Zhang Zi'an first came to the company that lost the import watch and used the access card provided by the fly to open the floor-to-ceiling glass door.

Lao Cha looked at the access control system carefully and asked, "Zi'an, can only this small card open the door?"

"It should be." Zhang Zi'an patted the access card in his hand, "but it's hard to say, because this card can be copied privately by people with ulterior motives. Through some uncomplicated technologies, as long as there is an original card, you can even copy a copy of the same function in a few seconds, so don't have too high expectations."

Lao Cha nodded thoughtfully, "I'm wondering, even if the cats stole things, how did they run away? Is someone opening the door for them?"

"It's very likely." Zhang Zian admitted that he thought from the beginning that someone was manipulating the cats behind the scenes, perhaps a real cat tamer.

He pulled the door and asked Xinghai, Lao Cha and Fina to go in first and then go in again by himself.

There are two companies on the 5th floor. The company that lost its watch is called Hongye Trading, which is a small and medium-sized enterprise focusing on the foreign trade of clothing.

Zhang Zian recalled the content in the video and quickly found the office where he lost his watch.

When he opened the door lock and pushed the door in, he saw Liu Miao's desk at a glance, or the desk that used to belong to Liu Miao. Currently, the name tag on the desk has been changed to someone else.

The layout of the office is no different from other office buildings. The desks connected into one piece are arranged in an orderly manner. Each desk is placed with one or two monitors, and less important documents are scattered on the table. Through some debris on the desktop, you can roughly tell whether the owner of the desk is a male or female. The scene also gives Zhang Zi'an a very familiar feeling.

"Zi'an, I feel..." Lao Cha said halfway through his words, and he and Fina looked up almost at the same time.

Zhang Zian didn't understand why, so he followed them to look up.

Above my head is a metal ventilation duct that crosses the entire office.

"What's wrong?" he asked in wonder.

"Shut up!" Fina's ears turned like a radar antenna, aiming at the ventilation duct.

"Zi'an, there seems to be movement there." Lao Cha whispered.

"What's the noise?" Zhang Zian also lowered his voice. He widened his eyes and looked at the ventilation duct, but he heard nothing.

Lao Cha shook his head, "Now there is no more, it seems that something is jumping quickly, very low, maybe..."

"It's the cat tribe." Fina said with a cold face, "I didn't expect that there are really scum who dared to do evil and tarnished the reputation of the cat tribe!"

So say...

Zhang Zi'an carefully observed the ventilation duct, "It means that those cats who steal things are in and out of the ventilation duct?"

"It's roughly impossible to be wrong." Lao Cha said with considerable confidence.

"No wonder we can't catch them all the time, so that's it." Zhang Zi'an's confidence suddenly became stronger, "Then we can find the prisoner's location by following the clues."

"We need to find out how those cats got in first." Lao Cha reminded him.

Zhang Zian said that it is impossible for those cats to appear out of thin air in the ventilation duct. There must be an entrance and exit so that they can enter and exit freely. Generally speaking, there is a mesh fence in front of the air outlet of the ventilation duct. The cat may be able to push the fence to jump out, but it is definitely impossible to restore the fence to its original state when it leaves.

"Meow! Xinghai can go in!" Xinghai suddenly said.

Zhang Zian was stunned and then understood the meaning of Xinghai. It was to enter the pipeline in a quantum state and then return to normal in the pipeline. This was a feasible and simple method, but he was a little worried.

"Xinghai, is there no problem?" He squatted down and asked Xinghai.

"No problem! Hide and seek! Hide and seek! Xinghai never loses when playing hide and seek!" Xinghai said enthusiastically, and then he seemed to think of something, "Meow~ I only lost to Zi'an once!"

Zhang Zian looked at Xinghai's serious face, then looked at the cold metal pipes above his head, and was puzzled whether to let Xinghai try it out.

"Xinghai wants help!" Xinghai said quite persistently, "Xinghai is a good boy! Those cats are bad boys!"

"Zi'an, according to Lao I'm not afraid of this trip." Lao Cha looked at him with encouragement.

He nodded, "Okay, Xinghai, just go and try it. When you feel that there is danger, come back immediately."

"Xinghai knows!" Xinghai was eager to try it out in the ventilation duct.

"Also, you don't need to stop them in Xinghai. Just follow them and see where they ran." Zhang Zi'an said patiently, "Our purpose is to capture the master messenger behind the scenes."

"Okay, that star sea is here!"

Star Sea stared at the ventilation duct.

Zhang Zian stared at it with some concern, knowing that it would disappear in an instant, and then it would appear inside the ventilation duct the next moment.

However, after a moment of unexpected events, the sea of ​​Xinghai remained unmoved.

"Huh? Why can't Xinghai get in?" Xinghai raised one of his front paws, waved it gently in front of his eyes, and said in confusion.

Fina and Lao Cha were stunned.

Zhang Zian was puzzled and asked, "Xinghai, do you feel uncomfortable?"

"No, Xinghai is very good." Xinghai's eyes were confused, "but Xinghai just couldn't move."

Zhang Zi'an looked at Lao Cha with help, "Mr. Tea, do you know what's going on?"

Lao Cha shook his head in confusion, "Zi'an, you seem to have said that Xinghai is a very special child. Even if he uses the most advanced modern technology, he may not be able to capture his figure... Isn't he very much about modern technology..." It looked at the camera in the corner of the ceiling, "Is that thing a fool?"

Zhang Zi'an felt a little moved and looked over with Lao Cha.

From the appearance alone, it is impossible to tell whether the camera is still working.

Is it an unexpected observer?

He picked up the intercom, pressed the call button, and said, "Is it smaller than now? Is it smaller than now? It's over."

After two or three seconds, Yu Fei's voice came from the walkie-talkie: "Received. Is it Mr. Zhang? Is there anything I need my help? It's over."

Zhang Zian: "I want to ask, is the camera on the 5th floor now on or off?"

About four or five seconds passed this time.

Yu Fei: "It's closed."

"It's been closed and has not been turned on. If Mr. Zhang doesn't believe it, you can go down and take a look. If it is turned on, the surveillance system will automatically record the video." Hearing that Zhang Zi'an's tone was a little wrong, he added.

Zhang Zian heard that he didn't seem to be lying, so he raised the intercom again: "I understand, please leave it off, please keep the surveillance monitor."

Yu Fei: "Does Mr. Zhang need help?"

Zhang Zian: "No need for the time being. I will tell you when I need it, it's over."

He put down the walkie-talkie and turned around again, only to find that the sea of ​​stars was missing.
Chapter completed!
