Comments of chapter undefined of Xianxia: My Disciples are Insane!

what's the point of him being here? injury? doesn't he have sign system? why not use it? because of injury he injured his head? where's the benefit? isn't just a filler arc? I've read something like this but the quality cannot even compare with this novel, if I ever compare the"Top Tier Providence, Secretly Cultivate for a Thousand Years" and "master is not mortal right" with this novel it would make them a masterpiece. so I'm dropping here.

solo falta la correa que diga esclavo y ponérsela, todo lo que le piden lo hace le MC, es estúpido?.
