The Sea of Consciousness!
Also known as the sea of consciousness within the brain that common people talk about, some cultivation sects call it the Mud Pill Palace.
This is where a person's Divine soul resides.
There should only be one Divine soul, but within Dai Jiajia's Sea of Consciousness, there is another independent Divine soul of an extremely high essence, which is squeezing another weaker Divine soul into a corner of the Sea of Consciousness.
This powerful Divine soul seems to have been female in life and is now deceased, yet the Divine soul has not dissipated and, for some reason, has taken up residence within Dai Jiajia's Sea of Consciousness.
However, this powerful Divine soul has not destroyed Dai Jiajia's Divine soul, nor has it devoured it. Instead, it nourishes Dai Jiajia's Divine soul with its own Soul Power, protecting it from harm. It doesn't seem particularly malicious.
