Meng Zhoushan didn't go back immediately after buying the flower. Standing on the bustling street, he watched the boy in a wheelchair finish shopping skillfully and with difficulty through the crowd, then pushed the rollers with both hands, and left this crude market made up of various stalls.

Afraid that he would be knocked down by passers-by, Meng Zhoushan followed him from a distance until he saw the boy entering the elevator, then he appeared from the corner of the corridor and walked slowly towards the elevator.

He thought the elevator doors should be closed.

He didn't intend to take the same elevator with the boy, so as not to show that he was too deliberate.

However, when Meng Zhoushan stopped at the door of the closed elevator and was about to press the button, he found that the elevator was still on the first floor and hadn't gone up. His fingertips couldn't help but pause.

With a sound of "ding", the elevator door suddenly opened slowly.

Sui Yuesheng sat on the wheelchair, watching him quietly. On his lap were several plastic bags containing the vegetables he had just bought. When he saw Meng Zhoushan, he hesitated and asked, "Aren't you coming in?"

He kept pressing the door open button with his fingertips, and then softly added two words: "Shúshu..."

These two words seem to have some other meaning, which is unclear.

Meng Zhoushan paused after hearing the words, then walked into the elevator: "Thank you."

He was thinking about when the teenager found him waiting outside.

"It doesn't matter."

Sui Yuesheng pressed the close button. He noticed that Meng Zhoushan was holding a potted flower in his arms, but it hadn't sprouted yet, and he couldn't tell the variety, so he couldn't help but look at it a few more times.

Seeing him staring at the flower pot in his hand, Meng Zhoushan couldn't help but also lowered his head to take a look: "Just now I saw someone selling it on the side of the road, so I bought a pot."

Sui Yuesheng hummed: "I know, ten yuan a pot."

The stall owner always collects flower pots that others don't want, fills them with soil from roadside flower beds, stuffs them with a few melon seeds, and then sells them. The cost may not even be a few cents.

Residents nearby know that whoever buys it is a fool.

Meng Zhoushan quite liked this potted flower: "This is a sunflower."

"He lied to you," Sui Yuesheng said, "the stuffed inside are ripe melon seeds, which won't sprout."

Meng Zhoushan was stunned for a moment, he subconsciously looked at Sui Yuesheng, but he could only see the young boy's handsome side face and thin pointed chin. Falling into silence for no reason.

Sui Yuesheng suddenly smiled: "Just kidding, I lied to you..."

No one knows if it's because of the dim light of the elevator, but the light reflected in his eyes gave him a faint light: "Take care of it well, it will bloom."

The elevator had arrived, and the double doors opened slowly, revealing the long and dilapidated corridor. Meng Zhoushan adjusted the gold-rimmed glasses on the bridge of his nose, then handed the flower pot to Sui Yuesheng, walked to the back and pushed him out of the elevator: "Kiddo, it's not a good habit to lie to others."

His voice was low, and the light cologne on his body smelled good, in stark contrast to the decaying musty smell in the corner.

Sui Yuesheng pursed his lips when he heard the words, inexplicably feeling a bit cramped. It wasn't until they were about to separate from the left to the right at the intersection of the corridor that he reached out to hold the potted flower and handed it to Meng Zhoushan: "Your flower..."

Because he was sitting in a wheelchair, this action made him look a little strenuous. The sleeves of the ill-fitting clothes slid down because they were too wide, revealing two bruised arms.

Thinking of his family environment, Meng Zhoushan seemed to have guessed something, his eyes paused slightly, and then he squatted down in front of the young man, at eye level with him, and said with a smile: "I'm not very good at growing flowers, this pot is for you."

Meng Zhoushan said: "I will live here for a long time. If you grow it to bloom, I can grant you one wish...any wish."

He appears to be coaxing a child, and he seems to have buried a flower seed representing hope in the rotten and damp mud. In the long and dark time to come, the high walls closed on all sides were cut to let in a ray of skylight.

Sui Yuesheng didn't speak, and maintained that posture without moving, overlapping with the scene of their last meeting in the previous life.

Meng Zhoushan stood up straight and pointed to his own door: "I will live there. If you have nothing to do, you can come over as a guest at any time."

