Bab 521: Wait

In the skies above the Mid-Grade Spirit Stone Mine that Mira's group had just plundered, a middle-aged man with bushy eyebrows and a square face appeared. His expression became solemn as he noticed headless corpses littered about on the ground.

Most of the faces on the heads showed neutral expressions, indicating that they died without even knowing how. 

"Whoever did this was quick, efficient, and skilled enough to kill almost all the disciples without alerting them. It seems they came here knowing everything about the mine, how many people were here, and even their strength." 

He muttered before looking in the distance, sensing the corpse of Elder Dan, the person in charge of the mine.

The man stepped and soon appeared right above the dissected, shriveled corpse. He furrowed his brows, but no hint of remorse could be seen in his eyes.
