Do You Regret Destroying My Entire Clan and Turning Me into a God of Murder?

The protector of the country died in the rebellion. The conspirators are extremely glorious. My sister was bought and sold at will, my aunt was persecuted, and my relatives were reduced to livestock in captivity... Then I have a punch with terrifying killing intent, and I have a sword that can crush everything! The God of Death descends from the mountain. Then let everyone in the world prostrate themselves and tremble!
