Sorry for the update for a few hours tonight
I struggled for a whole day, and the content I wrote was completely ineffective, and the fundamental logic was wrong.
The most uncomfortable thing is that I found out that it was wrong after I finished writing it, and I had to delete and rewrite it.
It is too uncomfortable to rush every day without saving the manuscript.
Sorry, I can't update it at 6 o'clock. It's too late. Let's watch it before going to bed.
