ASTRID walked out of the makeshift dressing room and he was quickly assaulted by the cold wind. Although a filming studio planet was an artificial planet where temperature and weather could be controlled, there were still regions that had a fixed weather. Just like this snowy mountain.
He was wearing a thick insulated jacket right now. But he had to remove that once the shoot started. Not only the jacket would have to go away but also his shoes. According to the short scenario for this shoot, he had to walk towards the center of the lake with his feet bare.
Astrid could literally see his breath every time he exhaled. Showing just how cold it was here. It seemed that he had to finish this shoot quickly. Although almost all common illness could be healed by this era's medicine, it wouldn't change the fact that he would still feel like he was about to freeze to death while doing this shoot.
