Han Chang

Biodata

Appearance

Han Chang is a handsome man who wears glasses. At his first meeting with Gao Yuan, he is dressed casually enough that Gao does not immediately identify him as military personnel. 34

• Wears glasses. 34
• Maintains an approachable, civilian-facing appearance despite his military role. 34

Personality

Han Chang is serious about military readiness and the welfare of frontline soldiers. After receiving strong evaluation data for Kunlun's X2 thermal fiber, he personally reports it to Ding Songlin because he wants soldiers stationed in harsh cold regions to receive the equipment before winter. 34

He is methodical and security-conscious when handling sensitive technology, taking over the delivery arrangements for X3 bulletproof-fiber samples rather than leaving them with an ordinary courier. 39 Although initially formal with Gao Yuan, he becomes warm, candid, and protective toward him as their cooperation develops into friendship. 68 205 287

Abilities & Skills

Equipment Testing and Evaluation

Han Chang supervises military evaluation of new equipment and recognizes potentially decisive technologies quickly.

• Procured X2 thermal-fiber products within his authority and sent them to key high-altitude locations for testing. 34
• Reported the resulting evaluation data directly to Ding Songlin, urging rapid frontline adoption. 34
• Organized registration, classification, and live-fire testing of Kunlun's bulletproof and cushioning fibers, even after normal working hours. 40
• Was stationed with a General Armament Department branch in the South China Sea to test deep-sea individual combat equipment. 182

Military Procurement and Security Coordination

Han Chang serves as a link between Kunlun Group and military decision-makers.

• Negotiated military cooperation with Gao Yuan for X2 thermal fiber, including a discounted military-supply arrangement. 34
• Warned Gao Yuan that advanced bulletproof materials could be restricted from civilian sale and personally assumed responsibility for securing the X3 sample shipment. 39
• Helped Gao Yuan seek Ding Songlin's intervention to recruit vulcanization specialist Li Changxing for the aviation-tire project. 59
• Brought military support to Kunlun's Kaleidoscope supercomputer project. 262

Technical Literacy

Han Chang has a science-and-engineering background from the National University of Defense Technology, supporting his work in equipment performance and military technology assessment. 274

• Understands the strategic value of aviation tires, solid-state batteries, advanced fibers, and computing infrastructure. 59 102 274
• Initially questions Gao Yuan's claim that supercomputer cabinets are part of an operating-system project, then comes to understand the project's significance. 274
• Coordinates military experts and resources for projects with defense applications. 287

Story Role / Major Arcs

• X2 thermal-fiber procurement: Han Chang receives exceptional testing feedback on Kunlun's X2 thermal fiber, reports it to Ding Songlin, and is ordered to visit Kunlun Company to pursue cooperation for frontline troops. 34
• Silver Frost testing: After Gao Yuan sends X3 samples, Han Chang ensures their secure handling and leads their immediate testing. The resulting Silver Frost fiber reaches Level 4 protection with a double-layer structure and is judged superior to Kevlar and other third-generation materials. 39 40 41
• Academic and industrial support: He relays Gao Yuan's position on Chinese-language scientific publishing to senior military figures and supports the aviation-tire project by helping secure Li Changxing's transfer from the Shuguang Institute. 47 59
• Imperial Capital liaison: Han Chang hosts Gao Yuan and Cao Feiyu in the Imperial Capital, shows them how X2 thermal fiber has improved civilian and military life in cold regions, and introduces Gao to Ding Songlin and Zhao Guanyun. 68
• Galaxy Eye and solid-state batteries: He conveys Gao Yuan's Galaxy Eye proposal to high-ranking officials and reacts enthusiastically to the military applications of the Super Solid-state Battery, particularly for drones. 95 102
• Growing military partnership: By Gao Yuan's later visit to the Imperial Capital, Han Chang explains that the military considers Kunlun an important partner rather than merely a private supplier. 205
• Computing and weapons collaboration: Han Chang brings military backing to the Kaleidoscope project, accompanies Gao Yuan to the Wuxi Supercomputing Center, and later leads military high-energy-physics experts to Sky City for the super laser weapon project. 262 274 287

Relationships

• Gao Yuan — Initially a military procurement contact for Kunlun's thermal fiber; their relationship develops into a trusted military-civilian partnership and close friendship. 34 68 205 287
• Ding Songlin — His direct superior and principal collaborator within the military hierarchy; Han Chang reports equipment evaluations to him and seeks his support for major projects. 34 59
• Li Changxing — Supports Gao Yuan's effort to recruit the vulcanization specialist for the aviation-tire research program. 59
• Liang Shaojie — Introduces Liang to Gao Yuan as the General Staff officer responsible for Kunlun Group's security. 253
• Luo Sihan — Brings Professor Luo and a military expert team to cooperate with Gao Yuan on the high-energy plasma laser project. 287

Trivia

• Han Chang jokes that Ding Songlin suffers from “firepower insufficiency phobia” because of his enthusiasm for artillery and military firepower. 34
• He states that Kunlun's rapid output has increased his department's workload from testing roughly one hundred new equipment types annually to more than three hundred. 287
