Marina sought help from a psychic because her hair was severely tangled. The psychic told her that the tangles stemmed from unresolved psychological troubles and proposed a method to guide her into the Yuanshen Palace, helping to adjust her spiritual well-being. However, entering the Yuanshen Palace is not simple; Marina must challenge herself, find a person with blue hair, and consume the essence from their brain to complete this 'like-for-like' ritual, opening the path to the Yuanshen Palace.
