Altar

A Desert Demon with a level in the mid-30s facing an Incarnation with wisdom controlling a first-rate True Spirit Magic Tool. He wasn't an idiot; he knew that the best course of action was to remain silent and act as if he didn't hear anything.

Enderfa laughed at Slythrin for a bit before getting bored since he couldn't get any reaction from the mute Slythrin.

Slythrin waited on the side and made himself look as insignificant as possible while he calmly waited for Lin Yun to finish burning the desert.

As time passed, Slythrin understood that pieces of golden metal were mixed within the burnt desert.

Slowly, the amount of lava reduced, and more of that dark golden metal appeared.

This time, Slythrin finally understood that Lin Yun was refining metal, treating the desert as a one-time use mine. 

But after seeing this, Slythrin felt more and more that his decision had been very wise.
