"The secret spellcraft..." Igor felt unfamiliar with the word 'secret'.
"This is the second type of secret I just talked about, the Thunder Level secret. Such secrets are generally controlled by ancient families. They make agreements with the Kangen Family, who are responsible for the Soul Guardians, to let some Soul Guardians protect secrets that only their family members can master."
"Oh, so those are the unique skills of each family!" It was at this moment that Igor understood what it meant for some secrets to need the test of time...
"Of course, what's protected isn't just the family's unique skills, but also the family's hidden stories!" Coban Kangen shrugged, evidently finding the topic more interesting.
"You said the Kangen Family uses spellcraft to control these Soul Guardians. Doesn't that mean the Soul Guardians are bound?"
