I Ask You to Find a Summer Job and You Sell Spaceships to the Country?

Summer vacation is here, and Su Chen plans to find a summer job, but accidentally binds to the Nebula Chamber of Commerce system, allowing him to trade with alien races in the vast universe. So Su Chen suddenly came up with the idea that he could pretend to be an alien and become a second-hand dealer, selling alien products to his country. As a result, the country mastered technologies such as war mechas, spaceships, Dyson spheres, and stellar excavators overnight, shocking the world! Yingjiang: I'm still studying fighter jets, but your aircraft carrier has already taken off? Little Days: Stop! What the hell is your mecha army? Don't get me wrong, I'm not targeting anyone, I mean, all countries are brothers.
