As the 7th duke, Yin Chen has the ability to wield the power of the wind, fire, water and earth. As he tries to protect his disciple Qi Ling, he uncovers an earth-shattering secret.
During the 15th century B.C., the descendants of previous emperors were caught in an endless battle for the rule over Shang. Although Yang Jia succeeds in assuming the throne, the nation has become rife with internal and external turmoil. According to legends, the one who obtains the help of Chi You's descendant can rule the world. Yin Chen leads the search in hopes of ending the conflict. Qi Ling is a young man from a small village who becomes Yin Chen's disciple by chance, thus beginning his extraordinary journey.
After a long slumber, Wu Xin wakes up during China's new Republic era. He is a wandering immortal who lives a hungry and penniless life. He has no recollection of how long he has lived or how he came to be, but he has powers where he can sense the presence and communicate with spirits good and evil that still roam the living world. He pretends to be a monk to make a living.
During his latest slumber, he wakes up next to Li Yue Ya. She has just run away from home to escape a forced marriage to an elderly man. Seeing how hungry Wu Xin looks she offers him her last bit of food. The two head to Wen County. To repay her act of kindness he follows her and promises that tonight the two will feast and have a place to stay. He uses his powers to search for evil spirits that intend to do harm to the living and rid them from the living world. Together the two set off pretending to be siblings to find whoever is in need of his services. At first, Yue Ya does not believe Wu Xin and thinks he is a con artist until she assists him in his first job to rid an angry evil spirit residing at the local warlord's home. As the two progress on their journey, friendship and then romance form between the two.
