King Huyan was defeated by Geng Gong again and again, and he was very unwilling, but he was injured, so he had to retreat and recuperate for the time being. Fearing that the Hun soldiers who were wounded by the arrows would attack violently, Pu Nushan sent people to sneak into the wooden camp in the middle of the night on the pretext of treating the arrow wounds, set off a nameless fire, and burned all the Huns who were wounded by the arrows. In the Xiongnu army, there were many complaints, but Pu Nu didn't care, he only cared about having fun with Ruyan every day, ignoring the military, King Huyan was angry, and he hated Ruyan to the bone.

Since the defeat and retreat of the Huns, Geng Gong said to the generals: "Although the Huns are unwilling, the king of Huyan has been injured, and this retreat, at least half a year, dare not attack again." Jinmancheng is easy to attack and difficult to defend, and the next time the Huns come, we will not be able to resist! The top priority at the moment is to abandon Jinmancheng and choose another dangerous place to defend before confronting the Xiongnu. When the people of Jinman heard that the Han army had retreated, they all wept in front of the camp and were willing to go with the army. Geng Gong agreed, led the Han soldiers to abandon the city, took the people of Jinman, dragged their families and mouths, and moved together, and went north. Shi Xiu was puzzled and asked: "General Geng, the south is close to Yumen Pass, and the Xiongnu are coming to attack, which is more conducive to asking for help, why do you want to go far and near?" In case of difficulty, wouldn't it be difficult to speak alone? Li Dang laughed and said, "Shi Xiu, we are going to the Western Regions to kill all the Huns, why do we have to go south?" Where are the Huns in the south? You have to be afraid, before the Huns come, hurry back to Luoyang! ”

Geng Gong said: "We have gone through thousands of hardships and spilled countless blood to have today's good situation. If it goes south, won't it give up a large area of land in the Western Regions? Even if I'm in one breath, I don't want to do this! When I was with my younger brother Ban Chao in the Tianshan Mountains, I talked about the fact that there was a city in the Cheshi, called Shule City, which was very high, with high mountains on three sides, and no one could cross it, which was very dangerous, and the other side was also condescending, facing a narrow plain, just the opposite of Jinman, easy to defend and difficult to attack. Moreover, Shule City is the throat of the Xiongnu, if the Xiongnu want to go south, they must pass through Shule, Shule is not restrained, and the Xiongnu do not want to enter the southern part of the Western Regions in half a step! The people rejoiced.

Due to the presence of the people of Jinman, the marching speed was very slow, and it took more than ten days to reach Shule City. Everyone entered Shule City, and when they saw it, as Geng Gong said, it was a one-man pass, and ten thousand people were not open! Shule City is on the mountain, condescending, the other three sides of the mountain stand majestically, one after another, endlessly, there is not the slightest gap in the middle, the Shule City is surrounded by a group, the mountain is straight and steep, even if the gods, it is difficult to cross, it is a natural barrier! What's even more strange is that there is a mountain stream, which flows in from outside the city, and the spring water is clear and very pleasant. Fan Qiang sighed: "I saw that the road in the city, full of footprints, messy, the Huns must have retreated from now on, they are really incompetent, such a precipitous place, why don't you send people to defend it?" Now that he has it, he has an army of 100,000 men, and he can't think of going any further! "The Han army and the people of Jinman entered the city, after Geng Gong settled, arranged the city defense, and took Fan Qiang and others, patrolled along Shule, saw that the city wall was in disrepair, there were cracks everywhere, and it fell down at a touch, and the next day he brought people to the mountains to build a city, busy and busy, after several months, it was built, this Shule city became impregnable!

