After Jiang Ran, an ordinary delivery boy, suffered a car accident, he was accidentally bound to the Esophageal Book system, traveled to the world of cultivation, and became a unique Tiandao delivery boy. His delivery items are not ordinary meals, but spiritual delicacies, elixirs, and even heavenly catastrophes. Once he receives a bad review or the delivery times out, it will trigger a heavenly catastrophe or even a crisis of annihilation. At the beginning, Jiang was looked down upon by the monks because he had no spiritual roots, but he relied on special delivery rules to save himself from danger many times. While taking orders to accumulate credit points and improve spiritual roots, he also dealt with opponents from all walks of life who maliciously wrote bad reviews and cut off orders. He successively faced off against forces such as the Spirit Sword Sect and the Blood Demon Sect. On the way, he met Jianzun Zhongxiao, and the two traveled together. Jiang Ran successively defeated the behind-the-scenes villains such as Wan Xiangzhenren and Murong Qingluan, cracked the black market bad review industry chain and the ancient sky-breaking formation, and along the way unlocked the abilities of time and space distribution, heavenly judgment and other abilities. In the end, he counterattacked and became the master of heaven, opening up the delivery channel between the cultivation world and the fairy world. From then on, he traveled back and forth between the two worlds to take orders, making delivering heavenly tribulations and overcoming thunder tribulations a daily routine. As a special deliveryman, he took charge of the order of heaven and earth.
