When a pretty immortal teenager runs into a sickly schemer, their fates become entwined… "Did he get close just so he could eat him?!" An immortal seeking to end his life, a mortal seeking to prolong his life. When the two with the opposite fates meet, what awaits them? Will they be each other's remedy or poison?

For the crime of stealing the Fair Wind Scroll, He Xianzi was expelled from the celestial realm, his soul destroyed. But just before his execution, he made his disciple, San Tu, promise him one thing: grow up well. Now, thousands of years have passed. San Tu has made great progress in the world of cultivation. Now, he's ready to descend into the mortal realm in search of his long-lost master. It's there that he meets a man who looks exactly like He Xianzi—as if he is his very reincarnation—though he claims to know nothing of the master. Thus begins the story of two fated souls locked in an epic battle of good versus evil.
