I turned my head to look at the blue and white building, which added up to five floors, and it shouldn't be too difficult to find.

"Let's go."

I didn't say anything more, and walked out first.

When I turned the corner, I happened to bump into Mr. Liu, and a stack of documents in his arms flew all over the sky in an instant.

"Oops! I'm sorry, teacher."

Xiaomei immediately squatted down to sort out the scattered documents, and apologized again and again.

Teacher Liu brushed the few hairs on his head and wiped the sweat from his forehead.

After the documents were sorted out, they exchanged a few polite words before leaving.

I looked at his back, then at the corner, and vaguely felt that something was wrong.

"Go, what are you looking at?"

Xiaomei urged, raised her legs to leave, and was called back by me: "Your shoelaces are open."

"Huh?"

Xiaomei looked up at me, her face full of suspicion: "I didn't open ......."

I squeezed my eyebrows vigorously, and Xiaomei immediately reacted and stepped on the documents left on the ground.

As she crouched down, I had retreated to where she had just been bumped in.

The corner of the wall is not a right angle, but an arc, and strictly speaking, there is no blind spot.

Also, no one was going to walk against the wall, and we couldn't have stumbled together in any case.

Teacher Liu's appearance is more like a premeditated tracking.

Of course, this is also expected by me.

What puzzles me is that he can be tracked in the dark, why should he take the initiative to show up?

I strode over to Mei and whispered, "What is written on this document?"

"Nothing."

Xiaomei handed the paper to me, and when I looked closer, it was completely scribbled, with missing corners.

Obviously, this is just a piece of waste paper.

I remember very clearly that the waste paper that Mr. Liu was holding in his arms was very neat.

In this way, it is even more unreasonable.

Although Mr. Liu's strange behavior cannot be explained for the time being, one thing is basically certain - he is by my side all the time.

Of course I can't let you monitor me, otherwise what else will I do to fight you?

But now Chen Changming didn't find out about my existence, which is undoubtedly an advantage for me.

I'm not afraid to flip the table and get started, but I don't want to waste my advantage.

I walked side by side with Xiaomei, and I asked in a low voice, "Is there any way to fall into a coma without seeing the trauma?"

"Yes, ether."

"Can you get it?"

Xiaomei shook her head slowly, her face showing a little embarrassment: "This is a controlled drug, there are no formal procedures, no one wants to get it."

"Moreover, once the dose is not well controlled, it is easy to cause temporary amnesia."

"Great, that's what I want."

Although her face was full of doubts, she still led the way ahead and did not stop until she was on the second floor of the teaching building.

"All the medicine is here."

I looked up and saw three big words written above my head: Storage Room.

I pulled the paper clip I used last time out of my pocket and asked as I checked the keyhole.

"How many exits are there on this level?"

"Just a staircase."

By this point, I had inserted the paper clip in: "You're walking near the staircase, and someone is coming, and you stomp your feet, but don't shout."

With the experience of the previous times, this time the unlocking is obviously much faster, plus the door lock of the storage room is relatively simple, only three or two minutes, the door lock has been opened.

Although I don't know medicine, I do know how to read.

The ether was stored in glass bottles, and I took a few out of my hand and a few rolls of gauze from the side.

Just as he was about to go out, he heard a shout outside the door.

"Ah, what a coincidence, Mr. Liu."

Xiaomei's voice was exceptionally loud, obviously speaking to me.

I couldn't help but pout and smile and sprinkle half a bottle of ether on the gauze.

I knew that this thing was evaporating quickly, so I quickened my pace.

When I came out, I happened to see Teacher Liu and Xiaomei chatting at the end of the corridor.

I put my hands behind my back and greeted with a smile, "Teacher Liu is here too!"

"yes, I ......."

By this time, I had already walked up to him, and before he could finish his next words, the gauze with ether had already been pressed on.

Almost in the blink of an eye, he went limp, and fell to the ground with a pop.

Xiaomei looked at me, then at Teacher Liu, and said in horror, "This ......."

"Follow me."

As I spoke, I had already dragged Mr. Liu into the storage room.

As I untied his clothes, I commanded, "Bring me all the valuable medicines in the house, the more expensive the better."
