The case needs to be investigated, and so do you and me.
The world is like a copper wall, and they are the ray of light that shines into each other through the cracks in the wall.
The world of Chu Zhaoling consists only of "useful" and "useless", "deserving of life" and "deserving of death". Until he met Wei Ran - the scholar who tried to inquire about the truth of nature in an unsolvable puzzle with a few copper coins and a compass.
Wei Ran has seen too much filth hidden under rules and regulations. He originally thought that Chu Zhaoling was just another royal weapon stained with blood, but for the first time, someone used his body as a shield to protect the evidence in his hands, and his body was covered with bruises.
A missing official case that implicated the royal family and shaken the country forced two people who should never have crossed paths to go together.
He taught him the rules of survival in the shadow world, and he showed him that there was also a glimmer of light above the ruins.
They are the only accident in each other's plans, they are the sword and shield back to back in desperate situations, and they are the hand that can pull each other out of the abyss when they sink.
When the outcome of the conspiracy points to the "evil" that must be protected, should you stick to your loyalty or fulfill the light in your heart that has never been extinguished?
