After a while, the old man took off his glasses and walked toward Jack with his hands behind his back.
Little Digger, like an apprentice, followed the old man obediently.
"Young man, what are you doing here?"
Walking up to Jack, the old man looked at him up and down and asked.
Little Digger winked at Jack and warned him not to talk nonsense.
"Well, I don't want to do anything. I just want to take a walk."
Jack said calmly.
"We don't welcome outsiders here unless you are here for business."
The old man frowned.
"Business for what?"
"Of course, the business for shipbuilding."
"Shipbuilding? Spacecraft?"
Jack was surprised to hear that. Were the people on the moon so awesome? They could even make a spacecraft.
The old man frowned deeper. "You really come here without knowing anything!" Then he pointed to the left wall.
Jack looked in the direction of his finger.
On the wall hung various patterns of sea ships.
