Chapter 351

"And...your candied haws."

Three streets away, the little fat man handed the last candied haws back to Qin He with an incredible look on his face.

The man just gave him a string of candied haws and left with the beaten Feiyuwei officer.

I thought he didn't want the candied haws anymore, but I never expected that he would come to me from three blocks away.

This is so fucking~

"You only left one for me? Where's the sugar on it?" Qin He took the candied haws, his face twitching. At this moment, there was only the last one left on the candied haws handed to him, and the sugar wrapped on it had been licked clean.

"How would I know you would come back to ask for it?" The fat man looked Qin He up and down with contempt, but what he said was the truth.

What he didn't know was that the reason Qin He was able to find him across three streets was because he had used a marking technique on him.

If he had known, he would not be looking at him with contempt, but pointing at him with ridicule.

The dignified Green Ox Immortal uses the marking technique to find candied haws.

How petty is this!

If I had known this earlier, I would have finished it quickly. Why bother licking the candy for so long?

"At least keep half of it." Qin He looked disgusted. The fruit, which he didn't know what it was, was slippery and covered with saliva.

"Tsk, I don't even want your candied sweet potato haws." The fat man rolled his eyes in disdain and walked away with an arrogant look on his face.

In troubled times, skinny people are everywhere, but there are few fat people. Since he is fat, he is definitely not from an ordinary family, so a string of candied haws is not a rare thing for him.

However, Qin He did not lose his temper at this moment, but was stunned instead.

Because the fat man said that this candied haws was a "sweet potato" candied haws.

This made Qin He's mind flash with lightning.

Sweet potato, also known as sweet potato and sweet potato.

This is a high-yield grain that is not picky about the land and can be grown on any piece of land in the wilderness.

With this thing, all land can become fertile farmland.

In addition to sweet potatoes, there are also corn and potatoes, which are known as the three high-yield treasures.

Before Dali, the vast Eastern Land could accommodate a maximum population of 80 million. Any more would inevitably lead to chaos.

Only after a riot kills most people and the contradiction between people and land is eased can we start over.

This is the secret of the cycle of order and chaos.

But in that later time and space, even though there were years of war and people were living in poverty at the end of the Di Dynasty, it still maintained a population of 40 million.

A five-fold difference!

This is the contribution of high-yield grains.

There is no need for any advancement in farming technology, just a difference in crop varieties.

The wheat and rice in this time and space are not only low-yielding, but also delicate. A slight drought or flood will result in a total loss of all harvest.

"Is this really a sweet potato?" Qin He looked at the last candied haws in his hand.

How can I describe the taste? After chewing the thin layer of sugar coating on the outside, it tastes like chewing wax. It is not bitter, sweet or astringent. I can't taste anything. It also has a strong fibrous feel and is not at all like the sweet potato of later generations.

"Could it be because the variety has not been improved?" Qin He was suspicious, not knowing whether this was a sweet potato or not.

After thinking about it, Qin He went to the vegetable market.

If you want to know where this thing can be bought, the most likely place is the vegetable market.

After a while, we arrived at the vegetable market.

Grandma Huang is still carefully picking vegetables in the corner of the vegetable market. She moves very slowly, and her wrinkled face reveals the kindness and tranquility of time.

On the cattails in front of me, bean sprouts, cabbage, and leeks are neatly arranged, looking bright and juicy.

When Granny Huang saw Qin He, a smile spread across her kind face: "It's been a long time since I saw you, young master, come to the market."

"Just got back from a long trip." Qin He smiled and squatted down, saying, "I heard your son was ill a while ago. I wonder if he's feeling better now."

"It's all right, it's all right." Grandma Huang's face lit up even more, and she said, "It's all thanks to the Green Ox Immortal. Not only am I healthy again, I even passed the provincial examination last autumn."

When talking about her son, Grandma Huang couldn't help but say a few more words.

"Oh, this is a successful candidate, congratulations."

Qin He smiled and bowed, then added, "The Spring Examination will be here soon. If your son makes another advance, he'll be a Jinshi in the third list, maybe even the top scholar."

"Thank you for your kind words, sir." Grandma Huang smiled so hard that her eyes narrowed.

Afterwards, Qin He chatted with Grandma Huang for a while, then took out the sweet potato and asked, "Grandma Huang, where can I buy this?"

"Is this a sweet potato?" Grandma Huang looked at it with her cloudy eyes and said, "They have that kind of thing over at the pig farm. I think it's used to feed pigs. I've never seen it before."

"Pig farm?" Qin He's eyes lit up slightly.

