Yu Shan instinctively gasped and closed his eyes in an attempt to calm himself down, while he began to recall the factors that might have caused him to hallucinate. His name is Yu Shan, Yu is Yu Zilulu's Yu, and Shan's is Xiao Shan's pine. Seven months later, he is about to celebrate his 35th birthday, and the once promising yard farmer is now a primary school physical education teacher who is waiting for death. Smokes a small amount and never drinks alcohol. There is no history of mental illness, and the family has not heard of any crazy people.

Wait a minute...... It seems that he had suffered from autonomic nervous disorder in his sophomore year. At the beginning, I carefully investigated the bottom of the hospital and finally concluded that it was because Yu Shan was not adapted to the climate of Bingang and therefore lacked sleep caused by autonomic disorder. However, the autonomic nervous disorder has neither auditory nor visual hallucinations, and at most the tinnitus is severe and has some headaches. Besides, I haven't had a recurrence since.

“…… Heart-to-heart appointment~Heart-to-heart appointment~Year after year~No matter how close you are~Heaven~......"

In the noisy traffic, the damn song "Meet in 1998" still hit Yu Shan's ears. He exhaled slowly, and opened his eyes the next second.

The 'Dongdong Game Hall' was in front of me, and the two little children in the uniform of the twenty-third junior high school squatting at the door were smoking cigarettes and discussing with their eyebrows, and words such as "Yagami", "Red Pill" and "Nirvana" were occasionally passed in the comparison; The Santana 2000 had already driven far away, and Minada was stopped by his aunt who was carrying a vegetable basket diagonally in front of him. After some bargaining, the aunt finally shouted, "Who will take three wheels with the taxi" and then walked to the bus stop at the corner of the street, and a group of chirping middle school girls walked in a horizontal row on the right, one of whom was carrying a long-lost bottle of carbonated drink, Sheferi!

Everything seems so real, but for Yu Shan, it is so unreal. He turned around blankly and looked at the door he had walked out of. The white iron door, which has been peeled off its patent leather, has a large inscription in red paint that reads, 'Dumping of garbage is prohibited here'. He jerked to his left, and a few blocks away, the iconic Cathay Pacific Tower was gone, and the civil aviation building, which was only nine stories high, stood out among the low-rise buildings.

"What the hell is this?"

Yu Shan's scalp began to tingle. He turned, forced himself to calm down, and strode towards the game hall opposite. Before he left his steps, he hoped that it was all just a mirror. The next moment, if you miss it, you will be back in front of a small duplex high-rise. However, what made him desperate was that until he walked through the narrow street, the scene before him did not change in the slightest.

No, as he walked, his tracksuit that was a little out of touch with the era attracted the attention of passers-by.

Crossed over! The glass windows of the game hall reflected his figure, and Yu Shan could see that his height and body shape had not changed in the slightest. According to popular saying, that is, he is not born again, but ...... Crossed over! I walked through the back door of the video store and came to this ...... A time and space not far from the ninety-eight year.

"What the hell is it!" Confirming this, Yu Shan panicked. He couldn't wait to rush across the street, open the door, and confront Josie.

That's right, Jos...... The guy seemed to have said something to himself.

"If you don't believe what you see, bring something back."

Yes, bring something back!

Yu Shan looked left and right, and immediately saw the grocery store two doors away from the game hall. He walked briskly over and slipped past the woman at the door who was using a grocery pay phone to get into the grocery store. There were a variety of glass containers lying across the line, and Yu Shan could see the boxes of cigarettes on the far left at a glance.

"What do you want, big brother?"

Eldest brother? It's okay to call it that way now, but when my brother goes back, I'll have to call you Aunt in turn. Of course, this is not the point, the point is that Yu Shan saw the peony cigarette next to Ashima at a glance.

This is a peony, and there were more than 1,000 pieces of fried for a while, and you may not be able to buy it if you have money.

"Let's have a box of peonies!"

The woman neatly took out an open peony from a pile of cigarettes behind her, took out a box and put it on the counter. "What more?"

"Nothing else." Yu Shan pulled out his wallet and was stunned for a moment, then remembered that this was the wallet that Joss had given him. He took out ten dollars and handed it over. The woman opened the box of money and made change, six dollars and five, one piece of five, one piece of money, and five cents of the stacked banknotes.

Yes, stacked up for five cents. Yu Shan's eyes were straight when he looked at the two cents exposed outside. This thing is out of print for a long time! In a moment of thought, he unfolded the stacked banknotes, one for one and two for two cents.

The woman behind the counter was unhappy: "Big brother, look at you carefully, how can I send you two cents?" ”

Yu Shan didn't take a stubble, grabbed the change and stuffed it into his pocket, took the cigarette and walked out. Behind him, a woman's dissatisfied mutter, "This person is really interesting." ”

Yu Shan didn't have time to worry about women, he almost ran through the street at a running speed, and before he could open the door, he suddenly stopped. Fumbling for the key from his pocket, he stood on tiptoe and carved a # symbol on the red brick wall above the lintel. Then he opened the door, feeling like it had shrunk hundreds of times and thrown into the toilet bowl like his own, flipping and dizzily past the door, and stumbling into the hallway.

