Little Brother Doesn't Talk About Martial Ethics! Hand Rub Hangfa to Participate?

[Strong Country Technology + Child Brother + Three Views + Handing Over to the Country + Patriotism] Doctor Jiang He traveled to a parallel world and became a primary school student, and was also bound to a "technology tree" system. The system requires him to win first place in the national science and technology competition, and then he can obtain science and technology points and exchange them for black technology rewards. When he used his pre-travel knowledge to build an aircraft engine and participate in the competition, the entire technology circle exploded. "Little brother doesn't have martial ethics!" "Isn't this bullying adults?" "Participating in this kind of competition with an aircraft engine? How is this different from using a cannon to kill mosquitoes?" As soon as this incident came out, all the academicians of the Daxia Academy of Sciences were alarmed! They were also worried that the aerospace field was being suppressed by foreign technology, but they were rubbed by a kid brother? Foreign aircraft manufacturers also wanted to sell Daxia engines at sky-high prices, but Daxia responded domineeringly that we can build them ourselves! Jiang He started to have a headache when he saw that his account was full of technology points and there were also technology experiments that he had no time to do. Should we complete the controllable nuclear fusion reaction first, or build the world's strongest special steel first, or... Yingjiang: "Who in the family understands? They have blocked Daxia's technology? How did they surpass us?"
