After the Divorce, the Son-In-Law Turned Against the Will of Heaven

Traveling through an imaginary world, the whole family was killed, I became a son-in-law, the family property was occupied, the newlywed wife climbed into her lover's bed during the wedding night, they divorced, I stopped pretending, I am the richest man in the world... The enemy is attacking and the battle is short of food. I wave my hand and take the flowers! The household department was stolen and the national treasury was empty. I decided to make the country rich and the people strong.
