In the Battle to Defend the Earth, I Start the Mecha Era!

Scene one: The professor picked up a sophisticated advanced mecha in the battlefield! Shocked and angry. "Who did this good thing!" "You actually store such important research results in a recycling center?" Lin Xuan: "..." This is just a piece of shit I threw! Scene two: Missions from various countries rushed to dispatch to China. There are a lot of spies hidden inside. They do not go to scientific research bases or important military towns. Instead, he headed straight to the abandoned ***** field! "Don't snatch the defective products that Academician Lin Xuan threw away from us!" "Are you going to start a war?" … The polar civilization from the Centaur Galaxy launched a war of aggression! Hitting and hitting, they felt something was not right. "Why are human mechas more powerful than ours?" "Oh my God!" "They actually developed a Star Destroyer that doesn't even exist in the Centaur Galaxy?!" "This is the legendary two-way foil of destructive technology that is only available to the most advanced civilization in the universe!" This novel and its characters are purely fictitious.
