Autumn harvest has arrived in the blink of an eye. This year's harvest is more than double that of last year, and there is no problem in making it until next year's autumn harvest. Everyone is very happy and works with extra energy.

It seems that because of the long-lasting natural disasters, even God felt guilty. After the snow disaster, no more disasters occurred. During the autumn harvest, the weather was sunny and bright. There was no need to worry about rain falling halfway through the harvest, causing the wheat and other crops to fall to the ground, sprout, and rot.

There's no need to worry about the harvested grain sprouting or getting moldy because it won't be dried in the sun. However, sweet potatoes and corn make up the majority of the grain grown in Songlin Village, and these two can be stored for a while longer before being dried in the sun.

The corn is dried and then the kernels are removed. Sweet potatoes can be sliced, dried in the sun, and then stored away. When you want to cook them, you can take some out. These dried sweet potatoes are raw. After cooking them, they are dried in the sun and can be eaten as snacks. Children usually carry a few pieces in their pockets and take one to chew when they are hungry, which makes them very happy.

When adults go into the mountains or to work in the fields, they can carry a few pieces in their pockets to fill their stomachs, which is very convenient. The process of making sweet potato chips is very simple, but if Song Zhuiyan doesn't teach them, no one will know how. Last year, Song Zhuiyan taught them how to make them once, and this year they took them back and started making them.

Some people even use potatoes to make dried potatoes. Dried potatoes are certainly not as delicious as dried sweet potatoes, but they are easier to store. Families who grow potatoes will make them into dried potatoes.

Because Song Zhuiyan said that potatoes that have sprouted should not be eaten as they can cause poisoning, but if they are made into dried potatoes, there is no need to worry about them sprouting. The villagers are very clever.

Song Zhuiyan planted an acre of rice, but the harvest was not good. She used seeds of hybrid rice from a thousand years in the future. In modern times, an acre of good land can yield more than 1,600 catties. The land in Songlin Village was reclaimed from wasteland, so the yield was less than half. She didn't know if it was due to geological reasons or insufficient fertilizer. This time, she only harvested 700 catties of rice.

The villagers were all amazed and marveled. "People in our village have grown rice before, and the maximum yield per mu is only about 400 jin. People in the neighboring village have also grown it, but they yielded even less, less than 400 jin. I heard that in the south, the yield is less than 500 jin per mu."

“That’s right. Our wheat and millet harvest is less than 500 jin, but Miss Song can harvest 700 jin. That’s really amazing. It seems we should learn from Miss Song how to farm.”

The villagers from the original Linjia Village gathered around, chattering excitedly.

"The rice variety also plays a big role. This time I planted a superior variety, a hybrid rice developed by the father of rice, which is why it has such a high yield. However, fertilization is also crucial."

Then Song Zhuiyan gave a brief introduction to Grandpa Yuan Longping, focusing on the benefits and advantages of biogas digesters. That's right, the biogas digester hasn't been built yet. Before, they didn't raise many pigs, but now they have more than 320 adult pigs and more than 20 piglets.

The pile of pig manure was very high. Although villagers would occasionally come to carry the pig manure to fertilize the fields, nothing beats a biogas digester. Not only is it environmentally friendly, but the fertilizer fermented in the biogas digester is also more effective and can kill insects and bacteria.

Putting pig manure into a biogas digester will prevent you from smelling pig manure from a long distance, which will make you lose your appetite. Of course, even with a biogas digester, the smell won't be completely gone; you still need to clean and disinfect the pigsty frequently.

In short, there are many benefits, but unfortunately, biogas cannot be used for cooking, at least not for the time being. There is no biogas stove and no biogas pipeline. If we want to make it, we have to invent it, which will drive people crazy.

Song Zhuiyan had specifically looked up some information beforehand and knew that a biogas stove mainly consists of nozzles, valve assembly, air regulating plate, ejector, and burner, etc. The nozzles control the flow rate of biogas...

It's incredibly complicated. If you just buy it, it seems like a simple matter, but when you have to make every single part yourself, it becomes extremely difficult, very difficult indeed.

However, giving up is impossible. Just because there's no way to do it now doesn't mean there won't be a way in the future. One day, we'll be able to cook with biogas.

The first step is to build the biogas digester, and then we can slowly study how to make a biogas stove. Ye Moxun has been very annoyed by research lately, so asking him won't work. We can only look for a target among the other children.

"Is the fertilizer produced from that fermentation pool really that effective and can increase grain production?" the villagers asked hopefully.

"When have I ever lied to you? Absolutely not. Look at the cement floor now. Our shoes won't get dirty when we walk on the road in the rain. It's convenient for drying wheat, rice, or anything else. Isn't it practical?" Song Zhuiyan brainwashed the villagers with a serious expression, repeatedly urging them to make more cement and then build biogas digesters.

This year everyone has enough food, so she won't give them any more grain as payment for their work. However, she will build a biogas digester for them and provide them with a full lunch.

“But we don’t raise pigs, and from what you’re saying, one or two pigs won’t do the job. We need to raise at least ten to make it worthwhile to build a proper pens. This is not a good idea.” Nobody has time to raise so many pigs. They have to work. If they don’t do farm work, they have to go up the mountain to chop firewood and pick wild vegetables and fruits.

Pigs eat a lot. If you raise so many, does the whole family have to go out and cut pig feed every day? Even if you can raise so many pigs, who will you sell them to when they grow up? Your family can't eat that much meat. Okay, even if you can eat that much pork, who would be willing to eat it like that? You work yourself to death and can't make any money. What's the difference between that and working for nothing?

Besides, what if there's a swine fever outbreak and the pigs die? Wouldn't that be heartbreaking?

Everyone's analysis is correct. After thinking for a long time, Song Zhuiyan said, "That makes sense. Why don't you help me build it, and then we can share the fertilizer equally? Of course, we can only share it equally for the first three years. After three years, we can't share it like that anymore. I want two shares, and you can have the remaining one."

After thinking it over and discussing it, the group sent a representative out and said, "We can help you build a biogas digester, and the fertilizer will be distributed as you said. However, we need two kilograms of grain as payment for the labor. You don't have to provide meals."

"Two jin of sweet potatoes or potatoes, but I can't give you the rice; I'm keeping it for myself," Song Zhuiyan said.

After some haggling, Song Zhuiyan agreed to pay for the labor with one pound of sweet potato and one pound of potato. However, since the cement was made by everyone through hard work, even though the Song family provided the formula, the villagers were the ones who contributed the labor, so they also had to pay for the cement.

That's incredibly precise, truly amazing.

Ye Moxun then stepped forward and spoke up, "I teach the village children to read and write, and I treat the villagers and prescribe medicine, but I haven't taken any money or grain from you."

"Fine, I'm easy to talk to. I made you write IOUs for the doctor's visits and medicine, and I'm returning them to you now. You don't need to ask Aunt Song for your wages for making cement."

Song Zhuiyan was the only one who was truly conscientious in distributing food to everyone. In fact, these days, the least valuable thing is people. If they weren't trapped in the mountains, they could find laborers everywhere as long as they had food to eat. Everyone knew this perfectly well. It's just that they were used to getting paid, so they were more calculating.

After Ye Moxun's suggestion, no one said anything more, and the matter was settled.
