Science Fiction Invades Another World

Tang Yuan traveled through the fantasy world of high martial arts and became a small lord, but got a technological artifact! Since then, we have developed a scientific and technological army, created the Internet, built online shopping malls, developed virtual reality games, and built portals... To create an alien version of a modern science fiction city and unify the world at the same time. (PS: This article focuses on changing the world, and is supplemented by unifying the world!)
