“I don’t know anything about space warfare, of course, but if you want to compare it to a wooden boat versus a carrier, then I think it’s just a matter of having the courage to act and the confidence in a victory. A wooden boat could carry a small squad of divers who’ll wait in the carrier’s path. When the enemy draws near, they’ll dive in and the boat will leave. Then when the carrier comes close, they’ll attach a bomb to the bottom of the hull and sink the carrier.… Of course this would be exceedingly difficult, but it’s not impossible.”

Wu Yue nodded. “Not bad. People have tried it before. In the Second World War, the British did that as part of the effort to sink the Tirpitz, only they used a minisub. In the 1980s, during the Malvinas War, a few Argentine special forces soldiers took Italian limpet mines into Spain and attempted to blow up a British warship docked in the harbor at Gibraltar. You know what happened to them.”

“But what we have is not just a small wooden boat. A one- or two-thousand-ton nuclear bomb can be made small enough for one or two divers to take underwater, and when it’s attached to the underside of a carrier, it won’t just sink it, it’ll blow the whole carrier to smithereens.”

“Sometimes you’ve got a fantastic imagination,” Wu Yue said with a smile.

“I’ve got confidence in our victory.” Zhang Beihai looked out at Tang, the distant shower of welding sparks reflected in his pupils like two small flames.

Wu Yue too looked out at Tang, and a new vision took hold of him: The ship was no longer a ruined ancient fortress but a prehistoric cliff with a multitude of deep caves carved into it, and the scattered sparks were flickering firelight in those caves.

After takeoff and all through dinner, Luo Ji refrained from asking Shi Qiang anything about where they were headed, or what exactly had happened, reasoning that if Shi Qiang was going to tell him anything, he would already have come out with it. Once, he unbuckled his seat belt and got up to look out the cabin window, even though he knew he would see nothing through the darkness, but Shi Qiang followed him and pulled down the window shade, saying that there was nothing to see out there.

“Why don’t we chat for a while longer, and then go to sleep. What do you say?” asked Shi Qiang as he drew out a cigarette, then quickly put it back, remembering he was on a plane.

“Sleep? So this is a long flight?”

“Who cares? It’s a plane with beds. I say we take advantage of them.”

“You’re only responsible for taking me to my destination, right?”
