Several soldiers led Du Yuanshan up, and Du Yuanshan was extremely grateful. If Li Zhen had not led the cavalry to arrive in time, they would have wiped out the entire army today. He knelt down on one knee and bowed to Li Zhen with his fists, "I'm going down to Du Yuanshan, thank General Li for his great support!"

Li Zhen quickly helped him up, "General Du doesn't have to be too polite. It's our duty to lead the army to rescue him. I just hope that the rescue can be timely and the Tang army will not suffer too much."

Du Yuanshan sighed, "When General Li arrived, the Tang army had suffered heavy casualties and was about to be defeated. I don't know how many casualties the Tang army was?"

Seeing that the sun had set and night was about to fall, Li Zhen said, "Check it out quickly and retreat! I am worried that the main Khitan forces will come back, after all, we don't have many troops and will suffer a great loss."

A word reminded Du Yuanshan, and he immediately ordered: "Rescue the wounded and retreat immediately!"

The Tang army had no time to have a clear battlefield, but only collected war horses and dry food left by the Khitan army. The war horses were used to consign injured Tang soldiers and dry food to supply the soldiers. More than 10,000 Tang soldiers quickly evacuated east under the escort of 5,000 cavalry.

Just as Li Zhen was worried, just over an hour after retreating west, Sun Wanrong led 20,000 Khitan cavalry to Yuyang County. At this time, Sun Wanrong had received an emergency report from Luoyang. The Tang Ting sent Lou Shide as the commander and had led a 100,000 army north. He was afraid that Luo Wu would be in trouble, so he led his army to support him.

But Sun Wanrong was still one step late. Luo Wu's entire unit had been defeated by the Tang army. Only less than 10,000 troops were left with tens of thousands of casualties. Even the chief general Luo Wuzhu was unfortunately killed. This was the biggest failure since Sun Wanrong's rise.

Sun Wanrong looked at the corpses everywhere, his fists slowly clenched, and gritted his teeth with hatred, "It's this Li Zhen again, I must kill him with my own hands!"

A ten thousand men whispered beside him: "They have been evacuated for only more than an hour. Why don't we catch up with them? Maybe we can catch up with them!"

Sun Wanrong shook his head, "This Tang army is not the main force, and we cannot focus our energy on them. The key is Lou Shide's main force Tang army. We must find a way to defeat him. As long as we defeat the main force of the Tang army, Hebei will belong to us."

At this time, Yi Yuanyu stepped forward and smiled and said, "I have a strategy to defeat the Tang army. I wonder if the chief is willing to adopt it?"

Sun Wanrong was excited. So far, all the strategies of Yi Yuanyu had been successful. Sun Wanrong almost obeyed him. He hurriedly said, "Please tell me, General!"

Yi Yuanyu whispered: "The biggest problem of the Tang army's 200,000 troops is supply. It can be said that supply is related to success or failure. If we lengthen the front line, there will inevitably be loopholes between the main force of the Tang army and the logistics supply. As long as we seize the opportunity and severely damage the logistics supply of the Tang army, the main force of the Tang army will be in chaos without fighting, and then the total annihilation of 200,000 people will be under our control."

Sun Wanrong was overjoyed and asked again: "How to lengthen the front line?"

Yi Yuanyu whispered a few words in his ear, and Sun Wanrong nodded slowly, Yi Yuanyu's plan came to his heart.

When it was almost dawn, the Tang army arrived at Yansai Fort, which was a fortress in Yanshan and was the only way to Yuguan. The terrain was dangerous, and the Tang army had 300 garrisons here.

Although 300 defenders could not resist the attack of the Khitan army, with tens of thousands of Tang troops, the significance of this Yansai Fort was extraordinary. They could rely on the danger of defending, and even if tens of thousands of Khitan troops came, they might not be able to capture Yansai Fort.

The Tang army then breathed a sigh of relief. They were already exhausted and they all rested and drank water and replenished dry food. Du Yuanshan found Li Zhen again and sighed: "I just counted it. There were still 12,000 soldiers. Yesterday, there were nearly 2,000 soldiers killed and more than 1,000 injured."

"But we won the final victory, didn't we?"

Li Zhen smiled and comforted him, "I have also roughly estimated that our two armies killed at least seven or eight thousand enemies and killed Luo Wuqian. At least we can ask for credit from the court."

Du Yuanshan understood Li Zhen's meaning. He wanted to count the credit on the two armies. Du Yuanshan was not embarrassed to accept this military merit that should not belong to him. He shook his head and said, "The credit last night belonged to the general. We were rescued by the general and would not be greedy for merit."

Li Zhen smiled, then changed the topic and said to Du Yuanshan: "There are about 120 miles from here to Yuguan. I plan to lead my army to Yuguan. The Yansai Fort will be handed over to General Du to guard it. There should be no problem!"

Du Yuanshan nodded, "I still have 12,000 brothers. There is no problem in guarding Yansai Fort, but I lack food. This is the biggest problem at present. I plan to build a grain transportation line from Yuguan to Yansai Fort first. I wonder if the general can leave some horses for me."

