"Hahaha, I don't dare!" Lin Feng laughed wildly, uninhibited, and did not have the slightest pre-war phobia.

Or rather, he hides his fear very well. "You will see that the 300,000 cavalry of the Rong clan were killed by me, how the Murong family disappeared on the grassland, and when the Rong clan is destroyed, you will stay and serve me with all your heart, and when the time comes, if you ask me, I will give you a way to live."

"Foolish dreams, arrogant, my Rong cavalry is invincible, you are also worthy of my father's shoes, if you go north, the Rong warriors will let you go and never return."

"Invincible, hehe, the princess is so forgetful, who is losing the land north of the royal court, and who is losing cattle, sheep and horses, don't say that the Rong people have no food and grass, even if I am defeated, princess, do you think I will spare you easily? Like this country-like and fragrant woman, before she died, she lived happily for a few days, wouldn't she be violent and ruined. ”

"Shameless!" Murong Mengfei gritted her teeth, like gravel, creaking in her mouth.

"I'm shameless, I treat you sincerely, you never appreciate my goodness, do you have persecution paranoia, that's it, I follow your wishes today?" Lin Feng had a long mouth, pointed to his teeth, and said cheaply.

"You-you-you!"

Seeing Murong Mengfei's angry appearance, Lin Feng felt very happy in his heart, finally dissipated the sulkness in his heart, got up and laughed, and walked away.

That night, 50,000 dragoons were raised, and Lin Feng and his party disappeared in Beidaying, and along with 30,000 inferior horses and ploughing cattle.

Black Flag Pass, the natural barrier of the northern part of the Yan Kingdom to resist the Rong people, and the Wolf Pass, the White Horse Pass, and the three major male passes.

It is located in the northernmost part of the Yan Kingdom, bordering the Rong people. The black flag pass is surrounded by mountains on both sides, the front of the pass forms five or six miles of mountain road, out of the pass ten miles, it is an endless grassland, easy to defend and difficult to attack, there is a big man when the pass is not open.

For hundreds of years, it has been the forefront of the Yan Kingdom's resistance to the Rong people, but it is a pity that it was taken away by the Rong people twenty years ago. Lin Feng returned from the battle outside the fortress and recaptured the Black Flag Pass, and sent Liu Xuanyuan, a famous general of the Yan Kingdom, to guard it.

As a general guarding the customs, Liu Xuanyuan deeply understands the importance of geographical location to Yan Guodi. After taking over the Black Flag Pass, the first thing he did was to order the soldiers to destroy the mountain stream path to prevent the news from being learned by the Rong people and taking the opportunity to enter the pass.

Began to guard the Black Flag Pass, Liu Xuanyuan ordered to rebuild and strengthen the Black Flag Pass, on the mountain road outside the pass, arranged many trap pits, stumbling horses, mountain streams, and stored a lot of boulders in advance to deal with the attack of the Rong people.

During this period, Liu Xuanyuan recruited new soldiers to appease the people who returned to Black Flag Pass, and everything was in order.

After many years of dealing with the Rong people, Liu Xuanyuan understands the temperament of the Rong people, knows that the other party is arrogant and arrogant, and flaws must be reported, and he has never put Yan Guo in his eyes. This time, he suffered a defeat at the hands of the Emperor of Yan, and he will definitely take revenge.

At the end of June, Liu Xuanyuan repaired the city wall of Heiqiguan and sent scattered horsemen to pay close attention to the Rong people near Heiqiguan, but there was no trace of the Rong people within a radius of 100 miles of Heiqiguan.

Liu Xuanyuan was puzzled, and continued to send scattered horsemen deep into the grassland, and in the end, dozens of scattered horsemen were dispatched, and none of them came back.

After careful consideration, Liu Xuanyuan stopped reconnoitring in the depths of the grassland, and sent scattered horsemen to monitor the movements around the Black Flag Pass, clamping and arranging defenses. Because, he had a hunch that the Rong people had not forgotten to take revenge on the Yan Kingdom, and if they didn't come, they would be imposing.

