Those who were tailing Fang Bai had no idea that he was using his Divine Sense to conduct a "dragnet-style" search throughout the city, looking for traces of the "Wrathful Beauties" assassin.
Fang Bai was certain that the series of attacks targeting members of various meta-human organizations must have been jointly planned and carried out by many assassins of the "Wrathful Beauties."
That is to say, in this city, there were definitely more than just the woman in black who was an assassin from "Wrathful Beauties."
Fang Bai believed that by using his Divine Sense to perform such a "dragnet-style" search, no matter where the "Wrathful Beauties" assassins hid, they would have nowhere to escape.
Unless the "Wrathful Beauties" assassins each had an artifact like the jade thumb ring worn by the woman in black, capable of hiding their presence and rendering Fang Bai unable to sense them.
