The expedition ended. Leo stood on the base observation deck, looking at the beautiful scenery. Cosmo and the Ice Spirit appeared together and solemnly said, "Leo, you have been chosen as an Exploration Guardian. Your mission is to protect the natural environment and carry forward the spirit of exploration." Leo raised his right hand and made a solemn oath: "I promise to guard nature, protect the environment, and ensure the journey of exploration continues forever." Professor Nova smiled with pride.
