After the sun fell, the world fell into the "Eternal Night Era", and the spiritual energy was polluted by the indescribable "outer god's will". Human practitioners need to practice by swallowing "distorted spiritual energy", but every time they break through, they may lose mental control and become monsters. The only thing that can resist pollution is the "Sequence Fragment" circulated in ancient times - a taboo book that records 108 paths to becoming a god. Each path requires nine levels of "spiritual trials" to be completed.
