Jinggang City is a steel jungle divided by plutocrats and neon lights. The only official agency that can fight against the alienated monster "Erosion", the "Special Investigation Bureau", is actually secretly controlled by a mysterious organization called "Ouroboros".
Lin Wan, a newly hired archivist, joins the Special Investigation Bureau in order to find her missing sister. An accidental supernatural power trigger allowed her to see the truth of the "Red Zone Riot" three years ago on the murder weapon - the figure who cold-bloodedly brandished a knife in the sea of corpses and blood was exactly the same as her immediate boss, ace executive Shen Qingqiu.
As the investigation deepened, Lin Wan discovered that Shen Qingqiu had not only lost key memories, but also lurked in his body the same power as the monster. When the sleeping "first generation" wakes up in the rainy night, and when the Special Bureau's conspiracy is revealed, the two women who were originally on opposite sides are forced to stand back to back in the center of the storm.
From the betrayal and pursuit of the Special Bureau, to the crazy plan to destroy the "embryo of God", to the face-to-face confrontation with the false god who attempts to create a "perfect new god". On the edge of sanity and madness, Lin Wan must use her soul to feel Shen Qingqiu's pain and awaken her sleeping memories; and Shen Qingqiu must also face the sins she has personally created and completely control her own power.
The night is long and the embers will be extinguished. Amid the malice of the entire world, they want to use their mortal bodies to cut down the false gods who are above them, and fight their way to the dawn. On top of the ruins, their scars finally faded away, and in the ordinary smoke and smoke, they ushered in a new life that truly belonged to "human beings".
Purpose: Redeeming each other in the abyss: The story profoundly explores the proposition of "trauma and healing". Neither Shen Qingqiu nor Lin Wan are perfect heroes in the traditional sense. They each have their own imperfections and pain. True redemption is not unilateral salvation, but two broken souls accepting each other and serving as anchors in desperate situations. Lin Wan accepted Shen Qingqiu's tyranny with empathy, and Shen Qingqiu used strength to protect Lin Wan's softness. They completed self-reconciliation with each other.
The imperfection of human nature and the illusion of divinity: "Ouroboros" attempts to create a "god" that is painless and absolutely rational, but the experiences of the protagonists prove that it is the pain, struggle, fear and love that constitute true humanity. The real salvation is not to become a lofty god, but to support each other in suffering as human beings and bravely embrace the imperfect reality.
The long night will ember, but the glimmer of light will never go out: "Long night" represents the years of suffering, forgetfulness and despair, while "ember" represents the remaining warmth and hope after burning. Even if the world has collapsed, even if the memory has been erased, as long as there are still people willing to remember, empathize, and resist, that weak spark will never be completely extinguished. The ending of the story, in which they rebuild their ordinary lives on top of the ashes, is the warmest interpretation of this idea.
