After My Beloved Junior Sister Pierced My Heart with Her Sword

I fell into the demonic realm and became an invincible Demon Lord. The junior sister from the Celestial Realm, whom I had once cherished above all else, gave herself to me and said she would marry me. But on our wedding day, she led the celestial soldiers there to surround me. A Demon-Slaying Sword pierced my heart. Standing behind me, my junior sister twisted the hilt of the sword in her hand and said through gritted teeth, “You were the one who killed my A Zhuo!” They ripped out my immortal bones, whipped my corpse, and displayed it for all to see. I died a horrific death. Reborn, I would turn the Six Realms upside down.
