Lin Yi, naturally, wasn’t expecting Cihua to just let him go- the jade on his neck started signalling him soon after he drove out.
Lin Yi smiled faintly- as expected, a black SUV started following him a while later. It had just entered his field of vision, quite some distance away, too- but Lin Yi had received a warning from the jade beforehand, and was absolutely certain that the vehicle was hostile.
While it wasn’t impossible for him to have determined the nature of the follower, he’d still have to have spent a certain amount of time for that. This golden finger of his, however, saved him that precious time. It wasn’t too useful in the cities, but a mere one second earlier or later in detecting the enemy in a warzone made all the difference between life and death.
