In the game, The Orangutan in the Lost City requires players to get a specific disc as a clue to find other treasures. Now let me tell you the location of this disc. I hope this can be helpful to you.
1. The specific location is at the guard window sill in the mail room.
2. When you click, there will be a dialogue telling you that it is on the platform, but you cannot get it.
3. Then go to the warehouse on the upper left and click on the fire protection facilities on the upper right. You will be prompted to use a match to lead away, but you must find another way to avoid people who come to check.
4. Then go to the messy warehouse on the left side of the room below to push boxes.
If you can't find the CD the orangutan wants, you can go to the corresponding location in the game and look for it after reading the specific locations explained in the article.
