As soon as Ning reached the Tower, he immediately went to find Waxil, the head of this city's tower.

"Oh Terran, you're back," Waxil said. "I hope your 2 days off were useful."

"Yes, brother Waxil. You have no idea," Ning told him. "I have come to consult something with you, do you have some time?" 

"Uh, I'm free for the hour. What is it?" Waxil asked.

Ning took out a small bead of glass and placed it on the table in front of Waxil. The bead was about the size of 2 centimeters in diameter and was completely transparent.

Waxil looked at the glass bead for a few seconds with questions on his head. "What's this?" he asked.

"Just wait a minute, brother Waxil," Ning said and sat on the chair to wait for the minute to pass.

Waxil was curious as to what the genius of his tower was making him look at.

'Did he bring back a souvenir from wherever he went in the last 2 days?' he wondered.
