800 years ago, Xie Lian was a pure-blooded and noble Crown Prince, a well-regarded child of Heaven with unlimited potential. But who knew that, after he ascended and became a god with tens of thousands of worshippers, his fate would take such a sharp downhill turn? He was demoted again and again, and fell to rock bottom. 800 years later, Xie Lian ascended again, but this time, without worshippers or and without incense. One day, after returning from collecting scraps, he took a mysterious young man home. And this young man was the Ghost King that made others pale in fear whenever discussed—Hua Cheng.
