There were many plots about the main character's doppelganger in the novel " Devour the Starry Sky." Some of the novels, such as " The Crazy Doppelganger Evolution System,"" The Supreme Devour the Starry Sky,"" Devour the Starry Sky: I Have a Godzilla Doppelganger," etc. The main character had the ability to divide himself, and he could obtain new abilities and qualifications by devouring other creatures. Other than that, there were also some novels, such as " The Path of the Bloodline of the Devourer Star " and " Devourer Star: I am the Golden Horned Beast ", where the main character also had a clone, but the clone wasn't the main plot point. I recommend a related novel called " I Have an Infinite Clone System." The main character had a clone system that allowed him to create clones anytime and anywhere. I hope the above information is helpful to you.
