It was guessed by Li Zuoche and suddenly rushed to the vicinity of Bantianling in the middle of the night under the banner of the Han army, which was indeed a fake arranged by Maodun, the purpose of which was to lure the Han army down the mountain to break through and create an opportunity for the Hun army to annihilate the Han army's Li Zuoche's department, and second, it was indeed to test the reaction of the Han army, so as to prove whether the Han army was deliberately surrounded by the Hun army.

In order to play realistically, the Xiongnu army pretending to be the Han army not only all marked with the banner of the Han army, but also the nearly 2,000 leading party from the Yan belt to the grassland of Zang Di also went into battle, all wearing the Han army uniforms taken from the dead bodies, and Zang Di personally led the rush to the front, so as not to be prematurely discovered by the Han army.

Mao Dun's plan also went very smoothly, after the fake Han army led by Zang Di rushed to the vicinity of Bantian Ridge, it was shouting and playing, which immediately attracted the attention of the Han army on the mountain, and the Bantian Ridge quickly burst into flames, and the crowd surged, obviously in an emergency assembly to prepare for action, Mao Dun and Zang Tu also secretly rejoiced when they saw it, and they all said: "Come down the mountain, come and die." ”

The Han army satisfied the wishes of Zang Tu and Mao Dun, after a while, the torches were chaotic, the Han cavalry took the lead, rushing down the mountain at the fastest speed, the infantry followed, and also walked down the mountain quickly with torches, Mao Dun and Zang Tu were overjoyed when they saw it, and cheered in unison in different positions: "The army of the tyrants (barbarians) has been fooled!" ”

The Han army did fall into a big daze, in order to get in touch with the receiving army as soon as possible, the Han cavalry did not stop, and without waiting for the infantry to go down the mountain, they rushed directly to the position of the fake Han army, and Zang Di pretended to be stopped by the Hun army, and ordered the fake Han army to stop advancing and shout in place. Shaking the torches, colliding with swords and guns, deliberately delaying the time to meet with the Han cavalry, so that the Han infantry had time to go down the mountain to die, and the Hun troops in ambush around were also ready to charge, just waiting for the signal to rush and kill in all directions, completely annihilating the Han infantry and cavalry that planned to go down the mountain.

The Han cavalry's breakthrough psychology was more anxious than Zang Tu imagined, and after rushing to the vicinity at the fastest speed, the Han cavalry desperately slashed and killed the Xiongnu army that was pretending to intercept with red eyes, and raced against time to approach the fake Han army, and before the Han infantry went down to the foot of the mountain, they had rushed to the front of the fake Han army, and couldn't wait to shout loudly to ask the origin of the fake Han army, "Where are you the army?" Who is leading the team? ”

Seeing this scene, Zang Di had no choice, in order not to be exposed prematurely, Zang Di could only step forward in person and shouted at the Han soldiers who rushed quickly: "We are from Mayi, General Nie sent us to meet you!" Quick, tell your infantry to keep up! ”

"Ahh Oops! How is he? ”

When he shouted here, Zang Di suddenly screamed bitterly in his heart, and subconsciously lowered his head, because Zang Di suddenly saw that the one who led the Han cavalry to the front was actually Xiang Yu's cousin who had dealt with him a lot before-Xiang Guan! However, what made Zang Tu even more distressed was still behind, Xiang Guan actually recognized him at a glance, and immediately roared angrily, "Zang Tu is a traitor!" It's you?! ”

"Fooled! It's our army that the Huns are impersonating and impersonating! Come on! ”

Xiang Guan shouted this justifiably and quickly, and then pulled out the horse's head even more quickly, shouting the order to retreat, while charging back to the mountain with the Han cavalry, Zang Tu saw helplessness, so he could only quickly shout: "It's discovered, hurry up!" Kill all these thugs! Kill——! ”

The shouting of killing also really sounded, and the fake Han army led by Zang Di shouted up, chasing the retreating Han cavalry at the fastest speed. At the same time, judging from the torch situation, after the Han cavalry had begun to retreat, Mao Dun did not understand why the fake Han army was recognized so quickly, but he also decisively ordered the drum to send a signal, so that the Hun ambush soldiers who were ambushed around immediately killed, and killed the Han cavalry who were planning to go down the mountain from all directions, and of course, there were ambushes to kill the Han army infantry who were still on the way down the mountain.

What followed was naturally a brutal and fierce bloody battle, in the end, less than half of the 3,000 Han cavalry who went down the mountain were able to escape back to the mountain, Xiang Guan himself was also wounded in the fierce battle, and he was lucky to escape back to the mountain to meet Li Zuoche by relying on his own soldiers' life.