Sui Yuesheng's eyelashes trembled when he heard the words, and finally slowly withdrew his hand holding the flowerpot. He lowered his head and unconsciously touched his broken leg. When he looked up again, Meng Zhoushan had already left.

"..."

The hallway was silent.

Sui Yuesheng carefully placed the flower pot on his knees, and pushed the wheelchair back home. When passing by the stairs, He glanced up, and no one knew what he saw, but he slowly stopped his movements.

The corner of the stairs was dark, and a dirty red mop was quietly leaning on the corner. The strips of cloth are long and thin, like a woman's hair in the dim light.

Sui Yuesheng looked at it for a moment, then suddenly smiled. He withdrew his gaze, rolled the wheelchair back home.

A drunk man was lying on the sofa in the narrow living room. He held a half-burned cheap cigarette under his fingertips. The gray ash fell all over the floor, which was pungent and smelly. The old TV was showing the new season of a game, and the signal was intermittent and rattling.

There was also an obese teenager lying on the bed playing games, his lips were abnormally dark purple.

Sui Yuesheng pushed the wheelchair into the room, and called the man on the sofa: "Uncle."

Chen Pingchuan kept staring at the TV without even looking at him. Hearing this, he frowned impatiently and said, "Why have you been shopping for so long? The next door has finished eating, hurry up and cook."

Sui Yuesheng hummed, and pushed the wheelchair to the narrow kitchen aisle. He bent down and carefully placed the potted flower on his knee in the corner, and then began to wash vegetables and cook. Fortunately, the stove was low, so it wouldn't make him too strenuous.

Not long after, a thin middle-aged woman opened the door and came in from the outside. Her long hair was held up in a plastic clip, her eyes were sunken, her cheekbones high, and she looked utterly mean. She shook the change cloth bag in her hand, the coins in it rattled, and she put her hands on her hips and cursed: "I really shouldn't have gone to the chess and card room of that stupid old man Hu's house, he cheated behind his back, causing this Laozi to lose more than ten yuan."

Chen Pingchuan was annoyed when he saw her: "Play cards and shit, you only know how to play cards all day! Can you go out and find a job if you have some free time?! Your son is going to have an operation soon, and the money hasn't been saved up yet!"

Wang Suying's voice was sharp: "It's my son? isn't he also your son?! Chen Pingchuan, as long as you man up, we won't be like this. You only have such a small salary a month. What are we going to do with that?! Go support the beggars!"

The boy who was lying on the bed playing games suddenly cried out, "Mom, am I going to die?"

Wang Suying immediately stepped forward and hugged him into her arms, patting and coaxing him: "What nonsense, Akang is mother's heart, and if you don't live, mother won't live anymore. Mother worked so hard to give birth to you. The operation fee will definitely be..."

Chen Pingchuan became even more irritable when he mentioned the operation fee: "Yes? Where should we get it? I have sold several houses, and it is a bottomless pit. You want me to earn the operation fee, what daydream!"

When he said this, he was completely unaware that those houses were the inheritance from the Sui family to Sui Yuesheng.

Sui Yuesheng buried his head in the cooking, never seeming to listen to the loud and unpleasant scolding, and finally the farce ended with Wang Suying being slapped in the face.

She didn't dare to fight Chen Pingchuan, so she went to the stove and pinched Sui Yuesheng twice: "You fucking useless brat! You can't walk with a broken leg, and you can't even cook faster, what are you doing!"

The woman's fingernails were pointy, and when she pinched them through the thin clothes, his flesh was torn.

Sui Yuesheng remained silent.

During the meal, Wang Suying added a big bowl of rice to her son Akang, and fiddled with the two dishes on the table. Like picking pearls from the sand, she rummaged through the scattered bits of lean meat, and put them all into her son's bowl.

Chen Pingchuan slammed his chopsticks angrily: "Wang Suying, if you don't want to live with it, we can get a divorce! Just buy such a little meat and feed it to the beggar!"

The last sentence was to scold Sui Yuesheng.

Sui Yuesheng's bowl was clean, except for a small spoonful of rice. He was used to being scolded. He neither was served food nor drank water, and ate the sporadic meals with his head buried.

