  20. AN INVITATION FROM THE PUBLISHER

“Far from it! Off by a factor of 1092! Besides, how can one atom store a whole poem? The memory devices of human bug-bugs would have needed more atoms to store one poem than your population. As for us, ai, technology to store one bit per atom is still in the laboratory stage….”

“Here you display your shortsightedness and lack of imagination, Emissary, one of the reasons behind the laggardly advancement of Devouring Empire technology,” Li Bai said, laughing. “Using quantum storage devices based on the quantum superposition principle, the poems can be stored in very little matter. Of course, quantum storage is none too stable. To preserve the poems forever, it needs to be used in tandem with more traditional storage techniques. Nonetheless, the amount of matter required is minuscule.”

“How much?” Bigtooth asked, looking as if his heart were in his throat.

“Approximately 1057 atoms, a pittance really.”

“That’s … that’s exactly the amount of matter in the solar system!”

“Correct, including all the planets orbiting the sun, and of course including the Devouring Empire.”

Li Bai said this last sentence easily and naturally, but it struck Yi Yi like a bolt out of the blue. Bigtooth, on the other hand, seemed to have calmed down. After the long torment of sensing disaster on the horizon, the actual onslaught only left a sense of relief.

“Can’t you convert pure energy into matter?” asked Bigtooth.

“You should know how much energy it would take to create such an enormous amount of matter. The prospect is unimaginable even to us. We’ll go with ready-made.”

“His Majesty’s concerns weren’t unjustified,” Bigtooth murmured to himself.

“Yes, yes,” Li Bai said happily. “I informed the Emperor of the Devourers the day before yesterday. This great ring-world empire shall be used for an even greater goal. The dinosaurs should feel honored.”

“Esteemed god, you’ll see how the Devouring Empire feels,” Bigtooth said darkly. “I also have one more concern. Compared to the sun, the amount of matter in the Devouring Empire is insignificantly minuscule. Is it really necessary to destroy a civilization millions of years of evolution in the making, just to obtain a few scraps?”

“I fully understand your reservations. But you must know, extinguishing, cooling, and disassembling the sun will take a long time. The quantum calculations should begin before then, and we need to save the resulting poems elsewhere so that the computer can clear its internal storage and continue work. Therefore the planets and the Devouring Empire, which can immediately provide matter for manufacturing storage devices, are crucial.”
