A crime thriller centered on a serial killer during the Wan Li Period and trying to figure out why the murderer did what they did in relation to the crime that occurred 20 years prior.

What I love;
1. The cinematography and costume is meticulously crafted and makes you feel the common life in the Wan Li Period. The portrayal of being a commoner, bailiff and official is close to realistic which is not common now in the drama.
2. Each episode is important to solve the crime so you need to be attentive in every scene and every character in the drama.
3. Wonderful performance of every character.

Lastly: LU ZHI

I fell in love with Sangeng in the first episode because of his morals and exquisite face expression. And now Lu Zhi appears, a beggar who was taken in by Lu and raised in his home. He was presented as a good-natured, capable household manager who may have a better future if commoners in the current Dynasty were given more opportunities to advance. You will be able to relate to his character, who is willing to serve everyone around him and simply wants to establish a stable family. However, I believe that he is pushing his luck and running the risk of harm due to all the secrets he possesses when he "accidentally" or by pure coincidence discovers the secrets of others. However, he stayed devoted and compassionate, even trying to mediate their differences, but life is unjust.
He was driven to the brink in some way, and like the other reviewer noted, he would be a wonderful person if he could just have a guardian who could refer to him as a father figure. I was greatly impacted by his nuanced character, and I doubt I will forget him for a very long time.

Overall, it was a fascinating journey of investigating crimes in a subdued setting. This is not an action-packed drama, so I'm not sure if it's for everyone, but its strongest feature is understanding each character and how their actions lead to the tragic conclusion of a horrific serial killing.
Try it guys!
