"If you really feel guilty, then kill ten times or even a hundred times more of the ink disciples!"
What the fuck, Yang Kai!? Get out of here, moron. Ink disciples are your fellow human race, who were inked and aren't anymore in control of their actions. Bai Yi was an ink disciple. Now, after being cured, she feels so bad about her actions as an ink disciple, despite not having control over her own actions, that she wants to die. And this little fucker Yang Kai tells her to go out and slaughter other ink disciples to make herself feel better? Jesus Christ, dude. This is the MC of the story? What a joke.
