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

In Chengdu, Jessica was sighing. The plan to create a new business came into a halt due to the lack of funds. She realized that creating a shop wouldn't be as easy as she thought it would be.

Preparation cost money and her plan was not an exception to that. Buying another land and creating a new entertainment place required a lot of money she didn't have.

"We don't have enough." She sighed again in regret as she looked at the blueprint for the place she wanted to build, "Unless we can get some loan from banks, we can't proceed with this project. But is there any bank here? I don't think so."

The plan was to create an entertainment place with the theme of gambling den and modern bar where bunny girls serve alcoholic drinks. They also wanted to recruit beautiful girls for this place to serve the customers while becoming idols for them at the same time. This combined both the modern and Murim world into one place.
