The Retired Young Mercenary Is Secretly a Billionaire - Chapter 18: The Hell’s Gate

The inexplicable existence expands the earth and stars a hundred times, and the whole world is digitized by the game. The ancient existence began to return, and there were alien races in the chaos.

This is the struggle for hegemony between the fierce soldiers of the Great Qin Dynasty and the Yulin Army of the prosperous Tang Dynasty, and also the collision between the military soldiers of Wei Dynasty and the trapped camp.

When the Spartan Warriors met the Yellow Turban Warriors, when the Holy See’s Crusades met the Mongolian Iron Cavalry… Elephant Soldiers, Iron Buddhas, Viking Pirates… Humans, Beasts, Alien Invasions… …Who is the strongest civilization in the heavens?

Kota Sakamoto—virgin weeb, social reject, and hentai game addict—gets sucked into a perverted dungeon world straight out of Carnal Labyrinth EX, the 18+ erotic strategy game he secretly 100%-cleared.The catch?All eight of his hot classmates and their strict MILF teacher got dragged in with him.The other catch?They hate his guts.Worse still, this dungeon world is exactly like the game—every level a twisted, orgasm-fueled survival puzzle where failure means death by overstimulation, lust-monsters, or trap-triggered climaxes that literally drain your soul.He’s the only one who knows how to survive.They either listen to the virgin... or moan themselves to death.Bondage plants, lewd slime traps, fetish trials, and orgasm boss fights await—and the only way forward is obedience.What starts as reluctant cooperation turns into obsession, as each girl slowly falls for the boy they once mocked...…the virgin who’s now their dungeon master.

In a small Realm, a destitute boy awakens the Idle Gaming System.
