Gun-World's Defense Master

In most worlds， heroes swing swords and cast spells. They charge in and win by being stronger. This is not most worlds. Here， guns have souls. Every bullet costs money. Every shot can be your last. And the people who survive aren't the strongest—they're the ones who know how to count. Sandek died during a game competition. He lost to a pay-to-win player， even after pulling off every trick he knew. Then he woke up—in a world that runs on the same rules he spent his whole life mastering. A world of guns， souls， and ammunition. A world where shooters can cross through portals into other dimensions and bring back technology that doesn't belong here. A world where attachments can enhance any weapon， and where special bullets—ice， fire， water， lightning—can turn a losing fight into a winning one. 　　Sandek knows this world. Every rule. Every trick. Every bullet. He's not the strongest. He's not the fastest. But he's the one who knows how to make every shot count—and how to make every cheap trick work. He doesn't fight fair. He fights smart. What to expect: · A gun-based world where calculation matters more than power · A weak-to-strong protagonist who wins by outthinking enemies， not outgunning them · Special bullets， soul-bound guns， and weird potions that can shrink your head or make it huge · Portals to other dimensions， where shooters scavenge technology and bring it back · Weapon attachments that can enhance any gun—if you can find them · A LitRPG system focused on skills， inventory， and tactics—not endless stat sheets · A world where guns have souls， and every bullet has a price · No swords. No magic. Just guns， rules， and a player who knows how to break them. If you enjoy this story， please leave a comment or a review. If it stays quiet， I'll take it somewhere else.
