Seeing that the infantry could not hold on, Kuo Duan had no choice but to take the risk and use the cavalry.

In the Song army's formation, Zhao Fan saw densely packed Mongolian cavalry coming out of the formation. The cavalry galloped, like mountains falling and ground cracking, and rolling mudslides roaring towards them. He was not happy in his heart, but looked solemn on his face.

In order to force Kuo Duan to use cavalry to charge into the formation, Zhao Fan continued to invest heavy infantry, and finally forced Kuo Duan to use cavalry.

However, his continuous dispatch of infantry also greatly weakened the defense of the Song army's originally tight formations, which may not be able to withstand the impact of the Mongolian cavalry.

At this time, the Mongolian cavalry trampled the ground with thousands of hooves, approaching like Mount Tai.

Facing the rushing cavalry, the soldiers of Song Dynasty in the military formation were beating wildly in their hearts and clenched their weapons unconsciously.

At this time, on both wings of the Song army, veterans Quan Zicai and Zhao Kui stood proudly on their horses. Looking at the Mongolian cavalry galloping over, they raised their weapons and shouted loudly, "Defend!"

The crossbowmen and archers on both sides of the Song Army immediately cocked their crossbows, and aimed their divine arm bows, foot bows, and step crossbows at the galloping cavalry.

The Song Dynasty lacked cavalry. In order to fight against the horse army of the northern peoples, the Song Dynasty militarily piled up armor to strengthen the defense of the infantry. Second, it organized a large number of long-range units to use the advantage of bows and crossbows to shoot down the cavalry.

The Mongolian cavalry galloped out of the formation and rushed directly to the front of the two flanks of the cavalry. However, when they were about to enter the range of their bows and crossbows, they made a false shot and ran towards the flanks of the two flanks of the Song army, hoping to mobilize the Song army and cause chaos in the Song army's array.

Quan Zicai was riding on his horse, and he saw nearly ten thousand crossbowmen in the formation, holding large crossbows and bows and arrows, turning as the Mongolian cavalry moved, and the arrows were always aimed at the Mongolian cavalry.

The heavy soldiers of the Song Army in the military formation shuttled through the formation and quickly mobilized to the side to strengthen the side defense.

With the roar of hooves, the Mongolian cavalry galloped over and the spearmen on the outside tightened their weapons. In the blink of an eye, the Mongolian horse army was only 300 steps away from the military formation.

"Cut the crossbow! Release it!" Quan Zi then calmly shouted the order.

In the Song army's formation, the crossbowmen who moved their arrows as the cavalry moved, immediately fired the crossbow machine.

"Swish, swish, swish!" Thousands of arrows were fired in the Song army's formation, and the arrows roared out, directly shooting into the bodies of the Mongolian cavalry and war horses.

It was thrown away and hit the ground hard, stirring up billowing yellow dust.

The Mongolian cavalry fell off their horses one after another, but the fierce Mongolian cavalry was not intimidated by the arrows fired by the Song army. Instead, they continued to pounce on the Song army's array while running, with their bows and arrows drawn.

As the Mongolian cavalry approaches, it means that they will enter the strike range of more bows and crossbows from the Song army.

In the military formation, thousands of Song army crossbowmen operated their crossbows in a uniform manner, and the scene of thousands of arrows firing simultaneously made the sky darken.

Kuo Duan stared at the battlefield with his heart bleeding. No matter how many infantry troops he lost before, he did not feel sorry for them. Those who died were all Han people, but now it was Mongolian warriors who fell.

Under the intensive rain of arrows, the Mongolian light cavalry rushing in front suffered heavy losses.

Originally, they were going to gallop thirty steps in front of the formation and then shoot their bows and arrows, but the huge casualties made the Mongolian cavalry across Eurasia become timid.

When they rushed fifty steps in front of the formation, the Mongolian cavalry hurriedly fired an arrow, then drew their horses and turned around in front of the formation. While shooting arrows, they quickly broke away from the Song army's formation.

