The Earth Mother created the world in three realms, each divided into four layers. Whether three or four, they all exist to protect the peace of the world. As time went on, doubts arose in people's hearts, and a few began to rise up in defiance. Before becoming an immortal, one must undergo an Immortal Trial. Only by passing it can one ascend. Once immortal, resisting the four layers should be easy enough.
