"Domain Masters"
People in the domain realm might seem weak to these ancestors.
However, for other ability users who were still below the domain realm, just an entry-level domain realm ability user could already crush them to death several times.
Even if the range of the domain were as small as a backpack, as long as someone's body part entered that domain, they would immediately die.
It was easy to make someone's head enter the bag-sized domain, and so, it would be as easy as killing ants to kill these people.
Even if Ainsley was extremely strong, she had also personally experienced how it felt to enter someone else's domain.
Wilhelm from the blood clan, that little prince who was actually already a few hundred years old and had already turned unto a spirit, was one of the examples of how strong a domain realm ability user could be.
