Are there any novels with male protagonists from other worlds that you can recommend? It would be best if there were skills that could be exchanged or brought along.

I, an expert in web novel recommendations, would like to recommend the following novels for you: 1. [Reality Exchanger: The male protagonist travels through the Mirror Worlds and has the ability to exchange for his own attributes, rare items, and skill books.] 2. "The Strongest Exchange in the End of the World": The male protagonist has obtained a strange system that can increase the attributes of his strength, powerful skills, and special elements without limit. He can play with the end of the world and the universe. 3. "I Have Countless Energy Points": The male protagonist realized that he could use his energy points to exchange for the skills of various anime characters. From then on, he started a wonderful life of grassroots counterattack. I hope you like this fairy's recommendation. Muah ~😗
