By the time the Level 2 ability users frozen by the Unmelted Frost Bamboo Tree were sent back, few of them had regained consciousness. If Roh Baekjin hadn't had the presence of mind not to bring everyone to besiege Kim Haru, there might not have been enough people to deliver the food and escort these injured people back.
As for the ten remaining Level 3 ability users, aside from Roh Baekjin, the others had mostly recovered. The Pyeongseong Safe Zone Commander immediately assigned them to assist with infrastructure projects to prepare the Safe Zone for the coming winter.
Roh Baekjin's injury to his lower leg was severe, rendering him unable to move. For now, he could only be monitored and rest under Pyeongseong Safe Zone's supervision.
