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

Evacuation immediately began. The citizens who had been staying inside the evacuation hall were confused as they were guided to the West Gate by the Bloody Guard.

"Move orderly! There is no danger at all. We will move to a better evacuation zone. Please everyone cooperate and let's move quickly!"

The guards shouted and urged the citizens to move faster. The East Gate was out of the question as it was filled with the enemy, and they had no choice but to go through the West Gate. The citizens looked confused and scared, but they knew that they couldn't stay in the city any longer.

Leading them, the Bloody Guard's commander, a man named Yang Gong, was giving out instructions. He was a man with a broad body and a face full of scars, which showed how many fights he had been through.

With him, the Bloody Guard moved like a well-oiled machine. They surrounded the citizens and kept them from falling into chaos.
