However, it is said that after the Xiongnu fled to Mobei, they devoted themselves to recuperating and practicing riding and archery, and they did not commit a border for a long time. But from time to time, he sent envoys to Han to ask for peace. Later, the noble minister came to Han, suddenly died of illness in Chang'an, Emperor Wu ordered Lu Chongguo to wear 2,000 stone seals to send him to the funeral, and gave a legacy worth thousands of gold. After Lu Chongguo arrived at the Xiongnu, Shan Yu said that the nobleman was killed, but detained Lu Chongguo and did not let him go. On that day, more than ten people were detained by the Xiongnu, and the Han detained the Xiongnu envoys to each other.

Suddenly reported that Lu Chongguo had returned from the Huns and asked to see him. Call in now to ask about the situation. After the confiscation of the country, Fang omitted the facts of the Huns.

It turned out that the Xiongnu Er Shan died of illness in the reign of three years, and there was a son who was still young and could not inherit the throne. It was only a year before he died in Lihu again, and his younger brother succeeded him. And the Marquis of the Han Dynasty was afraid of the Han Dynasty sending troops to attack, so he said: "The son of Han Tianzi is my father-in-law, how dare I be a son to fight against the Han?" Saying that, the Han envoy Lu Chongguo and others were all released, and they were escorted and sent to ask for peace. Emperor Wu was very pleased when he heard this, and he also released the Xiongnu envoys left behind, sent Zhonglang to return Su Wuzhijie, and gave him a generous gift of money to repay his kindness.

Su Wu Ziqing, that is, the son of Su Jian, the former Marquis of Pingling. Su Jianzi and Zhao Xinzheng Hu were defeated, ransomed as a concubine, and later reverted to the acting county guard, and died of illness. The three Su Wu brothers, since they were young, have all taken their father's shadow as their husband, their younger brother Su Jia as the captain of Fengche, their younger brother Su Xian as the captain of the cavalry, and Su Wu as the supervisor of the stable. At that time, Li Guang's grandson Li Ling was the Jianzhang supervisor, and Su Wu was the same servant, and the two had a close friendship. Su Wu was ordered to make it difficult to predict the good fortune this time, and said goodbye to his mother, wife, relatives and friends, and Li Ling also came to say goodbye when he heard it, and wrote three poems to give away.

Su Wu and the deputy envoy Zhonglang left Chang'an and more than 100 soldiers from Chang'an all the way north, and went to the Xiongnu to see Shan Yu, conveyed Emperor Wu's words, returned the Xiongnu envoy, and sent the money to the suspicious Hou Shan Yu. Shan Yu had no intention of making peace with the Han, but because the people who first ascended the throne were undecided, and because the Han envoys refused to surrender, it was useless to stay in the country, so it was better to return it, so as to delay the army. Seeing that Emperor Wu gave a generous gift, he became more and more proud, and was about to send someone to send Su Wu back to China, but who knew that an accident suddenly happened.

It turned out that Wei Lusu was friendly with Li Yannian, and Li Yannian recommended him to Emperor Wu, and Emperor Wu sent him to envoy to the Xiongnu. At the right time when Li Yannian was imprisoned for his crime, Wei Lu did not dare to return to China and surrendered to the Huns. Shan Yuyi was particularly favored by Wei Lu and named him the king of Ding Ling. His subordinate Yu often sent envoys from Weilu, unwilling to surrender to Hu, and consulted with the king of Mi, and the two discussed for a long time, but they did not get the opportunity. This time Su Wu arrived, Yu Changqian met the deputy envoy Zhang Sheng when he was in China, and said to Zhang Shengmi: "I heard that the Son of Heaven of the Han Dynasty was very resentful of Wei Law, I can kill him for the Han, and my mother and brother will be rewarded by the Son of Heaven in Han." Zhang Sheng immediately allowed it and gave Yu Chang a gift of property. Yu often prepares for himself.

More than a month later, Shan Yu went out hunting, and only the Yan family and Shan Yu's children were there. Before Yu Chang and more than 70 people got up, one of them escaped at night and exposed their plan. Shan Yu's disciples fought with them, and the king was killed in battle, and Yu was often captured. And when the Marquis heard about it, he returned and ordered Wei Lu to strictly interrogate the case. Zhang Sheng told Su Wu in detail, and Su Wu was stunned and said: "How can you avoid being tired after the matter has come to this?" If I am against the court, will I not be an insult to the country? It's better to kill yourself early! Then he drew his saber and wanted to kill himself. Zhang Sheng and Chang Hui hurriedly stepped forward to stop them, but Su Wu was persuaded by everyone not to do anything, and he decided to die in his heart. Zhang Sheng and the others were worried about each other's ghosts, but Wang Yu often did not confess the matter, so they could be safe.

