It's purely cool writing. If you don't read cool writing, please find a mirror and look at yourself. Hahaha. The author doesn't like hydrology, nor does he have that idea. Some authors in the lower world can even write hundreds of chapters. It seems that it is not as interesting as writing by yourself. The brothers and sisters passing by will support you if you have money, but you will support yourself if you have no money. Thanks, what I said above is a joke, don't take it seriously.
A good book delayed by its title
