A little bit about the update here.

Because I recently had to prepare for an exam, which was difficult, there was a lot of content, and I didn't have much time, so it was next weekend. Now that I review until the wee hours of the morning every day, it's really hard to find time to code words.

So the next week of updates will not be very stable, here, I want to say sorry to the book friends!

But I promise,After the end of the exam, that is, a week later,The update will be strong!At least two changes a day,Three changes are possible!Finally,Thank you for your support!
