Before Zhang Beihai entered hibernation, national space forces had begun conducting drills in the weightlessness of space. They had developed specifications and drill books as a result, but implementation had been particularly difficult. Personnel could use their space suits’ microthrusters to move about outside the cabin, but since they lacked propulsion equipment inside, they had to maneuver by pushing against bulkheads and paddling the air. Under such conditions, it was very difficult to form neat lines. Now, he was astonished at the sight of more than two thousand people floating in space in such a neat formation without any supports. These days, personnel moved through weightless cabins primarily by using magnetic belts, fabricated from superconductors and containing a circuit that generated a magnetic field that interacted with the magnetic field that was always present in the cabins and corridors of the spacecraft. With a tiny controller in hand, they could move freely inside the ship. Zhang Beihai was now putting on such a belt, but it would require skill to master.

He watched the formation of space soldiers, a generation that had grown up in the fleet. Their tall, slender bodies had none of the clumsy sturdiness of people growing up under Earth’s gravity, but possessed the light agility of spacers. Three officers were in front of the formation, and his gaze eventually rested on the young woman in the center with four glittering stars on her shoulder—Natural Selection’s captain, no doubt. A typical representative of new space humanity, taller even than Zhang Beihai, who was himself quite tall. She drifted easily over from the formation, her slender body floating through space like an elegant musical note. When she reached Zhang Beihai and the chief of staff she stopped, and the hair that had been floating behind her rippled around the fair skin of her neck. Her eyes were full of sunshine and vitality, and Zhang Beihai immediately trusted her, because the Imprinted would never wear such an expression.

“Dongfang Yanxu, captain of Natural Selection,” she said, saluting him. A note of playful challenge appeared in her eyes. “On behalf of the entire crew, I offer a gift to my forbear.” She extended her hand, and he saw that, although the object she held in it had changed quite a bit, it was still recognizably a pistol. “If you really find that I have defeatist thinking and Escapist goals, you may use this to kill me.”

Getting to the surface was easy. The trunk of every giant tree building was a pillar supporting the dome of the underground city, and from the trunk you could take an elevator directly to the surface, passing through more than three hundred meters of rock. When Luo Ji and Shi Qiang exited the elevator, they felt nostalgic, a feeling prompted by one thing: The walls and floor of the exit hall did not have activated display windows. Information was displayed on actual display screens that hung from the ceiling. It looked like an old subway station, and most of the handful of people in it wore clothes that didn’t flash.
