The public who was watching this situation unfold was in high tension. Daimon Citizens were cursing that their Interim Leader had did so much for the Parry City Citizens and their military had decided to respond as such.
The citizens especially the military had seen Jin not just as a leader but as a saviour for them in times of darkness when everyone had abandoned them to fend for themselves. His decision was unorthodox initially when the citizens heard that the military was going to be deployed in the north.
But those insiders who were working to procure supplies during the assembly could see that he did not have such an intention to fight them. The bulk of the Daimon military was also initially against the assembly as well since they knew that the creation of the latest outpost was such a poor excuse. The creation of the Southern Daimon Dungeon Outpost had no problems at all and even if monsters do leak out, they did not entire military to be out in force.
