Because of the existence of a five-person decision-making team, the rest of the team often does not think much about the overall problem, but has more time to ponder their own abilities.

Chang Junyan is a typical example.

This guy's brain hole is getting bigger and bigger now.

Under Tang Jing's research and guidance, the role of his abilities is also constantly being developed.

"Listening to Tang Jing, your control has been strengthened a lot?"

Tang Jing would talk to Chen Du about the abilities of everyone in the organization after a while, but as the number of people increased, Chen Du gradually couldn't take care of everyone.

Chang Junyan laughed, "Yes, now I want it to itch, if he doesn't itch, he won't itch, and he can control the degree of itching, and when it's the most itchy, I can't stand it myself." ”

"But what's the use of that?" Chen Du was somewhat speechless.

"It works." Chang Junyan said excitedly, "For example, when I sleep, I can grow two bags in my ears to block the sound, so that I can't hear Lao Wei's snoring at all, you can't do it, haha." ”

Although Wei Dalei was already in a separate room, because the distance was not very far, if he woke up at night, he could still hear his snoring.

Of course, it's much better than before.

"By the way, why scratch the bag when you can stop itchy?"

Chen Du looked at Chang Junyan, who was standing in place and constantly rubbing his feet, and really felt powerless to complain.

"Because it's cool." Chang Junyan looked right.

Chen Du "......"

In Chen Dui's opinion, Chang Junyan's ability is very desirable in terms of defense, since this is the case, of course, he should continue to dig into the depth of his ability in this direction, and still scratch and play like before, it seems to be a bit of putting the cart before the horse.

But Chang Junyan obviously didn't think so, and Tang Jing seemed to support him in doing so.

It was Tang Jing's main responsibility to guide the development of other people's abilities, and Chen Duan, as the most experienced and mentally powerful and controllable person, was naturally qualified to guide others.

It's just that when the two disagree, Chen Du usually takes the initiative to back down.

"Then come on." Chen Du made a cheering gesture.

"Uh-huh."

Chang Junyan kicked his shoes and slowly paced towards the toilet.

Chen Du looked at his back, a little worried that this guy's shoes would be damaged in advance, but looking at his appearance, it is estimated that it is better to have no shoes, and the soles of his feet are directly rubbed against the cement floor, Chen Du feels good for him when he thinks about it.

……

After breakfast.

Chen Dui, Dong Junwei, Tang Jing, Wei Dalei, He Ying, and the five gathered next to the water tank.

Since the completion of this set of water diversion devices, the efficiency of use is actually not high, because there is no bathroom, everyone can only use the temporary partition near the door for the time being, and can not shower.

And after other more important things were almost done, Chen Dui also shifted his attention to this.

It's time to build a bathroom.

In fact, at my current size, water is used in a completely different way than it used to be.

Taking the cup used for drinking water as an example, it is actually difficult to make the action of "pouring water", and the so-called drinking water is more like sucking.

Because of the surface tension, atmospheric pressure, and capillary phenomenon of water, the shape of water is very different from the previous one at today's scale, and naturally formed water droplets have a minimum value, which is also very large for today's humans.

Especially when the pipe is small enough to rely on gravity, the water cannot be continuous, but becomes drop by drop.

This creates a big technical problem for the shower.

If the amount of water is too small for the water flow to be continuous, then you can only take a bath and keep pounding the water droplets on the top of your head, and then wipe your whole body, but then there is no point in showering.

But if the amount of water is too large, people are likely to be unable to stand and even be washed away, and with the current conditions of enlightenment, the use of water has not yet reached the point of being extravagant.

After several calculations.

Eventually, it was decided to abandon the shower scheme.

Use a bathtub instead.

The bathtub is almost extinct in ordinary families nowadays, on the one hand, it is troublesome and time-consuming, and on the other hand, it is a waste of water.

And it's a bit of a luxury to have a bathtub in an apartment with such a high price as today, and end up only for fish and basins.

But now in this case, the bathtub is a good choice.

Compared with showering, bathing at this time is more water-efficient, about two or three droplets of water can fill a bathtub that can be used for humans to lie down.

The five of them had agreed and decided on a location not far from the water tank.

"At the moment, we don't have a lot of people, and we can have a bathtub per person, but in the future, we still have to consider a more optimized shower solution."

"How about a public bath?"

"If there are more than 100 people, it's not impossible, but drainage is still a problem. At present, the scale of this bathtub is that if you pour water on the ground, it will evaporate and dry in a while, but when it comes to the bath, I am afraid that a drainage system will have to be installed. ”

"I have a question." He Ying said suddenly.

"What?"

"In the current weather, there is nothing wrong with taking a bath, but what about winter weather? There's no hot water. ”

"It's up to the squad leader." Tang Jing said with a smile.

"Boil water?" Dong Junwei said.

Tang Jing nodded, "My initial idea is to build a metal coil, which will be heated by the squad leader before everyone takes a bath, and the temperature of the water can be controlled as long as the temperature, pipe length, and water outlet speed are calculated." ”

"Water heater." Wei Dalei exclaimed.

"But is it true that every time you take a bath in the future, you have to heat it up with the squad leader?"

Although the method is a good way, it always sounds unreliable and cannot be implemented for a long time.

"For the time being, there is only so much that can be done by relying on us and the materials in front of us."

"Is there a way in the future?"

"In fact, technically speaking, the difficulty of central heating is not high."

"Build a big stove?"

"It is also a direction to consider, but the fuel is more troublesome, the initial coal, the later natural gas, the principle is not complicated, the difficulty is only that the amount of engineering is too large, and a certain level of remote control and automation is required, otherwise people simply can't get close to the furnace, talk about the operation."

"It doesn't seem to be possible anytime soon?"

"Hmm." Tang Jing nodded, "The use of open flames, before there is no certain number of people, is really cost-effective, and it will be accompanied by higher safety risks." ”

"Fire?"

"Yes, with our current size, even the smallest flame is difficult to extinguish, and the flame doesn't matter how big you are, once it catches up, we won't even have time to escape."

Several people fell silent, imagining what the odds of them would be able to escape if the storage room caught fire while they were sleeping.

"And what do you mean by central heating?"

"Actually, we have a relatively easy source of heat." Tang Jing said this, stretched out his hand and pointed out the window.

"Solar!?"