At that time, Meng Zhoushan came home, cooked some pasta to pad his stomach, and then sat at the desk and began to write his own narrative. The golden pen glides over the white paper, leaving behind ink marks:

[I lived in this dangerous building again, and everything is still the same as before. It's like going back in time, back to the very beginning. This time, I have one more chance to find out the truth.

People always look for answers after the crimes have happened, but most of the incidents have no trace, because the truth is sealed in the mouths of the dead, and no one can restore the fragments unless time goes back.

I love true stories. How it happens, how I record.

This time I was at the forefront of time. Whether it was the murders that happened back then, or the clues about ouroboros, a gap was finally opened.]

Meng Zhoushan writes here, the tip of the pen slowly stops. He was slow to realize that the narrative tone of these texts could easily cause misunderstandings if others saw them, so he hesitated for a moment, then blackened them with a pen and threw them into the trash can.

The system landed on the corner of the table:【Dear host, congratulations, the villain's blackness has been reduced to 99.99%】

Meng Zhoushan habitually adjusted his glasses on the bridge of his nose, stared at the system quietly, with a bit of exploration and scrutiny: "Is there any difference from before?"

System:【Of course, the degree of blackening has dropped by 0.0099%!】

The system doesn't know if it's because it has experienced too much, but the system calms down inexplicably. Its diamond-like body is dazzling under the light, but a small piece is missing for some reason.

Meng Zhoushan couldn't help taking another look: "Are you missing a piece?"

The system was shy and turned into a pink diamond:【It was accidentally picked away.】

At this point, it suddenly remembered that it seemed that it had forgotten to tell Meng Zhoushan something. It's all because the other party died too early, and it didn't have time to say it, but it seems too late to say it now.

How should I speak?

Hello, my previous host wants you to help pay back his debt?

In view of the particularity of "Dangerous Buildings", which is equivalent to a memoir, Meng Zhoushan is actually not a book transmigrator in a sense, but a rebirth. The system counted on its fingers, and finally decided to tell Meng Zhoushan when it was about to leave this world, anyway, it's all the same.

Meng Zhoushan didn't know what the system was thinking. He turned over a page and wrote a sentence on it with a pen that no one else could understand:

[Nine o'clock in the evening on the 26th, the seventh floor, the first snake.]

If Meng Zhoushan remembers correctly, the first murder case in this dangerous building happened at nine o'clock in the evening on the 26th. The deceased was a lecherous old man who lived on the seventh floor. His favorite thing was to roam the streets in a scantily clad tank top and shorts, spying on young girls.

His body was not found until three days after his death, and a picture of ouroboros was drawn on the wall of the murder scene. This is also the first beginning of the serial murder case.

Meng Zhoushan looked down at his watch. Today is only the 23rd, and there are three days left.

Yan Yuezhao is the criminal policeman in charge of this jurisdiction. Meng Zhoushan picked up his cell phone and originally wanted to call the other party to remind him, but he couldn't explain how he knew about the murder case, so he could only send a text message: [8 o'clock in the evening on the 26th, come here to treat you to dinner.]

Yan Yuezhao quickly wrote back: [Depending on the situation, I will go if I am not on duty.]

At this time, Yan Yuezhao divorced his wife half a year ago because he was busy with work and could not take care of his family. A rough man with a seven-year-old son, who is both a father and a mother, can be said to be in a state of desperation.

Meng Zhoushan didn't really expect him to come.

Throughout the afternoon, Meng Zhoushan sat at his desk reviewing the murder case that happened that year. The deceased were of different ages and genders, and the only thing they had in common was that they all lived in this dilapidated building, and their bad habits were hard to change.

He drew a picture of ouroboros on the paper, lost in thought. This pattern is very common in religious mythology, and is synonymous with immortality and perfection. It symbolizes the cycle and the cycle of life.

But ouroboros can't move, because it can only exist in one place, spinning in a ring forever.

Meng Zhoushan remembered the flyer handed to him by the attacker, with a sentence printed on it:

I devour sin, I gain eternal life.

I was born perfect, and I am endlessly reciprocated.

Sounds like some kind of idea used to brainwash people.

