In the early morning, the East China Sea Navy fleet sailed along the sea near the Hokkien landed at the north of the Whale Sea, which was the Tatar Strait in later generations.

Later Japan called it the Miyagi Strait, and polar bears called it the Neverskoy Strait.

It is a water area between Sakhalin Island and the mainland. After passing this strait that runs through the north and south, it is the Sakhalin Bay in later generations, and then the Sea of ​​Okhotsk. But now these places have been named "North Sea" by Zhao Gou!

The wind on the sea is very cold and the temperature of the sea water is very low. It is the end of March, and the Central Plains is already in spring, but it is still as chilly as early spring. However, the ice layer on the sea is dissolved thoroughly.

Liu Ziyu stood at the bow of the boat, looking at the coastline map drawn by the staff members, while looking at the surrounding sea surface.

From entering the Tatar Strait to the entrance of the destination of the Qiantong River, there are more than a thousand miles of sea routes.

"Nuergancheng!"

This is a city at the northernmost end of the Huntong River. It was built in the hands of the Liao people and now belongs to the Jin people. It is a stronghold of the tribes around the entrance of the Huntong River. The surrounding small tribes pay tribute to the Wanyan Jurchen every year. It is also a frontier base for the Wanyan family to capture the Huli Gai people.

Because the area north of the Huntong River is too vast and the environment is too harsh, the tribes here are also restless, just like the Liao people have to bear the backlash from the grassland tribes, the Jin people, even though they see that they are from the White Mountains and Black Waters, are also going to be rioted by tribes that are further north than them.

Before Aguda had even raised an army to rebel the Khitans, Wanyan Jurchen had to send troops from time to time to pacify the tribes that were not convinced by the Huntongjiang River Basin. At the same time, this was also a way for Wanyan Jurchen to expand his strength.

These captured wild Jurchens are wilder than Wanyan Jurchens.

Life and death are indifferent and move forward. For those savages, the "comfortable" days of the Jurchens are profitable if they can live a day. After they die, their families and even tribes have many benefits, which makes them even more fierce and fearless.

The Huliga people, located in the estuary of the Huntong River, are tribes that are further north than the Ye Jurchens. Moreover, in the Jurchens' "national concept", they are not the same ethnic group as the Huliga people at all.

During the period of Wanyan's siege (Aguda's father), in order to eliminate the threats behind Huligai people, he wanted to use the strategy of in-laws to win the favor of the Wuchun tribe among Huligai people, but was scolded by Wuchun as a pig and dog: "How can the son of the dog be with you? How can Huligai and his daughter be close?"

Then Huli Gairen was exhausted by Wanyan's impeachment, causing him to fall apart and cannot reunite, and he could no longer become a threat to Wanyan's Juzhen.

What about Wanyan's siege Libo? Since he succeeded to the throne and became the governor of the Jurchens, the Huli Gai people took advantage of the siege to attack, rebelled inside and outside, and formed enemies. Huan Nan, Sanda, Wuchun, Wumouhan and other Huli Gai tribes, each of which was a powerful enemy that the Jurchen tribes had to face seriously at that time. However, during the confrontations year after year, Huan Nan, Sanda, Wuchun, Wumouhan and other Huli Gai tribes disappeared one by one along the Huntong River.

In the seventh year of Da'an in Liao, Huligai people completely surrendered to Wanyan Juzhen. In the eighth year of Da'an, Wanyan's terror was killed. The one on the other can be said to be a lifelong enemy.

But once and forth, even Aguda has been dead for six or seven years. Thirty or forty years have passed. In such a bitter and cold place, thirty or forty years is the scene of a whole generation. Liu Ziyu kept muttering some tribal names in his mouth. This was a little bit of information that the Jinyiwei finally found, but no one can tell whether it was accurate or not.

He really couldn't predict whether he could take some of Huli Bing for himself in the next time? Perhaps Huli Bing had long forgotten his grudges with the Jurchens.

In this way, time passed by day in Liu Ziyu's guess until he saw the mouth of the Huntong River.

In the afternoon of the next day, two small sea boats lowered most of the sails one after another, and put down several small boats to measure the depth of the river channel. Although this Huantong River is a well-known river, the area at the mouth of the sea was too unfamiliar with Song Junyan. It would be better to be cautious.

Liu Ziyu held the Qianli Miles and looked at the two sides, but there were no traces of indigenous people appearing. On the contrary, the shore was full of dense green pine and birch forests. His tall and straight figure made people shocked. At the same time, he could also see large swamp areas, where green grass just now seemed to grow directly in the water, with green patches of water and light mixed together, extending far to the shore, so that the Qianli Miles and mirror could not see the reflection of the water.

It is said that the flow and depth of the Huntong River are by no means that the ships of this era can only surpass.

"The first thing I do when I get ashore is to set up tents, log wood, build houses, and build camps, right?" Liu Ziyu wrapped in a fur coat, wearing black leather shoes, and walked on the soft grass in Jiangnan.

This land does not have much strategic significance, at most it is just a stop. Because it is the outermost edge of the estuary of the Qiantong River, and the terrain is low, just like Pudong in the Magic City. Whether it is erosion of tides, sea water backflow, or the arrival of a flood season, the safety hazards of the lower altitude ground can prove that this place is not suitable for large-scale ground construction.

Huntongjiang also has a flood season. Whether it is heavy rain in summer (rainfall), melting ice and snow after spring, or even ice and ice after the temperature drops sharply, it can also cause heavy floods.

What's more, the entrance to the Huntong River is a big trumpet. What is really strategically valuable is not such a trumpet, but the trumpet inside. It is also the location of the temple streets in later generations.

There can be crushed the current land of land, whether in terms of geographical environment or geographical advantages. As for the strategic elements, it can crush it and then crush it.

When Liu Ziyu took a boat to the trumpet, he took a look at the area on the north shore at first sight. The large plains were beyond the limit. And it was stuck in the Huntong River Estuary, which was definitely an excellent place to control the Huntong River Estuary.

As for Nuergan City, it is of course a good place, but Zhao Song had to maintain control over the lower reaches of the Huntong River. Its strategic direction was different from the land conquest routes taken by the Khitans and Jurchens. The most cost-effective way was to go through water and sea routes.

Although this place is in a state of inaccessible for half a year, the only half a year of navigation is enough for Zhao Song to turn around and operate.

Because of today's technology, the only thing that can be coveted by the people of the Central Plains in the outside world is the fur here.

The so-called rule and the so-called management are, in the end, simple material exchanges based on high profits, and perhaps employment for the young and strong population here. Just like Zhao Song did to the Hengshan Zhufans.

The former contains huge economic interests, while the latter has certain strategic and political significance.

"But these are all long-term considerations..." Liu Ziyu took a sip of strong wine and his whole body immediately became hot.
Chapter completed!
