There is a battered temple called Xuan Yuan Guan that sits in the mountains. For as long as Yi can remember, he has been living here with his master. The master tells him that Xuan Yuan Guan was founded by an immortal. The immortal had thousands of apprentices back then. This story has slowly become a legend. But is any of it true? After the death of his master, Yi now wonders if it is possible to cultivate himself and become an immortal as well.
