Darkness falls, the sky is covered by invisible forces, and the world falls into apocalyptic chaos. Su Wan, an ordinary college student, accidentally awakens to the card system. She can obtain cards by killing monsters. Among them, the rarest legendary "Sky Covering Card" can temporarily obscure the secrets of the sky and suppress all dark creatures. She used her card abilities to survive in the ruins, and gradually discovered that behind the darkness was the invasion of the alien civilization "Zhatian Clan". They blocked the earth with their giant hands that covered the sky, trying to trap humans as a source of energy for cards. Su Wan grew up step by step from a weak card collector to form a survivor alliance to fight against the Zhetian clan. In the end, she gathered seven sky-shielding cards, activated the ultimate sky-shielding formation, tore apart the curtain of darkness, let the sun shine on the earth again, and saved human civilization.
