Background / History

He Xi first appears discussing Wang Ji with Holy Keisha from afar. Intrigued by his ambition, unconventional weapons, and unclear origins, she argues that Leina and Earth’s researchers underestimate his real capabilities. She proposes visiting him, while Keisha advises patience because of Wang Ji’s caution. 109

She later meets Wang Ji directly and becomes one of the first Angels to identify the principles behind his unusual equipment. Through demonstrations to her disciple Zhi Xin, He Xi explains how a Sub-Biological Engine can redefine an object’s physical properties, using strengthened frying pans and firearms as examples of Wang Ji’s innovations. 161 169 171

He Xi begins secretly teaching Wang Ji space-time technology and broader knowledge of the universe. Their teacher-student relationship is complicated by her effort to understand his abilities and obtain information without revealing the Angels’ full motives. 196 214 215

When Wang Ji uses a Void Engine to enhance ordinary humans, He Xi is assigned to explain that the practice violates Keisha’s Justice Laws. She sympathizes with his need to protect and sustain his soldiers, but remains bound to represent the Angels’ opposition to unrestricted human enhancement. 215 216 219

Her initially guarded relationship with Wang Ji becomes personal. Keisha repeatedly teases He Xi over her interest in him; He Xi admits his excellence but cites their age difference and her “sealed heart” as reasons not to pursue him. She eventually confesses regret over treating him as an object of calculation rather than speaking honestly about her feelings. 207 208 306

During Wang Ji’s visit to Angel City, He Xi becomes deeply attached to Xiao Nai Sha, recognizing her resemblance to Keisha and volunteering to care for her. She later accepts Xiao Nai Sha’s true identity and helps integrate her into Angel City. 368 369 373

As larger conflicts escalate, He Xi continues research crucial to Wang Ji’s side, including work on Void Particles accelerated with additional resources. She also participates in Angel City and Heavenly Court political discussions after Wang Ji’s rise in status. 391 417

Appearance

He Xi is an Angel woman with silver hair and deep blue, star-like eyes. Her appearance is repeatedly described as exceptionally beautiful, combining an elegant, intellectual bearing with a refined and alluring presence. 109 159

• Silver hair described as moonlike or luminous. 109 159
• Sea-blue, starry eyes. 109 306
• Commonly wears a silver gauze dress or veil. 109 187 422
• Has also appeared in silver armor, a cape, and formal military attire. 161 242 306
• Favors pink lipstick and pink nail polish despite Wang Ji teasing her for the youthful color. 161

Personality

He Xi is analytical, perceptive, and technologically curious. She rapidly identifies patterns in Wang Ji’s abilities that Earth’s researchers fail to understand, then follows those clues through experimentation and study. 109 170 214

She is confident and teasing in conversation, particularly with Wang Ji and Keisha. Her banter often conceals serious strategic thinking, and she is willing to soften her approach when direct probing fails to produce results. 159 209

Despite her status and age, He Xi is emotionally vulnerable concerning Wang Ji. She resents being manipulated by Keisha into teaching him, fears being seen as calculating, and later openly regrets withholding her feelings. 207 306

Her conduct toward Xiao Nai Sha reveals a gentle, maternal side. She is attentive to the child’s comfort, health, and adjustment to Angel City, and seeks to raise her as her own. 369 370

Abilities & Skills

Technological Analysis and Engineering

He Xi is a leading Angel researcher with broad expertise in advanced materials, genetic engineering, weapons, and Void-related sciences.

• Analyzes Wang Ji’s enhanced frying pans and firearms as applications of conceptual redefinition through a Sub-Biological Engine. 171
• Replicates a frying-pan design after studying its unconventional principles. 170
• Researches the use of Sub-Biological Engines to elevate ordinary soldiers to a level comparable with low-level beast-type Super Soldiers. 215
• Understands the limitations of such enhancement, including the Angels’ ethical and legal restrictions on rewriting ordinary human physical data. 216
• Conducts research into Void Particles, a project Wang Ji later accelerates with added resources. 391

Space-Time Technology

He Xi possesses advanced knowledge of space-time systems and teaches Wang Ji about the wider universe, civilizations, and space-time technology. 196

• Explains and discusses Space Imprisonment technology, knowledge Wang Ji later recalls during a Demon ambush. 203
• Detects unusual spatial intrusion data around Angel City and recognizes that it does not resemble ordinary material-plane or Dark Dimension spatial technology. 367 368
• Uses and understands Wormhole travel at a level far beyond conventional aerospace technology. 211

Strategic Assessment

He Xi evaluates threats through long-term technological and political consequences rather than immediate appearances.

• Recognizes Wang Ji’s potential to become a major power before his full strength is known. 109
• Helps reconstruct Wang Ji’s rapid rise from a single Sub-Biological ability into a force with Super Genes, fleets, soldiers, and a developing civilization. 221
• Considers the interstellar consequences of the Taotie fleet’s destruction and questions whether Wang Ji could be responsible. 229

Equipment / Weapons / Items

• Silver Blade — carried during her first shown meeting with Wang Ji, when she holds it at his neck. 161
• Dark Alloy armor and computing cluster — provides He Xi with substantial independent computational support. 243
• Modified frying pans and firearm — experimental weapons used to demonstrate Sub-Biological Engine enhancement principles. 169 171
• Star Destiny — her unique Angel weapon, bestowed by Keisha; it is identified as the sole Star Destiny held by the Angel race. 377

Relationships

• Holy Keisha — Queen, longtime confidante, and frequent source of exasperation. Keisha assigns He Xi to study and teach Wang Ji, then repeatedly teases her about her growing feelings for him. 109 207 208
