After My Secret Identity Was Exposed, My Wicked Disciple Went Completely Mad

(Two powerful leads + past and present lives + female master and male disciple + one-on-one, both chaste) The cool and aloof master Feng Qingling, born with bewitching beauty, and her sweet-looking but scheming, ruthless little disciple, Gu Nianqing. Everyone says that ten thousand years ago, the Divine Maiden Linghuang of the God Realm and the Night-Devouring Demon Lord were sworn enemies. During the war between gods and demons, the Divine Maiden Linghuang mercilessly slew the Night-Devouring Demon Lord with her sword. The demons lost the war, and from then on were trapped in the spirit-poor Demon Realm, never to leave. The God Realm also suffered heavy losses, and the gods nearly vanished. After slaying the Heaven-Devouring Demon Lord, the Divine Maiden Linghuang disappeared without a trace. Ten thousand years later, the only divine phoenix in all the heavens and earth is born. She disguises herself as a boy from childhood to hide her secret, but after taking a little disciple, her disguise is exposed. A little scene: Little Disciple: “So Master is a woman! You really had me fooled!” Feng Qingling watches her disciple approach with a smile. No, she should say the Demon Lord now. For some reason, she feels a little nervous. Feng Qingling: “Disciple, let your master explain.” Little Disciple: “Heh. And what if I don't want to listen?” Feng Qingling's inner thoughts: This venerable one... Why are my legs going weak!!!??
