Chapter 455: 454. Meticulous logic

"Yes, the word for 'salt' did not exist earlier. People back then realized that meat cooked with salty water tasted better, so they continued the practice. Brine is simply sea water or well saltwater, so 'brine' was used instead of the word for salt," Fang Yining said, holding the vessel thoughtfully. "Does that mean this vessel was used to hold sea water?"

Professor Cao did not speak and slowly shook his head.

He was unsure of this detail.

"Not sea water."

"...Huh?"

Hearing a clear, cold female voice coming from above, Fang Yining raised his head in the direction of the voice and spotted Tang Shu.

"Junior Sister Tang, why do you say it's not sea water?"

If even Professor Cao couldn't be certain, how did she know?

Since it had been determined that this was a vessel for holding salt, what else could it be if not sea water?

Professor Cao, too, became interested, casually cleared a stone nearby, and sat down.
