I recommend the novel "Interstellar Duplication" to you. The main character has the Star Spirit Duplication System, which allows him to replicate the universe's strong warriors and the heroes of various races. He also replicated the armored warriors, Ultraman, Captain America, Godzilla, and others in the special film to help the main character destroy the enemy. In addition, the main character could also copy the main characters and supporting characters in the Xianxia drama to help the main character establish a glorious sect. The reason I recommend this novel is that there is a copy ability in it, and it is quite powerful, just as you mentioned in the description. I hope you like this fairy's recommendation. Muah ~😗
