Head to Cianwood City After defeating Pryce, the next stop on your journey is Cianwood City. To get there, simply follow the path northeast out of Mahogany Town. As you make your way to Cianwood City, you'll encounter some new opponents including trainers using Fighting-type Pokemon and Team Rocket grunts.

At Cianwood City, challenge Jasmine from inside the Gym of Cianwood City which would grant you another badge from this city; Zephyr Badge.
