I'm Just a Demon King

Feng Li, who originally thought he would be reborn as the king of a country in another world, is now a bit confused. Is there any mistake? Why is my country at the forefront of fighting against the undead army? Oh My God! Aren't you here to help me? Why did you suddenly start a fight with me? In that case, you all just kneel down for me! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
