I'm Really a Cultivation Middleman

The Holy Son of the Dayan Sect wants to cultivate the Great Dao Immortal Body, but he lacks a Great Dao Fruit. The young master of the Heavenly Sword Sect wants to forge a Heart Sword, but has yet to find auxiliary materials that match his state of mind. The Star Pavilion wants to build a Star-Gazing Tower to peer into fate, and has spent nearly a century searching for a Fate Star Stone. The Imperial Daughter of the Di Clan has hit a bottleneck and wants to undergo a tribulation of love to break her shackles. The Zhang family patriarch is nearing the end of his life, and the family is on the brink of collapse. Unwilling to accept his fate, he seeks the Waters of Three Lives to be reborn from ruin. Zhang Fan, a top agent for the Bei family, ventures alone into a fantasy world. He has no world-shaking cultivation, no peerless bloodline or spiritual root, and is thoroughly ordinary in every way. Yet he doesn't panic in the slightest. In a world where money comes first, he profits from price differences; in a world where strength reigns supreme, he profits from cultivation gaps! The Zhang family patriarch has a Great Dao Fruit. The Star Pavilion has the auxiliary materials that suit the Heavenly Sword Sect young master's state of mind. The Dayan Sect has found a perilous place containing a Fate Star Stone. And the Waters of Three Lives were bestowed upon the Imperial Daughter by the Di Clan patriarch, and have hung around her neck for years. So the Dayan Sect's Holy Son obtains a Great Dao Fruit, but only manages to cultivate the Great Dao Body. The Heavenly Sword Sect's young master forges a Heart Sword, yet still feels his state of mind is incomplete. The Star Pavilion builds its Star-Gazing Tower, but can only glimpse fate at the cost of losing its own fortune. The Zhang family patriarch is reborn from ruin, but somehow can no longer grow up. Feeling his physique, state of mind, cultivation, and fortune surge, Zhang Fan knows that actual cultivation is out of the question. The only way to survive in this dangerous world is to work as a middleman and pocket the difference. “Zhang Fan! If you really don't want to marry into my family, I can come with you instead!” Looking at the Imperial Daughter, who had chased him for three thousand li, Zhang Fan cursed inwardly. “We're both lusting after each other. Can't we just keep things mutually casual and peaceful?”
