The points arena here is much larger than the free arena over there, divided into several platforms, and there are more spectators. Outside the arena, quite a few bets are placed.
The levels of the arenas progress incrementally, with stronger opponents as you move up. However, which level of the arena one can fight in isn't a choice one can make; it's determined by points.
The higher the points, the higher the level of the arena; conversely, the lower the points, the lower the level of the arena one has to go to.
Points are mainly earned through combat; winning a match in the arena nets you a certain number of points. The higher you go, the more points you win, and naturally, the more you would lose if you were defeated.
For newcomers like Qu Tong, with a starting score of zero, the only option is to start from the lowest-level arena and fight your way up step by step.
