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

Leo shrugged, acting as if he didn't just kill someone.

Meanwhile, the others were terrified.

Another man yelled and charged at him. Leo raised his hand and stopped the sword with his bare hand. The man trembled and tried to pull it back, but Leo wouldn't let him.

"What's wrong? Can't move your dull blade anymore?"

With a wave of his hand, the sword shattered, and the man fell to the ground, holding his injured hand. Blood seeped through his fingers, and his face was pale.

"See? It's so dull and brittle that it got destroyed just like that."

From behind him, the men screamed in horror. They couldn't understand what was going on and didn't know how to react.

"Brother! Quick, attack him! We have him surrounded!"

"Kill him! Kill him! Don't let him get away! Avenge our leader!"
