At this moment, he had naturally already received support from others like the Virgo. Thus, he moved to the boundary of the barrier and deployed the defensive Black Magic 'Ice Wall Technique' that came from the Virgo's crystal.
[Ice Wall Technique: Mid-tier Ice-element Black Magic, condenses a wall of unbreakable ice in front of the user, blocking the path of units. Any creature that comes into close contact with the ice wall will fall into a frozen state. The range and height of the ice wall depend on the magic power input.]
This black magic didn't have many laudable features. It simply creates an ice wall that blocks passage. Moreover, this wall doesn't restrict teleportation abilities.
