Looking at the magic sphere in front of him, emitting noises like a little girl's chatter, Cheng Ziang couldn't help but think of a term - artificial intelligence. Of course, the intelligence of these little girls in front of him was too poor to bear the term intelligence, but they were quite similar to an advanced concept on Earth.
In the Halo series of video games, the Master Chief risks his life with an artificial intelligence. The AI he carries is presented in a way quite similar to these magic spheres. The Advance Team members fight with these magic spheres, just like how the Master Chief fights with his artificial intelligence, the two situations share an astonishing similarity.
Cheng Ziang even had such an idea; utilizing the high mobility and stealth of the Ghosts, they could easily scout ahead for the Advance Team and establish connections with various combat units.
