Jormundgander was shocked to hear that voice. He was at the Initial Omega Detachment Stage, yet someone entered his castle without him even noticing them.
However, what truly stunned the Leviathan Primarch was that person entered the Leviathan World, despite Issac and Bahamut covering every corner of the void with their consciousnesses and soul force.
Jormundgander turned around to see the origin of the voice, and the moment he saw that man, his entire body tensed. He adopted a battle stance, and his energy was ready to explode. His so-called savior was the same that shattered his body and soul and forced his cultivation to fall from the Middle Omega Detachment Stage to the Initial.
"What are you doing here!?"
Venganza stared at Jormundgander with a calm smile on his face. He did not raise his guard nor mobilize his energy, making it seem he did not consider the Leviathan Primarch a threat.
