Keep killing goblins to test. If you get more, then you'll just need to farm.

As for the building, you need some item specifically, I got one for finishing a quest, It should look like 生産技術の本

Rank 2 yet :/ I guess the enemy was goblins but I'm not certain, also I have the materials to lvl up but I just won't let me :/

Dude how do I get the ナルフム? I mean, I got some, but it's really hard to get, should I go for a certain mission? The last missin I have is the Facility Level Up, idk what that is :/ all I'm doing is the other mission to try to complete this one, ami I doing this right?

Welcome! Always remember to find a little time each day to be yourself.
