Late at night, in a certain room, Officer Nakamori stood in the middle of a group of police officers and Mori Kogoro, looking at them solemnly.

"Although we have not found any evidence of Kidd the Monster Thief appearing on this airship so far, based on our speculation, it is very likely that he is still on the airship." With that, Officer Nakamori tapped on the clipboard beside him. "So next, we're going to talk about some ways to keep Kidd from sneaking in—the first of which is to remember your code."

As he said this, Officer Nakamori glanced at the surrounding walls.

The walls of the entire room were dark white - not because the cabin was painted in such a strange color, of course, but because Officer Nakamori had the black and white wallpaper pasted on the walls separately - to prevent the thief Kidd from sneaking into the room and then setting up surveillance equipment. The white wallpaper can completely set off any surveillance equipment that is trying to be attached to it, while the black wallpaper that is attached below the white wallpaper takes on the role of setting off the base color. As soon as the white wallpaper is damaged, they can immediately notice it and fix it.

In other words, you should not have to worry about any monitoring equipment, and everything you write is able to guarantee confidentiality.

Thinking like this, Officer Nakamori picked up a marker and spoke at the same time.

"That's what you need to remember," Officer Nakamori said, resting the tip of his marker against the clipboard. "According to your current seating order, numbered from left to right, and then your code will be this."

Meanwhile, Officer Nakamori writes quickly on the blackboard.

[Please don't make a noise when you see this text, we may have been monitored.] 】

The police officers present all looked different, but almost none of them did anything unusual - they were all veterans and knew that they could not do anything that might cause something unusual at this time. Immediately afterward, Officer Nakamori was still talking.

"Come, count from left to right, and then everyone writes down their numbers to each other." Officer Nakamori said unhurriedly, and at the same time did not stop with his hands.

[When answering the code, you can choose a number between 1 and 10 to answer, but pay attention to close your left eye when answering.] 】

"If anyone doesn't answer their number, get in on it." Officer Nakamori admonished. "You have to pay attention, Kidd the Strange Thief's disguise is very strong, so I still can't issue guns to you this time, but I have prepared the latest identification soft armor for you - I ask you to return here on time after returning to Japanese airspace, and I will put on the soft armor for you myself. It takes a long time to wear this suit, and the degree of wearing of the softnails will vary over time. ”

With that, Officer Nakamori continued to write. [These are all fakes, but you still need to come back on time and put on that soft armor, which will at least allow you to have some resistance against Kidd's mechanical weapons the Monster Thief.] 】

"So next, we need to show you how to judge," Officer Nakamori said, putting a few bars on the board. "The soft armor has six horizontal hoses on its chest, and every hour after sensing body temperature, one of the hoses is infused with a very conspicuous red liquid. If you see someone wearing the wrong number of strips of soft armor infused with red liquid, then that person must be Kidd the Monster Thief who just stripped the soft armor from your companion and put it on himself to cover it up! ”

There was some excitement on the faces of all the policemen - there was no doubt that the hose on it was not so complicated, but if someone used this to talk to other people when communicating with them, then this person must have only heard what Officer Nakamori said, but failed to see what Officer Nakamori wrote.

Just then, Officer Nakamori's cell phone rang suddenly—after he glanced at it, he put it back away as if nothing had happened.

"So, let's talk about this today, and when we get back, everyone will tell us what we just said—" Officer Nakamori tapped on the clipboard as he said this. "I'll memorize all these things, and then we'll come back to see this after lunch tomorrow."

……

About fifteen minutes later, in another room.

Officer Nakamori opened the door of one of the cabins and removed his clothes. "I'm back."

At the same time, Jiroji Suzuki, who had been waiting in the darkness for a long time, had already walked up and stood not far away. “K26943。”

“P15879。” Officer Nakamori replied immediately.

Jiroyoshi Suzuki then stepped forward and placed a scanner in front of Officer Nakamori, who immediately extended his left thumb up. After a few seconds, the scanner emits a pleasant sound and the display light flashes green.

Then, like a trick, Suzuki Jiroyoshi took out a scanner and swept it back and forth on Officer Nakamori several times.

"It's okay," Officer Nakamori breathed a sigh of relief. "If I'm loaded with something now, it's going to be a big problem."

"yes," a masked man looked at him not far away. "So, we can talk about it now."

"What did you call me back for?" Officer Nakamori asked. "Did something matter happen?"

"Yes," the masked man nodded. "We just received a communication from Guam, and then we discovered a delicate thing."

"What's the matter?" Officer Nakamori asked.

"In their hospital, in addition to Honda, there is another patient who has been removed from our airship." The masked man replied. "Now, the patient has recovered, but Honda's symptoms are still in the prognostic stage, but the medical bills we had previously called them have been used up, so they contacted us through that patient."

"Let me ask," Officer Nakamori immediately realized what that meant. "Can we still see the person who looks like that patient on the airship?"

"Yes," the masked man nodded. "In other words, I'm afraid it's our thief Mr. Kidd, and the patient who was secretly removed from the airship without our knowledge was probably sent down by the thief Kidd."

"So what should we do now?" Officer Nakamori asked. "Direct arrest."

"Not much hope," the masked man shook his head. "Kidd has a weapon like a poker gun, but you still don't have the authority to shoot him, so it's going to be very difficult for you to try to capture him. So we had to make a trap that was effective enough to capture Kidd the Thief. ”
