Teacher, Please Take a Leave, I'm Going to Wander the Earth

Accidentally traveled across the Blue Star and became an ordinary high school student, but he accidentally awakened to the future technology manufacturing system. Ye Cheng had to take leave all day because he promised his deceased father to go to college and had to complete the manufacturing tasks specified by the system. "Teacher, I can't come today. I have to prepare to wander around the earth." "Teacher, I probably have to take a day off today. It's really urgent. I have to study what's going on with the three-body problem?" "Teacher, don't rush me. I know the college entrance examination is coming soon, but today at three o'clock I have an appointment with aliens to negotiate." "Teacher, I want my diploma. It is my father's last wish for me to go to college." "But I do have to take a day off today." "What's the reason again?" "Aliens or Trisolaris?" "No, no, no, today is the beginning of a new era." The teacher hung up the phone angrily, but the next second a huge spaceship flew by silently in the sky. This novel and its characters are purely fictitious.
