Chapter 22 Conspiracy
After hanging up the phone, Cui Jian saw Yu Ming coming out of the dormitory building, so he waved. Yu Ming wandered under a tree to avoid the sun, and handed a can of Coke to Cui Jian: "I just said why I didn't see you."

Cui Jian asked Yu Ming to sit down and told him his opinion on the female restroom incident. He said, "There is a loophole in my speculation. I assume that the black card instructor is a male student and no student leaves the classroom during class. That means the black card instructor has to go to the restroom to install surveillance cameras when class is over. The surveillance cameras are located on the ceiling and you need to step on the sink to reach them. After you come down, you have to deal with the sand on the sink."

Cui Jian: "From the moment he entered the women's restroom, I estimate that the whole process would take at least 20 seconds. As a male student, he didn't have much time to put on makeup, and at most he could put on a wig. How could he guarantee that no other girls would enter the restroom within 20 seconds and see him installing the camera?"

Yu Ming asked: "What if the people who installed the surveillance cameras were female students or female faculty members?"

Cui Jian shook his head: "No, all the information shows that the black card instructor should be a man."

Yu Ming said: "You forgot someone."

Cui Jian asked: "Who?"

Yu Ming replied: "A traitor."

Cui Jian suddenly realized why he had forgotten about this guy. The rules mentioned that there was a traitor in the academy, but they did not say that the traitor would do any harm to the students, which could link the traitor to the black card instructor.

Cui Jian asked: "Who could it be?"

Yu Ming shook his head: "The scope is too wide. The only girl who has met the black card instructor doesn't have much impression of him. But there is a way. As long as we get the surveillance, we can find out who installed the surveillance from the memory card."

Cui Jiandao: "There is another type of monitoring that does not require a memory card." You can watch real-time video.

Yu Ming said, "Cui Jian, you didn't seem to be paying attention in class today. When Instructor Li Ran introduced surveillance, he said that there are surveillance methods that don't require memory cards. One method uses the cloud. The other uses a mobile phone hotspot mode or a similar transceiver. The latter has a more obvious time lag. The longer it is left, the longer the lag will be."

Cui Jian said ashamedly, "I didn't pay attention." What Li Ran introduced in this class today was too homely, and Cui Jian didn't have much interest.

Yu Mingdao: "As long as I get the surveillance camera, if I'm lucky, I can find the phone that has been connected to the cloud through a friend who is familiar with computers, and find the videos stored in the cloud."

Cui Jian continued ashamedly: "I didn't think so much. You are indeed an independent investigator."

Yu Ming said: "Don't underestimate yourself. I can think of a lot, but that's because I have considered one more variable based on your opinion. If you had put 50% of your mind on the black card instructor and the traitor, you would have discovered the problem long ago. I'm not being modest, this is the truth. You are smarter than me, but you just don't focus enough."

Cui Jian nodded with satisfaction: "I agree with you that I am smarter than you."

"Haha." Yu Ming laughed and looked towards the second floor of the teaching building: "The surveillance camera was removed and taken away by the school staff, so it should be in the school office now."

Cui Jian paused: "You don't mean that?"

Yu Ming nodded and said, "That's what I mean."

Cui Jian: "In the evening?"

Yu Ming nodded again and asked, "Can you pick a lock? A cylinder lock."

Cui Jian said: "I don't believe you can't open it." This is almost the easiest lock to open. Its advantage is that it is easy to install and replace.

Yu Ming said: "It's a token of surrender."

Cui Jian smiled: "Okay, I wonder if the security guards and police stationed here will take care of this matter?"

Yu Ming replied: "Then avoid them."

Cui Jian agreed, and the two of them drank Coke and chatted under the tree, talking about their work in the evening, Hancheng, Yu Ming's boss and Cui Jian's Xifeng Mountain, and then they leaned back and rested under the tree for half an hour.

……

In the afternoon, it was practical class. At 2:20, all the students began to rush to the playground in front of the teaching building. There was a 300-meter plastic track in the playground, with two half-court basketball courts and one half-court football field.

