I'll admit... it took me way to long to realise that the guy with two missing fingers is not the light something gang that the Round Kid gave to Yang Kai in compensation... but just a character design identity mistake on the Manhua's behalf. He's supposed to be that naan bread young lord who Yand Kai had cut of his fingers. But since the proximal phalanx is still present... it should be quite possible for a society with cultivation and magic means to design a suitable prosthetic, right?
