The Peddler Between Two Worlds: Selling Scrap to the Cultivation World

Zhou Yan runs a nearly bankrupt hardware and electrical store, with little money in the account but a warehouse full of industrial surplus goods bought cheaply in the past, now destined for clearance sales. Until one day, he pushes open a rusty old iron door in the warehouse. Behind the door lies a cultivation world filled with sects and mines. Old bearings that can't sell in the modern world become valuable there, keeping mines running and making mine owners willing to pay real gold and silver; inconspicuous steel cables, seals, and standard parts also gain entirely different worth. Meanwhile, spiritual ore waste and beast byproducts unwanted in the cultivation world can become another business when brought back to the modern world. Starting with a box of old bearings and a small warehouse, Zhou Yan builds workshops, raises a merchant caravan, and paves trade routes, slowly turning an accidental price difference into a supply chain spanning two worlds. While others vie for immortal destiny, Zhou Yan calculates costs, delivery, and profit. — Description from novelcodex.org
