In the following days, the advance of the people of the Great Song Dynasty was quite smooth, although they occasionally encountered sporadic resistance from the aborigines, but on the whole, in the face of the powerful Song army armed group, the aborigines also reflected the wisdom of higher animals, that is, they knew the current affairs, and the situation soon turned into confrontation and cooperation, and the aborigines accepted compensation and were happy to barter with the Song people.

The people who marched to the northern tip of Taiwan went up the source along the river that they could find according to the plan in advance, and made a lot of money in the trade with the aborigines, because many aborigines could not only take out fur exchanges, but also take out gold to exchange for the goods of the Song army, fortunately, the Song army was well prepared, and the accompanying boats were equipped with various items that the aborigines loved, such as clothing, food, etc., and the aborigines did not understand the real market of gold, so the Song army took advantage of the exchange.

Since the aborigines possessed gold, it proved that gold was produced nearby, so the Song army began to pay attention to the search for gold veins, and the efforts paid off, and a team of Song troops found sand gold in the river. It seems that Shangguan's explanation is good, and this place may really be rich in gold. However, it is not a day's work to find the main gold vein after all, but this news is already very encouraging, and then the news was reported layer by layer and reported to the Chinese military account of Penghu Zhao Luan.

Zhao Lian has also been very pleased with the progress of people from all walks of life these days, and swept away the previous bad luck. There is sand gold at the northern tip of Taiwan, which proves that Mao Geng's statement that there are gold and silver mines there is ninety percent true, and in addition, he also found a basin there, the basin is fertile, and the rain is abundant, which can be cultivated and planted with rice. And to the south, the water 6 two roads advanced, into a huge plain, the climate is warm, the water flow is vertical and horizontal, as Mao Geng said, this is a fertile field, over time, it can become ten thousand hectares of fertile land.

But what makes people scratch their heads is that all the way forward, there are already seven or eight ethnic groups of aborigines encountered, all the aborigines speak in a hurry, no one can understand their language, and they have no words without exception, so gestures are popular in the Great Song Army, and many guys who are not effective in combat in peacetime are just because they can happen to understand the gestures of the aborigines, and they have become a celebrity in the Song Army for a while, which can only make people sigh that feng shui is really turning.

Mao Geng has not been idle these days, and the Song army to the south has encountered a miasma, so although the south is a fertile field, how to prevent miasma has become a top priority. Because of the prior training, Song Jun already had an understanding of miasma, and understood that the so-called miasma is the gathering of flying insects that are difficult to distinguish with the naked eye due to the untreated animal carcasses, to be precise, it is a group of poisons flying in the air, so on the one hand, smoke is used to drive away miasma, and on the other hand, some food and herbs are specially used to prevent miasma, including betel nut.

Another focus of Mao Geng's attention is the food eaten by the aborigines, which is related to whether new crop species can be found in Taiwan, so all walks of life have the responsibility of collecting various foods from the aborigines.

The food collected by the aborigines was nothing more than meat, millet, taro, and no other unique species, and so far, no aboriginal people have cultivated rice. But on this day, a team of centaurs exchanged a bunch of fruit-like things with fibrous roots from the aborigines, which can be eaten raw, and the mouth is sweet and crisp, obviously not taro. This pile of strange things was sent to Penghu, and Mao Geng saw it at a glance and immediately recognized it as a sweet potato. Mao Geng was overjoyed, and said in his heart that this was originally a South American species, and I don't know when it came to Taiwan from South America, or the sweet potato was originally born and raised in Taiwan.

In Mao Geng's original history, sweet potatoes were not introduced to China from the Philippines until the 16th century, but I didn't expect sweet potatoes to appear in Taiwan at the end of the 12th century.

Sweet potato can be called the highest yield of food crops, although it is a coarse grain, but the introduction of the big 6 a day earlier, can save thousands of people from starvation, for this, Mao Geng even feels more meaningful than gold.

Zhao Lian asked people to cut a piece and tasted the novel food that Mao Geng called sweet potatoes, and felt that the taste was still good, but Zhao Lian had tasted a lot of melons and fruits in his life, and his mouth was more tricky, so he just praised it casually and didn't take it seriously.

In this regard, Mao Geng had no choice but to introduce the benefits of sweet potatoes:

"Guogong, this sweet potato is a good thing, with this sweet potato, you can ensure that there is no hunger in the Great Song Dynasty, which is really a blessing for the people of the Great Song Dynasty."

