I have read alot of novels i enjoy some Harem aspect. I liked Death March kara hajimaru isekai kyousou kyoku, Long Lived Summoner, The New Gate, So what if its an RPG world.Xianxia novels are fine. The thing i hate the most is betrayal. I like novels where the mc always suprises other people with either their strengths or superior knowledge.
Reincarnator Tales of demons and God Sovereign of three realms Otherworldly Evil Monarch The Nine Cauldron Basically every xianxia out there
These ones have really crazy OP MC. The GM Has Logged Into A Different World Isekai Cheat Daily Transfer ~I Will Be Peerless in Every World~ Another World’s Savior ~ I Became Unparalleled by Using the Jet-Black Divine Equipment~ Ex-Hero Candidate’s, Who Turned Out To Be A Cheat From Lv2, Laid-back Life In Another World Kujibiki Tokushou: Musou Hāremu ken Skeleton Knight, in Another World Isekai Shoukan Makikomu Ijousha Evil God Yuusha Party no Kawaii Ko ga Ita no de, Kokuhaku Shite Ultimate Antihero Higawari Teni ~ ore wa arayuru sekai de musou suru ～
hello! -historys number 1 founder it has one if the best MCs i've seen in xianxia/xuanhuan! and he does continue to get stronger and stuff. -yaonie bing wang the MC ks already strong, and it has a bit of the harem aspect, yes-- -dominion's end the MC trains to become strong, though it's not entirely focused on it yeah, most xianxias have the MC training to become strong...and a number of them have the harem aspect too...
https://mike777ac.com/hardcore-op-ness/ MC is the only player in a WoW-like game world. MC does acquire a party (which does become his harem) of adult non-human female NPCs. However very frequent and explicit sexual content (the characters are all OP power gamers and having sex is one way to increase stats so ...). http://www.novelupdates.com/series/arifureta-shokugyou-de-sekai-saikyou/ MC is abandoned by his classmates in a fantasy world. Survives and becomes OP and builds a harem on his way to determine a way back home. http://www.novelupdates.com/series/god-and-devil-world/ Our modern world becomes a zombie apocalypse game world. MC slowly gathers survivors with his strength to try to rebuild society. Very dark setting with explicit scenes of mindless killing, rape, torture, sex slave, exploitation (such as former collage student selling herself for a cup of ramen noodles), etc. http://www.novelupdates.com/series/remonster/ MC reincarnates as a goblin with a special OP power. MC takes control of his tribe, converts it into a mercenary group, and starts to influence surrounding nation. The MC is considered the big bad in this setting (and is considered a living god). Some 18+ material but typically not explicit. https://yoraikun.wordpress.com/tny-chapters/ MC is summoned as one of four heroes but his weapon is the shield. Get royally S***wed over and forced to correct the problems of the other heroes. In the process, MC becomes the greatest hero (and OP) of all time. Death March was greatly influenced by this complete story.
Invincible Saint(he trained hard because he doesn't want to die.) Legendary Moonlight Sculptor(he trained hard in real life to have a body that can move fluently when fighting in V.R.) Martial Peak Perfect World(this guy really trained hard to become strong, since he was a kid.)
