Chu Ren, who had just taken off his military uniform, jumped into the river to save a drowning child. When he opened his eyes again, he became a hungry bandit leader in the troubled times of the Warring States Period. There are less than a hundred people in the village, and slash-and-burn farming is not even considered, and all of his men are sallow and thin. Seeing that he was about to sink into obscurity in this cannibalistic world, the military concepts and production knowledge that spanned two thousand years suddenly began to heat up in his mind. While others are still relying on brute force to grab food, Chu Ren has used modern thinking to train an elite soldier who can obey orders and prohibitions. From being the leader of a stronghold to becoming the king of the Earth-Cracker, who would have thought that the man who stirred up the turmoil in the Seven Kingdoms was originally just a bandit who wanted to have enough to eat?
