Certainly, they were going to investigate, but five years was a long time. Back then, Liu Shimei was still young, and there were not many things she knew. Moreover, she had blocked her inner self for a while after losing her brother, unwilling to hear about any of these sorrowful past events.
So, there were no leads from her!
As for Liu Fuyun...
She decided to take it slow and set it aside for now. Since someone was determined to guide her to investigate Liu Quan's death, it would eventually come to light.
She would wait.
The next morning, they boarded a carriage heading for the Liu family's ancestral tomb.
Before they even left the inner city gate, they saw someone hastily catching up. He ran while panting heavily, shouting, "Wait, my wife!"
Using the same old formula, with the same familiar taste, Liu Shimei quickly signaled to Lu Ying, who was driving the carriage, "It's King Dun Yu. Stop and wait for him!"
