Nald's decision to first break through the seal of the Mystery Saint was certainly great news for John.
Throughout Nald's action, John did not hinder him.
This was because John was acutely aware that if Nald could successfully break the seal of the Mystery Saint, he could use this opportunity to make his escape as well.
Nald's current condition was extremely dire, and John could tell that Nald's madness had intensified significantly.
It wouldn't be long before Nald might completely succumb to utter insanity.
John felt that his first priority should be to prepare for his own defense.
If he couldn't even ensure his own safety, then winning the upcoming battle would be impossible.
With the assistance of the Book of the Astral Realm, Nald quickly broke through the seal of the Mystery Saint.
After breaking the seal, Nald appeared to be overjoyed.
