Divine Swap: My Journey to Immortality

Harrison Yale hands over a pair of underwear and gets back a pill made in the immortal world. He got into the WeChat group by accident. The other members are on the immortal side, and they will take ordinary things from the human world, a bag, underwear and the like, and send back medicine, gold, pills and martial arts manuals in return. Harrison delivers food for a living. Once the trades start, the gold keeps coming and so do the pills. He picks up medical skill and martial technique from what the immortals send him, and before long he is richer than the conglomerate families, and the people who set themselves against him get crushed. He saves the life of a woman who runs a conglomerate, and the two of them begin a romance.
