Su Ran nodded and said: "Not bad, our county is a relatively large county compared with other counties across the country, and the transportation in our county is quite convenient, whether it is land or water, it is very convenient.

!”

Liu Yun was shocked when he heard Su Ran's words, and then asked Su Ran: "Why, are there waterways in our county?"

Su Ran nodded and said: "Of course, there are several docks in our county. Generally, when everyone transports things, it is more convenient to transport things by ship. It saves a lot of time than transporting by land!"

After hearing this, Liu Yun was secretly happy. If this was the case, then the tofu he made could be shipped to all parts of the country.

But Liu Yun just thought about it and knew that this was impossible, because the shelf life of this tofu was not very long, and transportation in ancient times was not very developed, so long-term transportation was simply impossible.

things.

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

When Su Ran saw Liu Yun, after hearing what she said, she frowned for a while, and then felt a little helpless.

Su Ran felt very curious, and then asked Liu Yun: "Why Xiaoyun, why do I feel that you seem a little unhappy?"

Liu Yun nodded and said, "No, are you unhappy? Su Ran, I'm just thinking about something!"

Su Ran heard Liu Yun's words and said that he was thinking about something. Su Ran felt strange, "Xiaoyun, you are thinking about something, what are you thinking about?"

Of course, Liu Yun had nothing to hide from Su Ran, and then Liu Yun told Su Ran what he was thinking.

"It's like this, Su Ran, if we want to make tofu in the future, then I also hope to make our tofu bigger and spread it to various places. At first, I heard you say that our county has water transportation, which is very

Convenient. After I first heard about it, I was very happy. I thought it would be convenient to transport tofu and I would like to promote tofu.

It’s quite easy to go, but in the end I thought about our tofu. The shelf life of our tofu is not that long, and it must be eaten fresh. Especially in the summer, it may not be preserved for two days.

, So, I feel that if we want to transport this tofu to all parts of the country, it will be impossible!"

After Su Ran heard Liu Yun's words, she also felt that this was a problem, "Xiaoyun, you are absolutely right. If this tofu has been stored for a long time, it will indeed become stale and taste bad, so I want to go somewhere else."

Local promotion is also very difficult, but it’s not impossible for us to find a way!”

After Liu Yun heard what Su Ran said, he smiled and said, "Let's think of a way. What can we think of? Tofu is not a rare thing. If we increase the cost, we won't be able to make any money at all.

What kind of money? Okay, forget it, Su Ran, let’s not think about it so much first.

Actually, I am thinking in my heart, we just need to promote this tofu to this county, which is good. When our tofu becomes famous, those who want our tofu will naturally come to our door.

Then we won’t need to worry about these aspects of transportation!”

After Su Ran heard Liu Yun's words, she felt that Liu Yun's words were very good, "Xiao Yun, actually it is not impossible to transport tofu!"

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

After listening to Liu Yun's words, Su Ran smiled mysteriously and said: "We can put a lot of ice cubes in winter, and then when we transport tofu, we will put the tofu and ice cubes together. In this case, it will not be possible even in summer.

Let that tofu go bad quickly!”

After Liu Yun heard Su Ran's words, he was shocked. Yes, why didn't he think of it? In fact, if you want to keep this tofu fresh, you can also put it with ice cubes. He really is a melon in the head.

There was no turning around at once.

When Su Ran saw Liu Yun's look, he smiled and said, "Xiaoyun, what I just thought was just talk. I know it's impossible to realize!"

After Liu Yun heard what Su Ran said, 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. If everyone wants ice cubes, they dig an ice cellar, and then put them in during winter.

The ice is stored in the ice cellar and can only be taken out in the summer

Generally, only wealthy families can afford these things. Ordinary people don't even think about it. So, what I just said is just a thought and a joke. The 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 this ice can only be stored in winter!"

When Su Ran heard Liu Yun's words, she looked at Liu Yun in surprise and said, "Xiao Yun, originally this ice only exists when it freezes in the cold winter. Don't tell me that it will also freeze in this summer."

There will be ice!”

When Liu Yun heard Su Ran's words, he burst out laughing, and then said to Su Ran: "Su Ran, there are many different substances in all things in the world. When they come together, they can be transformed into another kind of 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 was right, only in winter, everyone would

The cost of freezing ice is very high, and then it is placed in an ice cellar and used in summer. Generally, only wealthy families can afford it.

How can ordinary people make ice?

But Liu Yun is different. Who says Liu Yun is not a truly ancient person? Who says Liu Yun is a top scholar in the 21st century?

As for how ice is produced, those who studied chemistry in school are very clear about it, so Liu Yun knows how ice is formed, so making ice is not difficult for Liu Yun at all.

I saw Liu Yun smiling at Su Ran and saying, "Su Ran, Su Ran, you really did me a big favor."
