Mo Cong handed over all the things here to Yan Jia, he went to the principal's rest area now, and found that there was nothing here, just a few people's hair, this hair was still wet, so the weather was not so hot now, and who would suddenly cut off his hair and put it here.

Mo Cong had already seen the newspaper on the top of the newspaper It was quite strange, when the photo was pasted on it, the scene of the city leader reward that the principal had received not long ago.

He looked at the newspaper, it was really strange, Chinese characters and Arabic numbers were crossed with each other, who was on this newspaper?

Didn't they get the first draft approved?

Mo Cong quickly pressed the phone number above, "Hello sir, what do you need to help you with?" This is Art Times Publishing House. ”

I asked straight to the point: "Have you interviewed the principal of our school and some teachers and students recently?"

The other party listened to what Mo Cong said, and smiled even more, "Recently, we have interviewed all schools in the city, and the special medicinal powder they developed has been successfully published!"

The phone was hung up with a beep, and Mo Cong only heard the other party say before that: "Damn, it's time for him to know again." ”

The technical Xiao Wang has been gesturing to Mo Cong, and the location of the phone has been determined, that is, less than five hundred meters away from their library, a small publishing house that has just come out.

The boss inside used to be an old acquaintance with the principal, and Mo Cong quickly took someone there.

When they came here, the scene was the same as what they had just experienced, there was nothing left at the scene of the explosion, and the only thing left for them was the special medicine that would make people's bones disappear in an instant!

The instructions for that kind of medicine are no longer there, and it seems that the medicine has been very old, and the handwriting on it has been polished by the murderer very clearly.

Mo Cong said loudly angrily: "I must find out about them, they are the real murderers who killed my mother." ”

What everyone didn't notice was that there was a man in the corner, he was laughing, he was the principal's twin brother.

Today he just wants the principal to die, the principal has been injured by his real sleepiness, and he has always wanted to take away the results of the school's indoor laboratory as the principal.

Mo vaguely felt that there was something abnormal in the corner, and he quickly took Su Huan's hand, "Now take care of this medicine bottle, and remember that no matter who you are, don't easily hand it over to him." ”

Su Huan nodded, "Be careful where you go." ”

Mo Cong quickly came to the corner and saw a person's wig, and this wig was basically the same as what he had just discovered, so it was more certain that the murderer must be hiding in the dormitory in their school, or one of their teachers.

Returning to the serious crime team, Mo Cong told Yan Jia all his findings, "The other party thinks that what he is best at is playing explosion games, and the explosion switch is completely devoid of this powder." ”

The powder has been brought to the serious crime team by Mo Cong.

Yan Jia, when he looked at him, asked more softly: "Are there any suspicious people who are interested in following you or about you recently?"

Mo thought hard and looked at Yan Jia deeply, "By the way, just last Monday, there were two men, they admired my mother very much, and they also said that my mother was a particularly good experimenter. ”

Yan Jia responded to him helplessly... Ah, your mother's affairs aside, let's talk about what is so special about that laboratory at the school, have you seen all the previous experiments?"

Mo Cong shook his head, and so did Su Huan.

Su Huan continued the topic they had just discussed, "In addition to the art teacher, the research and development personnel of the laboratory have only recently appeared as music teachers, and we can't do anything about their real names." ”

Everyone was waiting for Qiu Yu's body to be reported.

When Qiu Yu woke up in Deyang Hospital, she thought that the murderer had taken advantage of their special attention, so he would act in front of them and replace the special medicine powder.

Qiu Yu quickly dialed Mo Cong's phone, "Now you must go to the principal's office, although it has been blown up, you must find a button." ”

"A button, does it have anything to do with this case?"

Qiu Yu repeatedly instructed them: "That button is one of the medicines they have been developing, and I believe that they must have divided the prescription into several parts and changed the ingredients." ”

Mo Cong quickly hung up the phone and took Su Huan back to the campus, and when they returned to their dormitory, they saw Jiang Rou with a sad face.

Jiang Rou saw Mo Cong and said quickly, "You don't know, right? I just received a call from a person who kept saying that he was our principal, and also told us that the secrets in the laboratory had been destroyed by him. ”

Headmaster?

Su Huan shook his head, "No, the principal's family said that the principal had already gone out on a trip two days ago, so why did he suddenly do all this?"

At noon, Mo had already arrived at the principal's house early, and it was the housekeeper who received them.

The Headmaster's wife wasn't there at all.

Mo Cong has always been here, and told the butler: "You don't have to come to take care of me, my principal just asked me to find a book here." ”

Mo Cong has been waiting for the murderer in the corner.

He had already contacted Yan Jia before, and always felt that the murderer had killed the principal. Impersonating the principal of the school.

Things are just as he guessed, the real murderer has put on a mask, and when he came back, he has been sneaking into the study, and he has been rummaging through a file bag, and he also said angrily: "I really don't know where to go, if you can't find it, it's over." ”

Mo Cong has been in the dark layer of the study.

There was a loud bang, which completely frightened Mo Cong.

Mo Cong had already found a large box in front of him, which contained all kinds of experimental equipment and potions.

He also heard the footsteps getting closer and closer to him, and he deduced that the other party must have come to find these things, so he quickly took off his coat and covered it, and quickly put the potions on top of his clothes.

He hid in the corner, and the footsteps stopped.

Mo Cong had already concluded that the other party was less than one meter away from his position, and sure enough, the other party had quickly turned the bookshelf over in the next second and saw Mo Cong appear.

He shouted like thunder... Ah, who the hell are you?"

Mo Cong shook his head, "The principal hasn't seen you for a long time." ”

As he spoke, he quickly walked out of the study, quickly put the table on the door, and ran in front of Yan Jia.

Yan Jia understood his intentions, and everyone quickly rushed outside the room, and when they picked the door lock, they had already seen that the fake headmaster was dead, and there were still Mo Cong's clothes on it.

When everyone saw this scene, they were even more disappointed.

Yan Jia sent Mo to ask softly, "Why did you kill him, is your mother's matter really that important?"

"When your mother died, there was no clue left. ”

Mo Cong's explanation was useless, those people saw the fake headmaster holding his coat, and he was holding a letter in his hand, which Mo Cong had written to his mother.

I hope that my mother, who is on the other side, can know how difficult it is at this time.

In this way, Mo Cong was taken away, and when they left the principal's house, they had already seen the principal's husband get out of the car and buy a lot of things in his hands.

"Mo Cong, why did you appear at my house, by the way, the housekeeper said that you have been in the master's study all along, what are you doing there sneaky?"

At this time, she had already seen the dead home covered with a white cloth, and wept bitterly, "Why did you leave me like this?"
