At the end of the first lap, the rightmost torch was still lit, and the rest of the torches went out. Go back counterclockwise at this time. The location is the second door on the right. You need to complete today's world mission to get the feather. First, we can see a Thunderbird in the picture below. After using feathers, a torch will appear. According to the mural below, an organ will appear after using feathers. There are two one-eyed babies and a relic crane. After the defeat, you can see the precious treasure chest and open the door to decrypt it after going out.