Then, when it was all dark, Mao Dun naturally had to call Zang Tu in front of him, and asked him face to face why he was prematurely recognized by the Han cavalry, and Zang Di, who was placed by Mao Dun with eyeliner next to him, did not dare to hide it, so he could only honestly admit it: "The Great Khan forgives the sin, it is the bad luck of the subordinates, when the subordinates personally came forward to deceive the tyrant army, they happened to meet the tyrant general Xiang Guan, who used to meet with his subordinates often, so he recognized us as fakes at a glance." ”

After that, Zang Di told the truth about Xiang Guan's identity and his many dealings with Xiang Guan, and Mao Dun naturally shouted bad luck when he heard it, and said regretfully: "It's a pity, if you didn't happen to meet someone you know, we could have completely annihilated the barbarian army last night." ”

Zang Di had no choice but to ask for guilt again, but fortunately, Mao Dun was also quite generous, waved his hand and said: "Forget it, this matter is a matter of luck, and it has nothing to do with you." Fortunately, we didn't work in vain, at least we killed a lot of barbarian soldiers, which also proved that Li Zuoche's barbarians were indeed in a hurry to break through and flee for their lives, so that we could continue to surround them with confidence. ”

After finishing speaking, Mao Dun hurriedly ordered Zang Di: "Don't be idle, go and interrogate those captured barbarian soldiers, and ask what the situation of the barbarian army on the mountain is, and how much military ration is left?" ”

The results of the interrogation of the prisoners of course made Mao Dun overjoyed again, and some soft-boned Han cavalry truthfully confessed, admitting that the Han soldiers on the mountain were frozen to death and frostbitten very seriously, and at the same time, in order to save rations, Li Zuoche had already ordered all Han soldiers to eat only half a day's dry food every day, including the wounded soldiers. After hearing this, Mao Dun was naturally extremely happy, and decisively decided: "Continue to besiege the mountain, no matter what, we must completely annihilate this barbarian army!" ”

In this way, because of Li Zuoche's deliberate scheme, Mao Dun, who had already been a little shaken, once again strengthened his determination to trap the Han army, and the number of more than 300,000 Xiongnu troops set up camp on all sides, surrounding the Bantianling Heights, and the 145,000 Huns, old and weak women and children set up camp in the east far away, slaughtering cattle and sheep every day, milking cows and cheeses, and feeding the soldiers of the Xiongnu army. At the same time, Mao Dun also adopted Zang Di's suggestion, built a fortress wall around Bantianling, completely trapped the Han army, and sent people to the mountain from time to time to shout and surrender, persuading the Han soldiers on the mountain to go down the mountain and surrender. Not to mention, because I didn't know that the dawn was just around the corner, there were really some Han soldiers who were greedy for life and afraid of death quietly went down the mountain and surrendered, which not only let the Hun army know more about the situation of the Han army, but also seriously affected the morale of the Han army. After this situation was reported to Li Zuoche and Xiang Guan, Xiang Guan suggested that Li Zuoche disclose the truth to stabilize the army's heart, but Li Zuoche shook his head resolutely and said: "We can't let our soldiers know the truth, otherwise, even if a soft bone hears the news, it may lead to the loss of our previous achievements!" ”

The tricks of the Xiongnu army were not only these, so three days later, Mao Dun adopted the suggestion of Zhang Sheng, the pioneer of the leading party, and ordered the Xiongnu soldiers to cut down countless trees from the surrounding area, piled them up at the foot of Bantianling Mountain and set fire to the mountain, the fire was blazing, the smoke was billowing, and many Han soldiers in the high place were smoked to tears, coughing constantly, Li Zuoche was helpless about this, and could only repeatedly strict military orders, forcing the Han soldiers to continue to work hard and endure.

It was also on this night that the situation changed a little, a messenger of the Han army who came from Mayi took advantage of the cover of night to try to sneak up the mountain from the weak point of the encirclement of the Hun army, but unfortunately his luck was not good, he was found by the Hun cavalry only halfway through, and the letter he was carrying was searched out by the Hun cavalry.

Anxious to know the movements of the Han army, Mao Dun of course couldn't wait to open the letter to check the contents, but what made Mao Dun dumbfounded was that in addition to the signature and seal of Nie Zheng, the general of the Han army's Ma Yi, there was only one Chinese character written on the letter that he didn't know what it was. Mao Dun was strange, and hurriedly asked Zang Di and Zhang Sheng who were present about the reason, but Zang Di and Zhang Sheng just glanced at each other, and then immediately said: "It's a secret letter!" It's the secret letter of the tyrant army created by Xiang Kang, the dog emperor himself! ”

"What do you mean? Be clear. Mao Dun asked even more puzzled.

