Kungunir!
Right!
Levin suddenly realized, Marvin had received Odin's blessing.
"Kungunir is a Rule-class Divine Artifact, just like Thousand Faces Mask, Mermaid's Tear, it can break established rules and produce unexpected effects."
Baji said, "Normally, the Mirror Demon exchanges illusion with reality, making the seals unbreakable because changes happening to objects in the Mirror World correspond with reality, while the Holy Sword of Wisdom in the Mirror World isn't part of reality."
"It's a clever use of rules, without overt power to change or ignore the rules, one can't pull out the Holy Sword of Wisdom. Unfortunately for you, your older brother happens to have an artifact that breaks rules, hence he shook the seals."
Kungunir viewed the Holy Sword of Wisdom as the vessel!
Whether it was the Holy Sword of Wisdom resisting the erosion by Kungunir, or Kungunir assimilating the Holy Sword of Wisdom, it would affect the seals!
