"Damn, where!" After the four of them ran to the door of the teaching building as fast as they could, Zheng Hanfei discovered a problem, and they didn't know where the screams came from.

"Let's look at every floor!" Zhongli Wan'er suggested, "It's not a way to wait here. ”

"Good!" Zheng Hanfei thought about it, and now there is only this way, so he nodded and glanced at Gu Jie and Nan Ruoxun, the meaning is self-evident.

"Wan'er, are you there?" Ouyang Xiu's voice suddenly sounded around the four of them, causing them to stop and look around suspiciously, just as they wanted to run into the floor.

At this time, Zhongli Wan'er remembered something, and hurriedly took out a badge from her pocket, the badge was round and bronze, and a large pipe was painted on the surface, and below the big pipe, there were four black letters "icpo".

"Ahh President, I'm here, what's going on there! Zhongli Wan'er shouted at the badge.

"It's not clear here." Ouyang Xiu's voice came from the badge, "You first took Zheng Han to the sixth floor of the teaching building, and there was a case...... Yes! Before he finished speaking, the woman's scream came out of the badge, startling everyone, and Zheng Hanfei's face was a little gloomy, it seemed that what he least wanted to happen still happened.

"President, what's wrong?" Zhongli Wan'er shouted in a panic.

"Damn! Anyway, you should go to the chemistry lab on the sixth floor first, there is a case! Ouyang Xiu hurriedly said a few words and hung up.

"Let's go! Let's go to the sixth floor first! After speaking, Zheng Hanfei quickly ran into the teaching, and at the moment when Ouyang Xiu hung up, Zheng Hanfei heard a burst of footsteps, which showed that the case Ouyang Xiu said was not as simple as he imagined......

"This ...... What's going on? When the four of them ran to the door of the chemistry laboratory, they were stunned by what they saw. A man who appeared to be about thirty years old was hung in the center of the house, with a hideous expression, dilated pupils, endless fear in his eyes, his mouth slightly open, and at the feet of the deceased, there were some cardboard boxes that had been kicked over.

"Dead?" Zheng Hanfei looked at the scene with some solemnity, and asked Zhongli Wan'er behind him, "Did you call the police?" ”

"Yes!" Zhongli Wan'er closed her phone and nodded, "It seems that the president has already called the police before." ”

It is worthy of Ouyang Xiu! Zheng Hanfei praised in his heart, and at the same time felt a little puzzled about Ouyang Xiu's escape, what happened to make Ouyang Xiu temporarily ignore this murder?

"You ...... What are you doing here? The sudden voice interrupted Zheng Hanfei's thinking, and when he heard the sound, he saw a female teacher in her twenties and thirties walking towards them slowly, with a hint of disgust in her eyes, "I don't know if you can't enter the sixth or seventh floor casually!" ”

"Teacher...... Over here...... It happened...... Homicide case. Nan Ruoxun pointed to the chemistry laboratory with a trembling voice and said hesitantly.

"What?!" The female teacher's face was a little disbelieving, but she hurried to them quickly, and then looked at the chemistry laboratory, her pupils shrank, and she exclaimed, "Ah Liang! ”

"Teacher, don't go in!" Zheng Hanfei stretched out his hand in time to block the female teacher's urge to go in, "Before the police come, you can't destroy the scene!" ”

"Don't stop me! Let me in! How could he die! The female teacher didn't seem to listen to the persuasion and wanted to enter the scene.

"Teacher!" Zhongli Wan'er took out her badge again, put it in front of the female teacher's eyes and said, "Please calm down, if you still want to enter the scene, then I have the right to include you among the suspects." ”

"The badge of the Sherlock Detective Agency!" The governess screamed again in surprise, then sat down on the ground in disappointment, and cried, "How could he die?" ”

"Xiao Xun, comfort the teacher; Wan'er, don't let people come in again; Xiaojie, come with me to the scene. After Zheng Hanfei arranged everything, he took out two pairs of gloves from his pocket, handed one to Gu Jie, and pulled him into the murder scene.

"Huh~ Is this a suicide?" After the two teamed up to get the body down, Gu Jie glanced at Zheng Hanfei, who was squatting next to the corpse and was observing carefully, and asked.

