"Devouring the Spirit of the World" had mentioned it featured in-app purchases when introduced, but Ren Suo had played for a long time without finding any. He had assumed the so-called 'in-app purchases' were just the initial creature selection screen.
Unexpectedly, like "Jedi Priest," "Devouring the Spirit of the World" would suddenly reveal its in-app purchases only after certain game metrics were met.
These days, rookies don't have the privilege of spending real money on games.
In "Jedi Priest," for example, you had to clear the first level before you could meet the Golden Ranger to gamble during rest time.
For "Devouring the Spirit of the World," however, it was only after obtaining an ace card that the Earth Spirit 'responsible for in-app purchases' would appear.
