In the alternate dimension, after facing Xu Yuan's powerful form, the White Dragon Saint was scared.
The White Dragon Saint was powerful too. If the Dark Demon Dragon had signed a contract with a human Overlord, his strength would be severely limited because of the human. The White Dragon Saint knew that it was impossible for the Dark Demon Dragon to reach the peak of his power.
However, the Dark Demon Dragon was on top of the food chain of the Dragon Clan. The White Dragon Saint didn't want to offend such a powerful creature. In a battle, if the whole dragon clan could even match 10% of the Dark Demon Dragon, it was considered impressive.
The White Dragon Saint could only make one decision, and that was to surrender.
"Misunderstanding?" said Xu Yuan. "That's a pity because I can't take back the spell that has been cast. Either you die, or I die here. Only then will the magic be dispelled."
