After going through many difficulties and dangers, bypassing the Nanyang Islands and countless reefs, the Cai family's overseas pioneer group finally found the new continent that Cai Dao said.

In the beginning, the Cai family only found a settlement in the northwest corner of the New World, and the entire northwest part of the New World was all arid and rainless except for the coastal and some river areas. With the current state of science and technology, it is simply not suitable for large-scale immigration to settle here, and there are not many places that are truly suitable for human habitation.

Therefore, in the past few years, the advancement of the Cai family pioneer group's conquest of the New World has not been smooth.

As a result, the Cai family's fleet of seagoing ships had to follow Cai Dao's earlier proposal to follow the coastline from north to south, and then from west to east to find the southeast of this continent, which was the most important place where Cai Dao had established the country.

The Cai family and the Chai family have been secretly competing for overseas immigrants in the Great Song Dynasty, however, Cai Dao's reputation alone is not comparable to the Chai family's ability at all, so it was not until Cai Dao recovered the Sixteen Prefectures of Youyun that the Chai family gathered more than 500,000 Song people on the base of Kyushu Island. However, the Chai family also has the advantage of the Chai family.

There are many children of the Chai family, and now, under the influence of Cai Dao, there is no distinction between descendants and branches, and the whole family works together to create a new country. Moreover, Kyushu Island has a very big advantage over Yizhou Island, which is Cai Dao's base, and that is the Japanese people on Kyushu Island.

Before the failure of the Yuan Dynasty's invasion of the Wa Kingdom, no matter how the Central Plains Dynasty prospered or perished, the Wa people were always afraid of the Chinese people. Even though the Song people were so weak, the Japanese people were still proud to go to the Song State to be vaccinated.

Therefore, as long as the Chai family is attentive, they can sinicize many Japanese people as the subjects of the new country of the Chai family. Moreover, the troops under the command of the Chai family were mixed with a part of the Japanese servant army, which could also reduce the casualties of the Song people during the expedition to the South American continent.

It's a no-brainer.

Cai Dao gave up most of Kyushu Island to the Chai family, and it was for the last reason.

The Southern New World is vast and the aborigines are very scarce, and the Cai family and the Song people who moved there alone are enough to sinicize the aborigines of the world's largest isolated island.

Even now there are hundreds of aborigines in the North American continent, even if the Chai family is full of talents, it is very difficult to completely take over this rich and vast continent, so it is very important to give it an appropriate amount of supplements.

The Song Dynasty finally got its wish and recovered the Sixteen Prefectures of Youyun and the Hetao region.

Although Cai Dao became the middle father, prince and prime minister of the Liao State, he still controlled the situation in the Song Dynasty.

On the surface, under the auspices of Cai You, the construction of the Great Wall of the Song Dynasty, a project jointly supported by the Ministry of Industry and the Ordnance Superintendent, was also fully rolled out in the sixth year of Tianyou.

According to Cai's plan, the people of the Northwest Fifth Road will continue their spring ploughing, but the 800-mile Qinchuan River on the Guanzhong Plain and the fertile Hetao area will not grow cotton or any other grain crops for a long time in the future, and only alfalfa will be planted as a cash crop.

On the one hand, the reason for this is to fallow, and if the grass is lush, it is very beneficial for raising horses and pigs and cattle, and it is forbidden to raise sheep and goats in the Guanzhong area, because, until now, Cai Dao has not found the kind of sheep that are said to not eat grass roots.

On the other hand, it is to conserve water and soil.

Alfalfa is a perennial herb that can be used to raise livestock without continuing to cultivate the land by cutting two or three young grass leaves a year. And, like soybeans, alfalfa naturally replenishes the nitrogen in the land, and its manure can also add phosphorus to the land if there are a lot of chickens and ducks in these areas.

Hedong Road, only the western foot of Luliang Mountain and the southern foot of Zhongtiao Tianshan Mountain. As for the banks of the middle and lower reaches of the Yellow River, they will also be handled in this way, and the scope of influence will be small.

As for the food needed in these areas, Cai Dao made up for the losses caused by fallow in four aspects.

First, with the popularization of agricultural technology, the grain output per unit area in the Great Song Dynasty has been rising, although the annual growth rate is not large, but it is indeed growing.

You must know that Cai Dao did not introduce chemical fertilizers into this era, so it is still difficult to increase the yield per mu on a large scale.

Second, the sixteen states of Youyun, especially the area south of the Yanshan Mountains and Yuguan, and the north of Hejian Fu, the Great Plain of North China was not short of water during the Song Dynasty.

As a result, this area replaced the Gyeonggi region as an important base for grain production in the north from the sixth year of Tianyou.

Third, Cai Dao still did not let go of Da Yueguo.

In the sixth year of Tianyou, the second southern expedition led by Yang's father and son set off from Leizhou again, the same warships and tactics, the same southern soldiers, in the face of the already weakened Yue country, Yang's father and son easily took a large part of the territory of Da Yue.

