I Transmigrated into a Book as Cannon Fodder for the Demonic Sect, but Became the Tsundere Sect Master's Inner Demon

[Ding! Favorability System successfully bound.]

What? The stunning sect master is marrying me today?

Huh? She wants me to experience the wonders of dual cultivation?

Oh, so I'm born with a sacred dual-cultivation physique!

Well, that's great... Wait, why are there so many women? The Holy Maiden of the Dual Cultivation Sect, the fairy of Ice Mystic Valley, the sword prodigy of the Sword-Seeking Sect... No, stop! My body can't take this!
