Yan Fei found out that the real culprit in the recent bizarre homicide case in Shanghai pointed to remolded humans who lost his mind and had endless strength. Remolded humans killed citizens everywhere, causing social chaos. Huang Jun controlled the situation with the sound of the divine flute and thus, was promoted to the new mayor by Commander Duan. Huang Jun teamed up with Yan Fei to investigate the truth behind the scenes and the clues pointed to Japanese Unit 731. Yan Fei's father was also remoulded. Bai Ling who had been missing for a year suddenly appeared and wanted to cooperate with Yan Fei to work against Huang Jun. He pointed out that Huang Jun is a very capable psychopath. He used the Japanese laboratory to resurrect his father Huang Lang more than one year ago and also remolded living people into undead warriors in an attempt to conquer the earth. Huang Jun even set Yan Fei up to make him kill his father by mistake. Despite all the difficulties, everyone finally defeated the Undead Team and Huang Jun with wisdom and courage.
