One Punch: I, KING, Am Really the Strongest on the Face of the Earth

[Invincible flow + cool writing + game system + beating up weirdos + making up for regrets] Traveling through time and becoming the S-class hero KING, facing a life and death crisis at the beginning? Don't panic, the title known as "The Strongest Man on Earth" is no longer a misunderstanding this time, but a fact! KING discovered that his heart had mutated, and every violent beat (Emperor Engine) would bring an exponential increase in strength to his body! As long as your heart beats fast enough, even the gods will fuck you up! [Emperor Engine·First Gear]: Heartbeat 120, normal punch, the building collapses! [Emperor Engine·Second Gear]: Heart rate 180, muscle density compression, ignoring Boros Star Cannon! [Emperor Engine·Overlimit]: The heartbeat is 300+, which is a power that exceeds the limiter. Even the bald man was dumbfounded! Elder Centipede? It's just an elite monster with a longer health bar, with a critical hit of 999! Association of weirdos? That's a great copy of the experience! Boros? Sorry, your Star-Breaking Roar Cannon was perfectly defended by my "Block" skill. Hungry wolf? Boy, your punches are too slow. Look clearly, this is the real combo! Genos: "As expected of Mr. KING, I can't see his movements at all!" Atomic Samurai: "It turns out that KING has never drawn his sword because we are not worthy of being his opponent..." Saitama: "Hey, KING, don't steal my monster next time, and the game cartridge you borrowed last time hasn't been returned to me yet!" Weird people all over the world trembled when the Imperial engine roared to life again. This time, it's not just luck, this is real - god-level power!
