The two cleaners spoke vigorously on the stairs.

The fat man became more and more proud as he spoke, and he just threw his neck up and laughed.

The thin man did not feel bold after hearing the fat man's story, but felt even more scared.

"I said Fatty, your horrible childhood experience is something you can't escape, but now, we don't need to follow this weird trace to find ourselves uncomfortable, right?"

"Skinny, you coward, with me supporting you, can't you be bolder?"

"Fat man, as the saying goes, curiosity killed the cat. You don't have to be so curious."

"Skinny, you say that people live a lifetime. If you haven't eaten it, you should taste it. If you haven't seen it, you should go see it. You said you are in your 50s. You have seen the person who jumped upstairs on one leg. Did you specify that you haven't seen it. Since we haven't seen it, let's go up and have a look together."

"Fat man, I have a hunch that I will be killed by you sooner or later. You are the only one who die fast."

"Crap! My mother was buried alive at the age of seven. Tell me, I was buried alive at the age of seven, then I am not born a blessing and fate?"

"Huh, in my opinion, you are reckless and stupid, nothing else."

The two cleaners walked up babblingly, without stopping under their feet, and the weird babble did not stop.

"Have you heard? He is still climbing up on one leg. We only need to go up again to see him."

The thin man looked up and he was furry again.

"Fatty, who is up there?"

The fat man looked up and found that there was no one on the stairs, but the bang continued.

"Huh? Is it possible that the one-legged guy is an invisible person?"

"Fatty, please, don't chase anymore. My instinct tells me that it's not human at all."

Fatty's stamina came up, "No! Even if it is an invisible person, I will find him out."

"Fat man, you are really crazy."

"Skinny, you said that when we go to work every day, all we do is simple scrubbing and washing, which is really boring. Why not have some fun and pass the boring time?"

"I think you are so boring that I thought of killing time like this."

At this moment, the banging sound continued, and the sound felt very close, as if it was just above the head. There are still traces of that strange line of blood and white pulp on the stairs.

The fat man squatted down, staring at the weird traces on the ground, dipped his hand in the white pulp again, and nodded, "Well, it's still warm as before."

The thin man watched the acid water in his stomach, "Hey, fat man, stop doing those disgusting things on the floor. I'm going to throw up."

"You are really useless. You vomited? I thought that when I was seven years old, I had a rotten corpse lying in the same coffin. The pus and blood from the corpse at that time covered the brocade under the coffin. I was dyed red, and I was lying next to him, and I didn’t vomit. I was only seven years old then."

"That's because you are young and don't know how to be afraid."

"Bullshit, no matter how young I was, I was so afraid of being a career. I was so scared that I was peeing on my pants and thought I was dead. Unexpectedly, my parents came to dig the grave and saved me."

"Okay, don't mention your glorious deeds. Let's cast a mop now."

When the thin man finished speaking, he turned to leave, but was grabbed by the fat man.

"Don't go, I haven't said to go yet."

"I don't care about you, I have to go, urgency. And the food in the cafeteria today is not fresh, my stomach rumbling after eating, I'm afraid it's a stomachache."

The thin man clutched his stomach with an expression of urgency.

"No, even diarrhea, you have to hold back for me."

"Fatty, you are getting more and more domineering."

"Skinny, you really don't have the heart to search for the truth. You heard that weird bang statement that you are very close to us. I believe we will soon catch up with the one-legged guy. I'm carrying my phone, etc. I have to take photos of that stuff and send it to my circle of friends. I will definitely get a lot of likes."

"I really convinced you, you are quite fashionable."

"Isn’t it the current life fashion to post pictures when you’re fine and post them in your circle of friends?"

"That's the work of idlers, and it's part of the leisurely life of Mrs. Kuo. Those of us poor people who are busy making a living every day, what can we do? Besides, you bring your mobile phone to work, and be aware of being discovered by the nurses. Say it."

"What are you afraid of? My phone has been muted a long time ago, and no one can hear it even if the call comes."

"Just because you have a lot of ghost ideas, so every time we talk, it's because of you."

"Skinny, aren't you planning on breaking up with me?"

"That won't be true. We are good sisters, working partners, with you as a company, I will work much more safely."

"Then now, you just listen to me obediently. Let's keep going up and see what's on it?"

"Fat man, this staircase is just such a small place. As soon as you look up, you can see clearly. There is nothing, so what can we do if we climb up again?"

"Skinny, we are on this section of the stairs. Naturally, we can't see the one-legged person. Let's keep going up. Once we turn, we should be able to see him."

The thin man was dubious, "Huh? You mean, the one-legged guy is on the turn of the stairs?"

The fat man nodded, "Yes, you finally got the hang of it. What are you hesitating about, let's keep going up."

The thin man sighed and followed the fat man with his stomach.

Although the lights are on in the corridor, the light emitted is very weak because the lights in the corridor take a long time.

The fat man stomped his foot vigorously, but the light still didn't turn on.

"It's really stingy. The lights in this corridor are all of this virtue. This hospital is still reluctant to change it. It will be used as it is."

"Fat man, don’t you need money to change the lights? You didn’t see that this hospital’s operating conditions are not good, and personnel expenses are reduced. These doctors and nurses work overtime all day because of insufficient manpower. But if you recruit new people, you will have to pay more. So the doctors and nurses are all a carrot against two pits."

"Hmph, it's no wonder these doctors and nurses are so temperamental, it turns out that they also have grievances."

The two cleaners were talking, and they had reached the corner of the stairs.

Unexpectedly, the light on the corner of the stairs is darker.

The fat man stomped the voice-activated light, but he waited but it didn't turn on.

The thin man smiled, "Don't stamp your feet, this lamp is already flat, don't you know?"

The fat man sighed, "I forgot."

At this time, I heard the strange sound of bangs from the dimly lit stairs.

"Ah! I see, that thing is on this section of stairs without lights."

There is no light on this section of the stairs, and only the small section near the window is bright.

In the darkness, the humming sound continued.
