Heroic Spirit Hall, underground level.
The Heroic Spirit Realm, which only Law Realm experts could barely observe, was located beneath the great hall.
Existing between reality and nothingness.
Within the Heroic Spirit Realm, there were no heroic spirits; it seemed to serve as a medium to connect with and awaken the heroic spirits still existing within the Eternal World.
Mu Yuan pondered.
He walked to a massive array map used for summoning heroic spirits.
In the center of the array stood an ancient stone platform, naturally empty. The premise of 'specific summoning' was to place on the platform a relic closely associated with a particular heroic spirit.
Mu Yuan placed the ancient, tattered Book of Undead on it.
This relic had a higher association with a Holy Realm Great Power user, and its owner was likely at least a Great Monarch Level, if not a True King Level!
He naturally wanted to try this holy relic first.
"Activate!"
"Specific Summoning!"
"Ding!"
