, I recommend the following novels to you. They are all sci-fi novels where the main character has the ability to exchange or infinite elements: 1. 'The Great Adventure of the Heavenly Warriors' was a cool novel where the protagonist dominated the universe in the myriad worlds. 2. In "I Have a Super Exchange System", the protagonist had a system subsidy in the apocalypse. He could build and exchange for everything he needed. It was not an abuse of the protagonist. 3. In "Tom the Cat Breaking Through the Dimensional Wall," the main character was on missions in various worlds all year round. He could splash the glory of the cat race, not abusing the main character and had unlimited elements. 4. In the Heavens Redemption Lottery System, the main character was adventuring in different worlds and could exchange for all kinds of things. 5. "My Doomsday Base Is A Little Invincible". The main character had the base system's subsidy and survived in the doomsday. It was not a cruel story. I hope you like this fairy's recommendation. Muah ~😗
