It's an Apocalyptic Game, but My Account Is the Second Game

"Did you know? In 2088, the Earth where I live became the most popular planet for alien civilizations in the Milky Way. That year, all races came to Korea, and hundreds of millions of aliens came here every day to participate in the grand event." "Really? Are you so powerful after a few decades?! How did you do it?" "Of course it is true, because then humanity on earth will perish." "..." But it doesn't matter, at the end of the world, I will hold up the wheel of time, declare the end of this world, look back on the past, and rewrite a new ending. This is a new work by a newcomer, but I have some regrets about the writing. It's a slow read. The first thirty chapters are mostly about daily trivialities and world view. After the thirty chapters, the plot starts to accelerate. Please bear with me (make a fist)
