Jingshui originates from the eastern foot of Liupan Mountain outside Saiwai, passes through Longbei, and enters Weishui from the eastern suburbs of Xianyang. Jingshui because of the passage of the Loess Plateau with serious soil erosion in Longbei, so once the rainstorm occurs, the river water will be turbid, which is the saying of "clear and turbid" and "clear distinction between Jing and Wei". During the period of the First Emperor, in order to launch a war against the Xiongnu, hundreds of thousands of displaced people and prisoners were sent to Saibei to reclaim, so a large number of trees in Longbei were cut down, which aggravated the trend of water and soil flow.

Jingshui River is narrow, there are many heavy rains in summer and autumn, so it is known for the fierce flood, the sediment is many, the flood is impermanent throughout the year, every time the big flood will submerge most of the rich Guanzhong downstream, the Qin people complain about it again and again, suffer from it.

This situation was not changed until the first year of the first emperor, a waterworker named Zheng Guo came to the Qin State at that time, and put forward a bold idea to the newly enthroned Qin King Yingzheng, he proposed to use channels to run through Jingshui and Luoshui, which was enough to irrigate tens of thousands of hectares of fertile land along the way, which could not only greatly enhance the national strength of Qin, but also channel the river water of Jingshui into Luoshui during the flood season.

The young and promising King Yingzheng of Qin was very interested in this proposal, and after discussing with Lü Buwei of Xiangguo, he poured the strength of the whole Qin State into digging this channel. However, when the channel was halfway through, Zheng Guo's conspiracy was revealed, and it turned out that the channel he built was the idea of "tired Qin" in order to maintain the crumbling national situation of Korea, hoping to exhaust Qin's national strength and be unable to go east.

Qin Wangzheng was immediately furious and wanted to kill Zheng Guo. Zheng Guo said: "The first minister is the middle, and then the benefits of Qin are also good." The minister is the life of Han Yan for several years, and the merit of Qin Jian for all generations. Qin Wangzheng was a far-sighted statesman, and he thought that Zheng Guo was very reasonable, so he pardoned him for his guilt and continued to entrust him with the important task of building the Zheng Guo Canal. As Zheng Guo said, after the canal was built, 40,000 hectares of fertile land along the way were watered, and at the same time, the flood disaster that had plagued the Qin State for hundreds of years was solved, laying a solid foundation for the Qin State to dominate the world.

Another lesser-known function of the Zhengguo Canal is its ability to store water, closing the sluice gates and hoarding water in times of drought. It's just that the climate in Guanzhong is humid, and there is very little drought, and over time, this function of Zheng Guoqu has also been forgotten by people.

A rare spring rain brought Han Xin a chance to win. Jingshui is formed by the merging of several tributaries, and the water level rises every time it rains, and only the embankments along the banks can withstand the floods. If it is normal times, it does not matter, there is the Zhengguo Canal channeling, flowing through the Luoshui into the big river, this kind of flood is not a matter of concern at all, but if it is artificially stored flood, it is a different matter.

Although Maudun is a hero, he has never heard of floods on the grassland, let alone thought that floods can be used by people. Although Yan Fu is scheming and proficient in various military arts, he only knows that there will be floods in the summer and autumn seasons, and although such continuous heavy rains in spring are rare, they will not cause floods.

What they didn't expect was that Han Xin would be able to ruthlessly use more than 50,000 troops as outcasts, using this as bait to attract the hungry wolf of the Huns. Even if they were lucky enough to survive the onslaught of the Huns, they would have been drowned by the flood.

Han Xin knew that this plan was too vicious, and it would not only push the Huns into a desperate situation, but also force this partial division to death. But he had no choice, the Great Wall had been broken, and there was no danger north of Guanzhong, so he could only rely on the fortified cities in Guanzhong to fight a protracted war.

The Huns did two things in their lives, nomadism and plundering, and they did not need to cultivate or logistics. The Qin people, who founded the country on agriculture, were different, and if they fell into a protracted war, the Qin state, which had just recovered a little vitality, would inevitably fall again, and there would be no eastward competition for the world.

So Han Xin had no choice, and Qin State had no choice.

The use of extraordinary methods in extraordinary times, the smallest losses, in exchange for the greatest results, this is not the essence of the art of war most admired.

