[A high-quality, million-word completed fanfiction is already available; you can read it with confidence.] The transmigrator Fen Yu's cheat ability, [Entangled Fate], remained dormant for sixteen years, preventing him from receiving blessings, until the arrival of Fukaros, the goddess of water and justice who had unexpectedly lingered in the celestial realm.

However, his passive skill, [The Abyss of the Gaze], also went berserk. The dungeon began to breed monsters that should not exist. Abyss mages chanted incantations, frost-covered flowers quietly bloomed, and blasting trees grew deep within… until the phantom of the Judgment-class Honkai Beast Benares roared. Orario's common sense was crumbling, guilds descended into chaos, and the gods trembled in a mixture of revelry and fear. "Look, Fen Yu, this is the 'possibility' you brought." Furina looked at the boy beside her, her eyes gleaming with anticipation. "So, should we let the abyss devour the world, or..." Fen Yu clenched his fist. On the system interface, a new [Entangled Bond] was slowly forming. "...Or should we use our 'justice' to bring a grand 'judgment' to this labyrinth of despair?"
