MC "Bi*ch even if you are one-handed mime with a skin rash, you think I can beat you with that large level gap?"
No steep cliff now, we can see how this ends.
MC does make a good point: Why must old blood be repaid with fresh blood? Why must you be a bastard because someone was a bastard to you in the past? Does that make it right?
Guys, ya'know, when someone writes a really dumb villain, it makes it really easy for the MC to make "a snappy and accurate comeback".
There's nothing intelligent here, just generic low-hanging-fruit wuxia nonsense.
