# Shop Purchase of Higher-Level Pets

For new players or those wishing to quickly obtain higher-level pets, the game store offers a one-time purchase option. This allows players to directly buy pets of any level, but each account is limited to one such purchase.

**Purchase Rules:**

* Each account can only make one purchase of a higher-level pet.
* Pet prices are based on their level and corresponding market value.

These three pathways for pet upgrading allow players to choose the most suitable upgrading method according to their strategy and game progress. This diversity of choices enhances the interactivity and strategic nature of the game, offering flexibility for players at different levels.