Who knew that Yu Chang was severely tortured by Wei Lu, and the pain was unbearable, so he had to confess according to the truth. Wei Lu informed Shan Yu of the confession, and Shan Yu summoned your ministers to discuss the killing of the Han envoy. Zuo Yizhi dissuaded: "If he plots to kill Shan Yu, it is only a crime and a death penalty, and it is not here today, it is better to pardon him and force him to surrender." "Shan Yu summoned the Han envoy and his servants came to obey the order. Su Wu went to the palace when he heard the summons; Zhang Sheng and Chang Hui also followed angrily.

Wei Lu was ordered to surrender immediately. Su Wu listened and said to Chang Hui and the others: "If I surrender to the Xiongnu and humiliate me, what will I do in the future?" With that, he drew his sword and stabbed himself. In the congregation, the congregation was shocked, and Wei Lu took him by the hands and ordered him to ride to summon the doctor. After a while, the doctor arrived, and Su Wu fainted and bled profusely. The doctor dug a pit on the ground and set it on fire, and put Su Wu's reverse side on the pit, causing people to bleed by stepping on their backs. Then apply the medicine to the wound. It's also Su Wu's life that doesn't deserve to die, and heals for half a day.

Shan Yu respected Su Wu's festival and sent people to the camp to greet him in the morning and evening, and only took Zhang Sheng into prison. Soon Su Wu's scars gradually subsided, and Shan Yu repeatedly sent people to persuade him to surrender, but Su Wu just refused.

Yu Chang was sentenced to death, and on the day of the execution, Wei Lu wanted to use this to intimidate Su Wu, so he lined up to invite Su Wu, and raised Zhang Sheng and Yu Chang from prison. Wei Lu beheaded Yu Chang first, and said to Zhang Sheng: "The Han envoy Zhang Sheng murdered a close minister, and the crime should also be killed, if you are willing to surrender, you can be spared!" After speaking, he raised his sword and wanted to cut Zhang Sheng. Zhang Sheng hurriedly claimed that he was willing to surrender. Wei Lu recalled Su Wudao: "The deputy envoy should sit in a row if he is guilty." Su Wu Zhengse said: "I am not an accomplice, and I am not a relative, why do you sit together?" Wei Lu assigned the sword to Su Wu, but Su Wu still did not move. Wei Lu saw that Su Wuquan was useless to scare him without fear of death, so he said softly: "Why should Mr. Su be stubborn. I think I was also a messenger of the Han Dynasty back then, and I died in the Xiongnu because of something, and I didn't want to be favored by Shan Yu, not only was I crowned the king, but also had tens of thousands of people, and there were countless cattle, horses, and livestock. If Mr. Su is willing to come down today, he will be as rich as me tomorrow. Otherwise, you will use your body as fertilizer for weeds, and who will remember you? ”

Su Wu still didn't react. Wei Lu was anxious, and continued to throw out the bait bag and said, "If Mr. surrenders today, I am willing to be a brother with you." If you don't listen to my advice, it won't be so easy to see me again in the future. ”

Listening to Wei Lu's words, the more out of tune he became, Su Wu couldn't help but scold: "You are really a vain minister." How could the Han family treat you poorly, you couldn't bear to turn your back on your father. What do I see you doing when I see you being a servant like you? I'm sure I'm not going to surrender today, so please kill me. ”

Wei Lu was ashamed when he heard this, so he had to return the favor. After hearing this, Shan Yu admired Su Wu even more, and wanted to make him submit more and more.

So Shan Yu wanted to torture Su Wu and make it unbearable and had to surrender. So he sent Su Wu to be placed in a no-man's land on the North Sea, and asked him to shepherd the lamb and said, "The lamb must give birth to a child before it can be released." "The peony sheep does not give birth. He also placed his official subordinates and Chang Hui in other places so that they could not see each other.

Su Wu then held an envoy in one hand and a sheep whip in the other, and became a shepherd in this inaccessible and bitter cold place.

Su Wu had no one to supply food in Beihai, so he had to do it himself. He quickly mastered some of Robinson's skills, such as digging vole nests and discovering the fruits they had collected.

In order to remind himself not to forget his original intention and keep his mission in mind, Su Wu held the envoy tightly in his hand no matter how he lived. After a long time, the yak hair on the envoy had fallen off, and Su Wu still refused to let go.