Standing up against the wall of the hallway, Yu Shan walked towards the store.

Joss was still sitting on a chair by the bar, just as she was before Yu Shan left. He was turning his head to look at Yu Shan, and his voice was hoarse as a torn rag when he spoke.

"How does it feel?"

"I don't want to talk to you right now!" Yu Shan's cerebellum gradually returned to normal, rushed out of the video store, ran around the back street, and arrived at the back door of the video store. He gasped and looked up, and saw a vague and mottled # symbol carved on the red brick wall above the lintel. He took out the change and the deflated pack of peony cigarettes from his pocket, and finally confirmed the fact that he was least willing to believe.

That's right, he had just crossed over, and the moment he passed through that door, he suddenly went back to the past from the present!

Curious, frightened, excited, puzzled...... All kinds of emotions were mixed together, and he gritted his teeth and tentatively stretched out his right hand to open the door again. Strangely, this time there was no strange feeling, he walked smoothly into the hallway, and also saw Joss sitting in a chair at the end of the hallway.

Joss said weakly: "I have tried it a long time ago, and when I opened it from the outside, nothing changed. ”

Yu Shan casually closed the door, walked through the corridor and stood in front of Qiao Si, and asked loudly, "What the hell is this?" ”

Qiao Si glanced up at him and said, "Lao Yu, you are smarter than me, and you have also gone to college, you should know such an obvious thing very well." ”

Yu Shan pointed to the door and shouted, "Why do you want to tell me that this is a space-time gate?" If you walk there, you can travel to the 19th ...... Uh, more than a decade ago? ”

"It was 1998. And besides—" He looked at the door at the end of the corridor and said, "-- I prefer to call it the Gate of Yesterday." ”

Qiao Si's explanation couldn't alleviate the confusion and panic in Yu Shan's heart at all: "What the hell is going on?" ”

"I don't know what's going on." Joss shook his head and whispered, "You know that the back door of the store was chiseled open by a bunch of bastards three years ago. ”

"Well, I accompanied you to report the case in the first place."

Joss added, "Yes, that's right. Then, with a sigh~, it appeared so suddenly. The first time I walked through, I was even more panicked than you. ”

"It's as simple as that?"

Joss spread his hands, his eyes sincere, and signaled that he was just telling the truth.

But Yu Shan couldn't accept this explanation at all: "How come? ”

"I don't know. Maybe it's because of the second-hand market-bought security door. ”

Yu Shan's heart turned upside down, countless doubts came to his heart, but he didn't know how to speak for a while. Joss on the other side poured himself another glass of water, took a few sips, and said, "Now I'll answer the question you asked me a few months ago." ”

"What?"

"This shop has been operating at a loss and can survive to this day," Joss looked at the door with a complicated gaze, "It's because of this door." ”

I see! This explains why Joss shouted that he was losing money, and at the same time sold those cherished records at prices below the market price.

"Still have questions?" Joss said.

Yu Shanran shook his head.

"Alright, now let's get down to business." He straightened up and leaned his back against the bar. "Originally, I was going to keep this secret and use it to do some ...... Something that changed his life against the sky. But as you can see, I don't have a few days to live. ”

Yu Shan wanted to say something, but was interrupted by Qiao Si as soon as he opened his mouth: "Don't waste time comforting me, you can't be more professional than a doctor." After a pause, he said, "I leave this door of yesterday, including this shop, to you." ”

"Leave it to me?"

"I don't have many relatives and friends, just a few people who know the roots, and you are the one who can make me trust. The following words must be listened to carefully, there are no restrictions on passing through this gate of yesterday, and I have tried to summarize its rules. Rule 1: After traveling through the past, no matter how long you stay there, you will come back and find that only two minutes have passed. The reverse is also true, no matter how long you stay here, you will find that it has only been two minutes since you last left;

Rule 2: Don't make easy contact with people in that plane, and don't change what should happen. History seems to have inertia in the ******, and when I try to change something, I always encounter all kinds of accidents;

Rule three, if you change the history that affects your original memory, you will have a severe headache when you come back. There will be an additional memory in the memory that is related to the change of that event. These memories appear as if they appeared in the mind out of thin air;

Rule four, to the plane over there, we're like a virus smuggled into its body. You know very well how your body will deal with the virus, yes, immunity. The longer you stay there, the more and more accidents will happen to you. So if you want to come back alive, you better trust me, and you must not stay for more than four weeks;

Rule five, this one is simple. Where you left and where you come back, if you want to travel back and forth between the two planes, this door is the only passage;

Rule 6...... And the most important one. Forever, Forever...... Never get close to your past self. ”
