A modern man from the 21st century got reincarnated in the crazy era of the 20th century. From famines to civil wars to the craziest thing ever seen in human history—the world war—this era, where the right and wrong are dictated by the strong, forces Jin to step on his moral bottom lines to survive. He had to do whatever it takes to get wealthier and stronger.
This is a story of a young man who will do the arms business and sell to whoever offers him the right price. In an era where the leaders of the top countries are all madmen, madness has become the theme of the era—a theme Jin hates but will still hop into and join to ensure his survival.
