After Becoming Invincible, I Came Down from the Mountain and Became a Door-To-Door Son-In-Law.

The invincible immortal came back alive, but chose to remain anonymous and became the son-in-law of the Lin family in Jiangcheng. Everyone thought he was a freeloader, and even his nominal wife treated him coldly. Little did they know, he could destroy an aristocratic family with a snap of his fingers and subjugate an area with a wave of his hand. When all the forces were about to move, and when the beautiful women fell in love one after another, the seemingly salty son-in-law finally slowly opened his eyes... In this life, he just wanted to protect the one he loved and, by the way, have some soft food.
