Pearl was in the second Arena, one floor above the other one. He sat in one of the seats, waiting for his turn.

Since there were 8 arenas in total, they were separated in weird ways.

Fighters in the Immortal Ascendant realm were made to fight in the first arena. In the 2nd arena, those with a cultivation base lower than Immortal Origin 5th realm fought. The rest of those in the same realm fought on the 3rd floor.

The 4th and 5th arenas were for people in the early and late Immortal Transcendent realm. Then, the 6th and 7th floors were for people in the early and late Immortal Spirit realm.

Finally, the 8th floor's Arena was for anyone who made it past the other arenas, so technically anyone could fight there, but it was almost always just people from the 7th arena who beat others that got to fight there.

From what Pearl had heard, these fights were set in advance, and people came specifically for them.
