Of the over six hundred gold rank assassins in this place, at least six hundred were screaming in agony.
Some, having endured too many punctures, were shaking uncontrollably. However, with each tremor, their bodies only suffered more tiny bloody holes. Thus they continued to scream, continued to shake, continued to accumulate more holes infused with blood...
Some particularly unlucky ones, had...ahem... sharp objects lodged in their lower part, and their screams were simply earth-shattering.
"Laugh? I'll make you laugh! Don't you know suppressing emotions is the basic rule for assassins?"
The instructor cynically paraded back and forth, a cold gleam radiating from his golden mask: "You think you've come here for training to laugh? Huh? I think you're all here to perform comic acts!"
