Contract Ghost Card: I'm a Healer, Yet I Become a Natural Disaster

In a world of cards, everyone can awaken their own destined card on the day they come of age, giving them the chance to become a Card Mage and defend against invading monsters. The 52 cards, including spades, hearts, clubs, and diamonds, represent countless different superpowers. Qin Tian transmigrated here and awakened the Two of Diamonds as his destined card. Among the four suits, the Two could be the lowest card, or the highest. Although Qin Tian was born with a full reserve of magic power, he was a healer, mocked as a "useless healing card." Little did anyone know that he had also awakened a unique hidden card: the Joker. His right hand commands life, his left hand holds death! With life and death coexisting, Qin Tian gained the astonishing power to summon the undead. As long as his summons survived, Qin Tian would never die, roaming between life and death. "Whatever doesn't kill me will only make me stronger!" "I am the god who protects the world, and the demon king who destroys the abyss!" Years later, when the Abyssal Demon Lord descended upon Blue Star, he saw Qin Tian seated high upon a throne of bones, looking down on all living beings. "Endless skeleton warriors!" "An army of billions of mage spirits!" "Countless undead bone demons!" "Can you withstand them?"
