In such rainy weather, the snipers of the Great Tang Empire were in a somewhat better condition than those of the Dahua Empire.
They were issued with self-heating packs and warm water bottles, and had observers who could prepare some things in hidden places, so Tang Fei was still very comfortable in the sniper hideout he had found for himself.
Beside him was a warm water bottle, which allowed him to feel warmth at any time. Additionally, his clothes were very effective at keeping him warm, thanks to the chemical industry level of the Great Tang Empire.
It's not an exaggeration at all; due to technological advancements, many new materials had begun to appear, and the first to benefit were the soldiers fighting on the front lines. Materials that blocked wind and rain helped them maintain body temperature and also allowed them to fight more comfortably.