Of course, Han Yanxuan didn't believe Mao Geng's words, there was a famine in the Great Song Dynasty, just because of frequent natural disasters, Mao Geng's words were obviously exaggerated. However, Han Yanxuan didn't want to hit Mao Geng too much, so he said:

"Mao Geng, the world is easy to say, but in fact, it is not easy to get a wheat, the poem says that the grains are hard, you and I are not farming people, I don't know that farming is difficult, since ancient times natural disasters locusts, can not be prevented, the same crop is magical, helpless when the disaster comes, unstoppable, just rely on this thing, can ensure that there is no hunger in the world? It's okay to talk about it here, if you boast about it in the court, you will be made fun of. In order to relieve the famine, the Great Song Dynasty set up Changping Warehouse, Shecang, Yicang, Huimin Cang, Guangfeng Storage Warehouse and Pingping Cang, even so, it was not enough to cope with the disaster. Mao Geng, don't talk nonsense if there is no hunger. However, since you are so boasting, there must be some benefits to this thing, so it is better to tell the prince about it. ”

Mao Geng said in his heart, you don't know that this thing is magical, and after you know it in the future, you may not say so.

Zheng Zhi also tasted a piece of sweet potato, and was very curious about such a thing, so he said:

"Mr. Mao seems to be familiar with this thing, so let's talk about its benefits, and let me have a little more knowledge!"

Mao Geng is of course very familiar with sweet potatoes, in the early sixties of the later generations relied on sweet potatoes to survive a food crisis, he has done a lot of sweet potato seedlings, harvesting sweet potatoes farm work, and has eaten more sweet potato products, of course, a qiē has to be pushed to the head of the master, so he introduced like a few treasures:

"Shizun once said that the yield of sweet potatoes is extremely high, one or two thousand catties of sweet potatoes can be harvested in one acre of land in one season, and the current territory of the Great Song Dynasty can grow two seasons of sweet potatoes a year, and it is not difficult to produce three or four thousand catties per mu. As for Fujian, Guangdong, and Taiwan, which have a hot climate, sweet potatoes can be planted all year round, like here in Taiwan, it is not difficult to produce seven or eight thousand catties of sweet potatoes per mu all year round. There is also an advantage, sweet potatoes do not choose the land, barren, drought resistance, it can be said that they can be planted anywhere, such a good food crop, today, it is really the luck of the Great Song Dynasty. ”

When Zheng Shi heard this, he couldn't believe it for a while, so he asked:

"It's so amazing! At the end of the day, I heard that one mu of rice can only harvest two or three hundred catties of rice at most, and the rice in Fujian and Guangdong can be harvested twice a year, and at most 500 catties of rice. If this sweet potato can be used as food, it will definitely be a great achievement, and it is a miracle for the benefit of the Great Song Dynasty. ”

Zheng Zhi said this, and attributed all the credit to Zhao Luan, and Zhao Luan's heart also began to be eager, and he suddenly changed his previous carelessness, and asked solemnly:

"Mr. Mao, is this serious?"

Then he said:

"Even if you get some discounts, you can harvest more than 1,000 catties of sweet potatoes per mu, which can fill the food of famine, which is also very good."

Zhao Lian knew that the emperor's grandfather loved the people and attached great importance to farming, and if he could offer a high-yield grain crop this time, the emperor's grandfather would naturally be happy. The emperor's grandfather Longyan Dayue is still a trivial matter, if it can be like Mao Geng said, the Great Song Dynasty may really have less hunger from now on, and the people will not starve to death from now on, in any case, this is a good thing for the country and the people. Zhao Lian thinks that if this is the case, this time to take Taiwan, not only is it quite affordable, but also the added value is unexpectedly high.

Mao Gengxin said that the yield per mu of the excellent varieties of later generations will be more than 10,000 catties, and I don't know how high the yield of this sweet potato variety is now.

"Guogong, it's useless to talk about this matter, it's better to find a place in Penghu to try planting, and you will know the truth or falsehood."

Han Yanxuan looked at Mao Geng curiously and said with a smile:

"But none of us can grow sweet potatoes, do we have to ask those barbarians to teach us?"

Mao Geng smiled and said:

"Master Han, don't worry, Master once said how to grow sweet potatoes, you can try it, maybe it won't be bad."

Of course, it won't be bad. Who wouldn't plug sweet potatoes! Doing other farm work may be almost, but plugging sweet potatoes, the students of the seventies in the later generations have done the work of inserting sweet potatoes when they were working and studying, and they came to the Great Song Dynasty to plant sweet potatoes, not to mention, to achieve a yield of 1,000 catties per mu, it is still quite sure.

(How sweet potatoes from the Americas came to Taiwan are divided into two schools of thought.) One faction was brought to the Philippines by Europeans during the Age of Discovery, and then introduced to the Ming Dynasty from the Philippines, and the Han people of the Ming Dynasty introduced sweet potatoes to Taiwan. The other group advocates the introduction of Taiwan by the aborigines. Most of the traditional foods of Taiwan's 14 aboriginal ethnic groups are millet, sweet potatoes and taro, and the aborigines should have a certain credibility in introducing sweet potatoes to Taiwan by their own efforts. ）
