The Brilliant Ancients

Seeing the spray of ancient arrows ruthlessly shooting at the spaces now everyone couldn't help swallowing hard. 

Death to those who disturb their slumber. 

The words echoed within their hearts like warning bells. 

"This..." Lieutenant Harvey paused, throwing his head behind his shoulders. "Doc, do you think that's it?" 

Taking out his handkerchief, Ashaku wiped the pale droplets of sweat on his forehead. "I'd say 3 times is the charm, wouldn't you, 'Leftanant'?"

"Fair enough... Better safe than sorry." 

(*Ashaku and several others pronounced Lieutenant as Leftenant.)

Taking out several more perfectly weighted and rounded rocks from one of their backpacks, several people handed them to Harvey one by one. 

3 times is the charm, but why not test a higher number? 

The rocks they used were made of cement for good weight. 

Although heavy, if it can save their lives, why not pack enough? 

Bam! Bam! Bam! Bam! Bam!~
