Gwah-gwah-gwahng!

The aftermath of the explosion was incredible. Several dozen Skeleton Mages had been swept away. Woojin had been hunting by himself, so fortunately, his soldiers and Familiars hadn’t been by his side.

Hooooohng!

Nearby buildings collapsed into rubble under the shockwave. When the dust settled, Woojin retracted his barrier and approached Jaenis.

“How does it feel being released from the seal?”

[Do you think I had fun during the time I had lost?]

Woojin shrugged. He'd never experienced being in the Sealed Room, and he had never experienced death.

“You probably have a lot of questions for me. Let's tidy up the battlefield first.”

[That sounds like a good idea.]

“You should team up with Ramson.”

[I'll do so.]

Woojin quickly grabbed Jaenis, who was about to disappear, “Oh yeah. Don't kill any humans.”

[Your words make no sense.]

“Don't kill them.”

[…as the lord wants.]

Hwee-ree-reek.

Jaenis disappeared as his body turned into black smoke.

The Lich never went back on his word, so he wouldn't harm the humans. Unfortunately, that meant that the monster eradication might slow. On the other hand, he wouldn’t torch the entire house just to eradicate fleas. 

If Woojin hadn't cautioned Jaenis, he would have indiscriminately bombarded the city of Seoul.

That would have been the quickest way to eradicate all...
