"What was that?" Kyuri moves closer to Kang Si An instinctively. That sound is scarier than dealing with a time-crystal plant monster's scream.
"See the miasma is born from Kwak In-Sik's darkness and unholy near union with Yoon Miran." The Keeper furrows his brow a bit, not losing his calm demeanour. "It's been metamorphosing into something monstrous. Something must have triggered Kwak In-Sik. He wants to merge completely with Yoon Miran's soul forcefully and control her body."
The two humans become quiet, unable to digest what they are hearing. They turn their head together and look at the closed door. They can't tell what's on the other side. They don't have enough brains to imagine the monster either.
"Come on." Kang Si An pats Kyuri with a pale face. "It's not worse than the time-crystal monster. Remember human bones? Haha... we literally walked on human bones to that thing. My body was even sucked dry. I didn't feel a thing."
