[This is a story where you treat them as your competitors, and they treat you as your first love + tame dye] Your name is Xuexi Zhishi, you are a social animal, you have just traveled through time, and you like to mention the system. System: As long as you get first place 5 times, you can go home. First. You become a primary school student. You: Am I going to become a primary school student with an adult's head and a child's body? Wait, how come someone wants to build their own rocket at the age of 8? The script is wrong! Senku: You also like science and the universe, right? Second time. You came to America, military academy. Your opponent is a handsome blond boy who has perfect scores in physical combat and shooting. You: I just finished torturing my culture class and now I'm going to torment my physical education class? Stanley: Huh? Than shooting? The third time. You became an elementary school student again, this time being taught by a private tutor from the chaebol. You: Why is the 9-year-old kid sitting next to me studying advanced mathematics? Why is that 4-year-old studying finance? Sai: .... Programming is fun, right? Long Shui: I want it! ! The fourth time. You returned to the United States to attend college, majoring in aerospace science. And this time, one of your classmates is a 10-year-old genius who skipped a grade. You: Scientist again!

You who have already taken out your books and prepared papers to study:? * Question: How do ordinary people become academic masters? Yuki Kiki: Have you ever heard of a study room where the flow of time slows down, a pen that cannot be let go until it runs out of ink, an exercise book that means you will be unlucky for a hundred days if you don't get everything right, and a practice range that turns you into a target if you don't hit the tenth ring?
