Zhou Hu traveled to the different world Blue Star and became a freshman in the card-making department who just entered the university. He carries a "Book of Mountains and Seas" in his mind, which can turn its exotic beasts, gods, spiritual plants and geographical wonders into powerful cards of the mountain and sea series. When the large-scale infiltration and invasion of monsters came, he fought all the way from the campus competition to the card maker of the human alliance, and finally suppressed the monster tide with the "Mountain and Sea Card Group".
