Yu Su walked into the small house and saw a very wide counter with a white-haired old man lying on it.
The old man was the only one in the management office.
The old man picked up a black chess piece with his right hand and placed it on the chessboard.
He was playing chess with himself.
Without looking up, the old man said, "It's so late. What are you doing here?"
Yu Su replied, "I'm here to get something."
After saying that, Yu Su took out the jade pendant and key from her purse and placed the key on a machine that looked like a scanner.
The apparatus hummed and flashed with a colorful luster.
The old man raised his head and glanced at the jade pendant. He said, "The item is in the 156th room. Go into the sixth compartment and open the 12th cabinet. It's in compartment 9 of the cabinet. Take these two things and open it!"
Yu Su nodded. "Thank you!"
Then, she turned around and walked into the storage hall.
