The next day, an unfamiliar number called. Relying on his intuition, Li Yifei immediately knew it must be from the other party. After nodding to the few people in the room, he finally answered the phone.
The room was filled with electronic equipment. If anyone else saw this scene, they would surely suspect it was some critical military department because even the average technical division of the Public Security Bureau or ordinary military equipment wouldn't be this advanced.
For most, getting their hands on equipment like this, let alone even seeing them, would be a long shot. But given Li Yifei's extensive connections over the years, especially in this particular field, acquiring such tools was not difficult.
As for the specialized personnel, Li Yifei had also made early arrangements to recruit them. This place could be considered the core of the entire Li family estate, with most of the electronic surveillance equipment located here.
