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 was one of the six. And from these six people, one would become a leader. The other five would be the servants of that leader. They had no right to oppose the leader, they must serve the leader obediently."

A truly bizarre rule that made him feel strange. Was the sect leader that great of a figure? Why did they need such strict rules?

"I don't know why, but there are no women in the history of Hao Sect's leadership." Nabi chuckled. "So I thought I was out of the running. But that didn't mean I was free from the ceremony. I am still a potential servant, after all."

She turned to the side and took the glass of wine on the table, sipping it slowly.

"Being a servant means my freedom will be taken from me. I don't want that, and I am sure the rest don't want it either."

Putting the glass on the table, Nabi leaned her head against Leo's shoulder and continued. Her voice sounded pretty weak and... pitiful.
