The reason why Fusu urgently summoned Meng Tian to return to Xianyang was that Xianyang successively received urgent military reports from the border guards Xin Sheng and Li Xin, Xin Sheng sent that the 100,000 troops of the Yue clan were coming to attack Longxi, and Li Xin sent that hundreds of thousands of Xiongnu troops who had been silent for more than ten years were heading south.

On the occasion of the eventful autumn of the Central Plains, Hu Lu came to attack, Fusu suddenly panicked, and originally planned to lead the border cavalry to meet Hu Lu in person, but due to the strong opposition of Wei Yi and other ministers, the final compromise strategy was to summon Meng Tian back to Beijing to discuss.

On the night when Meng Tian arrived at Xianyang Palace, Fusu's study was filled with Fusu, the head of Fusu, and the chief Meng Tian and Wei Yu on the left and right.

Fusu briefly talked about the information of the border pass, and then put forward his own suggestions: Meng Tian was appointed prime minister and general to lead the government and military affairs, and Fusu went to Longxi to command the cavalry to fight against the enemy who came from the Yue clan.

Meng Tian thought for a moment and said slowly: "Your Majesty is no longer the eldest prince of the past, at this moment, the safety of the world is at stake, and the danger of the military formation should never be mentioned again." The minister recommended himself to the border pass to lead the army to defeat the enemy, and His Majesty sat firmly in the capital to town Sheji. ”

Fusu said anxiously: "Aiqing leaves Guanzhong, how to deal with the war in the Central Plains?" ”

Meng Tian analyzed: "Han Xin already has a strategy to break the enemy in the fierce battle of Xingyang, and he will break the enemy army in a few days, so the Xiangliang rebels in the old land of Qi have Zhang Han to deal with it, even if they can't annihilate the enemy, they can control it and not expand the trouble." After Han Xin broke the enemy, Wang Li could be ordered to hand over the defense of Hangu Pass and go out to guard Xingyang, and Han Xin led his army to aid Zhang Han and let Han Xin control Zhang Han's army. Han Xin has the talent of a general, and His Majesty can entrust the command of the world's soldiers and horses. ”

Wei Yu, who had been silent, said: "Your Majesty's military and political work is very hard, can the general have great talent to recommend to assist Your Majesty?" ”

Meng Tian thought for a while before he said: "Han Xin is extremely utilitarian, he can entrust the military power in times of war, and after the world is stable, he can only retain his false name and high-ranking officials. Dun Weak and Yao Jia are world-class talents, and can assist His Majesty in governing the country's affairs, and the ministers recommended Xiao He to cooperate with Shusun Tong to serve in the post of Shaofu, Xiao He has the talent of prime minister. The matter of escorting grain and grass can be entrusted to the old general Ma Xing to supervise and take over, Li You has both military and political communication, can lead the Xianyang Order to defend Kyoto, and the old general Yang Duanhe has the ability to coordinate the distribution of the whole army, and can assist the military affairs of the Prime Minister of the National Captain. ”

After listening to Meng Tian's analysis, Fusu's spirit was shocked: "Okay! With a bang, Fusu understood that Meng Tian did not recommend the children of the Meng family. He paced for a while to draw up his will: Meng Yi suddenly weakened Yao Jia into the study to assist in the administration, Feng Quji took charge of the prime minister alone, and sent Ziying (Ziying is the son of Fusu, who has a great strategy and the ability to govern the country) to pass the order to Han Xin, and at the same time arrange for Ziying to accompany Han Xin as a supervisor. The rest of the personnel deployment was all in accordance with Meng Tian's suggestion, and Meng Tian was officially promoted to general to command the world's soldiers and horses.

At the morning meeting the next day, Fusu issued the will drawn up last night, and the court applauded. Fusu confined Li Si in the palace and generally removed him from his post as prime minister, and only accompanied Fusu as Fusu's personal assistant to deal with all government affairs.

