Switch to Gunsmith Profession and Start Hunting as a Black Market Hunter

In this era of national awakening, Lu An awakens to become one of the weakest professions [Gunsmith]. Because I couldn't afford the tuition and couldn't afford to practice, I chose to drop out of school. Later, he chose to be an apprentice in a repair shop. Just when he was feeling sorry for his mediocrity in this life, he found a darkness in his mind. A nebula appears in the darkness. As long as it absorbs the pure spiritual energy in the spiritual crystal, the nebula will undergo qualitative changes and emit extremely dazzling light. When the nebula is filled, you will get a half-life weapon! In order to earn training resources, he chose to join the black market hunter. As his realm increased, Lu An discovered how incredible this ability was! Light up the first-order nebula and obtain [particle-charged dual guns] Light up the second-order nebula and get the [Netherworld Sniper Rifle] Light up the third-order nebula... Until one day when a nebula was filled up, Lu An discovered that the truth was not what he thought. It turns out... That firearms also have contrasts? "No, how did your small pistol emit a beam of light tens of meters high!" "How come your sniper rifle fires a nuclear bomb!" "Why are you armed? What is that armor? Why are they all weapons? Are you going to destroy the world?!" Lu An just wanted to laugh. "I'm just an ordinary gunsmith!"
