"Burp."
Zhao Sen belched satisfactorily.
It was the fullest meal he had eaten in half a year.
Actually, there was quite a bit to eat in the hospital canteen, but most of it was perishable vegetables and meats, and by the time the doctors finally cleared the zombies outside, the food inside had spoiled.
What remained were basically some grains and oil.
But not much either.
After all, this was a canteen, not a storeroom.
The bulk of their daily raw materials had to be acquired through procurement.
Plus, initially, no one had expected things to turn out the way they did today, so there was inevitably a lack of long-term planning in food rationing, which further led to everyone suffering from hunger later on.
This situation continued until Zhao Sen discovered and successfully extracted a large amount of that extraction solution.
With the help of the extraction solution, they were able to venture out of the hospital.
And explore the surrounding area.
