Conan: The Mechanic

"You guys stand back," Qianyu stretched the hook part of the Wuhen Umbrella (used for abseiling in Yiyu Building, remember?) through the hole, and then tried to pull it from the floor tile where the small hole was located. stand up.

As the floor tiles were pulled up, a secret passage hole appeared in front of everyone. The stench of the corpse almost made Qianyu retire, and Yuan Tai behind him even felt nauseous because of the pungent smell.

"Go to the grass to vomit!" Qianyu ordered quickly - if he was allowed to vomit here, once the master of the secret passage came here, he would definitely doubt whether someone had broken in.

A minute later, Yuan Tai walked back with a look of collapse, and the others were somewhat used to the smell.

"This is a stone-colored wooden door..." Conan tried to shake the floor tiles after Qianyu took back his umbrella, and found that the weight and feel were very subtle.

"I'll take the lead," Qian Yu glanced at the darkness below. "Queen Conan, the others are between the two of us."

However, before going down, Qianyu, who just brought her face close to the entrance of the cave, felt that she couldn't breathe at all, so she hurriedly moved away from the entrance of the cave.

"This **** place..." Qianyu breathed out a breath and complained. "It's all carbon dioxide!"

"Is there any creature suffocating in it..." Conan frowned. "Can the flashlight shine down below?"

"Where is the flashlight?" Yuan Tai was stunned.

"Didn't you bring it?" Taking out a flashlight, Qianyu shone the light below the entrance of the cave.

Below the entrance of the cave is an underground secret room, and on the ground of the secret room, a highly corrupted corpse is lying flat on the ground. Notably, the corpse's hands were pressed against the chest and the legs were curled.

"Looks like," Conan came to Qianyu, glanced down, and immediately reacted. "This is the true master of suffocation."

"Long hair, adult-sized corpse with corruption, presumably female, has been dead for a while."

"The soft tissue of the corpse began to erode, and the death time exceeded 13 days. Considering the anaerobic environment here, the decay rate should be slowed down by 50% to 60%, and the death time of the deceased was about 30 to 35 days ago." Conan closed the wooden door again. , said. "April 5th to 10th—"

Conan's expression suddenly became very strange, and his words became hesitant.

"Is there anything wrong?" Qianyu keenly discovered Conan's anomaly.

"No...Nothing..." Cold sweat broke out on Conan's head. "Let's go to the police, and then go to the teaching building to see."

"Okay, we—" Qian Yu was interrupted halfway through speaking.

"Crack!" The teaching building made a heavy sound of closing the windows—someone is in the teaching building!

Qianyu and Conan glanced at each other with fear of the unknown in their eyes.

"Wait a minute..." Conan closed his eyes and said with a deep breath. "If it was a corpse a month ago, then the person in the school building is probably not the murderer. Also, if it was suffocation, it might not have been man-made. After all, this method of death is unreliable and unreliable. It's not quick, normal people would never kill people in this way."

"Maybe the killer's strength is not enough to subdue this woman? Physical strength is insufficient or disabled?" Qian Yu suggested that it was possible.

"There are too many people who meet this requirement in elementary school..." Conan pouted. "The principal's grandfather and other old men all meet this condition, and so do female teachers. Even if they admit death, all students are within the scope of suspects."

"How many people know about this place?" Qian Yu glanced in the direction of the secret room. "Since it was built here, it means that it should have been built when the site was just completed. But the teachers will be rotated, and there are too few people who worked in Didan when the school was established. ——The principal, the dean of education, and the teachers who have returned from individual rotations should be in single digits."

"Send them out of school first," Conan made a decision. "Then we two go to see."

"Why - oh..." Yuan Taizheng was planning to exercise his right to act freely, but in the silent gaze of Qianyu, he chose to shut up - Qianyu has reiterated many times before that only he and Conan have the right to act Now, Mrs. Yuan couldn't speak to him, so she had no choice but to listen to Qianyu's words, at least on the surface.

. . .

"The door is locked..." Qian Yu said helplessly, looking at the school gate in front of her.

"The uncle of the doorman who is always useless at this critical time is really..." Conan pouted.

"Then what should I do?" Qian Yu asked with a frown. "Anyway, I can't open the lock. If I forcefully break the door, I will get into trouble. The isolation design of this school is really disgusting. The six-meter-high school gate and the four-meter-high wall can't be climbed at all."

"..." Conan thought for a while, then pointed to a building next to him. "Take them where they shouldn't encounter intruders."

"Physical Education Teaching and Research Office?" Qian Yu was surprised. "I know the door of the sports teaching and research room is broken, so I can go in. But are you sure you won't meet anyone?"

"The seniors who were here 30 years ago generally have their own offices. After all, as long as they don't retire, they are managers big or small." Conan shrugged. "But you also know the situation of the physical education teacher. He eats young, so he must not have senior qualifications. If the murderer has his own office, why should he come to the physical education teaching and research office?"

"Ding ding—" A sound suddenly appeared on Qian Yu's body~www.wuxiahere.com~ What sound? cell phone? "Conan asked curiously.

"If it's a mobile phone," Qianyu rolled her eyes. "I've already called the police! It's a sensor."

Saying that, Chiba took out a box from her backpack, and a signal light board was installed in the plastic case on one side of the box.

"Someone came out of the management staff's office area," Qian Yu explained as she watched a light come on. "But I don't know who it is. There is a door lock in the management office area, so I can't get in."

"Anyway, it's not good..." Conan said speechlessly. "This time is still here, and I may have worked in Didan for 30 years... I am afraid that we have met the person we are looking for."

"Upstairs," Qianyu read while walking towards the sports teaching and research room with three incompetent little guys. "Looks like it's going to the fifth or sixth floor."

"Good news," Conan shrugged. "Anyway, he couldn't escape the teaching building from the top floor."

. . .

After placing the three little guys in the sports teaching and research room, Conan realized that Qianyu's face had turned extremely bad. "Did something happen?"

"Either my eyes are hallucinating, or else it's hell." Qian Yu turned the signal light board she had been looking at to Conan.

The small sensor light on the stairs on the sixth floor turned on, but just one second later, the small sensor light on the stairs on the third floor came on. A few seconds later, the small sensor light at the entrance of Class A of Grade 6 turned on, and two seconds later, the small sensor light at the entrance of Class A of Grade 3 actually turned on.

"No...you don't have vision, and we don't see a ghost..." Although he said that, Conan did have a "living to hell" expression on his face.

"We met two uninvited guests..."
