The New King's Life-Chasing Sword

This is a murder investigation story that takes place in the magical world of Nizlit. The pursuit began on that night of a secret meeting soaked in blood - the crown princes appointed by the seven countries at the same time all died mysteriously on the same day. Every looming clue eventually points to a cruel truth that has been buried for a long time: it is related to the original reason for the establishment of the Seven Kingdoms, and it also points to the comeback of the descendants of the cruel demon king. "Your Majesty Nizlit, may the Seven Kingdoms remain safe, and may the lights stay on." Early the next morning, bad news spread throughout the seven kingdoms. Countless people knelt under the omnipresent, sacred and eternal Nizlit tree, sobbing silently and praying silently as if to the gods.
