Tons of earth flew into the sky, as the Black Dragon unleashed a long-prepared eighth ring spell—Soul Enslavement—to forcibly enslave the opponent.
The entry-level Soul Enslavement could only enslave three life forms, and Udi had already used up the three slots.
However, they could be vacated once used.
Udi directly released Evil Giant Nurraf from enslavement.
The Evil Giant, having been freed from enslavement, did not immediately rebel against Udi, as it still held a Servant Contract bestowed by Udi.
Soul Enslavement is more terrifying due to its coercive nature and ability to influence the minds of beings to some extent, whereas the Servant Contract, although it can control life and death, is not as domineering as Soul Enslavement.
But having witnessed the terror of the Black Dragon Lord, the Evil Giant Nurraf, as long as it remained clear-headed, did not seek death.
