The book is wet and not handled in time. What should I do if I stick it together after it is dry?

Nothing is particularly effective. You can try something a little tricky. I tried it myself, and the effect is good, but don't let others see it, it will make you stupid.

Put some starch in the water, stir well to make the water slightly turbid, and then put the book in. After the book is completely wet, gently shake it back and forth in the water, and it will be easy. Put the book at a temperature of about 40 degrees, and then turn it over a few times when it is dry. Remember not to overdo it and the temperature should not be too high, otherwise the book will turn yellow and wrinkle after it comes out.
