Six more or less normal people came together for some reason: "Li Ruonan" who hides secrets deep in the city, innocent explosives expert Li Ruoyu, hacker sensory madman Zhang Xing'an, Wang Xu who watches the scene during the day and creates the scene at night, Hou Linhai who is extremely strong and naive, Qian Xueyang who does not panic even if the sky collapses at extremely fast speeds. Then, we investigate the case together and... Hurt each other... Ourselves and others.
The open thread is a series of Tarot cases, and the hidden thread is the family affairs of these people.
Concept: Tarot cards have upright and reversed positions, and everyone's heart also has light and dark sides
