Lan Qinghe transmigrated into a cultivation novel as the villainess and was "bound" to a useless system named Bai Ling. Tasked with protecting the genius female lead Ji Linxue, she assumed the mission would be easy – until she kept getting saved by the very person she was supposed to protect.

After yet another rescue, she ranted inwardly, "Who's protecting whom?!" The next second, Ji Linxue was struck by a rock and collapsed in her arms. By day, Lan Qinghe cultivated diligently; by night, she transformed into a little tiger, using Ji Linxue's glacial spiritual power to ease her heat cycle.

One evening, as the female lead stroked her tiger ears, she asked softly, "Jiejie, does it feel good?" Lan Qinghe was stunned – how did she know? The system feigned ignorance. Then Ji Linxue wrapped her arms around Lan Qinghe's waist and whispered, "Because I like jiejie the most – so I want to know everything about her."
