Age of Obscuration

Detective Chen Mo of the Crime Unit took over a bizarre death case. Wei Yuanshan, a professor of religion at Jincheng University, was found dead in his study - cardiac arrest. Ten symbols were carved on his chest with a letter opener. A dense spiderweb-like relationship diagram was connected with red lines on the entire wall of the study, and ten tarot cards were spread out on the table. Forensic doctor Fang Yuan's conclusion silenced everyone: there was no poisoning, no trauma, and the cause of death was fright.
