Born with a Chaos Body, I Sign In and Crush Every Enemy Under Heaven

[Decisive and ruthless + invincible + steamrolls all the way + villains + competition among prodigies.] Jiang Chen transmigrates to the Three Thousand Dao Provinces and becomes the Imperial Son of the imperial Jiang Clan. A glorious age is in full bloom, with countless races and prodigies vying for supremacy. Jiang Chen awakens a System and signs in for a Chaotic Body while still in the womb. And so, an invincible monster emerges out of nowhere. You say you're from an Ancient Sacred Land, with an invincible physique? No. I throw one punch, so why are you running? You say you're the chosen protagonist, blessed by the fortune of the Heavenly Dao? Sorry, the Heavenly Dao is nothing but my lackey. You say you're a goddess from the Divine Realm, peerless in grace and beauty, unrivaled under heaven? Then you shouldn't cry for too long after I punch you, right? Years later, Jiang Chen sits dressed in white above the River of Time, with the myriad Dao rising and falling beneath his feet. Wait, how did I become invincible without even trying?
