Light of Cards: the Road to the Two-Dimensional King

Are cards the rules? When I traveled from the earth to another world, the cards circulating at my fingertips formed a god-killing weapon! The system's cold notification sounded in my ears: the sign-in space has been activated, and the mythical critical strike card is waiting to be received - but every time I activate the high-level card, the sharp pain of tearing my soul is warning me: if I want to sit on the arrogant magician and the cold assassin group, I must step on the corpses of the strong men in the world to climb to the top. This world will eventually be respected by my cards! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
