As everyone knows, there is no such thing as telephones or telegrams in this world.
The fastest way to transmit information is through a Teleportation Circle, which directly transports people to deliver messages, whether orally or in writing. That is the quickest method of message delivery.
Today, only the Necromancy Codex of the Elegy Poetry Society and the Magic Mirror of Amberser can perform real-time communication over long distances.
However, the Blue Algae Tribe is too small to afford the costly setup of a Teleportation Circle. Thus, Nepreis had no choice but to resort to the most primitive method and swim directly to the teleportation point.
He repeatedly instructed his people not to offend those two prominent figures from the realm of the undead. Then, Nepreis boarded his Conch Ship, hauled forward by a dozen dolphins.
These specially trained dolphins swam swiftly, but it still took half a day to bring Nepreis to another large Mermaid Tribe.
