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

"I couldn't believe I agreed to this..." The brown-haired girl covered her face with her hand and lamented, "And I wore something... like this too. This is too tight. And these pants? This shows the world the shape of my legs! How indecent!"

"There is nothing indecent about that." Jessica commented as she crossed her legs. "We are all wearing that. And you will find it useful in your job later on."

"Putting that aside..." Leo interrupted their conversation. He walked toward Jessica and sat beside her.

The secretary moved to the side to give him some space. Her hands were holding him as if it was the most natural thing to do.

Leo's gaze was fixed on Peng Li-Yue. He snapped his fingers and grinned.

"If you really plan to throw away your past identity and join us, you will need a new name."

"A new name?" The woman asked with confusion written all over her face.
