The middle-aged man chose Target Number Two for a reason: while Zhou Qingfeng was following his grandfather around the base, he accidentally overheard a researcher from Qingshan Base complaining in the restroom that China Power Investment Corporation's construction did not follow their instructions, wasting nearly half a month repairing the wrong place.
The partially built test site had not yet been decided what to do with it and remained in a state of abandoned wasteland. Birds even attempted to nest there.
This indicated that the abandoned test site was not strictly guarded and seemed to provide a path into the interior of Qingshan Base, representing a vulnerable point that could be breached.
The middle-aged man did not believe it would be easy to sneak into the base through this gap, but he thought it might be possible to find a signal line or something to intercept and eavesdrop on communications.
