The doctor said, "There are three things you must remember when you go in to work."

"First, you must never let this bottle leave your side. If you lose the bottle and something dangerous happens, you are responsible for the consequences."

"Second, don't talk to the patients, and don't believe anything they say. Apart from the doctors and nurses, there are no normal people here. You can't trust anything they say."

"And don't approach the patients on your own initiative. It's best to keep a certain distance from them. The patients here are all seriously mentally ill, and many of them have violent tendencies."

"They are not held legally responsible for hitting people! If anything happens, we're all in trouble."

"Third, don't go into rooms you're not supposed to, because they don't need cleaning."

The doctor emphasized, "Do you all understand?"

"Understood!" I deliberately waved the bottle. "What exactly is this stuff?"

The doctor said, "It's something like a sedative. It doesn't work on ordinary people, but it has a calming effect on mental patients."

"There are four buildings in total. You can choose to sweep from the outside in, or from the inside out!"

"If you can't finish cleaning before dark, go to the dormitory building to eat and sleep immediately. Don't go out at night. Continue cleaning when the bell rings tomorrow."

The doctor asked, "Have you remembered everything I said?"

I nodded. "I've remembered."

"Alright, go to work then!" The doctor turned to leave, took a few steps, and then suddenly stopped again. "Oh, there's something I have to tell you."

"You must clean the entire hospital within three days. If you exceed the time limit, the consequences will be very serious."

I looked at him and said, "Does the three days you mentioned include today?"

The doctor paused slightly, then stood there and hesitated for a while before saying, "No! The dormitory building is over there, you can go and rest on your own."

This time, the doctor seemed to be deliberately avoiding us, quickening his pace and disappearing without a trace.

I turned around and went to the dormitory building. As soon as I walked in the door, I saw an old man in blue clothes at the gatehouse, opening the window. He cautiously lowered his voice and said, "Are you here to clean?"

The old man spoke as if he were giving a password. If I hadn't practiced martial arts and had good hearing, I wouldn't have been able to hear what he was saying.

I also lowered my voice and said, "Yes! A doctor told me to stay in the dormitory first."

The old man took out a key. "Go right after you enter, walk to the end, room 107, that's where you'll be staying."

I took the key and said, "Men and women in the same room?"

The old man said, "There's only one room left, so you'll have to make do for a couple of days!"

"Don't talk loudly, whether you're in the room or in the corridor."

"The people in this building are not in a good mood. It won't be good if you wake them up."

I pointed to the door. "Sleeping in broad daylight?"

The old man lowered his voice and said, "Isn't it just sleeping in broad daylight? Don't talk loudly at night either. If they hear any noise, they'll come looking for you."

"Hurry up and go!"

As I walked down the corridor with the key, I glanced at the gatehouse out of the corner of my eye and saw the old man turning around at the window, facing me, shaking his head constantly.

It was as if he was regretting something.

After I entered room 107, I transmitted my voice and said, "Did you guys notice anything just now?"

Feng Ruoxing responded, "We didn't hear any breathing sounds in the rooms we passed. If there are people inside, it means they are all dead."

Wang Xiaohuan said, "Are we going to wait until night to make a move, or go out now?"

I pondered, "Let's split up. Before dark, no matter whether we find any clues or not, we'll all come back to meet here."

"Huanzi, you stay in the dormitory and wait for us. If we don't come back before dark, use a white light to guide us and bring us back."

I looked at Feng Ruoxing and said, "Did you see the inpatient building? Go and see if you can find Luan Jingfan's admission records in the inpatient records room."

"Remember, whether you find it or not, you must retreat as soon as possible."

I then said to Ye Yang, "Leng Gou, when I came in, I saw that the roads in the hospital were a bit strange. Maybe there won't be any roads here at night. You're good at feng shui. Go and create a road, so that we don't win the battle and then can't retreat."

Ye Yang nodded and asked two words, "What about you?"

I replied, "I'm going to the president's office to see if there are any clues there."

"If I'm not mistaken, this should be a stronghold of one of the Four Direction Famous Arresters. Let me see what's in the president's office."

I was about to go out when I stopped again. "Everyone, be careful. If anyone accidentally triggers a restriction and is surrounded by ghosts and monsters, choose to break out immediately and retreat first."

"Don't try to rescue anyone else, so that you don't all get trapped here."

"According to our cultivation, as long as the other side doesn't have more than two Sifang Guishen (Four Direction Ghost Gods), we can hold on for a while. There's still time to rush out and call for reinforcements."
