"You..." Nana Koyamauchi was speechless for a while, and she could only lose her temper indiscriminately.

"We'd better focus on something else," Conan digressed. "Like safety openings and stuff like that. We can just get away from there, right? ”

"The safety opening is in the kitchen," Shiratori Renzaburo said. "I'm going to check it out with Mr. Maori and I'll come back and call everyone if we can use it."

“。。。” Chiba frowned, because he believed that as a man with brains, Murakami would never make such a mistake without damaging the escape exit.

Sure enough, when Officer Shiratori and Uncle Mori returned, they brought the news that the security opening had been 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 that had been dragged in through the door. The number above indicates that this is cement with a grade 525 used to lay the floor slab

"Cement?" Qian Yu was stunned.

The idea of cement is really stupid!

He glanced at the wall that sealed the passageway, and it was apparently the most common roller shutter pattern mechanism in a mall. And when they came in from the passage just now, Qian Yu could confirm that there was no button in the passage that could control this mechanism, so the only button that could control this mechanism was...

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

However, the operating panel had been badly damaged, and the circuit damage was irreparable under existing conditions.

Well, something delicate happened.

1. This channel can only be closed from the inside.

2. The safety entrance is sealed with cement, and the solidification of this kind of thing is very slow, and since the safety door can be sealed now, it is impossible for Murakami to leave from here.

3. There is no other exit.

The conclusion is ... Murakami is still here.

"It's not good..."Chiba frowned, it felt terrible to be in the same space as the killer.

At this moment, Qian Yu smelled a smell of nail polish.

Has anyone just put on nail polish?

Qian Yu subconsciously looked at the only person here who might have just put on nail polish.

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

"Sister, your nail polish was just applied?" Qian Yu asked.

“。。。” Nana Koyamauchi was obviously still minding what had just happened, and only replied after a moment of psychological struggle (probably not like a child). "It's the nail polish that Mr. Asahi Katsuyoshi attached to the invitation, and it's a very expensive one."

"Mr. Xu Shengyi sent it... Qianyu's brow twitched.

He thought of a hair-raising thing

Since it takes up to 3 days for the cement to solidify behind the security gate, and the cement has been able to withstand manpower, it means that the cement has been piled up there three days ago. (As I said before, Senwa University also studied civil engineering in addition to mechanical engineering.) ）

But Murakami has only 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 have completely solidified!

So, who sealed the security gate here!!???

Chiba subconsciously walked out of the crowd as he got the final conclusion.

The murderer is in the midst of them!

This is not the way to go. Because there is no way to get out of here now, everyone will be trapped here.

Or rather, the murderer plans to kill them all and then find another way to get out...

When Chiba comes back to his senses, he discovers that Mori Kogoro and Officer Twilight are gone, as are the other adult males! (Including 17-year-old and Shinichi Kudo, who has only come of age for three years)

"What about them?" Qian Yu said in surprise.

"What were you thinking?" Conan asked. "They're going to find the exit."

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

Blackout? How can it be at such a time?

In the darkness, a violet color came into view. Nana Koyamauchi's nails with nail polish begin to shine brightly!

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

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

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

But... If it weren't for the abnormal light on Nana Koyamauchi's hand that attracted his attention, he probably would have been a little panicked, right?

"Smack!" The sound of shattering glass sounded between Nana Koyamauchi and Chiba.

"Ahhh!!h Nana Koyamauchi's poor psychological qualities were exposed, and she waved her arms in the air in a panic and ran into the distance.

"Sister, come back!" A thousand feathers were horrified.

The fingernails are so conspicuous, and she is still yelling, is this because she is afraid that the attacker will not be able to kill her?

"Ahhh In response to Thousand Feathers, there was a scream, and a violet glow that slipped from the sky to the ground.

"What's going on?" After a rush of footsteps, Mori Kogoro's inquiry came.

"Nana Koyamauchi-sama has been attacked!" Conan said.

"Smack!" With a mechanical sound, the watch on Conan's wrist emitted a dim light, illuminating the area in front of Chiba's eyes.

"Bastard!" Qian Yu gritted his teeth.

Nana Koyamauchi had a knife stuck in her back and fell to the ground, completely lifeless.

As the lights were restored, Mori Kogoro, Mori Ran and others who were present saw Nana Koyamauchi's death.

"Cut!" Maori Kogoro said angrily. "Akira Murakami, this bastard!"

"What the hell is going on?" Fair Sawaki, Shindo Masaki and others also rushed over at this time, and they were all shocked when they saw Nana Koyamauchi's body.

"I don't know who cut the electric switch!" Officer Twilight, who arrived at the end, said angrily. "It must be Akira Murakami!"

"We'd better get out of here as soon as possible, or we'll all die here!" Qian Yu said in a deep voice. "We've got to break this wall or that security door!"

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

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

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

"That car should be just an ornament, right?" Shindo asked. "There's probably no gas in there."

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

"Cooking oil is heavy oil," Conan shook his head. "If the petrol engine of the Ferrari F40 uses heavy oil...

As he spoke, Conan's expression became subtle.

"I know the oil pipes will clog up quickly, and the cars will strike quickly," said Qianyu Booth. "But we just need the car to make one charge, one charge with enough strength."
