[No System + No Cultivation + Everyday Life + Comedy + Battles + Ensemble Cast] In 2190, on Blue Star, the United States secretly conducted human experiments. But bacteria mutated inside the test subjects, turning them into flesh-eating ghosts. Humanity had no way to kill the ghosts, allowing their ranks to grow ever stronger, and the United States became a stronghold for them. Some ghosts even awakened powerful supernatural abilities and came to be known as Ghost Kings. After humanity united in the struggle, a small number of people awakened as Ghost Mound swordsmen, and a bloody battle between humans and ghosts began on Blue Star.
