Duel.

Shi Lang and the rest of the team made their way to the arena. Behind the palace of change (The new name of the palace of sins) was a huge arena that could fit ten thousand people. Arcadia was the capital planet and after Cara took charge, she made the whole planet open for the citizen. 

There was no restriction but the citizens qualified to live here had to go through an interview. Only when they have cleared the interview will they get the identity card to live here. Today a computer system randomly selected people, and families and sent them the invitation to attend the duel. 

Shi Lang and the rest of the Terran team also had a great reputation in the palace and the world outside. During the past year, they have appeared on the broadcasts and at public events a lot many times.
