But this doesn't sound good at all...
I don't know about the common standard of web-novel readers, but I think we shouldn't belittle them to the point that we need to chew and spit out simple sentences. The same goes for the paragraphs. I personally don't understand why people always recommend it.
Generally speaking, text flows better in small paragraphs. It's not belittling the readers, it's simply trying to make your novel the best it can be, and that includes making your paragraphs be of small easily digestible sizes.
To give an extreme example, back when I was in uni, it was common to see pragraphs that lasted from half a page to one page and a half. Those paragraphs sucked. You often lost the train of thought and had to re-read because the author lost you.
That's horrible garbage-tier writing that no editor should have ever allowed, but that was the norm for the books I read in uni. Really long paragraphs that flowed horribly and didn't lead to a smooth reading experience.
Writers of academic texts can make do with being garbage-tier writers because the people reading their books don't care about the quality of the writing itself, but about the content of the book... Webnovel authors don't have this luxury. If you write garbage, people won't read what you write, no matter how interesting the content might be.
Granted, this is an extreme example, I never saw anyone making a webnovel paragraph that was as long as one and a half pages of a book... We aren't that insane and have a basic notion of what is too much... >.>
Still, fact is, your book will generally flow better if you avoid excessively long sentences and paragraphs. Use them if necessary, but avoid it whenever possible.
