To give you an idea my favorite novels are supreme magus and second coming of avarice so i like a bit dark or more mature novels. I don't want any harem bullshit i don't care if it is a gaming, isekai or whatever type of novel it is. I just want a good story with some characters with personalities i can relate. If it has 200+ chapters that would be nice too
Need some new novels to read

HolyScheisse U CAN try LORD OF MYSTERIES, AND RELEASE THAT WITCH (IT HAS SOME ROMANCE CONTENT THOUGH 5-6%)
BOTH ARE BEST NOVELS AT LEAST FOR ME 
BOTH ARE MYSTERIE RELATED , CLASSIC THE BEST STORY PLOT, AND DIFFERENT FROM THOSE CULTIVATION NOVELS, U CAN CHECK REVIEWS FOR REST
I have read a few similar titles only one that comes to mind right now is "curse the mainframe"
Will add if remember more....
Not sure if you'll like this but I tried to make it as dark as possible.

Genres: Comedy, Xianxia, Action, OP Lead, System, Business
In a remote alleyway stands a store. No one truly understands what it is selling, but people traverse it anyway.
"I hear the place fulfills your wildest dreams," says a female who wants to remain unnamed. "People who enter never wish to leave."
"The store-owner is a jerk—the prices are expensive, the staff is rude and you serve yourself," another male explains, "what, I'm still going though."
"I'm just here to look at the cute girls," says—well, his opinion doesn't matter, anyway.
"Listen, whatever you do, don't mess with the immortal siblings there. Who that is? The store-owner and his sister, of course! Why we call them that?" The person shudders. "Because we couldn't think of a fiercer name yet."
Welcome to the Store of Fates! Dear customer, would you like to change your destiny too?
Please try out my novel, A Bend in Time.
https://www.webnovel.com/book/14576125306898605/A-Bend-in-Time
Before there ever was a boy that ever lived in a cupboard on Four Privet Drive, there was a similar boy in a far worse home that lived on Spinner’s End. We all know the tale of that abused boy who grew up to become a bitter spy. But not all tales end the same for in the many parallel worlds that exist in the universe there are far better endings, and equally as many worse ones. This is a tale of one such condemned universe that for better or for worse choose to change its own fate.
HolyScheisse Could give my novel a try but it's not dark and such. No harem building.
Title: New Life: A Second Chance
Synopsis: This is a rebirth story of a normal girl, Kylie and reborn – as a boy. Grow with her/him as she/he learns how to live one life (as a boy) and settle her past life (as a woman who left behind two kids).
Warning: MC is OP because personally, I like OP characters. /heh
It's not your typical gender-bender situation as the female is reborn as a male. Also not your typical reincarnation novel since it's a slice of life.
Genre: Magical Realism

HolyScheisse Just read 'Everybody Loves Large Chests'. And no, i'm not kidding. It has nothing to do with lumps of fat that first comes to your mind. It is about a chest monster(mimick) that quite likes the taste of humans, and gets itself into all kinds of trouble in its quest of finding 'tasty' things. Novel has quite a bit of chapters too, and the chapters are damn long compared to other WN. It would be about 1500 chapters long if compared to an avarage WN. So it will take you a good ammount of time to catch up for sure.

Hello everyone! ♪～(´ε｀ )
I realized that webnovel has many many talented writers, and definitely many avid readers.
I have spent a lot of time writing something that is dear to my heart. So I need genuine reviews for me to write better.
I'm so tired of Cinderella sisters, with mighty CEO and face slapping. My story is for the calm and silly romantics (like myself 
)

Mature? Well... The casts are mostly 20+ of age (and I plan to continue doing so) so this novel could be of interest to you. But it's still less than 100 chaps.

Lmao not sure whether you're genuinly asking for novels or making place for people to promote their own. So, I'll do both:
Some good ones are:
ISSTH, RI, generally all of Er Gen's Stuff, Chaotic Sword God is pretty good if you look past the short chaps.
Now for self promotion copy pasta lmao:
