Anyone know how to get Nanban pistol? I kind of screw up with the trade. Just spend the ration to buy 20 forged stone to make ultimate Nanban pistol for my UR nobunaga, but I didn't scroll down to see that it need 2 Modified Nanban pistol as well. Now I need to make it which require Nanban pistol. I just keep forgetting to scroll since other games usually have page.
