Zhang Shaowu has already killed Zhao Dong, Li Junhao, Zheng Bin, and Zhao Kai.
This indicates that Zhang Shaowu had connections with these four people in that subcontracting project from 10 years ago.
However, Gao Xiang's investigations also show that some details of the subcontracting deal were unclear, and the information was incomplete, so it's uncertain if there were only these five people involved at the time.
Li Donglin suspects that Zhang Shaowu likely seized the opportunity to commit the crime immediately after Song Mingguang left the scene.
It's highly unlikely that only these five people were deceived in that incident years ago.
Now it's a race against time.
If Li Donglin and his team can find the associates from back then before Zhang Shaowu strikes again.
They might be able to take measures to prevent further killings.
Therefore, the team splits into two groups.
