Hello poster, the layers mentioned refer to certain layers of the "Magic Tower Cake" that must be cleared before the item can be purchased.

The ways to obtain prestige are:

1. Playing Magic Tower Cake (main channel).

2. Weekly Magic Tower Cake Ranking Rewards (Main Channel).

3. Some activities in the game (rarely appear).

4. Make a pious wish (500D each time), and there is a chance of making a prestige coin (coin value 100).

If you have any questions, please feel free to ask further questions. I hope you will accept them. Thank you!
