Ainsworth was truly patient. Even when he witnessed Lucien using his trump card to freeze time, he didn't even assist, despite Xalvureth and Varnak's intentions to interrupt Lucien.
Of course, Ainsworth was confident that a capable SSS-rank Awakener like the Archmagister Supreme wouldn't be interrupted in casting even an SSS-rank Forbidden Magic Spell.
It proved that his confidence in Lucien was truly correct. Lucien successfully cast the Forbidden Magic Spell: Absolute Zero and froze time in the surrounding area.
The most straightforward method to avoid the effect of this forbidden magic spell was to be outside the range of Absolute Zero before it was cast.
Unfortunately, Ainsworth had to be within the range of Absolute Zero. He was even surprised that, despite being in the void, he was affected by the frozen time and stilled motion caused by Absolute Zero!
Fortunately, Ainsworth already expected that.
