Poor Talent? One Day of My Life Is Exchanged for Ten Years of Cultivation!

[High martial arts + krypton life + decisive killing + fast pace + invincible horizontal push] F-level talent, recognized as trash. They said I wouldn't live past twenty. Until I activate the krypton life system—— Other people's lives are calculated in years; my life is calculated in seconds. I burn for one day in exchange for ten years of hard work for them. Three days later, the school bully knelt in the pile of broken bones and begged me: "Madman! How many years will it take for you to be enough?!" I said, "A guy like you is only worth three seconds to me." Three months later, the No. 1 Player in the province was trembling at my feet: "How much life do you have left?!" I bent down and whispered in his ear: "Not much, but enough to kill you all." Three years later, the headquarters of the Global Gaowu Alliance. The charges on the S-class wanted poster read: [Lifespan unknown, extremely dangerous, do not encounter alone] The whole world is betting on when I will die. Some say there are three years left, some say there are only three days left. Just now, I single-handedly destroyed their headquarters. Before he died, the president screamed: "When the hell are you going to kill?!" I looked at the collapsed city, wiped the blood from the corner of my mouth, and smiled: "Kill until no one dares to ask when I will die."
