Empty Card: Era of Two Realms

(It's not a fast-food novel, it doesn't have a golden finger, it's an all-staff system, and the protagonist can't save the world by himself) On a rainy night, a death call broke the peaceful life of Xia Ci and his sister. Ten years ago, his father Xia Cheng disappeared from the world, leaving only an empty grave. Ten years later, his adoptive father Xu Xiang died mysteriously and tragically, and the cause of his death was confusing. Looking for the truth, the mysterious disappearance or death of more than a million people around the world every year actually points to the same terrifying answer - the infinite world has quietly arrived, and mankind has officially entered the dual world era. His father's message, his adoptive father's death words, his sister's murmur, and the unknown mystery... All of this pushed Xia Ci into an invisible web. Xia Ci knew: If you want to break this game, you must enter the game first! And when he stepped into this unknown world with four dark gold dice in his hand, he found that in a world where card abilities were valued, what he got were empty cards with no effect...
