The World of Yellow Sky

In ancient China, there were only a handful of countries that could rule the world.

The reason for this is that the geographical advantage in the south occupies a great advantage.

The Eastern Jin Dynasty, Southern Song Dynasty, and a number of Southern Dynasties relied on the Jianghuai region, and were able to settle down in a corner.

The Huaihe River and the Yangtze River are natural dangers in the true sense.

In the middle reaches of the Yangtze River, there are staggered hills and dense vegetation, stretching for thousands of kilometers, making it impossible to carry out comprehensive defense.

However, it can rely on Xiangyang, Yichang and other important towns along the river to guard, and it only needs to set up heavy troops in the key points of the tributaries, and it can effectively imitate the northern troops going south.

Historically, the combat power of the Southern Song Dynasty was weak, while the Mongolian cavalry had already dominated the world at that time, and it was at its peak, sweeping almost the entire Eurasian continent.

At that time, the Mongols who invaded the south not only had powerful cavalry, but also a large number of elite infantry, and a siege weapon such as counterweight trebuchets, but they were still blocked in Xiangyang City.

Song Meng fought fiercely in Xiangyang, both sides tried their best, but in the end because of the isolation of the city and no support, the defender Lu Wenhuan chose to surrender.

The Battle of Xiangyang lasted nearly six years and ended with the fall of Xiangyang in the Southern Song Dynasty.

The fall of Xiangyang also marked the end of the Southern Song Dynasty. Since then, the Southern Song Dynasty has been in a slump, and the Mongolian army has driven straight in.

Six years later, in the battle of Yashan, the Song army was defeated.

Lu Xiufu was completely desperate. After appeasing the young master, he tied Guoxi to the young master, carried the young master on his back and jumped into the sea to commit suicide. The Southern Song Dynasty perished.

The lower reaches of the Yangtze River have a humid climate, flat terrain and fertile land.

The Yangtze River is indeed a natural moat, but the water flow in the downstream area is slowed down, and the shoals are everywhere, making it easy to cross the river, and there is no danger at all.

Therefore, since ancient times, there has been a saying that if you guard the river, you must guard the Huai River.

Because if you only guard the Yangtze River, you will not have any strategic depth. Once the northern army crosses the river, it will be impossible to organize effective resistance and counterattack.

Nanming and Nantang are the best examples. They did not occupy the Huaihe River area, but only relied on the Yangtze River, and they were easily wiped out.

To guard the river, we must guard the Huai River, and the Huai River can also be connected with the Qinling Mountains to prevent the northern army from going south.

It is precisely because of this favorable location that there was a long period of confrontation between the North and the South in ancient times.

Xu You stepped forward and pointed to the locations of Yutuyang and Jingzhou, and continued to talk.

Although he is not as good as Jia Xu in terms of strategy, he also has his own unique insights in analyzing problems.

"Our infantry is tough and has the advantage of heavy armor training. They are used to fighting in the field, but they mostly fight on the plains."

"Our army has a large number of cavalry and is good at fighting on the plains, but the south has many hills and less flat land, and the river network is densely covered, making it difficult to gallop."

"Even if our army captures Yanzhou, it will gain very little. From Yanzhou to attack Qingzhou, there are only two main routes to attack. The Qingzhou army only needs to set up defenses in two places to stop our army from advancing."

Jia Xu's eyes were bright, and her voice was involuntarily high.

"Occupying the two prefectures of Yan and Henan and forcing the Han court to move south will only damage the prestige of the Han court, and it is difficult to accomplish all of its achievements in one battle."

"The Yanzhou Han army has [-] troops, many of which are reinforcements from Xu, Yang, and Henan. Part of the Xuzhou army went north to help Qingzhou, and a part went west to help Yanzhou. The defense must be empty."

"Yangzhou's defense at the rear is naturally not given priority by the Han court. Even if it is prepared, it is definitely much weaker than the defenses of Yanzhou and Jingzhou."

"Our army took advantage of the situation and went south to Yangzhou. As long as we occupy the river bank, we can cut off the way for the Han court to retreat to the south."

"At that time, the back of the Han court will be cut off. Our army only needs to cross the Yellow River and defeat Yanzhou to rule the world!"

Xu An looked at the map in front of him with his hands behind his back.

He originally planned to use the navy to attack Qingzhou.

