The Bloody Space River was actually forbidden grounds for many martialists. This was because there were countless dangerous beasts and disasters in this region. Most importantly, this was a killing ground for the four different factions.
However, thanks to the blossoming Blood Jade Flower, the four factions had lifted the prohibition on entering the Bloody Space River.
The martialists from the four different factions were not supposed to fight before the upcoming battle took place.
Of course, being able to spectate the battle came with rules as well. Should anyone not follow the given set of rules while spectating the match, they would immediately be expelled on the spot.
The total number of rules one had to follow to prevent getting expelled was over 30. However, even so, there were still many spectators who came from all directions just to watch.
