This room is not very high, you can step on anything to get the roof, the roof here is the most resistant to the pressure of the arch, but because it is under a lot of pressure, so it is also the most easily damaged. It seems that it is not difficult to make a hole in the roof, but in fact, the materials and structures used in this kind of civil air defense fortifications are not the same thing as civil buildings at all, and you can see the thickness of the iron door that the walls of this place are definitely not ordinary brick and concrete structures, otherwise it is completely meaningless to install such a strong door.

But Xiaohua said this, it should be certain, I didn't say anything more, packed up my things and went to the end of the aisle.

Xiaohua chose this place to start work, and the big barrel of kerosene happened to be used as a workbench, and Xiaohua stood on it, swinging a hammer and smashing it happily.

This location is a good choice, must have taken into account the problem of extending to the lake as much as possible, I sat against the wall, I was really tired enough, and I wanted to fall asleep, looking at the small flowers outside the door sweating like rain, and I admired it very much. Little Adam was not tired, squatting at the door to watch the excitement, I was afraid of falling something and smashing it, so I beckoned him back and hugged him.

For Xiaohua's idea, I can't help but say that it makes sense, but in the end I still feel very inappropriate, but I can't figure out what is wrong. Rong Yusi sat next to me and chatted with me with or without a match.

This little girl doesn't look very old, but she is actually very knowledgeable, knows a lot of things, and she is also smart, and it is very pleasant to chat, even in the fields that some women should not be good at, there is no sense of playing the piano to the cow in one sentence and eight sentences to explain. After chatting for a while, Rong Yusi suddenly asked a question.

"Si'an, why do you say these Gejia are so afraid of water?"

I have really seriously considered this problem, there are many animals in this world who are afraid of water, but it is really very rare to be afraid of water like Gega, such as sulfuric acid, in comparison, their photophobia is not so serious, it can only be regarded as a habit. I've been fond of science since I was a child, and this strange thing naturally arouses my curiosity, and I've also carefully studied some of the Gega's organizations, and although they are only preliminary conjectures and have not been confirmed, they are more than enough to chat with.

"I've really studied this, I'll tell you about it!"

"Hey, hey, good!" Rong Yusi saw that I was interested, and he was also happy, and he posed as a child to listen to the story, and looked at me with big eyes.

I was taken aback by her posture, and hurriedly looked away to avoid the edge, explaining: "The skin of these Gejia is very strange, it is not a dense layer of connective tissue like the skin of ordinary animals, but many layers of moist mucous membranes, I once opened it and looked at it, just like the skin of a frog......" I looked at Rong Yusi's expression, and continued: "But this mucosal tissue is very tough, and it can secrete mucus by itself to keep it moist, I think it's probably this reason why Gega is afraid of the sun, because the sun dries the mucous membranes on the surface of their skin, but I don't know what the consequences will be when they dry out. ”

"Judging from their performance, it seems that they will just be uncomfortable, don't they chase them out in broad daylight?" Rong Yusi analyzed very seriously, his eyebrows furrowed beautifully, and he seemed to have completely forgotten the original question.

"But their eyes are really afraid of the bright light, and I don't know why." I answered.

Rong Yu thought for a while and said: "The tolerance to strong light mainly depends on whether the ability of pupil adjustment is enough, and these Gejia can't stand the light should be the reason for the narrow range of pupil accommodation." I nodded, but Rong Yusi continued to ask, "You haven't said it yet?" Why are they so afraid of water? ”

I asked her, "Have you ever tasted these gega?" ”

Rong Yusi's expression was very strange, at first it seemed to be frightened and unbelievable, and then it turned into a disgusting expression, "Of course not!" Are you? ”

I saw that she had misunderstood, and hurriedly explained: "Of course I haven't eaten it, but how many times I have killed in and out, it is inevitable that something will splash in my mouth, you should understand......"

Rong Yusi should understand, but he still looked at me with that kind of eyes, I couldn't help it, although it wasn't intentional but it was still a very disgusting thing, so I had to ignore it, and then explained: "That smell is very strong, how can I say it?" It's like condensed soy sauce...... Rong Yusi was about to spit it out, waving his hand and saying, "You don't need to describe it in such detail, you can just say something!" ”

In other words, their body fluids are very ...... "Sticky," I thought about the word, afraid she wouldn't understand, "and their skin is ......mucous membranes," I didn't know what to say, so I gave an example, "You know that if we open our eyes in fresh water, our eyes will be very painful and swollen, but not in seawater, because there is osmotic pressure between our body fluids and fresh water, and the concentration of body fluids in Gega is much higher than ours......"

"Their mechanism of selective passage of cell membranes is not as perfect as ours?" Rong Yu thought for a moment.

I didn't expect this kind of conversation to be so easy and pleasant, "That's it, I've noticed that they bleed quickly in the water, lose their ability to move, and die very quickly." It should be that the cell membrane cannot withstand the internal and external osmotic pressure rupture, resulting in the loss of function of the body tissues. ”

Rong Yusi nodded and said: "What you said makes sense, it seems that their skin should be very loose, at least the water molecules can pass through, how can such a loose tissue be so strong?" ”

"It's not necessarily permeable, I think water can pass through cells layer by layer, and the first thing to be destroyed is the skin." I explained.

"It's hard to say, their body strength is quite high, it is said that the cell membrane should not be so fragile, is this internal and external pressure to such a strong extent?" Rong Yusi analyzed.

I thought my speculation was correct, but I didn't expect it to stand up to argumentation, and I couldn't help but feel a little frustrated, so I said: "Don't think about this yet, you will have to dive later, so get ready first!" ”

Rong Yusi seemed to be still thinking about this question, but I suddenly thought of something. Xiaohua's plan is not only unworkable, but also very dangerous!

His plan was based entirely on not being discovered by Gega, and only on this basis could we sneak out and escape. But the small door was not tightly sealed, and the water would flow out quickly after it poured in, and the Gega in the alleyway outside the door would certainly not die at once, and it would certainly alarm those in the castle. In this way, we are in the water, they are on the shore, back to the situation before we came in, and even more terrible, this time, we will have nowhere to escape.

Thinking of this, I already shouted, and then I got up and ran out. Xiaohua has been working for a while, and with the strength he showed before, I'm afraid that he has almost done it by this time!
