Dressed as a big boss Bai Yueguang, God does not allow salted fish to lie down

At present, the only grain that can be grown is corn, and the only vegetables that can be grown are a few kinds of high temperature resistant ones, such as tomatoes, spinach, winter melon, loofah and the like.

This is even with the sunshade in place.

The people of Zhongli generally have enough food, because work has not stopped here due to the end of the world. Everyone avoids the four hottest hours of the day and uses the morning and evening to work.

Gradually, people began to figure out how to survive better in the end times.

Those who can actively embrace change will eventually survive, and once external conditions improve, these people will live more brilliantly in prosperous times.

If you keep sitting at home complaining about your fate and don't actively look for ways to survive, death will be the norm in the apocalypse.

The people of Zhongli sent out more than ten thousand rescue workers, medical personnel, and house builders.

Su Yuejian planned to bring these people back in another month.

Currently, various places are undergoing vigorous reconstruction, which requires a lot of large modular bricks and stones. Su Yuejian opened a brick workshop and began to transport goods to surrounding areas in need.

Mosquito coils also began to be sold everywhere in the extreme heat.

The economy is recovering little by little.

Su Yuejian also began to work on economic recovery.

First, we need to train agricultural officials at all levels and promote regenerated rice.

Second, we must promote the production of the three high-yield grains, potatoes, sweet potatoes, and corn, on a large scale across the country.

Third, we should launch a nationwide campaign to build brick and stone houses to replace the previous thatched houses.

Fourth, we must vigorously promote upland cotton and vigorously develop the cotton textile industry.

The fifth is to improve transportation efficiency by building official roads in each prefecture and streets in each county.

After Su Yuejian finished writing a plan of several thousand words, she used the power of space displacement to place it on Nangong Li's desk.

Aunt Amber also began to recruit more people in Zhongli, plant cotton, and expand the cotton mill.

Su Yuejian summoned Gu Bingxiu, and the extra manpower could be used to start building roads. They should first repair the roads connecting Zhongli with the counties and prefectures around it.

Su Yuejian began to make her wishes come true in the spiritual space, and she came up with the idea of ​​a bicycle and a tire carriage.

Then study the structure, disassemble the parts in detail, and draw them.

After leaving the space, Su Yuejian took the drawings to the carriage shop and learned the specific sizes of the current carriage wheels.

Su Yuejian planned to make the rubber obtained from the space into solid tires, upgrade the carriage, and make a standardized carriage tire.

It all started with the rubber experiment. After looking up information at the Cross Star Library, Su Yuejian had a general direction in mind.

The specific steps are to chop the air-dried rubber into small particles, add quartz sand powder, carbon black, etc., and then mix them thoroughly in a large manual mixer.

After repeated cycles, the two are fully crushed into the smallest particles, then heated and poured into an iron tire mold, heated and flattened.

The design of the mold determines the final shape and size of the tire.

In the mold, the rubber is pressed into the shape of a carriage tire.

During the entire experimental process, Su Yuejian needed to repeatedly experiment with the proportion of materials, the heating temperature, the grinding of the tire molds, the standardized customization of the sizes, and the final vulcanization.

The process of curing rubber by applying heat and pressure is called vulcanization.

It can transform rubber from a plastic state to an elastic state.

The temperature and duration of the vulcanization process depend on the size of the tire, the manufacturing process and the compound used.

Therefore, this process requires repeated experiments, and a dedicated person is required to mark each time.

Xiao Yaoer said that she would help her elder sister and manage the business in the future.

Su Yuejian wanted to give the carriage tire business to her.

"Yao'er, you have to work hard. If you make this business bigger, you can become rich and a lady of a wealthy family."

"Really? Are you really willing to leave it to me?"

This matter is simple. The general direction and raw materials are available, but there are no industrial machines. Everything depends on manual labor, and the process is inherently inefficient.

What we need to experiment now is the feed ratio, heating temperature and duration.

Su Yuejian handed the specific experimental work over to the craftsmen, and they needed to report to Xiao Yaoer every seven days.

There are also auxiliary tools, mixers, and crushers, which need to be improved and optimized on the original basis.

Xiao Yaoer reports the progress every seven days, and Su Yuejian is in charge of the progress of rubber manufacturing.

Soon, rubber manufacturing became a thing, and Xiao Yaoer specifically went to find a craftsman who made carriages. She said that all carriage wheels in the future would use rubber tires.

Axles that were previously made of wooden structures will now be made of iron.

The outer layer of the iron axles is coated with a layer of black paint.

This is what is going on on both sides at the same time.
