Luo Ning, a junior student, unexpectedly obtained the [Portable Card Drawing System]. He can draw a "life card" every day. From "Memory Bread" to "Time Pause" to "Emotional Perception", the card effects are all kinds of strange. It was supposed to be a daily routine of easy healing, but due to an accidental card draw, Luo Ning discovered that his roommate was actually an alien detective lurking on the earth!
In order to hide their identity, the aliens began to "investigate" Luo Ning frantically, trying to find out the truth about the secrets he knew. Luo Ning, on the other hand, used the card drawing system to stage "hide and seek" counterattacks one after another in seemingly daily campus life. Is the dormitory aunt an alien intelligence agent? Is the librarian an interstellar agent? This "detective game" is about the survival of the earth. Under the surface of comedy and healing, there are undercurrents.
Luo Ning discovered that there was more than one "detective" sent by aliens, and his card drawing system seemed to be inextricably linked to an alien civilization. When "daily" and "invasion" overlap, a "healing" interstellar war quietly begins.
