The Swirl Domain had already become a veritable battlefield.
Perhaps due to an unfair distribution of benefits or some other problem, Supremacy Qiandi and Supremacy Muzhou parted ways, and even turned against each other. In the end, Supremacy Qiandi and Supremacy Muzhou each called some friends, and tried to occupy the new chiliocosm domain in the Swirl Domain.
Hence, the Swirl Domain was already famous. Many Controllers had entered the Swirl Domain to "explore". The entire Swirl Domain had already become a battlefield for countless Controller factions, large and small.
Although there were no Celestial Devils, the competition between Controllers was still very intense. Many Controller Supremacies had already fallen. Even many Controllers with hundreds of worlds had fallen.
For the sake of benefits, there was actually not much difference between Controllers and Celestial Devils.
