"Ah..."
At that moment, Jisu, who was looking at the portal, hardened her face. She looked as if she tried to see through to the world beyond it.
"Sis, step back!" she shouted.
"Huh? Why?"
"You will find it hard even to step back a little later."
At the same time, a message rang.
- The middle-level boss monster 'Guardian of the Gate of Demon's Cave' has appeared.
"He's come out earlier than expected."
"Gatekeeper?"
The 'Guardian of the Gate of Demon's Cave,' who was the final boss on the first floor of this cave, appeared as the middle-level boss this time.
Thump- Thump- Thump-
He leisurely walked out of the portal.
Krurrrrrr...
The terrifying-looking giant growled, revealing his obsidian teeth.
