Background

Chu Mengxi led Zhao Tie and Li Rui to Qingyang County after the destruction of Zhang Manor exposed Moon Worship Cult activity beyond the county office's capacity. Suspicious of the case file's claims that the newly appointed Captain Lin Feng had killed a second-tier demon, she sought him out and tested his strength rather than accepting the report at face value. 15

After Lin Feng repelled Zhao Tie and Li Rui in one saber strike, she formally recruited him into the Demon Suppression Division as an Iron Token Demon Slayer and kept him on her team while the Moon Worship Cult investigation continued. 16

Appearance

Chu Mengxi is a striking young woman in her early twenties whose beauty contrasts sharply with an imposing, glacial bearing. Her phoenix-like eyes are repeatedly described as keen and cold. 15

• Wears black combat clothing and a matching black cloak. 15
• Carries a black iron Demon Suppression Division token edged with red copper, identifying her as a Bronze Token Demon Slayer. 15
• Uses a longsword and manifests icy blue sword energy in battle. 20 21
• Her inherited Ice Heart Soul pendant emits an ice-blue glow while protecting her heart meridian. 33

Personality

Chu Mengxi is disciplined, skeptical, and direct. She refuses to judge Lin Feng solely by official reports, instead demanding proof of his alleged accomplishments through combat. Even after witnessing his abnormal strength, she recognizes that he has secrets and does not press him to reveal them. 15 18

As a Demon Slayer, she places civilian protection ahead of her own safety. During the Blood Sacrifice Grand Array crisis, she immediately assigns Zhao Tie and Li Rui to protect the populace and personally heads for the array core. She continues fighting the Blood Fiend Asura despite being outmatched because thousands of civilians stand behind her. 19 21

She is also methodical in investigations. While leading the Skin-Peeling Demon task force, she identifies the victims' common traits, maps the dispersed crime scenes, and organizes simultaneous surveillance of the leading suspects. 38

Abilities & Skills

Profound Ice Sword Art

Chu Mengxi wields an ice-attributed sword art capable of producing extreme cold sword energy.

• Condenses ice crystals throughout the battlefield and lowers the surrounding temperature to freezing levels. 21
• Forms an ice-dragon-like sword strike powerful enough to freeze rivers and mountains. 21
• Freezes lesser fiends into ice sculptures before shattering them. 20
• Her ice-attributed True Qi is disadvantaged against the Blood Fiend Asura's blood-red demonic flames. 21

Demon-Slaying Combat

As a Bronze Token Demon Slayer, Chu Mengxi possesses combat ability above Zhao Tie and Li Rui and can endure large-scale battles against fiends.

• Maintains the main front during the Blood Sacrifice Grand Array incident while her subordinates are overwhelmed. 20
• Severed two of the Blood Fiend Asura's arms and inflicted multiple sword wounds, though the demon regenerated through blood energy. 21
• Remained defiant while captured by the Old Demon of Black Wind, despite having her True Qi continuously drained. 33

Investigation and Command

Chu Mengxi leads field operations with a focus on evidence, threat assessment, and coordinated deployment.

• Tested Lin Feng's strength before deciding whether to trust the Qingyang County case report. 15
• Directed the response to the Blood Soul Grudge Array, assigning civilian protection and array-core investigation simultaneously. 19
• Led the special task force investigating the Skin-Peeling Demon. 38
• Conducted three days and nights of surveillance on Ink Rhyme Studio, though the suspect escaped her pursuit. 39

Relationships

• Old Demon of Black Wind — Captor who attempts to drain her supremely yin True Qi to advance into the Dan Yuan Realm. 33
• Li Bantian — Confronts her and the Demon Suppression Division while accusing Lin Feng of murdering his son, Li Tianyu. 44

Story Role / Major Arcs

Qingyang County and the Blood Sacrifice Grand Array

Chu Mengxi arrives in Qingyang County to investigate the Moon Worship Cult and Lin Feng's suspiciously extraordinary record. She recruits Lin Feng after his overwhelming display against Zhao Tie and Li Rui. 15 16

When the Blood Soul Grudge Array traps the county and turns citizens into Walking Corpses, she orders Zhao Tie and Li Rui to defend civilians while she moves against the main array core. She confronts the newly born Blood Fiend Asura alone, suffers severe injuries, and is saved after Lin Feng destroys the demon. 19 21 22

Transfer to Nan Yan Commandery

After Qingyang County is saved, Chu Mengxi offers Lin Feng a place in her Seventh Demon Slaying Squad at the Nan Yan Commandery headquarters. She continues to guide him within the Demon Suppression Division and warns him of the risks of the Weeping Ghost Mine mission, giving him a Calm Heart Pill. 22 24

Black Wind City Rescue

Chu Mengxi leads a three-star investigation into Black Wind City but is captured after the mission encounters an opponent believed to be at Half-step Dan Yuan Realm. Bound by black iron chains, she resists the Old Demon of Black Wind's attempts to drain her True Qi, with the Ice Heart Soul preserving her life. 30 33

She throws the Ice Heart Soul to Lin Feng during the final battle, allowing him to use its transformed ice sword to annihilate the Old Demon. Exhausted and depleted, she faints after thanking him. 34

Skin-Peeling Demon Investigation

After recovering, Chu Mengxi leads the special task force investigating a Skin-Peeling Demon preying upon young women in Nan Yan Commandery. She initially objects to using Ling Yue'er as bait, but works with Lin Feng, Zhao Tie, and Li Rui to protect her during the operation. 37 38 39
