"Xiao Si is right, I have been to many places where there is a lot of snow in winter, and some of those places will send their cars out early in the morning to sprinkle salt on the road, so that by the morning rush hour, the citizens' cars can drive safely on the roads that are already free of snow. ”

Lévy often travels the world to earn extra money to support his family. Although he is far from being as busy as Ma Fanliang's Longdao, he has been to many places around the world over the years. If you have a dream of traveling the world one day, you can ask Levi for advice on directions, accommodation arrangements, and more.

"What the teacher is talking about is actually industrial salt used as a deicing agent. ”

Although she felt very guilty, Miyuki still didn't forget her 'own job' and began to explain Koji's problems to everyone.

"There are two main types of snow melting agents that are commonly used today. One is potassium acetate as the main ingredient, which has good effect and no corrosion damage, but due to the high price, it will generally only be used in important facilities such as airports. The other more common one is chloride salt, the most common of which is the industrial salt-based one. The cost of this deicing agent is very low, and the price is less than one-tenth of the previous one. However, this snow melting agent is very corrosive to public facilities, especially vegetation and crops. For example, if you use too much in the winter near the farmland, the soil will become alkalized, and you will not be able to grow crops even in the spring. It had to be completely replaced. ”

"Oh, it's so harmful, and even if we have enough salt, we can't use it here. How guilty it would be to hurt the plants in the woods next to you. ”

This party found a reason to comfort himself a little from Miyuki's words. But it's just a little comfort. After all, things are already halfway done, and there is no way to recover the losses that have been caused by finding reasons why they can't continue at this time. However, Miyuki actually resembles Koji in many places in her daily life. The two of them are the same natural in many things, for example, now Miyuki doesn't know what this party thinks at all, and even this little comfort is better than nothing is left to her.

"Not really. Only long-term heavy use will alkalize the soil, and we will only do it once in a while, and it will not have a significant impact on the land. In particular, crops that require high soil conditions are not grown here. Plants that are commonly found in the wild are inherently very viable, and they do not wither at the slightest hint of salt. ”

Stare at...... This party raised his eyebrows and stared at Mei Xing, who didn't give face at all. However, many times the natural degree can also be matched with Xiao Si's good luck, but I don't know why this party looks at him like that. She tilted her head and couldn't think of a reason, her head seemed to be full of question marks.

"Well, since Miyuki said that it won't cause damage to the environment, then...... Back to the original question, where are we going to get that much salt?"

The question of how much it costs to buy that much salt has been selectively ignored by this side. Anyway, she didn't think that there was a way to get so much salt in a short period of time in this deep mountain and old forest. Even the resorts of the ski resorts and the hot spring inns where they stay must have channels for regularly purchasing various ingredients and daily necessities from the outside world, and it may be a large supplier from outside that takes the initiative. But even if the supply truck came every day, if they went to the hotel or the ski resort to ask them to order more salt, they would have to deliver it here at least tomorrow, right? In fact, with the 'information' obtained intermittently through various two-dimensional works, it is impossible to purchase daily necessities in remote areas like this, and it is impossible to make a simple phone call to say it, and it will be delivered on time tomorrow.

"It's still impossible to get so much salt now. ”

Although Xiao Jing likes to quarrel with this party, and now she is a little tired of this party's seemingly self-defeating reaction. But the facts are in front of her and she can't ignore them. Although you can continue to try as you did just now, after all, if you insist on saying that the efforts just now have no results at all, it seems that it is not very rigorous. Anyway, the contents of that bucket are not in the same state as when they were first put in, and the surface is indeed solidified, isn't it?

But reason tells Xiaojing that even if he keeps working hard as he just did, he will eventually succeed in making ice cream that his classmates can taste together. The amount of time it takes is quite staggering.

It's good for everyone to travel and try to make a special memory in a special way. However, this particular method will consume all the time of the whole trip, and the final result will not be very dazzling. This particular way is no longer a game, but more like a boring job.

Xiao Jing didn't want to let herself remember this rare long trip in the future, and her mind was full of memories of being like a poor black slave in the seventeenth century. It was as if they had been driven to a big ship, sent to far South America, far from Africa, and then forced by their slave owners to repeat the hard and boring work on the plantations day after day.

"You don't have to have that much salt, do you?"

Levi, who had been watching the girls discuss, actually felt that the direction of their way was a bit problematic. He felt that if he didn't open his mouth to correct it, the group of girls would seem to be less and less interested, and simply give up this 'experiment' that had been worked hard for at the beginning.

If they really gave up, Levi didn't feel sorry for the money that was probably mainly the milk, eggs and other ingredients that the three magical girls bought out of their pockets. But as a teacher, Levi sees the need to teach his students not to waste food, and not to waste food as toys because of half-play. You must know that these seemingly ordinary milk eggs are ...... for those countries in war and poverty Well, Lévy, although he usually meets from time to time, will donate some money to various charities to show sympathy for the poor people in this world who don't know what happiness is. But at the end of the day, Levy is still an ordinary and somewhat selfish mortal who only values the people around him, and does not like to meddle in things, and does not have the heart of the Virgin.
