Yan Jue transmigrated into a fantasy novel as a fox spirit—a cannon fodder villainess who must seduce the male lead and absorb his yang energy to cultivate. The female lead, Qi Xianqing, is the revered senior sister of Zhenhuo Sect, a demon-slaying prodigy untouched by mortal desires. Yan Jue knows all too well the fate of those who vie for the male lead’s affection. In the original plot, the cold and ruthless Qi Xianqing runs her through with a sword, rips out her heart, and hands it over to the alchemy division. She was practically designed as a training dummy for the protagonists—dead before Chapter 10. Thus, Yan Jue devises a foolproof plan: stick close to Qi Xianqing to gain experience, then flee once she’s strong enough. But Yan Jue soon discovers Qi Xianqing’s rare Immortal Spirit Physique—her blood is lethally irresistible to demons. Every time Yan Jue sees her, her legs weaken, and she desperately wants to cling to Qi Xianqing and sniff her. When Yan Jue finally prepares to leave, the aloof senior sister approaches her. Legs giving out, Yan Jue is caught in Qi Xianqing’s embrace. Qi Xianqing strokes her accidentally exposed fox ears and murmurs, “Don’t go, alright?” — Fate has other plans. By day, Yan Jue appears human; by night, she reverts to her fox form. One evening, while strolling near a spiritual spring, she encounters Qi Xianqing training. Yan Jue freezes, fur standing on end, about to bolt— When Qi Xianqing suddenly crouches, holding out a bone with a smile. “Come here.” Who would’ve guessed the ethereal senior sister, untouchable as a celestial, adores fluffy creatures? Under the moonlight, she chats with a little fox by the spring. Unintentionally, Yan Jue learns too many secrets. By day, Qi Xianqing and the male lead are the sect’s golden couple. By night, Qi Xianqing sighs, petting Yan Jue’s head. “We barely interacted. I don’t know why he clings to me.” “…” By day, Qi Xianqing raids a millennium-old pangolin demon’s den, indifferent to its orphaned pups. By night, she cuddles the fox, murmuring, “I shouldn’t have destroyed its nest. It takes three years to rebuild… Those babies will starve.” “…” By day, Qi Xianqing scorns Yan Jue, shoving her away. By night, she frets, stroking the fox’s ears. “There’s a junior named Yan… I think I like her.” Yan Jue: “?” *This fox understands nothing.* One day, Yan Jue gets drunk and reveals her fox ears. She tries to flee—only for Qi Xianqing to yank her back by the collar. Expression icy, Qi Xianqing says, “Know my secrets and still think to run?” Yan Jue whimpers, “Senior Sister, I’ll repay with my life…” Qi Xianqing smirks, fondling her ears. “No need. Just stay by my side.” — Qi Xianqing lives by one creed: slay demons without mercy. Countless have fallen to her blade, yet she’s never hesitated. Until this one fox spirit ensnared her. She once scorned emperors bewitched by foxes. Now, she’d gladly drown in tenderness—spoiling, loving, even walking through fire for her.
