Yang Jian had no way to refuse this mission.
Previously, he hoped other captains would handle the Ghost Lake incident, but now Cao Yang is compromised. One captain has already become ensnared, and coupled with the fact that Captain Yinzi from the Ghost Post Office was also confirmed missing in the Ghost Lake incident, it implies both captains' actions have failed.
So, who else can be relied upon?
If it is not addressed, the situation will worsen, and his Dachang City will also be unsafe.
Thus, a truly smart person should unite with other captains at this time, resolve this supernatural event in one go, and see if they could rescue the missing Cao Yang and Yinzi.
Although Yang Jian feared trouble, he still possessed the necessary big-picture view.
Otherwise, he wouldn't be able to hold the position of captain.
