The dark apparitions were extremely familiar with the aura of Devil Transformation.
But it was astonishing that he used Devil Transformation so quickly.
Thud! Thud! Thud…
Chaotic and dull sounds were heard continuously from the arena. The nine dark apparitions were undergoing Devil Transformation at the same time, so the sounds they made were different. When the sounds merged together, it sounded like someone hitting a drum. It was chaotic and dull, as if it was hitting their hearts. The hearts of the people present started palpitating furiously.
The expressions of the weaker dark apparitions changed slightly. They immediately activated their Forces to block the sound.
Even some dark apparitions who had reached the high-tier devil emperor level had grave expressions on their faces. Their gazes flickered as they looked at the arena, trying to see what was happening inside.
Boom! Boom! Boom!
