Lu Pingfan, a courier who retired due to injury, was drawn into the infinite flow world called "Demon Path" to save a white cat. His mission is not to survive or kill, but to complete "designated deliveries" for various bizarre copies - delivering serum to the apocalyptic base, delivering a love letter to the ancient flower demon, and delivering a truce to the warring demon gods. The arrogant master bound to him was actually the useless white cat he rescued. When Lu Pingfan relied on time management and route planning to the limit of mortals to deliver goods on time in life and death missions, the entire demon world on the verge of collapse discovered that this "waste" with no spiritual roots and his cat delivered not only packages, but also "hope" to reshape the rules of the world. This is a story about punctuality, trustworthiness and protection. In the most disorderly and desperate situation, using the simplest professional creed to find a way out.
