Lin Xia, the successor of the Sanxingdui Symbiosis Seal, holds a bronze fragment with a faint light flowing through the lines and hiding an unknown consciousness. Following the contradictory clues left behind by his father's "fake death", he traces the secret of symbiosis between the Yinghuo clan and the Chinese ancestors for thousands of years. The mysterious keeper Aji, whose origins are mysterious, the cryptic keeper Professor Chen, and the strange beasts from "The Classic of Mountains and Seas" who frequently appear, together form a web of mist that spans time and space. Lin Xia traveled through the five prehistoric secret realms to collect the Five Elements Mysterious Keys, only to find that everyone around him had a hidden past, and in his own blood, secrets that could subvert the order of the universe were actually sleeping. When the "Symbiosis Soul" cuts through space, it is not only the ultimate truth revealed.
