Zhao Belmonds and Jason Belmonds, two unlucky guys, were bound by the same cheating system in an accident, and traveled together to the dangerous world of Marvel and Los Santos. Because of the system scan, one of them turned into a blond and blue-eyed "little puppy", and the other became a "European and American strong man" with a face full of vicissitudes of life. Not only that, the system also threw a mean, talking Rottweiler "Xudong Cha" to them, euphemistically calling it the "lucky mascot." The "lottery system" that comes with Xudong Cha is even more exciting at every turn. It either draws out some weird props or teleports them to the duel scene between superheroes and villains. In order to survive, Zhao Belmonds, who was afraid of death, had to bite the bullet, and while complaining about "returns" and "complaints", he followed the reckless Jason and Xudong Cha, who only called "666", and began their journey to seek death in the Marvel world. While they are working hard to complete the bizarre tasks issued by the system, they also have to find ways to avoid the "care" of those superheroes and villains.
