He didn't know how long he had been moving forward when he suddenly felt a peculiar vibration coming from ahead.
This vibration was faint, like a gigantic monster far away gently stomping its foot, yet it persisted without ceasing.
The experienced [Geisla] instantly became alert, his ears trembling slightly as he carefully discerned the source and nature of the vibration.
He knew very well this was unlikely a sign of Abyssal Demon activity.
When Abyssal Demons move, it is often accompanied by heavy footsteps and savage roars, and those vibrations are violent and short-lived. However, this time, the vibration had a unique rhythm.
Could it be another treasure encounter?
Sila speculated with a bit of excitement in his heart.
In the Underground City, many treasures often come to life in unknown corners, sometimes accompanied by peculiar anomalies when they appear.
The last time he found an Advanced Magic Gem was within a wall cracked open by vibrations in the Underground City.
