Qianyu decided to leave the team and acted alone - because he had his own idea, which was obviously not synchronized with others.

Well, although it was just acting alone, it seemed that this was completely impossible to do it at this time. As for the reasons...

"You want to check the duty list?" Walking beside Qianyu, Ai Haibara said curiously. "Do you... think the virus was transported onto the airship yesterday, so you suspect there is an insider in the staff?"

"Yes," Qianyu nodded. "This is the most reasonable explanation, otherwise it would be almost impossible for a person to miss a whole bag of methamphetamine to transport it with complete confidentiality."

"Is there any more detailed goal?" asked Ai Haibara. "If the procedure we saw was correct a few days ago, there should be many people handling the entire inspection process at the same time, right? If they did not show methamphetamine, wouldn't that mean there were many insiders?"

"Not to it," Qian Yu shook his head. "The bag of methamphetamine is quite similar to ordinary rock sugar in addition to the taste. If it is an ordinary person who is not familiar with food, he may not realize the difference. Even if the methamphetamine is sealed and placed in front of them, many people cannot recognize it at all - don't look at me like this, you are an expert, so you can recognize it. The rookie like ordinary people cannot distinguish it at all."

"Maybe," Haibara Ai shrugged. "So, how do you distinguish which of the many people who are in charge of those materials is an insider?"

"I don't know," Qianyu continued to shake his head without hesitation. "So look at the names in the roster and talk about them. If you only rely on the information you have now, you will not be able to get enough information."

"Will you get enough information then?"

"Not necessarily, but if you take the information to the loading port of the cargo and carefully check the specific process, there will probably be a greater probability of inferring the information we need.

...

Cargo loading port.

"It should be here," he came to the loading port where the cargo was delivered into the storage compartment. Qianyu looked at the complex machine group here and curled his lips. "Well, I admit that this is a very technical security inspection system - of course, this also means that there are definitely insiders in these systems, otherwise even if methamphetamine can fly, it would not be possible to pass the inspection safely."

As he said this, the two people started to inspect from the beginning of the conveyor belt, that is, where the goods were sent to the security inspection system.

"If the measures they gave were not wrong, not all machines would be opened when checking rock sugar," Chiayu and Ai Haibara stood on both sides of the conveyor belt, putting one hand on the conveyor belt together, and while walking, they gently stroked their fingertips on the conveyor belt, making a rhythmic friction sound. "In other words, there are not many machines that can open, and there are machines that have the ability to check that the rock sugar bag contains methamphetamine instead of rock sugar..."

"The security checker at the beginning," Haibara Ai looked at the security checker in front of them. "And..."

"There is nothing behind," Qian Yu said after a glance. "There are only one floating tank to check seals and a pulse sterilizer. Both of these have the ability to check contents."

"Who is responsible for the security check?" Haibara Ai immediately reacted.

"Staff," Qianyu shrugged. "Anyway, it's always right to find that staff member. But just in case, you need to find Uncle Langji to obtain the necessary authorization before this, otherwise there may be trouble."

...

"Consultant Suzuki?" The female employee looked at the warrant in her hand and was stunned for a moment. "How come you...why will you have the warrant from Consultant Suzuki?"

"Of course we're here to ask you questions because Suzuki consultant allowed us to ask," Chiba spread his hands. "So, can we start asking, Miss Kawasaki?"

"What do you want to ask?" Miss Kawasaki sighed and asked. "Speak, I know everything."

"Where were you when the airship was carrying out the cargo loading mission last night?" Qianyu asked.

“I’m controlling the security machine,”

Kawasaki frowned slightly. "You have all come to me so hard, have you not even investigated this?"

"So, have you checked for any abnormality?" Qian Yu asked again. "For example, something strange appeared in the security checkpoint."

"Strange thing?" Kawasaki's expression seemed to indicate that she knew nothing. "What kind of strange thing? If there is anything strange thing passing the security check, I don't know, but at least the alarm has not sounded at all."

"?" Qian Yu frowned. "There hasn't been any alarm?"

"What kind of strange thing are you asking?" Miss Kawasaki asked back. "Can you give me at least one range? I have no idea if you ask directly like this."

"All things are OK," Qian Yu paused halfway through, and then turned on the comparison system and video recording system of the auxiliary unit. "I'll give an example, think about it."

"OK."

"Have you seen any dangerous items such as knives or guns pass the security check?" Qian Yu asked for the first time.

"No."

"Has the security checker been turned off for some reason in the middle of the process, resulting in potential situations where some goods were taken on the airship before passing through the security checker?" Qian Yu continued to ask.

"I think...it shouldn't be."

"So, have you brought something through the security checker yourself, or have you acquiesced to the situation where the goods did not pass the security checker?" Chiyu seemed not satisfied with the sentence structure Kawasaki answered just now. "I answered the most straightforward affirmation or negative words, and there was no need for any other part."

"No."

"Okay," Qianyu nodded. "So, did you check the rock candy you brought on the airship yesterday?"

"have."

"Did you check all the rock candies last night?" Qian Yu continued to ask. "No bag of rock candies should be missed, right?"

"right."

"Do you have any rock candies you conducted security check yesterday are actually methamphetamine?" Qian Yu asked such a question with the calm tone he had before.

"Ah?" Kawasaki seemed to have completely forgotten what she had requested before, and said in a lost voice. "Method?"

"..." Qianyu frowned slightly - of course, it was not because Kawasaki's answer was beyond his expectations, but because based on the analysis of the video of the auxiliary unit, Kawasaki's current surprise was real surprise, and it was definitely not something that was pretended.

"Just kidding," Qian Yu shook his head immediately. "I just wanted to ask you if you can be sure that no one has taken something on the boat."
