Programmer Qi Yue discovered a mysterious portal in his rented apartment and accidentally transmigrated to an apocalyptic world, where he witnessed zombies overrunning everything and humanity on the verge of extinction.
Qi Yue rescued scientist Lin Xiu from a zombie attack and learned that this world was a parallel Blue Star, where a zombie virus had erupted three months earlier.
Qi Yue faced the moral dilemma of whether to report the portal connecting the two worlds to the authorities. He worried he would be treated as a madman or lose his freedom, but realized this might be the key to saving both worlds.
Qi Yue ultimately decided to contact the national security department and meet Director Zhao of the Special Affairs Office, using an advanced chip he had brought back from the apocalyptic world to prove his discovery.
The state quickly formed a special task force for the Dual-World Portal Project. Qi Yue was appointed technical advisor and began working with the military and scientists to explore the apocalyptic world.
Qi Yue led a special forces team through the portal to the apocalyptic world on a mission to rescue scientists and collect technical data, where they were attacked by a horde of zombies.
During the retreat, Qi Yue volunteered to stay behind and cover his teammates, displaying courage in the face of death. His teammates eventually rescued him.
