Ye Fan laughed: "Sister Xu, really, it's nothing. If you don't believe me, go and see for yourself. The four thugs on the rooftop have already been dealt with by me."
"You alone against four? Do you really think you're Superman? Don't you try to trick me, if I go in and... my son dies, you're responsible!" Sister Xu cautiously took her gun and went to the rooftop, and finally verified that the four thugs on the rooftop had been shot dead, and only then did she breathe a sigh of relief, as her phone rang.
"Director Li, I'm up here... the thugs are dead, you can send colleagues up..."
Sister Xu was on the other side of the phone, while Ye Fan was observing the situation in the corridor, trying to comprehend why there would be thugs in this rather old-looking residential building.
