Mining Slave II

I sent another wave through the method, this time even more powerful, going even deeper. 

A second later, it came back with the response and toxins. As I read it., I found there are no doras of crystal in one nine deep in one square meter area.

Even with the method, the walls are hard to breach. I would need to use considerable power to send the method deeper. Will also need to be mindful of whether I could even dig into the deeper part, even if I find the crystals.

I sent another wave and then another, going deeper and deeper, till at eighteen inches deep, I finally found the crystal.

Cling!

I couldn't help but feel excited finding the small crystal, and immediately, I hit the pickaxe against the wall.

To my surprise, I could barely chip away a small rock. Though I did not use my energy, I still applied considerable physical force. It was not enough to break these tough walls.
