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

All kinds of business in the Capital was finished.

However, Leo stayed in the city for a full week because he had to take care of Yue Yue and gave her some briefing. Jessica played a big part to teach her and fix her appearance.

As a result, she was transformed from a prostitute to a young woman with a slender and elegant figure.

Her long gray hair was tied in a ponytail, and her pale face was clear and beautiful. Her body was soft and curvy, and her small breasts were hidden under a thin shirt.

Because Leo had expected to recruit some members, he also brought a low-level bodysuit that could be worn without needing Nanites in one's body. It was a slash and bullet proof, better than some artifacts spreading around.

So, he gave her the one that fit her body and new clothes, so she could look decent and professional.
