Zhou Ye, a modern hardware engineer, is betrayed by his fiancée and business partner, who join forces to seize his company and leave him burdened with enormous debts. On the brink of death, he awakens the Myriad Treasury in the palm of his hand and travels to the fictional late Da Sheng dynasty. With natural disasters and bandits ravaging the land, he uses modern supplies to gather refugees, build fortified settlements, and establish rules. He fights mountain bandits and takes down corrupt officials, transforming a desolate village into a haven amid the chaos. Summoned to the capital, he becomes entangled in a political struggle between eunuchs and regional princes, only to encounter another transmigrator possessing the same miraculous power. One treasury consumes its user's lifespan with every transaction, while the other has a limited storage capacity. When the two treasuries clash, who will emerge victorious? Zhou Ye seeks no imperial throne; he only wishes to protect the countless people who have chosen to follow him.
