After around 20 minutes, Duke Whirlwind appeared in front of the academy. During the day, there were no guards in front of the gates since there were plenty of powerful teachers walking around. They would notice if someone entered that shouldn't have entered.
Shang looked out of a window of George's office and looked at the packed training grounds. Shang couldn't help remembering the time when he had been one of those students.
Duke Whirlwind walked alongside the road towards the main building, being greeted by several students and teachers.
He greeted them back with a smile and entered the building. Duke Whirlwind didn't need to ask where George and Shang were currently. After all, he had a Spirit Sense.
After getting to the fifth floor, Duke Whirlwind entered the office without knocking. Why would he? The two occupants already knew that he was there.
