The warships of the Iridium Star United Empire Universe Army, with their powerful combat capabilities, largely rely on the assistance of robust warship AI. The Empire had achieved considerable heights in artificial intelligence technology and had categorized artificial intelligence into different classes. The ordinary civilian AIs are generally Class D artificial intelligence, which are far beyond what's on Earth, like Siri or AlphaDog. Class D artificial intelligence can smoothly respond to users' various needs and fathom the psychological state of its users. Xiao AI, serving Bai Zhongqi, is an example of a Class D life-type robot. However, Class D artificial intelligence does not have an emotional module, so they can react to human emotions but do not truly understand or genuinely generate personal emotions.
