I Am Invincible in the World

On the day I got married, before my husband entered the new house, he took his cousin Xu as his concubine. In order to fulfill the love between my niece and my son, my mother-in-law gave me a chronic poison. Mrs. Xu fell into the pond and accused me of pushing her into the water. My husband slapped me and threatened to divorce me. I pulled out the soft sword hidden in my waist, cut off one of my husband's arms, and pushed Xu's head into the pond seven times. My mother-in-law called me a bitch and asked my nanny to take me into the ancestral hall. I stepped on my mother-in-law's face and spun her around three times. My father-in-law came to arrest me with his family guards. I broke the guard's legs and I even stabbed my father-in-law's eyes out. Before this, no one knew that I, a rich man from an official family, had been taught by a demon in the world when I was young. This demon wanted to help me break through the realm, but I practiced secretly, and on that day, I killed the demon master. Now, I'm exposed! I don't want to work as a noble lady anymore, I want to change my life. For example, riding a horse in the rivers and lakes, and then doing some chivalrous and righteous things~ Small notice: Updates will be made intermittently starting from January and will be completed before March~~ Reading guide: 1.
