The old days have fallen, and spiritual fragments have polluted the world. Human beings rely on contracts with monsters to advance through the ranks, becoming stronger and more insane.
Shen Lian was betrayed by the organization and awakened his silent brain, which can control the rules of all things.
There is no heroine, but he kills decisively, abandoning his son from the Gray Realm, and fights his way to the top of the Abyss Sequence!
Intention: Real strength is not to succumb to madness, but to stay awake in the abyss and control power with reason.