Li You was still reused by His Majesty the Emperor when his father committed the great crime of the Nine Clans, and he was grateful, and he secretly vowed in his heart to serve His Majesty and be loyal to the death.

Although Meng Tian was already a general in the hearts of the generals of the whole country, when he was officially appointed as a general at this moment, the morale of the whole army was still greatly improved.

Xin Sheng and Li Xin are also relieved and envious, although they are the same age as Meng Tian, but Meng Tian's strategy and ability are not inferior to Wang Qian, and they are extremely admired in their hearts.

For the peace of the northwest of Great Qin, Meng Tian was promoted to general and led the 100,000 troops of the Lantian camp and a large number of crossbow arrows and Qin crossbows to aid Longxi.

(Note: Fusu ordered the construction of Afang Palace and Lishan to be stopped, saving a lot of wood and other materials, and a lot of Qin crossbows and crossbow arrows were made in Xianyang.) ）

When Meng Tian led the army to the Longxi border pass, the Yue clan had been besieging Longxi for more than a month, but the old general Xin Sheng commanded well, and ordered 20,000 defenders to hold the city. Since the Yueshi were nomadic and mainly cavalry, they were not good at attacking cities, and in addition to the advantage of bows and arrows, they did not pose much threat to the defenders.

Meng Tian decided to use the strategy of luring the enemy to gather and annihilate, taking advantage of the enemy's ignorance that his reinforcements had arrived, so he prepared to let Xin Sheng pretend that he could not hold the city so that he could break through, and wait for the enemy army to enter the city and ambush a large number of crossbowmen to annihilate it at once.

Xin Sheng was very shocked when he heard this plan, and felt that this plan was too risky, the enemy army was 100,000 cavalry, once the defeated city was controlled, the whole army would be destroyed, and Xianyang would also be threatened by the iron hooves of these Hulu.

The generals He Mengtian argued for a whole hour, and Meng Tian finally persuaded the generals, which is also Meng Tian's strength, with eloquence, and at the same time he will also learn new tactics, and Han Xin has been with him for more than a year, and found that Han Xin's tricks are very beneficial.

The next day, the Yue's army continued to rumble and attack the city, and the Qin army defending the city on this day kept "falling", and it could not be supported in less than two hours. By noon, Yue's door-smashing car finally crashed through the city gate that had been blocked with stones.

After holding it for more than a month, the Hu Lu finally raised their eyebrows, so 100,000 cavalry frantically poured into the city to chase and kill the Qin army everywhere. The chase in the city is a different scene, because the Qin army has lived in the border passes and cities for a long time, and is familiar with the terrain, the cavalry of the Yue clan can't be killed.

In order to prevent the reinforcements of the Qin army from coming to seize the city, the Yueshi Shan Yu Kunyue ordered the city gate to be closed and began to loot the border Qin people in the city in batches.

After half an hour, all parties came to report, but not a single figure in the city could be found, and the soldiers and civilians ran away, Shan Yu was even more depressed, so he asked: "Then what about the Qin army that you chased and killed for a day?" ”

Before the herald could reply, they heard a desolate horn sound in all directions, followed by the familiar sound of Qin crossbow arrows in the dim night sky......

The sudden appearance of crossbow arrows made the Yue's army panic immediately, but it was not easy to unify the Yue's Shan Yu after all, although he knew that he was in an ambush or calmly ordered: "Our army is far more than the Qin army, don't panic the warriors of the Dayue Clan, ride on war horses and rush to kill them, kill all the Qin army, Guanzhong is our horse ranch." ”

The panicked Yue cavalry slowly became orderly and began to prepare to rush and kill, but they found that except for crossbow arrows flying from all directions and causing the comrades around them to keep falling, they didn't see where the Qin army was at all!!

After an hour of indiscriminate killing, leaving more than 10,000 corpses behind, the leader of the Yue clan finally found that the southwest direction had the most crossbow arrows, and slowly saw the torches, so he ordered the whole army to kill them.

