This Kid Has No Sense of Fair Play! Building an Aircraft Engine by Hand for a Competition?

[Technology to Strengthen the Nation + Child Prodigy + Strong Moral Values + Contributing to the Country + Patriotism] Doctor Jiang He transmigrates to a parallel world as an elementary school student and gets bound to a “Technology Tree” System. The System requires him to win first place in the national science and technology competition. In return, he’ll receive Technology Points that he can exchange for cutting-edge technology. When he uses knowledge from his previous life to build an aircraft engine by hand and enter it in the competition, the entire tech world goes into an uproar. “This kid plays dirty!” “Isn’t this just picking on the adults?” “Entering an aircraft engine in this kind of competition? That’s like using a cannon to kill a mosquito!” The news immediately shakes up every academician at the Great Xia Academy of Sciences! They’ve been worrying about foreign countries holding the aviation-engine industry hostage with their technology, and now a kid has built one by hand? Foreign aircraft-engine manufacturers try to sell Great Xia engines at sky-high prices, only for Great Xia to proudly declare that it can make its own! Jiang He looks at his account full of Technology Points and all the experiments he hasn’t had time to run, and starts to get a headache. Should he complete controlled nuclear fusion first, build the world’s strongest special steel, or… Uncle Sam: “Does anyone else get it? We put Great Xia under a technology blockade. How did they surpass us?”
