Yanjun Yiwuchang Mountain, this is a mountain range that almost separates Yanjun into two, this mountain range itself is not long, north-south direction, the mountain is only more than 100 miles, but because Yanjun itself is narrow, it is particularly prominent.

In the northern section of Yiwuchang Mountain, it is an endless mountain pasture, which was once the horse breeding place of the Sui army in the Goryeo Campaign, the horse farm is dozens of miles in radius, although many years have passed in the war, but the traces of the horse farm can still be found, some railings are still faintly visible, most of the railings are taken home by the locals as firewood to burn.

The high ground is a gray mountain rock craggy and bare, and from the mountainside there is a large forest, with pine and cypress, thick greenery, along the mountain range, the forest stretches for hundreds of miles like a green belt wraps around the high mountain.

Early in the morning, a group of about fifty cavalry rushed out of the forest and rushed eastward, this was a group of Sui scouts equipped with two horses, galloping knights all dressed in armor, black and shining, and moving quickly.

Their horses were tall and strong, with well-proportioned limbs, shiny brown horses, long tails fluttering in the wind, and high necks covered with brushed manes.

The cavalry and their horses complemented each other, all of them were tall and burly, with long hands and feet, black thick hair fluttering under the eagle helmet, grim expressions, sharp eyes, jujube wood spears in their hands, cowhide riding shields and bows and arrows on their backs, horizontal knives stuck in their belts, and shiny armor was very strong.

Fifty horsemen marched in a double column, followed by their other horse, carrying their blankets and rations, and the chief lieutenant was young and valiant, only sixteen or seventeen years old. There was a mature glow in his bright eyes that didn't match his age.

The captain is Xiao Yannian, he holds the phoenix wings and gold pistol made for him by his father, and rides an extremely majestic white war horse, this war horse is a tribute to the imperial court in the Western Regions, and was rewarded by Yang Guang to his father Yuwen Chengdu, and even a piece of his armor was left to him by his father.

Although Xiao Yannian is full of his father's brand, it is only his remembrance of his father. He didn't get arrogant because of his father.

On the contrary, he kept a low profile, and none of his fifty men knew that he was the son of Yuwen Chengdu, the general of the Sui Dynasty's Left Guard. However, he served as a lieutenant at such a young age, which still made some veterans dissatisfied, which did not conform to the Sui army's practice of promoting with military merits.

The cavalry marched for more than two hours. Gradually slowed down, there was a dense forest in front of him, Xiao Yannian pointed with a whip, "Go to the forest to rest!" ”

The horsemen turned their horses' heads, crossed a stream, and rushed into the forest, which covered hundreds of acres, deep and quiet, with all kinds of colorful flowers growing on the ground, and white fungi scattered at the roots. It can be seen that there is no sign of people here.

The soldiers dismounted one after another and sat down on the grass, and a dozen soldiers took gourds and buckets to fetch water from the stream outside, and the war horses leisurely gnawed on the grass on the grass.

Xiao Yannian sat next to a flat boulder and looked at the map. His serious gaze resembles that of his father, and his tall nose shows the noble blood of his nobles of the Southern Dynasty.

This time, he was ordered by Luo Shixin to investigate the movements of the Goryeo army, and he quickly found his current position on the map, and drew a circle on the map with a piece of charcoal, which was located twenty miles north of Huaiyuan Town, and ten miles east of the Liao River.

He had been patrolling the area for almost seven days. There was still no trace of the Goryeo army, but a Yan army of thousands of people was found the day before yesterday.

'Do you want to cross the Liao River?' Xiao Yannian thought secretly.

At this time, a team member came up to him and said with a smile: "Captain, it's better to find a village, some to eat, some to drink, and to inquire about the news." ”

Xiao Yannian glanced at him, "This is the territory of Gao Kaidao, let's not be too public, otherwise we will be told by the villagers, and we won't know how to die, and more importantly, we will miss the general's big event." ”

"But will there really be a Goryeo army?"

The team hesitated for a moment, and finally couldn't help but say: "The brothers all said that it is unlikely that we will encounter the Goryeo army, we have been patrolling Yanjun for seven days, if we can meet it, we should have met it a long time ago, we all think that even if we look for ten days, there will be no news, it is better to ...... Why don't you just go home, right? ”

Xiao Yannian snorted coldly and said, "When it should end, I naturally know in my heart, I don't need you to remind me!" ”

Team Zheng looked very embarrassed, so he had to laugh dryly, "The humble position is just a casual talk, of course it is the captain's decision." ”

The team retreated, sat down against the roots, and scolded in a low voice, and several veterans immediately surrounded them and asked in a low voice: "What do you say, does the captain still want to continue his patrol?" ”

"Get out of the way!"

