I Am the King in the Apocalypse of Another World

The end of the world is approaching, and the universe is in danger; the invasion of evil tribes is imminent, and there is a glimmer of hope in despair. Mysterious life experience, strange opportunities, what does it matter as long as I can become stronger? Although I don't belong to this world, there are people in this world that I want to protect! I am the king of this world, and I protect this world. "Based on everyone's suggestions, in order to facilitate everyone's experience, I have re-planned the plot and made changes to the previous plot. I hope everyone will like the revised plot."
