When the army is dispatched, it is not a swarm of people rushing forward together, but there is a strict method of marching.

According to the system handed down by the current Bangwei Mansion, the method of marching should be divided into four parts: Xingjun, Heel (zhǒng) Army, Great Army, and Division.

The so-called Xingjun is often said to be the vanguard troops, mostly composed of light cavalry, with strong mobility capabilities, they are divided into several units, several miles apart, responsible for detecting the enemy in front of them, and transmitting military information.

Li Xin's army consisted of 500 men, of whom 200 were on strong horses, wearing short armor and tight trousers, with leather crowns on their heads, and bows and arrows hanging on their horses, and they were the most elite part of this strange army. The remaining 300 men were unarmoured soldiers who were convenient for movement in the mountain valleys.

After the Xingjun, there are nearly 3,000 heel troops, all wearing only leather armor, following the Xingjun a few miles behind the Xingjun, once the Xingjun in front of the Xingjun finds the enemy's traces, when the information is transmitted, the heel army will quickly move forward, if the enemy is small, it will be defeated and destroyed, if it is the enemy, it will buy time for the army.

The army after that had the largest military strength, and it was also the place where the flag and baggage were located, so it moved a little slowly.

As for the division, a group of soldiers and horses is placed on each side of the army, and they march parallel to the central army, which can cover the flank of the army, or chase the dead and chase north when the battle is won, as a mobile force.

It is divided into four parts, which cooperate with each other and correspond to each other, which can be called complete.

And the thousand people where Zhao Tuo was located were included in the heel army, and the chief general of the heel army was the captain Huan Zhao.

"Ah Tuo, I quietly heard Tun Chang say that among the four departments, the easiest ones to make meritorious contributions are the Xingjun and the Heel Army. However, it is too dangerous to rejuvenate the army, but the heel army can attack the enemy and retreat, but it can hold on and wait for the support of the army, and it is not easy to assign to this position if it is not a general's descendant. I don't think General Li values you, so he assigned us to the heel army? ”

The black buttocks followed behind Zhao Tuo, and said mysteriously while walking through the mountain road.

Zhao Tuo's heart moved, remembering Li Xin's previous encouragement to himself, but he still shook his head and said: "Hugh has to talk nonsense, the general will not show favoritism to a pawn like me, if what you said just now is spread, I am afraid that you will be dealt with by military law." ”

"Don't say it, don't say it."

The black buttocks shrank his head, but those slippery eyes showed that he didn't believe Zhao Tuo's words.

Zhao Tuo didn't bother to pay attention to him, because under the guidance of the guide, the valley road they had been traveling on finally reached the exit.

In front of you is an open riverbank wetland, and a few dozen meters ahead is a river flowing southeast.

Nan Yi Shui!

There are three so-called easy water people in the world, namely the south easy water, the middle easy water and the north easy water.

Nanyishui is located at the junction of Yan and Zhao, is the natural defense line of Yan against Zhao, several generations of Yan kings have built the Great Wall stretching for 500 miles along Nanyishui to the southeast, consolidating this line of defense, not only to defend Zhao, but also to resist Qi to the north.

Now that the Yan Dynasty coalition army took the initiative to abandon this strong defense line and crossed the Yishui to engage the Qin army, I don't know what the Yan kings who built this Great Wall would have on their faces when they learned of this.

However, Zhao Tuo at this time couldn't control this, because the military order came.

As the cavalry in front of the army returned, there was a commotion in the front of the heel army, and then, a thousand-person array at the front accelerated its pace and followed the cavalry to continue northward, while the thousand people where Zhao Tuo was and the thousand people at the rear of the hall stayed in place.

Lu Baijiang walked over from the front excitedly, conveying the upcoming mission of their team of 100 people as he walked.

The first part of the Xing army had already crossed Yishui in shallow water a few miles to the north, and the thousand men who had left before would also cross the river and feint to attack that section of the Great Wall, attracting all the Yan troops stationed on the nearby Great Wall.

And the remaining two thousand men have only one mission, to capture the section of the Great Wall on the opposite side that has been diverted troops!

Zhao Tuo glared at the black buttocks, this guy just said that the heel army is easy to get credit, this is true, their team is quite easy, but the thousand people in front of the feint attack are afraid that there will be heavy casualties.

"Shiwu is connected, obey the command, don't chase the enemy easily, don't grab the head!"

General Lu Bai once again announced military discipline, and after speaking, the two commanders also emphasized again, especially for those new soldiers who had just joined the army.

There is no way, for officers above the rank of commander and 100 generals, if they want to be promoted, what they need is collective combat merit, not a single head.

And there is one of the most perverted rules, which is that the number of beheadings must be greater than the number of deaths of this centurian.

If more people die than they are beheaded, let alone upgrade, they will have to accept punishment.

In fact, the same is true for the pawns in the Shiwu, if the number of deaths in the same Shiwu is more than the number of beheadings, not only will it be useless, but it will also be punished.

Therefore, General Lu Bai must emphasize many times, for fear that those stunned young people will blindly rush to kill for the sake of people.

Not only did he ignore the robe, but if he accidentally gave away his head, his fellow Shiwu would have to kill one more enemy to compensate for it.

Of course, it is impossible to generalize about different situations, such as the first to board the dead, or the thousands of pawns who just feinted as bait, and the credit algorithm is different.

"Everyone must not run around, listen to my orders, rush when you should rush, don't chase and kill easily, and don't retreat without permission!"

Zhao Tuo also announced it to the people of Gengshi.

Among the ten people, Zhu and Xi Qigu had been on the battlefield, and the two of them bowed their heads slightly, and their faces were a little pale.

Black Buttocks and Xiaobai were a little excited, especially Black Buttocks, who actually began to lick their lips.

The long and short brothers' eyes wandered a little. There was fear in Ah Niu's eyes.

As for the stones, he had always been expressionless and did not speak.

Only Shiruma nodded at Zhao Tuo, and the light in his eyes seemed to say, I listen to you.

At this time, there were already shouts of killing floating down the wind from the north.

If you look closely, the beacon there is already lit with wolf smoke.

"Crossing the river."

The main general Huan Zhao ordered, and Zhao Tuo's thousand-man team and the thousand-man team in the rear began to wade across the river.

Although the Nanyi Water is wide, it has just opened spring at this time, and it is still in the dry period in the north, and there is a special guide to lead, and the location chosen is the shallowest part of the riverbed, and people and horses can wade through the water.

As soon as Zhao Tuo stepped into Yi Shui, a chill suddenly spread throughout his body, making him shiver.

"Mother, this water is so cold."

The muttering sound of the black buttocks came into his ears, making Zhao Tuo want to laugh.

"Don't complain, pay attention to your step, follow the person in front of you, don't step into the pit, you may not be able to pull it out if you fall into it."

Zhao Tuo instructed again that although the depth of this section of the river was only near the knee, there were actually dark pits underneath.

He could see someone stepping into the pit just now, and if it weren't for the people in the same group who immediately stretched out their hands and pulled it, I am afraid that they would have lost their lives before the battle.

"Uh-oh."

Black Buttocks shrank her head in fear, causing Xiaobai who was following behind to laugh.

Fortunately, everyone waded through safely.

Two thousand heel troops crossed the river smoothly and appeared in front of them.

It is a ten-meter-high Yannan Great Wall!
