The top forces in the nine regions: the "Taichu Immortal Sect" in the Canglan Region, the "Extreme Cold Palace" in the Xuanbing Region, and the "Great Xia Dynasty" in the Central China each control part of the "Chaos Fragments" (the key to the Chaos Origin Sea), and the "Qingji Town" where the protagonist is located unexpectedly appears. The discovery of a "Sky-Swallowing Demon Coffin" (which contains a map of the Origin Sea of Chaos) triggered a struggle among the nine realms, and at the same time revealed the mystery of the protagonist's life experience - his mother was actually a powerful "Swallowing Sky Realm" thousands of years ago, and her memory was sealed and banished to the mortal world because of her resistance to the "Tiandao Alliance".
