Lily sent all of her ground golems into the tunnel.
However, only one of them was at the very bottom at any given moment.
After all, they couldn't possibly fight a Metal Elemental.
If a Metal Elemental appeared, it would destroy everything it found.
In this case, that would be the sole golem Lily had sent to the bottom.
The remainder of the golems mined ore out of the walls of the tunnel.
Sure enough, after just one hour of mining, Lily lost contact with the golem at the very bottom.
Due to the distance, she didn't get any detailed information.
She only knew that her golem was destroyed.
It could only have been a Metal Elemental.
After that happened, everyone waited for an hour.
Then, Lily sent the next golem down.
It didn't immediately die and continued where the first one left off.
While the golem continued mining, Lily used the freshly mined ore to create more golems.
Even better, the abundance of high-quality ore also allowed her to make better golems.
