The aura of Kyushu Continent is declining, the whispers of Cthulhu are undercurrent, and when Ling Si, a loser scholar, jumps off a cliff, he is unexpectedly selected by the interstellar "Quantitative Consortium" and becomes the only interstellar courier in the world of cultivation. He is bound to the Wanjie Express Terminal and embarks on a fantasy adventure that subverts cognition.
He has no talent for cultivating immortals, but he temporarily unlocks skills with the "Mission Must Achieve" Buff, sends interstellar chocolate to heal the Iceberg Saint, delivers the gossip weekly to the Demon Lord, and helps the demon princess purchase ion hair curlers. While laughing and laughing, he met the snitch A Fei, the useless weapon refiner Tiexin, and the demon girl Taoyao, and formed the "Sisi Express" team.
However, traditional cultivation sects regard it as a heresy, and interstellar opponents maliciously sabotage it. What is even more frightening is that CCO uses express delivery projects to control the situation. The truth about the decline of spiritual energy and the awakening of the old gods gradually emerges. From dealing with the pursuit of hunters, to guarding the fragments of the old gods, to uniting with the great powers of the cultivation world and the enlightened interstellar faction to fight against the old gods of deep space, Ling Si used his wisdom and teamwork as a mortal to connect cultivation formations and interstellar technology with the express network. During the collision of the two major civilizations, he wrote a legend of counterattacking from desperate situations and protecting the two worlds, becoming the "king of express delivery" that no one dares to offend.
