The next mission?

At first, the mutants looked to be a little hesitant, however, they still reluctantly walked forward and gave up their beads, placing them on his hand one by one. 

Hecathe yawned as he started counting the mutant beads and he seemed to have already realized that this was going to at least take him a couple of minutes. 

After a few minutes, when the hundred mutant beads had been collected, Hecathe ordered for them to stop and put the mutant beads down on the floor before taking a rock and smashing the beads with it. 

By hitting them with the rock, he was turning expensive pure mutant beads to normal collected mutant beads that could indeed fetch you some good cash but would still be a lot cheaper than the pure mutant beads. 

If one were to see him doing this, they would certainly be forced to believe that he was a madman and they would fail to see through his plan.
