Reborn with the Spendthrift System, My Senior Sister Makes a Comeback

Chen Mengchen devoted herself to helping her senior brother, only to be betrayed by the ungrateful man. He shoved her in front of a demon beast to shield his beloved, and she never expected that in the next moment she would be reborn just after being injured in the first round of the sect tournament. She also bound herself to a Spendthrift System. In this life, she swears she won't be a lovesick fool: she'll seize opportunities, crush scumbags, and take over as sect leader herself.
