This secret passage, hidden so cleverly, is the key to Zhang Xiaoyun's disappearance and reappearance.

This discovery made Liu Juan even more convinced that there were secret activities inside the food factory that were unknown to the public, and that Zhang Xiaoyun was very likely involved.

She quickly drew a simple diagram of the office building in her mind.

The basement where Zhang Xiaoyun is now is the ceiling of the R&D department’s office. If that’s the case, does that mean that the people in this office have any relationship with Zhang Xiaoyun?

Just now, Suihe had created a WeChat group command. Besides Suihe, Liu Juan, Chunsheng, and four other comrades were in the group. Liu Juan didn't recognize the other three, but she knew only one, whose WeChat name was "Ai Shui Shui," as Li Yichen, Jiang's vice president. His wife's name was Jiang Shui Shui, so the WeChat name couldn't be wrong.

Chairman Jiang is a father-in-law who loves to sleep.

After clarifying the relationships between the characters, Liu Juan began to talk about her recent discovery in the group and also sent screenshots of the thermal imaging video to the group.

Suihe reacted very quickly and immediately asked Chunsheng who was in the office downstairs. Liu Juan had just thought of this and felt that the person downstairs must also have problems, otherwise it wouldn't be such a coincidence.

Also, the decoration team must be checked.

It stands to reason that the building was built by Jiang Construction, not by anyone else. However, the renovations were not necessarily the case, and any problems that arose during the renovations would have to be addressed by the on-site personnel at the time, which was not reflected in the contract.

She posted this idea in the group, and one of the three strangers replied, saying she had received it. Within ten minutes, the construction and renovation contract for the office building was circulated in the group.

Not only the two contracts, but also the detailed information about the renovation company had been clearly laid out. The efficiency was astonishing. Liu Juan secretly admired this kind of teamwork, which undoubtedly provided a great help in solving the problem.

She carefully studied the renovation contract and found many unclear clauses. Furthermore, the renovation company seemed to have close ties with the Jiang Group. This made her think that perhaps this elaborate surveillance operation had been quietly planned from the very beginning.

The most frustrating thing is that the renovation was outsourced, meaning a third party was involved, which makes the investigation even more difficult. Now is not the critical moment to investigate why the third party appeared; the third party must be found.

The contract shows that the contract for this building was signed 8 years ago. This building was newly built by Jiang's Construction. Logically, Jiang's construction team should not have outsourced the decoration at that time, so this matter must be investigated as soon as possible to see what problems occurred at that time that led to outsourcing such an important project.

Liu Juan spoke again, pointing out the potential connection between the decoration company and the Jiang Group, and suggested that an immediate investigation be conducted on the relevant personnel of the decoration company, while strengthening the monitoring of the relevant personnel of the Jiang Construction Group.

Li Yichen agreed with her proposal. Stranger No. 2 in the group replied, "Got it." Then he disappeared.

At this time, Liu Juan's eyes fell on the thermal imaging screenshot again. She wanted to go to the R&D department herself to see if she could find more clues there.

I voiced my thoughts in the group chat, but Suiyou disagreed. She argued that if employees from her finance department went to R&D without any business, it would arouse suspicion. Then, Suiyou called out stranger number three from the group, claiming he was responsible for the matter. Stranger number three replied, "Got it," and then disappeared.
