Awakened the Sign-In System, I Became a Cultivation Maniac

【No CP + Leveling Up + System】 After transmigrating into a male-oriented novel as the wicked female side character who breaks off her engagement, Lu Xueheng has this to say: Since the arrogant male lead already hates me, I might as well get even stronger. After obtaining a sign-in System, Lu Xueheng signs in once every day. Today, she gets the male lead's cultivation manual. Tomorrow, she gets his magic weapon. The day after, she gets his legacy. Lu Xueheng keeps fighting monsters and leveling up, only hoping to stay alive. Before she knows it, she has become the foremost sword cultivator. The male lead, planning to reclaim his lost pride, looks at Lu Xueheng's stats, which are almost identical to his own, and her experience bar, which is far higher than his. Male lead: Weren't you supposed to be invincible? Lu Xueheng, who only wanted to stay alive, grins. Sorry, I'm ascending now.
