As the leader of the Ministry of Works, Wei Yan enjoys the largest and most luxurious room in the Ministry of Works for office use.

Private carriages cannot enter the yamen. Wei Xi got off the carriage outside the gate of the Ministry of Works and was led all the way in by his father's servant. The officials coming and going in the Ministry of Works saw that the servants brought by Lord Shangshu led a young girl in. Before he could take a closer look, he almost guessed the identity of the visitor, so he hurriedly avoided him.

Wei Xi was unobstructed all the way and was taken to Wei Yan by the servant.

Seeing his little daughter stepping into the door, Wei Yan hurriedly poured the last bite of soup from the bowl, "Why did Xier come to the Ministry of Works to find her father?"

Wei Xi was blessed with a blessed body. When he looked up, he saw Wei Yan's eye-catching dark circles hanging on his face with big thorns, his eyes full of red bloodshots, "Did Daddy haven't been asleep all night?"

Wei Yan coughed lightly, "I have been a little busy lately. When the work is over, my father will have a good rest."

The servant quietly stepped out when he saw the master who was neatly accused of his mistakes.

"Xiao Qi, bring the map."

Before Wei Yan could ask Wei Xi what he had done with the map, he saw the map that was painted densely and could hardly see its original appearance.

Wei Yan: "······"

Xiaoqi had already spread the map on the desktop as he said.

Wei Xi walked to the table and reached out and clicked the map, "Daughter doesn't waste Dad's time, just say a few words. I guess Dad is busy with two things recently. One is how to quickly clear out the snow that hinders the bridges of the North Road, but how to quickly build a house for disaster victims to live in."

When Wei Yan heard Wei Xi say this, he knew that his youngest daughter was not just here to care about him, but to tell her something serious. She couldn't help but become serious and nodded, "That's right."

Outside the door.

The servant saw Zong Xu walking over and was about to salute him, but the other party raised his hand to stop him.

Then he saw His Highness, King Yue, who did not turn around and leave, nor knock on the door, but stood at the door and stopped moving, and even turned his ears slightly.

The servant: "·······"

The father and daughter in the room did not notice that there was someone standing outside, so Xiaoqi noticed it. However, since the master and servant who were guarding outside did not make a sound, she thought about it and did not remind her.

Wei Xi said ignorantly and then said, "My daughter came up with two solutions last night. But before my father returned home, I knew I had come to find my father."

She said as she reached out to the bay that was highlighted on the map, "Look at this place, Daddy."

Wei Yan looked down and said, "This is a bay, which is very shaped, but there is no town around, so I'm afraid it's sparsely populated. So, is Xier showing this bay to Daddy, what's the purpose?"

He would ask this because he knew that his little daughter would never be aimless.

So, what's special about this bay?

"The bay should have rich seafood, but it is uninhabited here. My daughter guessed that the reason is that the sea water in this bay is a bit special. This bay is likely to be a salt sea."

"Salt Sea?"

Wei Xi nodded, "Dad, it's the salt we eat. You also know that there is a lot of salt in the sea water, but there are also some lakes and sea water. If the amount of salt is too much, it is also not suitable for the survival of fish and shellfish in the sea."

Wei Yan thought, "This is the reason. People cannot eat too much salt, so the same is true for fish, shrimps, etc."

Wei Xi: "········Yes."

"But, what does this have to do with cleaning up snow and building a house?"

Wei Xi asked back: "How did Dad originally plan to clean up the snow?"

"One is to gather people to shovel the snow to the side of the road, and secondly, to burn fire along the way to melt the snow."

Wei Xi said to himself.

The value of salt is so high, who would have thought of using it to melt snow? Even if someone thinks of it, he may not be willing to bear it.

"The way my daughter thought of was to use salt to melt the snow."

"Salt?" Wei Yan's eyes widened at first, and then reacted, "This is why Xier, you told me about this bay? But how does this salt melt the snow?"

Wei Xi: "If dad doesn't believe it, you'll know it just a try."

Wei Yan was really curious at this time, and the officials in the yamen did not come to report the matter, so he thought about going to the yard to experiment.

As soon as he called the servant outside, he heard that the door was knocked.

Wei Yan: "······Please come in."

Zong Xu pushed open the door and bowed to Wei Yan first, "Master Wei." He looked at Wei Xi again, "Xi Xi."

Wei Yan coughed lightly, "I have seen His Highness the King of Yue."

Wei Xi followed her father and also became blessed with good manners, "I have met His Highness the King of Yue."

Zong Xu was frank, "I just heard the conversation between Lord Wei and Xixi outside the door. I wonder if I can see with my own eyes how the salt melts snow?"

Wei Xi couldn't help but look up at him when he heard this.

What else could Wei Yan say? Naturally, he nodded.

