Western Fantasy: Traveling to a Different World and Returning to Earth

No one expected that Liang Le was the only one who finally decided to return to Earth. Before returning to Earth, Liang Le warned other travelers who had traveled from Earth. History is a continuous spiral. In the continuous rotating history of each country, no one knows how many people will die during this period. At first, Liang Le wanted to return to Earth, just for a better material life on Earth. He could smoke while watching the scenery, and play games when he got interested... Liang Le had sacrificed a lot to return to Earth, but as he continued to explore the world in depth, he slowly changed his initial thoughts... This different world is about to face a historical catastrophe, and it will force anyone who is willing or unwilling to be involved in it. No one will take the initiative to witness history, and witnesses have no choice. The giant army will launch a general attack on the human empire in the barren mountains; an unprecedented civil war will occur in the Elf Federation; various monsters in the underground world will crawl out from the cracks in the world again, and then bloodbath the entire world... Do ordinary people have any other choice besides running away?
