Water Margin: Born with the Strength of a Tyrant from the Start

[No System] + [Invincible Protagonist] In the late Northern Song, the Flower Stone Gang brings misery; the outlaws of Water Margin are down to their last stand. Bandits in the mountains are too weak to make their mark; four rebel kings rise in the east, west, north, and south. While contemplating life on Tiantai Mountain, he is struck by lightning and reincarnated in the late Northern Song. War and chaos are just around the corner. The children around him are all destined to die young, and the men are crude, hulking brutes. How is he supposed to find a way to survive and make a name for himself among the lords? He clenches his fists. Wait, is my strength absurdly powerful? I’m like the Overlord reborn! Heh heh, Song Jiang, take one of my punches!
