The fleet shouldn't have any trouble locating others farther out. Call Gohn and Ander and have them do a search on grid from systems within range that have no planets if they don't find anything still in the systems and talk to Thing about it. Maybe it considered this already and has a reason for what it projected. It usually has ten steps figured beyond what we thought of." "Thing won't be able to respond for awhile. Maita and T Six are working on various things while Thing and Z are handling their own problems. We got them en route before. Maita doesn't have any idea of how long they'll be busy. "From what I can tell, the brain seems to be holed up in a cave or something. It's built a couple of robots or servos and is doing something inside there." "It isn't mining or anything?" "It's not doing much of anything, judging by the energy use. It's barely detectable ... so!" "Yes. It was somehow damaged. The reactors were destroyed and its generation power is poor, so it has to build something first to recharge itself. It's using only the servos that were aboard from the first – those it brought with it. "This is one we shouldn't have a lot of problems with. Maybe I can get to it to read it." "It's been here for twenty or twenty five years. The damage must be pretty serious. Its ability to produce the robots and servos is gone." "And it doesn't have energy to spare for weapons. Maybe we've found the one I can read at last! It'll save us a lot of time if I can. "We've accounted for five, and we know there were a minimum of fourteen. Of the other nine, the fleet got rid of one, leaving a minimum of eight more. "One is on Killit almost certainly. Seven. "I'm getting a worse and worse feeling about Killit. With that population in the stage they're in we could have a very hard brain to get rid of. I don't like the way that thing always starts building nuclears. It's too much like the Immins for my tastes!" "Hold on," TR said, and I waited a few minutes. "Okay. Ander reports his fleet destroyed four and lost one ship through a very stupid mistake. We told them this thing is known for trickery, yet the ship approached what they thought was a dead brain ship and were destroyed. Twelve crewmembers. "Two other ships were dispatched and slagged the brain there. There are three more at minimum." I went aground and found the sealed entrance to the cave. A floater found another entrance big enough to get through over a flowing stream coming from inside of the mountain, so I went in to confront the brain. My problem was to prevent it from self-destructing and taking me with it, though its fusion generator wasn't working much at all. There was some high radiation in the cave, but I'm a machine, so it would have no effect on me. The brain ship was in a cavern. It had a large rupture on one side and had three servos working around an old-style electrical generator that worked on a flowing water principle in a stream flowing from the cavern out along the mountain where I came in. It was an easy thing to enter the ship through the hole, which was directly into the machinery storage area, and then into the generator area. There would be much too much leakage of current in some of these points for the brain to advance very rapidly from the waterwheel, but it would soon be able to direct servos to repair those lines. Once it had that power it could slowly build its strength until it could begin mining. There was iron in this cave, so it could then expand rapidly. Less than a hundred years from now it could build another fusion reactor. I went through a narrow passage and into various rooms. The beam weapons were usable but unpowered, as were the rest of the defenses. The nuclears weren't usable because they must be launched. There was some activity around some of those missiles, so I checked it out. It was building a plutonium reactor with the materials from the missiles! It would be unshielded and dangerous, but would work. This
