But before them, the small torpedo still floated, held now on its own power! From it came waves of thought, the waves that man and machine alike could understand. "F-1 has destroyed his generators. They can be repaired; his rhythm can be re-established. It is not worth it, my type is better. F-1 has done his work. See." From the floating machine there broke a stream of brilliant light that floated like some cloud of luminescence down a straight channel. It flooded F-1, and as it touched it, F-1 seemed to flow into it, and float back along it, in atomic sections. In seconds the mass of metal was gone. "It is impossible to use that more rapidly, however, lest the matter disintegrate instantly to energy. The Ultimate Energy which is in me is generated. F-1 has done its work, and the memory-stacks that he has put in me are electronic, not atomic, as they are in you, nor molecular as in man. The capacity of mine are unlimited. Already they hold all memories of all the things each of you has done, known and seen. I shall make others of my type." Again that weird process began, but now there were no flashing tentacles. There was only the weird glow of forces that played with, and laughed at matter, and its futilely resisting electrons. Lurid flares of energy shot up, now and again they played over the fighting, mingling, dancing forces. Then suddenly the whine of transmuted air died, and again the forces strained. A small cylinder, smaller even than its creator, floated where the forces had danced. "The problem has been solved, F-2?" asked Roal. "It is done, Roal. The Ultimate Energy is at our disposal," replied F-2. "This, I have made, is not a scientist. It is a coordinator machine--a ruler." "F-2, only a part of the problem is solved. Half of half of the beams of Death are not yet stopped. And we have the attack system," said the ruler machine. Force played from it, and on its sides appeared C-R-U-1 in dully glowing golden light. "Some life-form, and we shall see," said F-2. Minutes later a life-form investigator came with a small cage, which held a guinea pig. Forces played about the base of F-2, and moments later, came a pale-green beam therefrom. It passed through the guinea pig, and the little animal fell dead. "At least, we have the beam. I can see no screen for this beam. I believe there is none. Let machines be made and attack that enemy life-form." Machines can do things much more quickly, and with fuller cooperation than man ever could. In a matter of hours, under the direction of C-R-U-1, they had built a great automatic machine on the clear bare surface of the rock. In hours more, thousands of the tiny, material-energy driven machines were floating up and out. * * *
