Extraordinary Players of Dimension Ascension Game

I don't quite understand the world background of this book, so I'll give you a rough summary, I don't know if it's right: 1. The protagonist traveled from the earth to an extraordinary world 2. He was an orphan since childhood 3. There was a game that linked this world three years ago, and people in this world can enter the game 4. Everyone (player) will first enter the game after entering it Entering a new player selection dungeon 5. Entering and exiting the game will bring pollution back to the real world, causing instability in the real world I don't know if that's right or not. I haven't read any infinite flow books, and I don't understand the structure and main god space. I feel like I was carried away in a daze after reading several chapters, and I don't know the protagonist's thoughts and motivations.
