Mo Cong quickly returned to school, and he already saw Su Huan waiting for him.

Su Huan told him with a serious face: "Mo Cong, you don't know that there have been more and more strange things in the school recently, taking advantage of the students' vacation, several people in charge of the school actually destroyed all the items in the laboratory in the school history room on the spot. ”

Mo Cong's face was surprised when he heard this, it stands to reason that they should have quietly destroyed those items, what does it mean to destroy them in a bright way?

Su Huan was holding a bag, which contained a little evidence that he had managed to find, and these items had not yet been destroyed by the music teacher and the others.

They have not continued to appear in the students' classrooms, and in the face of all kinds of doubts, Mo Cong shook his head and said to Su Huan, Jiang Rou and the others: "Now that we are divided into three ways, you have to quickly investigate the matter of the music teacher, and I will continue to talk to the principal." ”

Mo Cong had just left, and Su Huan had already found that there was an extra letter in his bag, and the signature on it was even more strange, a person named Luo Nuannuan appeared, not to mention that there was something to find Mo Cong.

It's about Mo Cong's mother.

Su Huan quickly arrived at the door of the principal's office and saw Mo Cong's eyes wide, and his body couldn't move at all.

The door of the principal's office was open, and his belongings flashed on the sofa, and in the face of such a scene, Su Huan stopped his steps.

It has been found that a corpse has appeared behind the table, this person is Jiahui, he opened his mouth wide in surprise, and he kept shouting quickly Mo Cong, "You come in, the music teacher is dead, she has wounds all over her body, and there are some potions all around." ”

Su Huan immediately and quickly blocked the scene and called the police as soon as possible.

When Yan Jia arrived here, they were quite surprised, and now Qiu Yu has been transferred to other teams to help.

Yan Jia looked at Mo Cong with a bitter face, "What's wrong with you, we're here for so much, don't you even want to say a word to us?"

Mo Cong was gently pushed and fell straight over, and at this time, everyone saw the principal appear at the door.

Su Huan asked even more suspiciously: "Principal, have you been talking to Mo Cong about things just now?"

The headmaster nodded, "yes, I just told him to wait for me here." ”

Seeing the corpse appear behind his desk, he was so frightened that he immediately leaned against the wall and looked at Su Huan in front of him, "What's the matter with him, you, you killed her?"

Su Huan reacted quickly, "I didn't kill it, I came here to find the principal, but I didn't expect that the body of the music teacher had been found here." ”

Yan quickly said to them: "Now please go out, we will investigate this place immediately." ”

His own investigation found that Mo Cong's current situation was very special, and after the preliminary examination of the school doctor, Mo Cong just drank a glass of water containing sleeping pills.

So who had to kill this Jiahui in front of Mo Cong?

A small piece of paper in Jiahui's hand caught Su Huan's attention, and he quickly handed over the things.

Yan repeatedly instructed them: "Now that the entire school is closed again, to prevent the murderer from escaping, we will send someone to guard here twenty-four hours a day." ”

The principal nodded immediately, and his panicked expression was quickly hidden, but in the end, it was seen by Qiu Yu, who had just arrived.

Qiu Yu quickly asked, "What's going on here?"

Jiang Rou shook her head, she responded very nervously: "The music teacher died, and she took the initiative to call me before that, saying that she had a medicinal ingredient to hand over to Mo Cong!"

"Oh. Qiu Yu's puzzled eyes kept looking at Mo Cong who had fainted, and with the help of everyone, Mo Cong woke up again, widened his eyes, and asked seriously: "What's wrong with me?"

Qiu Yuwu gave him countless blank eyes, "What's the matter, of course it's your old mistake, do you remember anything special now?"

That's right, Mo came to the office from the moment he received the principal's call, the principal was not in it at the time, and he saw the principal appear at this time.

Mo Cong stood up immediately, he patted the dust on his body, and pointed to the principal's position with both hands, "Principal, you, what are you doing?"

Everyone looked at Mo Cong with a confused face, is there something wrong with the principal?

When everyone was suspicious, Qiu Yu saw the watch in the principal's hand, which had two drops of blood on it, and was about to ask the principal for the watch, the principal laughed.

"You fools, you're here waiting for death. ”

He quickly jumped from the second-floor window, ready to follow the rope safely to the ground, and lit an explosion switch.

When the switch sounded, Mo Cong and the others quickly hid in the music classroom opposite.

The good principal's office is now bombed beyond recognition.

Mo Cong shouted loudly: "Yes, that murderer deceived us by pretending to be the principal, and now he must have escaped." ”

When they chased out, they really saw the murderer driving the principal's car out of the campus.

They've surrounded it, so what kind of person let him go?

Qiu Yu quickly investigated the photos of the principal's previous life, they always thought that the principal would organize all the school's affairs here, but a small child appeared, and he cried very loudly: "Uncle and aunt, please help my father with good treatment, okay?"

The crowd followed him to another room, where the head of the school was resting and saw the real headmaster lying on the bed, panting.

Mo Cong quickly gave him a series of first aid measures, and the principal's weak voice told Mo Cong: "The secret you want is under my bed, and, and he didn't finish it." ”

Mo Cong wanted to take the initiative to touch the mysterious box, his hands had already been grabbed by Qiu Yu, "Don't act rashly now, the murderer may use the principal to make us face death again." ”

That's right, when Mo Cong opened the box, there were several switches of different colors inside.

When everyone saw this scene, they really didn't know what to do, the murderer turned his back to them when he pressed the switch before, and no one could easily press the switch right.

Mo Cong looked carefully, he always remembered that the principal liked to wear yellow clothes, on the contrary, he did not have a dark yellow switch, and judging from the corpse at the scene, the music teacher liked to wear white the most, so it was also ruled out, so only blue and pink were left, Mo Cong quickly pressed the blue switch.

Suddenly, all the blast systems were destroyed, and they were safe here.

Mo Cong took out a thick cardboard box from the box, all about a medicine developed by her mother back then, which could seal human memory, and a small bottle, the ingredients of which were gradually melting.

He asked the technical king to get it to be tested.

At this time, Qiu Yu's hand began to ache, and she said loudly: "Mo Cong, can you help me wipe off the kind of medicinal powder on my hand?"

Everyone has already noticed that Mo Cong has accidentally dropped this medicinal powder from Qiu Yu's hand just now.

He said guiltily, "I'm sorry. ”

was going to take Qiu Yu away, but 120 had already come, and the doctor said to them with a serious face: "If you don't understand anything, you have to touch this medicine, if you don't do it well, it will directly make you die." ”
