999 Who is the Murderer

He Tienan (played by Zhou Wenjian), a young detective of the crime team, has long been famous in the police circles for repeatedly solving strange cases with his natural detective mind. Soon, Tetsuo accepted Jacky (played by Xu Haoying)'s self-recommendation. On the first day she took office, she encountered an incredible and strange thing - a stray dog ​​went to the police station to report a crime. Driven by curiosity, Jacky took Tetsuo and the dog and ran to the barren mountains. They found a horrific corpse of a man nailed to a cross in a dense forest. There were no witnesses or evidence, only a "certificate dog". The two then traced the residence of the deceased Big D, and found various signs, indicating that Big D's wife Alian and his friend Chen Hu were the most suspicious. Just when Tetsuo was pointing his finger at Lian and Hu, Lian's body was found near the dense forest.

The next day, the cross murder occurred again, and the victim turned out to be Chen Hu. The case fell into confusion, and more and more suspects were involved...
