Background / History

Qin Feng began as a State Security officer investigating Xingye Technology, whose rapid technological advances and unusually extensive secrecy had drawn official concern. Although he acknowledged the company’s immense social contributions, he maintained that legitimate suspicions had to be investigated. During this inquiry, Xingye Technology founder Lin Xu offered him a deal: locate the missing Ayana, and Lin Xu would disclose the company’s hidden truth. 569

He became one of Lin Xu’s earliest and most consistent official partners. After Lin provided rocket-engine materials and laid out a broad list of strategic scientific needs, Qin Feng agreed to prioritize the ultra-long-range manned spacecraft project, Star Traveler One. 77

As the high-dimensional crisis expanded, Qin Feng rose from an ordinary State Security officer to a participant in the effective highest advisory body. He continued serving as Lin Xu’s intelligence officer, operational coordinator, skeptical sounding board, and protector through investigations involving the apocalypse, cross-world activity, conceptual alteration, and dimensional ascension. 482 503

Appearance

Qin Feng generally presents himself in practical, understated clothing suited to either surveillance or fieldwork. His imposing build and face can intimidate civilians, while his operational bearing remains alert even when off duty. 94 152 513

• Often wears the Jinling National Security Office’s black casual outfit while on duty. 94
• Has also been seen in a loose T-shirt and shorts during off-duty surveillance. 94
• Carries a sidearm during sensitive operations. 152
• Is a habitual smoker, though he sometimes refrains from smoking around Lin Xu. 152 178

Personality

Qin Feng is sharp, observant, and professionally skeptical. He does not accept extraordinary claims at face value, instead relying on records, surveillance, behavioral analysis, and corroborating evidence. His investigation of Qin Shizhong demonstrates this approach: he identified discrepancies between Qin Shizhong’s logic, expressions, movements, and prior “performance preparation,” concluding that the supposed cooperation was an act. 354

Despite his stern professional side, Qin Feng is notably relaxed around Lin Xu and Jiang Xingye. He frequently teases Lin Xu about his relationship with Jiang Xingye, his growing influence, and his status as “Butterfly,” but his humor is never presented as malicious. 154 169 224

He is conscious of his own limits. Qin Feng openly admits that he does not understand every scientific or economic issue involved in the Coordination Group’s work, but considers it his responsibility to understand their practical implications well enough to coordinate, investigate, and report effectively. 152 309 385

Story Role / Major Arcs

Early Cooperation with Lin Xu

Qin Feng receives Lin Xu’s rocket-engine materials and strategic requests, then agrees to prioritize Star Traveler One. This establishes him as Lin Xu’s main connection to official resources and national-security institutions. 77

Zhang Yuan and Zhou Yue Investigations

He investigates Zhang Yuan’s unexplained death, provides Zhang Yuan’s complete background profile after the resurrection, and leads the effort to trace Zhou Yue after his presumed resurrection. His funeral-home inquiry exposes forged and missing records tied to Zhou Yue’s cremation. 86 87 104

Orchid Stone 2025 and the Lanshi Project

Qin Feng interrogates Ayana, confirms her 2023 meeting with Zhou Yue on the high seas, and traces the connection to CIASAD and the CIA’s Orchid Stone 2025 project. He and Lin Xu subsequently analyze the Lanshi Project and the Western Alliance’s broader use of Zhou Yue. 153 154 178

High-Dimensional Experiencer Cases

As high-dimensional experiencers become more common, Qin Feng evaluates Yu Shiliang, investigates Qin Shizhong’s suspicious behavior, and uncovers evidence that Qin Shizhong’s apparent normality is a carefully prepared disguise. 350 354 359

Qin Shizhong and the Boundary

Qin Feng helps establish that Qin Shizhong can alter concepts through the Boundary, including erasing his own existence from others’ memories and fabricating his parents’ deaths. He investigates the timeline of the erasure, locates Zhang Ziyi, and remains wary even after Qin Shizhong agrees to cooperate. 386 388 401 415

Cross-World and High-Dimensional Strategy

Qin Feng continues supporting Lin Xu’s later plans for high-dimensional outposts, cross-world communication, dimensional navigation, and expeditions into other worlds. His practical questions and alternative proposals repeatedly help Lin Xu refine larger strategic conclusions. 372 429 483 488

Notable Quotes

“If it is suspicious, then it should be investigated.” 569

Trivia
