Dual-World: Bread for Maid Swap

After the college entrance exam, Lin Chen unexpectedly awakens a dual-world system, allowing him to travel between the modern city and the fantasy realm. He trades bread to obtain the fantasy maid Yang Xiu and ventures into the fantasy world armed with modern weaponry, bringing back wild ginseng and jade raw stones from the fantasy realm to sell in the city and become wealthy. He meets the Qin family siblings, helping them resolve crises with modern medicine and supplies, engaging in transactions with the Qin family over salt and spiritual herbs, and is even matched with Qin Yuling as a spiritual partner. Through shuttling between the two worlds, he achieves a rags-to-riches transformation and starts a unique life.
