After Young Master Shang and Old Zhao took the cream popsicle, they copied Lin Xuan and carefully took a bite.
Melted in the mouth, it was sweet and cool!
"How can this thing be so delicious?”
"Not only is it sweet and delicious, but it's also cool and refreshing.”
Young Master Shang couldn't help but praise after he finished the entire cream popsicle.
There was nothing more blissful than eating a popsicle in the hot summer!
"It's called an ice popsicle."
"It was me who invented the divine weapon to relieve the heat."
Lin Xuan introduced with a smile.
Due to her health, Gongsun Liji had not been blessed with cold food these few days, so Lin Xuan ate cream popsicles and iced candied fruits downstairs alone.
"Ice…rod?"
"This thing really does help to relieve the heat. I just ate a few mouthfuls and I didn't feel hot anymore.”
"I wonder how Shopkeeper Lin made this popsicle. I also want to go back and try it.”
Old Zhao cupped his fists at Lin Xuan.
There was also an icehouse in his manor. Although it was not as big as the icehouse in Ying Zheng's palace, it was enough to make hundreds of popsicles.
In this era, only high officials or nobles had ice cellars in their homes.
Moreover, the ice in the ice cellar was stored in winter, so even Ying Zheng was reluctant to use ice to cool off the heat.
Because for Ying Zheng and Zhao Gao, ice was limited, and if they used it up in advance, it would be useless.
In this era, almost everyone picked ice in winter and stored it in an ice cellar for summer. Only Lin Xuan was different.
Lin Xuan used the saltpeter ice making method. It had nothing to do with winter. As long as he was willing, he could make ice at any time.
"The production method of this cream popsicle is very troublesome, and it requires a lot of expensive raw materials.”
"In fact, Great Qin doesn't even have some of the ingredients, so I suggest that if you want to eat it, you should come to the wine shop.”
Lin Xuan patted Old Zhao's shoulder and suggested with a smile.
"Alright, alright."
"If I learn how to make cream popsicles, wouldn't I be stealing your business?”
Old Zhao smiled apologetically.
He thought the popsicle was too delicious, so he was a little impulsive when he spoke and forgot the rules.
With that, Old Zhao tactfully punished himself with three cups as an apology to Lin Xuan.
"Shopkeeper Lin, I remember that your tavern has only been open for less than two months.”
"This ice is very expensive. When mining in winter, not only does it require money, but it also requires power.”
"I remember that you always said that you didn't want to get involved in the whirlpool of power in the officialdom.”
"Could it be that Shopkeeper Lin has another way to make ice?”
Young Master Shang stared at Lin Xuan with burning eyes and asked with a smile.
He was a smart person, so he quickly realized that something was wrong.
Lin Xuan was only a commoner. Even though he opened a wine shop, only he and Old Zhao usually came here to eat. How did Lin Xuan get ice?
In Great Qin, if one did not have the power and wealth to harvest ice in winter, it would be as difficult as ascending to the heavens!
"Shopkeeper Lin, did you bring this ice back from the Western Regions?”
Old Zhao said in disbelief.
Other than the Western Regions, he really could not think of where Lin Xuan could get ice from and store it until now.
Every winter, the royal family would pick the ice first, followed by the dignitaries, and finally the rich merchants.
Lin Xuan was dressed in white a few months ago. How could it be his turn to pick ice?
"I'm alone. How can I bring Bing back from the Western Regions?”
"And who said that if you want to get ice, you have to mine it in winter and then store it?”
Lin Xuan asked seriously.
After saying that, Shang Gongzi and Old Zhao looked at each other. They really could not think of any other way to obtain ice other than harvesting ice in winter.
"Have you heard of a method of making ice called the saltpeter ice making method?”
Lin Xuan asked.
Young Master Shang and Old Zhao heard this crazily, indicating that they did not know what Lin Xuan was talking about.
They didn't even know what saltpeter was, let alone the saltpeter ice making method.
When Lin Xuan saw Young Master Shang and Old Zhao's dumbfounded expressions, he took out a few pieces of saltpeter from his storage space and handed them to them.
"This is saltpeter, a mineral.”
"They can be found during mining. They like to stay under the low temperature of the walls.”
Lin Xuan pointed at the saltpeter that was as white as frost and introduced it in a low voice.
Young Master Shang and Old Zhao nodded thoughtfully.
However, Old Zhao quickly asked.
"Shopkeeper Lin, although this saltpeter looks good, what does it have to do with ice?”
"Moreover, this saltpeter doesn't feel cold to the touch. How can we use it to make ice?”
Old Zhao scratched his head and said in puzzlement.
Young Master Shang couldn't think of a connection between saltpeter and ice.
"Do you know about calcium nitrate?"
"When dissolved in water, calcium nitrate will absorb a large amount of heat, causing the surrounding water temperature to drop until it freezes.”
Lin Xuan said.
Young Master Shang and Old Zhao were dumbfounded when they heard this. They did not know what Lin Xuan was talking about.
Seeing this, Lin Xuan did not talk nonsense about the principle of making ice with saltpeter. Instead, he found a wine pot filled with water and threw it into half a pot of water.
"It's useless to say more."
"Just watch what I do next and you'll understand.”
Lin Xuan said as he added saltpeter into the water tank.
Young Master Shang and Old Zhao immediately stood up and walked towards the water tank.
"Shopkeeper Lin, why do you keep throwing saltpeter into the water tank?”
"After throwing the saltpeter into the water tank, can the water in the water tank still be drunk?”
Old Zhao said worriedly.
When Lin Xuan heard this, he ignored Old Zhao and slapped the back of his head ruthlessly.
"It looks good!"
"Why are there so many questions?"
Lin Xuan reprimanded sternly.
Old Zhao was so angry that the veins on his forehead bulged, and the qi in his body surged like a river.
No one had ever dared to hit his head like this. Lin Xuan was the first!
Just as Old Zhao rolled up his sleeves and was about to teach Lin Xuan a lesson, Young Master Shang suddenly raised his hand and stopped him.
Old Zhao was very aggrieved. He rubbed the back of his head unwillingly and forgave Lin Xuan on account of Young Master Shang.
After half an incense stick of time, Lin Xuan took out a wine pot from the water tank and handed it to Young Master Shang.
"I don't believe that you can make ice like this.”
" Young Master, let me help you open it…"
Old Zhao had just finished speaking when he was shocked speechless by the ice in the wine pot.
So it could really make ice like this?
And it only took less than the time for an incense stick to burn from beginning to end?
Young Master Shang and Old Zhao were beyond shocked. They could not believe their eyes.
If they hadn't seen it with their own eyes, they wouldn't have believed that ice could be made like this!
