A novel with an exchange system

If there was an exchange system in the novel, it might be a system that allowed the characters to obtain various resources or items through certain means. The existence of this system could help the protagonist of the novel improve his living standards, improve his financial situation, and even become an important element that could change the entire plot of the novel. The Exchange System usually appeared in fantasy, science fiction, or martial arts novels. The characters could use this system to exchange for various items or resources such as weapons, equipment, herbs, experience points, and so on. By exchanging for system characters, one could obtain better equipment and skills to improve their combat ability, thus obtaining a higher status and more resources. However, due to the existence of the exchange system, the novel may involve some moral and ethical issues. For example, the characters can obtain more wealth and resources through the exchange system while ignoring their own moral bottom line or the reward for hard work. At the same time, the Exchange System could also cause some accidents and crises. For example, the character accidentally obtained something that he should not have or fell into trouble and danger because of the Exchange System. In short, the exchange system was one of the common elements in novels. It could help increase the complexity and variety of the plot, but at the same time, one had to pay attention to moral and ethical issues and possible negative effects.
