Chapter 24: Night Thief
Cui Jian encouraged him, "Today is a great opportunity. You stay in the infirmary overnight and I'll stay with you. The faculty office is upstairs. As long as we get the surveillance footage, we can find out the identity of the traitor, and we can get extra credits by voting on the weekend."

Yu Ming made up his mind: "Okay, give me a bite of steak."

Cui Jian said: "No, the school doctor said you can't eat greasy food for the time being."

Yu Ming was angry and said, "But you prepared a whole pot of meat and ate it in front of me?"

Cui Jian looked at the bedside table and said, "There are still two bowls of porridge. Have some."

After drinking the porridge, Yu Ming regained some energy, and the two of them spent time in the infirmary by browsing their phones and chatting. Every hour, the school doctor would come to check on Yu Ming. Cui Jian's main job as a bedside attendant was to change the IV, which was basically glucose with electrolytes and other things added in.

It was 10pm, and the bustling dormitory area had become very quiet. The school doctor checked Yu Ming's condition for the last time and wanted to let them go back to the dormitory to rest. So Yu Ming spit out a mouthful of water, and the school doctor asked Yu Ming to stay in the infirmary to rest, and asked Cui Jian to stay with him and call him immediately if there was any problem.

After tricking the school doctor away, Yu Ming and Cui Jian faced off. If it were yesterday, this wouldn't have been so troublesome, but tonight the security remained the same late at night, and even the police patrol car was not withdrawn.

Cui Jian closed the door of the infirmary and turned off the lights. Yu Ming changed the alarm on his cell phone to vibrate, and the two fell asleep on the bed and the bench.

At 2 a.m., Cui Yu and his team climbed out of the infirmary window and found the office area on the second floor. There was one office for each instructor and only one school affairs office.

Cui Jian grabbed the water pipe and tried to climb up. Yu Ming pulled Cui Jian down and handed him a large mask and a pair of medical gloves. Cui Jian was stunned. This wasn't murder, so why bother? Seeing Yu Ming nod, Cui Jian impatiently put on gloves and a mask, and then slid up to the second-floor window sill. This was an old building, and there was a one-meter platform outside the window sill. The purpose of the platform was to prevent objects from hitting people.

Yu Ming started to climb up, and his whole body ached. Fortunately, it was not very high. Cui Jian lay on the platform and reached out to grab Yu Ming's hand and pulled him up to the platform. Then Cui Jian heard the sound of the window latch on the third floor above, and immediately stood against the wall with Yu Ming. The next second, a flashlight shone down. Cui Jian was shocked. He thought that the process did not make much noise. The other party closed the window and drew the curtains. How did he notice that there was someone down there?

Who is this Li Ran? Above is Li Ran's dormitory.

The flashlight went out and the window closed again. Yu Ming took out a small wire and reached into the window, hooking and pulling to open the latch. The two of them gently opened the window from the left and right, entered the school office, and closed the window gently.

This is an open office with ten workstations. Yu Ming and Cui Jian stood on the left and right, holding their cell phone flashlights and began looking for the cameras that were confiscated by the school affairs department.

After searching for a while, Yu Ming rubbed his hands together and made a sound. Cui Jian bent over and walked quickly to Yu Ming's side. Yu Ming held a stack of test papers filled in with answers in red pen. Cui Jian looked at the questions: How many ways are there to access security cameras? How to avoid being hacked? How to protect the security of mobile phones?

Cui Jian typed on his phone: "Final exam paper?"

Yu Ming replied, "I don't know." Then he took his phone and crawled under the table. He and Cui Jian used their clothes to block the flash and took photos of each test paper with their phones. After finishing, Yu Ming put the things back and the two continued to work.

Not only is the building old, but the workstations are also old. It is a simple table with three drawers underneath, a small cabinet on the left, and three small drawers on the right. Glass is placed on the table to make the table look neater. The three medium-sized drawers can be locked with relatively old locks.

It is not difficult to unlock the lock, but the more annoying thing is that the lock makes a loud noise when opened, and some padlocks will bounce back directly.

Cui Jian and Yu Ming both used two paper clips to open the lock. Yu Ming's ability to open the lock was obviously better than Cui Jian's, which made Cui Jian very dissatisfied. After searching six workstations without any results, footsteps were heard from the direction of the stairs. The two immediately crawled under the table. The workstations of this type of table are connected under the table, but the computer host is placed on it, which is easy to make noise.

Ellie's voice came: "This is the list. The people on the list are weaklings. After class tomorrow afternoon, they will all be left behind to do muscle breathing training. The training location is the yoga room in the gym on the second floor of the cafeteria. There is drinking water in the yoga room. This is tranquilizer."

A man's voice came: "I don't like your arrangement. I like to go at my own pace and eliminate people according to my own preferences."

I have never heard this voice before, but I think it makes sense. There are more than 100 students and 10 school affairs. Cui Jian remembered the evaluation of himself by the housekeeper. The housekeeper thought that he was excellent in all aspects, with strong adaptability, calmness, and likes to think. He also has shortcomings. His mind will automatically reject people and things that he doesn't care about. In addition, Cui Jian felt that this person's voice should not be his original voice. There are many ways to change voices electronically. One is to fuzzy the sound, and the other is a pure electronic sound without life. Another way is to change the sound frequency, which can change male voice into female voice, and muddy voice into alto. The last one is easy to be mistaken for the real thing, and it is almost difficult to distinguish by ear. It is also the most unsafe because the speaker's voice can be restored through technical means.

Cui Jian basically determined that this person was a black card instructor. He believed that the black card instructor used the last method of voice changing.

Ellie said: "We need you to eliminate the weaklings, not the elites."

Black card instructor: "Can those who are eliminated still be called elites? Besides, it's not your turn to teach me how to do things."

Ellie chuckled: "Little brother, is your attitude because you are dissatisfied with the investigator named Yu Ming?"

Black Card Instructor: "He was supposed to be my prey this morning."

Ellie said: "He knows you are targeting him, so he is forced to reveal his trump card. We will not refuse an investigator to become a bodyguard."

Black Card Instructor: "He won't be a bodyguard."

Ellie: "Maybe. I'm different from Lin Chen. I like eccentric people the most. Let's put it this way. Except for him, you can do whatever you want with the others. I will keep the 10 people with the worst grades in the physical training class."

Black card instructor: "The 10 people with the worst grades, not the 10 people on your list."

Ellie: "I like people with personality like you... Don't hide, I just want to pinch your face."

"Go away!" the black card instructor asked, "Where's the key?"

Ellie handed over the key: "What are you going to do?"

Black card instructor: “I won’t tell you.” Then he opened the door of the school affairs office, returned the key to Ellie, and closed the door.

Ellie sighed for not pinching her cheeks, and turned to go back, but she saw another person at the stairs. Li Ran appeared there at some point, silently, with his chest held high, like a mountain.

Ellie was a little surprised and explained, "It's nothing. My friend has something to do in the school office."

Li Ran: "The sound came from your friend?"

Ellie exclaimed: "You are amazing."

Li Ran: “No big deal, good night.” He turned and went upstairs.

Ellie: "Goodnight."
