Military Training Homemade Weapons, What the Hell Is This Laser Cannon?

(City) (Black Technology) (System) (Part of Warhammer Settings) (Interstellar) (Superpower) In the parallel world, during the military training at the Polytechnic University, the instructor required homemade weapons to participate in the training. The next day, Li Chen came to the playground carrying the laser cannon model he stole from his uncle. When he tried to pull the trigger on the parked tank, everyone who watched the scene where the main battle tank turned into a firework... Went numb. Instructor: "Captain, the anti-tank gun in our hands is no longer good." Principal: "Chief, please listen to my explanation. We are really doing military training and we are not conducting dangerous experiments." Professor: "The pulse cannon I just developed has become outdated equipment?" When the military found his home, Yu Ling knew he couldn't hide anymore. Due to the bottleneck in material control, the system's gene unlocking progress had stalled, so he decided to join the national team. Then, portable nuclear power devices, thunder armors, space stations, and sublight speed vehicles appeared one by one... Just when various countries accused the Dragon Kingdom of abandoning them to evolve alone, the subspace engine was installed on the starship. At the moment when the physical barriers to reality were torn apart, psykers began to awaken around the world! At the same time, the mysterious existence in subspace also opened its eyes and stared at humans!
