Tang Wen first took out a piece of cured meat from a small bag and briefly introduced it.
He then had someone bring two basins of water. Taking saltpeter from a large bag, he demonstrated the technique of making ice on the spot.
The hall fell silent.
Everyone stared at Tang Wen, their eyes filled with shock.
He said he would perform a great service, and he actually did.
And he didn't even make them wait a minute!
The Queen, disregarding her status, stepped down from her seat. She picked up a piece of the ice and examined it from all angles, her face full of astonishment.
"Oh, and the saltpeter can be reused. I've already tested it. We can build an underground ice cellar, and the temperature inside will be no different from winter!"
After speaking, Tang Wen ordered someone to bring a brazier and an iron pot. Using evaporation, he recrystallized the saltpeter.
"Celestial Blessing Camp!"
