Stage / Realm / Level	Chapter	Notes
Evolutionist — Sonic Affinity	27–28	After absorbing a Pan-Energy Crystal, she awakens as a Manipulator. Her core ability lets her perceive unusual sounds, gather sounds, and produce high- and low-frequency waves. 27 28

Background / History

Yu Yue boards the train with her daughter, Yu Jing, after Yu Jing offers her mechanical and engineering expertise to Su Huan. Yu Jing identifies Yu Yue as a nurse capable of treating minor illnesses. From their first meeting, Yu Yue is visibly apprehensive of Su Huan and protective of her daughter. 1

Initially assigned to cook perishable food and handle dishes, she gradually becomes part of the train's logistical routine. When Carriage No. 6 is converted into a food storehouse, Su Huan appoints her warehouse manager, responsible for recording inventory and consumption. 5 13

Yu Yue also contributes practical work beyond cooking: she modifies the storage-carriage door into a reinforced three-bolt lock and helps distribute meals to workers. 17 She later evolves after absorbing a Pan-Energy Crystal, becoming the train's sound-based perception specialist. 27 28

Her sensory ability becomes vital during the Water Plant operation. She detects breathing near the team, estimates the number and location of sound sources inside the facility, and helps Su Huan avoid threats while retrieving an integrated water purifier. 34

Appearance

Yu Yue strongly resembles her daughter Yu Jing, though she has a gentler and more reserved presence. 1

• Long hair and rounded shoulders; initially wears a beige knit sweater. 1
• Pale lips and a soft, shy voice. 1
• Following evolution, her ears become more slender, higher-set, and more defined. 28
• Her skin becomes fairer, and fine wrinkles at the corners of her eyes disappear after evolving. 28

Personality

Yu Yue is timid, anxious, and frequently avoids drawing attention to herself. She is especially nervous around Su Huan, often lowering her head or trying to stay busy when he is present. 5 22 36

Despite her fearfulness, she is conscientious and useful in daily life aboard the train. She accepts responsibility for supplies, prepares meals for the group, treats Su Huan's injury, and attempts to support missions with her developing sensory powers. 13 22 33 36

Her attachment to Yu Jing remains central to her actions. She initially joins the train only alongside her daughter, worries about Yu Jing during danger, and tries to maintain composure in front of her. 1 38

Abilities & Skills

Sonic Affinity

Yu Yue's Evolutionist ability grants heightened sound perception and limited sound-wave manipulation. 28

• Can hear sound frequencies and distant noises beyond normal human perception. 28
• Can gather sounds she detects and emit high-pitched or low-frequency sounds. 28
• Her current offensive output is weak, capable of causing only brief tinnitus. 28
• Can identify threats through breathing, movement, scratching, and other sound sources. 28 34
• Estimated approximately sixty sound sources inside the Water Plant, including activity in buildings, water-tower splashing, and scratching in the guard room. 34
• Her extended perception can overwhelm her with distant sounds; Su Huan instructs her not to receive sounds from too far away and to restrain her energy dissipation. 32

Medical Knowledge

Yu Yue is a nurse who can treat minor illnesses. 1

• Brings iodine, bandages, and other supplies to treat Su Huan's venom-burned shoulder. 36
• Performs wound care after Su Huan carbonizes affected flesh to prevent venom from spreading. 36

Logistics and Domestic Work

Yu Yue manages several essential noncombat duties aboard the Armed Train.

• Records inventory and consumption as warehouse manager. 13
• Organizes supplies and handles perishable-food allocation. 22
• Reinforces Carriage No. 6's door lock with three horizontal metal bolts. 17
• Prepares meals including seafood porridge, potato-beef dishes, wontons, and river crab tofu casserole. 21 22 36 44
• Makes tofu and clothing from recovered materials. 44

Relationships

• Yu Jing — Her daughter. Yu Yue joins the train with Yu Jing, worries about her safety, and shares a close mother-daughter bond. 1 38
• Su Huan — Train captain and leader. Yu Yue follows his orders, serves as a cook and warehouse manager, and later supports his missions through medical care and sonic detection. 13 33 36
• Liang Kuan — Teammate assigned alongside Yu Yue and Su Huan during the Water Plant retrieval mission; he provides defense and support while she conducts sensory detection. 33

Story Role / Major Arcs

Joining the Armed Train

Yu Yue enters Su Huan's group through Yu Jing's recruitment arrangement, offering nursing knowledge while Yu Jing provides mechanical expertise. 1

Supply and Storage Management

She takes over cooking duties, helps maintain the train's domestic routine, and becomes manager of the food-storage carriage's inventory and consumption records. 5 13

Evolution into a Sound Manipulator

Yu Yue becomes an Evolutionist after absorbing a Pan-Energy Crystal. Her Sonic Affinity gives the Armed Train a needed perception-type capability, and Su Huan identifies her potential value as a long-range combat asset, possibly paired with a sniper rifle. 27 28

Water Plant Mission

Assigned to sensory detection during the mission to retrieve water-purification equipment, Yu Yue locates nearby threats and scouts the Water Plant's interior through sound. 33 34

White Snake Encounter

While passing the White Snake Desert River, Yu Yue becomes distressed by distant sounds of aquatic Evolutionary Beasts. Under Su Huan's guidance, she learns to limit her perception range and control the passive spread of her ability. 32

Trivia

• Yu Yue's cooking becomes a stabilizing part of daily life aboard the Armed Train, with the dining car effectively becoming her domain once Su Huan no longer has time to cook. 30
• Her Sonic Affinity causes visible physical changes, particularly to the shape and placement of her ears. 28
• Su Huan considers her sound-based ability especially suited to reconnaissance and long-range combat rather than close-quarters fighting. 28
