On the first day back to school, since several previous classes had just entered the stage of acceptance homework, I had to rush hard... When I started coding in the evening, I couldn't hold back anything for more than an hour (that's what I did before)

(Half of the chapter is saved in the manuscript), so that’s it for today (Friday). There is no experimental class on Saturday this week, so Orange will add another chapter to make up for it.
Chapter completed!
