The Eldest Prince's trip to Hejian Prefecture is indeed related to the murder case, and the one orchestrating everything behind the scenes is Prince Jing.
The Third Prince had previously thought he had outsmarted the Eldest Prince and was probably feeling quite pleased, but who would have expected there was a "yellow sparrow" behind?
"Your Highness! What about the treasure map?" The adviser Tao Lei Yuan cautiously glanced at Prince Jing, his heart ablaze with excitement.
Prince Jing raised an eyebrow, "It is unclear which faction now holds the treasure map. To get it, it will likely take some effort."
Hu Maoshen studied Prince Jing, doubt brewing in his mind.
Since it's unknown into whose hands the treasure map has fallen, and Prince Jing is not anxious, could it be that he already has a clue?
The treasure map that Tao Lei Yuan mentioned was precisely the reason the Eldest Prince went to Hejian Prefecture; there was indeed something suspicious about that case back then.
