Courier Chen Mo, 24, works hard to save his sick sister. During a thunderstorm, he was accidentally bound to the inter-dimensional express delivery system and was forcibly transported to the zombie wasteland, where he began a life-and-death trial.
The surface of the earth is peaceful, but secretly cracks in other worlds appear frequently. He can package the trophies from other worlds and send them back to the country's designated receiving station in exchange for points and permissions.
In the first mission, he narrowly escaped death. His teammates betrayed him and he took the core alone. When the return journey began, the military was shocked and established the Alien Resource Management Bureau, officially appointing him as mankind's first interdimensional messenger.
Every piece of loot is related to the survival of civilization, and every transmission is a gamble on life. He is a courier and the only hope to protect the future of mankind.
