The tactics of horse harness, forging body, and archers and flying kites quickly spread throughout the army, and as the founder, Yang Yifei's name quickly spread among the army.

You must know that Yang Yifei's dedication of horse harnesses, innovating training methods, and creating new tactics is not only about strengthening the country and the army, but also for the soldiers of Great Qin, it also improves their survival chances and can effectively reduce the casualty rate, which is closely related to them.

And Yang Yifei was promoted from Yijie Li Shu to the twelfth rank of Zuo Geng in just two and a half months without being on the battlefield, which also became a legendary experience, which was widely spread in the army and inspired the soldiers of Daqin to work hard.

To put it in a more fashionable phrase, Yang Yifei became the star general of Daqin.

It's just that the other troops started later than the Mengjia army after all, and when the horn of war sounded, the archers of the other units had just been formed, and they had not yet been drilled, and they had not yet formed combat effectiveness for the time being.

It is because of this expedition that Yang Yifei's curved archer cavalry is the only one, and all the troops participating in the battle will witness the glory of the archer cavalry troops.

In the third month after the first emperor observed the new tactics, the military information came from the border pass, and Di Rong, such as Qiang, Yueshi, and Wusun, gathered an army of 200,000 and invaded the two counties of Longxi and Beidi in Daqin.

Longxi County is close to Beidi County, covering Tianshui, Lanzhou, Ningxia, Qingyang, Pingliang, Guyuan, Jingzhou and other areas in Gansu Province in later generations.

These two counties are located in the upper reaches of Weishui, only 600 miles away from Xianyang, the capital of Daqin, the geographical location is very important, it is a place where soldiers must fight, if the two counties of Longxi and Beidi are breached, Xianyang is in danger.

In this era, the total number of Qin troops is about 900,000, of which 300,000 are led by Meng Tian and Fusu, stationed in the north, and are responsible for presiding over the construction of the Great Wall to resist the Xiongnu, the main enemy of Great Qin.

400,000 led by Ren Huan, Zhao Tuo and other generals, stationed in the south, while deterring the remnants of Baiyue and Yelang and other barbarians, they made every effort to develop the southern region.

150,000 are distributed in the western and northwest border towns, responsible for defending against the Western Regions, the east is the sea, and there is no need to consider the enemy from the sea in this era, there are not many troops stationed in the east, and most of them are county soldiers recruited by local officials themselves, and the main role is to clear out bandits.

The remaining 50,000 are the most elite Xianyang garrison of Great Qin, and the 30,000 Mengjia army is the elite of the elite of the Qin army, and it is the sharp blade of the country of Great Qin.

The other 20,000 garrisons are commanded by a general named Xu Gui, whose main responsibility is to guard Xianyang and protect the safety of Xianyang Palace.

There were 50,000 border troops stationed in Longxi County, and the Mengjia army received an edict from the First Emperor: immediately rush to the frontier and cooperate with the border soldiers to defeat the invading enemy.

Yang Yifei actually didn't understand why the First Emperor had to place the capital in Xianyang, which was so close to the frontier, because the territory of Great Qin was so large.

Perhaps this is also a kind of self-confidence and conceit of the first emperor! He firmly believed that Di Rong would never break through the defense line of the Great Qin Border Army and advance to Xianyang.

Of course, he should indeed have such confidence, and it turns out that not to mention that when he was alive, it was many years after he was in Bintian, and Di Rong of the Western Regions had never stepped into the territory of Great Qin.

Therefore, 50,000 border troops plus 30,000 Mengjia troops, 80,000 horses and 200,000 enemy troops, the first emperor's edict was the word "defeat", not "resist".

……

In the camp of the Mengjia army, Meng Yi stood on the platform of the generals, his eyes swept over the soldiers under his command who were ready to go, and their morale was high, and he shouted loudly: "Soldiers, since I destroyed the six countries of the Great Qin and unified the world, I have attacked the Huns in the north and Baiyue in the south. ”

"Now that Di Rong has come from the west, invaded my frontier, invaded our land, and poisoned the people, this general asks you, what should you do?"

"Kill, kill, kill"

The soldiers shouted three times in a row, and when the shouts of killing fell, Yang Yifei, who was riding a war horse and standing at the forefront of the archers, suddenly raised his fist and shouted: "Those who offend my Great Qin will be punished even if they are far away." ”

As soon as he spoke, the archers behind him immediately shouted fanatically: "Those who offend my Great Qin, even if they are far away, they will be punished...... Those who offend my Great Qin will be punished even if they are far away......"

Hearing their words, the other troops also spontaneously shouted: "Those who offend my Great Qin will be punished even if they are far away......

This was Yang Yifei's impromptu idea, and he had never "rehearsed" in advance, because at the beginning, the voices of the soldiers were not very even, and they shouted one after another.

After shouting a few times, everyone's voices finally rang out, but this short sentence made all the soldiers enthusiastic, and their morale suddenly reached its peak.

Meng Yi and Nangong Yan behind him looked at Yang Yifei with admiration in their eyes, what a "Whoever offends my Great Qin, although he is far away, he will be punished", this sentence will definitely go down in history.

"Qiang"

After the soldiers shouted nine times in a row, Meng Yi drew his sword out of the sheath, Huo Ran stabbed obliquely into the western sky, and the field immediately fell silent, leaving only Meng Yi's voice echoing in the Mengjia army camp: "Mengjia army, go to battle." ”

The various tribes stepped out of the camp in an orderly manner, and the black torrent rushed towards the west, and the western Dijon would eventually pay the price of blood for their stupid act of violating Great Qin.

……

Yang Yifei is the first time to lead troops in the real sense, in the Luding world, he is not with the big army, basically killing a single line.

War is the best embodiment of a country's national strength, and on the march, Yang Yifei saw Daqin's powerful logistics support capabilities.

It is no wonder that Great Qin raised 600,000 troops to attack Chu State, and for two whole years, the 600,000 Qin army has never run out of food.

It turned out that before the Great Qin unified the Six Kingdoms, in order to support a large number of troops, a large number of large granaries were built, and an incentive mechanism was set up to encourage the local people to be diligent in farming, and also set up laws to protect the cattle.

After that, every time a place was conquered, it would be turned into a large granary and sent to those who were guilty to plough it.

It can be said that there are granaries everywhere in Daqin, because the grain is very sufficient, until the first emperor Bintian and Daqin perished, these granaries are still there, but they are cheaper than Liu Bang and Xiang Yu, of course, in the end, Liu Bang is cheaper.

It is precisely because of the existence of these granaries that when the Great Qin army marched, there was no such thing as "the soldiers and horses did not move, and the grain and grass went first".

As long as Daqin's logistics troops calculated the distance, and when the combat troops arrived at a position to leave the camp, the grain supervision team had already transported the grain and grass from the nearby granary.

Such a logistical support mechanism can be described as quite advanced.

In addition, the march of the army is different from the ordinary rush, because "there is no way to march, no way to invade the festival, no loss of food and drink, and no strength to stop men."

This means that the key to marching is to maintain a reasonable pace, ensure that the soldiers eat moderately, and maintain sufficient physical strength.

Therefore, "where the army marches on the road, ten miles of rest, thirty miles of dry food, sixty miles of food and lodging", that is to say, a day of marching sixty miles, it is necessary to let the soldiers eat and sleep.

In other words, the length of the march is "military time", and when to eat and when to rest, are determined by the number of miles traveled.

Yang Yifei basically didn't understand the knowledge of these ancient marches and battles, but after this expedition, he learned it.
