Impostors?!

Doppelgangers + No System + No Cultivation + No Transmigration In a modern society where technology intertwines with fantasy, doppelgangers, a species long thought to exist only in people's imaginations and science fiction, suddenly become a threat to the real world. They are remarkably lifelike, almost indistinguishable from humans in their appearance, behavior, and even thought, making it difficult to tell the real from the fake. For ages, doppelgangers were dismissed as imaginary creatures. Now, they have truly arrived. X University is unfortunately the first target of the doppelganger invasion. The peaceful campus is thrown into chaos in an instant, and terrified, uneasy students search for a way to survive. In this sudden disaster, Wang Zimo, an ordinary college student, and his roommates are forced to face challenges unlike anything they've ever known.
