The Supporting Female Lead Waters a Divine Tree and Catches Fish from the Female Lead's Pond

Lazy Lin Shuyue discovers that she has transmigrated into a cultivation novel. What wonderful news! She can be a lazy fish in the cultivation world. The tragic part is that she isn't the heroine, but a supporting female character who serves as a stepping stone for the heroine's ascension. The person she loves, her moonlight, teams up with the heroine to destroy her family. The heroine, Heaven's chosen darling, gets the Lin family's alchemical inheritance. Because of her constitution, the male lead offers her to an elder of the Hehuan Sect to serve as a cultivation furnace. Hate born of love drives her to cultivate demonic arts and absorb yang energy. Her power skyrockets, but even when she surpasses the male and female leads later on, she can't escape the heroine's heaven-blessed luck and is slain by the pair. Her genius elder brother is away cultivating and survives the calamity. Following the clues left behind, he tracks down the culprits and avenges his family, only to be killed by the heroine's fish. Shuyue, newly arrived from another world, looks at the script in her hands. How can this family be any more tragic? Can we just not play this hand? But the little tree in her sea of consciousness says no. I need water! Little Tree: Give me water, and this divine tree can help you become an immortal. Lazy Yue: I know that pie-in-the-sky pitch. Whatever you need me to do can't be simple. I refuse. I don't want to work. Little Tree: Then keep being a demonic supporting character, with the male and female leads' blades at your throat. Lazy Yue: Wait, maybe there's still hope for me. A witty, bickering, beautiful little fairy and a quiet, cool-headed, capable straight man
