The second lady of the Gong family, one of the three major families in Gaoyang City, the eighteen-year-old eight-star spirit master, and the owner of many titles such as the future leader of Gaoyang City, Gong Yingxue, looked at Lu An, waved the deed of sale in her hand, and said as if stating the facts. ………… It's a world shrouded in mist, with powerful beasts, countless treasures, relics left over from pre-epoch eras, and even weird fog demons and other races. The strongest of the human race, also known as the Psychics, struggled to explore the world in the mist, while also building city-states on which humanity depended. Lu An traveled to this world and found that his predecessor had run away owing a huge amount of money, and his predecessor committed suicide in despair, leaving behind a mess.

Fortunately, an unnamed book appeared in his mind, and he could perceive and deduce all kinds of knowledge. Extrapolate and evolve, beyond the limit. Lu An felt as if he was about to take off.
