You Made a Weapon for Military Training, So What Is This Laser Cannon?

(Urban) (Cutting-Edge Technology) (System) (Some Warhammer elements) (Interstellar) (Superpowers) In a parallel world, during military training at a science and engineering university, the instructor orders everyone to make their own weapons for the exercises. The next day, Li Chen shoulders a model laser cannon he stole from his uncle and heads to the sports field. When he tries pulling the trigger at a tank that has stalled, everyone who watches the main battle tank turn into fireworks is... stunned. Instructor: “Captain, our anti-tank guns don't seem so impressive anymore.” Principal: “Sir, let me explain. This really is just military training. We aren't conducting dangerous experiments.” Professor: “Has the pulse cannon I just developed already become obsolete?” When the military comes looking for them, Yu Ling realizes he can no longer keep his secret. Materials restrictions have also become a bottleneck, and the System's genetic unlocking progress has stalled, so he decides to join the national team. Then portable nuclear power units, Thunder armor, space stations, near-light-speed craft, and more begin to appear one after another... Just as other countries accuse Longguo of abandoning them to evolve alone, hyperspace engines are installed on starships. The moment the barriers of physics in the real world are torn open, psychics begin awakening all over the world! Meanwhile, mysterious beings in hyperspace also open their eyes and watch humanity!
