I Built a Robot Dog, So How Did It Become the Grim Reaper of the Battlefield?

[High-Tech] [Exposé] [No Romance] [Protagonist Never Appears] [Feel-Good] After transmigrating to a parallel world, Zhou Yang developed several electrical devices during college and kept them in his dorm. The school banned students from keeping cats and dogs, so dorm supervisors were sent to conduct a large-scale inspection. To raise students' safety awareness, the school held an exhibition of prohibited items. During a search of Zhou Yang's dorm, they found a mechanical dog. Teacher: “Whose toy dog is this? And why does it have a steel pipe mounted on its back?” After the mechanical dog breathed fire, the school called the police. When the officers couldn't shut it down, they had no choice but to report it, setting off an alarm at the Dragon Nation Academy of Sciences! When a group of experts and professors arrived at the exhibition, they were beside themselves with excitement. “Is this an amphibious combat robot dog?” “What if we swapped out that steel pipe and put a missile on it? That'd be terrifying!” “The question now is, how do we shut it down???” The military: “What other features can we add to this mechanical dog?” Zhou Yang: “Add a music module and have it play Find a Friend and Good Luck Is Coming on repeat. It'll wreck enemy morale and strike at their very souls!” Zhou Yang: “We could also add a voice-recording module so it can imitate the enemy and lure out hidden troops!” What a battlefield King of Hell!
