Background / History

William was a Federal Bureau of Investigation agent assigned to investigate supernatural incidents at Lorenz Psychiatric Hospital. His investigation confirmed that Feng Buzhi's reported death was real, uncovered the hospital's connection to numerous disappearances, and led to his capture after he discovered too much. 305

He was imprisoned in an airtight “little black room” and subjected to a highest-level aptitude test. A reagent amplified every sensory input into agony; while enduring it, William unknowingly broke his bodily shackles. The hospital subsequently performed organ replacements on him without anesthesia, replacing at least his heart, marrow, and blood. 306 314

William awakened in Initial Town No. 74396 with a repaired body, abnormal learning speed, and an altered emotional state. Wallace explained the world and its race-based struggle for supremacy before Feng Buzhi appeared, identified William as potentially useful, removed his heart, and replaced it with a stronger one. Feng Buzhi kept William's original heart for himself. 314 315

Appearance

William is a blond, blue-eyed, handsome man. 493

• His body bears no visible surgical scars after arriving in the Abyss world, despite the extensive organ replacements performed at Lorenz Psychiatric Hospital. 314
• He initially appeared in a Lorenz Psychiatric Hospital patient uniform before changing into a black T-shirt and loose jeans taken from an unconscious arrival. 314

Personality

William is highly adaptable and unusually composed in the face of extreme circumstances. After waking in an unfamiliar world with altered organs and memories of torture, he quickly assessed his surroundings, concealed himself from Wallace, and investigated his own condition. 314

His experiences at Lorenz Psychiatric Hospital and under Cult Leader Feng have changed him. During the reincarnation ritual, William realizes that his desire to escape Feng has gradually become attachment and reverence, a transformation he finds disturbing but cannot easily reject. 341

He is patient when explaining the current world to Francis, pragmatic about cultivation, and cautious about accepting major opportunities such as a contract with Zdenek before consulting Feng Buzhi. 370

Abilities & Skills

Enhanced Learning and Physical Adaptation

William's modified body and broken shackles grant him exceptional adaptability.

• Learned to ride a skateboard in seconds after initially failing to balance on it. 314
• Can correct his body unnaturally in midair and land safely. 314
• Possesses a mental “switch” that sharply improves the fluency of his thoughts, though maintaining it puts severe strain on his body. 315
• His arrival in the Abyss world repaired old injuries and allowed his replaced organs to fuse without visible scars. 314

Bizarre-Organ Control

William contains multiple bizarre entities and implanted powers, yet keeps them under unusually complete control.

• The reincarnation ritual substantially improved his control over the bizarre elements within his organs. 341
• Francis finds several bizarre entities in William's body, but notes that they behave “like obedient children” and can be perfectly controlled by William. 370

Riggs-Family Eyes

Francis grants William special eyes connected to the Riggs bloodline.

• Resist bizarre corruption. 367
• Accelerate spiritual-realm cultivation. 367
• Function as an additional bizarre organ. 367
• Serve as the key to Francis's hidden treasure. 367 368

Multi-Body Control

William can operate bodies across worlds with notable efficiency.

• Simultaneously controls bodies in both worlds more smoothly than ordinary researchers because he is a genuine cultivator. 576
• Correctly identifies the limitation in Zhao Liang's repeated body-creation and fusion process. 576

Relationships

• Feng Buzhi / Cult Leader Feng — Initially William's captor and the source of his forced organ modifications; later his registered master within the Human Sect. William's attachment to Feng grows despite his earlier wish to escape. 315 341 369
• Francis Flavio Riggs — William's grandfather, whose weakened spirit enters William's mind, grants him inherited eyes, and guides his cultivation. 367 369
• Wallace — Feng Buzhi's former attending physician and the manager of Initial Town No. 74396; he explains the Abyss world to William after their reunion. 314 315
• Ku Le — Frog-Man follower who becomes attached to William because remnants of Feng Buzhi's former organs remain within William. 365
• Ouyang Ming — Human Race prophet whom William accompanies and protects from the worsening consequences of repeatedly peering into fate. 493 494
• Broken Fang — Azure Dragon and fellow Human Sect cultivator; William advises him during his attempted transformation into human form. 370
• Zdenek — Shadow Blood Dragon who offers assistance; William postpones forming a contract with him and obtaining the False Dragon bloodline. 369 370

Story Role / Major Arcs

Arrival and Completion

William's emergence is accelerated by Feng Buzhi, who seeks to exploit the prophecy of a Trialist named William leading humanity toward a bright future. Feng captures him, subjects him to testing and organ replacement, and brings him to Initial Town No. 74396. 304 305 315

Reincarnation Ritual

William earns a first-tier evaluation in the Human Race reincarnation ritual, surpassing the other trial-takers. The experience strengthens his control of his bizarre organs and makes him recognize his growing psychological attachment to Cult Leader Feng. 340 341

Human Sect Cultivation

Following the ritual, William acts independently to strengthen the Human Orthodoxy and pursue true immortality. He is recognized as a first-rank cultivator and considers—but postpones—forming a contract with Zdenek. 365 370

Francis's Inheritance

William follows a guiding sensation into the sea, where Francis's spirit enters his body. Francis grants him the Riggs-family eyes, reveals the existence of a hidden treasure, and recounts the Human Race's earlier decline after his betrayal. 367 369

Twilight Crown and Future Prophecy

At the Ancestor Banyan Tree, Ouyang Ming recalls a future in which William leads humanity to glory, forms the Twilight Guard, and allies with the elves. William learns that the ninth-rank secret treasure, the Twilight Crown, may offer a route to second-rank advancement. 493
