Diablo 3's national service "pursuing freedom" task?

1, first of all, you have to have at least one set (or six sets with bonus effect), such as the Wrath of Waste Soil (Waste Soil Set) worn here.

A 1 New Tristram, "King Leorik Manor Courtyard" in the lower left corner. After entering, go up the stairs to the second floor and pass the "Royal Bedroom" to the library.

2. When you see the "dungeon collection" on the table, it will drop when you touch it, and the collection will be broken. I'm wearing a wasteland cover, which corresponds to 22 pages.

3. The entrance to the underground city is described on the last page. If you know diablo 3 well, I believe you can guess where it is. For example, the "old and crazy fortress" mentioned on page 22 here, the possible location is A5, the chaotic fortress. You have to find out for yourself. Different players may get different things.
