The Hidden Expert with Cheats in the City

Fang Xiuzheng has cultivated at the Kunlun Sect since childhood and has never set foot in the mortal world. Following his master's orders, he descends the mountain to gain experience, lives incognito in the city, settles his mortal ties, and saves the continent from danger. He uses the Book of Changes to understand the world, medicine to save lives, and martial arts to strengthen his resolve.
