The Green Demon

As sword masters and cultivators of spiritual energy, Green Hazes have been the ghost specialists ever since ancient times. Yet, Lin Luson, current Green Haze of the country, has lost his energy completely and fallen ill after his master's death. The country is falling into chaos as ghosts and monsters get free reign.
Then a young man, Fengmian Fang, appears on his doorstep, determined to learn his ways and help him heal. But what Fang doesn't tell him is that he is a demon, sent by his contractor to kill him once all of Luson's knowledge has been shared.
To make things worse, feelings tend to have their own plans, tying the men closer to each other than any of them ever expected.

An English fantasy story inspired by Chinese wuxia/xianxia/cultivation setting.
