Sorry, everyone. The cat began to have a headache from getting up in the morning today, I thought it would be better in the afternoon and evening, who knew that the headache was getting worse and worse, sitting in front of the computer to prepare code words, but the brain was blank, a little move the brain, I felt that the headache was terrible, and I didn't code out a chapter until now.

The cat can only say sorry today, take a leave of absence today, and continue to update tomorrow. (To be continued......)
