As Earth's fleet in awesome array, advanced toward the asteroid's position which Cynthia had given, Aladdian kept a ceaseless vigil at the televise. In far off N'Vaarl, the palace grounds were a sea of upturned Venusian faces intent upon their screen. Dar Vaajo sat brooding on his barbaric throne on Mars, his craggy face dark with passion, thinking of the upstart Luhor who had wrecked his plans. Within the austere Council chamber of Earth, the Coordinator paced to and fro before the screen, while the awed Council didn't dare to stir. It hadn't been hard for the ethero-screens of each world to pick out the flaming majesty of Earth's fleet, and they had followed its progress for hours. The meteoric speed seemed a snail's pace, across the respective televise panels. "Look!" Aladdian cried, spilling the cup of hot concentrate Cynthia had brought to her. With electrifying suddenness, the scene in the panel had leaped to vivid life. Concentric whorls of green, disintegrating light flashed from all units of Earth's fleet simultaneously, merging into a single appalling cloud that preceded the fleet itself. To the watchers, the spread of the light seemed slow, but it must have encompassed thousands of miles. "But why?" Aladdian breathed, even as she twisted the dials trying to center the scene more perfectly. "They're not within hours of the asteroid belt, and they will only give their position away to Luhor!" Carston, Mark and the others had come crowding into the room to watch the scene. Carston whispered, exultantly, "That green light is radio-active disintegrating energy! It merges with whatever it touches, unbalancing the atomic structure of metal. Wait'll they envelop Luhor's asteroid in that!" "Yes, I know it well," Aladdian murmured. "They used it in the long war against Venus. But there is a neutralizing force now, which even Earth does not know. George Marnik developed it, right here on Vulcan Base." Carston's lips curled, but he said nothing. The sight of Earth's mighty armada sweeping forward on its mission had instilled him with a swaggering confidence. They continued to watch the scene in silence, even as the Earth Council and the people of Venus and Dar Vaajo on Mars were watching. Still the Fleet swept forward. Minutes passed. The greenish half-circle of light preceded it, beating back the darkness, expanding unimaginable distances as though reaching out greedy hands. Then suddenly Aladdian's words came true. * * * * * From a point in space far in advance of the Fleet, a tiny white beam of light became visible. It reached out like a slashing saber, swiftly expanding and closing the gap of darkness. It came from the asteroid itself, now revealed to the watchers for the first time--merely a tiny dark mass that seemed to move forward with infinite caution against the Fleet.
