Faceless is already the master of the Blood-clothed Building and the Shadow Pavilion. He controls two opposing forces at the same time, but no one knows the secret of his identity. Suspicions arose within the Shadow Pavilion due to repeated failed assassinations of the Blood Clothes Building. The third elder launched an internal investigation. At the same time, an anonymous letter "Do you still remember your face?" Appeared, and an old friend claimed his life. Technique: The protagonist constantly changes his face, lurks among the major forces, and uses information gaps to manipulate intelligence and assassinations to delay the truth from being revealed. Obstacles: Shadow Pavilion's suspicion deepens. The identities played by the protagonist have rebelled or died one after another. His lifespan has been greatly consumed, and his self-awareness has begun to blur. Price: The protagonist is eventually trapped in a strange body, the truth is exposed, and everyone is betrayed. He designed the Bloody Clothes Tower and the Shadow Pavilion to perish together, bringing all the secrets into the Bronze Mirror. He lost all his identity and was alone in front of the mirror, unable to remember his original face, realizing the ending of "all living beings are me, but I am no longer anyone".
