Fei Yunlai's heart tightened instinctively as he perked up his ears.
This was the reason he no longer wanted to collaborate with Lin Rui.
The Earth Federation had far too much advanced technology, and even if you could perfectly erase all traces, the Security Bureau and the powers of the Federation could still find them through various means.
Big data extrapolation was one of these methods.
This method couldn't convict them, but what do crime gangs need evidence for? As long as they find the person, they would retaliate.
His and Lin Rui's characteristics were also very distinctive, one at level 4 and the other at level 7.
Others, by studying their martial arts characteristics and some minor clues, could figure out who they were.
Fei Yunlai specifically glanced at Lin Rui, who was still eating and drinking as if he wasn't worried at all.
This guy's psychological quality was truly extraordinary.
