After the fog dissipated, the three of them walked inside again, and after walking for a long time, they couldn't see the exit ······!

Niu Jianjun said: "Lao Guo, why is this corridor so long? ”。

Liu Lili also said: "Yes, why do I think we are going around in circles in the corridor?" ”。

Niu Jianjun said: "Let's go back, we always wander around here, and we will never be able to get out!" ”。

Guo Jiefang took a flashlight and shone it into the corridor, and found that the corridor was long and straight, as if there was no end at all. They had been walking back and forth in the corridor for more than an hour, but the corridor in front of them was like a labyrinth, trapping them firmly here! The corridor was deep and weird, like a giant python with a big mouth, about to devour them, Guo Jiefang's heart swept through a trace of ominous premonition······!

The three of them had to turn around and walk back, hoping to exit the hallway, but they walked a long way back and couldn't find an exit! The three of them were a little panicked, and Niu Jianjun said: "Lao Guo, we must be spinning in place, otherwise why can't we go out all the time?" ”。

Guo Jiefang said: "Don't panic, let me think about it!" ”。

Niu Jianjun hurriedly said: "What else are you thinking, we must have been shocked by the ghosts just now!" Otherwise, how could a good corridor not be able to get out? ”。

Although Liu Lili was also scared at this time, she understood that the more this situation was, the more she couldn't panic, so she persuaded Niu Jianjun and asked Guo Jiefang to think about it. Guo Jiefang said secretly: "This corridor, straight to the bottom, we have been walking in it for several hours, and we haven't found any forks, which can rule out the possibility of getting lost because of the forks, since it's not because of the wrong way, then what is the reason?" Is there something wrong with the corridor itself? Did the Japanese build this corridor in the first place to trap people coming in? If so, they would just have to build the hallway into a circle and then put the entrance with a trap! Then the person who walks into the corridor will be like a guinea pig, and will never be able to turn around this circular corridor! So how do I find the exit? Each section of the corridor here is the same, with no beginning or end. But we did come in from the outside, and maybe the place where we came in was the beginning and the end of the corridor! So, where is the end? How can you be sure? If the shape of the corridor is circular, it means that we have been circling in the corridor all the time, ······!

Thinking of this, Guo Jiefang asked Liu Lili to untie the scarf around her neck, and found the thread and disassembled it into a ball of yarn. The two pulled the two ends of the ball of yarn, Liu Lili stood in place, and Niu Jianjun pulled the ball of yarn and walked forward until the ball of yarn was exhausted!

Guo Jiefang followed behind Niu Jianjun and observed whether every section of the corridor through which the wool thread passed was on a parallel line! After such a section-by-section measurement, Guo Jiefang was finally horrified to find that each section of the yarn was straight and did not have any inclination! This shows that the corridor they measured was also straight and did not form a closed circle, that is, his hypothesis about the closed circle just now was not valid at all! But if it weren't, how could they not get out here?

Fortunately, when Guo Jiefang was measuring the corridor, he stumbled upon a strange phenomenon! That is, each section of the corridor is not the same length, forward or backward, the length of the corridor is correspondingly shortened! That is, the farther away from them, the shorter the length of the corridor! Why? Is there some secret hidden here? Is it possible to get out of here only by going forward or backward?

Guo Jiefang said: "Is it so easy to get out of here?" It shouldn't be like that! If I went forward, as the corridor shortened, I could not get out of the corridor, I could only keep walking forward in this infinitely shortened corridor, until finally, I disappeared into this darkness with this infinitely shortened corridor! But if you don't go forward, will you go backwards? The result should all be the same! So stop here? We will soon die of thirst, starvation, madness, and our corpses will be swollen, stinky, and crawling with maggots in a very short time, so what should we do?

In the room outside the corridor, I killed myself twenty years ago, which shows that this corridor in front of me is not the end of my life, and I should be able to get out of here alive! But where exactly is the way out? Do you want to keep going inside? But if I keep going inside, it will be eternal darkness, should I try it?

I should give it a try, for my own sake, for the sake of the people I love, and I'm not going to die here! I was killed by my current self for twenty years, and Liu Lili and I should have walked out of this underground fortress and lived for a long twenty years!

Guo Jiefang made up his mind to go to the end of the corridor to have a look, but what would the end of the corridor look like? Will the endlessly shortened corridor really disappear into time and space? None of this matters anymore, Guo Jiefang is determined to go to the end of the corridor to see!

Guo Jiefang left Niu Jianjun and Liu Lili in place, and walked towards the dark and long corridor alone with a flashlight, the corridor slowly retreated in the light and shadow of the flashlight, and each section of the corridor was the same as the previous one, without the slightest difference, but Guo Jiefang had gradually realized that the corridor was shortening little by little, and the end of the corridor was really an infinitely shrinking space as he imagined? Guo Jiefang suppressed the fear in his heart and continued to walk inside!

In front, he could already see the corridor at the other end, and there was also a person in the corridor walking forward with a flashlight, his flashlight was like a firefly, shining in the dark corridor! Although Guo Jiefang couldn't see the person's face clearly, he was very happy to meet another stranger here, because this corridor was too weird, and it was much better to have another person with him than to walk alone! He now felt a lighter than ever! Guo Jiefang hurriedly chased after the person in front!

However, the man in front seemed to sense something, and walked quickly. Guo Jiefang thought to himself: "What did he find?" Has he found a way out?' ”。

Guo Jiefang felt a burst of ecstasy in his heart, so he ran towards the man, but the person in front of him also suddenly ran! Guo Jiefang chased the man a few corridors, and the distance between the two became closer and closer. Guo Jiefang can now clearly see the back of the person in front of him, the person in front of him is wearing a yellow military uniform top, blue navy pants, and a military satchel on his back!

Guo Jiefang looked at the person's back and looked familiar, secretly surprised in his heart, and thought: "Who is the person in front?" Why is it so familiar? He suddenly "chuckled" in his heart, and secretly screamed: "It's not good······ Could it be ······ Could it be ······ Is that the person in front of me ······ myself? Have I been chasing after myself just now? So what is he chasing after the one in front of me? Is it chasing the other me? Guo Jiefang couldn't help but be shocked, but at this time, the corridor had shrunk very short, and he also chased behind the man······ Guo Jiefang just wanted to stop the person in front of him, but he hesitated at the last moment, he remembered the self he killed twenty years later! Guo Jiefang thought to himself: "I'm going to stop him, how will he treat me?" Will he kill me in the same way? No, I can't take that risk, I should get as far away from him as possible······!

Guo Jiefang immediately stopped, but at the same time, he felt as if someone had stopped behind him! He was startled, and when he turned his head, he saw that a person who looked like him was reaching out and pinching him fiercely! Guo Jiefang screamed with a frightened "ah", and sat on the ground ······!
