"Interceptor?" Boateng shook his head. "Never heard or seen one before. Is it a large warship?"
Xia Fei looked slightly disappointed. "No, it's about the same size as a frigate but has a 14,000m/s cruise speed. I'm guessing that this isn't its limit; its top speed can probably break past the 20,000m/s threshold."
"My goodness!" Boateng was at a loss for words; evidently, he could barely believe the 20,000m/s that Xia Fei estimated. "There existed high-performance proton engines before the advent of warp engines. Although those engines allowed for incredibly high speeds, they were largely unstable, requiring plenty of fuel, and were troublesome to maintain. Nobody uses those anymore."
Xia Fei searched through his memory before shaking his head. "From what I've observed, the ship doesn't have a proton engine. Whatever. Since we can't figure it out, we'll just let it be."