Meng Zhoushan took off his glasses and pressed the bridge of his nose tiredly. Not knowing if it was an illusion, he glanced casually, and suddenly saw a black shadow flashing above the window glass, and he couldn't help but pause.

Meng Zhoushan put on his glasses again, went to the window and opened the curtain, looked up, but there was nothing unusual. He has poor eyesight, so he can only attribute the dark shadow just now to his own dizziness.

The building was very quiet when it was quiet, and very loud when it was loud. Meng Zhoushan finished packing his manuscripts and was about to take a rest when he suddenly heard a faint noise from the outer corridor, mixed with the sound of glassware smashing to the ground.

He opened the door and went out to take a look, only to see a woman with a mean face crying and red eyes running out from the other end of the corridor, holding an obese boy tightly in her arms. While pressing the elevator hard, she turned her head and cried loudly: "Chen Pingchuan! You useless thing! You know you're crazy when you're drunk! Don't think that Laozi will continue to live with you!"

"Boom--! "

It was the sound of wine bottles smashing against the wall, and the glass splashed everywhere. At the end of the corridor, Chen Pingchuan's drunken curse could be heard, and the whole building could hear: "Go fucking away!"

Then there was the sound of the door being slammed shut.

The boy raised his head from his mother's arms: "Mom, where do we live?"

Wang Suying hugged him tightly: "Akang, good boy, mother will take you downstairs to the chess and card room to sit for a while, and wait for your father to wake up from the beer."

Meng Zhoushan skipped over the mother and son, strode towards the end of the corridor, only to see Sui Yuesheng outside alone, shut by Chen Pingchuan. On a chilly night, he was only wearing a thin white short sleeve.

Seeing this, Meng Zhoushan stepped forward, knelt down slowly in front of him, and asked in a low voice, "Did you quarrel with your family?"

He can only use such a reason that does not hurt the other party's self-esteem.

Sui Yuesheng didn't expect him to come, and was stunned for a moment. Then he shook his head silently, lowered his head and slowly clenched the cloth on his knees, his knuckles turned blue because of the excessive force: "No..."

Because of the wide collar, Meng Zhoushan saw a few bright nail marks on his shoulders and bruises on his arms from being smashed by wine bottles. He paused and said, "It's cold outside, why don't you come to my house?"

After he finished speaking, he suddenly felt that such words were very similar to the strange man abducting ignorant children, and could easily be mistaken for perverts. Just about to explain aloud, Sui Yuesheng spoke cautiously: "Can I...?"

His skin was too pale, so his eyes became darker and darker. At this time, there were two faint lights flashing inside, like flames in the cold wind, which would go out as soon as the wind blows, hiding hopes that only he knew.

Meng Zhoushan paused, then smiled: "Of course."

He stood up, walked behind Sui Yuesheng, and pushed the wheelchair towards his home. When passing by the stairs, he suddenly noticed a red mop in the corner of the steps, and felt a strange feeling in his heart.

Sui Yuesheng raised his head to look at him as if aware of it, his black hair complemented his fair skin, and he looked very cute: "Shúshu, what's wrong?"

Meng Zhoushan came back to his senses and shook his head: "It's okay."

He pushed Sui Yuesheng to the door of his house, then opened the door with a key, pushed the boy in, and closed the door gently behind his back.

Meng Zhoushan's life is very particular. Even if he moved to this dilapidated place, he still decorated the room elegantly and cleanly. Compared with Chen Pingchuan's messy home, it's like heaven.

Sui Yuesheng looked around, his eyes fell on the table with piles of manuscripts, then on the leather sofa chair opposite, and finally looked out of the window, paused slightly.

Meng Zhoushan probably didn't go out very much for half a month since he wrote the manuscript, so he stocked up a lot of ingredients in the refrigerator. He didn't know what Sui Yuesheng liked to eat, so he took some chocolate and potato chips that children like to eat, and poured him a cup of hot milk.

"looking at what?"

Meng Zhoushan handed him the milk, and was afraid that Sui Yuesheng would be cold, so he turned on the warmer. After all, this city is not so warm.

Sui Yuesheng took the cup with both hands, and said thank you in a low voice. The temperature of the milk is just right, neither too hot nor too cold, and it warms even the cold fingertips. He rubbed it for a moment, then looked up at Meng Zhoushan: "Are you a writer?"

