The First Son-in-law

*Two months ago, he became the son-in-law.
Every day he needs to clean up the house and cook for his wife, People call him his son-in-law, but more accurately, he was more like a servant and a babysitter.
But no body knows he is the King of the Underworld, called the God of Death!
“How could you be working as a lawn mower in this family?”
"What do you know? This is love!I had looked for this peaceful life for a long time." he answered happily.
But his enemies wouldn't agree，A great crisis is near...
Could he protect his lovely wife？As the King of the Underworld what would he sacrifice to keep it all ？