Geng Gong didn't dare to be too careful, sent troops to garrison, and did not dare to slack off. And where there are mountains on three sides, sentinels are also set up. The Huns really didn't dare to come again, autumn and winter came, the snow was flying, Shule City was covered in silver, that Li dared to stay in the city every day, very boring, this day ran to Geng Gong, said: "Big brother, stay in this palm-big place every day, it's really boring, now it's snowing so much, the Huns won't come, you see my Xuantie knife, it's about to rust, it's better to call Fan Qiang, let's go hunting, okay?" ”

I couldn't help Li Dare to beg again and again, Geng Gong stayed high to defend the city, shouted Fan Qiang, Wen Chi, Shi Xiu, Zhang Feng and others, stepped on the thick snow, and went out of the city gate. Since entering Shule City, the generals went out of the city for the first time, only to feel that the sky is wide and the earth is wide, refreshed, and so unhappy. One by one, the horses galloped, wielding knives and bows, and the vicinity of Shule City was uninhabited for a long time, and there were many animals. In a short time, the fruits were abundant, and the horses of the accompanying soldiers were loaded with hares, foxes, and other animals. Suddenly, there was a black spot in the distance, running lifelessly, Li dared to see it, was overjoyed, and said: "Big brother, I saw that the running animal was quite large, I am afraid that it is a leopard." ”

Geng Gong said: "Nonsense, how can a leopard run so slowly? ”

"It's not a leopard, it's a bear or something. Big brother always laughs at me for my good knife skills, but my archery skills are not good, today I caught this bear with an arrow, how about it? Without waiting for Geng Gong to agree, Li Dare snatched the bow and arrow in Wen Chi's hand, slapped his horse forward, and shouted loudly: "Where to run!" When he shot three arrows in a row, the arrows missed, either high or low, and everyone burst into laughter.

Li Dang thought to himself: "If I don't catch this bear today, I will become a bear, I will be laughed at by them every day, and I will be a man with my tail between my legs in the future, and I will never be able to raise my head again!" He clamped his legs, the horse was like a meteor, kicking the starting point of the flying snow, Li Dare sat on the horse, pulled the bow, aimed tightly, did not dare to relax for a moment, and said in his heart: "This arrow, I will definitely shoot it!" ”

Suddenly, Geng Gong shouted: "Brother Dare, don't let go of the arrow, that's not an animal, it's a human, it's a human!" Don't shoot arrows! Li Dare was willing to listen, and thought: "Even if it's a human, I'll shoot it first!" Drawing the bow and shooting an arrow, Li Dang was originally powerful, and this arrow, with the sound of wind and thunder, flew towards the black spot with a "whoosh".

That black dot is actually a person! He saw that this arrow rushed towards his heart, and he couldn't dodge, so he pulled out his knife, and made a move to "swallow turn back", and cut it hard, just cutting the arrow into two, and his body was vigorous, and he looked like a family. Geng Gong and the others were shocked, thinking: "Could it be that the Huns came to investigate?" You can't let him go! And they all slapped their horses forward and overtook the man. I saw that the man's hair was disheveled, his long beard was knotted, his clothes were in tatters, and he hung on his body one by one, but the sword in his hand was shining.

Geng Gong and the others surrounded him tightly, and Li Dang pointed at him with a knife and shouted, "Who are you?" Is it the meticulous work of the Huns? When the man heard this, he was stunned, and then he suddenly abandoned his sword, and fell on his face in the snow, and began to weep bitterly. Li Dang was puzzled: "What's wrong with this?" Looks like a man, why is he so cowardly, and when he sees that he is surrounded by us and has a dead end, he starts crying? ”

Geng Gong felt that this person was very familiar, and asked, "Don't cry, strong man, who are you?" Where do we seem to have met? The man raised his head and cried and said, "Big brother, don't you know me?" I'm Gao Feng! Everyone was shocked, turned over and dismounted, Geng Gong hurriedly stepped forward, helped Gao Feng up, brushed away his long and messy hair, and said in a trembling voice: "You, aren't you in, in Shule Country?" In my brother Banchaona, why did you get here? Gao Feng cried loudly: "Big brother, it's hard to say!" Geng Gong hugged Gao Feng tightly, he knew that this journey must be extremely difficult, and Gao Feng didn't know how much suffering he had endured! I didn't want to hunt anymore, so I pulled up Gao Feng, rode together, and led the crowd back to the city.
