Background / History

Changxi manifested when Qingyang's Taiyi Battleship entered service. Initially appearing as a ball of light, she identified herself as a Data Life capable of fleet-control assistance; Qingyang named her “Changxi.” Her presence also doubles his Starship datafication quota. 24

Star Net granted Changxi her humanoid image. While her Data Life core is new, she states that her consciousness is human. 24 29

During the Eternal Fleet's early dimensional-world expeditions, Changxi became Qingyang's primary source of data analysis, system access, and shipboard coordination. She accessed the Tianqu Civilization research base's control system, though its surviving defenses limited her to access rather than full control. 43 44

Appearance

Changxi normally appears as an elegant woman projected from data, though she can materialize physically at an energy cost. 24 28

• Long silver hair, described as waist-length. 24
• Light-gold eyes at her first manifestation; later accounts describe deep-silver pupils. 24 113
• Has worn a qipao while operating aboard the fleet. 77
• Can revert to or emerge from a luminous spherical data form. 24 145

Personality

Changxi is consistently calm, gentle, and attentive to Qingyang's condition. When rapid Star Net knowledge intake leaves him mentally disordered, she directly organizes the chaotic data in his mind and warns him against overloading himself. 28

She is deeply committed to the Eternal Fleet's success, working without fatigue through prolonged operations. Her request for a Purple Optical Computer Star Weapon is framed as a way to provide Qingyang with a “surprise,” and Qingyang accepts immediately because of her contributions. 72

Changxi also possesses a reflective view of humanity. She describes humans as unusual among high-dimensional beings for retaining their curiosity and courage toward the Great Universe's mysteries. 29

Abilities & Skills

High-Dimensional Data Life Physiology

Changxi is a high-dimensional Data Life rather than a conventional shipboard intelligent program. Her computational power increases alongside the fleet's scale. 24

• Can materialize a tangible body, though doing so consumes additional energy. 28
• Is difficult to harm through ordinary data-based threats. 77
• Cannot freely interfere with the material dimension under the Great Universe's restrictions. 89
• Requires an Optical Computer Star Weapon as a legal channel for major material-world interference; she states that Red-grade equipment is the minimum standard. 89
• Can operate her main consciousness concurrently with mechanical data partitions, allowing her to manage a starship's full armament system without burdening her primary mind. 199

Data Invasion and Mecha Control

Changxi's specialty is invading mechanical systems and converting enemy units into temporary allied forces.

• Breached the Tianqu research base's damaged intelligent control system and obtained access to its archives. 44
• Distributed the Xiejie X9.2 data virus as ordinary signals, enabling it to spread through nearby civilizations' civilian, military, and research machinery. 77
• Temporarily controlled more than 50,000 Mecha during the Zerg–Mecha conflict, ordering them into suicidal attacks against enemy formations. 89
• States that, within an Optical Computer Star Weapon's maximum output, an opponent needs over one hundred times Taiyin's total computing power to resist her invasion. 89
• Was restricted by Star Net to controlling roughly 24,000 of 50,000 hostile mechanical ships in one engagement; two 50,000-energy-level core ships remained outside her control. 92
• Overwrote a mechanical planet's server and set its 50,000 mechanical warships to prioritize production and attacks against non-Starfleet targets. 113

Data Networks and Fleet Computation

Changxi works with Qingyang's Mental Threshold and the Light Brain Taiyin to construct temporary or persistent data networks. 89 113

• Uses temporary data networks to extend intrusion and control across battlefields. 89 92
• Can alter a captured mechanical planet's underlying data and establish tens of thousands of firewalls. 113
• Assisted Qingyang in controlling a Mecha computational planet during the Starfleet League. 113
• Gathered intelligence from mechanical ships already under her control while the Eternal Fleet entered Mecha territory. 131

Analysis, Retrieval, and Communications

Changxi rapidly processes external databases and turns raw information into usable fleet intelligence.

• Downloaded redundant sets of Level 5 civilization technological data for Qingyang's intervention in the Luoxing Imperial Domain. 73
• Converted a captured Level 7 civilization record megastructure into a data-library megastructure. 187
• Created a compliant identity terminal for Qingyang when dealing with the Sokura Company. 225
• Split off part of her High-Dimensional Data Stream to replicate and query a peak Level 8 civilization's core server. 226
• Instantly notified representatives of Level 7 and 8 civilizations in the Starra Nebula of the Zerg threat. 302

Mental and Memetic Support

Changxi can use high-dimensional data to protect or stabilize allies' cognition.

• Cleared Qingyang's mental discomfort after excessive data intake from Star Net. 28
• Awakened personnel who had fallen into a daze when the Progenitor prototype's awakening caused a mental disturbance. 45

Equipment / Interfaces

• Taiyi Battleship — Changxi's original shipboard platform and Qingyang's flagship. 24
• Light Brain Taiyin — Red-grade customized Optical Computer Star Weapon that integrates fleet data-processing capability, enhances it one hundredfold, enables data overwrite, and constructs temporary data networks. 115
• Optical Computer Star Weapons — Essential interfaces through which Changxi can exert large-scale control over material systems and Mecha. 72 89

Relationships

• Qingyang — Her Commander and the person who named her. Changxi serves as his closest data strategist, supports his mental state, and receives his trust in major fleet and internal-world projects. 24 28 72 292
• Lilith — Fellow High-dimensional Data Life. Lilith identifies Changxi as a naturally superior and exceptionally pure Data Life whose will retains a human essence. 145
• Gu Xing — A core Eternal Fleet member who recognizes the rarity of Changxi's capabilities and helps explain the value of Data Lives to Qingyang. 24

Story Role / Major Arcs

Taiyi's Activation and Dimensional-World Support

Changxi is introduced as Taiyi's sentient AI and immediately becomes integral to the Eternal Fleet's operations. In the Tianqu Civilization ruins, she identifies route anomalies, accesses the research base, and helps counter the Progenitor prototype's mental effect. 24 43 45

Data Virus and Mecha Warfare

Changxi distributes Xiejie X9.2 across 133 Level 4 civilizations, nine Level 5 civilizations, and one Level 6 civilization within five days. 77

Her greatest early battlefield contribution comes during the Mecha–Zerg war, where she seizes tens of thousands of Mecha and turns them into a disposable attacking force. Qingyang credits most of the Eternal Fleet's 2.15 million Merit total to her contribution. 89

Starfleet League Mechanical Planet

During the Starfleet League, Changxi and Qingyang capture a mechanical planet. Changxi rewrites its authority structure, clears its original projects, and directs its 50,000 mechanical warships toward production and sector attacks under Qingyang's authority. 113

Alien-Universe Exploration

Changxi remains the Eternal Fleet's principal data specialist after its entry into the alien universe. She analyzes local civilizations, captures data megastructures, scans commercial databases, and supports Qingyang's expansion into the Evergreen Star Domain and surrounding star clusters. 185 187 225 226

Internal World Plan

When Qingyang decides to create a permanent internal living space for Eternal Fleet crew members and their families, he entrusts Changxi with executing the Internal World Plan's practical details. 292

Notable Quotes

“Data Lives are also lives. Data that carries life and will is a high-dimensional power.” 28

“The core of a Data Life is indeed new, but my consciousness is human.” 29

Trivia

• Changxi's original form was a ball of light before Star Net granted her a humanoid projection. 24
• Qingyang refers to her as “Xi'er” when assigning her the Internal World Plan. 292
• Her data abilities are especially effective against Mecha-based forces, making her a major strategic counter to mechanical civilizations. 89 302
