A huge black wreckage lay ahead, and the lush, glowing deep-sea plants surrounding it revealed the details of the wreckage. It was about 10-km long and it had a slender body as well as a large number of crystalline sheet metal distributed around it. The crystalline sheets of metal were of different sizes, ranging from about dozens of meters to even hundreds of meters wide. They were spread like petals or sails along the axis of the wreckage and in all directions. On the back of the wreckage, there were some strange metallic structures, which had swelled up. Something like radiator grids were arranged neatly on it.
