Trading Across Worlds: Did You Just Buy the Trader on the Other Side?

[Interdimensional Trading] + [The Myriad Worlds] + [Spiritual Qi Revival in the Main World] + [Invincible] + [Exploring Other Worlds] After transmigrating to a parallel world on the verge of spiritual qi revival, he gains the authority to trade between planes and becomes an honorable agent for a basic-material plane. He trades across the heavens and the Myriad Worlds, making a living from deals that cost him nothing. He trades history textbooks to the Great Sage Teacher in exchange for the art of summoning soldiers from beans. He buys a million stunning elf slaves wholesale in a high-magic world. He sells classical Chinese poetry and the teachings of the Hundred Schools of Thought to a Confucian world. He purchases a “System” from a divine civilization that has reached its peak. Compared to all that, spiritual qi revival in the main world, the emergence of strange creatures, and even an alien invasion hardly seem like a big deal anymore. Dear trader, are you about to suffer a Dark Forest strike over there? Hey, we've got some advanced technology that can upload your consciousness, called the Ten Thousand Souls... Human Emperor Banner. Care to take a look? Before long, the infinite multiverse has become Fang Baiyu's playground.