The southern states of Cham and Chenla did not dare to send troops easily, while the Dali kingdom received Cai Xuan's permission to send troops to recapture the territory seized by the previous dynasties of the Dayue state.

This area is an important grain producing area, and the country of Da Viet is long and narrow, which is very suitable for sea transportation.

Fourth, with Cai Dao's vigorous promotion of pig and chicken farming, as well as the popularization of soybean oil, the soldiers and people in the Great Song Kingdom have begun to use less grain every year.

The more meat and plants you eat, the less food your people need.

Moreover, pigs, chickens and ducks are omnivorous animals, and it is not too expensive to raise them.

On the one hand, Li Qianshun personally wrote to Cai Dao and Xiao Zhaoban, hoping to appoint Cai Dao's younger brother Cai Shan as the prime minister of the Western Xia State.

And his younger brother, who has now been renamed King Gaochang, has married Cai Dao's own sister.

As I said before, Cai Dao's sister and brother, because of Cai Wang's pampering, character and reputation, have already stinked on the streets in Bianliang City.

The boy is okay, the eldest brother Cai Wu married the daughter of a petty official early.

But Cai Dao's second sister has become the first generation of the Great Song Dynasty and the first generation of older leftover women in China.

Unexpectedly, Brother Richard, who had just lost his wife, would be willing to take her.

In this regard, it is naturally Cai Bian and Cai Wang who can make a decision. And they agreed.

As for Cai Shan's visit to the Western Xia Kingdom, Cai Dao's reply was naturally agreed.

After getting Cai's reply, Empress Dowager Meng also agreed.

So far, the three brothers of the Cai family have created a precedent and served as prime ministers of three countries respectively.

Generally speaking, Cai Shan's ability is much stronger than Cai You, but after all, the Great Song Kingdom is the foundation laid by Cai Dao after presiding over the law change. The Western Xia Kingdom lost its fertile Hetao region, and although its subjects were not weakened, their strength was certainly greatly damaged.

In order to divert internal contradictions, three years after the implementation of the reform in the Western Xia Kingdom, Cai Shan suggested that Li Qianshun should lead an army of 50,000 with Li Cha Ge himself, and the leaders of other tribes should lead the troops of each tribe to march to the Western Regions.

The Western Regions is a vast region, and although there are many deserts, there are many places that can be suitable for human habitation.

Once the Uighurs were destroyed, the Western Xia would be able to divide these tribal leaders, who were gradually losing their authority, to the Western Regions.

For example, Brother Richard, who has good military talent, since he is Cai Dao's eldest brother, Li Qianshun does not want to continue to keep him by his side no matter how much he trusts him, even if marrying the eldest lady of the Cai family is still the first idea of the lord of the Western Xia Kingdom.

The monarch of the Han people, and the monarch who was influenced by the culture of the Han people, would have the greatest suspicion of his courtiers rather than trust.

Richard saw this very clearly, so he was very concerned about this expedition to the west.

With sufficient preparation and intelligence, it took only one year for Richard and these Western Xia clan leaders to pacify the entire Western Regions.

And since Cai Dao's sister got married, she has been obedient to Brother Richard as if she was a different person, not only giving birth to many children for her husband, but also becoming her virtuous helper.

In the years that followed, Richard quickly consolidated his rule in Gaochang and, in the ensuing Great War, led his army to defeat the Seljuk coalition, which was ten times his own strength, and dominated all of Central Asia.

Although the common progress of the three countries is not in the short-term interests of the Great Song Dynasty, once the Western Xia State and the Liao State regain their vitality, they can not only block the invasion of the Song State from the nomadic peoples further north, but also stimulate the internal self-innovation of the Great Song State from another aspect.

On the contrary, Yelu Dashi, who was supposed to get this merit, has been leading his troops to encircle and suppress Wanyan and Wanyan Aguda near Huanglong Mansion since the sixth year of the Great Song Tianyou.

The first five years were not so much encirclement and suppression as passive defense. If it weren't for Cai Dao's constant pressure on the opposition of the domestic military in Daliao, Yelu Dashi would have been replaced by someone else.

It's not that Cai Dao is unwilling to change people, or that in the years when he was in charge of the Liao State, he didn't find a single one in the Liao State who surpassed Yelu Dashi in terms of military ability, not to mention, this guy's ability to govern is actually not weak at all.

In such a situation, we can only blame Yelu Hongji and Yelu Yanxi, the two ancestors and grandsons, who are extremely mediocre, and Wanyan Agu fights demons to the extreme.

Yelu Aolugan is not a Ming monarch in essence, and his relatively generous personality is not even a suitable monarch.

A good reputation that does not have any majesty and only relies on benevolence, in the Great Song Dynasty, that is Renzong, but who let him grow up in Liao?

Fortunately, Cai Dao became his middle father, and the new law implemented also put an end to the previous practice of the nobles surnamed Yelu and Xiao of the Liao State controlling the government. The new forbidden army of the Liao State is naturally not comparable to the strength of the Liao State in the early years of the founding of the country. Cai Dao also confessed to him.