It's just that his idea at the time was to attack at the same time from Yanzhou and Qingzhou and advance side by side.

But Jia Xu's arrival this time made him discover the problem.

Attacking Yanzhou first will only make the Han court move south immediately, abandon Yanzhou and the northern part of Yuzhou, and directly retreat to the Huaihe River and the Yangtze River.

The Han court retreated to the Jianghuai River, at the cost of losing the entire territory of Yanzhou and the northern part of Yuzhou, but it was able to regain the strategic initiative

The lower reaches of the Yangtze River and the Huai River are connected by two waterways.

They are Zhongdu Waterway and Hefei Waterway respectively.

As long as these two waterways are occupied, the Yangtze River Navy can directly enter the Huaihe River through the two waterways.

The Huaihe River Basin is extremely vast, with its tributaries spread all over, and the water is abundant, and many warships can also sail on it.

With the advantage of the navy, the logistical supply pressure of the Han army is almost negligible.

Most of Yuzhou will be under the vanguard of the Han army, so even if the Ming army occupies Yuzhou, there is no way to develop well.

And the most important thing is that the south at this time is not the southern region that has been developed in later generations.

During the Han Dynasty, the south was only initially developed, and it had not yet become a land of fish and rice for later generations.

At this time, the southern region has just begun to be developed, and many places are still virgin forests, densely covered with rivers and swamps, full of miasma, dangerous roads, and difficult transportation.

The development of Jiangnan is mainly still along the Yangtze River and the lower reaches of the Yangtze River Delta, as well as Lingnan and the Pearl River Basin.

However, the inland areas are still not developed and sparsely populated.

During the Eastern Han Dynasty, there were still many Shanyue people in the interior of the southeastern region.

Jia Xu and Xu You are constantly perfecting the plan.

Soon, the prototype of a new southern expedition plan was drawn up.

It's 62 characters short...shouldn't be scolded.

8 Chapter Thirty

The first ten days of April in the fourth year of the Ming Dynasty (197).

The land of the Central Plains is already in the season of warm spring and flowers blooming, but today's Liaodong is still in the midst of cold weather.

The north is cold, but the human blood is extremely hot.

Among the mountains and mountains, there was endless shouting and killing.

The flock of birds wandered back, and the beasts ran in all directions.

At the foot of the mountain, two soldiers with different armors were fighting desperately in the mud.

The soldiers on both sides roared and swung their weapons at each other. Their languages ​​were different, and their shouts were also different, but their faces all had expressions of anger.

There is no army formation, no rules, it is a chaotic battle, relying on only one's blood.

These soldiers were neither the Ming army nor the Han army.

They are the armies of Fuyu and Yilou.

The two countries of Yilou and Fuyu are about the same size on paper, but in reality they are far apart.

Fuyu State occupies a relatively fertile plain area, while Yilou State's land, except for the plain and hilly area in the north, is mostly high mountains, named Dandan Daling (Changbai Mountain).

There are many tribes living in the Daling area. Although it is the territory of the Yilou Kingdom and they speak the same language, the tribal people in Daling have a high degree of autonomy.

Yilou Kingdom built a lot of cities in the gentle area in the northwest of Dandan Daling, but they called them cities, that's all they called them.

In Gongsun Du's eyes, the so-called "cities" built by both Fuyu and Yilou were not as strong as the camps built by the Han army.

Yilou's national power is much weaker than Fuyu's.

It's just that although Yilou's national strength is weak, the reason why it can still hold its territory is largely due to the advantages of the mountainous area.

If Fuyu country wants to attack Yilou country, there are only two ways to go.

The country of Yilou only needs to stick to two key points to keep the country safe from worries.

One is a relatively gentle road in the south. Although it is gentle, it is only gentle compared to Daling alone.

The second road is to go east along the Nanshui (lower reaches of the Songhua River) waterway in the north. This road is relatively more suitable for attack.

Fuyu State attacked Yilou State, basically choosing this path.

But because of this, Yilou country set up a heavy defense on the road this time.

At the beginning, Gongsun Du also led the army of Fuyu Kingdom to attack Yilou Kingdom along the river.

Then the result was that Pingbai spent more than half a year in the air by the Nanshui River, and there was no way to overcome the defenses set up by Yilou Kingdom.

To describe the fighting power of Fuyu's army as weak is an insult to weakness...