"No, he killed him!" Zheng Hanfei pointed to the marks on the deceased's neck and said, "There are two strangulation marks on the deceased's neck, one deep and one shallow, which shows that he was strangled to death and then disguised himself as hanging." ”

"That's it!" Gu Jie looked at the cardboard box that had been kicked over on the ground and said, "It seems that the murderer wanted to disguise a suicide scene, but he ignored the most crucial step. ”

After saying that, Gu Jie remembered something, so he walked around the chemistry laboratory and said, "Xiaofei, this place is locked!" ”

"I see!" Zheng Hanfei nodded first, then looked at the deceased's eyes, lifted the deceased's clothes, and finally stood up and analyzed, "The deceased's cornea is transparent, there are no corpse spots and corpse stiffness, and he died about an hour ago, that is, from eleven o'clock to twelve o'clock." ”

"From 11:20 to 12:00 to be exact." A familiar voice came from outside the door, "Because at 11:10 there were witnesses who saw the deceased." ”

"Yo, you're finally here!" Zheng Hanfei glanced at Ouyang Xiu and said, "Where did you go up, you actually put aside the crime scene, aren't you afraid that the murderer will return to the scene to destroy the traces?" ”

"Hehe, I heard screams upstairs, so I ran up." Ouyang Xiu said with some embarrassment, "As for the murderer returning to the scene to destroy the traces?" I'm not worried about this, after all, it will take you a maximum of a minute to get here from the door of the school building, what can the murderer do in such a short time? Even if he did, he would have run into you. ”

"Do you have confidence in us?"

"Yes to you." Ouyang Xiu corrected, "You and I are the same kind of people, as long as you encounter a murder, you will definitely run over as fast as possible." ”

"That's why you told Wan'er that you had a murder case!"

"That's right!"

"Then tell me about it." Zheng Hanfei shrugged his shoulders a little helplessly and said, "The situation on the scene before we came. ”

"No problem." Ouyang Xiu nodded and recalled, "The door was locked when we arrived here, because the key to the chemical laboratory was only worn by the deceased, and I had an ominous premonition about this phenomenon of knocking on the door, so I slammed the door open, and found that the deceased had hanged himself, and as soon as he called you with his badge, he heard screams coming from upstairs, so he ran upstairs, and as for what happened next, you will know." ”

"Could it be a murder in a closed room?"

"What?"

"Gujie just walked around the scene and found that the places where I could get out were locked, and I found the keys from the waistband of the deceased's trousers." While speaking, Zheng Hanfei took out the set of keys and showed them to Ouyang Xiu, "I have already asked Gu Jie to try it just now, and they are all the keys here." ”

"I see." Ouyang Xiu smiled, "I remember that this key doesn't seem to have a backup, and it's completely in the hands of the deceased. In this case, combined with what happened to me before, it would be a real murder in a closed room. ”

"Heh, I didn't expect Diluo to perform a secret room disappearance before, but now he has a secret room to kill, what kind of reason is this."

"Stop complaining!" Ouyang Xiu patted Zheng Hanfei on the shoulder and said, "The matter at hand is to solve this case, after all, this is a case that happened in Quinn Academy, if it is not solved well, it can insult the reputation of Quinn Academy and Sherlock Detective Agency, and even more insult your reputation, you definitely don't want such a thing to happen." ”

"That's right! By the way, you just said 'you', could it be you and the vice president of this society? ”

"And one more! His name was Li He, and he was a physical education teacher, what I call an eyewitness, and he saw the deceased walk in at 11:10. ”

"I see." Zheng Hanfei nodded, with a hint of disappointment in his eyes, so far, the information he had so far could not allow him to determine who the suspect was.

"May I ask, what happened when you ran up to the seventh floor?" At this time, Zheng Hanfei thought of Ouyang Xiu's incident that he had run to the seventh floor, so he asked, in this, there are very likely clues related to the murder.

"It seems that a computer in the computer room upstairs suddenly spontaneously combusted, so the teacher there suddenly shouted, it seems that she is new, as for the name, it seems to be Lin Jiarui."

"That's it!" Zheng Hanfei pinched his chin, although this clue has nothing to do with the case, he vaguely feels that it is inextricably linked to the case, it can be said that this is his sixth sense as a detective.

"Hugh, the police have arrived, and Inspector Zhou Zheng is also inside." While the two were thinking, a gentle voice sounded in Zheng Hanfei's ears, making him feel a sense of familiarity, and he couldn't help but look towards the door.

The next moment, his pupils shrank slightly, his breathing was slightly rapid, and he shouted, "Menghan?!" ”
