Reborn, but I Didn't Get Rid of My Nemesis

Everyone in the cultivation world knows that Yuluo Sword Venerable, the greatest swordswoman, and Qianmian Lord, the head of the Unorthodox Path, can't stand each other. Back then, Qianmian infiltrated her sect to steal a treasure, ran Yuluo through, then pinched her chin and smirked arrogantly. "Thanks." Later, Yuluo broke into the Unorthodox Spirit Realm, plundered the spirit herbs Qianmian had spent years cultivating, snapped both his hands, then stood on his shoulders with a cold, mocking smile. "You're welcome." From the moment they began cultivating, they spent thousands of years sabotaging each other. A little fight every ten years, a major one every hundred. The mushroom clouds rising in the sunset were the youth of generation after generation of disciples. Everyone in the cultivation world believed these two prodigies would surely fight to the death, and that even if they ascended, only one of them would make it. They were right. The Heavenly Dao collapsed, ten thousand demons appeared, and the human world became a hell. Everyone had no choice but to join forces, including sworn enemies. The final battle required someone to give their life sealing the Abyss. Neither of them wanted to die, so they fought one last time with everything they had. At the moment between life and death, Yuluo suddenly decided that being the greatest cultivator in the world and cleaning up the Heavenly Dao's mess was no fun at all. So she jumped into the Abyss of her own accord, leaving Qianmian Lord to deal with the disaster-ridden mess. After being reborn, Yuluo decided that Qianmian could take care of the world, so she settled in to lie flat. In this life, she couldn't be bothered to provoke Qianmian. But the sickly junior uncle in her sect, who was such a shut-in that his disciples often wondered if he'd stopped breathing, became more and more active. A little too active, in fact! Little junior niece, my heart hurts. I'll have to leave my lessons to you. Little junior niece, I'm dizzy today. I want some East Sea Jade Dew. Little junior niece, I'm at death's door. My last wish in this life is to have a bite of fairy mushroom pastry... Yuluo calmly added a tiny bit of salt to his jade dew. "You look perfectly healthy to me. You could easily outlive that old tortoise at the sect gate, Qianmian Lord."
