The Good-for-Nothing Junior Sister Is Actually the Demon Venerable's One True Love

The junior sister, newly arrived at the sect, is sweet, naive, and delicate, cherished by everyone in the immortal sect.

Until the Demon Venerable breaks through the formation, his oppressive aura forcing every disciple to their knees.

Only the junior sister, who had been dozing, wakes with a start and sleepily tugs at the Demon Venerable's sleeve. “I'm sleepy. Carry me.”

The disciples are about to stop her, but the demon who kills without blinking crouches down. “All right. I'll take you home.”

A thousand years of scheming, and it turns out he never slaughtered the immortal sect for revenge against his enemies:

He was searching for the bright moon he had lost.
