_Milky Way Academy, Library_
Elder Cao was sitting in front of the entrance of the library cross-legged. He was actually floating in the air, not touching the ground.
A few students could be seen entering and exiting the library. There were also two other deacons standing at the gate of the library, behaving like guards.
Suddenly, Elder Cao opened his eyes. Right now, he suddenly sensed an extremely familiar aura moving towards the library at a high speed. This aura was something that he had sensed two and half years ago.
Elder Cao frowned, tilted his head, and looked in his right direction. From there, he could see a young man flying towards him. This young man's speed was extremely fast, and it only took him a few seconds to arrive in front of him.
"Elder Cao!"
Qin Feng smiled, cupped his hand, and saluted.
Elder Cao didn't say anything for a while. Then he freed his legs and stand up on the ground. Then said, "Aren't you afraid I will kill you. Why did you come here?"
