* Receive the Psychic Badge: This is your sixth badge, signifying you've conquered the gym and are one step closer to becoming the Pokémon League Champion.
* Learn TM42 (Facade): Sabrina will give you the TM for Facade, a Normal-type move that can be very useful against Psychic-type Pokémon.
* Continue your journey: With the Psychic Badge, you can now travel through the Victory Road to reach the Pokémon League. However, you may want to train your team further before heading to the League.
* Explore Saffron City: Saffron City is a hub for various activities, including:
* Visiting the Silph Co.: This building is a major part of the game's storyline, so it's worth exploring.
* Exploring the Game Corner: The Game Corner offers a chance to win rare items and Pokémon, though it's a gamble.
* Visit the Department Store: This store has a wide selection of items you might need.
Remember that the Silph Co. is a crucial part of the story, and you'll need to complete a specific mission there. The Game Corner and Department Store are optional, but can be beneficial if you want to stock up on items or Pokémon.
Ultimately, what you do after beating Sabrina depends on your goals in the game. You can choose to focus on training your team, explore Saffron City, or head directly to the Pokémon League.
