There is a 515 crazy flip in the activity, the starting point reading client, the lower right corner of the bookshelf and other places can be entered, after entering, find a 'grab' word, click in, and turn the page like a book, you can grab it.

Note that it's not the page of the book, it's the page that is "full of greetings for the 14th anniversary of the starting point" after entering, and you have to keep turning the pages like a book.

After experiments, it is best to grab on the hour, you can grab about ten in one breath, there are 515 coins of the big bag, grab a few more times, you can basically grab the big bag, after the hour more than ten minutes can also be grabbed, but not so dense on the hour, after a quarter of an hour on the hour, you can basically not grab, you can only wait for the next hour to grab again.
