Ten Years After I Got Married, I Became a Demon. When I Got Ashore, I Killed My Beloved Mother-In-Law First.

This is a fantasy world, where everyone is immersed in hard work and trying to reach the peak of life. After Ye Lan traveled through time, he discovered that his original body turned out to be a top-notch furnace body, and he was tricked into becoming the Feng family's son-in-law for ten years. For ten whole years, I was squeezed every day by Feng Ping'er, the scumbag of the Feng family, and my physique was almost drained. My daily life was worse than that of a pig or a dog. He thought he had exhausted his talents, but Yelan unexpectedly awakened the "Strongest Demon Lord System". He was surprised to find that he didn't need to practice every day. He only needed to punish and kill the evildoers to gain massive amounts of inner demons and become the strongest Demon Lord! Ten years after I got married, I cultivated demons. When I got ashore, I killed my beloved mother-in-law first!
