The original plan was that the Japanese army would send a special envoy from Xinjing to Dongning to investigate. This person had been instigated by our party to rebel. Song Zhuowen's task was to contact him after he arrived in Harbin and hand him the tools needed to complete the task.But this man was timid in the face of battle and did not dare to go.
Song Zhuowen decided to go to Dongning in place of the special envoy, so he asked Guan Xue to quickly injure the envoy (Guan Xue agreed in order for the Secret Service to intervene in this mission), and went to the fortress instead of the envoy.
Asano Daigo and Guan Xue agreed to this plan for their own interests.After Song Zhuowen arrived in Dongning, he began to carry out the mission. Although it was difficult and dangerous, the progress was relatively smooth, and he discovered Japan's even greater ulterior secrets hidden in the fortress.
Song Zhuowen, acting as a special envoy in Dongning Fortress, was investigating the leaker while performing a drawing task. In the end, the investigation came to an end and the leaker was not found, so he was ready to return.
