Su Ran nodded and said: "It's not bad, our county is a relatively large county compared with counties all over the country, and the transportation in our county is quite convenient, whether it is by land or water, it is very convenient!" ”

Liu Yun was taken aback when he heard Su Ran's words, and then asked Su Ran and said, "What, is there still a waterway in our county?" ”

Su Ran nodded and said: "Of course, there are several wharves in our county, and generally if you transport things, it is convenient to transport them by boat, which saves a lot of time compared to land transportation!" ”

Liu Yun was secretly happy after hearing this, if this is the case, then can the tofu he made himself be shipped to all parts of the country.

But Liu Yun just thought about it, knowing that this was impossible, because the shelf life of this tofu was not long, and the transportation in ancient times was not very developed, so if you want to transport it for a long time, it is simply impossible.

After Liu Yun thought about it, he sighed, if he wanted to promote this tofu, it seemed that he could only make the kind of tofu that could be stored for a longer time.

When Su Ran saw Liu Yun and listened to his words, he frowned for a while, and felt a little helpless for a while.

Su Ran felt very curious, and then asked Liu Yun and said, "Why Xiaoyun, how do I feel, you seem to be a little unhappy!" ”

Liu Yun nodded and said, "No, what about being unhappy?" Su Ran, I'm thinking about things! ”

When Su Ran heard Liu Yun's words, saying that he was thinking about things, Su Ran felt strange, "Xiaoyun, are you thinking about things, what are you thinking about?" ”

For Su Ran, of course, Liu Yun had nothing to hide, and then Liu Yun told Su Ran what he thought in his heart.

"That's the case, Su Ran, since we want to make tofu in the future, then I also hope to make our tofu bigger, and then promote it to various places, at the beginning I heard you say that there is water transportation in our county, which is very convenient, I just started to listen to it, I am still very happy, I think that there is this transportation convenience, want to promote the tofu, it is also very easy, but in the end I thought of our tofu, the shelf life of our tofu is not so long, and it is all to eat fresh, Especially in the summer, it may not be able to be stored for two days, so I feel that if we want to transport this tofu to all parts of the country, I don't think it will be possible! ”

After Su Ran heard Liu Yun's words, he also felt that this was a problem, "Xiaoyun, you are not wrong at all, if this tofu is left for a long time, it is indeed not fresh, and the taste is not good, so it is very difficult to promote it in other places, but we can't find a way!" ”

After Liu Yun heard Su Ran's words, he smiled, "Think of a way, what can we think of, this thing of tofu is not a rare thing, if we make this cost high, we won't be able to make any money at all, okay, forget it, Su Ran, let's not think about it so much first, in fact, I am thinking in my heart, we just need to promote this tofu to this county, it is good, and when our tofu goes out, those who want our tofu will naturally come to the door. At that time, we don't need to have a headache for these aspects of transportation! ”

After Su Ran heard Liu Yun's words, he felt that Liu Yun was also very good, "Xiaoyun, in fact, if you want to transport tofu, it's not impossible!" ”

After Liu Yun heard Su Ran's words, he became interested, "Oh, it's not impossible to transport tofu, then you tell me, how should you transport it!" ”

Su Ran listened to Liu Yun's words, smiled mysteriously and said: "We can put a lot of ice cubes in the winter, and when we transport the tofu, we will put the tofu and the ice cubes together, so that even if it is summer, we can't let the tofu spoil quickly!" ”

After Liu Yun heard Su Ran's words, he was shocked in his heart, right, why didn't he think of it? In fact, if you want to keep this tofu fresh, you can also put it together with ice cubes, you really are, and your head melon seeds didn't turn around all of a sudden.

That Su Ran saw Liu Yun's appearance, and then smiled again and said, "Xiaoyun, the idea I had just now was just talking, I know it's impossible to achieve!" ”

After Liu Yun heard Su Ran's words, he felt very strange and said, "Su Ran, why can't it be realized!" ”

Su Ran sighed and said to Xiaoyun: "Xiaoyun, you also know that ice cubes are very rare, everyone wants ice cubes, and they also dig an ice cellar, and then store those ice in the ice cellar in winter, and then they can take it out and use it in summer, these things, generally only large families can afford to use them, and ordinary people don't even think about it, so what I just said is just thinking about it, just laughing, this transportation cost is so high, no one can afford it!" ”

But Liu Yun took Su Ran's words to heart, and said to Su Ran: "Su Ran, who said that this ice can only be stored in winter!" ”

When Su Ran heard Liu Yun's words, he looked at Liu Yun in surprise and said, "Xiaoyun, originally this ice will only have ice when it freezes when it is cold in winter, don't tell me, there will be ice in this summer!" ”

When Liu Yun heard Su Ran's words, he laughed out loud, and then said to Su Ran: "Su Ran has many different substances in this world, and if they meet together, they can produce another substance!" ”

Liu Yun was really reminded by Su Ran just now, and then he remembered, yes, ice may be very difficult to find in ancient times, Su Ran is not wrong, only in winter, everyone puts the frozen ice, and then puts it in the ice cellar, and takes it out for use in summer, the cost is very high, and under normal circumstances, only large families can afford it.

Like those ordinary people, how can they use ice?

But Liu Yun is different, who said that Liu Yun is not this real ancient person? Who is Liu Yun, who is a top student in the 21st century?

As for how ice is produced, when I was in school before, I studied chemistry very clearly, so Liu Yun knew how ice was formed, so if he wanted to make ice, it was not difficult for Liu Yun at all.

I saw Liu Yun smile at Su Ran and said, "Su Ran, Su Ran, you really did me a great favor." ”
