High Martial: After Becoming a Bad Girl, I Take Control of My Brothers

[Transformation + Gender Swap + Gender-Bender Romance + Invincible Protagonist + System + Power Fantasy] Xia Chuan You transmigrates to a high-martial world and awakens the Villain System, earning rewards whenever he does something bad. Wait, teasing Xiao Chu Nan counts too? Having decided that this guy is his best bro, Xia Chuan You figures that if things ever go wrong, he can just deny everything and fake his death. So he starts laying it on like a shameless flirt. “Bro, you're amazing!” “Bro, why's your face so red?” “What? Bro, you want to go hunting with me?” Wait, what do you mean, meet the parents? No way. I have to fake my death. This can't go on. Years later, Xia Chuan You lies trembling in a hospital bed, looking at his best bro and speaking in despair. “I can't be your best bro, your wife, your ⭐ toy, and your greatest enemy all at once! Bro, wake up.” “Why not?” Ye Chen says nothing, and simply begins to show off the ultimate skills he's spent his whole life perfecting. Later... Ye Chen: “Best bro, I'm sorry! Brother Chuan, Sister Chuan, Lord Chuan, please stop! I won't do it again!” Xia Chuan You: “Oh, what's wrong with our mighty lion?” This was all part of my plan. I would go from a wicked woman to the perfect wife, make you lose yourself in my tenderness, bear your child, and then, just when you fell in love with me, die right in front of you. Wouldn't you go berserk? Wait, how did you find me after I faked my death? What do you mean, you were reborn ages ago? Idiot, I didn't want you to find me! I wanted you to cry at my grave as the wicked woman I was, okay?
