Sima's army was advancing very fast and soon approached Qi County.

Because Sima Yi suffered from the repeated misfortune of division of troops, this time he concentrated 70,000 cavalry together and did not give his opponents a chance to defeat them.

But no matter how concentrated it is, it is impossible to squeeze the 70,000 troops together. This will make the team bloated and lose the mobility of the cavalry.

Therefore, in terms of placing troops, the Sima Army's cavalry was divided into seven independent combat sequences according to the organization of each battalion, with about 10,000 people in each battalion, maintaining a certain distance between each other, and the distance is not too far, and it is basically within a range within the sight.

This arrangement not only ensures the vitality between the various troops and does not make the team crowded, but also has a natural advantage in coordinated combat. At the speed of the cavalry, as long as it is within the range of sight, it can basically ensure that it can arrive quickly. No matter which battalion of troops is attacked by the enemy, they can react as soon as possible and reinforce at any time.

The seven cavalry battalions basically adopt a diamond-shaped distribution, with a cavalry battalion in front, and a cavalry battalion on the left and right flanks. There is also a cavalry battalion in the rear wing position. In this way, the four cavalry battalions are distributed in four directions, front, back, left and right. The core of the entire team is a central army composed of three cavalry battalions. The three cavalry battalions of the central army are also distributed in a font shape. Once the cavalry battalions on the periphery are attacked, they can also implement reinforcements as soon as possible.

Such a flexible cavalry attack cluster was also built by Sima Yi. After learning that the Bingzhou Army had stepped up the training of the new cavalry formation, Sima Yi also improved the previous cavalry formation. The most prominent feature was that it abandoned the previous parallel attack formation and used the diamond-type battle formation, and arranged the most elite cavalry battalion to serve as the attack group in the sudden attack group. The peripheral battle group and the central army's support group support each other to form an organic and coordinated combat group.

Moreover, the biggest advantage of this diamond-shaped battle formation is that it has changed the previous cavalry's relatively rigid attack method during combat, and only knows how to rush around. After adopting the diamond-shaped battle formation, the elasticity between the various troops has increased. This formation can be expanded or contracted, and according to the needs of the battle, it can also be changed into other formations in a timely manner.

Sima Yi has devoted all his efforts to this Northern Expedition. This is why he insisted on accelerating his march despite the unfavorable destruction of food and supplies for the cavalry. Although withdrawing is a perfect solution, the blow to the morale of the army after withdrawing will be extremely serious. It can even be said that if you want to organize an attack, it will take a long time. Sima Yi doesn't want to wait anymore. He must fight and decide quickly and solve Cao Liang's major concern as soon as possible.

Sima Yi crossed the Yellow River north in February in early spring and kicked off the attack on Bingzhou. He originally thought it was a battle of tyrannical destruction, but unexpectedly, he had fought for more than a month alone, and so far, he still made any progress, which made Sima Yi, who had always been known for his calmness, secretly couldn't hold back.

This time when Sima Yi raided Qi County, he decided to fight to the death with the Bingzhou cavalry. As long as he defeated this main force of the Bingzhou army, the Sima army could directly attack Jinyang and completely quell the Bingzhou rebellion.

Retreat before the battle was definitely not what Sima Yi wanted to see. Relying on the overwhelming advantage of the number of cavalry in the Sima army, he was determined to solve all problems in one battle.

The flat Fen River Plain is endless. From here, you can reach Jinyang directly to the north. In other words, there is no barrier between fighting from here to Jinyang. The only thing that can prevent Sima's army from advancing is the cavalry of the Bingzhou army.

After entering Qi County, Sima Yi ordered the speed of the cavalry to slow down, but instead sent a scout cavalry to go out everywhere to search for traces of the Bingzhou Army. Although the plains did not hide the troops well like mountains and hills, the area here was wide. If the Bingzhou Army wanted to hide it deliberately, the Sima Army would still need to spend some time to search.

Sima Yi ordered the expansion of the range of the diamond-shaped battle formation and stretched the left and right wings ten miles away, so that it would be convenient for Sima's army to search. As long as the Sima army passes, there was almost no possibility of Bingzhou army hiding.

At this moment, the right wing of the Sima Army was suddenly attacked by the Bingzhou Army. A cavalry of the Bingzhou Army rushed towards them at an incredible speed, and in a very short time, it tore up the Sima Army's defense line.

This Bingzhou cavalry was naturally the Knight Battalion led by Wen Qin. He was ambushed on the path that Sima Army must pass early. However, Wen Qin did not adopt the idea of ​​colliding with the Sima Army head-on. The vanguard cavalry led by Hu Fen was naturally the most elite force among the Sima Army's cavalry. Although the head-on battle may not be afraid of him, fighting is not an act of impulse, and the result of fighting may be both defeated.

Therefore, Wen Qin considered to start from the weak links of Sima Army. Generally speaking, the auxiliary corps with the left and right wings as the vanguard must have a slightly inferior combat effectiveness, so Wen Qin chose to take action here.

The main reason why we chose the right wing instead of the left wing is that the Sima Army went north through the Fen River, and the Sima Army's left wing is the Fen River. The combat range here is narrow, which is not conducive to the troops' detours. Therefore, Wen Qin's first choice for attack was naturally the Sima Army's right wing.

Once the attack was launched, the speed advantage of the light cavalry immediately broke out. The cavalry of the cavalry camp had just entered the sight of the Sima army. Before they could make corresponding adjustments, the cavalry had already reached the Sima army's approach. The speed was so fast that it was shocking.

The Sima Army was originally in a state of marching. In the state of marching, they were maintaining a forward formation. At this moment, they were suddenly attacked by Bingzhou, and it was attacked from the flanks. They had to change their formation to fight.

It’s not that Sima Jun’s reaction was slow, but that the speed of the Cavalry Camp was too fast. From their appearance in sight to their contact between the two sides, Sima Jun’s cavalry felt that it seemed that only a few breaths had passed. This speed was simply too perverted and incredibly fast.

The leader of the Sima Army's right-wing cavalry battalion was Man Bing, the second son of the famous minister Man Chong. He did not seem to have expected that the Bingzhou Army would be so bold that it would dare to launch a sneak attack on them here. He was furious and ordered the entire right-wing battalion to respond, and warned the central army to find out and request reinforcements.
