The Central Tower Threw Me into a World of Horror

The Central Tower is a mysterious place located in the center of the entire continent. It is not run by humans, but it has life. All justice mechanisms are formulated and judged by it. To put it bluntly... It's like the main system in the game. Lu Chengyin thought he was going to other worlds to fight monsters and earn supplies. Why does the world behind the cross-border door scare him so much that he wants to lie down and die on the spot... This novel and its characters are purely fictitious.
