Her name is 007, and she is the sharpest blade of the "Underworld" organization. She has no past, only a code name.
It wasn't until she retrieved her erased real name Yuan Yu during the mission that she discovered that she was actually the most critical "key" in the organization's conspiracy.
The leader, codenamed Jianheng, hides the cold calculation of the composite body behind his smile;
The mysterious Yuan Xi sets up a stall among the ruins, using the "eye of truth" to see through the jokes of fate;
And the monster that turned into "radium" screamed the hidden truth...
When trust becomes a luxury product and when partners are in crisis one after another,
She gripped the scythe tightly and stood side by side with the master tactician Ke Chu, the voice of healing Lian Yan, and the silent knight Qi An.
Among the ruins filled with monsters, the horrifying inside story of the "Styx Project" was revealed.
This is an escape about memory and reality.
Under the deep water, there are secrets that subvert the galaxy——
And those who hold the truth will eventually face a choice:
Become a chess piece, or overturn the entire chess game?
