Reborn, My Junior Sister Has a Bit of a Killing Streak

【A touch of universal adoration + all women and men are virgins + rebirth + revenge arc + dramatic love triangle + tycoon System + no BL】 In her previous life, Yun Xinci gave everything to treat her fellow disciples well. All she got in return was her master's indifference, her senior brother's distance, her second senior brother poisoning her, her third senior brother's disgust, and her junior sister coveting her heart's blood and golden core. Because of the System, she was reborn. In this life, she will avenge every wrong and settle every score. Her senior brother is too blind to see her worth and hurts her, but a few words are all it takes for him to shatter his own Dao heart. He was nothing special. Her second senior brother harms her time and time again. The only way to ease her hatred is to kill him. Her third senior brother wants to kill her, so she kills him too. Her junior sister drags her toward death. The only choice is to kill her with a single sword. Wait, her junior sister isn't dead, and has turned into a junior brother? No matter. She'll make sure to pull out the weeds by the roots. Her master may be highly skilled, but after taking her in, he never looked after her. When the others harmed her, he stood by and did nothing. Then she can ignore him for now, too. But... “Master, why are you crying?”
