Jem was quite surprised by what the trader told him.
Inside the labyrinth, the monster's body would never disappear when he killed them. That's why it surprised him when the gobs turned into smoke and disappeared.
That's when the trader told him about their source of existence.
So, according to the trader, once the dungeon disappears, the monsters from it also disappear in a few moments.
After leaving the site where the dungeon appeared, he arrived in the market area. While walking along the street of the market, Jem suddenly stopped on his feet when something came into his mind.
The trader's voice resounded at the back of his mind.
'No, I just thought about it. When I defeated the Giant Gob in that dungeon just now, the dungeon disappeared. But when we defeated the 3-eyed guardian in the labyrinth, the labyrinth became my dimensional abode instead."
