Yu Fangzhu blankly stared at the letter in his hand. It didn't contain any other hidden messages aside from these few words telling him to come to a cave in the mountain. Of course, any sane man who was capable of suspecting he was being messed with will try to ignore these words and start his day like nothing happened.
But Yu Fangzhu knew he couldn't ignore it. The message was vague but to him, it was filled with hidden messages. After all, there were only a few people who knew of the cave in the mountain.
Aside from the Tianli cave that his family has been trying to hide from everyone else and covet, there was another cave that his mother found when she was younger. At that point, his mother wasn't married to the emperor and was in love with another man. That man was just a budding soldier and because of that, her family forbade her from further interacting with him.
