In the Sam's park, the shopping zone is the first thing and it was in a most unique shops they have seen, but that was not the most unique and surprising thing that was awaiting the customers.
The next zone is a circular zone which surrounded the food zone.
The circular zone is full of challenges hence named challenge zone.
This is where the inscription tower and the formation tower.
There are many challenges in this place which would test many of the qualities and abilities of the cultivator.
This is an amusement park for the cultivators, instead of rides and games, here Sam combined the fun and tests to make money off of it.
Some of these challenges are completely under the formation tower and inscription tower. It was test for the knowledge of a cultivator on the formations and inscriptions and their ability to decrypt the formations and inscriptions.
