A chance!

Ace quickly came back and expect a large movement from the golem army, but to his stupefaction, those golems were remained undisturbed. 

Truth to be told, he expected those golems or whatever controlling them would send some kind of scouts to investigate the stone golem leader's death, but it appeared that golem leader was just irrelevant. He even bothered to destroy the evidence to hinder the enemy.   

Frustrated, Ace quietly returned to his new hiding spot and waited for the cycle of one week to complete. Now his only hope was the proprietor of this golem army might react when the group did not come back when it supposed it. 

But Ace didn't sit idly this week, he eliminated more stone golems groups to make the final disturbance much bigger and complete his remaining EXP while he's at it.