Unconsciously, after five or six times of cold and summer, Su Wu thought that he might be dying of old age, and there was no hope of surviving here.

Who knew that one day I saw a large group of people coming from afar, Su Wu had not seen anyone for a long time, and now he had to meet, no matter whether it was Hu or Han, he felt happy in his heart. When he approached, it was Shan Yu's brother Yu Jingwang, who heard that there were many birds and beasts in the North Sea, so he led the crowd to shoot and hunt. When I saw Su Wu, I knew that he was the one who did not surrender to the Han Dynasty. Although Su Wu could not hide his old age, his eyes were clear, and there was a stubbornness between his eyebrows. Su Wu told him about his experience over the years, and let King Yu Jing look at the bare envoy. King Yu Jing respected his loyalty and felt compassion. So he put up a felt tent and stationed on the North Sea, leading the crowd to shoot and hunt every day. Su Wu got together for a long time and became familiar with each other, and in his spare time, he corrected their bows and crossbows and repaired all kinds of hunting equipment. King Yu Jing saw that he was very talented and more and more affectionate, so he provided him with food and clothing, and Su Wu took off his shabby clothes and changed them into new clothes, and abandoned the wild mouse grass to eat meat and buttermilk.

Time passed quickly, and more than three years passed, King Yu Jing suddenly fell ill and knew that he couldn't afford it, he was afraid that he would have no one to supply Su Wu after his death, so he allocated a lot of cattle and sheep utensils to Su Wu. King Yu Jing died soon after, and his subordinates did move elsewhere, and Su Wu was still alone, and the Ding Ling people near Beihai heard that Su Wu had a lot of livestock, so they led the crowd to steal them. Su Wu's life was poor again.

After Emperor Wu heard the news of Su Wu, he ordered Li Guangli to lead 30,000 troops to attack the Xiongnu. He also summoned Li Ling, the commander of the cavalry, to march with the army. Li Lingzi Shaoqing, is the grandson of Li Guang, his father Li Danghu died early, and his stomach was born. Less for the service in the construction of the chapter supervisor, good at riding and shooting, lover corporal, everyone is called. Emperor Wu thought that there was Li Guang's style, and he led 800 horsemen into the Xiongnu for more than 2,000 miles. This time, Emperor Wu summoned Li Ling to Wutai and ordered him to escort Li Guangli to carry a baggage. Li Ling kowtowed and asked: "The troops led by the ministers are all Jing Chu warriors, their strength can stifle the tiger, and the shot will hit. Emperor Wu said: "You don't want to be a subordinate, but I have sent a lot of troops, and there is no horse team with you." Li Ling said: "There is no need for a horse team, the minister is willing to attack the crowd with a small number, and he led 5,000 infantry to enter the court of Shan Yu." Emperor Wu saw that he was brave and courageous, so he sent him to escort the baggage to accompany Li Guangli.

Li Guangli led his troops out of Jiuquan, attacked the right Xianwang Yu Tianshan, beheaded more than 10,000 ranks, and returned with victory. The Right Xian King was unwilling to fail, and went to recruit a brigade to chase Guangli. Guangli was chased by Hu Qi halfway and surrounded on all sides. Li Guangli could not be drawn from the left to the right. At the same time, the food in the army was exhausted, the Huns attacked sharply from all sides, and the soldiers came from afar to be hungry and unable to resist the enemy, and six or seven out of ten were killed and wounded. At the critical moment, the fake Sima Zhao Chongguo led more than 100 strong men, and he broke through first, but when he saw that Hu Cai was densely covered like a bee tun ant gathering, Chongguo shouted into battle, and rammed into the spear and halberd forest, like a land where no one was in the world. Hu Bing died in the way, so he had to retreat, and he rushed out of the circle by killing the country. Guangli took advantage of the situation and led the soldiers to kill. In this vicious battle, Chongguo suffered more than 20 wounds and was fortunate not to die. Guangli returned to the capital to report, there was an edict to summon the country, Emperor Wu inspected the scars and bloodstains were not dry, and couldn't help but sigh for a long time, and immediately worshiped Zhonglang.

However, it was said that Li Ling led 5,000 people to go out of the obstacle until Dongjun Ji Mountain, and did not meet Hu soldiers all the way, and was waiting for the class teacher, and suddenly reported that about 30,000 people in the brigade had arrived. Li Ling set up a camp between the two mountains and surrounded it with large carts to prevent the enemy from clashing. He led his soldiers out of the camp and lined up in formation. Seeing that there were few Han soldiers, Shan Yu commanded Hu to attack the Han camp. Li Ling held on to the ground, and when the enemy soldiers approached, only a drum was heard, thousands of crossbows in the Han army were fired in unison, arrows were like flying locusts, the front team of Hu soldiers fell in response, and the back could not stand still, and they retreated up the mountain together, Li Ling led the crowd to cover up and kill for a while, and the Hu soldiers died thousands.