The team scolded, "It's all you bastards who are troublesome, and Lao Tzu is being disciplined." ”

Several veterans refused to leave, gathered around the team, and talked about it: "Who is this captain, he became a captain for some reason, what is his background?" ”

"Who knows? It is estimated that the origin is not small, I heard that the governor inspected Hedong County and specially compared arrows with him, and his surname is Xiao, I estimate that he is a nobleman of Xiliang. ”

Team Zheng sighed, "No matter who it is, one thing is for sure, he will be promoted faster than us, anyway, when you are the team leader, he is at least already a general, so the best way is to be honest and obedient, don't provoke him." ”

The veterans were puzzled, but they had to listen to the words of the team, and at this moment, the soldiers on the top of the big tree shouted: "There are several cavalry running towards us!" ”

All the soldiers jumped up one after another, and Xiao Yannian shouted: "Don't panic, retreat into the depths of the forest!" ”

The soldiers quickly packed up their things, led the horses, and retreated into the depths of the forest, and Xiao Yannian led a dozen scouts to ambush in the nearby trees.

In a moment, three cavalrymen rushed into the forest, all of them were soldiers of Gao Kaidao, and as soon as they entered the forest, one of them scolded, "Call Lao Tzu like a dog, Lao Tzu is gone, shit Goryeo people, they have the ability to send their own people to deliver letters." ”

At this time, another soldier suddenly noticed the anomaly, "No, there are people here who have been here, and cavalry have been here." ”

They found the horse's hooves and the dung of the horses, and the three Yan army spies immediately realized that something was wrong, and turned to run out of the forest, at this moment, several arrows whizzed, all of them hit their legs, and the three of them fell to the ground screaming, and a dozen Sui scouts jumped down from the trees and resisted them with their spears.

"Spare your life!"

The Yan army spies shouted loudly in horror, Xiao Yannian stepped forward quickly, grabbed one person's hair, dragged him under a big tree, squatted down and asked, "Where is the Goryeo army?" ”

The spy was so frightened that he couldn't say a word, Xiao Yannian took out a dagger and pressed it against his throat, "Say it quickly, otherwise I will kill you with a knife." ”

"In ..... The east bank of the Liao River! The spy said in a trembling voice.

"How many troops are there, when will they cross the Liao River, and who will be the main general?"

Xiao Yannian asked a series of questions...... The Liao River, which was the boundary river between Goryeo and the Great Sui, was also the first step of the Goryeo War, and was the forward position of the Great Sui to attack Goryeo, although the war has been over for many years, there are still no people living on both sides of the Liao River, there have been too many people who have died here, and the land is full of the breath of death.

On the banks of the Liaodong River, the city occupied by hundreds of thousands of Sui soldiers has been reoccupied by the Goryeo, and now a Liaoshui can no longer stop the ambition of the Goryeo, and they took advantage of the opportunity of the surrender of Gaokaido to begin to expand westward.

The width of the Liao River is about dozens of zhang, the water depth is flat, at this time two pontoon bridges have been erected on the Liao River, a group of Goryeo soldiers are quickly crossing the pontoon bridge, marching to the west bank of the river, on the east bank of the river, tens of thousands of troops are densely arranged, the momentum is huge.

Although Gai Suwen and Gao Kaidao's negotiation was to send 30,000 troops, when the final decision was made, the Goryeo Prime Minister Yuan Taezuo, who held the military and political power, changed his mind, and he thought that it would be difficult for the 30,000 army to defeat the Sui army, so he decided to send 50,000 troops, led by him personally, to meet the Sui army.

On the bank of the Liao River, Yuan Taizuo looked at the Liao River with a cold gaze, just by this river, six years ago, the Sui army launched a large-scale attack on Goryeo, three battles in a row, almost destroyed the foundation of Goryeo, and now six years later, it is the other way around, it is his Goryeo army that attacks the Sui Dynasty, no! It was an attack on the Central Plains.

Yuan Taizuo has been waiting for this moment for a long time, this has always been his dream, he is sixty years old this year, he thought that he would no longer have a chance in this life, but he did not expect that in his twilight years, this moment would become true, his heart was extremely excited, so that he decided to personally lead the army to the west to fulfill his long-cherished wish for decades.

"Father!"

The eldest son, Gai Suwen, galloped in from afar, this time the Goryeo army went west, he did not accompany the army, but stayed in Goryeo, taking charge of the military and political affairs for his father, and he specially rushed to the Liao River to see off his father.

"When is my father going to return from this expedition to the west?" Gai Suwen asked worriedly.

"I don't know, it's two months at the earliest, or half a year at the latest."

Yuan Taizuo trusted his eldest son very much, he personally led the army to the west, and handed over all the military and political power in his hands to him, he smiled and patted his son's shoulder, "You are already thirty years old, with your intelligence, I believe that you can shoulder this burden, King Rongliu has just succeeded to the throne, he has no prestige yet, as long as you firmly grasp the power, he will have nothing to do with you." ”

"Please rest assured that I will definitely handle the affairs of internal affairs, and I hope that my father can realize his long-cherished wish as soon as possible."

Yuan Taizuo looked up and smiled, "Yes! Thinking that my long-cherished wish for decades is about to come true, even if I die, I will be blind, and I will send you good news in Youzhou City. ”

Yuan Taizuo looked at the wide water, and he gave an order in high spirits: "Wear my order, and the army will speed up and cross the river...... In a dense forest on the other side of the river, Xiao Yannian was leading fifty scouts to closely watch the Goryeo army cross the river, and the news of the Yan army's spies confirmed that at least 50,000 Goryeo troops had crossed the Liao River to help Gao Kaidao......
