[Reborn] My Foolish Disciple

When Mo Guiling transmigrated into a novel as its biggest BOSS, he was against it at first. But fate could not be defied. The once exemplary young man eventually turned evil and became a Demon Lord who killed without batting an eye. And then... He died. ╮(─▽─)╭ But instead of having his soul vanish, he was reborn after his death, which was quite unexpected. Although he hadn't chosen to be reborn, now that he was, what should he do? Kill the protagonist while he was still a little kid? Well, that's what any normal person would do. But Mo Guiling had been evil for a thousand years. He was a hundred thousand miles from normal. What even was morality? Could you eat it? Mo Guiling: Kill that little brat? Don't make me laugh. Life's already this boring. If I kill the only worthy opponent I'll ever have, I might as well just die. But this kid's way too weak right now, isn't he? (;￢_￢)?? So Mo Guiling, the Demon Lord, took Ye Liuchen, who was still a little kid, as his disciple after being reborn~︿(￣︶￣)
