Chiba decides to break away from the group and go it alone - because he has an idea of his own, which is clearly not in sync with the others.

Well, although it is said to be acting alone, it seems that it is completely impossible to do at this time, as for the reason......

"You're going to check the duty roster?" Walking beside Qianyu, Gray Yuan said curiously. "Are you...... Think the virus was transported to the airship yesterday, so you suspect that there are ghosts in the staff? ”

"Yes," Chiba nodded. "This is the most plausible explanation, otherwise it would have been almost impossible to ship a large enough amount of methamphetamine in sufficient quantities for one person to miss an entire bag of methamphetamine in complete secrecy."

"Any more granular goals?" Gray Plains asked. "If the procedure we saw a few days ago is correct, there should be a lot of people working on the whole inspection process at the same time, right? If none of them found methamphetamine, doesn't that mean that there are a lot of ghosts inside? ”

"Not really," Qian Yu shook her head. "In addition to the taste, that bag of methamphetamine itself is quite similar to ordinary rock candy. If you are not familiar with food, you may not realize the difference at all. Even if you seal the smell of methamphetamine and put it in front of them, many people can't recognize it at all - don't look at me like that, you're an expert, so you can recognize it, and ordinary people can't distinguish between rookies at all. ”

"Perhaps," Gray Hara shrugged. "So, how are you going to distinguish which of the many people who handle those materials is an inner ghost?"

"I don't know," Qian Yu continued to shake her head without hesitation. "So when the time comes, let's look at the names in the roster. It is not enough to get enough information based on the information that is available now. ”

"Will you be able to get enough information in that case?"

"Not necessarily, but if you go to the loading port of the cargo with the information and carefully check the specific process, there is probably a greater probability that we will deduce the information we need.

……

Cargo loading port.

"It should be here," Qian Yu pouted as he came to the loading port to send the goods into the storage compartment with Gray Yuan Ai. "Well, I'll admit it's a pretty technical security system — of course, it means that there are definitely insiders in these systems, otherwise methamphetamine wouldn't have been able to fly safely."

With that, the two men began the inspection at the very beginning of the conveyor belt, where the goods were sent into the security system.

"If the measures they gave me are correct, not all machines will be turned on when checking the rock candy," Chiba and Ashbara Ai stood on either side of the conveyor belt, placing one hand on the conveyor belt together, and gently swiping their fingertips across the conveyor belt as they walked, making a rhythmic grinding sound. "In other words, there are only a few machines that can be opened, and there are ...... machines that have the ability to check that the bag contains methamphetamine instead of rock candy."

"This security scanner at the beginning," Gray Plains looked at the security scanner in front of them. "And ......"

"It's gone," Qian Yu said after glancing at it. "The rest of the procedure is just a flotation tank to check the tightness and a pulse sterilizer, neither of which has the ability to check the contents."

"Who's in charge of the security screen?" Gray Yuan Wai reacted immediately.

"Staff," Chiba shrugged. "Anyway, it's always a good idea to go and find that staff member. However, just in case, you need to find Uncle Jiroyoshi to get the necessary authorization before that, otherwise you may be in trouble. ”

……

"Suzuki advisor?" The female employee looked at the warrant in her hand and was stunned for a moment. "You ...... How can there be a warrant from a Suzuki consultant? ”

"Of course, because Advisor Suzuki gave us permission to ask you questions," Chiba said. "So, can we start asking, Ms. Kawasaki?"

"What do you want to ask?" Miss Kawasaki asked with a sigh. "Say, I know everything."

"Where were you last night when the airship was on cargo loading mission?" Qian Yu asked.

"I'm controlling the security machine," Kawasaki frowned slightly. "You've all come to me so excitedly, haven't you even investigated this?"

"So, did you detect anything unusual?" Qian Yu asked again. "Let's say the security scanner found something strange or something."

"Strange stuff?" Kawasaki's expression seemed to indicate that she didn't know anything. "What kind of strange thing? If there was anything strange going through security, I don't know, but at least the alarm didn't go off at all. ”

“？” Qian Yu frowned. "No alarms?"

"What kind of weird thing are you asking?" Miss Kawasaki asked rhetorically. "Can you at least give me a range? I don't have a clue if you ask me directly. ”

"All kinds of things are fine," Qian Yu paused halfway through the sentence, and then turned on the contrast system and video system of the auxiliary unit. "I'll give you an example, think about it."

"Okay."

"Did you see any dangerous items like knives or guns going through security?" Chiba asked the first question.

"Nope."

"Has the scanner been turned off for some reason, creating a potential situation where some goods are taken on the airship without passing through the scanner?" Qianyu continued to ask.

"I want to ...... Probably not. ”

"So, have you ever brought anything with yourself to the security screen, or acquiesced in what goods didn't pass through the security screen?" Chiba didn't seem to be satisfied with the way Kawasaki answered just now. "I will answer with the most straightforward affirmative or negative words, and no other part is needed."

"Nope."

"Okay," Chiba nodded. "So, did you check the rock candy you brought with you yesterday?"

"Yes."

"Did you check all the rock candy last night?" Qianyu continued to ask. "I didn't miss a single bag of rock candy, right?"

"Yes."

"Did you notice that the rock candy you went through yesterday was actually methamphetamine?" Qian Yu still asked such a question with the same indifferent tone as before.

"Huh?" Kawasaki seemed to have completely forgotten her previous request for only the simplest affirmative or negative answer, and lost her voice. "Ice?"

"......" Qianyu frowned slightly—of course, not because Kawasaki's way of answering was unexpected, but because according to the analysis of the video footage of the auxiliary unit, Kawasaki's surprise now was genuine surprise, and it was by no means something pretended.

"Just kidding," Qian Yu immediately shook her head. "I just wanted to ask you if you can be sure that no one was sneaking anything on board."

"I can't." Startled, Kawasaki paused for a moment before replying, his tone similar to before.
