What Should I Do After Becoming the Heroine's Tonic?

Lin Lin transmigrates into a book and finds herself in the body of a minor character who shares her name in a cultivation Mary Sue novel. In the book, Lin Lin is the heroine's younger sister. Unfortunately, she is arrogant and unruly, and uses her natural talent and abundant spiritual power to do whatever she pleases. She frames the heroine and seduces the male lead. In the end, the male leads join forces to imprison her in an underground pool, destroy her spirit weapon, and turn her into a human pill furnace, using her flesh and blood to nourish the heroine's spiritual power. With Lin Lin sustaining her, the heroine's spiritual power surges. She soon breaks through her bottleneck and ascends with the male leads. As for Lin Lin, the heroine drains her of spiritual energy, and she dies bleeding from all seven orifices. The newly arrived Lin Lin is undaunted. Having read countless novels, she firmly believes that if she can resolve her differences with the heroine, she will be safe and sound! Once the heroine attains the Dao, Lin Lin will rise to glory in her wake! She might even win the heart of a supporting male character! But the pain of her pierced collarbones tells her she's been submerged in a water prison. Oh, it seems they've already destroyed her spirit weapon and refined her into a dinglu... * As an exemplary Marxist who grew up under the core socialist values, Lin Lin takes a deep breath. Abandon illusions, prepare to fight! She'll fight to stay alive! Even a dinglu can cultivate! Years later, Lin Lin has become the revered Mother of Heaven and Earth, worshipped by cultivators across the land. But she's so busy she never gets a moment to slack off. Lin Lin: I regret this. I really, really regret it. * P.S. There is a male lead. One-on-one, with both leads devoted only to each other. He's a guiding light on the heroine's path to growth. Incredibly powerful, but a little tragic. Theme: Your life is in your own hands.
