The thing in Lu Yu's hand, similar to a USB drive, is a wireless signal transmission medium. With this medium, one can effortlessly hack into any computer, making it an absolute tool for espionage.
The reason Lu Yu put such effort into roping in Zhou Wenyuan was to leverage his conflict with Zhou Xianrong, bringing this device into the Zhou family's surveillance room.
According to the report from the scout team sent earlier, the surveillance room is no ordinary place.
The entire Zhou family is under the surveillance coverage, and the surveillance room is also the source of all the computer information in the Zhou family. If one could successfully hack into the surveillance room, then they could invade any computer within the Zhou family!
At that time, all the Zhou family's information would be under Lu Yu's control, and even the bank accounts could be manipulated by him at will!
By then, attacking the Zhou family would be as easy as turning over one's hand!
