Sure enough, after walking for a while, the sign they had made reappeared in front of them, and the two of them stopped and looked at the sign on the wall carefully.

Now they all have a glimmer of hope in their hearts, that is, the sign on the wall is just a little similar to the sign they made, not the sign they made.

But after observing for a while, they couldn't find a different place, and they realized in despair that they had really returned to their original place.

"We're back to where we were." Hua Xinyu said at a loss.

"I know." Lin Qing looked at the sign and thought about countermeasures.

"Did we encounter the legendary ghost hitting the wall, as it is rumored outside, is there really a ghost here?"

Hua Xinyu asked and looked around in a panic, for fear that something terrible would suddenly burst out.

Lin Qingyu glanced at Hua Xinyu, and after thinking for a while, he replied: "Where is there any ghost in this world, there must be someone who is in the maze, and the so-called ' Ghost hitting the wall', in fact, in the dark environment, lack of sense of direction, unable to distinguish the direction, self-perception is blurred, do not know where to go, then it will go by feeling, and the essence of human biological movement is circular motion, if there is no goal, the instinct of any creature is circular motion, because there are subtle differences in the body structure of creatures, and the strength of people's two legs is also different, so the step distance will also be different, such as the left leg steps are long, the right leg steps are short, and the accumulation of walking down must be a big circle, so there will be the phenomenon of always turning in a circle, which is the saying that ghosts hit the wall。 ”

"But there is only one road here, although the light here is dim, but you can barely see the road clearly, and we have always walked forward, there is only one direction, how can we not tell the direction."

When she said this, Hua Xinyu had a flash of inspiration in her mind, and she suddenly understood what Lin Qing said.

"Are you saying that this passage is a circle, and we have been walking in this circle?"

Lin Qing nodded and said: "In fact, the light here is very dim, our visual range is limited, what we can see is only a small part of this circle channel, if a circle is large to a certain extent, then take its small section of the side length, then this small section of the side length is equivalent to a straight line, and in this dim environment, the perception ability decreases, which creates the illusion that we have been walking in a straight channel, in fact, the passage we are walking should be a circle." ”

"Amazing, I didn't expect you to know quite a lot." Hua Xinyu quietly gave a thumbs up and praised without hesitation.

Lin Qing glanced at Hua Xinyu again and said, "What's this, isn't this all basic common sense, if you read more books, you know more than me." ”

"Well, how are we going to get out now, you great talent, very knowledgeable person, use your clever mind to get me out of this hellish place."

Hua Xinyu looked at Lin Qing's disdainful look and felt that Lin Qing couldn't praise, at this moment she thought to herself: You just praised you and you gasped, are you despising me with this look, if I like to read, will I still fail the college entrance examination, I have already taken classes comfortably in college, where will I come out early to work hard in society, and I have suffered so many white eyes over the years.

Where would Lin Qing have thought that Hua Xinyu had so many little Jiujiu in her heart, and replied: "This place was not designed by me, how can I say that I can go out, since this place is designed like this, then this must be a place to trap people, if I want to go out, then what's the use of designing this place?" ”

Lin Qing will not be arrogant, let alone say promises that he can't guarantee.

Hua Xinyu listened to Lin Qing's crackling words, and she was a little brain-raising, in her impression, Lin Qing is not a person who talks a lot, she usually asks and answers, but she didn't expect to say so many things today, but it's okay, it's normal to talk more, if you keep the words in your heart all day long, you will get sick one day.

Looking at Lin Qing's slightly speechless eyes, Hua Xinyu felt that the current Lin Qing was much more pleasing to the eye than when she first met her, after all, Lin Qing's sad and cold aura at the beginning would always make people feel uncomfortable, and now Lin Qing, the sadness on his body has dissipated a lot.

It seems that he has slowly come out of the death of his ex-girlfriend, Hua Xinyu thought with some joy.

Looking at Lin Qing's side face, she felt that although Lin Qing was not very good-looking, she was quite manly, and looking at it, she suddenly felt a little distressed about the man in front of her.

Originally, Lin Qing would have a beautiful girlfriend to accompany him, spend a simple life sweetly, taste the firewood, rice, oil and salt of life together, and spend the spring, summer, autumn and winter of this wonderful world together, but the world is impermanent, and a car accident has torn this life apart.