After chasing less than a mile, he finally approached the place where the torches were, and found that it was at the end of a large avenue to the southwest, near the city wall. So Hulu's cavalry rushed over even more frantically.

At this time, the 50,000 crossbow arrows that Meng Tian had already arranged blocked the nearly 90,000 Yue's cavalry in a fan shape to block their back road, and instantly began to fire 10,000 crossbows in unison, which was the overwhelming crossbow arrows pouring in.

After five rounds of crossbow arrows, Yueshi left more than 20,000 corpses, only fortunately his own soldiers surrounded it and used their bodies to resist the crossbow arrows did not fall, he found that his army was deeply encircled, but also understood that the reinforcements of the Qin army had arrived, the general trend had gone, in order to save his life, he hurriedly ordered the whole army to withdraw closer to the west gate at all costs.

There were still more than 50,000 people in the remnants of the army, and when they ran to two hundred steps away from the west gate, countless torches were lit up on the city in an instant, followed by countless rockets shooting from the city, and the leather jackets on many cavalry were burned immediately. Shan Yu couldn't care so much, and ordered the whole army to break through the city gate and rush out. When half of their military horses rushed out of the city gate, the sound of Daqin's crossbow arrows sounded in front of them, and this density was not much different from the ambush circle at the southwest corner of the wall just now.

To make them even more desperate, the city was full of people, and it seemed that many crossbowmen were ready. Shan Yu completely understood that the generals of the Qin army had already arranged his route, and after the first ambush, he was forced to run to Ximen, and this time he was going to completely put them to death.

In less than two quarters of an hour, half of the Yue's cavalry out of the city was swallowed up by the crossbow arrows that had been waiting outside the city for a long time, and the more than 20,000 horsemen in the city could not get out at all, because the rockets on the head of the city never stopped, and the crossbow archers who had just been ambushed in the southwest corner also came from behind.

Just when Yue's Shan Yu Kunyue was about to kill himself with his sword, the torches on the head of the West Gate City were brighter, and a large banner with the word "Meng" was hung, and the soldiers stopped shooting. At the same time, the interpreter of the Qin army began to shout to the desperate Yueshi cavalry: "Please the knights of the steppe dismount and surrender, and Great Qin will not kill the prisoners." ”

After shouting many times, Shan Yujian had no hope of breaking through, and he also understood that it was Meng Tian who came to help, and he was far from being Meng Tian's opponent, and he also knew the story of Meng Tian's massacre of more than 500,000 Hun cavalry more than ten years ago. With a single order, all the Yueshi cavalry dismounted and surrendered.

The next day, the inventory of the battlefield was completed, more than 50,000 horses were captured, and more than 20,000 captured Yueshi cavalry were detained separately, and the horse exploration express: The 300,000 troops of the Xiongnu went south to the Yueshi royal court, and the Yueshi royal court was captured except for a few people who fled, and the Xiongnu had retreated north.

Yue Shan Yu Kunyue received this bad news and also saw the tokens and some of the heads of his family members, fainted twice, vowed to serve Great Qin, and pleaded with Meng Tian to avenge them.

Meng Tian was about to train the newly arrived 100,000 troops into cavalry, and when he received the allegiance of Yue Shan Yu Kunyue, he was very relieved and immediately agreed. At the same time, Meng Tian played Fusu: Ren Yue's clan was the king of Xijun in Kunyue, and the original Yue's hometown was his fief, but he could not return to the fief, so the king of Xijun led more than 1,000 old troops to the Jiuyuan military camp to train the 100,000 new troops brought by Meng Tianxin as cavalry. The 20,000 Yueshi cavalry who surrendered were left with 5,000 to be incorporated into the Longxi Army, and the rest were brought back to Xianyang by Meng Tian for another call.

Fusu played one by one, so that the situation in the grassland in the northwest came to an end for the time being, and the attack of the Yue clan also made Meng Tian completely resolved.

A few days later, Meng Tian returned to Xianyang and continued to command the world's soldiers and horses to quell the chaos.
