This is another world known as the Starcard Continent, where card masters reign supreme. At sixteen, everyone can awaken a card space, then draw, train, and build decks for duels and battles. From street matches to wars between nations and clashes with magical beasts, everything revolves around cards.
Cards in this world can only be created from local magical beasts, martial artists, and mages. Their abilities are limited, and their potential is extremely low. No one knows that beyond this continent lies the endless expanse of the Myriad Worlds: worlds of martial arts, immortality, fantasy, science fiction, primordial myth, and more. The mighty from countless worlds can be projected into the Starcard Continent by special means, becoming its most powerful cards.
The protagonist, Lin Chen, transmigrates from Blue Star and is reborn in the body of a good-for-nothing boy in this world. After awakening the Myriad Worlds Card System, he gains the ability to connect to the Myriad Worlds and draw their powerful figures as his exclusive cards. These cards possess complete abilities and unique skills far surpassing those of local cards, and can even trigger bond bonuses with cards from the same world. Rising from a good-for-nothing to the top, he eventually uncovers the truth of the world and leads the mighty of the Myriad Worlds against the apocalyptic demons from beyond.
