“It’s just a leftover scrap. He said that when Tianti was under construction, thousands upon thousands of tons of this stuff was shot into space, and it was made into the guide rail there and then hung back down from orbit again.… Soon, space travel will be popularized. I’ve asked my son to hook me up with business in that area.”

“You want to go to space?” asked Zhang Yuanchao, surprised.

“It’s not such a big deal. I’ve heard there’s not even hypergravity when you go up. It’s just like taking a long-distance sleeper train,” Miao Fuquan said dismissively. In the many years he had been unable to operate his mines, his family had gone into decline. He had sold off his villa four years ago, leaving this as his only residence. Yang Jinwen, whose son worked on the space elevator project, had in a single bound become the wealthiest of the three, and this sometimes made old Miao jealous.

“I’m not going to space,” Yang Jinwen said, looking up, and when he saw that Weiming had taken the boy to another room, he went on. “But my remains will. Hey, you two fellows don’t have any taboos about talking about this, do you?”

“What’s taboo about it? Still, why do you want to put your remains up there?” Zhang Yuanchao asked.

“You know there’s an electromagnetic launcher at the end of Tianti. When it’s time, my casket will be fired off at the third cosmic velocity and will fly out of the Solar System. It’s called a cosmic burial, you know. After I die, I don’t want to stay on an alien-occupied Earth. It’s a form of Escapism, I guess.”

“And if the aliens are defeated?”

“That’s practically impossible. Still, if it really happens, it’s no great loss. I get to roam the universe!”

Zhang Yuanchao shook his head. “You intellectuals with your weird ideas. They’re pointless. The fallen leaf returns to the root. I’m going to be buried in the yellow soil of the Earth.”

“Aren’t you afraid that the Trisolarans will dig up your grave?”

At this, Miao Fuquan, who had been silent, suddenly grew excited. He motioned for the others to draw closer, and lowered his voice, as if afraid that the sophons would hear: “Don’t tell anyone, but I’ve thought of something. I have lots of empty mines in Shanxi.…”

“You want to be buried there?”

“No, no. They’re all small pit mines. How deep can they be? But in several places they’re connected to major state-owned mines, and by following their abandoned works, you can get all the way down to four hundred meters below ground. Is that deep enough for you? Then we blast the shaft wall. I don’t think the Trisolarans will be able to dig down there.”
