As he was about to start working on a few axes, and other common tools he would need around his new smithing lab, he sensed two presences approaching.
~Alpha and... Zhayen,~ he thought to himself without so much as taking his eyes off the work he was doing.
That was the level his earth sense had now reached. Not only could he tell the threat level of the beings he was sensing, but he could tell other things now as well. For instance what size they were, how much energy they were carrying, and if he focused a little more, what kind of mood they were in.
Even though his earth sense could sort of tell all this before he had started making more progress towards evolution, it wasn't as pronounced and would've required him to spend unnecessary time trying to figure these things out.
~Wait, earth sense, that's it,~ he thought to himself, walking towards the curtain that acted as a door to his room, before drawing it for his two guests.
