Colin paused slightly, surprised by the First Rank Wizard on his left.
"How is that possible? When do wizards have such leisure time? Cave creatures aren't valuable; only we Wandering Wizards rely on this for a living. Besides, you also said that the population of cave creatures has been declining over the past ten years. The recent steep drop in the last half year is probably a normal phenomenon."
"Indeed..."
The two First Rank Wizards gradually walked away.
Colin continued to move forward, encountering several wizards exploring the cave along the way.
However, as he ventured deeper into the cavern, the cave contamination in the surrounding environment grew stronger, and the likelihood of encountering wizards diminished.
About ten minutes later, Colin stopped at a fork in the path.
The cave contamination here had turned into substantial grey-black mist, forming a distinctly divided area in the air.
This was the boundary between the shallow and deeper parts of the cave.
