After putting a suggestion to add a mercenary in a bad Murim novel he read, Leo would finish a mission with his NPCs before sleeping. 
Or so he planned.

For some reason, he was transported into the said novel as the extra mercenary added by the author. His loyal NPCs, a yandere secretary, a happy-go-lucky assassin, a sexy puppeteer, and two weapon maniac guys start to become sentient.

He lead his mercenary band 'Hallowed Insects' toward an an unprecedented future in a Murim most turbulent era while enjoying his time.

Fortunately, they still have their futuristic equipment with them. Tang Clan have a Poison Dagger, they have a Photon Sword. Shaolin Sect has a Qi Blast, they have a Railgun.

And of course...

"How much are you willing to pay to employ us? By the way, Demon Sect pay us 50,000 Golds to join their side in the upcoming war."

... he always sided with the highest bidder.

Mercenary Harem in Murim Novel

"Nnghh!!" she screamed. "It's so big! It's too much! Ahhhn!"

He pushed deeper, his cock entered deeper inside, stretching her anal passage and pushing past the tight ring of muscle. Then he stopped.

"Now then, are you satisfied? Or do you still want more?" He asked while staring at her. "If you want more, beg."

Nabi looked at him. Her expression showed the mix of shame, anger, and lust. She didn't know what to do.

"P-Please... I need more... fuck me... fuck my ass..."

Leaning closer, he pressed his lips against hers, kissing her passionately. His hands roamed around her body, caressing her soft skin, feeling every part of her body. Her hands also went to grab his, stopping his movement.
