Although the shield soldiers can effectively defend against attacks by archers, they can only play a frontal defense role. The attack range of archers is not limited to the frontal. They can use large-angle shooting to attack the people and horses of the Sima army's rear team. Unless the Sima army can have a shield, it will be difficult to reach this omnipresent rain of arrows.

The archers and cavalry fired thousands of arrows at once, and the scene was naturally spectacular. The arrows in the sky were like locusts, covering the sky. The originally bright sky became a little dark, and people in Sima's army kept falling down.

Chen Qian had no choice. After all, the shield cannot be used as one, and many soldiers without shields are easily shot. However, the solid shield formation composed of sword and shield soldiers can effectively resist the attacks of archers, which made Chen Qian very excited. Using the long spear formation to fight against light cavalry and the shield formation to deal with archers is simply a perfect match. As long as the Sima army can skillfully switch the defensive formation, it can fundamentally defend the Bingzhou cavalry.

When Deng Ai saw that Sima's army was placing shield troops again, the attack effect of the archers was greatly reduced, so the archers retreated slightly and gave up the positions of the two wings, allowing the light cavalry to launch another attack.

Although the shield formation is effective in defending bows and arrows, it becomes useless to attack the light cavalry. The light cavalry is fast and sharp. With one knife, it can split Sima Jun’s wooden shield into two halves. Without a shield, the sword and shield soldiers only have a ring-headed sword left in their hands.

Not to mention that the ring-headed sword is not as long and sharp as the Bingzhou saber, even if it is an equal weapon, the Bingzhou cavalry can easily split Sima soldiers and others into half by relying on the inertia generated by the high-speed running of war horses.

After the light cavalry rushed up, the shield formation was suddenly destroyed. Chen Qian quickly ordered the shield soldiers to retreat and the spearmen to take them up again.

In fact, the transformation of the formation must be changed according to the attack method of the Bingzhou cavalry. The spear formation can target the light cavalry, while the shield formation can effectively deal with the archers, but if it is reversed, the two formations will become vulnerable.

What Chen Qian is doing now is how to make appropriate switching between the two formations.

However, the speed of the Bingzhou cavalry was far greater than that of the infantry. They charged forward like a whirlwind. Only when they got closer could Sima Army identify which army it was. At this time, it would seem a little hurried and panicked when switching the formation.

Of course, the main reason is that Sima Jun lacks training in formation conversion. These two formations that respond to the enemy were temporarily thought out by Chen Qian. How to make these two formations skillfully change to deal with the different attack methods of the Bingzhou cavalry is really a headache for Chen Qian.

Tens of thousands of people interspersed and changed positions back and forth, which is not a simple matter in itself. In addition to the consistency of command and coordination, the requirements for the formation of soldiers are also relatively high. Only after all the personnel of the entire formation are all present can this formation achieve the best effect.

But now the attack in Bingzhou is like a fish in water. Their light cavalry and archers took turns to fight, constantly attacking the Sima army's positions. When encountering a mutually restrained formation, they immediately avoid fighting. When encountering a formation that can be restrained, they rushed forward and slashed and killed them, shooting arrows, killing the Sima army hard to resist.

The Sima Army was exhausted. They had no idea which army of the Bingzhou Army would launch an attack, so they could only re-arrange their formations according to the situation. Such a lagging defense model naturally caused them to suffer heavy losses in the face of the Bingzhou Army's attack.

Chen Qian was helpless in this regard. Although both formations have advantages in responding to the enemy, their disadvantages are also obvious. If they cannot switch easily and easily, each round of attacks by the Bingzhou Army will cause them to suffer great losses.

Although there are not many casualties every time, the Bingzhou army's attacks are constantly, and the number of casualties is quite considerable.

Chen Qian had no choice but to compete with the Bingzhou Army, so he could only fight and retreat. At the same time, he asked Sima's army to send some reinforcements to strengthen the defense capabilities of the rear guard troops.

The Sima Division is also very troubled now. The Bingzhou Army's mobility is too strong. They not only attacked the broken rear troops, but also used roundabout encirclement on the left and right wings of the Sima Army. In this way, the left and right wings also face the risk of being attacked, making the Sima Division afraid to take the defense of the two wings to reinforce the rear team. Once the central army is directly exposed to the attack range of the Bingzhou Army, the entire army may collapse.

The method of shrinking troops that Sima's army used before was the most effective. When the pack of wolves was surrounded by wolves, dispersing troops was equivalent to seeking death. When 100,000 people were hugged into a group, even if the periphery was bitten by wolves, it could at least ensure that the main force would not suffer too much losses.

Now Sima Shi's goal is to persevere in Anyi. As long as he can enter the city, the embarrassing situation where he is chased by the Bingzhou army and is not as powerful as fighting back.

However, the continuous attacks of the Bingzhou Army made Sima Army exhausted from dealing with it, and the speed of the march had been greatly reduced. It had been four days since the journey of more than 200 miles, but it had not arrived yet, which made Sima Shi very anxious.

Every time this field battle is delayed for a moment, countless Sima soldiers will be killed in battle, and they will be consumed continuously, which will not only cause losses to the soldiers, but also make the Sima army even more tired.

This is obviously not a good thing. The attack method adopted by the Bingzhou Army is obviously nuisance. Their attack did not use the method of giving all their strength and killing people in an instant, but instead adopted the roundabout attack. Each attack seemed very casual and took a bite and left, which was not too much loss. However, if you bite it, Sima Shi would also hurt.

The Bingzhou Army's attack method was naturally arranged by Cao Liang. With the current attack capabilities of the Bingzhou cavalry, it is not impossible to launch a large-scale general attack, and it will destroy the Sima Army in an instant.

Although this kind of attack method can end the battle as quickly as possible, the 100,000 Sima Army is not made of paper and mud. If the trapped beasts still fight, the Bingzhou Army will also pay a huge price for the combat power that explodes in the desperate situation of life and death.

Of course, Cao Liang did not want his army to suffer major losses when attacking the enemy, so he asked the army on the front line to fight without killing the Sima army at once, consuming its strength little by little, and dragging them down little by little, just like a cat and a mouse, only after playing enough will it be eaten.
