Zheng Daoxing did not knock. He pushed open the door and hurriedly walked in.
Galostan, who was frowning at a map on the table in the room, heard the voice and looked up at him. He frowned and asked, "How is it?"
Zheng Daoxing shook his head and said in a low voice, "I still can't contact them. I've asked the other students, but there's no news from them."
Galostan's frown deepened. After thinking in silence for a moment, he slapped the table with a muffled bang.
"Find them! We must find them!"
Zheng Daoxing smiled bitterly, "Find? How can we find it? This is not the Earth Federation. This lousy planet is not even covered by the Milky Way Network. If we go to the wilderness, it's impossible to find them without clues."
