Over time, the city gained its own spirit and became home to the Su Zhao Clan. Generations later, Princess Luo Wei and her foster brother Fu Chenzhi are torn apart by betrayal and fate. When Luo Wei joins an immortal sect, she reunites with Fu Chenzhi and meets their master—the revered God Yin Ze. As admiration turns to forbidden love, the destinies of gods and mortals become deeply entwined.
