Lin Dao transmigrates to a new world but discovers his browser history and a mysterious spacetime trading ability have followed him. Working a dead-end warehouse job in modern Haicheng after being betrayed by his girlfriend and sidelined by a returning CEO, he vows revenge. In a parallel ancient realm resembling the chaotic Yonghe era, he meets Jin Lian and other women fleeing Hu Cavalry sent by the Imperial Court to abduct females for the Heavenly King's harem.

Using modern goods like compressed biscuits and improvised weapons such as Molotov cocktails and a motorized tricycle, Lin Dao establishes himself as a protector and merchant, trading across dimensions for profit while building a loyal following. He balances his mundane logistics job with cross-time commerce, accumulating resources and power to one day return and make his enemies repay every grudge a hundredfold.
