Time Travel School Battle for Hegemony

What was it like to travel through time with the school? I soon realized this feeling. The people in the school are all talented people who speak well and have food to eat. If I want to stay in school and work all my life, it is impossible to work. The only way to do it is to brag and talk in school. The introduction is short and weak, please read the text.
