The Demon King's Journey to Another World

Traveling through time with the highest-level Demon King character template in the game, I started in a dilapidated territory, with all low-level soldiers under my command, surrounded by enemies, and there was another army of Demon Kings from another dimension sharpening their swords, intent on invading? Eric said that this is nothing. There is no enemy that cannot be eliminated with one fireball. If there is one, then two! In short, this is the story of a demon king who is determined to be the savior, who spends his free time teasing and flirting with his female subordinates, while also leading the people of another world to become well-off~~ The author is a Buddhist, please give me flowers and tickets~~ This novel and its characters are purely fictitious.
