Ask for one day off

Don't wait for friends who are waiting for the update. There are a lot of things to do at home today, so I can't code words, so I can only stop updating for one day. At the same time, Xiaochen should also think carefully about the details of the book. Please forgive me. It will continue to be updated tomorrow. Well, from tomorrow, at least until the end of the month, there will be no more updates.
