Bai Ming transmigrated, but his body was gone, and his life was hanging by a thread. Fortunately, he had a cheat code: he could transform into a character from the Collapsed Iron Legion to cause trouble and prolong his life. No choice, to survive, he had to put on a show! So he became the Great Black Tower, making the Black Tower Space Station stand up and perform a spinning routine. He became Ruan Mei, conjuring a giant of light, triggering a universe-wide emergency response, and causing setbacks for the Legion and the Company at every turn. As a Firefly, he ignited the Star Sea and kicked the starship of the Abundant People to pieces. Then he became Huang Quan, annihilating the Abundant Envoy Shu Hu with a single strike. As a Robin, he copied songs from his past life online. Then he became Silver Wolf, frantically boosting his online traffic. Until the victim realized something was wrong… Great Black Tower: Interesting, someone is impersonating me? Don't let me catch you, you'll be in big trouble! Ruan Mei: What a clever idea, I really want to study this other me. Firefly: Are there other Grammer Knights in this world?! I must find her. Huang Quan: Is there really someone so similar to me…? Do you still remember those past events? ...As the number of victims increased, Bai Ming, who was contemplating how to go into hiding, suddenly looked at Aha, who had brought all the 'enemies' there, and fell silent. "What the hell, Aha!! You tricked me?!"
