Tick tock......

The man's groggy head felt a drop of water, dripping down, and when he opened his heavy eyelids, the man felt a burst of weakness all over his body, and his body was a little paralyzed!

He remembers that before he fell unconscious, he went to the underground parking lot to drive home, but suddenly felt a figure behind him, and when he reacted, he could only smell the smell of ethanol!

Looking at the unfamiliar environment around him, the man found that he was naked at this time, with a chain tied to his feet, and the chain was tied to the table, and his body was coated with a layer of mucus, the man sniffed it, and couldn't help but constrict his pupils, he had the smell of phosphorus powder and gasoline, flammable and explosive!

It was a closed room, the man was lying naked in a corner, and beside him there was a small table, the table was made of iron, and there were candles and a pen and a notebook on the table, and out of the range of this table, the floor of the room was covered with all kinds of glass slag, and the walls were covered with all kinds of chemical symbols, and there was a square piece of glass on the wall!

The man quickly checked his body, except for his body being a little paralyzed, his body was not harmed, and he couldn't help but breathe a sigh of relief, but he was very puzzled, what was this person tying her here for......

Soon, the man noticed a brand new wall clock on the wall, apparently artificially placed on it, and the time on it was 5:15, and next to the wall clock walked a camera facing him!

"Click......

The square glass on the wall suddenly lit up, and on the opposite side of the glass, a man wearing a clown mask looked at the man with a slight smile, he was dressed in black, and his body was slightly rickety!

"Yes, good physical fitness!"

A slightly hoarse voice came from the other side, which made the man startled, and then he kept roaring: "Let me out, do you know who I am?" You're breaking the law......"

"Zizi ......"

The sound of electricity sounded throughout the room, and then the man couldn't help but collapse to the ground, his whole body was convulsing, and his whole body was red......

"Shhhh The man on the other end of the glass made a silent gesture with his fingers, and then shook his head slightly!

The man on the ground was stunned instantly, the pain in his body made him convulse constantly, he collapsed on the ground, looked at the man on the other side of the glass with a frightened face, and didn't dare to speak again!

"That's right......" The masked man was satisfied, then found a stool and sat down, "Shall we play a game?" If you win, I'll let you go, and if you lose, you'll have to die, okay? ”

"I ......" the man on the ground didn't know how to answer.

"Well, then you say yes!" The masked man nodded in satisfaction, and then said, "I'll explain the rules of the game." ”

The masked man pointed to the surrounding walls and table, "There's a safe inside the table, and the safe has a key that you can take to open the door and go out!"

There are all kinds of chemical symbols on the wall, and you just have to put them together, and then add them up according to the corresponding number of periods on the periodic table, you can open this safe, get the key, and you can leave, for a teacher, it's very simple! ”

Hearing this, the man on the ground turned pale, and then couldn't help but be frightened: "I know who you are, please...... Please let me go, I don't want to, it's none of my business! ”

The masked man shook his head: "No, I'm not the person you think, and it's been so long, it doesn't matter who is right and who is wrong, now I just want to play a game with you, if you win the game, you can go out, if you lose, you go down to accompany her!" ”

Hearing this, the man was even more frightened, he kept pulling the chains on his feet, and then kept screaming madly: "Let me go, let me go......"

The man in the mask was on the other side of the glass, just looking at him quietly, expressionless, couldn't help but shake his head, and then pointed to the wall clock on the wall and said: "It's half past five, you have forty minutes to uncover this problem, don't waste time!" ”

"Smack!" Then the light on the other side of the glass was turned off, and only the man was left in the entire confined space!

"Brute, brute, why did you do this to me!" The man couldn't stop roaring, his face revealing various expressions of hideousness, unwillingness, regret, and despair!

Two minutes later, the man was tired, his voice became hoarse, and he was the only one in the room, and then he began to use his pen to record the various symbols on the surrounding walls!

Time passed quickly, and the man on the floor wrote down all the chemical symbols on the wall in his notebook, but he found that there were still many chemical symbols that he couldn't see, which meant that he had to walk through the glass-filled room to find the answer, but he was barefoot......

After a moment of silence, the man on the ground gritted his teeth, he dragged the chains with his feet, and kept moving forward slowly, until he entered the edge of the glass slag, he took a breath and walked directly barefoot, and then a heart-piercing pain spread throughout his body!

The room was eerily quiet, save for the constant sobbing of men, the sound of dripping water, and the sound of the alarm clock gradually approaching the end!

Time gradually passed, and the room was already full of blood stains, covering every corner of the room, and the man behind the glass also turned off the computer when he saw this scene, and then stood up and took a deep breath: "The opportunity is given to you, see if you grasp it, good luck!" ”

In S University!

After solving the previous case, Zhang Yang returned to his original life, he originally helped the police solve the case when he was free, and his normal life is still on the university campus!

Zhang Yang talked about psychology and dream analysis in class, and there was a girl in red in the audience who was particularly conspicuous, she was sleeping on the table at this time, and Zhang Yang obviously saw this scene!

The students in the university are all adults, so the teacher only guides the students, and they are not as serious as they used to be, and it is normal to sleep in class, when Zhang Yang passed by her, he smelled the smell of ethanol, and couldn't help but shake his head, the current students......

And a phone call also broke Zhang Yang's peaceful life, a call from the Jiangzhou Police Department!

"Hello?"

"Zhang Yang, another serial case has happened, and I need your help! Also, Xu Shijie was forensically identified as having a high degree of schizophrenia, was exempted from criminal punishment, and is now arranged in the military hospital, he wants to see you! ”
