Conan: The Mechanic

"You..." Nana Koyama was at a loss for words, so she could only lose her temper.

"We'd better focus on other things," Conan diverted the topic. "Like a safety gate or something. We can get out of there, right?"

"The safety exit is in the kitchen," Shiratori Ren Saburo said. "Mr. Mori and I will check it out and call everyone back if it works."

"..." Qianyu frowned, because he believed that as a person with a brain, Mr. Murakami would never make such a mistake that did not damage the escape exit.

Sure enough, when Officer Shiratori and Uncle Maori came back, they brought a piece of news—the safety port was sealed with cement from the outside, and only a small crack could be opened. They tried to push the door open, but in the end they had no choice but to bring a cement bag dragged in from outside the door. The label above shows that this is cement labeled 525 for the floor slab

"Cement?" Qian Yu was stunned.

The idea of ​​cement is really stupid!

Just now, he glanced at the wall that blocked the passage, which was obviously the most common mechanism of rolling shutter doors in shopping malls. When they came in from the passage just now, Qianyu could confirm that there was no button that could control this mechanism in the passage, so there were only buttons that could control this mechanism. . .

Chiba focused her gaze on the control panel next to the wall.

However, the operating panel has been severely damaged, and this circuit damage cannot be repaired under the existing conditions.

Then, something subtle happened.

1. This channel can only be closed internally.

2. The safety gate was sealed with cement. This kind of thing solidifies very slowly. Now that the safety gate can be sealed, it is impossible for Mr. Murakami to leave from here.

3. There is no other exit.

The conclusion is. . . Murakami is still here.

"It's not good..." Qianyu frowned, and it felt terrible to be in the same space with the murderer.

At this moment, Qianyu smelled the smell of nail polish.

Did someone just put on nail polish?

Qianyu subconsciously looked at the only person here who might have just painted her nails.

Sure enough, Oyamauchi Nana's fingernails appeared a different color than before.

"Sister, did you just apply your nail polish?" Qianyu asked.

"..." Oyamauchi Nana was obviously still concerned about what happened just now, and answered after a moment of psychological struggle (probably not having the same knowledge as a child). "It's the kind of nail polish that Mr. Xu Shengyi attached to the invitation. It's a very precious kind."

"From Mr. Xu Shengyi..." Qian Yu's brows twitched.

He thought of something terrifying

Since it takes 3 days for the 525 cement behind the safety door to solidify, and the cement has been able to withstand manpower, it means that the cement has been piled there three days ago. (As I said before, Chiba University majored in civil engineering in addition to mechanical engineering.)

But Mr. Murakami has just been released from prison for less than two and a half days! Even if he came to lay out the cement immediately after he was released from prison, the cement would not be completely solidified!

Then, who blocked the security gate here! ! ! ? ? ?

Chiba subconsciously walked out of the crowd because he had reached the final conclusion.

The murderer is among them!

There is absolutely no way to go on like this. Because there is no way to get out of here now, everyone will be trapped here.

In other words, the murderer planned to kill them all before trying to find another way to get out. . .

When Qianyu came back to his senses, he found that Kogoro Mouri and Officer Meguro were gone, as were the other adult males! (Including Kudo Shinichi who is 17 years old and three years old)

"Where are they?" Qian Yu asked in surprise.

"What were you thinking just now?" Conan asked. "They're looking for an exit."

"Looking for an exit?" Before Qianyu could react, the lights around her suddenly went out.

power cut? How come at such a time?

In the darkness, a patch of violet was in sight. Nana Koyama's varnished fingernails are starting to shine brightly!

"Sister, clench your hands into fists and put them in your pockets!" Qianyu shouted hurriedly.

"Ah?" Nana Koyama was obviously in fear of the darkness, and didn't hear what Chiba said at all.

This guy. . . How can you drop the chain at such a critical moment?

but. . . If it wasn't for the unusual light on Nana Koyama's hand to attract his attention, he would probably panic a little too?

"Clap!" The sound of glass shattering resounded between Nana Koyama and Chiba.

"Ahhhh!!!" Nana Oyama's poor psychological quality was exposed, waving her arms in the air in a panic, and ran into the distance.

"Sister come back soon!" Qianyu was horrified.

With her fingernails so conspicuous, she was still yelling, was she afraid that the attacker wouldn't be able to kill her?

"Ahhh!" Chiyu responded with a scream, and a violet light that fell from the sky to the ground.

"What's going on?" After a burst of hurried footsteps, Kogoro Mouri's questioning voice came.

"Miss Koyama Nana was attacked!" Conan said.

"Pa-da!" With the sound of a switch ~www.readwn.com~ the watch on Conan's wrist emitted a dim light, illuminating the area in front of Qianyu's eyes.

"Bastard!" Qianyu gritted her teeth.

With a knife stuck in Nana's back, Koyama Uchi fell to the ground with no vitality.

With the restoration of the lights, Mouri Kogoro, Maurilan and others who were present saw Nana's death.

"Cut!" Kogoro Mori said angrily. "The **** Murakami-jo!"

"What happened?" Sawagi Toshiro, Shinto Nagai and the others also rushed over at this time, and they were shocked when they saw Nana's body in Koyama.

"I don't know who cut off the electric switch!" Officer Mumu, who finally arrived, said angrily. "It must be Mr. Murakami!"

"We'd better get out of here as soon as possible, otherwise we might all die here!" Qian Yu said solemnly. "We have to destroy this wall or that security door!"

"Do you want us to hit the wall?" Kogoro Mouri said speechlessly. "This is too unreliable!"

"It's necessary to hit the wall, but we don't need to hit the wall!" Qianyu shrugged. "We still have this!"

Chiba pointed to the Ferrari F40 in the middle of the restaurant.

"That car should be just a decoration, right?" Shido Yongming asked. "There should be no gasoline in it."

"But we still have cooking oil!" Qian Yu reminded.

"Edible oil is heavy oil," Conan shook his head. "If the gasoline engine of the Ferrari F40 uses heavy fuel oil..."

As he spoke, Conan's expression became subtle.

"I know that the oil pipe will be blocked soon, and the car will also strike soon," Chiba spread her hands. "But we only need the sports car to complete one charge, a charge of sufficient intensity."
