Background

Cheng Xiaoyu is the wealthy son of a Flying Cloud City gym owner. His family operates seven gyms, and his status gives him unrestricted access to facilities such as the Gravity Rooms. He initially appears proud, enjoys admiration, and is surrounded by classmates hoping to benefit from his wealth and advanced equipment 32 34.

As a first-year Mecha Department student, Cheng builds the Silver-Armored Warrior, an expensive silver humanoid mech equipped with twin blades and high-grade Superalloy armor. Fu Junlin publicly identifies a hidden flaw in its lumbar power structure, but Cheng rejects the warning rather than allow an unfamiliar student access to his mech 34 35.

The flaw manifests during Cheng’s best-of-three mecha duel with Wang Jintang. Forced to seek Fu’s help, Cheng accepts a deal: Fu repairs the mech in exchange for access to the gym’s Gravity Room. Fu’s rapid repair allows Cheng to defeat Wang and win their 100,000-yuan wager, beginning their close friendship 37 38 40 42.

Appearance

Cheng is regarded by his peers as handsome and is frequently dressed in expensive casual clothing as a wealthy heir 36 78.

• Operates silver humanoid mechs and later a custom mechanical lower body.
• Uses a wheelchair when conserving energy or when his leg armor is impractical 257.
• After losing his lower legs, relies on Soft Alloy exoskeleton systems that can shift between walking armor, thruster legs, and wheelchair configurations 246 274 375.
• His Mantis Arm manifests as an invisible defensive field around his body or projected across a wide area 334 417.

Personality

Cheng begins as a status-conscious young master who enjoys praise, but he dislikes insincere followers and favors direct, transactional honesty. Fu Junlin’s refusal to flatter him earns his respect, especially after Fu proves his technical judgment by repairing the Silver-Armored Warrior 38 39.

He is impulsive, loud, and fond of showing off, yet his confidence is paired with unusual loyalty. He publicly confronts his uncle to honor his promise to Fu, then claims a Gravity Room for Subspecies use rather than accept racial exclusion at his family’s gym 45 46.

After becoming paralyzed, Cheng adopts a “live in the moment” outlook. He spends resources freely on survival and training, refuses to abandon the battlefield, and treats his disability as a problem to engineer around rather than a reason to withdraw 249 261 278.

Abilities & Skills

Mecha Mastery

Cheng is a trained Mecha Master capable of controlling humanoid combat machines through cerebral and finger-mounted controllers.

• Pilots the Silver-Armored Warrior with synchronized twin-blade attacks, armored defense, and hydraulic-leg maneuvers 36 37.
• Uses heavy armor suits as mobile shields and anchors for Qiao Zishu’s sniper fire 282 377.
• Develops increasingly advanced prosthetic lower-body systems after his paralysis, including walking, jumping, and thruster functions 274 278.
• Experiences a later breakthrough in mech manufacturing, producing a fully redesigned mechanical lower body with hybrid power and intelligent assistance 515.

Mantis Arm

The Mantis Arm is an invisible defensive energy field acquired after Cheng absorbs defensive energy released by a missile.

• Initially forms an autonomous barrier roughly half a meter around him and reacts violently even to allies 334.
• Can compress, twist, redirect, or throw back incoming objects with immense torsional force 334.
• Becomes controllable after Cheng links himself to the shield’s primitive defensive intent through repeated combat with Fu Junlin 355.
• Protects both Cheng and Qiao Zishu from Jie's compressed-energy bullets during their duel 376 377.
• Can be extended over several kilometers to block large-scale projectile attacks 417.
• Requires substantial energy expenditure during wide-area defense; Cheng absorbs Energy Crystal Blocks directly to sustain it 417.

Defensive Combat

Cheng specializes in holding positions, absorbing attacks, and protecting teammates.

• Used his mech and body to shield Qiao Zishu from Jie’s shot, sustaining the spinal injury that paralyzed him 236.
• Intercepted a second missile after Fu Junlin was occupied neutralizing the first, acting with the expectation that he might die 332 333.
• Anchors himself with massive mechanical armor when receiving high-impact attacks through the Mantis Arm 377.
• Favors defense and mechanical firepower over direct offensive martial combat 316.

