My Trading Partner Comes from a Parallel World

Yang Xingyue never imagined that the dusty bronze compass in the attic of her family’s old house was a trading hub connecting parallel worlds. One accidental touch, and the compass suddenly glowed. She received a plea for help from the “Spirit Plant Plane”: they would trade thousand-year-old spirit liquid for modern antibiotics capable of curing a disease afflicting their exotic plants.

From then on, her life went completely off the rails. She traded instant noodles for the cores of ancient demon beasts, ordinary glass marbles for strange ores that could control wind, and even used a book called The Complete Guide to Plant Care to secure a long-term partnership with an alchemist from a magical world. Through these trades, she met companions from parallel worlds, each with a very different personality: a sharp-tongued but dependable young master of spirit plants, an adorably naive magic apprentice, and a cool, aloof researcher with technology from the future.

She thought it was merely a mutually beneficial business spanning time and space. But as the trading went on, Yang Xingyue discovered hidden connections among the different planes, and a secret about her family’s bloodline lurking behind the compass. When crises began spreading across the parallel worlds, the trade list in her hands gradually became the key to saving all realms. This cross-time-and-space trading venture, which began by accident, ultimately brought her friendship and growth as she traveled through countless worlds, while unlocking an extraordinary life of her own.
