Tracked [1]

Jumping to his feet Arvell looked at the direction at which Sepis was sent to scout.

'Sepis didn't deviate into any of the nearby branch tunnels yet, so if they found him, it means that they have a clear path to our location.'

Arvell furrowed his brows in confusion.

'This means that somehow they got extremely lucky by guessing our path, or… They're tracking our location.'

However this didn't make sense to Arvell.

Slimes don't have eyes, noses, or even ears, meaning that their ability to observe their surroundings is fairly limited.

They mainly interact with their environment is by emitting trace mana particles onto their surroundings, and visualizing their environments through a means similar to echolocation, or by simply observing the mana flow of nearby organisms.

If they were to be tracked it would be via the second method.
