An out-of-control space-time experiment plunged Lin Yan's consciousness into endless wandering. From the Shanghai Concession under artillery fire in the Republic of China, to the apocalyptic ruins ravaged by acid rain three hundred years later; from the palace shadows surrounded by red walls, to the sword shadows crisscrossed by swordsmen, she wandered repeatedly in the broken time and space, with the only anchor point being the man who transcended identity and memory.
He is the warlord Marshal Gu Yanchen, the apocalyptic scientist Shen Zhiyu, the cold-faced dead warrior Ji, and the knight-errant Qingxuan... In every life, he has faced a completely unfamiliar identity with a blank memory, but he can always arrive as scheduled when her life hangs by a thread, and uses his instinctive protection to carve a bond that spans time and space.
The cinnabar mole is his unchanging mark, and sacrificing one's life to protect each other is his unresolved obsession. When the memory fragments were put together layer by layer, Lin Yan was shocked to realize that this repeated reunion and separation was a seal set by his soul - in order to retain her consciousness, he was willing to exhaust himself in the long river of time, letting love become an endless wait.
Above the ashes, love lives on. They traveled through thousands of years, fighting against the backlash of time and space and the attrition of souls, just to hold the glimmer of light belonging to each other at the end of chaos and break the fateful closed loop of "reunion and separation".
