"A mail was received in your guild mailbox."
The ice-cold, electronic sound crossed the distance of space and reached Rhode's ears in an instant. And after hearing the system prompt, Rhode, Canary, Mini Bubble Gum, and Icy Snow were shocked. It wasn't that the notification came like a bolt out of the blue, but that they were too confused.
The guild mailbox was a special mean of distributing messages within the guild and could be considered a type of group chat. In the guild, whenever Rhode needed to gather men, he would send a group message and everyone would receive it. However, after arriving in the Dragon Soul Continent, he didn't touch the guild mailbox at all.
Firstly, no one else had this function. And secondly, he could summon those who were connected to him directly by using spiritual communication, so over time, he didn't bother with it. And for that reason, they were at a loss after hearing the system prompt and only reacted after a good while.
