Arena.

Shi Lang was touring the city with Crystal when he came to a place that was filled with echoes and cheers, a lot of people were walking around, some in groups and some alone. He could not help but ask the girl beside him, "What is this place?" 

Crystal said, "This is the arena, people from all generations come here to compete with each other and also settle death grudges. Every city on the planet has one such Arena, and is controlled by the Council." 

Shi Lang nodded and said, "This place can provide the outlet everyone needs to vent. I do not think that the younger generation is allowed to venture into the galaxy, right?" 

Crystal nodded and said, "Yes, some of the younger generation elites were sent out, but when they came in contact with pretentious people, the situation almost ended up in a war, thankfully the council intervened."
