Wang Han, a modern wilderness survival expert, was accidentally reborn in a parallel world similar to the late Qing Dynasty and the early Republic of China - the snowfield outside the pass. He became the bandit leader "Wang Dahu" who was about to starve to death, with only three crooked melons and jujubes under his command. In order to survive, he relied on his survival knowledge and the unexpectedly activated [Life Teaching System] to transform a dilapidated village into a paradise. He used Northeastern dialect and modern thinking to lead his brothers to farm, build infrastructure, and open trade routes, making countless jokes. As the village grew, he was forced to get involved in struggles with local warlords, Czarist Russian forces, and the Japanese. The simple desire in the early stage "to have a good meal" gradually sublimated into the national justice of "protecting my homeland and protecting my compatriots". In the end, Wang Dahu was no longer the "beard" who occupied the mountain and became the king, but became a hero who enlightened the people's wisdom, promoted industry, drove out foreign invaders, and emancipated the mind, lighting the torch to a new era for this black land.