Thousands of Mongolian light cavalry gathered at a large formation of the Song army, shooting rain of arrows. The Song army infantry holding spears fell to the ground after being hit by arrows.

The Mongolian cavalry was really powerful in cavalry shooting. Many spearmen wearing heavy armor were hit in the face by arrows. There was a trace of chaos in the outer defense of the military formation.

"Charge in!" After the Mongolian light cavalry retreated after firing, the Mongolian heavy cavalry following the light cavalry roared.

More than a thousand Mongolian heavy cavalry, with their horses hooves clattering, crashed directly into the army formation disrupted by mounted fire with thunderous momentum.

Since the heavy infantry of the Song Army's formations were drawn out to fight with Li Fen's infantry, the heavy infantry guarding the archers and crossbowmen on the outside became much thinner.

At this time, the spearmen on the outside were shot by Mongolian cavalry again, and the formation became chaotic.

The Mongolian heavy cavalry took advantage of this opportunity and crashed directly into the military formation. The outermost spearman was knocked upside down in an instant. The Mongolian cavalry was like a bulldozer, breaking through several rows of spearmen in succession, knocking the entire formation inwards.

.

The veteran Quan Zicai immediately shouted: "Attack from both sides!"

The Mongolian heavy cavalry continuously broke through the spear formations of the Song army. While knocking away the spearmen of the Song army, they were also stabbed to death by the spears and gradually lost their impact.

Quan Zi just gave the order, and the Song Army infantry who had been knocked away heard the drum trumpets and immediately surrounded them from both sides and attacked the Mongolian cavalry who had entered the formation and lost speed.

The Song army came up from both sides, stabbing the cavalry with their spears and stabbing the horses. They knocked the Mongolian cavalry who had lost speed off their horses and then hacked them to death with random swords.

Seeing that the Mongolian cavalry failed, Kuo Duan immediately ordered, "Pull back and charge again!"

The Mongolian cavalry who was about to fall into the formation heard the sound of the horn and quickly pulled out their horses to leave the Song formation.

Quan Zicai looked at the cavalry's retreating figures and quickly ordered, "Restore formation."

The soldiers of the Song Army quickly filled the vacancies and formed a large formation again. However, they were rushed by the Mongolian cavalry and lost a lot of infantry. The outer spear formation was thinner again.

The Mongolian cavalry withdrew and quickly regrouped. Seeing that the infantry in front of them was already showing signs of defeat, the Mongolian cavalry did not dare to hesitate and soon launched another charge amidst the sound of the horn.

The battle situation on the battlefield at this time was cruel and fierce. The infantry of the two armies were fighting to the death. The Song army's infantry suppressed Li Fen's 40,000 troops, while the Mongolian army's infantry was still struggling to hold on.

On both wings, the Mongolian cavalry continued to harass and attack the Song army's flanks. South of the Huaihe River, there was already a river of blood and corpses strewn across the field.

At this time, as time passed, Kuoduan began to become restless. The Mongolian infantry in front was suppressed by the Song army. The cavalry charged into the formation and suffered huge losses, making the Mongolian army's strength smaller and smaller.

"Why hasn't Zhang Rou crossed the river yet?" Kuo Duan couldn't help cursing in his heart. He and Zhang Rou had already agreed that when he and Zhao Fan fought decisively, the Mongolian troops on the north bank would cross the river regardless of the cost.

On the Huaihe River, the Song Navy took the initiative to attack Lianshui and fought a battle with the Mongolian army at the ferry. A large number of Mongolian warships and rafts were either knocked over by the Song Navy or burned by rockets.

However, just when the Song navy attacked Lianshui and contained the Mongolian army on the north bank, thousands of Mongolian soldiers took small boats and broke through the obstruction of several Song army sentinels and reached the south bank of the Huaihe River thirty miles upstream from Lianshui.