But Han Xin also knew that once this matter came out, there would be an uproar in the Qin State. The army of the Qin State is not afraid of life and death, and is not afraid of fighting to the death, but it has never been killed by its own people, and it is a whole army. Therefore, Han Xin did not tell anyone his intentions, only Zhang Liang guessed it with his ingenuity.

Han Xin did not completely abandon Zhao Wuji's partial division, but carefully chose Yang Zhou, which was slightly higher in terrain, as a stronghold. and repeatedly instructed Zhao Wuji to act at the opportunity, and promptly brought the remnants of the Qin army to a high place to avoid the water. And Zhao Wuji also willingly wanted to rely on this miraculous feat to wash away the previous shame in one fell swoop, Han Xin chose him, so he nodded and agreed without hesitation.

Under the big water, the ocean was suddenly overflowing, and the flood poured down from the Zhengguo Canal, and suddenly overflowed the entire Beidi County, seizing the way of Luoshui to the northeast and injecting it into the big river, and Yangzhou was at the last stop in the west of Luoshui.

The wrath of Tianwei is not something that human power can resist. The Huns frantically whipped their horses, desperately rushing towards the north, but could not change their fate at all, the waves that chased up soon swept all the grassland tribes, and the invincible iron horsemen who had galloped the grassland were easily defeated by the flood.

This flood came and went quickly, and Luoshui was injected along the low-lying areas north of Yangzhou City. After all, it was a man-made flood, and it was difficult to have follow-up power, and after more than half an hour, the water receded outside Yangzhou City, leaving only a mess.

Most of the impermeable Huns did not withstand the first wave of the flood peak, and were soon swept up by the waves and drowned. The rest of the people were lucky enough to make it to the high ground, or slightly waterlogged, and survived the flood, and Maudon was one of them.

At this time, he was soaking wet, looking extremely embarrassed, and there was still a trace of the demeanor of the male lord of the grassland. His heart was dripping blood, and the hatred and remorse in his stomach almost drove him crazy, and he didn't understand until the moment before the flood that all this was Han Xin's trap, that is, he wanted all the Huns to die without a place to bury.

These are all the results of his painstaking management for more than ten years, but Han Xin used such a way to make all his efforts go to waste.

Although Mao Dun was already heartbroken at this time, he still forced himself to calm down, and he kept telling himself that he hadn't lost yet, and he still had a chance to turn the tables. The 50,000 elites of Ji Congee, as well as the besieging army of Hu Yanyu of Fu Shi, the Huns still have a chance, there must still be it!

The people around them all looked at their Shan Yu, one by one panicked, six gods without masters, hoping that their great Shan Yu could bring them out of a desperate situation and use his wisdom to save the Huns from the doom of defeat. Mao Dun forcibly calmed down, raised his head, and although his voice was hoarse, it revealed his previous calmness and wisdom.

"Put up my royal flag, go all the way north, don't stop, all the way north, all the way north."

Mao Dun guessed correctly, although the flood was deadly, it was not enough to wipe out the entire Hun army, and many people were just washed away, and did not lose their lives. Mao Dun erected the king flag that symbolized Shan Yu, along the way there were constantly three or three Huns returning to the team, the team rolled more and more, and even gathered more than 60,000 people, which also made Mao Dun's ambition to be extinguished again, as long as it was ten days later, he would definitely be able to gather more troops, plus the army of Hu Yan, if Ji Congee succeeded in Guanzhong, the Huns might be able to turn defeat into victory.

It's a pity that Han Xin didn't give him this opportunity, and the Qin army's iron cavalry almost followed the aftermath of the flood, and the Qin army began a major counterattack. For this counteroffensive, Han Xin gathered all the cavalry, and divided 70,000 iron cavalry into four teams, which were divided into four teams by him, Meng Shi, Yingbu, and Wang Qi, and launched a huge counterattack to the north. Zhang Liang led the rest of the footmen and followed to expand the results.

The flood not only caused heavy casualties to the Huns, but also destroyed all their pride and self-confidence. When the sword of the Qin cavalry appeared on the horizon, the entire Xiongnu army collapsed instantly, and the remnants of the soldiers who had been gathered with great difficulty scattered in a hurry, and everyone fled desperately to the north, thinking only of how to escape for their lives, and escape back to the grassland to survive.

Mao Dun closed his eyes in pain, and at this moment he really understood what it was to be defeated, and he did not bother to gather his troops to resist the Qin army in vain. Because the Hun army has been scattered and has no fighting spirit, staying is nothing more than sending them to death in vain, it is better to let the sons and daughters escape by themselves, and they can also retain a little vitality for the grassland.

