Jacob wasn't a fool. From the moment Mr. Observer reacted after seeing the titan iron and Jerry's sudden excitement, there wasn't gone unnoticed by him.
Although he had no idea, why they were so eager to purchase this titan iron, but one thing was clear there was something he doesn't know about titan iron which they did, obliviously.
Now, he had to figure out what it was.
Furthermore, Jerry clearly had no idea the Earthen Kingdom of Hob Trolls had a reserve of Titan Iron Ore, or with how eager they are, they might've already gone there to take control over that reserve by now.
Jacob still has over 120KG Titan Iron of the same quality, and if he could find out why a powerful hobgoblin like Jerry was after, he might reap some unexpected benefits.
Mr. Observer came back at this moment and told, "The total weight of the three bricks is 3090 grams. The total amount in gold, 98,880."
