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.

She murmured happily as she hugged his body, letting him lean against her body and holding his head with both arms wrapped around his neck. Leo closed his eyes and kissed her. Her tongue tried to pry open his mouth before moving inside it and enjoying her taste while savoring everything he could from her.

The scent of strawberries lingered on her smooth lips. A cocktail, he guessed.

After a while, they parted and Jessica smiled softly.

"Come on. Let's settle our business first." He said as he broke away from her arms and started walking towards the cliff edge. "We have a lot of things to do."

"Fufufu, yes. I'm looking forward to it."

She chuckled happily and followed after him. Her hands didn't leave his arms.
