I Have a Hall of Heroes in the Ancient World

… The Hall of Heroes, as the name suggests, all beings who had great brilliance during their lifetime and later left a mark on the world can enter it and become immortal heroic spirits! Traveling back in time and becoming a native in the early prehistoric times, someone faced with big bosses competing for merit in the sky, but he had to do something like "reach the battlefield in thirty seconds and start crushing them", and suddenly his head was as big as ten.
