Shui Yue Dong Tian.

Taking place in about 294 A.D., during the Western Jin era, it is the story of three young men, the Tong brothers, who live with their clan and family in a secluded valley protected from the outside world. No one in the valley has left it for five hundred years, ever since the mighty general Long Teng brought them there for protection. Since the dawn of time, members of the clan had used their gifts of divination, spiritual intuition and magic to serve the Emperors, but were betrayed by an ambitious, half-mad relative. Now, the boys venture to the forbidden outside world in search of healing magic for their dying father, discovering mortal danger, friendship, and passionate love. A branch of their own family remains powerful in the martial arts world, and an ancient enemy still lives.