"Great Khan, this is the case." Zhang Sheng replied: "Your Majesty heard that in order to prevent the messenger from being intercepted during the war, the tyrannical emperor Xiang Kang personally created a secret letter, that is, he agreed with the important generals in advance on a poem, and every word on the poem represents a meaning, for example, asking for help or food, what does the specific word mean is only known to the person who writes and receives the letter, so that even if the messenger is intercepted, the enemy does not know what the secret word on the letter represents. ”

"And this method of secrecy? Can we learn? Mao Dun exclaimed, and asked with a glimmer of hope, "Then do you know what this word means?" ”

Zang Di and Zhang Sheng shook their heads and smiled bitterly, saying that they had only heard of this method, in fact, they had never used it, Mao Dun was disappointed when he heard it, and could only point to the Han army messenger who was escorted in front of him and ordered: "You interrogate him, ask what is the situation in Mayi City, and what is the reaction of the Central Plains barbarians, the more detailed the better." ”

The result of the interrogation made Mao Dun even more disappointed, although the Han army messenger opened his mouth, but only explained the general situation of the defenders of Mayi, and confessed that the defenders of Mayi did not dare to send troops to rescue Li Zuoche because of too few troops, and he did not know anything else. Mao Dun was helpless when he heard this, so he could only wave his hand to let the guard escort the messenger away, and then picked up the simple book and pondered with confidence, and said secretly: "Although this kind of secret character of the Central Plains barbarian is clever, it can definitely only convey some simple meanings, what will it mean?" Called the surrounded barbarians to break through? Or do you want to make an appointment to pick up? Or is it that reinforcements are coming? ”

Thinking of this possibility, Mao Dun, who had too many old and weak cattle and sheep in the army, suddenly felt a little drumming in his heart, and subconsciously gave birth to a feeling of unease, and couldn't help but say in his heart: "Am I wasting too much time?" If a large number of troops of the Central Plains barbarians really arrived, even if my army could retreat quickly, the cattle, sheep, and old and weak would not be able to escape? ”

It was also a coincidence that on this night, a few Han soldiers who were greedy for life and afraid of death quietly went down the mountain and surrendered, so that Mao Dun knew that the situation of the Han army on the mountain was more critical, and Mao Dun also quickly made up his mind and said secretly: "We can't delay any longer, although the barbarian army on the mountain is running out of food, but they can still kill horses and eat meat, and expect to starve them to death directly, I don't know what year and month it will take." Anyway, I have a lot of soldiers, as long as I can annihilate the barbarians on the mountain and capture their weapons and armor, even if three for one is worth it, it is better to attack the mountain directly! ”

After making up his mind, on the second day, Mao Dun decisively ordered the Hun army to go out and attack the top of the mountain directly on foot.

This battle was fought more tragically, in the wind and snow, the Huns in leather clothes were overwhelming, the crowds were charging continuously, and the Han soldiers with many wounded soldiers could only rely on the limited geographical advantages to stubbornly hold on, and the Hun soldiers who were more suitable for this weather fought desperately in the ice and snow, it was just noon, several key positions were already full of corpses, blood flowed, warm blood melted the ice and snow, blood and water flowed down the hillside, stained a large area of snow red, and formed blood ice.

The three infantry teams of the Han army were directly disabled, and their thousands of people will all be killed and sacrificed, and the feather arrows are densely packed on the mountainous ground, and the number is comparable to that of weeds. And during this period, Li Zuoche was even ready to kill himself.

The fierce battle lasted from early morning until it was dark, and the casualties were too heavy, although several Hun nobles ran to Maudun to cry and wail, begging Maudun to leave a little seed for their tribe, Maudun was still unmoved, but shouted with a blue face: "Order the whole army, light the torches, and attack the mountain for Ben Khan overnight!" Even if it takes three days and three nights, all the Central Plains barbarians on the mountain will be killed by Ben Khan! ”

The torches of the Hun army were quickly lit, and seeing this scene on the mountain, Li Zuoche laughed bitterly loudly and had to shout: "Order the whole army!" Let all our soldiers know that our reinforcements are coming! As long as we hold on until tomorrow, our reinforcements will surely arrive! ”

The order was conveyed, and the generals of the Han army also made similar roars, using the news casually fabricated by Li Zuoche to boost the morale of the army, but this situation was quickly heard by the leading party hidden in the Xiongnu army, and it was quickly reported to Mao Dun, who laughed and said: "Use false news to boost the morale of the army, the barbarians are almost unable to hold on, give Ben Khan an order to go down and step up the attack on the mountain!" Annihilated the Central Plains barbarians on the mountain, and everyone ....... ”

"Report ——!"

With a panicked and anxious shout, Mao Dun's order was interrupted, and when Mao Dun subconsciously turned his head to look, he saw that a Hun scout was stumbling from the south, and hurriedly asked, "What's wrong?" In such a hurry? ”

"Great Khan! Barbarian army! Barbarian army! The scout yelled twice in a row, and then shouted a complete sentence, "The barbarian army of the Central Plains is coming, and at noon they have crossed the Juzhu Mountain!" The number is so large that it can't be counted, the front team has already driven to the city of Mayi, and the back team has not crossed the Juzhu Mountain! ”

He stood up suddenly, his face was first whiter than the white hair of his beetle, and then it was quickly gloomy like water, and the iron was almost black!
