Chapter 139: Impregnable
"Solar water heaters are not easy to make either."
"If it is a true solar water heater, of course it is impossible. Whether it is a glass vacuum tube, a metal collector, or a ceramic heat-absorbing coating, we can't do it. Come out, not to mention the need for a circulation pump and a series of temperature sensing and automatic control devices, but we don’t need that complexity now.
“Because the water volume is small? "Chen Mu tried to ask.
"Yes, even if it is just wrapped in water with iron sheets and left to dry in the sun, it is enough for us. Tang
Jing sighed: "So, heating is actually not difficult. Our biggest problem is heat preservation."
"Is it possible to make something similar to a thermos? " "
As you all know, the most critical part of the thermos flask is the vacuum liner in the middle. For us now, there is simply no way to do this."
"But if it can't be kept warm, heating doesn't mean much. "
"Is it okay to use an off-the-shelf solar installation? " "
Theoretically, it's possible, but it doesn't seem to be available in school. Even if it is, it's almost impossible to operate it."
"So, we talked for a long time, but it was still in vain. " "
"of course not. Tang Jing smiled and said, "The reason why I am telling you this question is actually to talk about another matter." "
"What's up? "
Solar energy actually takes up a lot of space. If we install such a big thing outdoors, we will probably be noticed in a few days, so..." "You don't want to..." Chen
Mu Already somewhat understanding, he raised his head subconsciously.
"Yes, solar energy, of course it must be installed on the roof. "After Tang Jing finished speaking, she stretched out her hand and pointed to the top of her head.
"Ah? "Wei Dalei raised his head stupidly.
The storage room is 2.8 meters high. To them, it is like a skyscraper. Anyway, they can only see a ceiling, and the specific details cannot be seen clearly.
However, what we are talking about now is Putting a solar panel on your roof?
“That’s a bit of an exaggeration. "Dong Junwei couldn't help but murmured.
"Of course it's not possible now, but it's definitely not far away. "Tang Jing said with a smile.
Many times, what Chen Mu envied was not Tang Jing's knowledge and mind, but her confidence in being able to control the future.
Tang Jing continued: "But what I want to say is that for the entire room The utilization of height is something we need to consider in the next step.
"Is it too early? " "Dong Junwei frowned.
"It's not too early to tell. We can make use of the wall first.
"Wall? "
"Well, it's just like the observation tower on the door, except that the wall is thicker and more difficult. " Chen
Mu nodded in agreement: "I tried it last time. The white ash on the wall was loose and falling off. There was no way to modify it. After all, this house hasn't been built for a long time. Why is the quality so poor?"
Tang Jing said with a smile: "Strictly speaking, these small houses are illegal constructions and are temporary. It's just because they are built in the school and no one will take care of them. So when they were built, they definitely didn't care about them. " It is also a relatively inferior material. "
It won't collapse. " "He Ying was worried.
"It's not that it's difficult for a small house like this to collapse. It's just that in order to save money, we don't use good latex paint for things like wall paint. It seems like we just use lime. Two layers of water were applied, and the proportion of lime to water was not adjusted properly.
" Also add alum and salt. " "Chen Mu nodded.
"Can you still paint the wall? "Tang Jing tilted her head and asked with a smile.
"I have helped people before.
"Early on, some people added rice soup, but your method is older, and the truly processed slaked lime itself can be used directly as paint. There is no need to add salt or anything. But now, everyone either uses latex paint. " Or just add glue to the white ash to save trouble. This house should be the latter, but it was obviously not done well, and the ash started to fall off soon after.
"Is there any solution? " "
"No. Tang Jing spread her hands and said, "We can only shovel off the surface of the wall." ”
“This workload is huge. "
"It's not like you need to shovel the entire wall clean, just shovel whichever side you want. "
"All right. Chen Mu nodded: "But what exactly are we going to do?" "
"On the one hand, we need to build a lookout on the remaining three walls to prevent people from coming around from behind without us knowing. On the other hand, I think we still need to do some defenses. "
"for example?
"Such as dropping bombs from an observation tower. " "
"is it necessary? "
You have also seen the strength of Yizhong and Qingbei. Even if we can't confront them head-on, we must at least have some means of self-protection. Although we haven't been exposed yet, as time goes by, it is difficult to guarantee that we will not be exposed." Discover. "
"Um. Chen Mu nodded in agreement: "Last time we injured so many of them and robbed Gu Yinglong, No. 1 Middle School must be looking for us." "
Tang Jing said: "My idea is to build this place to be impregnable first, so that we can advance, attack, retreat and defend, and reserve food for at least one year. "
One year?"
"The rice we have now can last for almost a year. Of course, we still need to go out to look for other things from time to time. But with these 12 boxes of rice, we are more confident. What's more, as long as potatoes are stored properly, they can also be eaten. " Leave it for a month or two. "
"Have food in your hands, don't panic in your heart. "
That's what it means. " Tang Jing said with a smile: "In one year's time, even if we don't have any new members, I believe everyone's abilities will reach a new level. At that time, we can do more things and don't have to be too afraid of others." People. "
"But. Chen Mu frowned: "The superpowers in Qingbei and No. 1 Middle School will continue to grow, and with combat as training, they may grow faster than us."
Tang Jing said: "Battle can indeed train people, but casualties will inevitably occur. Although they have many people, they are only one or two hundred in the end. How much loss can they withstand? " "
To be honest, I have always felt that the understanding of supernatural powers over Qingbei is far better than ours. After all, they have more people and have more reference standards. Before, Song Yu inexplicably killed some small insects on the road. When he arrived, Now we can't figure out why. "
Chen Mu is generally a proactive person, but perhaps because of his experience, he often thinks the worst about things. Tang Jing said:
"At present, the diversity and complexity of superpowers are far beyond In our imagination, I don’t think there is much difference between the two hundred people and the twenty or so of us.
"In addition, both Qingbei and No. 1 Middle School have a huge disadvantage."
"What?" Chen Mu was curious.
"They don't have me." Tang Jing showed a strange smile.
There is still a chapter to be written, but it may be midnight. Let’s read it tomorrow morning. It’s a pity that the manuscript has not been saved.
