Yi Zong rode his horse and looked at his distant enemies from afar.

His eyes never left the big curtain for a moment.

"O ...... of the Zhelan tribe," Yi Zong stroked the sword at his waist.

During these times in Yunzhong County, he was like thunder about the name of this tribe!

The name of the Shan Yu whip of the Zhelan tribe is even more familiar.

Yizong's face was extremely serious.

"Zhelan people are the best at white-knuckle combat!" Yi Zong said to the Han army generals beside him: "They are the backbone of the Huns!" ”

"If we can interrupt them, then, from now on, my Han will be able to make the entire Huns fear and fear!"

The officers from Hu Benwei and Yu Linwei were all gearing up and eager to try, and even Sima said: "Jun Hou, please rest assured, we will definitely defeat!" ”

But the officers from the clouds were all solemn.

Those who have not fought against the Zhelan people will never know how terrible this seemingly rough and crazy Xiongnu tribe is.

This is a terrible tribe that even if it falls into a heavy siege, even if it is picked off the horse and the bones are broken, it will frantically hug anyone who comes close to it, and roll and bite on the ground together.

The weapons of the Zhelan people are not only bows and arrows, collars, and hammers.

There are teeth, fists, and feet.

A person like this is not terrible.

But ten thousand such people are demonic legions from hell, and when they are organized and disciplined, such an army is terrifying and terrifying enough to make anyone who fights them tremble and fear.

"Command the whole army, check the crossbow!" Yizong decisively gave an order through the Chinese army when he was still ten miles away from the Huns.

Orders were passed down to individual soldiers.

Except for the cuirassiers of the Tiger Ben Guard and the Yu Lin Guard.

The other Han cavalry began to check the crossbows they carried.

This kind of hand crossbow is the result of the cooperation between Moyuan and Shaofu.

It compares to the old hand crossbow. Lighter and more precise.

What's more, a crossbow case has been added, which can be wound in one time and can fire three arrows in a row.

This was crucial for the cavalry.

Of course, there are drawbacks.

That's power and range. All of them have been greatly reduced, and the effective killing distance is only thirty steps, and the best shooting range is only ten steps.

However, for the cavalry, such shortcomings did not matter.

The Han army never lacked the striking power of long-range fire projection.

The appearance of this kind of crossbow effectively strengthened the Han army's advantage in melee combat.

And. The popularity of stirrups, saddles, and horseshoes enabled the cavalry of the Han army to free their hands and do more things.

Such as......

Many cavalrymen of the Southern Army, after inspecting their crossbows, silently took the ring-headed sword in their hands.

This kind of great sword is made of iron. The blade part of the sword is extremely sharp. In the past experiments, he could easily cut off the enemy's bronze weapons, and even more easily split the enemy's leather armor and cut off his bones.

And behind the army, hundreds of chariots followed closely.

These war kings of the old era who were originally eliminated from the battlefield. In this completely new era, it has withdrawn from the main combat forces of the Han army.

They are now improvised fortifications that follow the march of the army, transporting supplies and acting as obstacles for defense.

Right now. These chariots were loaded with the equipment of the Han army.

Especially those cuirasses and cavalry guns.

"General, the whole army's crossbow inspection has been completed!" When there were still about eight miles away from the Xiongnu army, an officer reported.

At the same time, the Hun army on the opposite side also began to advance.

Yizong completely focused his attention on the movement of the Hun cavalry on the opposite side and the array moving forward.

Hearing this, he just nodded and said, "Order: Take the northern and southern armies as the left and right, and the cuirassiers as the middle army!" ”

The flag waved, and the array of the Han army also began to adjust, from the original loose formation to a closer combat formation.

When the distance between the two armies reached three miles, Yi Zong ordered: "The whole army obeys the order and stops advancing!" ”

So, when the Huns stopped their steps, the Han army also stopped almost at the same time.

Yi Zong first observed the array of Hun cavalry on the opposite side, and then sighed: "Sure enough, it's a strong enemy!" ”

The cavalry array of the Huns, in the eyes of the righteous column, was tight and aggressive.

The large oval-shaped formation indicates that the opponent is very likely to charge at any time.

And the distance is only three miles, and for the cavalry, it may only take a flick of the fingers.

Even, in all likelihood, you will not be able to react.

But this formation, in terms of defense, is also perfect.

The formation listed by the Huns made Yizong learn a lot.

"Our army is still inferior to the Huns in terms of organization and tacit understanding...... Looking at the Huns on the other side who did not need orders and coordination at all, they had already lined up the array and set up a posture, and Yi Zong sighed in his heart.

Then, he began to order.

"Tiger Benwei! Yu Linwei, the captains of each Sima, listen to the order! Yi Zong rode forward and pulled out the sword at his waist: "The whole army is armored!" ”

"No!"

So, in the center of the Han army, a pair of iron armor was pushed to the vicinity of the Chinese army by chariots.

The 2,000 cavalrymen of Yu Linwei and Hu Benwei began to put on their cuirasses neatly, fasten their buttons, put on a helmet that stood tall and upright, and took over the cavalry spears with a handle, and then, with the help of the logisticians, they put down their masks, and only their eyes were exposed.

Then they formed a dense cavalry array.

The array was so tight that from a distance, they looked like a solid wall.

Hu Benwei's Cheng Buzhi once wrote a booklet called "The Use of Cuiras", and Yi Zong himself wrote a training manual called "Battle Formation Record" based on this booklet.

In both booklets, there is a principle.

The way to charge into battle lies in the ratio of the enemy to us, not in the number of our troops.

Even, within the Tiger Benwei, there is a formula that has been summarized by several officers.

