The World Ends from the Start? The Demon King and I Have a Date

Horror Escape Infinite Flow: High IQ, High Combat Ability, Romance Optional

I'd like books similar to The Escape Game Is About to Begin. I like powerful duos who face life and death together, never let each other down, and aren't insultingly stupid

Looking for Infinite-Flow Novels with High-IQ Mind Games from Everyone, Including the Villains

Looking for a Mischievous Protagonist. No Characters Getting Dumbed Down, Just a Clever Troublemaker

Male Protagonist, No CP or Romance. Looking for a High-IQ Troll, Madman, or Riddler

Looking for books like "The Gods' Foolish Game."

No Female Lead!! Truly No Female Lead, No Romance, Read Carefully!!

Don’t recommend ongoing stories with heroines. If a story isn’t finished and doesn’t say it has no heroine, ask the author whether there is one first. For "I Became Invincible After Rejecting the System", the author said it has one heroine, so absolutely do not recommend it. The requester really will get mad.

I Really Want to Read a Dungeon-Based Infinite-Flow Novel That Isn't Idiotic

Horror or not is fine. No System, please!

Looking for Cerebral, High-IQ Stories. I've Been Enjoying Them Lately

Looking for a battle of wits between the protagonist and the antagonist.

Looking for No-Romance Novels With Mischievous, Cryptic, or Unhinged High-IQ Protagonists

A Pleasure-Seeking Trickster, an Elegant Madman, a Deceiver Who Toys With Everyone

Looking for books like The Fool's Game of the Gods. A smart male-oriented novel, preferably with an organization, a protagonist who defies fate, and a BKing.
