After Being Bound by a Dual-Cultivation Pact to the Demon Lord

The demon Ying Xi has spent over a decade undercover among the orthodox sects, all for the chance to sneak into the Ghost Abyss one day and reclaim the power that belongs to him. After waiting so long for a once-in-a-thousand-years opportunity to regain his true form, everything is ruined by Zhi Xueshi, who drops out of the sky. The two of them are also bound by a dual cultivation pact that flares up at unpredictable times. The demon grits his teeth. "...I hate this!" - Zhi Xueshi transmigrates into a book, becoming an Outer Sect disciple of the Kunshan Sword Sect. She unexpectedly discovers that the great demon she made a pact with is none other than the sect's celebrated genius swordsman, the lofty and untouchable Senior Brother! Zhi Xueshi trembles in fear. Though they seem to have nothing to do with each other in public, the two often meet in secret. During the sect's disciple tournament, the dual cultivation pact suddenly flares up. Zhi Xueshi sneaks off during the break, and the demon gets up and leaves, too. They both make their way to the secluded back mountain. Zhi Xueshi loosens her belt and sighs. "Hurry up. I have to get back onstage later." Before leaving, the demon tosses her a huge pile of high-grade pills, magical artifacts, and talismans. Zhi Xueshi, who has never been this rich in her life, lights up. "Thanks, boss!" The youth turns his back to her, the redness at the corners of his eyes not yet faded. His voice is cold and hard. "If you dare get expelled from the sect, you're dead." - Later, Zhi Xueshi is taken in by the sect leader and becomes the great demon's junior sister. Her master orders Ying Xi to teach her swordsmanship, and Ying Xi agrees with obvious reluctance. Their fellow disciples say the two can't stand each other: one refuses to teach, the other refuses to learn, and they're at each other's throats all day long. One morning, someone practicing swordsmanship sees Zhi Xueshi run out of Senior Brother's cave abode with her clothes in disarray. Zhi Xueshi thinks, I'm done for. They'll figure it out. But the next day, she hears a rumor: "Junior Sister and Senior Brother really don't get along. They argue during the day, then sneak off to Senior Brother's cave abode at night to fight. They fought all night..." Zhi Xueshi: ... - When they first met at the sect, the demon took Zhi Xueshi somewhere deserted and threatened her fiercely. "Don't tell anyone who I am, or else..." Zhi Xueshi nodded like a bobblehead and swore she would never tell. But later, after one of their secret meetings, Zhi Xueshi puts on her clothes and is about to sneak out of his cave abode when someone grabs her from behind. The youth's long fingers twirl a strand of her hair. He buries his chin in the hollow of her shoulder and says lazily, "Panpan, when are we holding our bond-ceremony?" Zhi Xueshi: !!! When did she ever agree to marry him? 1. A lighthearted, sweet story. The heroine's nickname is Panpan. 2. A cultivation maniac who's all about training and a little clueless x an unpredictable, love-struck great demon 3. The blurb was screenshotted on June 29. Don't claim I copied yours.
