Ning Fan's state of mind dove deep into the girl's memories.
The lowest grade of Soul Memory Searching Technique demanded the use of the caster's state of mind. If he failed to search the soul, he might suffer a backlash from it. Anyhow, he intended to search the soul once with the technique.
The girl's Sea of Consciousness was like a black void of space. In that pitch-black world, every fragment of memories blended itself into the color of black, making them indistinguishable.
Neither the path he came from nor the path to go could be seen. When walking in the empty black space, Ning Fan felt as if his state of mind was going to melt into the darkness.
What a strange memory seal!
It was sealed using the power of the Void Realm. It's no wonder that even Old Ancestor Dong Xu was unable to explore her soul. There's literally no one who could access her soul and memories other than experts at the Void Refinement Realm!