And Marquis Shan Yu saw that the battle could not be fought by Li Ling, so he hurriedly sent people to ask the king of the left and right to send troops to help in the war. The left and right Xian kings immediately sent troops to arrive, with a total of more than 80,000 horsemen.

Li Ling saw that Hu Qiman's strength was difficult to hold, so he fought and walked south. Shan Yu led the crowd to chase after him, and the Han soldiers marched for several days to a valley, and the Hu soldiers arrived, and the Han soldiers bravely resisted the enemy and suffered casualties. Li Ling ordered the soldiers to be carried by chariots with three wounded, the two wounded to push the carts, and the one wounded to fight with their troops, fighting bitterly with each other. After resting until night, Li Ling returned to the camp and said to his subordinates: "Why can't I beat the drums? Could it be that there are women hidden in the army? So he searched for it himself, and found many women in the cart. Li Ling inquired about the reason, but the wife and daughter of the Kwantung thieves were sent to the border, and the border army occupied them as wives, and they went with them on this expedition. Now he was found by Li Ling, and he was beheaded one by one with a sword. The soldiers were shocked when they saw it, but because they had violated the military order by taking women privately, it was cheap for them not to be punished, and whoever dared to stop them had to secretly regret and bury their bodies.

The next day, they fought with the Xiongnu again, and the Han soldiers were all desperate and courageous, and they beheaded more than 3,000 enemies. The defeat of the Xiongnu was rewarded by Shan Yu, and Shan Yu was unwilling to give up because of his many soldiers, and still urged the troops to catch up.

Li Ling defeated the chasing cavalry, led the troops to the southeast, and after four or five days came to a large lake, which was full of reeds. It was the middle of winter, and the north wind was blowing, and Shan Yu ordered his subordinates to set fire to the Han soldiers. Li Ling taught the soldiers to set fire to it first, so as not to prolong the burning. All the way through the south of the Great Lake to the bottom of the mountain. Shan Yu led troops to occupy the mountain and attack the Han soldiers. Li Ling saw Shan Yuqin supervising the battle on the mountain, and ordered Zhang Qi to shoot at Shan Yu with crossbows. Shan Yu timidly retreated down the mountain, convened the ministers and discussed: "This is the elite soldiers of the Han Dynasty who are tireless in battle, leading me south day and night, could it be that there is another ambush?" So it was decided to discuss withdrawing from the army.

Suddenly, it was reported that someone from the Han army had come to surrender. It turned out that the military marquis dared to be scolded by the captain, and went to surrender to the Xiongnu, reporting that the Han soldiers had no backup, and the arrows were about to be exhausted, only 800 people under the command of General Li and the captain Han Yannian. Han Yannian is a native of Yingchuan, that is, the son of Han Qianqiu. This time, he went out with Li Ling and is now a captain.

Shan Yu was overjoyed when he heard this, so he raised his troops and then attacked quickly. He also sent elite soldiers to make a detour to cut off their way before the Han soldiers, and shouted loudly: "Li Ling, Han Yannian descended quickly!" "The Han soldiers were trapped in the valley, and the Hu soldiers stood on the mountain, shooting arrows like rain on all sides. The Han soldiers shot all 500,000 arrows. There are still more than 3,000 soldiers in the inspectors, but how can they resist the enemy with empty bows left in their hands? Simply cut the wheels and cut off the axles to use them as weapons. Hu rode up the mountain to throw stones, and blocked the valley mouth in front, and most of the Han soldiers were killed.

At this time, it was getting late, and the two armies had a truce and had dinner each. Li Ling went out of the camp to look at the Hu soldiers, only to see the mountains and fields all over the camp. Li Ling was shocked when he saw it, and he expected that it would be difficult to escape, so he returned to the camp after thinking for a long time. Left and right did not dare to ask. But I heard Li Ling sigh and say: "The army is defeated and died." So he ordered the banner to be cut down and the treasure it carried, and to dig a large pit in the ground and bury it. Li Ling sighed to the generals: "Each person can get out with dozens of arrows, how can he fight without weapons now, and he will be tied." It's better to find a way to survive and flee in all directions, and if you are lucky, you can return to the Son of Heaven. After saying that, he ordered the soldiers to carry two liters of dry food and a piece of ice each, and each of them escaped. In the middle of the night, Li Ling ordered the drums to be beaten, but the drums suddenly stopped sounding. Li Ling and Han Yannian took the lead in killing a bloody road, and the soldiers followed out of the valley. Hu cavalry chased thousands of them, surrounded Li Ling and Han Yannian, and his subordinates were already scattered. Han Yannian died in a bloody battle, Li Ling recalled that there were only more than ten of his subordinates, and couldn't help crying to the south and said: "I have no face to see Your Majesty!" After that, he dismounted and surrendered to the Huns. Wrong, wrong! How to deal with Han Yannian?

