In a parallel world, Chen Ge, a mercenary, joins the Wagner Syrian project on January 24, 2022. The good news is that he has obtained enhanced strength, allowing him to wield a rocket-propelled grenade launcher with one hand, loading the grenade with the other, and firing with precision. He earns the nickname Cannon King. The bad news is that the Russo-Ukrainian conflict is about to erupt, and this Cannon King will undoubtedly be redeployed to Europe to fight. He trades his ISIS-hunting skills for a new battlefield, becoming the main character of the novel.
