Update 1.49 added another Wonderful Journey to AFK Arena, called the Kingdom of Denial and timed to coincide with Halloween. In it you have to guide the ghost across the entire map to his "house", solving a puzzle along the way.

Step 1
Follow the path until you find the first candy pumpkin. Then destroy all the camps in your path and collect relics.
If you fill the pumpkin with candy, the Ghost will appear, looking for sweets.
Step 2
Now take the path to the left where you will find a candy pumpkin and a zombie tile that blocks the path.
Slide the pumpkin to the right and then fill it to lure the ghost to stand on the rock and turn off the zombie tile blocking the path. Clear the enemy camps and get the Golden Chests.
Step 3
Follow the open path, then destroy the camp and take two Golden Chests. Then move the cart up to open the way to the next section of the map.
Step 4
You will be taken to the mercenary camp, where you can get one of two heroes for support: Ainz or Albedo. If you don't take one of them, you won't be able to take the Crystal Chest!
The resulting hero will be needed in the battle in the camp on the left, destroying which, you will receive the first Crystal Chest. It contains 10 summoning scrolls.
Step 5
Then you need to force the ghost to stand on the rock again to deactivate the next zombie tile. To do this, first use the lamp in the middle.
Then move the pumpkin cart up, then fill the pumpkin to summon the ghost. If you don't light the lamp first, the ghost will not stand on the rock and you will need to lure it back and repeat the process.
Now move the cart to the left to get to the next section of the map
Step 6
Use the red lever to lower the red stone next to the pumpkin.
Then activate the lamp BEFORE filling the pumpkin you see in the screenshot to summon the ghost. Your goal here is to get the ghost to stand on the red stone so you can raise it to the top level.
Step 7
Now go left and use the red lever again. The ghost should be at the top level.
Then go left and place the pumpkin on the blue stone, then use the blue lever, which will lure the ghost to the pumpkin.
Go to the right, where there is another pumpkin on the first floor - interact with it.
Then use the blue lever again. This will cause the ghost to stand on the rock and deactivate the zombie tile that is blocking the path to the lamp.
Step 8
Use the lamp on the red stone to light it. This is the last thing to do to bring the ghost to its final location.
After turning on the lamp, use the red lever to get to the upper level.
Then use the pumpkin on the left side again on the blue stone and use the blue lever to pick it up. Since the lamp is on, the ghost will now reach the end and enter his house. This will open the way to the second Crystal Chest.
Make sure you destroy all the camps on the map and collect all the relics - they will help you in the final battles.