?"No problem!"

Li Zhen agreed readily: "I will leave all the three thousand war horses captured from the Khitan to the general, and the army will be killed in three or four days at the latest. General, please support it for a few more days."

Du Yuanshan nodded silently. He was still a little worried about the situation of the Tang army in Ji County. One hour later, Li Zhen's subordinates finished packing up, and more than 5,000 people turned over and rushed to the horse and rushed towards Yuguan...

Three more days passed, and Lou Shide led an army of 200,000 to Youzhou. At this time, the Khitan army had retreated to Miyun north, and the siege of Jixian County was finally resolved. Su Honghui personally went south to welcome Lou Shide's army.

Lou Shide's army was stationed on the north bank of the Sanggan River, about twenty miles south of Ji County. The army covered a thousand hectares of land, and thousands of large tents were invisible at a glance.

Su Honghui was led by several soldiers to the central army tent. Su Honghui was very nervous. He was responsible for Wang Xiaojie's death. He knew that the emperor would not spare him easily. It depends on how much he could atone for him to stop the Khitan army from moving south this time.

"Please, General Su! Lou Xiangguo is waiting in the big tent."

Su Honghui suppressed his inner tension and walked into the big tent quickly. He saw Lou Shide standing at the table and staring at the map without saying a word. He hurriedly stepped forward and knelt down on one knee, clasped his fists and said, "I am in charge of Lou Xiangguo!"

Lou Shide looked up at him and said coldly: "General Su please get up."

Su Honghui heard the coldness in Lou Shide's tone, and his face turned red and he quickly said in panic: "I am guilty of being humble!"

"You are indeed guilty, but I cannot decide your sin. You will explain to the Lord yourself. I am only concerned about how to defeat the Khitan. To what extent can you lose your merits? It's also here. Do you understand what I mean?"

Su Honghui was speechless. Of course, he understood Lou Shide's hint. After a while, he sighed and said, "I will do my best to assist the Prime Minister."

Lou Shide nodded, and the expression on his face eased a lot, "I want to know the situation of the Khitan army now, tell me."

Su Honghui felt a little calm and hurriedly said, "Report to the Prime Minister, the Khitan currently stationed troops in Miyun. According to reliable information, they have about 120,000 people. The food and grass of the Tang army they plundered from Zhaozhou can support them for more than half a year."

Lou Shide secretly scolded Wu Yizong's coward. The thousands of Khitan cavalry scared him to death, who had an army of 100,000. He lost all his food and supplies, and was even massacred by the Khitans. It was simply outrageous that such a scum general, the emperor, did not punish him for his crime.

Lou Shide was depressed and asked again: "How is the situation there in Yuguan?"

"The other side of Yu Pass is guarded by General Li, and 5,000 cavalry and 10,000 soldiers can be completely defended."

Lou Shide walked a few steps behind his hands. He felt that the Khitan seemed to be doing something unreasonable in some places, such as they retreated without plundering them. This was completely incompatible with the rules of Khitan doing things.

This is not because Sun Wanrong is kind, but because as a great chief, he must meet the requirements of various tribes to plunder money, otherwise he, the great chief, would not be able to continue to be regarded as a great chief.

Then there is only one explanation. The Khitan did not really withdraw his troops, but was luring himself to go north, trying to lengthen the front line, trying to defeat the 200,000 Tang troops in one fell swoop and seize Hebei again. After Sun Wanrong's ambush Wang Xiaojie, his ambition was already unstoppable.

At this time, Su Honghui whispered again: "Bizhi thinks that the Khitan army wants to lead the Tang army to the grassland outside the pass to fight to the decisive battle, so that their cavalry will have the advantage. The Khitan army has used a trick of luring troops several times, including the temptation of General Wang. This time it should be the same. If the prime minister underestimates the enemy, he will be deceived."

"Like the Tubo people, the Khitans are powerful nations with strong combat power. Compared with the Turks, their equipment is more excellent, especially plundering a large amount of Tang army equipment. This is a powerful force, and those who underestimate the enemy will be defeated."

"Don't the prime minister want to fight?"

"Not it!"

Lou Shide sneered and said, "Since that's the case, we will send troops to be gentle. I think who can survive whom?"

Just then, a noise came from outside. Lou Shide frowned and asked dissatisfiedly: "What's the noise?"

A personal soldier ran into the tent and reported urgently: "It's snowing in the prime minister."

Lou Shide quickly walked out of the tent, and saw heavy snow falling all over the sky. The sky in the distance had turned gray. This winter, the first heavy snow finally came...

The development of the battle often does not follow people's will. The winter of this year was particularly strange. It was not until late November that the north wind blew the first heavy snow, but soon, three consecutive blizzards followed one after another.

The blizzard raged for four days and four nights. When the snow stopped, the world had already become a snowy world. The snow in the wilderness reached three feet deep, production was all stopped, and the war was forced to stop.
