The Secret of Silk Thread

I'm researching processing spider webs more finely, but they snap and split. It's really not easy. And I remember that spiders weave spiderwebs with their legs. I'm thinking I might be able to figure out the secret if I have a look at spider hind legs. However, as you can see, I'm too busy with managing the trade goods and cannot go by myself. [Character name], can you please help me? Please get me some Stone Hole Spider and Young Spider Hind Legs. You've defeated Desert Crabs easily, so I can trust you with this, too.

When you deal with Stone Hole Spiders, look at the Spider Dens nearby. You'll be in trouble if the spiders suddenly surround you.

You've gathered all the legs! Thank you so much. These will really help with my research!
