Background / History

Family and Awakening

Li Xin comes from a family of accomplished adults: his grandparents teach at a university, his parents are successful businesspeople, and his uncle, Song Linwei, is a researcher. His own grades are poor. After reviewing his background, Sheng An suspects that pressure from such outstanding relatives has contributed to his rebellion 22.

Before awakening, Li Xin already believed meteorites would bring an apocalypse and tried to stop attending school. His father forced him back. Gaining powers strengthened his conviction that he should abandon school and become a world-saving superhero 21 24.

Song Linwei posted details of Li Xin’s abilities online to verify the apocalypse and assess the government’s attitude toward ability users. He hoped to negotiate protection and benefits for his nephew, but Sheng An identified the family’s intentions and rejected that approach 19 24.

Arrest and Recruitment

Eighteen days before the apocalypse, Li Xin appeared before his family in a golden metal form, declared himself Iron Man, and jumped from their seventeenth-floor apartment to begin “saving the world.” He used the building’s metal security bars to descend and landed directly in front of Sheng An 21 22.

Li Xin refused her arrest warrant and climbed another building while ordinary bullets bounced off his body. Sheng An brought him down with an aqua regia bullet, then secured his surrender with the special police. His father subsequently beat him with a broom for causing the public disturbance 22 23.

At camp, a specially modified interrogation room immobilized his metal form against its walls and ceiling. After six hours suspended overhead, Li Xin apologized and agreed to testing. Sheng An showed him how to release his feet first, then caught him when exhaustion made him stumble during the descent 25 26.

His cooperation did not last: he deliberately destroyed laboratory instruments worth ninety-seven million and nearly injured a researcher. Rather than make his family pay, he accepted three months of state service in exchange for clearing the debt. Sheng An reinforced the contract with terms attacking his heroic self-image if he broke his promise 27 28.

Life in Group B

Li Xin expected important superhero duties but was assigned intensive classes instead. His family received camp jobs, with his grandparents and uncle joining his teaching team and his parents monitoring his progress 28 29.

He initially admired Jiang Yu as a seemingly ideal novel protagonist: a reborn woman with a farming space. Their first meeting became an argument after they collided in a corridor, but discovering that both were exhausted by compulsory study quickly turned them into companions in misery 30 31.

Despite resenting Sheng An’s discipline, Li Xin supported Group B during its confrontation with Qiu Yu’s team. He wanted to fight Group A and worried openly about its larger roster of powerful ability users 34 35.

He later accompanied the operation against Long Tianyu and his companions as an observer. The operation exposed him to another formidable ability and prompted him to think more seriously about how his own metal form could counter an opponent 46 47 49.

Appearance

Li Xin is a fairly good-looking, youthful boy, slightly taller than Sheng An, with an openly defiant expression 22 23.

• Hair: Slightly overgrown, partly covering his eyebrows and eyes 23.
• Human clothing at arrest: Teddy bear pajamas beneath his metal covering 23.
• Metal form: Glittering gold, with a helmet, face-covering mask, and mechanical-looking limbs that make him appear larger 21 22.
• During intensive study: Dark circles, a dazed expression, and visibly exhausted movements 30 31.

Personality

Li Xin interprets his powers through superhero stories, imagining himself as the protagonist destined to save humanity. He enjoys dramatic entrances, boasts about invulnerability, and initially assumes the government should treat him as an exceptional figure. Learning that other ability users and reborn people already exist deeply wounds his pride 21 22 24 25.

He is impulsive, argumentative, and impatient with schoolwork and testing. His recklessness includes stealing a child’s Ultraman figurine because the child “didn’t believe in the light” and destroying expensive research equipment when frustrated 24 27.

His heroic pride is also an effective means of controlling him: being branded a coward, promise-breaker, or enemy of Iron Man troubles him more than an ordinary threat. Beneath his defiance, he cares about his family and refuses to let his parents bear the cost of his destruction 27 28.

Li Xin can recognize loyalty and competence even while resisting authority. He briefly finds Sheng An dependable after she catches him, presents a united front against Group A, and begins acknowledging the practical value of his studies 26 34 49.

Abilities & Skills

Metal Control and Bodily Transformation

Li Xin can manipulate surrounding metal and transform his own body’s elemental composition into metal. Researchers consider his control extraordinary for someone newly awakened 26 29.

• Uses metal security bars to descend and climb buildings 22.
• Forms mechanical arms, metal hammers, a helmet, and a mask 21 25 26.
• Transforms individual body parts independently, including his forehead, hands, feet, and upper body 23 25 26.
• Can use existing metal directly or form armor from nearby metal 29.
• His early transformed body consists mainly of copper and gold, with a small amount of iron; his limited knowledge restricts which elements he can produce 23 29.

Durability and Vulnerabilities

His metal form withstands ordinary gunfire and survives the fall after Sheng An shoots him while he is climbing the building 22 23.

• Chemical vulnerability: Sheng An’s aqua regia ammunition eats through his metal arm and causes severe pain 23.
• Damage control: He deactivates his transformation and breaks away the affected mechanical section, leaving his human hand intact 23.
• Containment: The modified interrogation room immobilizes his transformed body; he cannot control its nonmetal door 25.
• Human form: Returning to flesh removes the room’s hold but also exposes him to an ordinary fall 25 26.

Potential Applications

Sheng An explains that greater knowledge of metallic elements could substantially expand his combat options. These possibilities are training goals rather than abilities already demonstrated 29.

• Switching colors and metallic compositions to suit different environments.
• Choosing soft or hard metals according to combat needs.
• Countering chemical attacks by changing composition; Sheng An names tantalum and iridium as alternatives to his original form.
• Flying through a combination of lightweight metals, magnetic fields, and teammate assistance.

Education & Training

Li Xin is intended to become a progression template for future Metal-Type Ability Users. His lessons are revised according to daily examination and training results 29.

Relationships

• Sheng An — Group B leader, recruiter, and disciplinarian. Defeats and confines him, then arranges his contract and personalized training. He alternates between calling her a villainess and appealing to her as “Sister Sheng” 23 25 26 29.
• Song Linwei — Uncle, researcher, and fellow Group B member. Initially tries to protect him through negotiation, later supports state supervision and becomes one of his physics teachers 19 27 28 29.
• Li Huai — Father. Enforces school attendance, punishes his public misconduct, and later monitors him at camp 23 24 29 30.
• Song Linlin — Mother. Alarmed by his dangerous theatrics and involved in supervising his education and well-being 21 22 25 29.
• Maternal grandparents — University teachers specializing between them in mathematics and chemistry. Their affectionate family roles give way to strict instruction during his training 22 29 30.
• Jiang Yu — Group B teammate and companion in complaints about study. Their mutual admiration survives an abrasive first encounter and turns into shared frustration with camp life 30 31.
• Hao Jingye — Helps organize his containment, testing, and employment contract, and explains how scientific knowledge affects his transformations 21 25 26 27 29.
• Unnamed girlfriend — Li Xin claims that he has a girlfriend while watching Sheng An and Qi Lingwu reunite; the admission prompts Song Linwei to take him to his parents 50.
