After Being Exterminated by the Empress, I Awakened the Killing Godhead

I was once the youngest Duke Wen of Dayan, and I assisted my beloved wife to ascend to the supreme position of the Nine Five-Year Plan. I thought I could create a prosperous future with her, but in exchange, I had my whole family raped, drank poisoned wine by her own hands, was imprisoned in a dark prison, and died of torture. Before she died, she chuckled in my ear: "Husband, your kindness is worthless." When I opened my eyes again, I returned to the eve of the destruction of my country and my family! Kindness? It has long been buried by my own hands! In this life, there is only endless killing intent and madness in my heart! Bite! The host's overwhelming hatred is detected, and the 'Killing Tyrant' system awakens! [Killing one person can increase Qi and blood, and the body can become holy! [Kill a city to get points and summon the eternal demon army! Empress, don't you think my kindness is ridiculous? Then I will transform into a tyrant and use your country and the bones of hundreds of millions of people to build you a tombstone of eternal repentance! When I lead a million demonic troops to break through your imperial city, I will let you understand what real fear is!
