Core setting: Lin Feng, a modern social animal, accidentally traveled to the famine-torn Xuanwu Continent and became a starving man on the verge of death on the road to exile. In a desperate situation, he bound to the "Dual Boundary Warehouse System" to connect to 1983, when supplies were relatively scarce but initially stable.
I took my warehouse in 1983 through troubled times and barren years. I exchanged compressed biscuits for daggers, used antibiotics to save lives, and silently farmed and advanced science and technology in the era of exchanging food for food. Until the world was in chaos, and a torrent of steel opened up in my warehouse.
