Han Yi, who was already "unbearable", said on the spot: His Royal Highness the Crown Prince is tolerant, my lord is under the rule of Shan Yu, the territory is vast, and naturally there is something that the Han family has nothing to do."

After that, Han Yi asked his entourage to take out a long box, and from this box, took out a white flower, and let Liu Rong look at it.

What Han Yi asked Liu Rong to watch, Liu Rong had naturally seen it, and it was something that originated in the third brother, but it was developed in China first - cotton!

The time when cotton was introduced to China was indeed in the Western Han Dynasty, and it was originally recognized as an ornamental plant, and no one has been able to discover its value.

However, even if Liu Rong knew this cotton, of course he still had to pretend not to know.

Seeing Liu Rong frowning, he asked Han Yi, "Your envoy?" What is this?? ”。

Seeing that Liu Rong didn't know what it was, Han Yi's conceit instantly exploded.

He was very disdainful in his heart, and said secretly: What else did Shicai say, your Han family included the things in the world, and just took out a thing, so I don't know what it is.

Han Yi immediately smiled and said: "His Royal Highness the Crown Prince doesn't know, the name of this thing is called: Bai Diezi, it is a thing produced by my Great Huns, although this flower is broken, it will not wither."

Of course, Liu Rong knows that this Han Yi is full of nonsense, cotton is native to the third brother, and the current name should be called body poison, which is alone in the valley of body poison.

According to historical records, as early as more than 3,000 years ago, the remains of cotton fabrics and cotton threads were found in the ancient tombs of the body poison, and in the Buddhist scriptures before 3,500 BC and 2,800 BC, there were written records of weaving cloth and cotton. Cotton was introduced in the Mesopotamian plains in 1500 BC.

How could it appear in the territory of the Xiongnu at this time.

He was able to get this thing, and it was thought that it was also something that Han Yi got from elsewhere.

However, others don't know the use of this cotton, but Liu Rong knows it very well.

Its biggest role, of course, is not for ornamentation, but for weaving, the people of the Han family today can not afford to use any silk, and the clothes and quilts used in ordinary wear are all made of hemp.

Compared with silk, cotton is the biggest special thing is that its requirements for the length of the environment are not harsh, it can grow in the south, in the northwest desert, can also grow, and its yield is relatively large, so if you can plant this cotton in large quantities in my Han family, and try to weave it into cloth..................

As for how to weave cotton into cloth, the method can be slowly experimented, and the most important thing now is to fool this cotton from Han Yi's hands.

Glancing at Han Yi who was smiling on the side, Liu Rong said bluntly: "I wonder if your envoy can give this white stack to Lonely?" ”。

Han Yi never thought that the prince of the Han Dynasty would ask for it directly.

However, this white stack can only be used as an ornamental plant at most.

What kind of people are the Huns, they are typically egoists and firm, in their opinion, this white stack, of course, is not comparable to the five hundred brocades given by Liu Rong.

Immediately, Han Yi was very reluctant to say: "Since His Royal Highness the Crown Prince wants this thing, then the foreign minister will give this thing to His Royal Highness the Prince."

……………………………………………………………………

Regarding the matter of alfalfa grass, Liu Rong naturally couldn't ask directly, but he continued with Han Yi, and the topic just now was discussed.

"This white stack is indeed something that my Han family does not have, but it can only be viewed, neither used nor edible.

Compared with the silk, salt and other things produced by my Han Dynasty, it is still much inferior."

Liu Rong said this, this Han Yi is really difficult to refute, and it is true that this thing is indeed incomparable compared to silk.

And then Liu Rong smiled indifferently, and ordered a eunuch to present something, which made Han Yi look at it.

Of course, Han Yi didn't know what was in the tray in front of him.

Liu Rong said mysteriously: "This thing is called rhubarb, the best laxative, for all constipation caused by meat poisoning and typhoid fever has a miraculous effect, it can cure diseases caused by food."

Hearing this, Han Yidang stood up excitedly, "Is His Royal Highness the Crown Prince serious?" ”。

"What you say is true!"

…………………………………………………………………………

I have long known that there are some essential differences between the Huns, who are a famous tribe of the grassland, and the Han Dynasty, who are agricultural civilization.

The food of the people of the Han Dynasty was mainly corn and green vegetables, and ordinary people, all year round, it was difficult to eat a few bites of meat, even if it was pork despised by the aristocracy and the elite class, they could not eat it.

The Xiongnu themselves lived a nomadic life, and their population was less than one county of the Han Dynasty.

Its main food is naturally beef and mutton, and if people eat meat all year round, they eat meat all day long.

If you eat too much meat, it is naturally not good, and in the long run, of course, you will be constipated.

With the level of civilization of the Huns, if any of them were ill, their first reaction was, of course, not to go to a doctor.

