The Son-In-Law Develops in a Low-Key Manner and Becomes Stronger by Relying on Connections.

When he entered Jiang's family, he was regarded as a useless son-in-law. He swept the yard, repaired fences, and planted vegetables, and no one took him seriously. In a world where martial arts is respected, weak families are oppressed, but he is willing to hide his edge and silently protect this family. No one knew that this man with "nothing to do" was once the master of the Shadow Pavilion who controlled the world. No one knows that he has awakened the "relationship value-added system" - when his relatives become stronger, he will automatically gain half of the increase in strength. Teaching her niece how to stand, she broke through and shook the stone pier with one punch; she helped the second young master do business, and his profits increased tenfold; even the old housekeeper had a sharp sword. He doesn't argue or show off, but if anyone dares to touch the Jiang family, raising a hand will be a disaster. He grew up in a low-key manner, pretending to be a pig and eating the tiger. In this life, he will protect his family and reach the top again!
