It is impossible to climb over a wall.

There is an alley less than two meters wide between the wall and the building. For some reason, the ground is wet. Under the light of the flashlight, you can see many footprints, which are quite muddy.

"Some of them are still wet. Does anyone walk back and forth here?" Conan looked down.

"If there was a real murderer who framed the Daling, would he have taken the gun away secretly?" Kogoro Mouri guessed.

Conan looked up at Ryosuke Origata, "Do you remember when the gun was thrown away, did something happen in the building?"

"It doesn't seem to be." Ryosuke Orira scratched his head and said stutteringly: "Because I was very panicked at that time, I just thought about running away, so..."

"Are you okay?" Kogoro Mouri curled his lips.

"But I seem to hear something running." Ryosuke Orira was eager to prove himself, "It should be here."

"That's it." Conan raised his head and looked at the towering building, thinking.

When he walked to the main entrance again, Kogoro Mouri couldn't help but say, "It seems that he had a waste of time, and maybe this guy was lying."

When Daling Liangsuke heard this, he didn't even want to argue. After all, even he himself thought he had really killed someone.

But Conan ran to the security room at the door, knocked on the window, and woke up the security guard who was dozing off.

The latter opened the window and was very impatient, "What are you doing, you stinky little guy?"

"It's Uncle Maori." Conan said very modestly: "Can you ask the security guard to help me?"

"Maori?" The security guard was stunned for a moment, and then saw a mustache with a tugged face.

"Mr. Kogoro Mouri!" he said in surprise.

"Ah, it's just the way down." Kogoro Mouri subconsciously responded.

As soon as he finished speaking, the security guard rushed to the front, looked him up and down, and said with admiration: "It's really you. I didn't expect that one day I would actually see a living person. I'm so honored."

Seeing his incoherent look, Kogoro Mouri's mouth twitched, saying that what you usually see is not alive?

"If you have anything to do, just give me instructions." The security guard said seriously: "To be honest, I actually want to be a detective, and I can quit my current job immediately. I wonder if the master is willing to accept me as your assistant?"

Master? Chen Xing suddenly thought of Teacher Zhizhen. He hadn't contacted him for a while and didn't know how his sunscreen oil was sold.

But Kogoro Mouri, who was treated so respectfully for the first time, was inevitably a little fluttering. When his tongue grew, he was about to start making a fool of himself.

Conan immediately said, "We want to go upstairs and take a look."

"The roof, now?" The security guard looked at Kogoro Mouri as if confirming.

Kogoro Mori glared at Conan with dissatisfaction, but said seriously: "Because a case is being investigated, so..."

"Needless to say, I understand." The security guard's expression was somber, "Please come with me."

Looking at the security guard who was leading the way and was very vigilantly observing the role of the security guard, Kogoro Mouri felt a little apologized. He was not doubting his ability, but he felt that he had not done enough.

--We must continue to work hard in the future, rise up, Kogoro!

After the group went up to the rooftop, Conan looked around, then pointed to the rooftop and asked, "That should be a machine for cleaning the windows, right?"

"Don't touch it, little dear!" The security guard's attitude towards others was not so polite.

When Kogoro Maori heard this, he immediately said, "You don't need to speak so much!"

"Yes!" The security guard stood at attention quickly.

Conan held back his smile and said, "This should be up and down the window tracks of the building, right?"

"You are right, young master." The security guard trotted over, very terrible.

"Is it fully automatic?" Conan asked.

"That's exactly that." The security guard smiled.

Conan's eyelids shook, "So did you brush the window last night?"

"It's been wiped." The security guard nodded, "It's a window near the alley. If you wipe it during the day, the cleaner will flow down, which may cause trouble to the working office workers, so it will do it at night."

"As it turns out, the soil on the ground is wet because of the detergent." After thinking it through, Conan began to search around the roof.

"Are you looking for this?" Chen Xing walked out of the corner, with a black revolver wrapped in a tissue in his palm.

"Where did you find it?" Conan said in surprise.

"The corner over there." Chen Xing said casually.

Conan showed a 'as it really' smile.

--Last night, just when Mr. Dacheng threw away his gun, the automatic window cleaning machine was in operation, so the gun he threw was just on the lower automatic window cleaning machine. After the operation was over, the pistol fell here as the pistol returned to the roof.

When he went back, the smile on Kogoro Mouri's face was a little stiff, all because of the reluctant and enthusiastic security guard.

"It's really a headache. It turns out that having fans is quite painful." He rubbed his face and a little bit Versailles.

The few people in the car pretended that they didn't hear it.

...

Dr. Agasa's house.

"Although this gun is very fine, the bullet is indeed fake."

There were disassembled revolvers and bullets on the table. Dr. Agasa used tweezers to pick up the bullet case. "Although there was gunpowder in the shell, there would be gunfire when firing, the bullet would become shattered under the impact."

After watching from the side, Chen Xing nodded secretly.

Kogoro Maori asked, "Then why will President Nda die?"

"Someone must have shot him," Conan said, "It was the real murderer who hid somewhere in the park at that time."

"What?"

"At the moment Mr. Great Leader shot out the empty bullet, the murderer also shot and killed Mr. Enda at the same time." Conan said.

"So that's it." Kogoro Maori pondered: "So, based on my investigation, there should be three suspicious characters so far. Kaneshiro Kazuichi, who is responsible for game research and development, President Enda's secretary Momoko Kamiya, and the company's vice president Tomoko Kanda.

Because of money, Kinshan has always had some disputes with Mr. Enda; Mako Umiya is probably a relationship entanglement; Kanda has always been oppressed by President Enda's power."

Conan said: "But President Enda has also caused a lot of trouble because of his work, right?"

"That's right, he has many enemies." Kogoro Mouri nodded subconsciously, but immediately raised his eyebrows, "You little brat, don't be too arrogant."

Conan hugged his arm and was very arrogant.

"How did you find the website you bought guns online?" Kogoro Mouri suddenly patted Ryosuke Orinata on the shoulder.

The latter was sitting comfortably on the sofa with his legs crossed, and was suddenly startled.

"Well..." He hesitated a little.

Seeing this, Kogoro Mouri went up to lock his throat, "What else do you want to hide? Tell me honestly!"

"It was Taozi who found it!" Daling Ryosuke said hurriedly.

"What?" Kogoro Mouri frowned.

"Because we all know that Nda was once a candidate judo player for the Olympics, she said I would be better off with a pistol on me, so she told me the website of the gun fan." Ryosuke Orira rubbed his neck and said.

"Ha, so that's it!" After Kogoro Mouri's sudden enlightenment, he pointed at Conan, "Don't force yourself, the time for the child is over."

After saying that, the person left casually.
