Three Mage Kings had died.
The first Mage King that had died was the Myriad King.
His longevity had finally run out.
Back when Shang had met him for the first time, the Myriad King had only had less than 5,000 years of longevity left, and those had finally run out.
There was simply nothing that could have been done.
The Myriad King's Mana was put into an inheritor sphere and stored at a neutral place for the next great tournament.
What about the other two Mage Kings?
One of them was an old Mage King from the Twilight Dusk Family, while the other was the new Mage King the Lightning Manor had gained about 2,000 years ago.
The new Mage King had still been at the Initial Mage King Realm since it took quite some time to advance in the Mage King Realm.
One day, she was attacked by the oldest Mage King of the Twilight Dusk Family.
