I just want to kill you all, or be killed by you all.

[Exhilarating combat + decisive killing + too lazy to talk + one demon after another]
I am a deranged psychopath obsessed with killing, but to avoid becoming an enemy of the righteous and standing on the opposite side of the world, there is only one path—
Black eat black!
……
Demonic cultivator: "What's wrong with demonic cultivators? Do they all deserve to die? How are you any better than them, killing so recklessly?!"
Me: "I'm too lazy to reason with you. You're not worthy to listen. Go talk to my Heaven and Earth Justice Human Emperor Sword! Remember! Once a demonic cultivator, always a demonic cultivator!"
……
Me: "They suffered from acute metal poisoning, it has nothing to do with me. What do you mean they were hacked to death? Believe me or not, I can give you acute metal poisoning too!"
……
"Sorry, I thought it was a horde of demonic beasts. My flying sword couldn't stop in time. Ouch, your blood mist blinded me; that's a blind spot! Seriously, who walks around in the Demon Realm like that? We're having a tough time too, you know. What a mess this is! Hmph! Go tell my flying sword then! We're all trying our best to survive... huh??? I've been trying so hard, how are you still alive? Flying sword, turn around and strike again!"
"I don't know! They were yelling 'This is too much!' and then they rushed over and stuck the flying sword to it. I couldn't shake it off."