Damn, it turns out this thing was originally used to feed pigs.

The man selling candied haws actually used pig food to make them. He has a very bad conscience.

Bah, profiteer!

After getting the news, Qin He went to the pig farm again.

Qin He knew about the pig farm, and coincidentally, it was also an asset of the Prince of Zhongshan's Palace.

In times of chaos, food prices have skyrocketed, making it difficult to get food, let alone meat.

Only the wealthy and powerful would set up livestock farms in order to obtain a stable supply of meat, and consume some moldy and damp grain, basically producing and selling it themselves.

Not long after, Qin He left the city and came to the pig farm, where he found a mountain of sweet potatoes in a shack.

They were all harvested from the fields. The sweet potatoes were about the size of a child's fist, and were covered in mud with their dead shoots.

A man who looked like a manager was lying on a rocking chair, and three or five servants were busy chopping and packing food into barrels to make pig feed.

Seeing this, Qin He changed his magical robe into a red robe with flying fish pattern, put the embroidered spring sword on his shoulder, and walked towards there with a swagger.

The person in charge was called Qiu Sanhai, a Class D steward of the Prince of Zhongshan's Palace, and the least favored one at that level. He was thrown into this pig farm and had to spend all day surrounded by animals and pig manure.

When Qiu Sanhai saw Qin He, he shuddered.

The red robe and flying fish uniform are the color of the robe of the captain of the Feiyu Guard. At the very least, he must be a great detective.

Each of these people is a ruthless character who will wipe out an entire family if they disagree with someone.

Qiu Sanhai and several servants did not dare to neglect and hurried forward to greet him: "My humble servant Zhu Dachang greets Feiyu Shangba."

Although this is the property of the Prince of Zhongshan's Palace, he, Qiu Sanhai, is just a marginal steward of the palace. He has neither the confidence nor the courage to neglect a captain of the Feiyu Guard.

What surprised him was that this captain appeared alone.

"Did you grow these sweet potatoes?" Qin He asked straight to the point.

"Yes, yes, I led them to plant it." Qiu Sanhai nodded vigorously, and then cautiously asked, "I wonder if your Excellency can help me with anything?"

"Tell me the truth, when did you start planting sweet potatoes, what were you planting them for, and where did you get the seeds from?" Qin He threw all the questions at him.

Although sweet potatoes are high-yielding, it took a long time for them to be discovered and accepted by people.

I never expected that this place has grown to such a large scale. It is really surprising.

When Qiu Sanhai heard Qin He's questions like he was interrogating a case, he was so scared that he almost peed his pants. In panic, he confessed everything he could and couldn't say.

It’s still the same word, profit.

The pigs fed in the pig farm are counted, and the amount of damp and moldy grain sent in is also counted. Although there are a hundred or eighty pigs, pigs are precious livestock after all. Regardless of size, life or death, they must be handed in for inspection and slaughter.

There wasn't much room inside for Qiu Sanhai to enrich himself, at least not enough to satisfy his appetite. Otherwise, it would never have been Qiu Sanhai's turn to manage this pig farm.

Without any background or support, Qiu Sanhai couldn't be bold enough.

Since there is no way to make a profit from pigs, the only option is to make a profit from pig feed.

This is in line with the saying that everyone in the world is seeking profit, and everyone in the world is seeking profit.

After much inquiry, Qiu Sanhai finally found a pig feed that could replace moldy and damp grains, which was sweet potato.

He asked someone to get some seeds from the south, and began to test planting and feeding on a small scale. After finding that there was no problem, he became bolder and planted all the wasteland around the pig farm.

Sweet potatoes are not picky about the soil, require little care, and don't need fertilizer. They will produce as soon as they are planted, it's just a matter of how much.

Now that the pigs have new food, the moldy and damp food that has been transported can be freed up and sold.

By making profits from this, Qiu Sanhai has finally lived a more comfortable life in recent years. He has a lot more money, raises pigs well, and his servants are rated high every year.

Qin He's sudden appearance made him instinctively think that his affairs had been discovered by the Zhongshan Palace, and that they were using Feiyuwei to arrest him.

"Shangguan, please spare me, Shangguan, please spare me, I will never dare to do it again." Qiu Sanhai knelt on the ground, feeling terrified.

"Why should I spare your life? I was just passing by to take a look. This thing is very good. Plant more." Qin He said, and then patted Qiu Sanhai and others on the head one by one, turned around and left.

Everyone looked at each other, covering their heads in shock.

Because they all have a lot of strange knowledge in their minds, called "Sweet Potato Breeding and Planting Technology".

This is... a miracle!!
