Drekk was shown around by Byung, but it was a goblin's nature to be deceptive, so Drekk wasn't particularly worried about his trickery as long as it wasn't malicious in nature.
Byung explained in detail what these were, including what they were capable of making.
Drekk had the same question as anyone who came into contact with this.
"How did you make these things?" Drekk questioned, but Byung knew he couldn't tell him he reincarnated into this world with a freaking system.
"I just knew… There are a lot of things I know," Byung said, and Drekk didn't push further.
He wasn't the smartest—if anything, he was dumb even by goblin standards—but his instincts were what set him apart.
He knew he wouldn't understand if Byung explained the mechanics of it, but it was clear this thing could help make weapons.
"The human… Did he see it?" Drekk questioned, and Byung froze for a second, not sure what to say at that moment.
