I'm on Earth, I'm a Three-Faced Wall Person

When the sun is about to flash, the earth begins a long wandering journey in the universe, and human beings can only live in underground cities. "Are you a Trisolaran civilization? Do you want me, an Earthling, to become your wall-facer and work together to deal with the powerful Earth civilization? " Chen Yu was a little puzzled, pointing to the water droplets floating in the universe, "The technology of using strong interaction to tightly arrange hydrogen atoms can't deal with earth civilization?" The Trisolaran representative shook his head, indicating that it was not enough. Then Chen Yu pointed to the invisible Sophon next to him, "You can touch the eleventh dimension and master the technology of nine space dimensions, but you can't deal with the earth's civilization?" The Trisolaran representative still shook his head, indicating that it was far from enough, and explained, "Your Excellency, Wall Facer, do you know about Small Universe? A small universe that can hide the mass of hundreds of solar systems may actually exist only the size of your button. " Chen Yu: It's a mouthful. This book is also called "I, the most powerful person in the Three-Body Civilization, am an Earthling" This novel and its characters are purely fictitious.
