The College Entrance Examination Is Coming, and My Identity as a Black Tech Has Been Exposed

Imaginary world Dragon Kingdom, Blue Star. I went for a physical check-up before the college entrance examination, and I was diagnosed with cancer. I was in my prime, but I was drowned? No, no, no! System awakening, choose the biological field immediately! Nanorobot injection - specially designed to cure cancer, everyone is asking for it and is crazy about getting it. Keyan - Are you blind? It doesn't matter, no matter how blind you are, you will be cured. Hey... How did I develop controllable nuclear fusion? It turns out that I also entered the field of physics! Ye Chu is patriotic and serves his motherland! The United States once used technology to block our country, Dragon Country, and I used all black technologies to block the United States!
