Ep 7. Saving the World from Ruins!

Ash and his friends arrive in the Sinnoh region, where they discover ancient ruins which they believe may hold valuable information about the region's history. However, they soon learn that an evil organization known as Team Galactic is also interested in the ruins, and plans to use their power to take over the world.

Determined to stop Team Galactic, Ash and his friends team up with a group of archaeologists and set out to explore the ruins in search of clues. Along the way, they encounter a group of wild Pokemon that have been affected by Team Galactic's experiments and must battle them in order to save them.

As they delve deeper into the ruins, Ash and his friends discover a hidden chamber that contains a powerful artifact which could be the key to stopping Team Galactic's plans. But in order to retrieve the artifact, they must first solve a series of complex puzzles and defeat a group of Team Galactic's most powerful Pokemon trainers.

After a challenging battle, Ash and his friends are able to retrieve the artifact and use it to shut down Team Galactic's operations in the region. They are hailed as heroes by the people of Sinnoh and continue on their journey, ready to face whatever challenges lie ahead.
