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.

Fortunately, he didn't have to waste any more time. The analysis was done and the antidote for the mental corruption was sent to him immediately through the Main Cube.

And he also finished analyzing the enemy's secret as well as her weakness. His computing speed increased as he used lightning Qi to boost his nerves, and he smirked. His Nanites used the information sent by Chiaki to render the fog's effect useless.

"It's my turn now." He said as his hands began to glow in blue.

Electricity crackled around him. His hair slowly rose and turned white. The atmosphere around him changed as if he was a human lightning bolt, dispelling the fog.

He disappeared from where he stood with a flash and reappeared behind his enemy.

"How..." The girl couldn't finish her word.
