The letter from the old marshal.
This is a hidden letter that is unknown to anyone else from the Long Clan. If we are going to talk about its source one must talk about what else happened on the day the old marshal was assassinated and was brought back to the borders while at the brink of death. General Gu Ying, the former barracks captain, was the one who had welcomed back the old general and the others when they had returned to the city.
At that time, the old marshal was bedridden due to his injuries and he had been resting letting the doctors treat him. Maybe it was at that time that he had heard a voice in his mind. It was a surreal experience for a mortal like Long Huang but he couldn't deny it as he was able to converse with the owner of this voice. The language it had spoken was something he heard for the first time. But as if something is directly translating it to his head, he was able to understand the words spoken to him.
