The Primus separates a Mixed Yuan Bead into a Spirit Seed and a Demon Pill via an extraction method. The Demon Pill will result in the creation of a devil who will pose a threat to humanity, but the Spirit Seed can allow King Zhou to be reincarnated as a human so that he can build a new kingdom. The one who is intended to be the hero is Ne Zha, but instead, he becomes an incarnation of the devil due to the fact that the Spirit Seed and a Demon Pill are switched.