He was completely desperate at the moment, he expected that the army of Hu Yanyu would become the next trophy of the Qin army, and even if the sneak attack on the army was successful, what could they do if they lost their foundation? It was nothing more than killing as much as he wanted, and then he was killed by all the Qin troops who returned to the division.

The Huns are finished, completely finished, and the army he brought to Qin this time is almost all the young and strong of the Huns. It will take at least ten years to breed a new generation of warriors, and his enemies will never give him that much time.

The first to catch up with the Huns was the Yingbu Division, who was suffocated in the camp at this time, like a wild horse that had escaped from the brisle, brandishing a big knife and rushing at the forefront of the ranks. However, the Huns did not cooperate with him, and most of them scattered as soon as they saw the banner of the Qin army, which made Yingbu almost like no one all the way, just mechanically harvesting panicked heads.

This also made him extremely unhappy, and the resentment in his heart became more and more suffocated, until he caught up with a group of Hun cavalry fleeing in the northwest direction.

This team of cavalry is different from other Huns, in the grassland, armor is a very luxurious thing, most of the Hun soldiers are simply hanging a quick iron sheet at the vital point on the hastily things, and this pair of cavalry is actually covered in golden armor, and the weapons in their hands are also extremely sharp, not inferior to the sword of the Qin army.

The number of this pair of Hun cavalry was not large, but more than 3,000 people. According to the idea of the Qin army, the rout of the pursuit of three thousand, one thousand people was more than enough, so the first to discover the song of a thousand Qin army did not wait to return to Yingbu, so they happily rushed directly to kill.

The result was beyond all expectations, the Huns burst out with terrifying combat effectiveness, and the Qin army of 1,000 people was almost wiped out, and only a few dozen people escaped to report the news.

Yingbu in the rear was shocked and angry when he got the news, and immediately ordered the five thousand headquarters to pursue the Huns in the starry night. Finally intercepted them under a hill.

In a bloody battle of hand-to-hand combat, relying on the bravery of Yingbu and the superiority of the Qin army, the Huns were wiped out without any suspense, but it also brought nearly 4,000 heavy casualties to the Qin army, and the rest were less than 23 out of ten. Only then did Yingbu know that these 3,000 people were the famous Shan Yu's own soldiers on the grassland, the Golden Horde Horseman, and the nature they guarded was the supreme existence on the grassland - the Huns' plough was lonely and alone.

The news of Maudun's capture alive was quickly reported to Han Xin by Yingbu through a fast horse, and Han Xin, who was besieging Huyanyu, immediately left his army behind and hurried to Yingbu's camp.

To know what it meant to the Qin State to capture Mao Dun, no one would know better than Han Xin, who was at the helm of the Qin State. This is definitely a big victory, an unprecedented big victory, a big victory that can make the entire Qin State exciting! He has done what the First Emperor has never done, so what is impossible?

Han Xin worked fast along the way, although he hadn't closed his eyes for two days and two nights, he was extremely excited and didn't feel any tiredness at all. But after seeing Yingbu in the Yingbu camp, his joy slowly faded.

"He's right there." Yingbu pointed to a camp tent in the distance, and subconsciously lowered his voice.

This camp tent looks extremely ordinary, just like the tents built by ordinary Huns, but it is a little abrupt in the camp of the Qin army. Yingbu did not add harshness to Maudun, but on the contrary, he was full of courtesy.

Han Xin slowly walked into the camp, his heart was full of emotion, he had thought about the scene when he met Mao Dun countless times, he had thought about Mao Dun gritting his teeth at him, and he had thought that he was very proud, but he never thought that it would be so natural, plain as the surface of the water.

Mao Dun just raised his head and said lightly, "You're here." The tone was ordinary, as if he was waiting for an old friend to visit.

Han Xin bowed slightly, pressed his chest with his right hand, and performed a ritual on the grassland, "Han Xin has seen Da Shan Yu." ”

"Sit down." Mao Dun casually pointed to the seats on both sides, looked at Han Xin with a calm face and sat down, and said; "Finally waited until you came before my patience ran out."

Han Xin smiled, but was speechless, he suddenly noticed that Mao Dun looked very different. Half a year ago in Hedong, at that time, he was full of energy and radiant, and his words and deeds revealed incomparable confidence and domineering. But now, he looks much older, and even his always straight body can't help but be a little rickety, and although there is a faint smile between his eyebrows, he can't hide his deep loneliness.

