Near and far, innumerable similar crystalline worlds hung in the black sky. Some of them still rotated about their own axes. The surrounding rotating and nonrotating blocks of ice reflected and refracted the sunlight. On the ice the three astronauts stood on, they cast a dazzling pattern of ever-changing light and shadow. In the distance, the blocks of ice in the ring looked smaller and smaller, but gathered closer and closer together, gradually shrinking into a delicate, silver belt twisting toward the other side of the Earth. The closest block of ice was only three thousand meters away from this one. Because it rotated about its minor axis, in their eyes, such a rotation had a breathtaking momentum, as though they were three tiny ants watching a crystalline skyscraper collapsing over and over again. Due to gravity, these two ice blocks would eventually crash into each other. The light-filtering membranes would rupture and the blocks of ice would disintegrate. The smashed blocks of ice would quickly evaporate in the sunlight and disappear. Such collisions had already happened twice in the ring of ice. This was also why this block was the first block of ice to be forced back.

First, an astronaut started the driller vehicle. As the drill head spun, crumbs of ice flew out in a cone-shaped spray, twinkling in the sunlight. The driller vehicle broke through the invisible light-filtering membrane. Like a twisting screw, it dug into the ice, leaving a round hole in its wake. Along with the hole that stretched into the depths of the ice, a faint white line could be seen in the ice itself. Once the hole reached the prescribed depth, the vehicle headed out toward another part of the ice. It then bored another hole. At last, it drilled four holes in total. They all intersected at one point deep in the ice.

The astronauts inserted the three waveguides into three of the holes, then inserted the expeller into the wider fourth hole. The expeller tube’s mouth was pointed in the direction of the motion of the block of ice. After that, the astronauts used a thin tube to caulk the gap the three waveguides and the expeller tube left against their holes’ walls with a fast-sealing liquid to create a good seal. Finally, they opened the parabolic reflectors. If the initial phase of ocean reclamation employed the latest technology, it was these parabolic reflectors. They were a miracle created by nanotechnology. Folded up, each was only a cubic meter. Unfolded, each formed a giant reflector five hundred meters in diameter. These three reflectors were like three silver lotus leaves that grew on the block of ice. The astronauts adjusted each waveguide so that its receiver coincided with the focal point of its reflector.
