Xu Nian looked at Wan Feng in the distance, falling into deep thought.
He had just noticed a detail.
That was, Wan Feng's domain erupted at the moment his spear was released.
And not at the start of the battle, releasing the domain first.
As he retrieved the spear, the domain also withdrew.
"Instantly releasing and withdrawing a domain is a skill for advancing Law Manifestation, I'm also trying to grasp it now," Xue Bing said with a smile.
Evidently, he also perceived this point.
"Indeed, it not only catches others by surprise but also conserves the Immortal Essence within," Xu Nian nodded.
Maintaining a domain also consumes Immortal Essence.
Xu Nian just tried it and found that he still couldn't release the domain at the moment his sword was unleashed.
"It seems my cultivation still has a long way to go," Xu Nian murmured to himself.
His eyes suddenly shone with determination.
He couldn't defeat this Titan Vajra Ape in a single strike either.
