Starting to divide the Jurchen tribe from the beginning would greatly reduce their threat to the Great Song Kingdom in the future.

And taking the initiative to occupy a small part of Sakhalin and establish a permanent supply and defense base there can also attack the Jurchen possessions from behind in the future against the Jurchen regime. Although Ezo Island is also capable of undertaking this task, Sakhalin Island is very close to the hinterland of Liaodong after all. It is also the mouth of the Heilongjiang River, and even if there is only a few months of thaw in a year, the Cai family's fleet can still take advantage of this period to interfere with its hinterland.

Turning around, let's talk about the Cai family's top priority overseas - Yizhou Island.

There are not many aborigines in primitive costumes on the island today.

Those tribes that had been hostile to the Song people who had moved to the island had long been completely wiped out by the soldiers sent by the Cai family, and the person in charge of this task was Du Menghu, the former third master of Taihang Village.

This was the task assigned to him by Cai Dao, and once this task was completed, Cai Dao allowed Du Menghu to lead his troops to occupy Shikoku Island, another island of the Wa Kingdom. It will be attacked and occupied by him and You Feixiong.

Now, Cai Dao's troops want to attack the Honshu Island of the Japanese Kingdom, but they still have no strength, after all, if they are defeated, they have to be occupied and managed. Cai Dao's subordinates today are very lacking in such talents. On the contrary, as long as the warship is in hand, as long as the lord of the Wakoku Kingdom on the island of Shikoku is taken, the emperor of the Wakuni Kingdom and the Fujiwara clan in power are completely unable to take Du Menghu and You Feixiong.

As for Kyushu Island, where there is still more than half left, it is the territory that Cai Dao himself has already booked, and naturally outsiders will not be allowed to occupy it. This is also an important reason why these two village owners were willing to be driven by Cai Dao before.

Because, Cai Dao and the two of them had already agreed when they met for the first time. Cai Dao was responsible for providing warships, weapons, and other necessary military supplies, and transporting the two village owners and their men to Shikoku Island, and Cai Dao was not at all involved in recruiting men and attacking and occupying the entire island.

After You Feixiong and Du Menghu occupied Shiguo Island, Cai Dao would not drive these two village owners to do anything. After that, the relationship between the two sides is no longer subordinate.

For such conditions, these two ambitious heroes were naturally happy to agree. Although, during this period, Cai Dao also assigned some things to the two of them. However, the two village owners still completed the task assigned to them by Cai Dao very well.

Three years later, in the summer of the third year of Yuanyou, the Cai family's fleet transported the two village owners and their men to Shikoku Island at one time.

At this time, Shikoku Island did not have the very bullish Changzong My family, and under the leadership of the two fierce generals, You Feixiong and Du Menghu, the resistance forces on Shikoku Island quickly collapsed. On the island of Honshu, after receiving the news, the Japanese mainland sent a large army to help, most of which led the samurai and soldiers to surrender, and a few recalcitrant rebels went to the sea to become kings.

On Yizhou Island, those hostile tribes were wiped out by Du Menghu, and after the Cai family showed strong force, the remaining tribes were relatively mild, and the tribes that did not participate in the last massacre had to choose to submit. Cai Sansi ordered the people of these tribes to change their customs and mix these people with the Song people who migrated over.

It was mandatory for these people to actively integrate into the Song people.

As for the leaders of those tribes, those who are willing to join the army can enter the naval academy opened by the Cai family, and they will have the opportunity to become the lord of an island in the future.

After all, there are as many islands in the South Seas as as many as stars, and those five or six main ones, Cai Dao is ready to give to his subordinates with the most merits, and the rest of the islands are up to their own abilities.

As for those who are unwilling to serve Cai Dao, Cai Dao will not force them, and gives ten acres of land to their clansmen, these people can do business, and the Cai family can provide them with sea ships to use for business.

However, there is one thing, these leaders, their families, and their people have all been relocated to the later Taizhong region. The Cai family built a large city there, and built a super-large shipyard and dock in Haiben.

Among those leaders, the older ones are not very willing to work for the Cai family, and there are not even many leaders who are willing to do business at sea. However, their families, especially some young people, are willing to enter the Naval Academy, and Cai Dao even allows girls to join the academy. Therefore, in the naval academy in Taiwan, young people still account for the vast majority.

These people are naturally unwilling to abandon their homeland for I don't know how many years they have lived in vain, but in the face of powerful force, they can only choose to surrender. In the beautiful blueprint that Cai Dao portrayed to them, these young people are also ambitious. The broadening of their horizons also allowed them to open their minds and take the initiative to absorb the knowledge taught in the school.

Of course, the desire of these young men to join the navy quickly and to cross the sea with their clansmen will be put on hold for a long time.

Today, Cai Dao's migration from the north of the Great Song Dynasty is still too small. In Cai Dao's planning, when more than 500,000 people lived on Yizhou Island, it was the time when the Cai family's fleet attacked the entire Nanyang Islands.

Before that, Cai Dao wanted to capture enough slaves for the Great Song Dynasty and replace the Song Dynasty people he secretly transferred. And Da Yue is undoubtedly such a good target.

There is a deep hatred, but there is enough food and population.

The seaport in Taichung was named Xingang by Cai Dao.

Now the shipyard in Xingang is completely making large warships for the Cai family. The warships made by the Cai family today are naturally not as good as the warships of Western countries in later generations, and even the biggest lucky ships when Zheng He went to the West. However, in this era, the warships built by the Cai family are undoubtedly huge sea monsters when driven by outsiders.

On Yizhou Island, there are many tribes that immediately take the initiative to surrender when they see these warships.

However, with the continuous improvement of the shipbuilding technology of the Cai family shipyard and the development of the northeast part of the mainland, the Cai family was able to obtain more and better shipbuilding timber. As time passed, the warships built by the Cai family have become larger and larger.

Today, there are large warships of more than 3,000 tons with a layer of steel plates at the bow and stern.

In the East China Sea, there are many extremely small islands and extremely small countries, and the Cai family naturally will not and there is no need to occupy them one by one. However, in the Xiaoliuqiu Islands, Cai Dao will not let those above establish a country. Although these islands are small, they are also rich in rice, and these islands are closely linked to the connection between Yizhou Island and Kyushu Island, so the Cai family naturally will not let these islands be controlled by others.

Therefore, in the third year of Yuanyou, after repelling the reinforcements of the Japanese navy, the Cai family fleet captured the Xiaoliuqiu Islands on the return trip.

At this point, under Cai Dao, the Cai family's fleet has completely dominated the entire East China Sea.

At this time, after repeatedly hitting a wall, Yang Wei, the Qincha, ushered in two guests in the line of the Qincha in Taiyuan Mansion. Looking for Cai Dao's matter, I finally have an eyebrow.
