Due to the last invasion by otherworldly creatures, the newly cultivated Plantation Area just outside the Magic Capital Base was destroyed by the otherworldly invaders, leading to a short-term food shortage within the base.
But it was just a short-term shortage, for ever since the Imperial Court reestablished contact with all bases, even if a base encountered an unexpected shortage of resources, it could redistribute supplies from surrounding bases for support.
The supplies redeployed from other bases could only meet the basic daily needs of the survivors in the disaster-stricken base and certainly would not be enough to allow for the processing of any secondary food products.
It is known that within the entire Magic Capital Base, it's not only the Thompson Family that possesses brewing technology, but because of the lack of grain, no one would consider brewing recently.
