Pokémon: I'm a detective, not the sixth one.

After receiving the instruction, Lu Yi went straight back to the monitoring room.

Dalin contacted the owner of Lijia Hall and asked her to transfer the security personnel from Lu Yi's side due to lack of manpower. Lu Yi and the others discussed the action plan and looked up at the air outlets on the ceiling.

The department store is equipped with central air conditioning, and these intricate pipes connect each store. The search is very difficult and time is very tight. The police officers must find the criminal before the customer loses patience!

"The pipe is too narrow. My friends around me can't enter. The most I can do is let Rotom go with you." Muzi curled her mouth helplessly. She was surrounded by tall figures like the Flying Mantis and the Gotha Duck. The type of elf is not qualified for this task.

Lu Yi's situation is similar. Kadi Dog and Eluredo are seriously oversized. Little Pippi is still with Miss Nazi. The remaining Iron Arm Gun Shrimp are too weak to catch up. Get on the Little Lada.

The only thing that can be counted on at this time is the two Eevee bred in Yinchuan.

He stepped forward without hesitation: "Leave it to us. Ye Yibu and Huo Yibu have the right figures, so it shouldn't be a problem to enter the pipeline."

Lu nodded and then asked Muzi for a favor.

"You can continue to monitor the surveillance and stay here. There is no need for Rotom to support Yinchuan. Keep the news flowing at all times. Maybe we find traces of Rattata, and we need you to watch the surveillance and help us guide the way."

"Okay." Muzi accepted happily.

Lu Yi walked around the room, took two flashlights used by security guards during patrols, and pulled a few binding ropes from the cardboard boxes in the corner, and tied them to Ye Yibu and Huo Yibu.

"It might be a little tight, please bear with it a little, otherwise it's too dark inside so you can't see clearly."

The two Eevee didn't resist. They moved their bodies and didn't feel particularly uncomfortable.

Yinchuan asked his mobile phone Rotom to join the search queue. The ventilation ducts must be particularly complicated. The elves have to work separately most of the time, so it would be best to have multiple helpers.

Then Yinchuan stepped on the stool and removed the baffle of a vent. A lot of dust fell on his hair and clothes, but he didn't bother to take care of it and quickly let the three elves enter the pipe.

Ye Yibu searched from the 17th floor upwards, while Fire Yibu did the opposite. Rotom stayed on the current floor and waited, so that he could transmit information at any time.

Other teams were also assigned search tasks, some started from the first floor, and some started searching directly from the top floor. The small-sized Pokémon are very dexterous, and it is expected that the Pokémon in the ventilation ducts on each floor will be able to merge within half an hour!

At this moment, watching Yinchuan direct the elves to enter the pipe, Lu Yi suddenly remembered something and frowned unconsciously.

"Yinchuan, please try to dismantle the other exhaust vents."

Hearing this, Yinchuan, who was dusting off his shoulders, was stunned for a moment.

He blinked at Lu without knowing why, but then he acted without hesitation.

"it is good."

Yinchuan quickly moved the position of the stool and removed one baffle after another, while the solemn look on Lu Yi's face became more intense.

When he removed the last wind panel in the house, Lu Yi's eyebrows had already been twisted into hemp rope!

"The suspect does not seem to be a security guard in the control room."

Upon hearing this inference, Yinchuan and Muzi could probably understand his thinking.

"Brother Yi, do you think these baffles are too strong?"

"Yes." Lu nodded, "The prisoner is the type who has committed multiple crimes and committed crimes continuously. If the Rattata really entered the vent from the monitoring room, there should be a certain baffle that is particularly easy to remove. "

Hearing this, Yinchuan nodded in agreement. A lot of dust quickly slipped from his silver-white hair and almost drifted into his eyes.

"Ah sneeze——!"

Yinchuan was choked by the dust and sneezed. Suddenly, countless dust filled his body. Lu Yi quickly asked him to go to the bathroom and clean it to prevent his eyeballs from being infected with germs.

"Then what should we do now? Are we just waiting here?" Muzi asked Xiang Luyiyi as he looked at Yinchuan's leaving figure.

"The security staff should not only have this workroom, but also restrooms and offices around it. Let me go over there and take a look."

"Or remove the fender?"

"Ah."

With that said, Lu Yi turned off the handle and walked out directly.

Muzi was not idle either, asking Flying Mantis and Gotha Duck to help, while he stayed in front of the surveillance screen.

Inside the pipe, Yeib quickly searched various areas. During this period, it discovered that many pipeline forks were impassable and were blocked by a strange device.

That is the air duct regulating valve. When it is tightly closed, it means that the store connected to this pipe has not turned on the air conditioner, and cold air or hot air cannot be transported in.

Yeib informed Rotom of the discovery and asked him to pass it on to Lu Yi and the others, and then went to other floors.

Lu Yi attached great importance to the issue of the regulating valve because he had completely ignored it before.

What if Ratchet had gone to meet the trainer a long time ago, and the suspect happened to be dispatched by Miss Lijia at this time, and the air conditioner in that room was turned off before leaving...

Isn't Ratada perfectly hidden in a certain section of pipeline?

"Not a good feeling."

Lu Yi held a baffle in his hand and muttered to himself in disgrace.

About ten minutes later, he searched the surrounding areas where the security guards were working, and in the end he didn't find any problem with any of the vents.

But now that it is spring, the frequency of air conditioners used by the shops in the building has decreased. Many regulating valves in the pipelines are closed. If you want to go door-to-door to confirm, there is no time at all!

After rejoining his teammates in the control room, Lu Yi reported the progress to Mr. Dalin with some anxiety, and the latter also shared bad news with the three.

"According to the data registered at the Pokémon Center, none of the 25 security guards in the department store have bred Pokémon like Rattata."

After hearing this clue, Lu Yi and the others' heads seemed to explode, and they were immediately confused!

"Is it really an outsider who committed the crime??"

Lu Baibai was puzzled. All the known information clearly showed that the suspect was extremely familiar with the situation in the mall. Even the Rattada had not been caught for committing crimes many times!

Would an outsider know this much about the department store?

"Could it be an employee who resigned before?" Yinchuan looked at Lu Yi and asked.

But before Lu Yi could answer, Mr. Dalin added: "We also checked the old employees in the past, and they also did not breed Pokémon like Rattata.

The department store is a landmark building in Yuhong City. The internal management system is very strict. The security Pokémon equipped are all cultivated by the mall independently, so that the security guards recruited can work normally even if they are not trainers.

Shopping malls are asset-heavy units. For positions such as security guards responsible for people's life safety, the review is very strict. They must register their personal information before taking up the job. "

After hearing this, Yinchuan looked at Lu Yi blankly, as if he didn't know what to do.

But Mr. Dalin hasn’t finished speaking yet: “It’s hard to say yet about the identity of the suspect. Because it is assumed that he only recently tamed a Rattata and never took it to the Elf Center to register it. In our database It is impossible to update and synchronize.

In other words, old employees, current employees, outsiders, every situation is possible! "

Hearing this, Yinchuan showed a look of despair.

"Captain Lin, how can we investigate?"

Yinchuan's words speak to Muzi's heart. His straightforward character is sometimes a good substitute!

"Of course we can check." Dalin showed a confident smile in the video screen.

"Isn't there also Ratatouille?"
