The Andong area is a part of the mountainous hills of Liaodong, which is a branch or residual vein extending from the Changbai Mountains to the southwest, and the terrain gradually decreases from northeast to southwest.

According to the height and topographic characteristics, it can be divided into three large-scale landforms: the middle and low mountainous areas in the north, the hilly areas in the south, and the coastal plains in the south.

Among them, mountains and hills are the mainstay, and there are small landforms such as terraces, basins, and terraces. In addition, because of the abandonment of the land for many years, the mountains and forests here are extremely lush.

In the Andong area, the northern part of Kuandian and Fengcheng has the highest terrain, with an average altitude of about 500 meters, 14 peaks of more than 1,000 meters, and the highest peak, Huaneck Mountain, is 1336.1 meters above sea level.

These high mountains can be used as an important node for our army to defend against the Houjin attack, and firmly intercept the iron hooves of the Houjin army moving south.

Moreover, because it is close to the Yalu River, it is extremely convenient whether you want to support or retreat.

The central and southern parts of Fengcheng and the north of the eastern port, with an average altitude of 300 meters to 500 meters, the central and southern parts of Andong Port have the lowest terrain, the altitude is more than 20 meters, and the lowest altitude is below 2 meters, which is very suitable for the construction of the port.

The Andong region has four distinct seasons, is the warmest and wettest place in the eastern Liaodong region, in the minds of the older generation of Liaodong people, known as the "north of the Jiangnan", "the northeast of Suzhou and Hangzhou".

Andong has the longest winter time, followed by summer, and the shortest spring and autumn transition season. It has a lot of precipitation, and it is the area with the most precipitation in eastern Liaoning, accounting for about seventy percent of the precipitation in Liaoning Province, and the water source is sufficient.

Most of the annual precipitation is concentrated in summer, and the heavy rainfall in the region is concentrated from mid-July to mid-August.

Moreover, there are 944 large and small rivers of more than 2 kilometers in the whole region, including 4 large rivers and large rivers with a basin area of more than 4,983 square kilometers, namely the Yalu River, the Hunjiang River, the Danghe River and the Dayang River. ”

Chen Xin nodded, and was very satisfied with this area in his heart, but this place had the same significant shortcomings as Vladivostok just now.

On the Vladivostok side, the weather is too cold, the winter break is too long, the construction is not easy, and it is a waste to have to rest for hundreds of days every year.

Dandong, on the other hand, has a vast territory, and although there are high mountains that can be used as barriers, it is unknown whether these so-called barriers can play a role in the face of those highly mobile Houjin cavalry. Once the Houjin army has the ability to cross those high mountains, on the plains, as long as the enemy invests far more troops than its own, then it will definitely be able to inflict great damage on its own side.

But at the same time, the advantages of these two places are also very obvious, which makes Chen Xin a little undecided.

This is related to the overall strategic direction of the kingdom in the next step, and there is no room for sloppiness.

Therefore, he is not in a hurry, after all, there is an address, which has not yet been explained, and he still doesn't know what the conditions are there.

Thinking of this, Chen Xin took a sip of tea and said, "Let's talk about the third location you chose." ”

"Yes." Bowing again, Lao Chen turned around again, pointed to the important place on the opposite side of the Shandong Peninsula on the map, not far from the Daming Jingshi, and said, "The third venue we chose is the peninsula area of Jinzhou, Fuzhou, and Lushun.

In this area, since the Yan State set up the "Liaodong County" in Liaodong during the Warring States Period, until the Qin and Han dynasties, the entire peninsula area belongs to the jurisdiction of Liaodong County.

During the Western Han Dynasty, the Dalian area was set up as "Yushi County", and during the Three Kingdoms period, it was renamed "Dongyu County".

At the beginning of the Tang Dynasty, it was under the jurisdiction of Jili Prefecture, the capital of Andong.

During the Liao Dynasty, the Dalian area belonged to the jurisdiction of Liaoyang Prefecture in Tokyo, and the Han law was implemented for the Han District.

After the Wei and Jin dynasties, it was also called Sanshanpu, and in the Tang Dynasty, it was called Sanshanpu, and when it came to the Ming Dynasty, it was called Sanshan Haikou.

Sanshan Haikou is the gateway of Beijing and Tianjin, north of Yingkou, south and Shandong Peninsula across the sea, and Daming Shandong, Beijing-Tianjin, Guanning Army, Wa Kingdom, Korean Kingdom, Houjin and East China Sea regions and forces are adjacent, can radiate most of the surrounding sea areas.

