Du He returned to Du Mansion a little tired, and in the past few days, with the assistance of Li Shimin, he met with several naval generals, and wanted to find an experienced naval general to be responsible for the voyage. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

However, it was a big disappointment, the Tang Dynasty was strong in the military, far ahead of the previous dynasty, even if there were millions of war horses in China, when marching, even the foot soldiers could also be assigned to horses to walk, increasing the speed of marching. Such armament, even the Han Dynasty did not have, which shows the strength of the Tang Dynasty's military strength.

However, the focus of the Tang Dynasty was in the Western Regions and Mobei, and there was no idea of conquest in the eastern seas. Individual naval generals still stayed behind when Li Xiaogong marched south to Xiao Milling and Fu Gongyi, and they all became army generals, and they have not been exposed to water warfare for many years.

Du He also knew in his heart that he was too harsh and demanding, and the navigation industry really flourished in the middle of the Tang Dynasty, when the early Tang Dynasty was still groping, it was reasonable that there were no experienced talents, but he knew better how important it was to be an excellent captain when traveling on the sea.

"It seems that you can only go step by step, and if you don't have experience, you can increase from continuous accumulation! He did not want to go to the American continent in one breath and mingle with the Indians, but first opened up a shipping route in the waters of Asia, and then sailed south to the American continent after he was familiar with everything. ”

Come to think of it, this is already the best way to do it.

Du He walked into the mansion, walked to the lobby, and unexpectedly saw two beloved wives discussing around a plate, and then discussing something, even Du He didn't notice when he came in.

"Sister Changle, what is this?" Li Xueyan took a piece of pink fruit on the plate that was cut into a thin layer and almost like apple flesh, and took a bite gently.

"I don't know, I've eaten a lot of fruits, but I've never seen anything like this!" Changle is Li Shimin's most beloved baby daughter, what are the strange things and food, once Li Shimin receives it, the first thing is to let people send some to Changle, even if he is married, this love will not be diminished in the slightest, once he receives strange things from other countries, he will still let people send them to Du Mansion. She has seen a lot of strange things, but the rare fruit in front of her makes her frown lightly, and she can't tell where it comes from.

"What more!" Du He smiled and walked closer, his eyes fell on the plate of fruit that attracted the two beloved wives, stunned, so familiar, the pink flesh seemed to evoke some memories in the depths of his heart.

Changle greeted him with a smile and said: "The rare thing sent by the second girl of the martial arts family, I can't say what it is, but it tastes good, sweet and crunchy, very delicious, Xianggong ...... taste it."

She took a piece of pulp and fed it to Duhe with a smile. They have a deep relationship and have been married for many years, but they don't have any life, and similar things often happen.

Du He's smiling face and posture appeared in his mind, and he said in his heart: "She's back?" Take a time to take a look, I haven't seen you for a long time, I miss it! Facing the pulp handed by Changle, he opened his mouth with a smile, and with a bite of "click", the whole person was completely stunned, and a monstrous wave turned up in his heart, and exclaimed: "This ...... Is this a sweet potato? ”

His mouth opened, and the flesh of his mouth fell to the ground.

"What's wrong? Is this called a sweet potato? Changle looked at Ailang inexplicably, and glanced at Li Xueyan with each other, with a sad look in each other's eyes. His lover has always been calm and calm, and this kind of frightened expression is rare to see.

Du He didn't answer, took two steps forward, grabbed two pieces of pulp, bit carefully, tasted the taste, that feeling was indeed a sweet potato, and it was a high-starch red heart sweet potato.

Sweet potatoes are a common crop in the countryside, Du He ate them in the countryside when he was a child, and ran to the ground to dig a few on holidays, washed them in the ditch and ate them raw, but later returned to the city, and there was no chance to eat them, and occasionally they ate roasted food from roadside vendors.

Now the sweet potatoes on the plate have been peeled and cut into slices, so he only feels familiar, and he didn't expect that the flesh would be a sweet potato until he ate it in his mouth, and the long-lost feeling told him that the flesh was the red sweet potato he often ate in his childhood.

After being stunned for a while, Du He shouted: "Sweet potato, something amazing, Changle, Snow Goose, I'll go find Mei Niang, haha, if you're lucky, your husband is going to make a meritorious deed......"

Before Changle and Snow Goose could react, Du He's figure had disappeared into the lobby, and the sound of Du He's laughter was faintly heard in the distance, for some reason.

Du He's eyes sparkled, and his heart was completely ecstatic about what might happen.

Sweet potato is the name of his old family, people in different regions call it different, Henan people call it sweet potato, Shanghai people and Tianjin people call it sweet potato, Shandong people call it sweet potato, southern Jiangsu calls it sweet potato, Xuzhou region calls it white taro, Shaanxi people call it red taro, Sichuan and Guizhou people call it red potato, Beijing people call it white potato, Jiangxi people call it sweet potato.

Sweet potato is a treasure, its existence has fed tens of millions of Chinese people, and even today some people call the Qing Dynasty the sweet potato dynasty.

This is not unreasonable.

Duho is a history graduate and knows this.

