I will lead the whole village to occupy the land and become the king.

Jiang Qinyu was stunned. Unlocking the entire first floor of the supermarket at once? There was such a good thing? She had to take it!

After being surprised for only a second, Jiang Qinyu immediately chose "yes".

[Ding! Mission: Please collect and unlock the first level of mission items according to the map prompts. There is no time limit for this mission. The specific mission items required include...]

Jiang Qinyu soon understood that completing the task of unlocking the first floor of the supermarket in one go was actually to reduce the burden on the host.

In previous missions, each required mission items weighing over a hundred kilograms, but this time, only one of each type is needed, but with more varieties.

But Jiang Qinyu's supermarket is a super large comprehensive one, which has almost all kinds of things. For example, agricultural machinery generators that are rarely seen in other supermarkets can all be bought in her store.

In addition to the regular supermarket on the first floor, there are also some jewelry brands, and there are even car companies holding auto shows in the lobby, but all of them are now in an unlocked state.

Jiang Qinyu was a little curious at the moment. If she unlocked all five floors of the supermarket, would she be able to use everything inside?

After all, some of them belong to merchants and brands, like the common medicine counters, clothing on the third and fourth floors, etc., which logically do not belong to her.

Just as she was thinking, Jiang Qinyu heard Meng Tianze calling her.

"Sister-in-law, have you finished shopping so early?"

Jiang Qinyu turned around and saw Meng Tianze also coming over with a bunch of things. She smiled and replied, "I just bought some bath beans and other things for the family. I saw someone selling meat, so I bought some to take back for the children."

Now that she has unlocked the fresh meat area, there will be no shortage of meat at home for the time being, but she still has to pretend to have enough for outsiders.

Meng Tianze saw that she was carrying a lot of things in her hands, and thought of the rumors in the village before, and sighed in his heart.

This girl, is she worried about her brother's two children? But she really needs to eat some more, look at how thin she has become!

"Then why don't you buy some more? Don't you have enough money? I have some here, how about I buy some more for you?" Meng Tianze was about to take out the money.

Jiang Qinyu quickly waved her hands, "No need, Brother Meng, fresh meat won't last in this weather, these are enough."

In fact, she had bought all the meat from the butcher just now. If Meng Tianze went there again, she was afraid that she would be exposed. After all, she didn't have so much meat on her hands.

"That's true. Okay then, let's come to the town again after you finish eating." Meng Tianze nodded.

Jiang Qinyu smiled and nodded.

Chen Shao and Liu Yazi arrived soon after, playing and joking. They put their things away and headed towards the village.

"Come to think of it, it's been so dry this time that we don't have any fertilizer left at home. Fertilizing after we plant the seeds will be a problem."

Chen Shao drove the carriage back, and Meng Tianze and Liu Yazi sat on the shaft. After walking for a while, Meng Tianze sighed.

Jiang Qinyu lifted the car curtain and looked at the plants on both sides of the road. She felt unhappy, but she still knew a little about how to make compost.

"It's okay if we don't have enough fertilizer at home. We can go to the mountains and get some dead leaves or something to ferment. It will have the same effect after fermentation."

She heard this method from several old farmers when she went to the countryside for internship after graduation.

She thought it was novel at the time, so she listened carefully, and the memory of it is still very clear.

"Fermenting?" Meng Tianze was stunned. "How do you ferment?"

Jiang Qinyu looked at him in confusion, "Don't we make compost in our village?"

When I was in the Lu family, I didn't really care about the farm affairs. It was Old Man Lu and Mrs. Chen who were busy with these. Jiang Qinyu really couldn't remember how the villagers fertilized the land besides using farmyard manure.

"What are we using to ferment? Isn't it just the stuff stored in our own toilet that we use on the land?" Meng Tianze said in confusion.

Jiang Qinyu: "..."

Well, she is a lazy person who doesn't know how to grow crops, but one day she comes to teach farmers who deal with the land all year round how to make fertilizer. How can this be justified?

Jiang Qinyu really didn't expect that the agriculture in this world was so backward. Apart from farm manure, it was completely dependent on the weather.

There is a reason why Dai Viet’s grain production is low. It seems that there is still a long way to go to improve this situation.

When Grandpa Jiang and the others heard that the fertilizer used in the fields could be artificially made, they were shocked.

"Girl, is what you said really feasible? Don't make fun of your grandfather!" Grandpa Jiang looked at Jiang Qinyu uncertainly.

Now everyone in the village knows that Lu Yanzheng is dead, so Jiang Qinyu has naturally become a widow. However, she is still a girl, so it is reasonable for the older generation to call her a "girl".

Jiang Qinyu nodded and said, "Grandpa Jiang, I've seen all this in my eldest brother's book before."

"Is this really in the book? Then why didn't anyone tell us?" Grandpa Jiang was very skeptical.

Scholars don’t need to farm, so why write these things in books?

Jiang Qinyu didn't expect them to not even know this, so she had to explain briefly, "Actually, the Ministry of Industry and the Ministry of Households both cover farming techniques, but maybe the policies vary from place to place, so maybe there's no one here to teach us?"

"Mrs. Lu is right," Liu Ruyi suddenly emerged from the crowd, looking at everyone with a smile. "Emperor Shengzu attached great importance to agriculture back then. He even had the Ministry of Works and the Ministry of Revenue jointly compile a booklet specifically to teach people how to farm."

She only knew that this incident happened, but she didn't know what was written in the booklet. Moreover, after so many years, the booklet might have been changed by someone.

But she was also very curious, how did Jiang Qinyu know so much?

Everyone in the village knew that Liu Ruyi was from Beijing. After hearing what she said, they immediately believed Jiang Qinyu's words and asked her to teach them how to make compost.

"It's not that difficult, actually. Didn't we see a bamboo forest in Tiger Valley before? It's somewhere like that. We can find some, dig up the layer of soil covered with rotten leaves, cover it with straw or something, and let it ferment..."

Jiang Qinyu told the people of Dingshui Village exactly what she had heard.

The farmers were very focused on farming. This time, no one interrupted Jiang Qinyu, and those who didn't understand scratched their heads. After Jiang Qinyu finished speaking, they asked questions one by one.

Jiang Qinyu also explained the fermentation process, the results of fermentation, and the impact of the fermented fertilizer on the crops in the field.

"We still need to let the kids read more!" This was Grandpa Jiang's first sigh after hearing this.

Someone echoed, "Yeah, look at A Zheng's wife, she knows everything. It's a pity that the school in our town is closed, alas!"

"How about this," Village Chief Li looked at Jiang Qinyu thoughtfully, "When we have nothing to do in the winter, let's ask our eldest niece to give us lessons and teach us how to read?"

As soon as this proposal came out, everyone looked at each other in surprise, and then Grandpa Jiang was the first to express his opinion, "I think it's a good idea! Yu girl is very capable, and I'm sure she can be taught well."

"Uh, well, why don't we just let the kids learn? I'm already this old, what else do I need to learn?"

"That's right, just let the kids learn it, we don't have to..."

People who get a headache when they hear the word "reading" immediately back off.
