However, the blueprints are in hand, and the weather is getting warmer. The key is that this thing uses minimal materials and the manufacturing process is very simple. Simple to manufacture means cheap, and cheap might actually attract buyers.

With that thought in mind, Jiang He took the design drawings and went back.

After returning, a special group was formed to make manual fans.

Soon, a small, manual fan was finished. Perhaps because the weather was still too cold, they actually thought it produced a strong breeze.

After the products were made, we held another meeting to discuss the plans. After the Lunar New Year, one team will continue producing heating systems, as winters in Northeast China are long and it will be quite a while before it warms up again. There will still be buyers. Additionally, we need to produce a batch for this winter to avoid running out of stock later.

Others were already busy preparing fans for the summer.

Their main product now is ceiling fans, which sold like hotcakes last year, and sales this year will definitely be good too.

However, the question arose whether or not to make the hand-cranked mini fan.

In the end, everyone agreed that if no one wanted them, they could just start over, but they didn't dare to make too many. They only made five hundred to test the waters.

As for Lin Ying, she knew that the Second Factory's actions were a gesture of goodwill; their intention was clear: they didn't need the blueprints anymore. Therefore, her small fan was a way of expressing her gratitude. Naturally, she wouldn't accept payment for the blueprints.

Moreover, Lin Ying is more concerned about something else than the Second Factory.

Last year, after delivering grain to the farm, Lin Ying had been thinking about one thing: how to repay the farm.

She couldn't offer any high-tech food varieties because she couldn't explain their origin or how they came about. So, instead of offering something she wasn't good at, she decided to offer something she was good at.

Farming involves only a few things; she's not good at seeds, and she's not skilled in machinery either—things that can directly change things significantly. Therefore, she focused her efforts on assisting with farming.

For crops to grow well, not only do the seeds themselves need to be good and the soil need to be fertile, but resistance to diseases and pests is also very important.

During her postpartum confinement period, the book she read most often was about poison.

Because her grandfather didn't teach her this, it became the topic she was most interested in.

In fact, many pesticides contain toxins from poisonous plants. Aren't those a type of poison?

Moreover, when the military region was farming, she made something similar, but the cost was too high, and it was simply not feasible for the farm to cultivate on a large scale.

Therefore, Lin Ying is now considering something that is low-cost yet useful.

Lin Ying was at a dead end because, no matter what, pesticides made from Chinese medicinal herbs were not as convenient and quick as chemical pesticides. Although pesticides made from Chinese medicinal herbs wouldn't pollute the environment or harm crops, in this day and age, people don't care about being all-natural or healthy; they only care about effectiveness and high yield.

The pesticides Lin Ying makes may not only be less effective than chemical pesticides, but many may only repel insects rather than kill them.

In that case, she's not helping, she's making things worse.

Lin Ying then remembered that the military seemed to have switched to chemical pesticides instead of the pesticide formula she had provided.

Lin Ying understood. After all, the pests are different every year, and she hadn't provided a better formula. People always need more effective solutions. So changing pesticides was perfectly reasonable.

Therefore, if Lin Ying wanted to provide pesticides, they not only needed to be more effective than others, but also more convenient, faster, and cheaper. This left her with no options. Even within the spatial system, there was nothing like it for sale! In short, there was absolutely no way to offer her any advice.

Just when Lin Ying was about to give up, she suddenly saw mothballs.

Camphor balls keep ants away precisely because of their scent.

If she could create something that has the same effect as mothballs and emits a volatile odor, wouldn't that solve the pest problem?

However, regardless of the circumstances, this substance was poison. Lin Ying wanted to help the farm, but only if it meant she couldn't harm the child. The child was currently breastfeeding, and frequent exposure to poison would definitely affect the baby. Therefore, in the initial stages, Lin Ying focused primarily on her studies.

She knew there was no chance to produce a finished product this year. But this gave her ample time to learn about this subject.

Besides that, she also has time to tidy up the house. For example, she can put up a fence around the yard.

Six months after Liu Zi was born, Lin Ying left the child with her other children and went back to work. She used a handcart to haul stones to build the courtyard wall, piecing it together bit by bit.

With a courtyard wall and a gate installed, we finally have a decent home.

After that, she paved the path from the house to the front door with stones. In her spare time, she also repaired her little car. She relied on it a lot for getting around, so she couldn't let it break down.

Lin Ying really wanted to buy a car from her spatial storage, but the current circumstances simply didn't allow it.

However, although circumstances didn't allow her to change the vehicle, she could replace some of its core components. For example, she replaced the steam engine with an electric motor. She also replaced the diesel heater with an electric one.

The car's frame was changed from wooden planks to a steel frame.

It wouldn't be an exaggeration to say that Lin Ying's current vehicle is practically an electric car. Not only that, but she's also replaced the wheels with wooden ones covered in rubber. Car wheels are too conspicuous, and she thinks bicycle wheels can't support her weight. But people will probably think she's wasteful.