The girl's mind is a little flustered, in this situation at this moment, Hua Xinyu is not thinking about how to get out, but thinking about what happened to the man in front of her, if Lin Qing knew her thoughts at this moment, she would be speechless.

It's all about time, and I'm still feeling sad.

Just when Hua Xinyu was thinking wildly, Lin Qing turned his head, and the eyes of the two met in the dim light, looking at each other's eyes, both of them had a strange feeling.

Both of them seemed a little embarrassed, and after making eye contact, they slowly parted again, pretending that nothing had happened.

Lin Qing first broke the embarrassing situation, looked away and asked, "Do you remember the stone gate we just came in and encountered?" ”

"Remember, what's wrong, the door closed as soon as we entered." Hua Xinyu lowered her head and replied, her covered face was still a little red.

When she was looking at Lin Qing just now, she was shocked by Lin Qing's charming eyes again, and she was a little embarrassed for a while.

She had to admit that although Lin Qing's face didn't seem to be very handsome, Lin Qing's eyes were indeed good-looking, and when she frowned, the seriousness between her eyebrows gave people a sense of solemnity, and her eyes seemed to be filled with endless stars, bright and deep; After stretching his eyebrows, his eyes are like two clear springs, and a slight touch of his eyes seems to be able to moisten people's hearts and wash away all dust.

After looking at Lin Qing's eyes a few times, she always felt that Lin Qing's eyes were very familiar, and they were the same type of eyes as his idol Man Qingyun's eyes.

Lin Qingke didn't know what Hua Xinyu was thinking, and his voice sounded again, interrupting Hua Xinyu's thoughts.

"Yes, it's the stone gate, don't you think it's strange, we came in from the stone gate when we came in, so, how did this passage form a circle, since it was a circle, then after we walked a few laps, why didn't we see the stone gate again?"

"yes, what's going on?"

Lin Qing's words also aroused Hua Xinyu's curiosity, she threw away those messy thoughts, and frowned and began to think.

After thinking for a while, Hua Xinyu said tentatively: "Could it be that the walls here will move, and the walls will be moved to close the position where we just came in?" ”

Lin Qing thought for a moment, nodded, and said, "There is also this possibility, there must be another mystery in the walls here." ”

Lin Qing approached the wall as he spoke, and began to grope around, and Hua Xinyu also learned from Lin Qing to search on the wall to see if there were any mechanisms.

The tunnel was a little damp, and the air seemed to be filled with water vapor.

The walls were also a little wet, and moss had grown in some places.

After the two groped for two hours, they found that they had not found anything, and they couldn't help but feel a little anxious, and their despair gradually rose, and their uneasy expressions slowly climbed up their faces.

The two of them tossed for so long, they were already physically and mentally exhausted, Hua Xinyu found a relatively dry place to sit down, and asked weakly: "How long have we been here, can we still go out, we won't die in this place, right?" ”

Lin Qing also sat down and said, "Don't think nonsense, we will definitely be able to go out, since we are tired, then let's rest for a while." ”

Although he said so, his face was also full of tiredness, and he couldn't say if he could get out, but he still had a lot of things to do, and he didn't allow himself to be trapped in a tunnel like this, so he had to lift his spirits and try to keep those negative emotions away from him.

Hua Xinyu looked at Lin Qing, smiled bitterly, and then turned her head to look at the top of the tunnel, where there was a place at the top where water was constantly dripping, and the water droplets were constantly dripping on the ground of the tunnel, making a crisp ticking sound.

She thought about a lot of things in that moment, and she imagined how sad she would be if she couldn't get out and her parents couldn't find her.

If she really disappeared in this world, how many people would think about looking for her, forget it, she was a little lonely and found that maybe it was only her parents, and if she calculated it carefully, at most, she would add Qin Min and Shu Jing, and maybe Lin Qing who was sitting next to her, but she wasn't sure if Lin Qing would really look for her after she disappeared.

Although she asked Lin Qing for help, Lin Qing would come to help her every time, but she also knew one thing, that is, she and Lin Muxue were very similar, like carved out of a mold, Lin Qing would help her, maybe it was because of Lin Muxue, because of the woman he loved deeply, thinking about it, her mood suddenly became a little gloomy.
