"Really? That's great, we just need to check the room number to avoid the room with the mechanism, right? I asked happily.

"I'm not sure about this, do you have any paper? I wrote down the code of the room I walked through, and drew the road map by the way. Shu Muhua said.

I took out the notebook and pen from my backpack, and then handed it to Shu Muhua, who wrote down the codes of the rooms we had walked through before, and then drew the route map.

"According to your road map, we have walked more than ten meters down, and overall, we are still in the right direction." I took the notebook handed over by Shu Muhua, looked at it and said.

"It's going down, but no one is sure that the bottom is right, so we'll have to walk a little further to find out." Shu Muhua said with a frown.

I nodded, and then checked the codes of those rooms, and sure enough, they were all "prime numbers", and I thought that I was finally a little bit of an eyebrow, and if I went on like this, I would definitely reach the end, but I didn't know what would wait for us at the end.

"Then let's move on, and first eliminate the rooms with prime numbers, so that we can save a lot of time." I then said.

Then, I told everyone to look at the room code around them, and if they found that they were prime, then test the room first, and if it was safe, then pass.

In fact, Shu Muhua, Xie Xinyi and I can check the room code, the fat man and Ye Ming are really stupid, fortunately, Shu Muhua's mathematical talent is really good pervert, it didn't take long to find out a room with all prime numbers, after finding out, throw the shoes, and then let Ye Ming go in first, if it's safe, then we'll pass.

Sure enough, through this method, we quickly passed through a few rooms, which also greatly reduced the probability of Ye Ming's accident, and I felt a little better in my heart, in fact, I still struggled a little in my heart when I started to make this decision, but after all, we had limited food, and we couldn't leave Ye Ming alone, so we could only come up with such a way that was not a way, if Ye Ming was fine, it would be regarded as a contribution for us, and give him some food, and everyone would not have any opinions, if Ye Ming had an accident, we can't be blamed, After all, if he goes on his own, the probability of survival is much lower, and if he dies, we will lighten the burden.

As we pass through more rooms safely, everyone's mood is no longer dull, the fat man will occasionally joke with Xie Xinyi, I am still the same as just now, check the code of the room, with the continuous calculation, the brain has also become better, the current code of this room is "103,367,421", I calculated for a minute, basically determined that this is a set of prime numbers, and hurriedly called them to come and test this room.

The fat man threw his shoes in, and didn't find any mechanism that was touched, so we let Ye Ming go in first, Ye Ming jumped in with ease, and walked so many rooms in a row, and there were no accidents, so he was much more relaxed than at the beginning, but as soon as he walked to the middle of the room, he suddenly stopped and didn't move.

"What's going on?" I asked, a little nervously.

Ye Ming didn't talk, but looked ahead in a daze, suddenly, he jumped to the right, I just found out that around him, I don't know when there was a thin net that was difficult to find, the fine net suddenly shrank, fortunately he found it relatively quickly, otherwise, it would have been crushed by the fine net.

This thin net is very sharp, the moment Ye Ming jumped out, his calf was still scraped, and the blood flowed, he screamed and hid aside, and the fat man and I hurriedly jumped over and carefully pulled him out.

Shu Muhua bandaged Ye Ming's wound, and the fat man and I discussed the accident on the side.

"Long Shao, can you do it? Is it a miscalculation? Is this a prime number? The fat man asked me a little skeptically.

"Impossible, I've counted it several times, it's definitely a prime number." I said with a frown.

"I also looked at the number, it's a prime number, yes." Xie Xinyi also said on the side.

"That's weird, it seems that the law just now is invalid, so be careful." I said a little frustrated.

Shu Muhua had already finished bandaging Ye Ming's wounds, and he hurriedly walked over, "What's the matter?" Isn't that room code prime? ”

"The law is broken, uncle." I said to Shu Muhua helplessly.

"Then take a look at the other rooms." Shu Muhua then said.

As a result, we tested the remaining rooms one by one, and all the rooms with prime numbers had mechanisms, and only one room without prime numbers was safe.

"Could it be that the next room, so the prime numbers are all organized?" Shu Muhua looked at the numbers he had written down and said to himself.

"Let's go into this room where it's not prime first, if it's safe, then let's go through a few more rooms and try it, we can't make a conclusion yet." I then said.

"It's hard to say, just let him go in and try it." The fat man said on the side, and after speaking, he pointed at Ye Ming.

"Big brother, I'm injured like this, and you still let me in? I don't go in. Ye Ming shook his head like a rattle, saying that he wouldn't go in, it seemed that the mechanism just now had caused him a shadow.

"Hey, you want to regret it, don't you? Then you are waiting here to die! The fat man said angrily.

I saw that Ye Ming's calf injury was indeed a little inconvenient, and it was a little unbearable to let him in again, so I said, "Let me come." "Then we will drill a hole.

Xie Xinyi grabbed me on the side and said softly, "Be careful." ”

I nodded at her, and then I got in, I carefully pressed against the wall, and then slowly walked around, no accidents were found, I moved to the middle of the room, slowly, and there was no mechanism touched, it seemed that the room was safe, I hurriedly shouted over there: "Come here, it's safe here." ”

Then, they all came over one after another, and in this way, we walked through several rooms in a row, and sure enough, as long as there are rooms with prime numbers, they all have mechanisms, and rooms without prime numbers are safe.

I don't know how long it took, my stomach began to growl, I guess if it was outside, it would be dark, no one in there had a watch, the dead mirror fat man was wearing a watch, but before he could return it to the fat man, he encountered a zombie.

I suggested that everyone stop and take a break and eat something, I checked the food in my bag, there were five of us, it was enough to eat for a day, and if we couldn't get out again, it would definitely be dangerous.

"There's not much food left, so I suggest everyone save some food." I spread out my backpack for everyone to see.

"You don't care, I'll divide it." After the fat man finished speaking, he pulled his backpack over.

He walked to Shu Muhua's side first, "You are old, eat less, and after speaking, he gave Shu Muhua a military canned food and a bottle of water." ”

"Cheng, I still have some of my own bread here." Shu Muhua took it with a smile.

The fat man walked over to Xie Xinyi again and gave her a military can, "Big beauty, lose weight, you should eat less." ”

"Hehe, I'm not hungry, thank you." Xie Xinyi smiled and took the can.

The fat man took out another can, a cake, and a bottle of mineral water, and then returned the bag to me, "I consume a lot and am a new force, so I need to eat more." With that, he sat down and ate.

"Fat brother, you are really thick-skinned, but considering that you have to contribute more in the future, let's accommodate you." I said with a smile.

"That, Long Shao, don't you also give me some food." Ye Ming said while rubbing his hands.

"You? Come aside, you're the one who is dragging your feet, and you still want to share our food? The fat man chewed the food in his mouth, said loudly, snatched my backpack after speaking, and then said: "Long Shao is too merciful, this food, I will look at it in the future." ”
