"Leave the bomb there and withdraw," Kerk ordered. "We've had enough losses already."
A different man stared out of the screen. The officer was dead. "Sorry, sir," he said, "but it will be just as easy to push ahead as back as long as the gas grenades hold out. We're too close now to pull back."
"That's an order," Kerk shouted, but the man was gone from the screen and the advance continued.
Jason's fingers hurt where he had them clamped to the chair arm. He pulled them loose and massaged them. On the screen the black and white cave flowed steadily towards them. Minute after minute went by this way. Each time the animals attacked again, a few more gas grenades were used up.
"Something ahead—looks different," the panting voice cracked from the speaker. The narrow cave slowly opened out into a gigantic chamber, so large the roof and far walls were lost in the distance.
"What are those?" Kerk asked. "Get a searchlight over to the right there."
The picture on the screen was fuzzy and hard to see now, dimmed by the layers of rock in-between. Details couldn't be made out clearly, but it was obvious this was something unusual.
"Never saw ... anything quite like them before," the speaker said. "Look like big plants of some kind, ten meters tall at least—yet they're moving. Those branches, tentacles or whatever they are, keep pointing towards us and I get the darkest feeling in my head ..."
"Blast one, see what happens," Kerk said.
The gun fired and at the same instant an intensified wave of mental hatred rolled over the men, dropping them to the ground. They rolled in pain, blacked out and unable to think or fight the underground beasts that poured over them in renewed attack.