Equipment

• Silver-Armored Warrior — A silver humanoid mech made with 2.4 Superalloy armor, twin blades, and a hydraulic telescoping leg. Its flawed X-shaped support system was rebuilt into a reinforced umbrella-rib structure by Fu Junlin 35 40.
• Soft Alloy exoskeleton — Fu Junlin’s first-generation lower-body armor for Cheng; supports his legs during the day and converts into an accelerated wheelchair 246.
• Mechanical lower-body armor — Later upgrades provide walking, running, jumping, thruster movement, and heavy-armor transformations 274 375.
• Heavy armor suits — Two large defensive armors used for battlefield protection, missile interception, and stabilizing the Mantis Arm under heavy fire 282 332 377.
• Black Card — A family-gym membership card Cheng gives Fu Junlin, granting access to all facilities and becoming the source of their dispute over Subspecies access to the Gravity Room 42 43.

Relationships

• Fu Junlin — Close friend, technical partner, and fellow fighter. Fu repairs Cheng’s first major mech, builds his mobility armor, and helps him establish control over Mantis Arm; Cheng supports Fu’s business ventures and repeatedly risks himself for him 40 114 246 355.
• Qiao Zishu — Wife and combat partner. Cheng shields her in battle, while Qiao supports him through his paralysis and works alongside him as the primary attacker behind his defenses 236 246 375 376.
• Wang Jintang — Mecha rival. Cheng defeats Wang after Fu repairs the Silver-Armored Warrior, winning their 100,000-yuan wager and intensifying Wang’s hostility toward Fu 36 42.
• Jie — Enemy who shattered Cheng’s spine. Cheng later challenges him to a turn-based duel, survives Jie's Roar of Steel, and spares him because Jie had previously spared someone Cheng loved 236 375 378.
• Cheng Xiaoyu’s uncle — Gym manager and antagonist in the Gravity Room dispute. His attempt to bar Fu from the facility exposes his prejudice against Subspecies and corruption within the business 43 45 46.
• Commander Viper — Military commander who recognizes Cheng’s courage, credits his missile interception, and encourages his continued adaptation to combat service 278 343.

Story Role / Major Arcs

Silver-Armored Warrior Duel

Cheng’s rivalry with Wang Jintang leads to a high-stakes mecha battle. His first victory is nearly undone by a structural failure predicted by Fu Junlin, forcing Cheng to overcome his pride and seek help. Fu’s repair enables Cheng to win the rematch and establishes their friendship 36 42.

Subspecies-Only Gravity Room

After Cheng’s uncle refuses Fu Junlin access to the Gravity Room because he is a Subspecies, Cheng publicly challenges the discrimination. He claims one of the gym’s three Gravity Rooms and designates it “Subspecies Only!”, turning a private promise into a public equality statement 45 46.

Soft Alloy and Water-Plant Partnership

Cheng becomes Fu’s business partner in marketing Soft Alloy, identifying industrial applications and urging Fu not to undervalue the material. Later, he is entrusted with overseeing his family’s water-processing project in Crimson Crown City after learning of his father’s enormous reconstruction investment 114 249 273.

Flying Cloud City Disaster

During the destruction of Flying Cloud City, Cheng uses his mech and body to intercept a bullet aimed at Qiao Zishu. The attack tears through his chest and spine, leaving his lower body permanently paralyzed; his survival and Qiao’s devotion become a turning point in their relationship 236 246.

Recovery and Expedition Service

Rather than retire, Cheng adapts to exoskeleton armor and returns to training with Fu Junlin. He joins the Fifth Expedition Team, improves his mechanical mobility, and gradually regains combat usefulness despite the loss of his legs 249 269 278.

Missile Interception and Mantis Arm

When a second missile launches during an expedition, Cheng drives himself into it to protect the group. The resulting energy becomes Mantis Arm, a powerful defensive field that later develops into one of the team’s defining battlefield abilities 332 335 355.

Duel with Jie

Cheng and Qiao confront Jie, the man responsible for Cheng’s paralysis. Cheng proposes a turn-based shooting duel, defends Qiao against Jie's attacks, and survives the final Roar of Steel by betting his conviction on Mantis Arm’s protection. He ultimately spares Jie rather than kill him in revenge 375 378.

Later Military Service

Cheng uses Mantis Arm to break a Javelin Ghoul siege by exposing the enemy force for allied counterattack. Following later energy absorption, his talent develops toward advanced mech manufacturing, allowing him to build increasingly refined mechanical bodies for himself 417 515 516.
