... when there were only the last few steps left on this staircase, Lin Sanjiu raised his head.

As she expected, a three person sofa occupying most of the corridor and a brownish red panda appeared in front of her again.

Lin Sanjiu sighed softly.

She just started from here and walked up. As a result, after climbing three floors, she really returned to the origin.

It seems that you can't get out of these three stairs by ordinary means.

"Don't say it. It's really like ghosts beating the wall." Lin Sanjiu leaned down with his wings and didn't go anymore: "... I used to read ghost stories, as if I said that boy urine could break ghosts hitting the wall."

With that, she turned her eyes to the panda.

"Don't look at me when you say boy," Qing Jiuliu bared his teeth at her: "don't insult people."

"... it shouldn't be that way," the blue rag sofa interjected. "I think we've been attacked by others."

"Is it the old woman? We didn't provoke her. Why did we just stare at us..."

Lin Sanjiu looked at them and thought of a way - she stood up and walked to the door marked "exit", opened the door with her huge body, turned her head and said, "you follow behind, I'll think of a way from the floor... It's really not possible, so I jumped out of the window to see if I can break this strange circle."

Hearing this, the little panda immediately jumped onto the sofa and squeezed into the door with the strength of Ji Shanqing moving forward a little bit with her teeth clenched.

... the 16th floor looks nothing different.

The carpet was soaked with blood and dried in the shade over time, making it crunchy. The corridor was filled with a long suppressed iron smell and musty smell, which was more unbearable than the top floor - the price of rooms on the 19th floor and above was too high, and they were empty before the end of the day, and they were well preserved; Unlike the 16th floor, the doors of several guest rooms are still half open, because they are blocked by the dead bodies of the tenants at the door.

It's said to be a dead body, but in fact, I can't see any human shape for a long time.

It seems to have been bitten and cut after death, and most of the white skeleton of the potholed body is exposed; The skeleton was hung with dried dry black flesh. Together with the rags, it was shaken by the footsteps of Lin Sanjiu passing by.

"It's similar to what I saw last time." after quickly checking the corridor, Lin Sanjiu "pedaled" back quickly and said to the other two people, "wait for me here, and I'll try climbing up the balcony."

With that, she pushed open a door beside her - the huge chicken wings were like a broom, swept out the broken corpses on the ground, and walked into the house.

The guest rooms on this side are equipped with a delicate small balcony; Although it was difficult to climb without both hands, if he flapped his wings and jumped up hard, Lin Sanjiu's beak could also reach the edge of the balcony upstairs - followed the two people in the room, watched the two big chicken claws pedal hard in the air for a few times, and finally climbed up and disappeared out of the window.

There was a moment of silence in the room.

"What do you think?" After a while, the brown red panda suddenly spoke.

"... not very promising." The blue sofa sighed and said.

"What if we go down?"

"If we go downstairs now, we should return to the 18th floor."

Qing Jiuliu was stunned and turned half his body to look at the sofa behind him: "have you -"

"Look," Ji Shanqing suddenly interrupted him, "out of the window."

As if to confirm his words, something came up on the edge of the small balcony outside the window; With the support of its wings, a familiar beak also caught the iron railing - gradually, the old hen incarnated by Lin Sanjiu flapped vigorously and popped her head from under the balcony. As soon as her dark round eyes were aligned with the two people in the room, a series of "grunts" sounded in her throat, probably swearing.

"... damn it!"

After she managed to stabilize her body, the first sentence was this.

"What's the matter with these three floors? Why can't you get out!" As a messy old hen came into the room, small feathers were flying in the air: "... Why don't I jump downstairs and try? I can still see the ground -"

"Don't you," Ji Shanqing hurriedly said, "I guess if you jump from the 16th floor, you will fall from the 18th floor... And then keep falling between the three floors of 16, 17 and 18, and never stop."

Lin Sanjiu raised his head and looked at the sofa in front of him. She didn't know where Ji Shanqing's "face" was. She could only turn her eyes suspiciously: "... Do you guess what happened?"

"Well, I came up with an answer - in fact, it's not difficult to guess." Probably seeing Lin Sanjiu's eyes brightened, and Ji Shanqing's voice also brought a little shyness: "although I don't know whose ability this is - or a special item - but the distance from the 16th floor to the 18th floor has probably become a mobius ring now."

This word sounded so familiar that Lin Sanjiu frowned. Just when she recalled where she had heard this word, Qing Jiuliu had responded with an "ah" voice: "that tape with head to tail connection and infinite circulation!"

"Yes, if you stand on the surface of Mobius' ring and walk, you can go round and round without end..." Ji Shanqing said thoughtfully, "isn't it very similar to our current situation?"

"I vaguely remember this thing, as if it had something to do with mathematics." Lin Sanjiu replied, "knowing this, what should we do next?"

The question was very constructive, but no one answered her.

She was about to ask again when she suddenly found that the panda raised her head - the other party's bright black eyes slowly moved to the sky and stared at her back. Qingjiuliu also quieted down, just like a real sofa.

There is something behind me!

Lin Sanjiu suddenly turned around, and his eyes fell on that thing, immediately surprised.

Above the balcony, a head of black hair is hanging in midair; Just when Lin Sanjiu saw it, his black hair suddenly shrank upward and completely disappeared upstairs - it seemed that someone was hanging upside down and looking into the room just now.

"Wait for me here --!"

Before the two people behind him spoke, the old hen rushed out with an arrow step; The wings vibrated in the air, and she had caught the iron railing upstairs skillfully, pulled the chicken up, and quickly disappeared.

Qing Jiuliu sat up straight and stared at the balcony closely - but he was staring not at his head, but at the bottom of the balcony.

If that head of black hair escapes all the way up, it will soon appear under this layer.

After waiting for a few minutes, the edge of the balcony was still painted off white, and the dark top of the head that I imagined never appeared; And Lin Sanjiu didn't know where he was traced.

At this time, Ji Shanqing behind him spoke.

"Qing, Qing long stay?" His voice suddenly fell down and trembled a little.

This guy is smart, but he is a little timid... Qing Jiuliu crossed the idea in his mind and asked without looking back, "what are you doing?"

Although there was no saliva or esophagus, the blue rag sofa still made a clear "gulp" sound of swallowing saliva.

"Just now... Someone touched my backrest."

The little panda immediately twisted his neck, and the hair on his back had suddenly started.

... the back of the sofa is empty, and there is no one. As the sofa was parked sideways at the entrance, there was only a large open room door and a small stained corridor exposed at the door, except for a wall.

"What do you mean by touching...?" Qing Jiuliu lowered his voice and asked.

"I can't see behind me, but it feels like someone accidentally rubbed me when passing by." Ji Shanqing's voice was too light to be heard. "Anyway, I was hit by something."

Is it the owner with black hair?

The little panda grabbed the back of the sofa with his front paws, stood up with his two hind legs, and carefully poked out his eyes.

He turned his black eyes from left to right. Luggage table, carpet, light switch, door, and the pile of broken bones under the door

It seems that there is no difference from before, and there is no "person" as Ji Shanqing said.

wait a minute.

(it is said that you can't see the author's speech, so I'll write it at the end of the article. I'm back, and tomorrow's start day is on. Thank you for not abandoning me during this period of time, and I'm looking for a feeling. Please forgive me!)
