Xi Yuyu!

The sudden terrifying sound of war horses broke the silence under the night sky, not only issued an early warning to Cao's army, but also exposed the whereabouts of the sneak attacker hidden under the night sky...≦

"Break through the enemy camp and kill!" The war horse neighed, but saw a silver-white figure jumping forward, and a long spear flashing cold pointed directly at the Cao army camp in front. While shouting loudly, he rode his horse and swung his gun and charged forward.

"Dadadada——Kill!" The sound of horse hooves roared, and the shouts of killing resounded throughout the night sky.

With the order from the main general, the cavalry team that had originally hidden their bodies had no scruples. They rode their horses out of reins and rushed straight to the gate of the Cao army camp.

Just as they showed their figures, the Cao army patrol team, who were cruising in the wilderness of the gate, quickly gathered from all directions to try to intercept and encircle the Xiliang Iron Cavalry who suddenly came out.

In an instant, accompanied by the "booming" firelight, the Cao army patrolling the night sky lit torches and illuminated the wilderness. Immediately, a rain of arrows penetrated the night sky, and the two armies and cavalry that were jumping and diving met head-on, and the battle broke out at this moment. In the flashing and swaying firelight, a silver figure took the lead and rushed into the Cao army trying to intercept. Ten thousand cavalry followed closely followed and shot one after another, and each cluster of arrows was heading for the firelight.

"Puff puff puff puff———————————————" The sharp weapon broke through the body suddenly, followed by a shrill scream. The light of the torch exposed the location of the Cao army soldiers, and invisibly provided the target for accurate shooting for the Western Liang Iron Cavalry under the night sky. As soon as both sides encountered, the Cao army soldiers were hit by the head-on attack, and the arrows were shot without any slightest. The large-scale shooting caused the Cao army scouts who were blocking the charge to fall one after another. Sweeping the obstacles to the charge, providing the army with precious space to attack the gate.

It is obvious that this Xiliang Iron Cavalry who left the city late at night was a 10,000 cavalry team in the Wushuang Iron Cavalry Camp under Zhao Yun's tent. The Wushuang Iron Cavalry Camp has a full 33,000 people, three 10,000 cavalry teams. Among the remaining 3,000 people, one thousand are the direct personal guards under the tent of the main general and the deputy general, and the other two thousand are scouts and whistle cavalry.

During the daytime offensive and defensive battle, most of the five thousand soldiers guarding the city were injured and killed, and now there are less than two thousand soldiers in the county government who can still hold on the top of the city. At the same time, the 10,000 cavalry who reinforced the city also suffered heavy casualties. The cavalry turned into infantry defending the city, and their combat effectiveness was sharply reduced. In the end, only more than 3,000 cavalry could survive. Therefore, after defending the city in one day, Zhao Yun lost more than 10,000 infantry and cavalry under the tent, causing heavy losses.

Seeing this, Zhao Yun knew very well that Kaifeng City might not be able to defend. At most three days, nearly 40,000 soldiers in the city would wipe out the entire army and destroy the city. It would be absolutely wise to do it even though he knew it was impossible. Therefore, Zhao Yun made a decisive decision and abandoned the city and retreated. However, Zhao Yun was definitely not a person who was beaten and refused to fight back, so he decided to return the Cao army to the night attack and robbery camp before the army withdrew from Kaifeng City.

It is called the robbery camp. In fact, Zhao Yun never thought of breaking the Cao army camp in one fell swoop. After all, there are more than 100,000 troops stationed in the camp. The 10,000 cavalry he led could not shake the Cao army, and it was even more impossible to successfully robbery the camp. So he retreated to the next best. The purpose of this trip was very simple. It was just to create chaos for the Cao army. As long as it could make more than 100,000 Cao army soldiers in the gang, there was no need for him to lead the army to rush. The Cao army soldiers in the camp would trample on each other, causing huge losses. If this could be done, Zhao Yun's goal of leading the army to attack late at night would achieve his goal. Then, taking advantage of the civil strife of Cao's army, he led his army to withdraw from Kaifeng City and retreat to Zhongmu, so that he could retreat unstoppably.

