Anna's biggest weakness right now is her complete lack of any ability to act or perceive.
Without the ability to act, she cannot avoid danger; without perception, she wouldn't even know if she gets hurt.
The meatball itself is a precise magical energy gathering structure. The outer periphery is a magical power constraint circuit, the interior is a vast magic that flows along a fixed route, responsible for condensing and differentiating organs, and at the core is Anna's soul.
If it suffers any damage, the outer binding circuit would break, and the magic inside will inevitably pour out from the fracture. By then, even the Golden Core Cultivators, let alone immortals, would not be able to save her.
Therefore, the primary task is to ensure that Anna, in this state, is not injured.