At the beginning of October, the temperature at Heiqiguan began to plummet, the water froze, and the gale eroded the bones. At this moment, there are no Rong people, Liu Xuanyuan According to the experience of previous years, the Rong people will not go south this season, so he secretly breathed a sigh of relief. In the past ten days, except for daily training, the casual rider has rarely gone out.

However, the Rong people still came, on a cold and fierce morning, appeared on the plain ten miles away from the Black Flag Pass, Liu Xuanyuan, who had just relaxed, immediately tightened the strings in his mind, and the 300,000 cavalry of the Rong tribe went south!

Rao is Liu Xuanyuan racked his brains, and he couldn't guess what the Rong people's intentions were, so he hurriedly gathered soldiers, stuck to the mountain road, and fought to the death with the Rong people on the mountain road five or six miles outside the pass.

Soon, news came from outside the Black Flag Pass, the people who had not had time to enter the pass were all slaughtered overnight, and the next day, the 100,000 cavalry on the left flank, after spending 5,000 wounded, finally came to the city and launched a fierce attack on the Black Flag Pass.

Knowing that the 40,000 tiger and leopard battalion was difficult to stop the Rong people's soldiers, when the Rong cavalry appeared, Liu Xuanyuan sent people to the imperial court for help.

However, the Rong people relied on their strong soldiers, attacked repeatedly, fought hard day and night, the tiger and leopard battalion suffered seven or eight thousand casualties, the number of arrows dropped sharply, and the rolling wood and stones were almost consumed.

The Rong people charged in waves, and the soldiers of the tiger and leopard battalion fell one by one, and on the head of the city, before the corpses could be carried down, some people fell.

After two days and nights of hard fighting, more than half of the casualties of the tiger and leopard battalion were exhausted, and the soldiers were exhausted without rest for several days and nights.

On the third day, at dusk, the cold wind was stronger, whistling on the mountain road, like a ghost howling, the Rong people temporarily stopped the attack, tens of thousands of people gathered on the various hills, and the cavalry on the mountain road was pushed to both sides, as if they had taken a short rest, ready to start a new round of attacks.

The black flag closed and the blood froze into ice slag, one by one, weirdly enchanting in the remnant sun. Two days and three nights of fierce fighting, tired of many people. Liu Xuanyuan threw away his tattered cloak and sat on the ground, leaning against the city wall and breathing heavily. The young face was stained with blood, his lips were already chapped under the cold wind, and the black chain mail on his body, blood and sweat mixed together, all frozen, stuck to the chain mail. Liu Xuanyuan looked up at the south with a complicated expression.

"General, the Zhaorong people are attacking day and night, I'm afraid we won't be able to hold out until reinforcements arrive. Besides, besides, I'm afraid that there are no soldiers to be afraid of in the capital. A big beard, filtering out the ice slag on his beard, his eyes were empty, and he walked towards Liu Xuan.

After two days and three nights of hard fighting, the soldiers never rested, and the casualties were extremely heavy, but it also caused a lot of trouble to the Rong people, and at least more than 30,000 people died under the Black Flag Pass.

However, 30,000 versus 300,000 did not affect the morale of the Rong people at all, and the 40,000 people in the Black Flag Pass, more than half of the casualties, the logistics were seriously insufficient, and the soldiers were extremely tired, and continuing to fight would only increase the casualties and could not change the situation in which the Black Flag Pass was broken.

Liu Xuanyuan took out a few pieces of jerky in his arms, distributed them to the bearded man, stuffed the rest of the land into his mouth, and said while chewing: "I also know that the capital can't send many reinforcements, but the emperor has the grace of knowing me, even if the blood-stained territory is the field, I will not take half a step back." ”

The news has been out for nearly three days, if there are reinforcements in the imperial court, I am afraid that they will arrive early, and if the reinforcements do not arrive for a long time, the emperor must have no idea.

