Hidden Quest

For those who don't know how to complete the hidden quest to sell Golden Timber Block. First, proceed to Area 2. Upgrade Conveyor Machine 1 to the maximum → Unlock Machine 2 (Caution: Do not upgrade further after unlocking) → Obtain Golden Timber (This is my method, but I go to Area 3. Then, when I return to Area 2, logging becomes automatic, so I upgrade logging-related things. Once Golden Timber appears automatically, feed it into Machine 2) → Load the resulting timber onto the truck on the right and sell it. This completes the quest. If you have already upgraded your conveyor rank, you will have to start over. However, you can restart by deleting the app's storage.
