When there were only the three of us and a couple of patients left in the ward, I asked the two to guard the door as I do my work. I looked around and saw that there were only seven patients in this ward. Three of them have amputated limbs (2 have lost a leg and 1 an arm), 2 became blind and 2 had severe burns and hearing issues after being hit on the head and other parts of their bodies by burning rocks hurled by the enemies.
I casted a continuous spell to increase recovery rate inside the entire hospital and silently changed all the light orbs inside the hospital with healing light orbs. In a span of 10 minutes, I regrew limbs, returned the ability to see and repaired the skin and hearing of the 7 patients. They were still unconscious so my two guards didn't even notice that they were cured and that many other things have changed.
