The same old story of an immortal and a mortal. Fang Pingxu, a prince with a limp whom the common folk call the God of War. Mang Chun, a little deity who acts like a rascal but saved the God of War. As a carefree immortal, Mang Chun is always dropping by the mansion of Fang Pingxu, the carefree prince, to freeload meals and drinks, staying an extra day whenever he can... But then a murder case shatters it all. The mountain rain brings death, strange cases throw the world into chaos, the immortal path is elusive, demons descend, and one gives their life for the Dao... At the time, it all seemed ordinary; by the time they retraced their steps, it was too late. Switch couple, no set top or bottom. P.S. The historical setting is fictional, and the titles for the immortals are original. For example, the Spring God isn't the bird-bodied, human-faced figure from ancient mythology; that's an original setting. Just read for fun. A simple story.
