The case is full of doubts. They went to the beer company. Tsujiyong found many suspicious things, such as the factory ventilation windows, clues next to the coal warehouse, etc. He also speculated that the case was related to the secret society in the "Jewish Alley". Later, Tsujiyong made discoveries near the Jewish alley and learned that the three victims had spent the night at a woman's house and disappeared in the middle of the night. They had also bought anti-itch medicine. Tsujinaga concluded that they drank the mysterious evil spirit, developed a series of symptoms, and strayed into a Jewish alley and were brutally killed. At this moment, Tsuji Naga suddenly became ill. He drank something suspected of being a demon and left in a hurry. What will be his fate?
