Chapter 2437: The Gemmed Door

'How easy it is to wrap the strings around the enemies when I am not occupied in battle,' I said to myself as I wrapped my strings around two Grimms at three times more speed than I usually do.

These Grimms are not weak; one of them is Peak Grandmaster, and the other is Mid-Grandmaster. Even though I am working fast, I am extremely careful. One slightest mistake would make them discover me, and I don't want to it happen, at least not before I am successfully wrapped my strings around them.

Ashlyn is standing ready. At my words, she will move and kill the two Grimms, of which one is the peak, and the other is Mid-Grandmaster.

A minute and a half passed, and finally, I finished wrapping the strings around the Grimm Monsters.