That was in the Wanli years, in the sixth year of Wanli, when Zhang Juzheng took Fujian as a pilot, cleared the acres of fields, registered household registration, and implemented a whip law, the news from this southern province surprised him inexplicably, and was full of sadness: when the national census was conducted in the 26th year of Hongwu, there were more than 810,000 households in Fujian, nearly 4 million people, but after 200 years of "growing teeth", only 510,000 households remained, nearly 1.8 million people.

The sharp shrinkage of the hukou is certainly due to the concealment and concealment of information by the people, but also reflects the embarrassing situation of this province. What is surprising is that more than 200 years later, 14 years after the Qing Daoguang Dynasty, Fujian was still plagued by famine and on the verge of bankruptcy, but its registered population reached an unprecedented 15 million, an increase of more than nine times. At the same time, the number of national hukou has surged by about sevenfold, reaching a staggering 400 million.

The key to this is the humble sweet potato.

History proves this!

In the twenty-first year of Wanli, a man named Chen Zhenlong in the Ming Dynasty introduced a crop called "vermilion potato" from Luzon Island, and four months later, the introduction was successful and the name was changed to sweet potato.

And the following year, southern Fujian was hit by a severe drought. "Zhangzhou Mansion Chronicles" recorded: "The weeds are not green, the grass is not harvested, and the hungry people are everywhere." At that time, Jin Xue, the governor of Fujian, had the opportunity to make a decision and told the counties of southern Fujian to plant sweet potatoes widely. Just a few months later, the sweet potato harvest was abundant, and the hungry people were "full of hunger, and the disaster was not a famine".

In just a few months, the existence of sweet potatoes has solved a famine, which shows the power of sweet potatoes.

Fujian is part of Lingnan, with hills and red soil, and only small plains and basins can be used to grow rice. Not only are the fields narrow and densely populated, but the land is barren and fragmented, and since the promulgation of the "sea ban", there has been famine, famine, insufficient rice production, and depression in people's livelihood...... All kinds of suffering pervade the people, and the annals of history are endless.

But because of the existence of sweet potatoes, famine gradually faded out of Fujian.

The key is that sweet potatoes are coarse and cheap, even if the "land belongs to sandy soil", not to mention hilly land and red soil; It is shallow buried in the soil, which cannot be eroded by wind and rain, and is resistant to drought; The yield is extremely high, about 10,000 catties of one mu of upper land, about 78,000 catties of middle land, and about 5 or 6,000 catties of lower ground...... Such an astonishing constant soon became a symbol of people's livelihood in the province for the next 500 years.

Perhaps because sweet potatoes are too lowly and are not accepted by the Jiangnan region, it has become a big pity.

However, during the Kangxi Dynasty, in order to cut off the supply of southeastern provinces to Taiwan, the Qing government issued an order to move to the sea. In addition to the burning of boats, houses, and rice crops, all coastal residents moved to the mountainous areas of the interior, and "those who violated the law were immediately punished." During the migration that lasted for more than 20 years, tens of millions of refugees were like livestock, their eyes were gray and they walked into the mountains, and hundreds of thousands of people died.

In this kind of disaster life, sweet potatoes have once again become the savior of thousands of victims, and lilac sweet potato flowers symbolizing suffering can be seen everywhere in western Fujian, Jiangxi, Guangxi and even Anhui.

If it is said that during the period of the sea migration, the scenes of "crying and shaking the sky" and dying in the ravines abounded, then another larger-scale and longer-lasting westward migration soon after seemed to contain a faint hope. In the 33rd year of Kangxi's reign, the Qing Shengzu issued the "Edict of Recruiting People to Fill Sichuan", which started the wave of immigrants of "Huguang filling Sichuan". In addition to the hundreds of thousands of poor people in Huguang, Jiangxi, Guangdong, and Shaanxi ...... As many as more than a dozen provinces, tenant farmers and unemployed vagrants have also joined the ranks of westward migration. This migration, involving millions of people, spanned nearly a hundred years, and in the vast flow of people, including millions of Hakka people, brought sweet potatoes to distant Sichuan.

At this time, sweet potatoes have spread to every corner south of the Yangtze River, and they are beginning to want to advance to the Yellow River Valley.

In the following 100 years, sweet potatoes spread throughout the Qing Dynasty and became the staple food on the table, because of its existence, the scene of starvation all over the wilderness seemed to gradually fade into the vision of the people.

Sweet potatoes fed tens of millions of Chinese people, and the existence of sweet potatoes made the population of the Qing Dynasty skyrocket at a terrifying rate, although there were more people, because of sweet potatoes, the Qing Empire also fed.

Therefore, there are sweet potatoes that create the Qing Dynasty, and some directly turn the Qing Dynasty into a sweet potato empire.

What worries Duhe the most is that sweet potatoes do not exist in China, they only live in the tropical regions of the American continent and are successfully cultivated by the Indians. When Christopher Columbus first met the Queen of Spain, he presented the sweet potatoes he had brought back from the New World to her, and Spanish sailors brought them to the Philippines. During the Wanli period of the Ming Dynasty, China was introduced from the then Spanish colony of Luzon.

This is the introduction of sweet potatoes in Du He's mind, but now it is the Tang Dynasty, and sweet potatoes appeared in the Tang Dynasty, which means nothing else.

Du He felt his heart tremble.
