482 Chapter 22

"This one? Is it too... simple?" Sui Xiong asked. Looking at the gray-white box, Sui Xiong frowned.

Arcaian said, sighing, "In a month, this one is the most reliable one among the submitted ideas."

Sui Xiong gently pressed the box with his tentacles. The box opened, and there was no cold air inside. It was just at a normal temperature. This surprised Sui Xiong a little, so he asked, "Shouldn't it use a cryogenic refrigeration method?"

"It's difficult to use a cryogenic refrigeration method on a large scale, and the storage time and storage costs are much higher," Arcaian answered. At the same time, he took out a delicate silver-white box. "This is a refrigerated box that is used to store high-end foods. It is worth about 500 gold coins. Even people with high incomes are generally only willing to rent one. It can save food for about two days. However, in fact, after a day, the taste of the food will obviously go worse."
