Using the same material as tires, sucking out the air inside, storing food in there so it wouldn't contact the outside world, thereby extending the food's preservation period.
This method was really pretty unbelievable.
But analyzing it through the information they'd gathered, it seemed like operating this way might actually be possible.
As the only person in this group chat who didn't understand technology and only understood production and business, Viscount Roster was lost in thought.
After spacing out for a bit, he quickly typed out a line: "Preserving food, extending food's storage time—there seem to be many methods. High temperature, pickling, isolating air, and so on. How about we just establish a research institution? Anyone interested in this area can join, process different things in various ways, and ultimately arrive at the most effective plan."
