😋I recommend the following novels to you, hoping to meet your needs: 1. To Marvel as a Mercenary: The story of Harry becoming a mercenary who is both good and evil. It suits your needs. 2. " Military Concubine: Dominating Enchantress ": Although it is an ancient romance novel, the protagonist is the strongest mercenary killer. It fits your needs very well. 3. " King of Special Forces ": The protagonist is a special forces soldier who creates his own mercenary team. It suits your needs very well. 4. [I'm a Mercenary in the United States: The main character is a mercenary who travels between Marvel and PC. It also meets your needs.] The above is my personal recommendation. I hope you will like my recommendation.
