"Well, I bought it from an old man, and he said that their watermelons ripen early."

Xue Wu said this, and Xue Mu believed it.

After all, it is not uncommon for watermelons to ripen early.

Xue Jun glanced at the basin of the iced watermelon just now, and found that there was a thin layer of ice on it, "Sister, why is the water in this basin frozen?" ”

Xue Wu took out a few saltpeters and showed her, "Do you recognize this?" ”

"Saltpeter?"

"That's right, put this in the water, and after the saltpeter dissolves in the water, the temperature of the water will be lowered, and when it drops to a certain extent, a layer of ice will form on the surface."

Saltpeter dissolves in water and absorbs a lot of heat, but Xue Jun probably doesn't understand what Xue Jun said, so it's relatively simple.

In fact, as early as the end of the Tang Dynasty, people discovered this and began to artificially make ice in summer. Some businessmen saw the opportunity and added sugar to ice to make cold drinks to attract customers.

In the Song Dynasty, there were more kinds of cold food in the market, and merchants also added fruit or juice to it.

However, the efficiency of using saltpeter to make ice is not high, and the government is still used to storing a large amount of ice in the winter and then taking it out for use in the summer.

And among the people, because of the war in the last years of the Song Dynasty, the method of saltpeter ice was lost, after all, this is an era when there is no Internet and paper books are relatively easy to disperse, coupled with the concept of people's self-cherishing broom, even if someone still knows the method of saltpeter ice, it will not be passed on everywhere, but will be treasured by themselves.

Therefore, this also leads to the fact that the vast majority of people in Daqi today, especially the ordinary people living at the bottom, do not know that saltpeter can be used to make ice.

Not to mention ordinary people, even Xue Mu, a former nobleman, doesn't know it.

After listening to Xue Wan's explanation, she was very surprised, "Sister-in-law, how do you know this?" ”

Xue Wu took out Ye Diao as a shield without changing her face, "This is what the young owner of the Ye family told me." ”

I have heard of the Ye family's Xue Mu, and the Ye family, as an imperial businessman, must be well-informed and well-informed, and it is reasonable to know the method of making ice from saltpeter.

It's just that how can people tell their daughter-in-law?

Looking at her daughter's beautiful little face, she suddenly panicked, so shouldn't the young owner of the Ye family have any bad thoughts about her daughter-in-law?

It's just that in front of her youngest daughter and "son-in-law", Xue's mother can't ask too bluntly, so she can only press the worry in her heart, and prepare to find another opportunity to ask when she goes back.

Because of the hidden worries in her heart, Xue Mu felt that the watermelon in her mouth tasted bad.

Where did Xue Wu think that Xue Mu would actually want to go to that place, and she was still playing with Pei Lian.

"Is watermelon sweet?"

She ate the one on the plate and looked at what Pei Lin was holding.

"Sweet." Pei Lin dug a spoonful and fed it to her mouth.

Xue Wu took a bite and opened her mouth to eat the watermelon.

After eating the watermelon, the sun in the sky also set a little, and the temperature was not so strong, Xue Wu joined the team of picking peppers.

Mother Xue put on her gloves and helped her tie the strap of the hat, "Okay, let's go." ”

Xue Wu tied a bamboo basket around her waist, picked the chili pepper and put it in, at first she felt quite easy, but no matter how simple the work is, once it is done for a long time, it will also hurt her back.

Fortunately, her physical fitness is different now, and she stands up straight and rests for a while, and she is full of energy again.

In the evening, Xue Yao got out of school and rushed over to help pick peppers.

Xue Wu went home to cook first.

She makes knife-cut noodles, and it takes a lot of effort to knead the dough and wake up the dough, so she prepares all kinds of toppings when she is awake.

Shredded mushroom pork, spicy chicken, fried eggs, chili sauce, small green vegetables, fried crispy soybeans, and all kinds of ingredients are on the table.

When Xue Mu and the others came back, they saw all kinds of toppings and seasonings on the table, and they were already very busy, and their saliva was even more watery now.

Xue Wu said: "Wait a while, the noodles will be fine immediately." ”

Holding the dough on her arm, she held a kitchen knife in her right hand, and peeled off the thin dough, which fell into the pot of boiling water in front of her, constantly rising and falling.

After a while, a large bowl of knife-cut noodles was cooked, and Xue Wu beckoned: "Come, bring it out." ”

Bowl after bowl, the last family each held a large bowl of knife-cut noodles, poured their favorite toppings, and then covered it with a fried egg and a few green vegetables, and they all came to life.

If you like spicy, you can add a spoonful of chili.

There was a bucket of water in each corner of the house, and saltpeter was placed in the water, and the frozen water released wisps of cool air, which dispersed a lot of heat in the house.

Rao was like this, and the family at the table was still sweating from eating.

Xue Yao, Xue Mu and Xue Jun are enough to eat a sea bowl, but Pei Lin and Xue Yao, one is an adult man's appetite, and a sea bowl is not enough at all, Xue Yao is the king of big stomachs, and a sea bowl can only cushion the stomach.

So Xue Yao went to the kitchen to shave noodles for the two of them, Pei Lin ate three bowls before stopping, and Xue Yao ate five bowls!

Xue Wu now has a clear understanding of her brother's amount of food, so she is not surprised, and the dough prepared is enough, which can definitely make him full.

Watching him gulp down the noodles, Xue Wu couldn't help but think of the little girl Ah Man, who was only harvested two days ago, the little girl looked quite normal, but she was also very edible.

She thought that if the two of them got together one day, they would have to eat more than anyone else.

That scene must have been exciting.

At the same time, in the city, the Zhao Mansion.

When it was time for dinner, Ah Man never saw the girl come out of the house, and couldn't help shouting twice: "Girl? Girl? ”

I shouted several times, but I didn't hear any sound from inside.

Ah Man was in a hurry, thinking that the girl wouldn't have an accident in the house, right?

However, thinking of the girl's previous instructions, no one was allowed to enter her house without her permission, and Ah Man didn't dare to break in directly, so he could only run and call the housekeeper over.

Chen Tian hurried over and shouted twice, but he didn't get a response, so he simply pushed the door in, and the room was empty.

"Where's the girl?" Ah Man was dumbfounded.

Chen Tian found the note pressed by the teacup on the table, and after reading it, his heart was relieved, it turned out that the girl was not in an accident, but left by herself.

Ah Man was illiterate, so he hurriedly asked, "What is written on it?" ”

Chen Tian said Xue Wu's message.

Aman's eyes lit up suddenly, "I felt that the girl was not an ordinary person, but I didn't expect it to be true, I had been guarding outside the house, but the girl left quietly, I didn't notice it at all!" Butler, do you think the girl is the kind of woman who flies around? ”

Chen Tian couldn't laugh or cry, his first reaction when he saw the note was that the girl might have been kidnapped by the gangsters, but he didn't expect Ah Man to think so.

I have to say that young people are imaginative, but her guess is not unreasonable.

Now we can only wait and see if the girl will come back.

Otherwise, he would have to go to the government to report the case.
