Please recommend some novels with an exchange system!

😋I recommend the following novels to you: 1. [Zhu Xian Exchange System: The transmigrated youth gradually grows into the strongest person in the entire Heavenly Fate Continent with the help of the system.] 2. "System in Hand": Lin Hao returned to his seventeen-year-old youth and accidentally activated the rebirth exchange system that accompanied his rebirth. He could exchange knowledge, skills, bloodlines, props, and so on, thus embarking on a unique path. 3. [Exquisite Exchange System: The otaku Bai Shifei transmigrated into a useless young master of an abandoned race in a barren city. He accidentally activated the exchange system hidden in the ring and embarked on the path of a strong man full of adventure and passion.] 4. "Invincible Exchange System": The main character can buy pills and out-of-print divine artifacts that others can't get even if they go through mountains of knives and seas of fire in the Invincible Exchange System, as long as they have money. 5. [The Strongest Exchange System in History: The protagonist has the strongest exchange system in history. He can travel through all kinds of planes and worlds and embark on the path of a monster.] I hope you like this fairy's recommendation. Muah ~😗
