Deep in the mist of Shiwanda Mountain, Yinchen is the last gravekeeper of Longshou Valley. When Yue Qingyang, a descendant of the old enemy Yue family, broke into the forbidden area with his mother's relics, a truth that had been covered up for a hundred years was forced to be revealed - what they were guarding was not an ancient tomb, but an ancient observatory connected to the spiritual veins of the world.
The three broken rings reunited and activated the "Spirit Vein Locking Array" buried deep in the earth. This giant bronze city is both a cage and a cradle, imprisoning unknown beings that can reshape the world. As various forces compete for the ring, Yin Chen and Yue Qingyang discover that their bloodline is not only a key, but also the final firewall of the entire system.
From the Thousand Coffins to the Bronze City, from the Arctic ice fields to the deep sea ruins, the two must choose between trust and betrayal. When the "Guardian Agreement" is activated and the fate of individuals is bound to the survival of the planet, they choose to become a bridge between human civilization and ancient heritage - even at the cost of merging with bronze and watching the next forty-nine years of reincarnation.
This is a story about betrayal and loyalty, sacrifice and hope. When the star map lights up again and the deep space signal is sent out, the two chosen souls will make the final decision at the top of the world: Should they seal the secret forever, or bravely embrace the rite of passage of mankind in the universe?