Yu Ming asked as they walked, "Aren't you going to take a leave?" Cui Jian was puzzled: "No."

Yu Ming kindly said, “I can help you edit it.”

Cui Jian: “Why?”

Yu Ming glanced at Cui Jian and said, "Maybe not."

"what?"

A whistle sounded from the playground, and Lin Chen's voice came from the loudspeaker: "Line up, 12 people in a row, count the rows yourself, and run, don't be a sissy."

Cui Jian smiled: "We guessed correctly, Lin Chen is indeed the instructor."

Yu Ming looked at Cui Jian with a strange look in his eyes, nodded and said nothing. Cui Jian was puzzled. What was going on? When he joined the team and was in the last row, Cui Jian suddenly realized: "Oh no."

Cui Jian hadn't figured out how to deal with it yet, when he heard Lin Chen shout, "Cui Jian, come up, get in the first row."

Finished, Cui Jian trotted forward, Lin Chen pushed a girl in the first row to the back and made room for Cui Jian. The sun was not strong today, but Cui Jian had already started to sweat.

Lin Chen was wearing a gray training uniform, a training cap, a headset on his ear, and a loudspeaker on one side. She first asked for a count, and after counting, she counted with her fingers, but couldn't figure out if anyone was absent, so she said, "The first lesson of mixed martial arts: grappling. The key to grappling is strength. Especially for women, if your strength is too different from that of the opponent, grappling will turn into being captured. Explosive power is more important than strength, and there will be instructors who will teach you how to train explosive power in the future. Cui Jian, step out."

God!

Cui Jian took two steps forward, and Lin Chen said, "Today I will show you how to deal with three common situations. The first move is when I get close to the opponent, Cui Jian comes over and hugs me."

There was a chorus of boos from the audience, and Lin Chen walked down and said to a man, "You didn't follow the classroom rules. You will have to run ten laps after class."

The man protested: "A lot of people shouted."

Lin Chen: "Just catch one each time."

The man was speechless.

Lin Chen: "Cui Jian, come here and hug me. Hey, generally speaking, criminals won't hug bodyguards in an obscene manner."

Cui Jian let go of Lin Chen, not knowing what to do with his hands. Lin Chen had no choice but to reach out his hands, and the two grabbed each other's arms. Lin Chen said: "The bodyguard must first control the criminal's arms. When competing with each other, when the difference in strength is not big, both sides are helpless."

Lin Chen suddenly lay back and pulled Cui Jian, who stumbled forward. Lin Chen was a little surprised: "Very stable, but this also temporarily frees us from the entanglement with the criminals. Continue, come over."

The two men were close to each other, and Lin Chen punched Cui Jian, saying, "My fists can't be used at this time, and my elbows and knees can't cause any real damage to the opponent."

"Ah!" Cui Jian screamed, let go of Lin Chen, and squatted down to protect his balls.

Lin Chen wiped his sweat and said, "Sometimes good luck can cause damage." He reached out to pull Cui Jian up and got into position again.

Lin Chen knew that Cui Jian's lower body was stable, so he leaned forward and hooked his left foot on Cui Jian's heel. Cui Jian subconsciously stepped back, but was hooked by Lin Chen's left foot, so his body leaned back: "Pay attention to your hand movements." Lin Chen put his forearm horizontally in front of him.

The two fell to the ground together. Because Lin Chen controlled his hands, Cui Jian's back hit the ground with the weight of himself and Lin Chen, and he almost couldn't catch his breath.

Lin Chen lay motionless on Cui Jian and said, "Not only will your arm create a recoil for you, but it will also naturally strike the opponent's neck upwards with the impact. The key to this action is to combine the waist and the horse, and do it in one go. Use your own weight, plus the strength of your waist, to form a point of explosive power that will make the opponent lose balance. Okay, two people in a group, practice it, and after you are familiar with the movements, you will react naturally when you encounter this situation. Remember, countering a move is a myth, and practicing offense and defense into instinct is the right way, and let your body be faster than your brain."

"Instructor, can you demonstrate it again?"

Cui Jian was furious when he heard this: "Who? Who shouted? If you have the guts, stand up."
