It must be said, the Sacrifical Ceremony of the Spirit is quite a spectacle.
At least in the main world, Su Lu no longer wanted it.
"Compared to the 'Blessing of the Demon' ritual, the Spirit Sacrifice ritual is okay, just paying homage to the ancient spirit realm, with no danger of attracting the attention of the evil gods... The rituals required by [Illusionist] are even more challenging..."
"As for this 'Spirit Sacrifice', there are requirements for the sacrificer, the sacrifice, and the environment. It must take place in the world at the Dawn of the Gods, which dashed my hopes of choosing any low-risk world in the Twilight of the Gods with ease."
"The sacrificer should preferably consist of a certain ratio of Transcendents, and the higher the level of the sacrifices the better, as this relates to the success rate of subsequent promotions... However, for me, this doesn't appear to have any effect, as I have never failed when it comes to occupying the attribute column."
