In "Freeze Age 2", the elixir factory has unique functions and characteristics. It can produce medicines to treat diseases and protect the health of residents. Its operation relies on adequate supply of raw materials and skilled workers. The production capacity of the elixir factory can be increased through technological research and development, playing a key role in a difficult environment.
The elixir factory can exchange materials for food. You have a limited number of food areas in the middle and late stages (only deep wells... which basically means only 2), while the elixir factory is unlimited (it only requires labor, and you can use architecture to get one for heat energy). A lot of heating hubs are ignored. . . Almost 100 calories = 25 materials + 100 labor.
So it’s best to use it more in the later stages.
