The Super Lady Wrangles the General

"Jiang Shuyu, a violent lolita and internationally renowned boxing champion, transmigrates into the body of a tragic, love-obsessed female supporting character with the same name as herself after criticizing a Mary Sue novel. In the original story, Jiang Shuyu, a princess, is demoted to a concubine on her wedding day. Zhan Suining and Jiang Wanwan even use her wealth and the remains of the loyal and patriotic general Zhan Yanting to rise to power. She transmigrates to the very day she marries the male supporting character. Faced with this disastrous start, she resolutely crushes the jade ruyi she's holding and declares war: 'Scumbag Hanzi Cha, your retribution has come! From today onwards, this book is my story, Jiang Shuyu's story! Zhan Yanting! Don't be afraid, your wife is here to save you!'""
