As the head of the Ministry of Industry, Wei Yan enjoys the largest and most luxurious room in the Ministry of Industry for office use.Private carriages are not allowed to enter the yamen, Wei Xi got off the carriage outside the gate of the Ministry of Industry, and was led in by his father's servant.The officials who came and went in the Ministry of Industry saw that the little girl brought in by their Lord Shangshu brought in a young girl, and before they could look closely, they almost guessed the identity of the person who came, and hurriedly turned sideways to avoid it.Wei Xi went all the way unimpeded and was brought to Wei Yan by the little guy.Seeing his little daughter stepping into the door, Wei Yan hurriedly poured the last mouthful of soup in the bowl, "Why did Xi'er come to the Ministry of Industry to find Daddy?"
”Wei Xi blessed his body, and when he looked up, he saw Wei Yan's eye-catching dark circles, big thorns hanging on his face, and his eyes were full of red bloodshots, "Daddy hasn't slept all night?"
”Wei Yan coughed lightly, "I've been busy lately, and when things are done, my father will have a good rest." ”Seeing his neat and innocent master, the little guy quietly retreated."
Xiao Qi, bring me the map."
Before Wei Yan could ask Wei Xi what he was doing with the map, he saw the map that was so densely drawn that he almost couldn't see what it looked like.Wei Yan: "Xiao Qi has already spread the map on the table according to his words.Wei Xi walked to the table and stretched out his hand to click on the map, "My daughter won't delay her father's time, just say a few words."
I guess there should be two things that Daddy has been busy with lately.The first is how to quickly clear the snow that obstructs the roads and bridges on the North Road, and how to quickly build houses for the victims to live in. ”As soon as Wei Yan heard Wei Xi say this, he knew that his little daughter was not just here to care about him this time, but to tell her something serious, and his expression couldn't help but become serious, and nodded, "That's right." ”Outside the door.When the little guy saw Zong Xu coming over, he was about to step forward to salute, but was stopped by the other party who raised his hand first.Then he saw His Royal Highness the King of Yue, did not turn around and leave, nor did he knock on the door to enter, but stood at the door and did not move, and tilted his ears slightly.Xiaowu: "" The father and daughter in the house didn't notice that there was someone standing outside, and Xiao Qi noticed it, but since the old man's little servant who was guarding outside didn't make a sound, she thought about it and didn't open her mouth to remind her.Wei Xi didn't feel it anymore and said: "My daughter came up with two ways last night, but my father didn't return home, so I knew that I came to find my father." ”She said as she reached out a little on the bay that had been highlighted on the map, "Daddy, look here." ”Wei Yan looked down, "This is a bay, and the shape is special, but there is no town around, so I'm afraid it's sparsely populated."
So, is there any purpose for Xi'er to show her father this bay?
”He would ask this because he knew that his little daughter would never be untargeted.So, what's so special about this bay?"
The bay is supposed to be rich in seafood, but it is uninhabited, and my daughter guesses that the reason is that the sea in this bay is a little special.This bay is most likely a salt sea. ”"Salt Sea?"
Wei Xi nodded, "Daddy, it's the salt we eat."
You also know that there is a lot of salt in the seawater, but there are also lakes and seawater that are also not suitable for the survival of fish and shellfish in the sea if they contain too much salt. ”Wei Yan thought thoughtfully, "That's the truth.People can't eat too much salt, and the same goes for fish and shrimp. ”Wei Xi: "Yes. ”"But what does this have to do with clearing snow and building houses?"
Wei Xi asked rhetorically, "How did Daddy originally plan to clear the snow?"
”"One is to gather people to shovel the snow to the side of the road, and the other is to burn fires along the way to melt the snow."
Wei Xi said in his heart, sure enough.The value of salt is so high, who would have thought of using it to melt snow.Even if someone thinks of it, I'm afraid they can't bear it."
My daughter's idea is to melt the snow with salt.""
Salt?"
Wei Yan's eyes widened at first, and then he reacted, "That's why Xi'er told me about this bay?"
But how does this salt melt snow?
”Wei Xi: "If Daddy doesn't believe it, just give it a try." ”Wei Yan was really curious, and the officials in the yamen didn't come to report on the affairs, so he thought about going to the courtyard to try it out.As soon as he called out to the little man outside, he heard a knock on the door.Wei Yan: "Please come in." ”Zong Xu pushed open the door and arched his hand towards Wei Yan first, "Lord Wei." ”looked at Wei Xi again, "Xi Xi." ”Wei Yan coughed lightly, "I've seen His Royal Highness King Yue." ”Wei Xi followed behind her father, and also followed the rules and regulations to bless her body, "I've seen His Royal Highness King Yue." ”Zong Xu was also frank, "Just now I also heard the conversation between Master Wei and Xi Xi outside the door, I wonder if I can also see with my own eyes how this salt melts snow?"
