All he’s doing is hooking together all of those and modifying them a bit to work in parallel, but it will apparently make a small supercomputer.”

“As long as it helps create the lance, anything is fine,” said Othinus as if spitting out the words. “Will Bersi also handle this…whatever this thing in the cooler is. Academy City’s #2? Anyway, will he handle Fräulein Kreutune’s substitute?”

His job was to find the computers from the radios, fishfinders, navigation control systems, and other devices installed on the dozens or even hundreds of ruined ships that had drifted to Sargasso. Once he found them, he would connect them with cables and make some programming adjustments so they could function as a parallel processor. This high-speed and large-scale processor was necessary to use the empty husk of the #2 which had been retrieved from Academy City.
