A creature had crept up behind Han Sen, unbeknownst to him. The egg struck its arm and then bounced away again. The bouncy ball was around the same size as an ordinary fist, and it bounced around from enemy to enemy but didn't hurt any of them.
"I've spent all this time and energy to produce this? This is what I get after all my hard work?!" Han Sen was heartbroken, seeing no benefit to the geno core he had earned.
"Whatever; I'll continue on my way to that pit." Han Sen put the crystal egg away and got moving.
The creatures the egg had hit continued going for Han Sen, just as they had before. This, to Han Sen, proved it was bona fide useless. It was a waste of space.
As Han Sen made his way to the hole in the ground, he slew countless beasts in his path.
