Qin Fan explained the mecha in the live broadcast room, but was targeted by the military factory. As the mecha was built, the entire scientific community and military were shocked. Everyone: "Then... Is that an alien? Are aliens coming to invade?" Qin Fan: "No, that's not an alien, it's a mecha I built!" Academy of Sciences: Mecha? Aircraft carrier? Space elevator? Starship? Biological armor? Did you develop this? Qin Fan: Well, it's me. I just made a few things for the country. How come I entered the interstellar era?
