As scarlet slime dripped down the temple, fractal tentacles began to grow from the roars of the zombies. The time traveler "Ling Xuan" is not a warrior, but in the strange RNA pattern of the virus, he sees the shadow of the chaotic mathematics notes left by his grandmother. Joining hands with the marginalized genius virologist "Pei Yuanzhou", they discover that the essence of this doomsday plague is actually the evolution of the "chaos topology" from the abyss in the real dimension. In the abandoned CDC laboratory, use your grandmother's formula to fight against indescribable distortion; in the churning crater of Yellowstone, face the source of entropy increase. This is not a conquest of power, but a glazed net woven with topology, virology and the memory of the dead to bind the torrent of chaos called "Cthulhu". Can the world regain a trace of linear order amid the non-Euclidean horror?
