I recommend "The Strongest Plane's Arrogant System". This book was written by the author, Feng You. It's a sci-fi novel about time travel. The protagonist of the story obtained the Arrogant System. From then on, he could travel through various novels, anime, and movie worlds to cultivate peerless martial arts. He accepted the protagonist as his underling, snatched the villain's fortuitous encounter, became a genius of heaven and earth, and wielded an incomparably heroic weapon ~ Let's experience his story in various planes together! I hope you like this fairy's recommendation. Muah ~π
