After all, the two big bosses' aura was the opposite, rejecting each other, and whoever lost this medium would die.
Gabriel never expected Ainsley to obediently become his medium, and so, Gabriel wanted to use the last resort—
Forcefully occupying Ainsley's body and replacing Asmodeus.
Once he succeeded, even if Ainsley hated him, she could only listen to him because he was the one in control over Ainsley's body and whether Ainsley could regain control was up to him.
Gabriel shouted those words just to shock foes and friends. He used the shock he brought from his words to rush to Ainsley's place and forcefully tried to replace Asmodeus!
In the case of two consciousnesses trying to occupy one body, the stronger consciousness would win.
And Gabriel's consciousness now was at least 30% of the main body's true strength, while Asmodeus was only 1% or even less than 1%.
