Cang Leng

Biodata

Power Progression

Appearance

• Normal appearance: Purple hair and smoky gray-purple eyes, described as misty or hazy 2 9.
• Partially mutated appearance: Glossy fish scales cover his arms, his ears become translucent purple fins, and his pupils shift between innocent-looking circles and seductive slits. His upper body eventually takes on more extensive merfolk features 10 11.
• Spirit Body: A pale-purple mermaid approximately matching his height and build, with scaled arms and tail, elaborate patterns across its upper-body muscles, and more pronounced mermaid features than Cang Leng himself 13.

Personality

Cang Leng initially appears dreamy and curious: merely seeing Xin Lan’s photograph makes him wonder whether he has fallen in love at first sight. When competing for her approval, however, he is direct and sexually uninhibited. He recognizes that he cannot rival Chi Ming’s attentiveness and instead tries to distinguish himself through his merfolk traits 2 10 11.

His apparent innocence can conceal calculated provocation. After Xin Lan accepts his Spirit Body as a sleeping companion, he repeatedly needles Chi Ming about jealousy and the supposed superiority of a mermaid over a snake. Once Chi Ming punches him, Cang Leng runs to Xin Lan in tears and presents himself as the injured party; Chi Ming realizes that the confrontation was deliberately engineered 13 14.

Xin Lan’s punishment strengthens rather than discourages his attachment. He responds with reverence, thanks her for disciplining him, and insists that her mental power has left his landscape cleaner and his Spirit Body calmer. Despite this exaggerated devotion, he can become serious and analytical when discussing her abilities 12 14.

Abilities & Skills

Partial Merfolk Mutation

Cang Leng can remain rational during a partial mutation, although doing so costs him some human emotions 11.

• Voluntarily releases his suppression to manifest scales, fins, and other merfolk characteristics 10 11.
• Easily removes Wu Xi’s hand when Wu Xi attempts to silence him 11.
• Alarms the other sentinels because mutation normally signals an approaching loss of reason 11.
• Cannot maintain the transformation against Xin Lan’s mental attack 11.

Merfolk Charm

His transformed voice carries a passive, enticing quality compared to a siren’s whisper 11.

• Works on humans, particularly those with weak willpower and strong sexual desire 11.
• Has no effect on contaminants or other species 11.
• Fails to secure Xin Lan’s compliance: she allows him to approach before slapping him and attacking his Mental Landscape 11.

Mermaid Spirit Body

His Spirit Body possesses a distinct mind while sharing his five senses 11.

• Sensory feedback: Cang Leng feels Xin Lan touching its ear fins and holding it 13.
• Cooling contact: Its scaled arms and tail remain cool, allowing it to function as a body pillow without overheating her 13.
• Humanoid form: It can hold Xin Lan in return while she embraces it 13.
• Separate disposition: It behaves docilely despite Cang Leng’s much more demonstrative excitement 13.

Sentinel Combat

Cang Leng is a high-level sentinel capable of participating in destructive close-quarters combat 30.

• Joins Wu Xi and Yun Jin in fighting Chi Ming, though the three struggle against Chi Ming after his purification 30.
• Undertakes missions alongside Yun Jin 39.
• Suffers headaches and poor sleep when his Rampage Level is high; sustained fighting can aggravate his condition 30 36.

Story Role / Major Arcs

Matching with Xin Lan

The Star Brain identifies Cang Leng as one of five sentinels with 99.99% compatibility with the newly registered Xin Lan. Fascinated by her photograph, he suspects that he has already fallen in love. When he later meets her at the Sanctuary, her indifference toward administrator Mo Xiao surprises him, and her closeness to Chi Ming draws his attention 2 9.

Failed Seduction and Mental Punishment

Asked to present his advantages as a prospective exclusive sentinel, Cang Leng partially mutates and attempts to charm Xin Lan. He ignores the others’ warnings, believing he can control himself and that his approach is succeeding. Xin Lan instead slaps him and attacks his Mental Landscape for five minutes, forcing him back to normal and leaving him crawling to her feet to apologize 10 11.

He subsequently admits that using his mutation’s abilities to bewitch her was wrong. Rather than fearing her, he thanks her and claims that the punishment also purified him. Xin Lan denies having deliberately provided that benefit 12.

Spirit Body Acceptance and Testing

Cang Leng gains permission to stay with Xin Lan by offering his mermaid Spirit Body as a cool sleeping companion. His ensuing attempt to provoke Chi Ming ends badly: after their dispute interrupts her nap, Xin Lan orders them to exchange punches and briefly attacks both Mental Landscapes 13 14.

Testing afterward confirms that Cang Leng’s Rampage Level has fallen to 89%. He and Chi Ming conclude that Xin Lan’s power can attack while also providing purification and soothing, and Cang Leng suspects that her actual rank exceeds S 14.

Competition Within the Household

Xin Lan later instructs Mo Xiao to arrange for Cang Leng and the other sentinels to move into the Sanctuary. Cang Leng continues competing for her attention, but Chi Ming and Wu Xi obtain sleeping privileges that he has not received. Their success intensifies his jealousy, especially while he remains troubled by headaches and sleeplessness 28 36 42 45.

He also joins the others in resisting Mo Xiao’s advances. When Mo Xiao asks to call Xin Lan “Baby,” Cang Leng objects and warns that the administrator is exceptionally scheming. Xin Lan ultimately tells Mo Xiao to use her name instead 47.

Relationships

• Xin Lan — His 99.99%-compatible guide match and the object of his devotion. She rejects his attempt at mental seduction but accepts his mermaid Spirit Body as a sleeping companion. He remains eager to become her exclusive sentinel 2 11 12 13 22.
• Chi Ming — A principal rival for Xin Lan’s favor. Cang Leng deliberately provokes him, but the two also cooperate in investigating Xin Lan’s mental power and stopping Wu Xi from interrupting her private call 13 14 40.
• Wu Xi — A fellow suitor whom Cang Leng treats as a potential ally against Chi Ming. Wu Xi denies ever agreeing to that alliance, and his growing intimacy with Xin Lan leaves Cang Leng feeling betrayed and envious 36 39 40 45.
• Yun Jin — A fellow sentinel and mission partner. Yun Jin tries to stop his mutation and checks on him after Xin Lan’s punishment; they later share their frustration over being overlooked 11 39 45.
• Mo Xiao — K9 District’s administrator and another romantic rival. Cang Leng shares his observations about Xin Lan’s power with him but later openly criticizes his political maneuvering 14 47.