There are many mountains and hills in this area of Sanshan Haikou, and there are few plains and lowlands, and the whole terrain is high in the north and low in the south, wide in the north and narrow in the south.

The topography of Sanshankou is inclined from the central axis to the Yellow Sea and the Bohai Sea on the southeast and northwest sides, and is long and gentle on the side facing the Yellow Sea.

The remnants of the Qianshan Mountains of the Changbai Mountains run through this area, most of which are mountains and low hills formed by erosion for a long time, and the plains and lowlands are only scattered in the places where rivers flow into the sea and some mountain valleys, and karst terrain can be seen everywhere.

Sanshanhaikou is the warmest place in Northeast China, with no severe cold in winter and no scorching heat in summer, and the four seasons are distinct. Precipitation is abundant.

Sanshanhaikou and the entire peninsula region are the hottest in August of the year. January is the coldest month.

About 60 to 70 percent of the precipitation is concentrated in summer, with more rain and more rain at night than during the day.

There are two major water systems in the Sanshan Haikou area: the Yellow Sea Basin and the Bohai Sea Basin.

First, the larger rivers that flow into the Yellow Sea include the Biliu River, the Yingna River, the Zhuang River, the Zanzi River, the Dasha River, the Dengsha River, the Qingshui River, the Malan River, etc.

Second, the main rivers that flow into the Bohai Sea are the Fuzhou River, the Liguancun River, and the Sanshilipu River.

Among them, the largest river is the Biliu River, which is the source river for inter-basin water diversion in the urban area. In addition, there are more than 200 small rivers, and there are many ore veins found.

In general, Sanshan Haikou is very rich in natural resources. ”

Chen Xin looked at that area and immediately reacted, isn't that the Dalian City of the later generations, a famous tourist city in the country.

However, Chen Xin thought for a while and asked, "Old Chen, how can I remember that this region, until now, is still the territory of the Ming Dynasty?"

At the beginning, this place was broken by the Later Jin army, and then, Mao Wenlong, who was killed by Yuan Chonghuan's false will, led his troops to recapture Jinzhou and Fuzhou.

And I forgot that this year or last year, when we collected the victims of the disaster in Dongjiang Town, we also secretly cleaned up a group of traitors in Dongjiang Town who were ready to take refuge in Houjin.

At that time, didn't a part of the Ming army go ashore and strengthen the defense force of the Ming official army in Jinzhou and Fuzhou? ”

"Your Excellency's memory is so good, it's not wrong at all. It really belongs to the Ming Dynasty now. The butler smiled and flattered.

Chen Xin frowned slightly, and after a period of self-cultivation, he came out again, his fingers kept tapping on the armrests of the chair, and then slowly spoke.

"Lao Chen, you should know that having a good relationship with Daming, at least, not causing conflicts on the surface, is the guidelines and policies I set in advance for an important event that is likely to occur in the future.

You don't want the kingdom to lose a great opportunity to dominate the Central Plains for the sake of a mere Liaodong, right? ”

The housekeeper hurriedly shook his head, "Your Majesty, of course the minister can't mean this, please listen to the minister's explanation." ”

Chen Xin nodded, "You say." ”

Lao Chen then explained, "Although it is under the banner of the Ming Dynasty, since Mao Wenlong's death, it has almost been abandoned.

Huang Long, the newly appointed commander-in-chief of Dongjiang Town in the Ming Court, was weak, incompetent, and greedy, and did not dare to attack Houjin externally, and internally, he constantly squeezed the salaries and rations of his officers and soldiers, and was completely unpopular with the officers and soldiers of Dongjiang Town.

Moreover, when the soldiers and horses of Dongjiang Town on each island went to the east and west, some of them did go to take refuge.

Huang Long also did a very inauthentic job with these colleagues who went to take refuge in him, and the oppression was too much, which had caused several mutinies, and his own nose was cut off.

Now that Huang Long, who has lost face, he can't suppress his subordinates.

On the side of the Ming Court, at this time, the war in the Dalinghe region was still entangled, and it was beyond the reach of the Jinzhou region at all.

According to the speculation of the intelligence department, as long as the Houjin army arrives, the cities of Jinzhou and Fuzhou will definitely not be guaranteed.

Looking at it, the geographical location of this place is really excellent, and it basically meets the needs of our army for a long time in the future.

Therefore, the minister had the courage to add this place to the shortlist.

If the king can be sure that this place is needed, the minister has a way to make the kingdom and the Ming Dynasty not fight each other because of this place. ”

Looking at the sworn old Chen, Chen Xin's eyes narrowed slightly.

This housekeeper is not simple.
