Pergilah ke One Island. Pergilah ke jalan masuk  Mt. Lanjutkan terus ke bawah sampai level dasar. Ambil Ruby dan keluar.

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
You will need a Pokémon who knows Surf to do this.  Speak to Celio and he will explain that you need to find an item for his machine. Ember. On the lower right side of the area, you will see some Team Rocket members. You will hear the first password to the Rocket Warehouse. Battle them, and enter the cave. You do not need to read any of the braille charts. You will need a Pokémon with Strength to get through the cave. You can either use an escape rope, use "Dig" or exit the way you came in.
