The God-like Son-in-law

To raise money for my mother's treatment, I became a live-in son-in-law. But my wife cheated on me, and the old matriarch publicly humiliated me. After witnessing my mother leap from a high platform at the hospital, I was filled with hatred. I hate the injustice of this world! I hate their entire family! A white light descended, and I saw countless mortal emperors bowing to me as their sovereign.
