That was kind of lazily written chapter. Family was never mentioned (I believe it was said that he was orphan) yet instantly he has loving one. Police instantly tells criminals, who ratted them out. Cripple is basically unconscious and to everyone it seems that he failed cultivating, yet his father kills him and goes after MC as if he is responsible (he is but no one knows that).
I mean, only three things happened in this chapter and all of them were horribly written. You need to have a limit to this horribleness.
