Ice cellars were used by the ancients to store ice, and in winter, there were icemen who retrieved the ice and snow and stored them in the low-temperature moisturizing cellars for summer heat.

If this is two hundred years ago, it can only be built by large families, and if it is a thousand years earlier, only the prince's and grandson's house can have an ice cellar to store ice.

In the Northern Song Dynasty, after many things began to be civicized and universalized, all well-off families generally have ice cellars for storing ice, that is, people who do not have ice cellars can also go to the ice warehouse to get ice, but it costs some money, and it is similar to "taking ice with tickets", that is, there are no ice bills (similar to salt bills and oil stamps from decades ago), and you can't buy ice if you have money.

As a result, citizens began to build their own ice cellars. (PS: The title of the people of the Northern Song Dynasty has indeed become a citizen, the Song Dynasty is really a very interesting era, if you are interested, you can Baidu it, to ensure that the surprises are continuous)

Drinking ice in summer began to become a citizen and universal, and it was no longer the privilege of princes and grandsons.

There is an ice cellar in Xin Xi's house, which was built when the third room was still prosperous.

The piece of ice in Xiang'er's hand was something that Xin Yu thought of by accident, and then asked Xiang'er to knock a piece down from the ice cellar and slowly polish it.

Originally, I was going to use glass, but the color of glass in this era was too dark and expensive!

The ice cube was touched with a biting chill, and the palm of the hand was quickly moistened with the water that had melted on the surface of the ice cube.

Shen Kuo looked curious: "Eleven Lang, this ice cube?" ”

Xin Xi laughed, looked at the sun in the sky, squatted down directly, beckoned to a few people, and motioned for a few people to come over.

Eve happily ran over and squatted beside Xin Xi, this kid had already been on zero guard against Xin Xi's family since he found out that he could eat enough when he came to Xin's house.

Thirty-six glanced at Xin Xi helplessly, and always felt that Eleven Lang was really out of grace when he squatted down at will. It's not etiquette, I opened my mouth, I wanted to say it and stopped, anyway, in the end, it was Eleven Lang who was reasonable, so I simply didn't say it.

Adam hesitated, but walked over and stood behind Xin Xi in a proper manner.

After several people stood up, Xin Zhen smiled faintly, and tried not to pretend to be forced to speak: "It's all optimistic, next, is the moment to witness the miracle!" ”

After babbling something that Shen Kuo and the others felt inexplicable, Xin Xi randomly found a dead leaf, adjusted the distance of the ice cube in his hand, and the sunlight was gathered into a small dot and fell straight on the dead leaf.

The ice cubes are still not very easy to use, and the small spots of light in front of me are a little scattered, and I don't know if it is not polished well, or if the ice cubes themselves are like this.

"Why is there a point of light there, brighter than the surroundings?!" Eve looked at Xin Zhen curiously, and had the audacity to say this.

Thirty-six frowned slightly, slapped Eve on the head, and said coldly: "Remember, before talking to Eleven Lang, you must add the title of head of the family!" ”

Eve covered her head and didn't speak, just looked at Xin Xi directly, her eyes were full of curiosity, and there was a trace of grievance that was deeply hidden.

Xin Zhen shook his head, too lazy to talk to Thirty-six about these humble questions, but said indifferently: "I will teach you in the future, now, just look at it!" ”

Time passed minute by minute, and just when everyone was a little impatient, a wisp of green smoke rose from the dead leaves.

The smoke drifted gently, and everyone's faces changed.

Eve's eyes widened, her face was full of surprise, it was Adam, who had always been quiet and indifferent, and there was a kind of curiosity in her eyes, and her gaze at Xin Xi was full of admiration!

Just when everyone's attention was highly concentrated, only a slight "poof" was heard, and a wisp of fire rose, and in an instant, the dead leaves quickly burned!

Xiang'er's face was full of surprise and exclaimed: "Eleven Lang, do you know how to do witchcraft?!" ”

Thirty-six was full of surprise, but at this time he whispered: "Be quiet! ”

If it's really witchcraft, if it spreads, it will inevitably be in trouble! Thinking of this, Thirty-six glanced at everyone, and his cold gaze stayed on Shen Kuo's face.

At this moment, he had the intention of killing people in his heart!

Being stared at by the cold gaze of Thirty-six, Shen Kuo only felt that he suddenly fell into the abyss, his back was sweating, and he naturally knew what the consequences would be if the news of Xin Zhen's demon magic was spread, and he could even say unceremoniously that Xin Zhen's life would be ruined because of this magic art, even if he had the world's first-class talent!

Eleven Lang, Eleven Lang, you know how to witchcraft, just hide it, why do you have to show me, now I say I'm tight-lipped, will you believe me?!

Shen Kuo only felt tired, yes, he was tired!

If you think about it carefully, isn't Eleven's name just a homonym for tiredness?! If you can leave alive, you will definitely retreat when you see Xin Shiyi in the future!

Xiang'er exaggeratedly stretched out her hand to cover her mouth, raised her head, and looked at Shen Kuo with the same viciousness.

The little girl's idea is very simple: everyone present, except for Shen Kuo, is her own person!

Xin Xi looked at the flames spreading on the dead leaves, and always felt that the atmosphere was a little wrong, and when he raised his head, he suddenly remembered that witchcraft may be a compliment to express surprise in later generations, but in the Northern Song Dynasty, it is not a compliment!

Although the Northern Song Dynasty was the most enlightened dynasty in Chinese history, there was never a shortage of superstitions!

Thinking of this, Xin Zhen's face was speechless, and he smiled helplessly: "What kind of magic is this, it's just that others are rare and weird, how can Brother Cun be so afraid of a tiger?!" ”

Shen Kuo was slightly stunned: "It's not witchcraft?!" ”

Thirty-six and Xiang'er also looked at Xin Zhen with a look of disbelief, while Eve looked at the ice cube in Xin Zhen's hand with curiosity, not knowing what she was thinking.

Only Adam, this indifferent and withdrawn little girl, said firmly in that immature voice: "If the head of the house says no, then it is not!" ”

Well, Xin Zhen turned around, looked at Adam with some surprise, touched the little girl's head, and didn't say much.

The little girl was touched by him, and she became a little cramped, and there was a hint of shyness on her stiff face.

Haha smiled, Xin Zhen said: "It's really not witchcraft, as long as you hold this ice cube, everyone can do it!" ”

"Spontaneous combustion without fire? Can everyone do it? Thirty-six expressed skepticism.

Xin Xi directly handed over the ice cube: "You can try it and you'll know!" ”

Taking the ice cube, Thirty-Six glanced at the ice cube suspiciously, found a dead leaf at random and placed it, and adjusted the distance under Xin Zhen's guidance.

As the minutes passed, a flame appeared out of thin air.

Everyone was dumbfounded.

Eve raised her head, looked at Thirty-Six again, touched her head, and then tentatively said, "Master of the house, can you let Eve try it too?" ”

Xin Zhen smiled and nodded.

Eve happily snatched the ice cube from Thirty-Six's hand and played with it.

Shen Kuo frowned slightly, and asked tentatively: "Eleven Lang, can this be the 'Ice Cutting Circle, Lifting to the Sun, and Ai Cheng Its Shadow' recorded in "Huainan Wanbi Technique"? ”
