After Being Abused by My Sister-In-Law-To-Be, My Stepbrother Avenged Me

My stepbrother is a paranoid lunatic. He was the youngest chief minister in the dynasty, with a heart of stone, and was feared by countless people. Just because I said one more word to my stepbrother, my stepbrother went crazy and slaughtered the whole family. Anyone who commented on his pathological possessiveness towards me would be tortured to death by him. He said that he is my only relative in this world, and I can only look at him for the rest of my life. I didn't want to live under his control, so my stepbrother sent me to a nunnery and asked me to learn the rules. In three years, I became extremely obedient, and he was the only one in my eyes. On the day I was able to go home, the carriage was stopped by the eldest princess who was engaged to him. Her face was arrogant and disdainful and looked very similar to mine. "I'm going to teach you, this fake nun, what shame is today!" She shaved off my head, cut off my tongue, disfigured my appearance, and finally crushed my legs to make a beauty bowl. On their wedding day, it was given to their stepbrother. "The pheasant outside wants to seduce my husband because he looks similar to me. This princess has already dealt with it. This beauty must be used by my husband every day, so as to slay the chicken to scare the monkeys!"
