"General, a letter from the Imperial Court...."
At that moment, the Marshal of the Ghost Army, who was en route to the Northern Territory, immediately dismounted upon hearing the news and received the secret letter sealed with a magical imprint from the messenger soldier.
The Ghost Army uses a special type of confidential letter from the Ghost Temples, marked with the Ghost King's Seal. Generally, only those at the Ghost General Level or above can open it, and even Extraordinary Level magicians would struggle to open it with special means. If forced open, the letter would self-destruct.
Their communication relies on Messenger Ravens specially trained by the Ghost Realm. These birds fly exceedingly fast and can camouflage themselves according to their surroundings, making them nearly impossible to detect. They are the mainstream communication tool of the Ghost Army.
Given their scarcity, these birds are only used for urgent military reports, and this moment is of utmost urgency.
