As the world's operating cycle enters a new turbulent node, the seal of the "mountain and sea realm" that has been dormant for thousands of years begins to loosen, and ancient beasts quietly return to the world. An ordinary migrant worker named Mu Lin was in a trance because he had been entangled in strange dreams for many years, but unexpectedly discovered that he had memories and perceptions that were different from ordinary people.
At the foot of Mount Lushan, during an ordinary National Day mountaineering trip, he encountered a mysterious "grandfather and grandson group" and witnessed an extraordinary battle where reality and dreams intertwined. At the same time, Tao and Zhai, who have lived in seclusion in Lushan for generations and guarded the ancient seal, also noticed something strange. When the masters of the association, the hidden family and the escaped beasts met on a narrow road at Wulao Peak, a conflict concerning the fate of the two worlds quietly broke out. Mu Lin, who knew nothing about it, was gradually drawn into this whirlpool that exceeded his understanding. His dreams, his memories, and the mysterious fragments of information he accidentally obtained all seem to be closely related to this great change in the millennium reincarnation.
Humans and alien beasts, seals and returns, loyalty and betrayal... In the prelude to the reality of myths, ordinary workers, hidden guardians and ancient inheritors stand together at the fork in the road where the wheel of history restarts.
