The Perfect Son-in-Law

At ten, I awakened to the truth: I was the reincarnation of the Demon Lord. I had to practice ten years of silent meditation to strengthen my immortal body before setting foot on the path of cultivation again. Who could have guessed that I would endure ten years of humiliation, even having to marry into another family as their son-in-law just to survive? The ten-year period ended on my wedding day, and the Demon Emperor returned. How could I let mere mortals insult me? In this life, everyone who hurts me will pay the price. Everyone who bullies me will be crushed beneath my feet. I am Zhang Pengfei, the Demon Emperor. Across the nine heavens and ten realms, I alone reign supreme!
