Why are My Disciples Acting So Strangely?

[Yandere + Love Triangle + Multiple Heroines + No System] Transmigrating to the world of cultivation, Gu Chen is a genius who appears only once in ten thousand years, and he condenses his Nascent Soul in a hundred years. But he grew tired of it and decided to abandon the tedious cultivation and travel the world, where he rescued several little girls along the way. The girls he picked up were all pitiful: orphaned girls who had been sold out, princesses of the Feather Clan whose wings had been broken, girls being hunted down... He taught them everything he knew, just so they could protect themselves, and then quietly left one morning, concealing his merit and fame. Gu Chen always felt he was incredibly lucky, encountering trouble wherever he went, as if orchestrated by an invisible hand. So he began to lay low and stop meddling in other people's business. Two hundred years passed, and he leisurely cultivated to the peak of the Nascent Soul stage, feeling he could continue to live a carefree life. Until this day, the sky above the sect was filled with radiant light and celestial music. The female demon leader of the Demonic Sect stood on a black lotus, her face beaming with smiles: "Master, I've found you." The Nine-Tailed Fox King of Qingqiu blotted out the sky, its eyes dangerous: "You think you can just leave me behind?" His first and eldest disciple, wielding a long sword, had a stubborn and dark gaze: "Master, please explain... what's going on with all these 'junior sisters' of mine?" Looking at the group of "good disciples" in front of him, whose lowest level was at the Refinement stage, and then feeling his own pitiful Nascent Soul Perfection cultivation, Gu Chen fell into deep thought: Why are they all yanderes!
