He watched by electron telescope. Like tiny insects, the fleet of Ades flashed over the surface of the planet. They seemed to have no purpose. They seemed to accomplish nothing. They darted here and there and fled for open space again, without ever touching more than the outermost reaches of the planet's atmosphere.

But it took time. They were just beginning to stream up into emptiness again when the first of the giant warships flashed back into view. This time it was ready for action.

Its beam-projectors flared thin streams of ions that were visible even in empty space. The ships of Ades plunged for it in masses. The fighting-beams flared terribly.

And the little ships vanished. Diving for it, plunging for it, raging toward it with every appearance of deadly assault, they flicked into transmitter-drive when the deadly beams touched them. Because the crews of every one were fitted with the wristlets and the relays which flung them into infinite speed when the fighting-beams struck.

In seconds, when the second and third and fourth Sinabian warships came back from the void prepared for battle, they found all of space about their home planet empty. They ragingly reported their encounter to headquarters.

Headquarters did not reply. The big ships went recklessly, alarmedly, down to ground to see what had happened. They feared annihilation had struck Sinab Two.

But it hadn't. The fleet of Ades had bombed the enemy planet, to be sure, but in a quite unprecedented fashion. They had simply dropped small round cases containing apparatus which was very easily made and to which not even the most conscientious of the exiles on Ades could object.

They were tiny broadcasting units, very much like one Kim had put in a decoy ship, which gave off the neuronic frequencies of the disciplinary circuit, tuned to men. The cases were seamless spheres, made of an alloy that could only be formed by powder metallurgy, and could not be melted or pierced at all.

It was the hardest substance developed in thirty thousand years of civilization. And at least one of those cases had been dropped on every large city of Sinab Two, and when they struck they began to broadcast.
