I'm in the Demonic Sect, but my cultivation techniques are being used for palace intrigue

Deep within a demonic sect, one disciple's cultivation has grown perilously crowded: every technique he practices has awakened as a scheming, sentient persona, and now his arts quarrel like rival consorts locked in imperial palace intrigue. From the depths of the void, the Imperial Ruins Scripture bellows its arrogant ambition to rule every cultivation method under heaven, demanding to know who agrees—and who dares oppose. The Heavenly Demon Joyful Union Scripture answers with an alluring voice steeped in bone-deep resentment, coldly vowing that today's humiliation will be repaid a hundredfold. The Universal Annihilation Scripture spirals in destructive madness, shrieking that if it falls, it will drag every rival down with it, sparing no survivor. Meanwhile, the Heart-Eating Soul-Controlling Technique sweeps seductive eyes across her competitors and coos that her service in helping her master control a Nascent Soul old monster has surely earned her a seat upon the throne. Surrounded by these jealous, ambitious arts—each craving supremacy, favor, or outright ruin—their beleaguered master can only issue a decree of his own: as long as he draws breath, every one of them shall remain his concubines. Surviving the demonic sect's cutthroat world is hard enough; keeping a harem of warring cultivation techniques in line may prove the true impossible art.
