Landreth nodded. Even that was an effort for him now. He seemed suffering untold tortures. Supporting Landreth between them, they neared a low-structured building which he indicated. But Landreth fell. He was a dead weight in their grasp, then he crumpled to the ground. "The spaceship--wait until--" He tried to say more, but the words came slurred and unnatural. They left Landreth there, hurried on to the building he had pointed out. They pushed into a large shadowy room. It seemed a storeroom for tools, as well as strange machines similar to those in the smashed _Energon_ spacer. "Here they are!" Rikert spied the weapons, apparently the same ones Frane had taken from them. These _Energon_-controlled men were so contemptuous of Earth weapons that these had been tossed aside! "What next? Try and get to that spacer?" "Too many men about! We'll have to wait." Curt felt that was what Landreth had tried to tell him. Rikert grumbled; with an electro in his hand he felt he could overcome any obstacle. Remembering Lorine and the others, Curt thrust three electros in his belt and cradled the lensed radiant-gun. They hurried from the room. * * * * * Landreth was dead. But now, with a feeling of danger, Curt suddenly straightened away from the body. It glowed, as if from a weird inner aura! The aura seemed to coalesce, take definite form. An _Energon_ emerged directly upward from the earthly remains! Spinning, crackling angrily, it hung poised for a mere instant then darted straight at the two men. With an oath, Rikert swung his electro up and sent a charge at the six-inch globe. It connected, sent the thing buffeting back--but that was all. It swept beneath the beam and darted upon Rikert. It fastened just below his throat. Rikert screamed, clutched at the vibrant shape, but his fingers seemed to sink through it. Then the _Energon_ was gone--had completely entered his body! The event was so swift that Curt stood numbed with horror. To fire would have meant hitting Rikert. Now Curt saw the man stiffen, saw the startled expression leave his eyes. A queer emotion rippled across Rikert's features ... then he whirled upon Curt, the electro uplifted. "Rikert, you fool!" Curt's cry was instinctive as he flung himself aside. The electro-beam passed so close to his face he could feel the swirling heat of it. "Rikert--" But Rikert was no longer Earthian, he was _Energon_! The thought stabbed at Curt even as he brought the radiant beam around in a swift arc. It slashed across Rikert's body. A sickness rose within Curt, but it was his life or Rikert's now! He held the beam fast, saw Rikert go down in a mass of disintegrant flame. In seconds it was all over. Curt waited tensely, but this time there was no sign of the _Energon_ form. Could the radiant beam have destroyed it too? But here was no time for speculation. Through the deepening gloom he saw a group of men approaching. If they'd seen the flash of the gun--