Rather, it is necessary to find a sorcerer and let the sorcerer pray for the sick person.

Pray for the blessing of their great Kunlun god.

Among the Xiongnu nobles, constipation has led to the death of many people.

Solidly, in the eyes of the Huns, everything that can solve constipation is a fetish!

Rhubarb is an important laxative, heat-clearing and hemostatic medicine. It has a rapid effect and is often used in critical and severe cases. In the Eastern Han Dynasty, Zhang Zhongjing's prescriptions used rhubarb in 32 poems, including Daxiao Chengqi Soup, Dachaihu Soup, Sanhuang Xingxin Soup, Taohe Chengqi Soup, etc., which are still widely used in clinical practice.

However, some famous doctors in history are good at using rhubarb, and his real name and surname have been forgotten, and he is only known to be good at using rhubarb, such as Mu rhubarb in the Jin Dynasty.

Of course, for Liu Rong, the biggest regret is that in modern times, he did not study medicine, let alone Chinese medicine.

If Liu Rong is a medical student, he can take a few prescriptions casually, and he can use them greatly.

However, after the Han Dynasty came, Liu Rong knew that the Han family before the Western Yuan Dynasty had no prescription that could be used.

If Liu Rong is a medical student, he can take a few prescriptions casually, and he can use them greatly.

After the opening of the Silk Road, not only the silk and spices of China were affected by foreign countries, but its obsession with rhubarb was even more unimaginable.

Europeans have a tradition of eating rhubarb, and before the local edible rhubarb was cultivated, medicinal rhubarb was imported from China for more than a decade, longer than the tea trade.

At the time of the Han family, tea was a function, and it was not used for daily use, but most of the time it was used for medicinal purposes.

In the era of ancient legends, Shennong tasted herbs, boiled and drank raw leaves, and used tea for medicinal purposes.

By the time of the Qin and Han dynasties, although it had begun to be used as tea, cooking, and soup.

But in the tea brewed by the Han family, a large number of other condiments are generally added.

The taste was really unacceptable, and after drinking it once, Liu Rong never wanted to have a second experience.

Rhubarb and tea were exported in such large quantities that in the Qing Dynasty after the rise of the tea trade, people even thought that Europeans would die of constipation and bloating without rhubarb and tea from China.

There is also a saying that the Opium and Chip Wars can also be called the Rhubarb War, the sweaters consumed too much silver to import rhubarb and tea from China, and when they resold the silver plundered from the colonies to China, the trade deficit was inevitable, so they turned to dump opium and chips in China, and then started a war.

However, the history of European consumption of rhubarb can be traced back to the Han Dynasty, since Zhang Qian hollowed out the Western Regions, the Han Dynasty government took control of the Hexi Corridor, and the merchants on the Silk Road were busy, transporting spices, precious stones, gold, furs, wool fabrics from Central and West Asia to the East, and silk, porcelain and medicines from China to Persia.

Caravans of all kinds crossed Asia Minor to Turkey, crossed the Bosphorus Strait into Europe by boat, and of course, the unknown Europeans eventually called the rhubarb from Turkey Turkish rhubarb.

After the Song Dynasty, the Southern Silk Road and the Maritime Silk Road arose, China's goods raw silk, silk, porcelain, medicines, etc. were transported by merchant ships to Malaysia and then to India, and then from India to Europe.

Then Han Yi couldn't wait to say, "His Royal Highness the Prince, can you allow your ministers to give it a try?" ”。

Liu Rong immediately stretched out his hand and said, "Naturally, your envoy will please."

After Liu Rong finished speaking, Han Yi immediately summoned someone in Xiongnu language and said something.

When the prince came to see the Huns, he naturally had to make complete preparations.

Solid for this, after Daxing ordered Zhang Feng to learn the news, of course, he sent an interpreter at the first time.

Han Yi and another person said there, and this translator originally thought that if he came to the palace today and behaved well, maybe he would be remembered by His Royal Highness the Prince, and there might be a possibility of promotion in the future, but since His Royal Highness the Crown Prince saw this Hun envoy, he was dumbfounded.

The two of them communicated in Chinese throughout the whole process, and the Han dialect of the Xiongnu was simply the same as that of the Han people.

However, now, seeing that it was finally time to use himself, he immediately came to Liu Rong's approach.

He saluted and said: "His Royal Highness the Prince, the Hun envoy is saying ............."

Han Yi and the Huns muttered for a while, but this translator translated the conversation between the two and informed Liu Rong of the whole process.

After speaking, the Huns stepped forward, picked up the rhubarb from the tray, broke off a piece, and put it in his mouth.

However, after eating, it didn't take long for this person to salute Han Yi, and he covered his stomach to go out of the Qilin Palace......

And Han Yi, when he saw the scene in front of him, he was dumbfounded, this thing called rhubarb was so easy to use.
