The sealing ability of the Soul Core Box is considered an additional effect. Its initial design wasn't meant to function as a magic rice cooker casting the Demon-Sealing Wave.
One could only say it has such an effect, but it was likely a incidental part of the design, with the primary function leaning towards summoning. Therefore, the sealing effect can only capture one target... However, in Visakha's fully armed state, she herself is a walking armory.
——Her entire body, from clothing to weapons, is composed of divine artifacts.
——They are not merely tools, but special soul armaments with self-awareness.
Perhaps Gu Mo subconsciously regarded her as a whole at the time, but the Soul Core Box did not recognize it. Therefore, when he targeted Visakha, the sealing technique, driven by the immense Demonic Power of the Nine-tailed, precisely captured only Visakha, excluding all other divine artifacts on her body.