Swallowing the jerky that was difficult to swallow, Liu Xuanyuan glanced at the Rong cavalry outside through the battlements of the city wall, and suddenly, his eyes increased, and he stood up and looked into the distance. "It's not good, when will the Rong people have siege equipment in the Song Kingdom."

At this moment, I saw that the soldiers of the Dirong tribe on the mountain road were pushing ladder trucks, stone throwers, siege vehicles, and crossbow cars, and were rapidly approaching the Black Flag Pass.

"Mother, that woman in the Song Kingdom, colluded with the Rong people to plot against my Dayan." Li Kui's palm slammed on the battlements of the city wall, and said resentfully.

The Song State, one of the ten major vassal states, is not very strong, but there is a 100,000-strong mechanical army, fighting in the south and the north, close to the Jin State Huben, and the Xuanjia soldiers of the Chu State are all defeated in front of the other party. Five years ago, Zheng Guo's soldiers went through the horses, thought that the change was successful, sent 150,000 heavy cavalry to attack the Song State, the first battle of the successive battles, annexed the two state capitals in the west of the Song State, at this time, 30,000 mechanical soldiers went to war, a war annihilated the Zheng State heavy cavalry, none of them lived, since then, the mechanical soldiers are famous all over the world.

At this time, seeing the siege vehicles and ladder vehicles on the heights of dozens of meters, it is no wonder that Liu Xuanyuan's complexion changed suddenly, and Li Kui scolded his mother angrily.

"Li Kui, hurry up and take 5,000 brothers and transfer the people in the city, otherwise, it will be too late." Liu Xuanyuan clenched the war knife in his hand tightly, looked at the siege equipment outside close to the ground, almost roared out, and said to Li Kui: "Hurry up, I will buy time, the bow and arrow are gone, the stones are gone, the stones are gone, and the houses in the gate can be blocked for a day, and it can be a moment for a moment." ”

"General, no! You are a famous general of Dayan, if you are gone, our Dayan will also be gone! Realizing that Liu Xuanyuan was ready to live and die with Black Flag Pass, Li Kui grabbed Liu Xuanyuan's arm and said sadly.

"Hurry up, there is no Black Flag Pass, there is still Wolf Pass, there is also Tumu Fort, and White Horse Pass. If you don't leave, the Black Flag Pass will be broken, and you can afford the lives of tens of thousands of people? Liu Xuanyuan's voice was low, like an angry leopard. He did not fight with the mechanical soldiers of the Song State, but the mechanical soldiers killed 150,000 Zheng Guo's iron cavalry and defeated the 90,000 Xuanjia soldiers of the Chu State, and almost the two most powerful infantry cavalry in the world were defeated in his hands.

Although there are not many siege equipment of the Rong people in front of them, and they are not operated by the Song people, the powerful mechanical power is famous, and they are all siege weapons. Liu Xuanyuan didn't dare to delay in the slightest, tens of thousands of people's lives, he couldn't afford it.

Li Kui looked up at the approaching mechanical soldiers in the distance, and Liu Xuanyuan roared again: "Go, go!" ”

"General, you wait, the last general will definitely return! Death is also with you! Li Kui let go of Liu Xuanyuan's arm, grabbed the big knife leaning against the city wall, took a breath of cold air, felt uncomfortable in his heart, turned around and ran down the city wall. After a while, Li Kui ran back and said excitedly: "General, reinforcements, reinforcements have arrived!" ”

"What, reinforcements, how many?" Liu Xuanyuan got up from the city wall, excited and unbelievable.

"Listening to the young general, it seems that there are more than 30,000 people, crossbowmen, and heavy cavalry! A lot of ordnance was also brought in. In addition, 40,000 light cavalry entered the grassland along the wasteland bordering the Jin Kingdom, and estimated that they had reached the rear of the Rong people at this moment. ”
