https://www.webnovel.com/book/11766562205519505/Endless-Path-%3A-Infinite-Cosmos Endless path Infinite Cosmoss, fanfic about danmachi, didn't think I'd enjoy it as much as I do right now, author uploads 30ch/week (and those aren't tiny chapters either). Argueably better writing then Danmachi itself. Just be prepared that tough he is planning to incorporate more worlds in the future, he is setting Danmachi as the main world. He is at ch 860 at the moment I write this and still at the first world. (which is not a bad thing imo)
https://www.webnovel.com/book/7211215605000405/The-Ultimate-Evolution The ultimate evolution is a novel where the mc goes to movie worlds, completes their mission and in return earns rewards to get stronger. Mc is also the scheming type that actually has an author smart enough to make plans that not everyone will see coming.
https://www.webnovel.com/book/7736629105000905/The-Devil's-Cage The devil's cage is a novel about an "underground game" where if you die in the game you die in real life. This is imo not a vrmmorpg novel, mostly singleplayer dungeons with a few multiplayer ones, the upgrades and boosts the mc get are great to read. Besides that, another mc that likes to think this out and act well in situations where there are schemes against him. Just another solid novel
https://www.webnovel.com/book/11236791006300205/Chrysalis Chrysalis, solid novel, user reincarnates as an ant, has to defeat monsters for xp and eat them for body part upgrades. Has skills, special effects at certain levels and a pretty funny protagonist.
https://www.royalroad.com/fiction/12798/shovels-in-spades Something not on this site since it's an original of royalroad. It got recommended to me by someone and I absolutely love this one. Mc is a cold calculating person who get's dumbed into an apocolyps by "the system" together with the rest of the world. Those that had anything in their hands that could be defined as a weapon would be alive while those that had nothing in their hands all died and became monsters. Everyone will have to survive waves of monsters and finish quests where they get points by doing so, allowing them to buy upgrades. MC is also a bit mental so it's definetly fun to read.
Alright that's what I have to offer to you guys, hope some more people will put some good recommendations up here that fit the genre I put up and atleast meet the requirement of 100 chapters (or close to it)
