Comments of chapter undefined of The Golem Mage

He could’ve use that wind element for one of his golems n save 5000 js

Also him being "secluded" from the rest of the world is making him just again stupid and ignorant. In the 14 or whatever years he has existed he did nothing? No research, no learning, no reading, no training, he is just useless for all his existence?

That was incredibly stupid. Rather than figuring out what use it has, he sells it before knowing anything about it? He didn't want to use it as golem material? He didn't want to ask the system? I feel like after all the emphasis on him being a great tactician, this just made him dumb for being dumbs sake
