Now turn back, grab this item, and jump straight down.
After jumping down, there's a purple item in the middle of the chest on the right.
You can talk to the self-destructing胖子 (Fat Man) ahead. After the conversation, keep your distance and wait a moment; it will explode on its own.
After it explodes, collect the materials.
Let's head left now; you can pick up some Dust in the corner ahead.
Follow the uphill path on the left all the way up, defeat the enemies here, and then head right. The area on the left is where we jumped down earlier.
There's another book around the corner on the right path: [Various Votive Texts #4 Wang Yiren's Votive Text].
