You didn't "die" so much as you employed STA to get to Map 0.0 to reset your stats.
After you left, I logged off. The Blood Worm appeared as soon as I logged back on a few minutes later, you were long gone, and they attack everything around them at the same time. In 2-3 seconds it was over. You had nothing to do with it.

However; I'll buy them off you if you got them already.
