The 战力 of Earth

What's wrong with this? I wonder if the Fire Crystal is too strong. The machine doesn't work well. It may be overpowered, but I can't stop here. This is a moment I have to use my brain. Well, we need a power opposite to Fire. I have one in my mind. The 战力 of the Elementals is very strong near the Elemental Water in the west. The 战力 of the Earth Elemental crystallizes in the ground. It's totally different from Elemental Stone, and is generally called Earth's Eye. You should bring it to me. Bring Earth's Eye from under the rock west of the Elements Waterfall.

Don't you think it is a good idea to keep balance between powers? The machine is now screaming, so bring me Earth's Eye from under the rock west of the Elements Waterfall.

Oh no! It blew out even before you brought it. I have to start again from scratch. I don't have magic jewels that can power the machine at the moment, so it will take a while. Would you help me again? Ha! Ha! Think of it as a valuable investment for a great invention. Anyway, thank you.
