After Becoming a Cannon Fodder, I Stole the Heroine’s Fortunes

Liu Qiyue died suddenly and transmigrated into a novel about cultivating immortality that she'd just finished reading before her death. There, she became a cannon-fodder supporting character with the same name. To stay alive, she decides to seize the heroine's opportunities and become a powerful cultivator before the heroine can come into her own. She devotes herself to secluded cultivation, intent on following a romance-free, no-CP path of emotional detachment and female strength. She never expected some roguishly handsome young master to come out of nowhere and cling to her. There is a male lead, but he doesn't get much page time. The romance comes much later, in the second half.
