Can it be achieved that as long as a creature created by one's subordinates remains undead, it can be resurrected from the Spirit network?
Judging by the current superpower abilities, it seems far-fetched, but at least there's a possibility...
And the remaining terms are mostly abstract "superpower" terms.
These terms Bai Yi doesn't even care to look at directly, not wanting to acknowledge them as superpowers.
Things like making people choke on water, whipping people, suddenly grabbing at people's hearts, and so on...
Each ability is useful in its way, but not very significant.
Also, unless performed at an abnormality level, any normally cultivated creature has resistance to these spells, most of which act within the body.
Even surpassing by one or two ranks can't make up for it, and since the rank is surpassed, there's no need to use such inefficient spells.
One could say there's not even a necessity to fuse them into spells for a witch to learn...
