Thousand Years of Reincarnation: I Am Not a Brave Man, but I Will End the Troubled Times

Every 1,000 years or so, the Demon King will be almost unable to suppress the desire to destroy the world in his body, and will become the plaything of the gods. A Demon King who is not mentally strong enough will not even survive 10 years. Every time the Demon King attacks, it will cause great destruction to mankind, because conventional means cannot hurt the Demon King. … More than 1,000 years have passed since the last war. Now, the Demon King has come again, and Zen, as the leader of all mankind, will lead mankind to win this victory. "Even if you are a god, I will kill you to show you. After all, I am the protagonist!" [Protagonist is not in time travel] [No system] [Protagonist is not invincible] [Harem] The author said: I adopted a little bit of the world view from other games and anime, and everything else is my own creation.