According to this formula. It was found that on the battlefield, especially when charging into battle, the maximum theoretical loss rate of the attacking side was only proportional to the number of enemies in front of them.

And not how many people there are in our army and how many people there are in the enemy.

Within a single unit area. In close combat, this formula is even more of a god-like truth.

All past drills have proved the reliability of this formula.

Because its inventor is the general of the Tiger Benwei headed by Cheng Buzhi, therefore, within Yulinwei and Hu Benwei, it is called the 'Tiger Ben Theorem' or also known as the 'Cheng's Theorem'.

This is the first time that the Han army has found a way to boost its combat effectiveness from mathematical calculations and principles.

From now on. Within Yu Linwei and Hu Benwei, there was an upsurge in the use of mathematics to serve the military.

Cheng Buzhi even wrote a textbook for crossbowmen as a textbook for crossbowmen, in which Cheng Buzhi, with the support of the Son of Heaven, borrowed from the Han mathematical institutions, including the Taishi Administration, to calculate the firepower projection strike efficiency of crossbowmen from 500 to 5,000 people in different environments and conditions.

That "The Use of the Strong Crossbow" thus became the textbook of Wu Yuan.

Now. Within Tiger Benwei and Yu Linwei, want to be promoted?

Don't understand math. That's almost impossible.

Officers above Sima level, and even everyone has a mathematician's teacher.

As the lieutenant of Yu Linwei, Yizong's mathematics score has also continued to improve - if he doesn't improve, he can't do it, in case the officers below are better than himself. Where is this captain's face placed?

You must know that in the Han army, status has always been determined by ability rather than identity.

At this moment, in the mind of Yizong. In fact, it is a myriad of numbers tumbling.

The dozen or so officers on his left and right sides were also holding a small abacus, constantly moving and calculating.

Then, a piece of white paper was handed to Yizong.

While looking at it, Yi Zong mentally compared these results with the results of his own calculations.

This is the typical style of Yu Lin Wei and Hu Benwei today.

Under the advocacy and encouragement of the Son of Heaven, the two guards of Yulin and Huben, up and down, are all prevalent before fighting, first settle accounts, before arraying, first calculate the comparison between the enemy and us, and even even charge, we must first calculate the distance and speed between our army and the enemy.

The benefits of this are obvious and practical.

Therefore, over time, even if the Son of Heaven does not supervise, everyone consciously maintains this habit.

"The number of our army and the enemy is about one to one...... At this moment, Yi Zong was repeatedly comparing the number of the enemy and the enemy, and the length and width of the enemy array: "The length of the enemy army is about five miles, and the thickness is about two miles......

Looking down at the calculation results on those blank papers, Yi indulged in his heart, and naturally many different pictures appeared.

That was the maximum blow and firepower projection area that the Huns could inflict on the Han army under various conditions.

Then, Yi Zong raised his head, raised his hand, and began to give orders to the other troops: "Southern Army A, three hundred steps forward!" ”

"Northern Army Yitun, retreat fifty steps back ......"

"Yunzhong County Jiaqu, move forward a hundred steps......"

One by one, orders were issued, and then through the order flags, they were transmitted to the corresponding troops.

The array of the Han army began to undergo complex changes.

"The chariot moves forward five hundred paces ......," the last order was given.

As a result, the array of the Han army that appeared in front of the eyes of the Huns began to become strange and eye-catching.

It was a cone-like military formation.

On the left and right flanks were the light cavalry and archers of the Han army, who were divided into a dozen large and small war groups, and the distance between them was unified at one hundred and fifty paces.

The width between each cavalry was about three paces.

From a distance, they looked like some stragglers hanging over the plains.

But in fact, anyone with a little experience knows that such a formation is very scientific.

The distance between each wargroup is just right, knocking to the benefit, and the distance between each cavalry.

This allows them to maximize their firepower and speed.

More importantly, the cooperation between each other will be more compatible, even if there is an accident, there will be no collision and mutual interference.

As for the middle army, two thousand cuirassiers formed a thick and solid array.

These cavalry are so conspicuous and so noticeable.

So much so that even if they were three miles apart, the attention of all the Huns was on them.

"Beat the drums!" Yi Zong ordered the horse.

In the rear of the Han army, the war drums carried by five chariots rumbled under the beating of dozens of big men.

The drums are very rhythmic.

Stepping on the beat of the drum, the cuirassiers of the Yulin Guard and the Tiger Benwei slowly moved forward.

"Raise your gun!" One after another roared hoarsely.

The long cavalry spears began to be raised flat, and the sharp spear heads, in rows, shimmered in the cold light of the sun.

Step by step, these cuirassiers began to advance slowly, and the trained war horses understood their masters very well.

They move forward unhurriedly, step by step.

"Wait for the right order!" At this moment, Yi Zong came to the big array on the right, and he drew his sword and pointed forward: "Southern Army Zuo Sima!" The right tun of the Northern Army! Charge out of the formation, swim to a hundred steps in front of the Hun formation, and project it with a bow and crossbow! ”

"Part A, Part C, take the back step!"

It is the duty of a soldier to obey orders!

The northern and southern armies have embed this vocation deeply in their own bone marrow.

At this time, the main force of the two Han armies guarding Chang'an was not the time of Yuan Cheng, those delicate old soldiers and young master soldiers.

At this time, the Han army also knew that there was a truth - the army had its own Yan Ruyu, and the army had its own golden house.

Young man, do you want to get rich, get ahead, glorify your ancestors, or even worship the prime minister?

Then go charge!

Everything you want, you can get through your weapons and blood and sweat.

So, with an order, two thousand horsemen rushed out of the entire Han army on the right flank.

Suddenly, the horses neighed, and the horses' hooves galloped, rolling up puffs of dust. (To be continued.) )
