Ultra: the Ultra Journey Begins with the Big Monster Fight

[The system ran away] + [Single female protagonist] + [Ultra fan] Lu Chen insisted on losing weight because he was too fat. When the weight on the scale finally became an integer, the universe deemed him "the law of conservation of mass has expired" and ejected him from the world as a bug. As a result, when I woke up, I found myself on the planet Polis. I also got the battle instrument published by the system, and also obtained King Gurant. Now that we are all in the Ultra Universe, let's have a good fight!
