As Ancestor Souls, they were soul lifeforms that didn't even have truly corporeal bodies. This kind of ability that could target souls would be most effective against them.
When facing Shawn's Soul Roar, they would be greatly affected, just like Ghosts.
The two Soul Ancestors fiercely shook as they were hit by the Soul Roar, and their bodies started to distort, apparently unable to maintain their shape.
This kind of great power was why Lin Yun was confident that Shawn could earn them 10 seconds, which was enough to do a lot of things.
The moment Shawn's Soul Roar echoed, the puppet already moved to take care of left totem, holding the totem with both hands as it pulled on it.
