"Cooling on." Maya immediately activated the suit when she saw Clone Theo jumping into the main vent.
Theo also severed all the senses, not wanting to feel the extraordinary heat.
The only reason he accepted the cooling suit was to make sure his clone could withstand the heat of the magma and didn't get burned. If his body was that strong, he wouldn't need to rely on the suit.
As soon as Maya activated the cooling inside the suit, he saw the metal plate begin to be surrounded by ice. This ice wasn't the product of normal physics. Instead, it was similar to the shield from his Ring of Honor.
So, the ice endurance was far better than the normal ice that would be evaporated upon having a close contact with the magma.
Theo then used his Telekinesis to speed up, not wasting a single second because he didn't know when the suit would be reduced into ashes.
