What To Do?

Wolfram was more than pleased with all he saw. He looked around more before leaving Penelope and the miners to themselves. 

He wasn't done yet. Today, he still had some things to iron out. 

Speaking of iron, its ores were also hidden in the cave. 

They truly hit the jackpot with this one. 

Hasn't he already said it?

One can spend tens, hundreds, and thousands of years mining a single cave mine before taking 20% of its resources.

Big clans and sects had had the same mines for millions of years, still yielding profits.

This wasn't a world like Wolfram's one, but a world filled with qi and mother nature's magic to always balance things out. 

If after millions of years, the cave is fully stripped of all its resources, Wolfram could guarantee that if they let it be for a while, the same resources would appear like flowers popping out from the soil. 

Of course, caves that initially had ores would face his occurrence.
