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

Yue Yue felt her anus stretching around his thick shaft as he plunged it deeper and deeper, until he finally managed to penetrate her fully. Her pussy contracted around his member, trying to milk his seed out of him.

As his cock fully entered her, she squirted and pushed all the semen in her pussy out of her body. She moaned in delight. She felt so full, she could barely move. Her eyes were rolled back. Her lips formed an O shape. Her toes curled up and her back arched. Her body shook as her mind became hazy.

He started pumping his cock in and out of her tight hole, pushing it even deeper and faster than before. Each time he pulled his shaft out of her, she felt like her mind went numb from pleasure.

"Oohhh! Yes, yes! Give me your semen! I need it~!" Her voice was hoarse and ragged. Her breathing grew heavier as her body shook violently. "More! I want to be messed up more."
