The Case Solver II 拆案2 Episode 9

Kang Yichen identified the dean as a "vampire", but the dean was temporarily cleared of suspicion after self-certification. And because Li Han was superstitious about foreign countries, his failure to invite foreign exorcists to catch vampires became a laughing stock, so he had to ask Gu Yuan and Kang Yichen to investigate the case again. Gu Yuan and others set up a net, and finally the "vampire" was caught after attacking the dean. This person is Xiaohu who has been missing for a long time. Xiaohu admitted to the crime and said he was in pain because of his craving for blood. After investigation, Che Suwei found that Xiaohu had hematoporphyria, and its pathological symptoms were the same as those of vampires in the movie. Gu Yuan felt that there was something else in the matter, but Li Han insisted on executing Xiaohu in order to take credit. At a critical moment, Lu Shijun woke up and pointed out that the murderer was actually the dean. It turned out that Xiaohu and other children became ill because they ate bad food from corrupt officials, and the dean took revenge for it. In the end, the dean died on the road of escape.
