Wow, I heard that you're interested in system novels? Then I recommend the following five novels to you. They are all about firearms and systems ~ 1. "Doomsday: Start with a gun, build a tank in ten days": A male protagonist who wakes up in a global disaster. He has a god-level firearms system. He can obtain firearms by killing zombies. The title of the book stated that the male protagonist only used ten days to build a tank! 2. "Unlimited Arms System": The male protagonist Ling Feng obtained an unlimited arsenal in a fortuitous encounter. Facing the apocalyptic world where zombies were rampant, he drove armored vehicles and tanks to lead countless survivors to build a huge army and rebuild their homes in the ruins. 3. "Foreignland Weapon System": The male protagonist is a weapon craftsman who can produce firearms. He practices martial arts in his spare time. Using modern technology to create weapons, he used unprecedented firepower to launch a powerful counterattack against the demon creatures that were constantly surging towards him. 4. The male protagonist Tang Mo crossed into a completely different world and unexpectedly obtained the King of Arms system. He had unhesitatingly traded all his modern weapons to Li Yuan, the founder of the Tang Dynasty, to gain the approval of the emperor. From then on, he was in charge of preparing for the war against the Ruiluo Turks. 5. "Plane Plunder Expert": The male protagonist, Hao Yi, was an unscrupulous arms dealer who plundered all the resources he needed between planes. Born with the longsword, it was like a hot knife through butter. Under the test of each plane's circumstances and identity, it became more and more different.
