Nova rushed back to the sealing ground with the energy core, but dark forces had already broken through part of the seal. Elder Galaxy was struggling to suppress the dark energy. Nova quickly placed the energy core into the sealing device, and a dazzling light flashed as the seal was reinforced. But the planet began to shake violently, and the entire underground city was collapsing. Elder Galaxy said: "Go! The planet is about to be destroyed. You must leave!" Nova took one last look at Elder Galaxy and ran toward the spaceship. At the last moment, the ship broke through the planet's surface.
Nova returned to the space station and reported the adventure to the commander. Although the planet was destroyed, the dark forces were resealed, and the galaxy was temporarily safe. Nova stood before the observation window, looking at the starry sky where the mysterious planet once existed. Photon floated over: "Nova, Elder Galaxy transmitted a message to me at the last moment." Nova opened the message, and Elder Galaxy's voice resonated: "Young one, you have become a true Star Guardian. There are many places in the universe that need protection. Your mission has just begun." Nova smiled, knowing this was only the beginning of his adventures.
