capital city in person.

The man's mind raced, and he beckoned to Yu Feng, "Go find Yu Yu now. His mountain run is over. Let him stay in the sweet potato valley for a while."

In addition, send some people to Zaozhuang to keep an eye on things. Until everything is settled, the sweet potato matter must be kept secret.

"Yes, I will take care of it immediately," Yu Feng replied, bowing respectfully.

With the sweet potato matter temporarily resolved, Su Hua began to work on sweet potato flour at home.

Before she time-traveled, she had only watched bloggers make sweet potato noodles in videos, but she had never made them herself. Fortunately, she had a good memory and remembered most of the basic steps.

After washing the sweet potatoes, the first step is to grind them into sweet potato starch.

The Su family used to have a stone mill for grinding rice and flour, which was perfect for grinding sweet potatoes. The sweet potatoes were sliced, placed in the middle of the stone mill, and the mill handle was held to grind the sweet potato slices into a paste.

Since it was her first time making it, Su Hua only chopped ten catties of sweet potatoes. She was strong, and with her two sons, Su Dalang and Su Erlang, helping her, the ten catties of sweet potatoes were quickly ground into small pieces.

Then, put the ground sweet potato puree into a pre-sewn gauze bag and wash it repeatedly in clean water until all the starch in the sweet potato puree is washed out.

After washing away the starch, it needs to settle overnight.

The remaining sweet potato residue in the gauze bag should not be wasted. It should be mixed with chicken feed and fed to the chickens, who then happily ate it.

Once the amount of sweet potato starch produced increases, the daily sweet potato residue can be sent to Zaozhuang to feed pigs.

Not long after taking over Zaozhuang, Su Baishi couldn't stay idle. She spent a lot of money raising twenty piglets in Zaozhuang, at two hundred coins each. These days, all the leftovers from the Su family restaurant were sent back to Zaozhuang to feed the piglets.

Nowadays, Su Bai makes a trip to Zaozhuang every day. Seeing that the piglets are growing well, she has started looking to raise some goats.

It was as if they were taking back all the bad luck they had previously suffered.