Meng Zhoushan took off his suit jacket, put it on the sofa, and sat down behind the desk. He was wearing only a white shirt with sleeves rolled up to the elbows, and the gold-rimmed glasses on the bridge of his nose looked very refined.

He pulled out the cap of the pen and hummed after hearing: "Amateur writer."

Sui Yuesheng smiled: "No wonder you don't go out much..."

Meng Zhoushan didn't hear what he was saying, and continued to sort out his old drafts, correcting typos. He would smoke habitually when his mind was blocked, and today was no exception. However, when the cigarette was half burned, he suddenly realized that there was a child in his room.

Meng Zhoushan paused with his fingertips, and then extinguished the cigarette. He raised his hand to disperse the smoke, and apologized to Sui Yuesheng: "I'm sorry, the smoke is too stuffy."

On Sui Yuesheng's lap was the tablet that Meng Zhoushan handed him. He has never had a chance to play with this kind of electronic product, not even a mobile phone, and Chen Pingchuan and his wife would never buy it for him. Hearing this, he raised his head and said, "It's okay."

Unlike the low-quality cigarettes that cost a few dollars in Chen Pingchuan's hands, the cigarettes smoked by Meng Zhoushan are not pungent, and have a mellow feeling. He held a cigarette between his fingertips, and when he lowered his head to write the manuscript, he looked so serious that people couldn't take his eyes off it.

Sui Yuesheng asked: "What story are you writing?"

Yours.

Meng Zhoushan glanced at him, swallowed those one word, then shook his head with a smile: "What I wrote is not suitable for children to read."

It was too bloody.

Sui Yuesheng asked back: "Is it really not suitable for children?"

Meng Zhoushan paused, but didn't know how to answer. He covered the pen and simply put away the manuscript, feeling a little helpless: "Kiddo, the word unsuitable for children should not be used indiscriminately."

He walked to the coffee table and made himself a cup of coffee. When he passed by Sui Yuesheng, he saw that he was watching a horror movie in the past on the tablet. He leaned over and tapped twice on the screen to switch to a cartoon.

Sui Yuesheng raised his head to look at him, his soft hair brushed across Meng Zhoushan's chin, itching, his eyes puzzled: "Shúshu?"

The cologne on Meng Zhoushan's body was covered by the scent of tobacco, and his voice was deep and magnetic. Different from the gentle and handsome appearance, the concept is a bit old-fashioned: "Kids should watch cartoons."

Sui Yuesheng was about to say something, when he heard a muffled sound outside the window, as if something was hitting, he couldn't help but pause.

Meng Zhoushan also noticed that something was wrong, he frowned unconsciously, walked to the window and opened the curtain with a bang. The glass windows reflected the old building on the opposite side, and the whistling wind sounded outside, nothing unusual.

"Clack-"

The dull noise sounded again, which was keenly captured by Meng Zhoushan. He adjusted his glasses and looked up subconsciously, but saw a black shadow in the shape of silk threads appearing above the window at some point, fluttering gently in the wind.

Meng Zhoushan's intuition was telling that something is wrong, and he was about to stretch out his hand to open the window, but before he started to move, he saw a black line suddenly descending slowly, revealing a pair of frightened and widened eyes outside the window, followed by nose, mouth, and then The whole head-

It was a female corpse that was hung upside down outside the window.

A rope was tied around her ankle and she was hung outside. Her thin figure was like a weak weed in the night wind, swaying back and forth, and then hit heavily on the glass window of Meng Zhoushan's house, leaving a winding bloodstain.

"Clack-!"

"Clack-!"

"Clack-!"

Her body slammed against the glass window, her distorted and horrific face was moving away and approaching, making people tremble in the night. A red silk scarf was tied around her neck, tangled and fluttering, soaked in blood, dazzlingly red.

"Clack-!"

"Clack-!"

"Clack-!"

She banged against the window in the outer room, getting heavier and faster, making one wonder that the glass would shatter in the next second.

Meng Zhoushan took a step back subconsciously, his complexion changed slightly.

Sui Yuesheng also turned off the tablet. He quietly grabbed Meng Zhoushan's clothes and unconsciously leaned closer to the man.
