The Outworld fiends had retreated. They had no choice. If they didn't retreat, they would be annihilated. They had to retreat. They had an Army behind them that could provide support. They didn't have to fight to the death with Zhao Hai.
In reality, none of the other realm demons were willing to fight Zhao Hai to the death. They knew Zhao Hai's strength all too well. As soon as the other realm demons heard Zhao Hai's name, they were already scared even before the battle started.
Zhe ruhai and the others stood at the back, watching the battle in a daze. This battle had ended in a way they had never imagined. They were unable to react in time.
