Reborn as a Dragon, Transformed into a Dragon Through Trade

[Decisive in killing + the protagonist is both good and evil + not the Holy Mother + the protagonist is a monster + evolution] Long Yi was sent to the world of cultivation called "Qingjie" because of his performance as a truck driver. He traveled through time to an ice dragon who was besieged by monks and was on the verge of death. When Long Yi wanted to experience time travel again, he was bound to the "God-level Trading System". As long as he completed transactions recognized by the system, he could gradually become stronger and evolve into a dragon. From then on, a well-known demon "profiteer" appeared in the Qingjie. "What? You want to buy my mount?" "What? Do you even have a chance to become emperor?" "What? You actually make loan sharks?" "What? I am the demon lord who makes the world fear nightmares, and you actually want to make a deal with me?" In doing business, what matters is integrity. Regardless of origin, cultivation, or race, as long as you have spiritual stones, you will become the target of my harvest. Jie Jie Jie!
