The spaceship entered the asteroid belt, surrounded by rocks of various sizes. Nova gripped the controls tightly, carefully navigating through the dangers. Suddenly, a massive asteroid rushed from the side. Nova reacted quickly, and the ship grazed past the asteroid's edge. Photon quickly calculated the optimal route: "There's a safe passage three hundred kilometers ahead, but we need to accelerate." Nova gritted his teeth and pushed forward at full speed. After a thrilling few minutes, they finally crossed the asteroid belt, and a mysterious planet appeared ahead.
The spaceship landed on the surface of the unknown planet. The sky here had a strange purple hue, and the ground was covered with glowing crystals. Nova put on his spacesuit and carefully stepped out of the ship. He discovered ancient architectural ruins on this planet, seemingly left by some advanced civilization. Photon scanned the surroundings: "The energy readings on this planet are unusually high. Those crystals appear to be some kind of energy source." Nova walked toward a massive stone gate with complex symbols carved on it, seemingly telling an ancient story.
