Mortal: Upgrading from Flowing Cloud Sword to Azure Bamboo Cloudswarm Swords

A fanfiction tale set in the world of A Record of a Mortal's Journey to Immortality. Lu Chen transmigrates into this cultivation realm, but unlike the fabled protagonist, he does not possess the heaven-defying small green bottle. Instead, he stumbles upon an equally miraculous treasure—the Mysterious Colorful Stone. This stone grants him a singular ability: any magical tool, material, treasure, or even higher-grade artifact can be subjected to a single upgrade enhancement. By continuously upgrading and trading his enhanced items for resources while honing his crafting skills, Lu Chen carves out his own path to wealth and immortality. Years later, the two cultivators who were once cast aside as disposable pawns by Yellow Maple Valley s쳮d in forming their Nascent Souls beyond the sect's borders. They reunite at Falling Cloud Sect and join forces once again. The unremarkable Daoist Han regards his Azure Bamboo Cloudswarm Swords with pleasant surprise as they are refined into a state brimming with spiritual radiance, their power now far surpassing their original form. "Brother Lu, I never imagined your unique refining and pattern-ascension technique could be so miraculous—enhancing them without adding a single material, yet matching the quality of a Geng Jin treasure. It seems I owe you a favor," Han Li remarks. "By the way, I have seventy-one more swords here that I must trouble you with as well." Lu Chen, possessor of the Mysterious Colorful Stone, falls silent. "...Then I shall rely on Brother Han to procure the large quantities of Geng Jin I require," he replies. Han Li, possessor of the small green bottle, can only respond with a puzzled silence of his own.
