At the command center, everyone including the grand duke was stunned when they heard what the crown princess had just said, especially the part about the mutated Zerg Prince coming off him. This meant that this invasion happening at this time was all because the Zerg Prince had found Ye Caoyun was here and came here all for him. They all knew that the Zerg Race can increase their power and aid their evolution through eating something filled with energy.
This is also the reason why they eat humans. For them humans, especially awakened ones, were their greatest nourishment. That's why most sentinel and guides who were lost in the battlefield were never found. They were either eaten by the zerg race or they were lost forever within the endless space. So when the crown princess said that this mutated Zerg Prince came for him, no one was surprised.