More than 400 of the soldiers escaped, and the border officials were informed of the defeat. The border officials flew to report to Emperor Wu. Emperor Wu thought that Li Ling had died in battle, but after a while, he learned that Li Ling had surrendered. Emperor Wu was furious and summoned Chen Bule to question. Chen Bule was afraid of committing suicide, so Emperor Wu imprisoned Li Ling's mother and wife to protect the palace.

All the civil and military officials scolded Li Ling, and Emperor Wu of the Han Dynasty asked Taishi Ling Sima Qian how to deal with Li Ling. Sima Qian said:

"Li Lingti's infantry is less than 5,000, when the Huns are hundreds of millions of people, they are fighting for thousands of miles and arrows, and the soldiers are still vying to kill the enemy first. Although he is now trapped in Huzhong, his military exploits are also enough to be commended in the world. Therefore, the immortal may be waiting for the opportunity to make meritorious contributions. Emperor Wu thought to himself, I ordered Li Guangli to lead the army to go out and let Li Ling come to his aid, Li Ling preferred to do his own work, so that the army was defeated and surrendered. So he changed color and ordered Sima Qian to be handed over to Tingwei to deal with the crime. Tingwei was ordered to agree on Sima Qian's charges, saying that he should be sentenced to palace punishment. Sima Qian was actually tortured by Li Ling, which was really wronged.

After a long time, Emperor Wu repented that Li Ling was caused by no rescue, and said: "When Li Ling came out of the fortress, he originally ordered the strong crossbow commander to respond, but it was only because of the influence of this treacherous veteran that the edict was changed, so that Li Ling's entire army was annihilated. So he sent a messenger to comfort and reward the remnants of Li Ling. A year after Li Ling was in the Xiongnu, Emperor Wu sent Gongsun Ao, the general of Yinqi, to lead troops deep into the territory of the Xiongnu to pick up Li Ling.

Gongsun Ao returned in vain, but he said that he was captured by Hu Lu, and confessed that Li Ling saw that he favored the Huns and taught him to prepare troops to resist the Han, so the ministers did not dare to go deeper, so they had to return the army. Emperor Wu recalled Li Ling, regretted that he should not be sent out of the plug, listened to Gongsun Ao's words and believed it, but he was furious, so he ordered Li Ling's old mother and wife to be beheaded. Although Li Ling was guilty, Ling's mother and wife really should not be executed.

Another year passed, and Marquis Shan died of illness, Zihu Lugu succeeded and sent an envoy to the Han court to report the funeral. Emperor Wu sent people to hang, and Li Ling heard that his family had been killed, so he had to question the Han envoy. The Han envoy was about to recount what Gongsun Ao said, and Li Ling said: "This is what Li Xu did, what does it have to do with me." "Words of hatred.

The envoy returned Li Ling's words to Emperor Wu, and Emperor Wu realized his mistake, but he had no regrets. Li Xu was also a Han Chinese, and his official was the captain of the Saiwai Prefecture, defending the border city. The Huns came to attack, Li Xu opened the city and surrendered, only to treat the courtesy, often sitting on the top of Li Ling. Li Ling heard the words of the Han envoy and hated Li Xu's teaching of Hu Beibing to affect his old mother and wife, so he took advantage of Li Xu's unpreparedness to stab him to death. Shan Yu's mother, Da Yan, was furious when she heard about it and wanted to kill Li Ling. Shan Yu's beloved Li Ling was brave and good at fighting, hiding him in the north, and only returned after the death of the Da Yan clan. Shan Yu married his daughter to Li Ling, made her the king of the right school, and since then he has been with Wei Lu for a long time. Wei Lu is inside, and Li Ling is outside, all of them are like the heroes of the Huns. Later generations have a poem that sighs:

Alone in the battle of Fen Yuwei,

The poor were besieged;

It's a pity that he doesn't die in danger,

How can you excuse yourself for treason?
