Natural disaster at the beginning: I rely on the space to lie down with delicate salted fish

Speaking of which, as a researcher who focuses on human psychology, directly exploring the basic physical and chemical properties of an unknown substance makes Xie Shu not know where to start. Thinking back to the chemical physics he learned in middle and high school, talking about a substance Most of them are physical and chemical properties, such as color, smell, and state at room temperature. There are also some that need to be measured to know, such as density, hardness, electrical conductivity, thermal conductivity, specific heat capacity, etc., and even reactions with acids, alkalis, and salts. .

The properties of a substance are so complex that even if you really explore them one by one, you may not be able to cover everything. However, if we start from the perspective of human needs, it will be a lot more convenient. After all, it is something for your own use, not a research sample placed in the laboratory. There is no need to have the idea of ​​​​finding out everything. Moreover, in reality, even if there is a manual, the function description of the item cannot be said to be comprehensive. It is like a football, can it only be used for kicking? Although the rules are like this, these rules are limitations of people on things rather than shortcomings of the things themselves. Footballs can be picked up and hit people, and the hollow inside can be used to hold water... It's just that people don't usually use them like this, but it cannot be denied. Have such functionality.

That being the case, Xie Shu also just wanted to see if this bamboo had some of the characteristics and functions he wanted. As for whether it had other properties, maybe he would occasionally develop them in the future, maybe he would discover something accidentally, or maybe he would just forget it for the rest of his life. But it doesn’t matter, even without this bamboo to relieve comfort, it is already a state of contentment. An extra portion can be regarded as the icing on the cake, and a less portion will not affect survival.

I probably thought about how I felt when I just came into contact with the bamboo. Although green bamboo is not as hard as purple bamboo, which can completely withstand being cut by a hatchet, it is obviously lighter in comparison. Xie Shu had just dragged five or six bamboos to the yard, and it didn't take much effort to ponder them carefully.

Xie Shu split a section with a hatchet and held it in his hand. He carefully looked at the hole at the port. The bamboo wall was not as thick as Xie Shu expected. It didn't feel heavy in his hand. He could even throw it up a few times. Compared with normal bamboo, it can even be said to be "thin and thin". It was split into several pieces, and Xie Shu tried to pick up one of them and break it off, but found that the bamboo was not as brittle as he thought, but rather very tough. Even if it was full of moisture and had not been air-dried, it could still be bent. It folds to a great extent and has good resilience.

If it weren't for being cut by a knife, Xie Shu felt that he could use the bamboo to weave it into a soft whip. When he was a child, he had seen the bamboo whip held by the teacher in class, but Xie Shu had never experienced it personally. However, although the bamboo whip could be described as "weak and boneless", it was more frightening to the students than a thick wooden stick picked up casually. He still gave it to Jie Shu was deeply impressed. Looking at this bamboo that can be bent almost at will but can return to its original shape with its toughness and elasticity like a shape memory alloy, it is wrong to say that Xie Shu has no idea of ​​using this characteristic to make some handicrafts or weapons. possible.

But the most important thing is to see how the bamboo reacts with acid, alkali and salts. The key point is whether it can prevent acid rain, and whether other situations will occur in extreme cold and extreme heat. Rather than weapons, Xie Shu is more concerned about whether these bamboos can be used as building materials.

There is also a lack of building materials among the supplies Xie Shu collected, especially those that are cold-resistant, high-temperature resistant and acid rain-resistant. However, compared to those building materials and equipment that he is not very good at using and installing, it is obviously more convenient and faster to simply make a bamboo raft that can be disassembled at any time. .

As for how to study, it would be more convenient. While ensuring the safety of the surrounding environment, find some containers that can be used as experimental equipment. For acid rain, use solutions such as hydrochloric acid and nitric acid to test acid rain, as well as various alkalis, including Soak the salt-rich sea water directly in it to see if the bamboo can withstand it.

It's not an experimental study. As long as it's safe, it doesn't matter if it's precise or precise. There are also extreme cold and extreme heat. Throw it into the fire and see how long you can endure. If you can withstand the fire, then you can naturally withstand even the extreme heat. There is also extreme cold. Ordinary dry ice should not be hot enough, so Xie Shu directly added liquid nitrogen.

As time went by, and each practice proved it, Xie Shu went from being hopeful at the beginning to now with a smile on her face as if she had found a treasure. No, it was not as if she had found a treasure, she had indeed obtained a "treasure". Although bamboo is not unaffected by all kinds of abuse, to this extent, Jie Shu can almost think that it is a material with excellent acid and alkali resistance, high temperature resistance and extreme cold resistance. No matter what kind of "torture" it has experienced, although the surface of the bamboo joints taken out is somewhat affected, it can be ignored. For example, a layer of ice is attached to the surface of the bamboo joints taken out from the liquid nitrogen, and it becomes obviously dry after being taken out by fire. , no change can be seen in the sea water, but in acid and alkali solutions of different concentrations, the bamboo joints only have slight changes on their surface. Except for the green color becoming lighter, the acid and alkali have not harmed them at all.

In this way, Xie Shu can also roughly characterize this green bamboo. Although the hardness is not high, it is thin, light, tough and elastic, and it is acid and alkali resistant and can withstand high temperatures and extreme cold.

Such an excellent material is perfect for building a house. Xie Shu doesn’t plan to build another place. He previously stocked up containers and wanted to use them as “outdoor mobile tents.” Since the bamboo is so good, he can then cover the containers with a layer and take this opportunity to give the containers a better surface. Make some decorations.

However, today's experiment has already taken a lot of time. Even if the flow rate in the space is different from that of the outside world, it has not been long, but the fatigue that the Jieshu entity can feel is quite a lot. After cleaning up the entire test site, Xie Shu went to take a shower to make sure it was clean, and then went to the side room to find some cooked food and returned to the real world to enjoy.

In the following days, Xie Shu focused on the bamboo utilization project and renovated the container, especially the appearance. In addition to covering it with bamboo, it was also covered with a layer of firewood picked up outside the suburban warehouse. As for preparing weapons, Xie Shu still planned to read and study first.

……

This morning, Xie Shu had finished exercising and was reading a book on the massage chair when he heard a strange sound coming from downstairs. It didn't sound like it was coming from the 25th floor. It seemed that it was from a lower floor. Sensing something was wrong, Jie Shu sat up straight and looked down. He felt relieved after seeing one of them clearly. Thinking that he should come out and see the other person, Jie Shu put the bookmark on the page in front of him, got up and got off the massage chair, put on his going out clothes and walked out.
