After Practicing for Hundreds of Generations, Immortal Master Also Wants to Play the Cultivation System

A high school student accidentally traveled to a world where cards are respected. People here can use the power of cards to strengthen themselves. It is different from a card competitive game, but absorbs the power of cards to fight. Fly into the sky, enter the sea, escape from the earth, move mountains and reclaim seas, and even live forever! All this is attracting this middle-aged boy with a bit of talent. What? Do you want to be a card holder? Do you have any talent? Do you have any background? You have nothing and still want to be a card holder? Anyone who comes here is demoted to a handyman. Things that are an eyesore are disgusting]
