I sincerely apologize to all my friends who read the book.
I posted a single chapter in the morning and originally planned to put it on the shelves tomorrow, but the editor just told me that it has entered a new round of recommendations.
So the launch time was forced to be postponed by a week.
I don't make any excuses. I'm sorry for everyone. I apologize to everyone. It's my fault.
Finally, I shamelessly begged for a follow-up study. The reason why it was so difficult to give birth was because of the follow-up study!