”Wei Xi couldn't help but glance up at him when he heard this.What else could Wei Yan say, he naturally nodded.The ministry also had a kitchen, and the servant went there to ask for a bag of salt, and when he passed by the base of the wall of the shady house, he shoveled a few shovels of blood and came back.It's a sunny day.The little guy divided the snow into two piles of about the same size, and was about to sprinkle the salt on the snowdrift that looked smaller, but Wei Xi stopped him by a voice, "Scatter the larger snowdrift." ”The little guy had no choice but to do as he was told.Grains of salt poured down, and several pairs of eyes fell on the two snowdrifts in front of them.Time passed slowly, and soon they saw that the two snowdrifts had changed significantly.The snowdrift without salt was indeed smaller, but the snowdrift that was sprinkled was already half smaller, and there was already a puddle of salt water on the ground.When the salted snowdrift melts completely, there is still more than half of the snowdrift next to it.Wei Yanhe's eyes couldn't help but light up, "This salt can really make this snow melt quickly," he said and looked at Wei Xi, who didn't look surprised at all, "How did Xi'er think that this salt could melt snow?"
”When he asked, several pairs of curious eyes also followed, Wei Xi tapped his chin with his finger, "In fact, it is related to a characteristic of salt, we all know that if people wear sweaty clothes, the clothes will be easily damp, this is because people's sweat has salt in them, and salt absorbs water."
When the grains of salt are sprinkled on the snowdrift, the outermost layer of snow is melted into water by the sun, and when it melts with the salt, it becomes salt water.I also did an experiment where I put water and salt water in the same cold place, and the water would freeze overnight, but the salt water would still be salt water, which means that salt water is very difficult to freeze. ”Wei Xi said and pointed to another snowdrift that was still slowly melting, "Actually, snow is constantly melting and condensing into snow, which is why the snow in the shade has not melted after so many days, and the speed at which it melts is the same as the speed at which it condenses into snow."
But it is different when the snow turns into salt water, the salt water can no longer freeze, and the remaining snow is also eroded by the salt water, and naturally it will soon melt into salt water. ”Wei Xi explained carefully, not only Wei Yan and Zong Xu, but even Xiao Qi and Xiao Wu on the side also understood.The four of them nodded in unison.Zong Xu was the first to speak, "Since it is effective to use salt to melt snow, then I will immediately send someone to that bay to find out whether it is really the salt sea that Xi Xi said." ”If it was, he would have tried to scatter the sea to the north.After all, the four words he has always believed in are man-made.Wei Yan just began to worry about who to send to handle this matter, and when he heard Zong Xu say this, he immediately arched his hand and said: "Then there is His Royal Highness King Lao Yue." ”After all, as long as the matter is done by His Royal Highness King Yue, he can rest assured."
And the building of houses."
Seeing his father turn his head abruptly, Wei Xi couldn't help but hook his lips, "Daddy, do you remember the glazed greenhouse we built in Hengdu?"
”"The one who grows vegetables?"
Wei Yan reacted quickly this time, "Xi'er, what do you mean by building that glazed greenhouse to the north for the purpose of taking in the victims?"
”Wei Xi nodded, "Does Daddy think it's feasible?"
”Wei Yan had naturally been to the glazed greenhouse, and it was snowing heavily, but it was warm as spring inside.It is also possible to use it for living people."
Just, what about the glass?"
How can there be so much glass to build a glass greenhouse?
He briefly estimated that taking the glazed greenhouse in Hengdu as an example, squeezing one can accommodate 300 people, and the people in the north are now about 50,000 people, so at least nearly 200 will be built, and the number of glazed glass that you want to use.Wei Yan gasped and shook his head repeatedly: "It's not feasible." ”Not to mention that even if there is so much glass, how much silver does it cost to buy?
Although Liulichang is the youngest daughter's, Wei Yan never thought about taking it for nothing.Wei Xi had already guessed that her father would not agree, so she reached out and grabbed Wei Yan's sleeve and shook it, "Dad, my daughter can also do her part."
And before I came to see you this morning, I had already instructed the glaze field in Shangjing City to stop supplying to the glazed workshops in Dayong, and only build the glazed windows needed for the glazed greenhouse, and also wrote a letter to Hengdu, although Hengdu will be late, but after receiving the letter, it will also do. ”Wei Yan couldn't help but gasp.He didn't know how many branches his youngest daughter's glaze workshop had opened in Dayong, but he had a general understanding of the amount of glaze that the two glaze farms could produce every day.If you only build glass windows, you can build almost ten glass greenhouses in one day.That's twenty days."
Xi'er, do you know how much silver your glass workshop will lose in this way?"
For twenty days, not only did he not make money, but he also had to put money into it.Rao is him, and he will not have the courage to make this decision for a while."
I haven't counted."
Wei Xi shook his head and replied honestly.Now that you've made your decision, don't leave yourself room for regret.Why bother to count how much money you will lose?
Wei Yan: "He was convinced of his little daughter again!