He finally understood why Wei Qiutai was willing to take the initiative to become a vassal.

The state of Fuyu's army can no longer be described as unbearable, it can be directly described as appalling.

Although the march is slow, it can maintain a certain formation at any rate. Before the battle with the enemy, the army formation can be regarded as somewhat decent, but once the battle is fought, it is completely out of order.

The same is true for the army of the Yilou Kingdom. To be precise, it should be even more unbearable. After all, the army of the Fuyu Kingdom still had a little shadow of an army before the battle, and the chaos of the Yilou Kingdom was like the grass bandits that Gongsun Du had seen before bandit.

To say they are an army is to flatter them.

The fighting between the two countries was not even as orderly as the fighting between Liangting Townships in the Han Dynasty for water.

Gongsun Du held the horsewhip in his hand, and looked at the chaotic armies on both sides of the mountain road, the veins on his forehead kept beating.

Even the fights in the two Ting townships in the Han area were quite organized. Although they were not arranged in an army formation, they knew how to cooperate, had a certain formation, and even seized high ground and outflanked them.

No wonder it was only heard that Goguryeo had harassed Lelang County, but not Fuyu State harassed Xuantu County.

Weiqiutai is old after all, and Fuyu's army even maintained a certain advantage against Goguryeo.

When accepting the canonization of the Han Dynasty, Fuyu Kingdom was still the overlord of the Liaodong area.

But time has passed, and because of the protection of the Han court, Fuyu's military equipment has become more and more relaxed.

Born in sorrow, died in peace, this is exactly the current situation in Fuyu country.

The regular army of Yilou Kingdom is all armed with long spears. Although there are almost no iron spears, the victory lies in unity.

But there were many unkempt soldiers in furs, and their weapons were crude, and some even carried stone tools and bone clubs.

When Gongsun Du saw these soldiers, the first word that popped up in his mind was actually "savage".

Although these savages were extremely poorly equipped and unable to fight battle formations, they were extremely brave.

Although Fuyu's attacking army is large in number, it is actually in a suppressed position.

Jian Wei followed behind Gongsun Du, and her expression was extremely embarrassing.

Compared with the neatly arranged Ming army, the army under him is not even worthy of being called an army.

Gongsun Du calmed down, then turned his head to look at Jane.

When he turned his head, his expression had returned to normal.

"If this battle is won, the capital of Yilou Kingdom will be exposed to our army and our soldiers."

"But it can't be delayed for too long. The news of our army's attack on the mountain road should have spread. If our army can't defeat the enemy in time, once the main force of the Yilou Kingdom returns to the army, the battle may be prolonged, which is extremely detrimental to our army."

"After going out for many days, the money and food wasted a lot, and our army has no strength to fight anymore."

"The son of the country should have received news from the country, right?"

Jian Wei looked embarrassed, and what Gongsun Du said made him more anxious.

The country was in turmoil, and his father, Wei Choutai, was seriously ill this time, and it seemed that he could not recover at all.

He is leading the army abroad, but there is an undercurrent in the country. Several of his brothers are secretly plotting to compete with him for the position of the leader of Fuyu Kingdom.

Gongsun Du narrowed his eyes slightly, and Jane's joy, anger, and sorrow were all on the surface, and it was easy to see what was going on in his heart, and there were not many cities.

The current status of the son of the country and the prestige in Buyeo are all due to the small victories in the previous wars against Goguryeo and Yilou.

Wei Qiutai has lived for too long, and several of his sons have died.

In the first year of Yongning (120), Fuyu was attached to the Han Dynasty. At that time, he was still very young. As his heir, Wei Qiutai followed the envoy team to Luoyang to pay tribute with gifts.

At that time, the emperor of the Han court was still Emperor Han'an.

Emperor Han'an bestowed a golden color on Wei Qiutai's seal and ribbon, and accepted Fuyu.

Since then, Fuyu Kingdom has become one of the vassals of the Han court, and has also been included in the scope of protection by the Han court.

The protection of the Han court is a gold medal for a small country. In the entire East, few countries dare to challenge the majesty of the Han Empire.

Today, Weiqiutai has ruled Buyeo for more than [-] years.

Now his life has come to an end, and he has ruled Buyeo for too long.

"I heard something about the team transporting the luggage in Buyeo, and I also know something about the situation in your country."
