Carrying the Bamboo Horse on the Thousand Miles Return from the Doomsday Natural Disaster

Xu Lingfeng suddenly thanked him for taking precautions. He and Gu Yu had been focusing on developing lamps for indoor cultivation that did not require photosynthesis. They were all made not long ago and have already entered the experimental stage. They deliberately turned the original aviation building into an indoor planting area. After vacating all the rooms and rearranging them, they have been improved into a planting area that uses new light tubes to regulate temperature, humidity and perform photosynthesis. Zhang Xun and his team worked overtime day and night, but now they can all be controlled by computers.

They specially copied all the planting techniques they learned from Walter's base here. Moreover, improvements have been made, and now it can be considered as a gap in the food supply. In this way, there is no need to plant these plants in the land to obtain food. The impact of natural disasters has been minimized.

It was Xu Lingfeng's foresight that saved the food reserves at the Togetherness Base. Otherwise, even if you get bumper harvests in the first few times, you will be unable to continue. It’s impossible to survive on the first four harvests, right?

Moreover, the acid rain has been falling for a week, and it has not stopped halfway. All underground water sources have begun to be polluted. Fortunately, there are many water purification devices in the Guyu space, which were originally used to purify sea water. After trying it, she found that it also played a certain role in purifying acidic rainwater. As long as the water enters the water purifier and then the filtered water is boiled, it is completely non-corrosive. Of course, Guyu didn't just take out all the seawater purifiers carelessly. Zhang Xun, Xie Wen, Zhao Da and Xu Lingfeng took out the filter element of the water purifier together. Xu Lingfeng convened people to follow Zhang Xun's command and turned these things into large-scale water purification equipment. Otherwise, what would happen to the plant planting area?

The northwest base's drinking water has not been particularly affected. According to the telegrams they sent, their lives were also affected to a certain extent at the beginning. Grain production should also be reduced a lot. But what they are prepared for is that they have already been studying soilless cultivation and methods that do not require planting outside.

So the current situation at the northwest base is pretty good. The vegetable base is not good, they don’t have many scientific researchers. Even without any scientific research, they have been relying on plants grown in greenhouses. Therefore, most of their food production still relies on land cultivation.

This time, their greenhouses were severely corroded, and acid rain eroded groundwater and land. All the seedlings they planted have been burned to death. There are also big problems with water sources. Xu Lingfeng was afraid that there would be problems with the vegetable base, so he had already transported all the cannons to the outside of the wall of the Togetherness Base and formed a circle. All the cannons have iron roofs, which means that the Weather Together base is now an iron ring. Ordinary armed forces cannot attack.

This kind of weapons and equipment cannot even keep up with the northwest base. Naturally, the vegetable base will not be unhappy about this for the time being. The acid rain lasted for more than a week. When it stopped, Xu Lingfeng took everyone to a meeting. It is obviously impossible to protect the base solely by relying on the cannons under the iron shed. The cannon will not fire automatically, and everyone must be on duty 24 hours a day. The consumption of human resources is also very high.

Fortunately, when Xu Lingfeng was studying the map, he knew that there was an iron mine more than 2000 kilometers away from the Wind and Rain Base. It has all been abandoned, but there are still a lot of iron ore resources. He drove his car and Zhangxun used a drone to explore this point.

Xu Lingfeng wanted to transport iron ore back from there, and then make all the outer walls into steel. Directly use red-hot molten iron to water the siege city, so that acid rain can't corrode it, and sandstorms can't do anything either. And the cannonballs won't penetrate even these hits. Xu Lingfeng's proposal was unanimously approved by everyone.

Now the problem comes. If the men have to go out to transport iron ore, they must leave some people at home for defense. Basically all the men have to be transferred out, so all the food crops in the base will have to be produced by women. Although there is computer control, manpower is not unnecessary.

Xu Lingfeng divided the people into three teams. He led a team of regular troops up the mountain to find iron ore, and drove all the trucks to transport it back. The second team, Xu Shunyi, led the militia reserves up the mountain to cut wood because iron ore was to be calcined. This thing definitely requires a lot of wood and charcoal.

Qu Hai's remaining group of regular soldiers stayed at home. In addition to protecting the base, they also had to build stoves. Because of the fear of acid rain coming again, all stoves have to be built in places where they can be temporarily sheltered.

The acid rain only gave Xu Lingfeng a week to prepare, and then it started raining again. This time the acid rain did not last for a week like the last time. This time it was raining lightly, and the patter was continuous. The rain is as thin as silk, but once it falls on a person's body, the skin will immediately become red, swollen and blistered. This kind of rain makes people difficult to guard against. It is very distressing because this kind of light rain is accompanied by the wind and blows on people. As long as it falls a little, especially on thin skin areas such as the face and neck, it will make things worse. If not treated in time, the skin will become red, swollen, ulcerated and inflamed.

Xie Wen took Zhao Da's father and several other doctors to study many prescriptions. Reluctantly, I developed an ointment that could temporarily relieve the pain. Gu Yu secretly gave Xie Wen a large bottle of space water, so that adding a little bit at a time to the ointment developed in this way would be more effective. At least it is much more effective in relieving the burning sensation than their simple ointment.

Xie Wen is trustworthy, so Gu Yu will give him space and water. She has been very careful not to show any flaws with others. When Xu Lingfeng came back, he brought back good news. While they found the iron mine, they also found the coal mine. So part of the iron ore they shipped back was coal.

It took Xu Lingfeng a week to transport everything back before the acid rain came again, and he started calcining it on the same day. Guyu found a video of glass firing from the space. There is sand everywhere in the northwest, and there is no shortage of raw materials. Guyu has tried it, and glass can withstand the corrosion of acid rain, and it seems to be better than iron. She considered making a protective shield out of glass so she wouldn't have to carry an iron sheet around the world. It’s heavy and difficult to move around, but glass is light, and I can think of ways to make it thinner. Someone has an idea, can glass be made into silk, woven into cloth, and made into a raincoat? Gu Yu thought this was a good idea and began to lead people to develop this new type of protective clothing.
