Inheriting his grandfather's shabby antique shop, Shen Mo just wants to eat and die. Who would have thought that a strange black jade cicada would lead to a life-threatening pursuit and the "protection" of a mysterious master! It is called the "Xuanshu Secret Key" and involves a lost ancient legend and a terrorist organization called the "Ming Yao Society". Forced to embark on a journey westward to explore the "ancient ruins", he is surrounded by loyal and courageous friends, and a silent strongman who is difficult to distinguish between friend and foe. Behind the mystery left by grandpa, is it a shocking treasure or a taboo that can subvert the world?
