At the age of fourteen, his soul passed through a farmhouse in the Northern Song Dynasty and died at the age of a hundred.
No fighting for hegemony, no rebellion, no black technology. He just used the stupidest method - taking one more island, cultivating one more acre of wasteland, saving one more stone of food, and saving one more person - before the dynasty overthrew, he built an archipelago in the southeastern sea that could accommodate 100,000 Han people.
Sixty years of dormancy, one hundred years of planning. During the Jingkang Incident, everyone was fleeing. He had already prepared ships, food, land, and orderly human rooms on the islands.
The archipelago preserves the Han people, and they will have no regrets in this life.
