In November, it was already snowing heavily in the northeast.

The east coast of Yaluzha, Goguryeo Military Camp.

Yuan Gaisuwen patrols his carefully repaired camp and keeps saying hello to the soldiers beside him.

Before the Tang army arrived, he had already built three camps on the east bank of Yaluzha.

It is not unreasonable that Goguryeo became a headache for both the Sui and Tang dynasties.

In terms of terrain, Goguryeo has unique advantages, typical of high in the north and low in the south.

To put it more specifically, it can be seen that Goguryeo is divided into two parts, the north and the south.

The northern part of Goguryeo is full of complex mountains and forests, such as Xing'an Mountains and Changbai Mountains. They are gathered together, and the terrain is extremely complex.

However, the south of Goguryeo is the richest Han River basin in the three countries of Haidong. It is one of the few large plains in the mountains and hilly sea east, rich and fertile.

In front of this, there were mountains and forests as gateways, and in the back, there were plains to replenish them, giving them stable room for development.

It was also under this unique geographical advantage that Goguryeo defeated the strong with the weak, causing the arrogant millions of troops of the Sui Dynasty to abandon their armor.

This time, Yuan Gaisuwen obviously intends to use the same trick again.

Moreover, the east coast of Yaluzha was chosen as the first line of defense against the Tang army and the last one.

Yaluzha is the Yalu River in later generations. As long as you cross Yaluzha, you will soon enter the Han River Basin and reach Pyongyang City.

"Gugu!Gugu!"

A crisp chirping came from the sky.

Yuan Gaisuwen looked overjoyed, and pointed his finger into his mouth and blew a loud whistle.

A dark eagle fell from the sky and landed steadily on Yuan Gassuwen's arm.

Yuan Gaisuwen instructed his guards to melt the frozen meat and took off a small bamboo tube from the black hawk's feet.

There are many mountains in the northeast, and there are many eagles in the mountains.

Goguryeo belongs to a multi-ethnic country, with its people mainly 风, Fuyu people and Han people. However, as its strength continued to expand, it absorbed some of the Marine people, ancient Korean people and the three Koreans.

The marsh is the Jurchens of later generations, and they are best at falcon training eagles.

Yuan Gaisuwen took a fancy to Eagle's agility and alertness and specially trained the Xinying who sent intelligence.

From Liaodong to Yaluzha, the mountains and forests along the way are rugged and extremely difficult to walk, and it is not easy to convey messages. But for Xinying, it only takes a few days to go.

Let the Black Hawk climb on his shoulders, Yuan Gai Suwen freed up his hands to get the letter and read it. In the letter, Daoming failed in the night attack.

Yuan Gaisuwen sighed helplessly and didn't care much.

He had already seen the combat effectiveness of the Tang army. Compared with the Sui army in the past, it was more than one level of strength. It was not easy to defeat them in the field.

But seeing that the Liaodong Bridge was demolished according to the plan, I couldn't help laughing: "Okay, great. The Liaodong Bridge was destroyed, and the Tang army's food was delayed at least half a month."

The terrain in Liaodong is complex and can be regarded as a barren land.

When Cao Cao used Guo Jia's plan to conquer Liaodong, he was almost wiped out due to the harsh environment.

The big rivers that can be seen there are the Xiaoliao River, the tributary of the Liao River.

Only these two rivers could stop the Tang army's logistics. The Liaoshui Bridge was broken and half of the success was achieved.

"Da Mo Lizhi!"

Gao Huizhen poked his hands and came nearby, saying, "Tang army is now living a very comfortable life with oak charcoal. It is somewhat inconsistent with Damolizhi's plan!"

Yoon Gaisuwen clearly felt that Gao Hui was really not so friendly.

He was unhappy, but he didn't show it.

The former Goguryeo King Rongliu was quite stubborn. Because Goguryeo's military power was controlled by the Five Divisions, King Rongliu wanted to confiscate the military power, and his ministers planned to eliminate some powerful generals within Goguryeo. The first one to take action was Yongaisuwen.

Yuan Gaisuwen rebelled against the generals and took the lead in taking the initiative. This political counter-killing was negotiated with the Five Tribes.

Yoon Gaisuwen was honored by Yoon Gaisuwen, and then he made King Rongliu's nephew Gao Zang the king and regent, becoming the regent of Goguryeo.

The Wudu Nusaya ate meat in big mouthfuls and gained huge benefits from this political event.

The Five Tribes Notha were therefore bound to Yuen Gaisuwen.

Because of the unity of interests, they will naturally be divided according to interests.

The northern part of the Nursagao Yanshou parted ways with Yoon Gaisuwen because Yoon Gaisuwen gave up more than thirty cities west of Yaluzha.

The other few Notha were also very dissatisfied behind their backs. If the Tang army had not been too strong, they had made them feel the crisis of destroying their country and destroying their clans, and they had to obey Yuan Gaisuwen's orders.

The interior of Goguryeo has collapsed.

But the disharmonious attitude between each other has been revealed.

When Yoon Gaisuwen heard Gao Huizhen openly revealing his shortcomings, she could only endure her anger: this was really beyond his expectations.

Due to his plan, the Tang army could not withstand the cold cold in the Northeast, which was a major victory factor.

As a result, the Tang army camp on the other side was in full swing, with a bright charcoal fire at night, and looking at it from a distance, it felt like the heat wave was imminent.

The Tang army actually used local materials, cut down oak trees around, made earth kilns in the military camps, and made charcoal on the spot.

They lived in Northeast China for a lifetime and did not know that oak trees could be made into high-quality oak charcoal to keep warm for winter.

The situation seems to be the reverse.

The Tang army was in full swing, and they were trembling with cold. Although the people in Northeast China were resistant to cold, they would still be cold if they should be cold. The charcoal they used could not last long, especially at night, who would get up in the middle of the night and add charcoal and fire?

So they imitated each other and cut down oak trees to make charcoal.

As a result, the oak trees are hardwoods and do not have certain kiln making technology. Want to make charcoal?

A foolish dream.

After a lot of hard work, I made out charcoal that could burn out fire and emit black smoke, which made Yoon Gassuvin's nose crooked.

I can't, I can only get cold honestly.

Especially since both sides have no experience in fighting in winter, they do not have enough understanding of charcoal.

When Li Yuanai was making oak charcoal, he repeatedly explained the key to charcoal poisoning. However, Goguryeo did not have such experience and used a lot of ordinary charcoal, and many people were poisoned by charcoal.

Compared with the two, Goguryeo suffered a great loss.

Yeon Gaisuwen is currently suffering.

"Look!"

Yuan Gaisuwen proudly handed the letter to Gao Huizhen and said, "Don't be impatient, the winner is in our hands."

Gao Huizhen took the letter and looked carefully, and her face was very happy. Compared to being unsatisfied with Gai Suwen, resigning from the Tang army was the top priority.

"In this way, the Tang army was in danger of being out of food?"

"Yes!" Yuan Gai Suwen said resolutely: "Unless they can grow wings, there is no possibility of food and grass being delivered on time. When the Tang army has no food, it is time for us to attack..."

His eyes were hot, and he could not even win a small victory in this battle.

If you lose too much and give up too much, even if you win a small victory, you will still be questioned and your status will be insured.

Only a great victory and a vigorous victory can shock the uneasy factor that is no longer convinced and dissatisfied.
