In a World of Martial Might, I Fight Whenever I’m Not Happy!

[High-martial world + power fantasy + no female lead + fast-paced + ruthless protagonist] “Lin Ye, I’ve got a genius backing me up! Even if you’re pissed off, keep it to yourself… You beat me up, and you beat up that genius too?!” “Lin Ye, this monster may be a menace, but it’s powerful. Lots of people can’t stand it, but… you just killed it?!” “Lin Ye, you’re up against a god! Even if you’re furious, you have to hold back, or else… You actually beat up the god?!” … After transmigrating to Blue Star, where martial arts reign supreme, Lin Ye awakens the Get-It-Done-When-I’m-Pissed System. You’ve made him mad? He’ll come after you, no questions asked! The top prodigies: “Whatever you do, don’t make Lin Ye mad. Otherwise, you’re on your own.” The major factions: “When Lin Ye glares at you in a foul mood, it’s best to crouch down with your hands over your head. You might take fewer hits that way.” The gods: “In front of everyone else, I’m untouchable and hit hard. In front of Lin Ye, I’m meek and cautious!” … Lin Ye: “A god? If you piss me off, even a god is going down!”
