Madam, Don't Be Afraid, I'm a Good Person

There is no astonishing business talent, no resourcefulness to predict an enemy thousands of miles away, and no force to match a hundred. All he has is the insight of a 21st century soul, a glib mouth, and a body that can fight. He is the most remote branch of the Marx family, the leader of the gangsters who collect protection money in the streets, and a ruffian who is strong on the outside but soft on the inside in the eyes of the widow next door, Serena. He used his street smarts to drive away the strong men seeking revenge, used his sharp tongue to win over people's hearts, and used modern knowledge to survive in this empire that valued literature over military affairs and had solidified classes. A secret book on breathing techniques with shady origins opened the door to his extraordinary power. However, this seemingly prosperous empire has been crumbling due to internal and external troubles, and it fell apart in just a matter of days. He doesn't want to be a hero, he just wants to eat meat and drink wine, chase the widow he likes, and survive in this troubled world. But fate never allows little people to settle for mediocrity and forcefully carve out a bloody path when the empire is about to collapse.
