Malin checked its injured leg and finally decided to heal it—if the falcon had also been contaminated by Chaos, then healing it amounted to its Purification.
If it hadn't been contaminated and had simply become a spirit, it would be able to survive.
The reason Malin chose to save the falcon was that he was unclear whether the things he did while diving deep would affect the world in the future. With safety first in mind, Malin had no choice but to do this.
The Restorative Spell and limb regeneration healed the falcon's broken leg without any discomfort. Malin retreated to a corner, wove a protective net with Spell Formation, and then ordered the young shoots to let go.
Fio and the others came before Malin, forming the strongest shield wall.
Eventually, the falcon stood up again. It flapped its wings and, instead of attacking Malin, went to the side of the room to rebuild its nest.
