Starting the Apocalypse, I Used the Simulator to Get a BUG

(Pitfall avoidance guide: This book is not in a dark style.) [Global Flood] + [Super Power] + [Hot Blood] + [Decisive Killing] + [Build Power] Awakening life simulator days before the end of the world. The end of the world is coming, and the world is swallowed up by floods - monsters are rampant and humanity is wiped out. The protagonist rises in troubled times, kills his enemies with the sword, builds great achievements, recruits powerful generals, and kills all the leaders of various tribes. Even the zombie king trembles. "The weakest human race has such a freak." "This boy is really the doom of my zombie clan!" (The introduction is weak, please read the text)
