In terms of story concept, a real sharpshooter encounters Waterloo in the virtual world. The name of the protagonist Wang Jie is very down-to-earth and fits the simplicity of retired soldiers. I think of several possible development directions: Focus on the growth line: starting from the frustration in the Internet cafe, the protagonist uses military thinking to re-understand the game mechanics, such as converting gun pressing skills into mouse control, and integrating tactical positioning into game consciousness. Finally, he shocked the e-sports circle with his realistic battlefield tactics in the international arena. The protagonist discovered a loophole in the game engine and combined his knowledge of firearms to magically modify the equipment, such as using a military-standard sensor to replace an ordinary mouse. As a result, he was questioned by the event organizing committee as a cheat. What needs to be proven is your own strength rather than equipment superiority. There are battle scenes in the game that are highly similar to the protagonist's real experience. The game company is suspected of stealing military secrets, and the e-sports competition becomes a cover to find out the truth.
