As a Demon King, I Want to Fight Ten Billion Heroes?

Ten billion people around the world have been forcibly transported to a new world. Everyone is a brave man! Defeat the devil and rescue the princess! It is our duty to rebuild the glory of mankind! This is the brave man! But what does all this have to do with Luo Hong? He is the devil! Ten billion people traveled through time, ten billion brave men! He is the only one who is the devil! In other words, if the heroes decided to unite to defeat the Demon King, he would have to fight 10 billion heroes by himself! But brave men don't care, they only think about their own interests! But when Yong rushed to the castle to save the princess, he saw Ghidorah and Grizza standing there quietly. There was also an army of extremely transformed mega fire-breathing dragons next to him. Perhaps? The brave man doesn't have to save the princess? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
