“Improves virus resistance and increases local temperature together.”
The High-heat Furnace is a seasonal building in Last War Survival. This building is used to heat your base and increase its resistance to viruses. As you upgrade the Furnace, it improves both the virus resistance and the heating capacity of your base.
Virus resistance and heat are major factors in battles, so it’s recommended to keep the Furnace well-upgraded.