The work department also has a kitchen. The servant went there to ask for a pack of salt. When he passed by the base of the wall of the house, he shoveled a few shovels of blood back.

It's just the sun shining today.

The servant divided the snow into two piles of similar sizes. He was about to spread salt on the smaller snow pile, but Wei Xi stopped him, "Spray the bigger snow pile."

The servant had to do as he said.

The salt particles rustled down, and several pairs of eyes fell on the two snow piles in front of them.

Time passed slowly, and soon they saw that the two snow piles had obvious changes.

The snow pile that did not sprinkle salt was indeed smaller than the moment, but the snow pile that sprinkled with eyes was half smaller, and there was a pool of salt water on the ground.

When the salt-spreaded snow pile completely melted, there were more than half of the snow pile next to it.

Wei Yan and his eyes could no longer help but shiny. "This salt can really make the snow melt quickly," he said, looking at Wei Xi, who looked unsurprising. "How did Xier think that this salt can melt the snow?"

When he asked, several pairs of curious eyes looked over. Wei Xi pointed his chin with his fingers, "Actually, it is related to a characteristic of salt. We all know that if a person wears sweaty clothes, the clothes will be easily wet. This is because people have salt in their sweat, and the salt absorbs water. When they sprinkle the salt grains on this snow pile, the outermost snow is first melted into water by the sun, and when it melts with salt, it becomes salt water. I also conducted an experiment, putting water and salt water in the same cold place. Over the past night, the water would condense into ice, but the salt water is still salt water, which means that it is difficult for salt water to freeze."

Wei Xi said and pointed to another snow pile that was still melting slowly, "In fact, the snow is constantly melting and condensed into snow. This is why the snow in the shade has not melted yet after so many days. Its melting speed is the same as the speed of condensed into snow. But after the snow turns into salt water, it is different. The salt water can no longer ice, and the remaining snow is also eroded by salt water, so naturally it will melt into salt water soon."

Wei Xi explained carefully, not only Wei Yan and Zong Xu, but also Xiaoqi and the servant beside him understood.

The four of them nodded in a sudden realization.

Zong Xu took the lead in speaking, "Since it is effective to use salt to melt snow, I will send someone to that bay to check whether it is really the salt sea that Xixi mentioned."

If so, he would try his best to spread the sea water to the north.

After all, the four words he has always believed in are things that are caused by humans.

Wei Yan had just started to worry about who to send to do this matter. When he heard Zong Xu say this, he immediately bowed and said, "Then you will be the best of Your Highness, King Yue."

After all, as long as the matter is done by His Highness King Yue, he will feel at ease with one hundred.

"There are also house construction." Seeing his father suddenly turning his head and looking over, Wei Xi couldn't help but curl his lips, "Dad still remembers the glazed greenhouse we built in Hengdu?"

"The one who grows vegetables?" Wei Yan reacted very quickly this time, "Xi'er, what do you mean is to build the glass greenhouse in the north for the purpose of retention of disaster victims?"

Wei Xi nodded, "Dad thinks it's feasible?"

Wei Yan naturally had been to the glass greenhouse. It was snowing heavily outside, but it was as warm as spring inside.

It is certainly possible to use it to live in people.

"But, that Liuli?"

How can there be so many glazed greenhouses to build glazed greenhouses?

He briefly estimated that taking the glazed greenhouse in Hengdu as an example, it would take 300 people to squeeze into one person. Now there are about 50,000 people in the north that are affected by the disaster, so at least nearly 200 buildings will be built, and the amount of glazed glass you want to use is needed.

Wei Yan took a deep breath and shook his head repeatedly: "It's not feasible."

Not to mention that even if there is so much glass, how much money will it cost to buy it?

Although Liulichang belongs to her little daughter, Wei Yan never thought of taking it for nothing.

Wei Xi had long guessed that her father would not agree, so he reached out to grab Wei Yan's sleeve and shook it, "Dad, my daughter can do her best. And before coming to see you this morning, I had already instructed the glazed field in Shangjing City to stop supplying supplies to glazed workshops in various places in Dayong, and only built glazed windows needed for glazed greenhouses. In addition, I also wrote a letter to Hengdu. Although it would be later in Hengdu, I would do this after receiving the letter."

Wei Yan couldn't help but take a breath.

He didn't know how many branches his youngest daughter's glass shop had opened in Dayong, but he had a general understanding of the amount of glass that the two glass shops could produce every day.

If you only build glazed windows, you can almost build ten glazed greenhouses in a day.

That would take twenty days.

"Xi'er, do you know how much money will be lost in your Liulifang?"

Twenty days, not only do you not make money, but you also have to pay money hard.

Even if it were him, he would not have the courage to make this decision for a while.

"I haven't calculated it." Wei Xi shook his head and replied honestly.

Since you have made a decision, you won’t leave any room for regret.

Why bother to calculate how much money you will lose?
