A House of Loyal Heroes, and I Am the Great Qian Dynasty's Number One Villain

I was born into a family of military heroes, and I’m blind. My whole family was fiercely loyal and righteous, and they died in battle, leaving us fallen into ruin. On the day of their funeral, my fiancée came to break off our engagement, while six beautiful women who were supposed to become my sisters-in-law insisted on marrying me instead, drawing ridicule from the whole city. But they don’t know that during these three years of blindness, I’ve quietly become invincible under heaven. When a tune can break the heart, who in all the world could stand against me?