Maudon lowered his glass, "I want to know how you beat me, please let me know if it's convenient." ”

Han Xin did not hesitate, but said it in detail, his tone was flat, as if he was only talking about something that had nothing to do with him.

After listening to what Han Xin said, Mao Dun nodded, and a trace of strangeness flashed in his eyes, "I see, there is such an ingenious water conservancy in the world." I have admired the culture of the Central Plains all my life, and I have always thought that I am different from those rude grassland men, but I didn't expect that I am still arrogant out of thin air, blind, and I don't know the spring and autumn. It seems that what I have learned in my life is only the surface of yours, and I should be convinced. ”

"Then I can rest assured, and I will have no complaints."

Listening to Mao Dun's tone, Han Xin faintly felt a little bad, and said with some unbearability in his heart; "Shan Yu, have you thought about the future?"

Mao Dun smiled slightly when he heard this, and looked at Han Xindao with some playfulness; "I want to ask you, General, what do you plan to do with me."

"I'm going to let you go back to the grassland, of course, just you." Han Xin said in a deep voice.

Mao Dun was stunned, "What do you mean?" ”

"Kunmo ran away, and Lou Annoying withdrew to the grassland intact."

Mao Dun thought about it and understood the meaning, Han Xin obviously didn't want Lou's annoying family to become bigger. The grassland is too big for the Qin State to swallow, and the most beneficial thing for the Qin State at present is nothing more than the fragmentation of the grassland, and there will be no threat to the Qin State from now on.

After this battle, the Huns have completely lost their vitality, and Lou Fu is still full of spare strength, will definitely expand frantically to fill the gap left by the shrinking power of the Huns, relying on his means, it is not impossible to replace the Xiongnu to unify the grassland, and then Qin will have a strong opponent.

And even if Maudun returns to the grassland, he will be like a tiger who has lost his minions after losing his army, and he will not be able to return to the sky. can only rely on the titles of Yu Wei and Shan Yu to barely support the Huns, and contain the annoying expansion of the building. Obviously, Han Xin's abacus is very shrewd.

He expected that Mao Dun would agree, because he was an ambitious person, and ambitious people would always be unwilling to fail, and would always fantasize about making a comeback.

But he miscalculated, Mao Dun just raised his eyebrows, and said in a flat tone; "I refuse."

Han Xin was stunned for a moment, and then asked; "Why? When you return to the grassland, you are still the high-ranking Shan Yu, it is better than being a prisoner in the Qin State, and besides, if you wait patiently for the last ten or twenty years, the Xiongnu may not be able to become strong again. ”

Mao Dun's smile gradually faded, "You're right, if you endure humiliation, I may not have no chance." ”

"But I still have to refuse, refuse your mercy, refuse your charity."

Mao Dun slowly stood up, tried to straighten up, raised his head and said loudly; "Do you know who I am? I am the goshawk on the steppe, the supreme plough of the Huns, the son of immortality! His proud pride would never allow him to accept handouts from his enemies, and the goshawk would never bow his noble head for the sake of poor food that could only fill his stomach. ”

"There is only Mao Dun who died in battle, and there is no Shan Yu who kneels to survive!"

At this time, Mao Dun suddenly returned to his original appearance, his eyes were blazing, his voice was like a bell, and he leaned over and looked at Han Xin with a proud face, as if he was the victor.

This is the goshawk of the steppe, the son of heaven!

Han Xin was silent for a long time, then bent down deeply and saluted; "I shouldn't have insulted you, I apologize to you."

Mao Dun looked up to the sky and laughed, his smile was full of pathos, and he seemed to be a little relieved. He pulled out his saber sharply, pointed at Han Xin and said loudly; "Now, my honorable general, please draw your sword and give me one last ride with the honor that a steppe warrior deserves."

……

Inspector Yingbu outside the tent had his head long, waiting anxiously for Han Xin to come out. He heard a loud commotion in the tent, then a fight of weapons, and then silence. If it weren't for his confidence in Han Xin's skills, he couldn't help but want to rush in to find out.

When he saw Han Xin walking out of the camp, Yingbu anxiously stepped forward and asked. "What's the matter, General."

Han Xin didn't answer, just strode away, leaving without looking back, but the corners of his eyes were a little moist.

"An era has come to an end." He said to himself in his heart.
