How to unlock the tevi achievement? Some friends may not be sure about this yet, so let’s take a look at the detailed achievement guide for The Wonderful World. I hope it will be useful to you.
The library is on the left side of door A under the capital, but you can't go through the wall. The way to get in is to find the hidden item on the upper left side of door A. The key to the side door of the library. With it, you can meet Priest Rulan for the first time. At the place, on the far left side of the library building map, enter the developer easter egg, and then your royal capital can be 100% explored. By the way, after Chapter 7 (probably), Priest Rulan's power can be triggered in the royal capital market. In the second plot, you can complete an achievement by going to the beach to find him later (this is not hidden).
After entering, remember to talk to the person with the coolest hair to get the achievement.
