Game Dungeons Descend, and I Fight Monsters to Unlock High Tech

[Game dungeons] + [Global Awakening] + [System cheat] + [Leveling up and growing stronger] + [No harem] Game dungeons descend upon reality, and everyone awakens to a game class. Some classes are strong, others weak, and Chen Mu awakens to the universally derided worst class: Gunner. Everyone tells Chen Mu to settle for easy runs in low-level dungeons and not attempt anything too difficult. “Times have changed. Who even uses guns anymore?” “Exactly! Gunner is a trash class!” Chen Mu ignores them. “Gunner is the worst class? That’s because you don’t understand it!” “Gunner class advancement: Mechanist!” “Xiaowei, unlock high technology for me!” “Ding! High technology unlocked: Radiant Moon Battle Armor, Type III!” “Ding! High technology unlocked: Spirit Marsh Battle Angel, Type I!” “Lastly, Xiaowei, unlock that one for me!” “Ding! High technology unlocked: Scorching Sun Mech, Type I!” With a mysterious high-tech System, Chen Mu single-handedly defeats the seven most powerful legendary bosses in the game dungeons, proving the worth of both the Gunner and Mechanist classes!
