They solve crimes in traditional Chinese clothing, yet are bound to the Book of Life and Death System.
Save one wronged soul from history, and the modern world gains another chance at survival.
Misjudge one case, and a loved one will die in their place on the spot.
To save his comatose younger brother, former criminal investigator Chen Feng is forced to bond with three eccentric geniuses dressed in traditional Chinese clothing:
a professor who can see through people's hearts, a painter who empathizes with all things, and a female assassin bearing a curse.
From then on, the four become one another's only support in both history and the present day. They race for their lives through bloody cases in the Song, Tang, and Ming dynasties, as well as the Republican era, using modern knowledge to crack puzzles and historical wisdom to save their loved ones.
Then the mysterious organization Mirror presents an offer they cannot refuse:
"For the next case, deliberately reach the wrong verdict."
"The reward: your younger brother will wake up immediately."
I refused.
So they revealed their trump card.
I saw the ultimate case file, and the name on the signature line belonged to my father, who had been missing for many years.
At the end of the file, the System marked the final mission in bloody letters:
[Go to the scene of the 'Original Sin': the 1923 Shanghai family massacre.]
[Failure penalty: every team member's loved ones will be erased from existence.]
Only then did I understand that what we were risking our lives to save others from was a bloody curse spanning a hundred years.
And the person who may have written the first stroke of that curse was the very person I most wanted to find.
Now we must tear up this verdict written by our loved ones and face him in a final showdown at the beginning of history.
