How does the blood source curse the old hunter to get all the weapons?

Tell you where to pick up your weapon:

Nightmare Cathedral Area: Monster Hunter Machete, Arm of Amidala, Gatling Machine Gun, Blasting Hammer, Animal Knife, Rotating Saw Blade.

After Ludwig gave the moonlight sword.

Dungeon: Grazia's fist, bloody book, church hammer (get the key to the dungeon and open the door, and a hunter will kill you and take it away)

Research building area: church cannon (the platform on which the eyeball pendant is placed breaks the mechanism so that it can find a treasure chest, and the treasure chest is inside), and the shield of the lake.

Fishing village: Luoyang, the bow blade of Ximen (he fell on the second light and took it away directly after the conversation)

Kill orphans and give them to parasites.

Finally, the store bought a rifle.
