Martial King's Retired Life - Chapter 15Book :

Another entry in what you can call the Proto Harem Series: the books written before the Harem Series that take place in the same world.

It’s about a swordswoman whose student is captured, so she goes to rescue her.

An ordinary high school boy named Max is in his basement watching porn and masturbating. When suddenly, a pop-up ad covered the whole screen!

She is the underworld Ghost Doctor’s only disciple, who accidentally transmigrated into the body of the main wife’s daughter in the general’s mansion. She used to be a punching bag.Now, she stepped on her dregs of an older sister, put her father’s concubine in her place, and teaches any objectionable aristocratic ladies a lesson.

Her days are rather free and unfettered. But when did that cold as ice prince from the rumors, sporting a deadpan face all day long, fix his gaze on her?
He unexpectedly fawned and pandered to her like a devoted dog?

“Go away, you rotten man! Careful or I’ll needle you like a pin cushion!”

“Wife, why are you so fierce? As a husband, I’m so scared”
….the man is all smiles as he approached, his eyes gleaming with a cunning light.

Where does the game end? Where does reality start?

When one very anticipated VRMMORPG was about to be launched, and Jake was one of the first players to have a chance to access it, he had a weird dream of himself fighting massive beasts and then seeing a world being destroyed.

Without knowing any better, Jake assumes that it was just a weird dream, but then he begins to have those weird dreams again and again until they become even more vivid, and much to his surprise, whenever the dream changes, he obtains a new power inside the game.

It doesn't take long for Jake to realize that he isn't the only one who has those dreams, and soon enough, Jake realizes that the game and reality are a lot more connected than he thought.
