After drinking a lot of hot water, Jack left the refuge with his Frozen Man.
Before leaving the refuge, Jack released the two robots, Maintainer I and Creator I.
The army's attacks had caused serious damage to Jack's refuge, Guardian of the Garden, and the particle anti-aircraft batteries. Jack needed Maintainer I to repair and functional upgrade so that Creator I could learn the principles created by the scientific research center and accumulate some experience for its future creation.
On the ground, although Jack was wearing protective clothing which had a strong thermal effect, his body was still unable to withstand the erosion of the cold air.
After the cold air was heated by the protective clothing, Jack still felt a sharp pain in the lung as if it was cut by countless knives.
But Jack's body temperature, heart rate, and breathing were normal.
For the time being, Jack wouldn't be paralyzed like Iron Man.
This made Jack more confident in his own health.