Amid the sound of "clang clang" weapons, Zhao Yun led the way, with a BMW snow lion under his seat, and the magic weapon, dragon gall spear in his palm, and no one could stop him. A dragon gall spear danced so hard that it was full of wind and killing all directions. Behind him, ten thousand iron cavalry formed a charge formation of a sharp arrow, and he was the sharp blade arrow, followed closely behind like an arm to use his fingers, approaching the Cao army camp at a speed visible to the naked eye.

As he approached the camp, he didn't wait for the raids of arrows at the gate to shoot at the gate to see Zhao Yun pull up his horse and raise his dragon gall spear, shouting loudly: "The two wings are detouring, throwing fire and thunder, and dispersing!"

The ten thousand iron cavalry following him scattered and dispersed in front of the gate of the Cao army camp, avoiding the archers on the main gate and the gate tower. The archer formation instantly evolved into a "one" geese-shaped formation, and rushed straight to the walls on both sides of the gate. While the formation was dispersed, these cavalrymen took out black lumps as big as melons from the black leather bags on both sides of the horse's back. Two people in groups, cavalry holding black lumps with black lumps charge, and the other one followed closely behind, charging and raising bows while raising strings. When the cavalry in front threw the black lumps, the cavalry behind ignited the rockets and shot arrows in the direction of the black lumps. The rockets came back and hit the wooden stakes three meters high in front of the black lumps, and then the black lumps hit the wooden stakes fence wall with sparks.

"Boom——!" The black lump hitting the wooden stake exploded when it encountered fire. With a loud bang, the wooden fence wall vibrated violently, causing the defenders standing on the wall to be shocked and their minds to be lost. Two defenders even were frightened by the huge explosion, their legs and feet were weak, and their bodies were tilted. They fell from the wall, causing their brains to splash and died on the spot. The foundation outside the wall was very strong, and there were rocks or traps. They were originally set up to prevent the enemy from robbing the camp. Unexpectedly, this time it was used on Cao Jun himself. As long as they fell from the wall, they would definitely die, and no one was spared.

In contrast, the cavalry that threw black lumps did not approach the wall, but instead rode their horses and ran around and threw all the black lumps in the black leather bag. After the first black lump exploded, the black lumps thrown out from behind did not need to be ignited because the fence wall had already burned, and there was wind at night, and the flames flashed in confusion. So the second black lump could explode immediately as long as it hit the flames not far away. The effect was better than the first one. At least it was loud enough, like a thunder rumbling, which made the defenders on the wall dizzy and Venus appeared in front of them. In this case, the defenders with slightly worse psychological quality would be frightened and pissed. The mild ones were so scared that they sat on the pallet on the wall and did not dare to show their heads. In severe cases, they fell down and fell to pieces.

The Cao army camps were built by logging. In order to ensure that the walls will not deform and be more solid, these wooden stakes that build walls need to be slightly baked to remove moisture. The walls built by such trees are strong enough. It is worth noting that Henan County is located in the north, and most of the trees in the forests are pine trees. When the newly cut pine trees are slightly baked, many light yellow oils will overflow, namely resin, which is very sticky and easy to burn, and will be damaged by fire.

Moreover, once the resin burns, it will last long and stubbornly and cannot be extinguished easily. In addition, black lumps are flammable and explosive things, so the fence walls quickly spread, burning more and more vigorously, and the fire becomes bigger and bigger, forcing the defenders on the wall to stay in place at all. They have to retreat in a panic, or jump off the wall directly, or move along the wall pallet to the distance to avoid the fire.

When the Xiliang cavalry under the city approached the wall, the defenders on the wall put their bows on their strings, trying to shoot the ignorant Xiliang soldiers. However, with the first black bumps exploding, the loud noise that seemed to exploded thunder instantly overwhelmed the shouts of killing in the wilderness, resounded throughout the night sky, and spread throughout the camp. So the defenders on the wall were the first to be hit, panicked by the loud noise, and suddenly became disorganized and lost their composure. More than half of the defenders' archers forgot to shoot arrows. Only a small number of calm-minded soldiers released the arrows in their hands, but they lost their correctness. They were not strong enough to effectively kill the Xiliang cavalry, which was useless.

"Bang bang bang! Boom——" Just as the defenders on both sides of the gate were panicked, hundreds of black bumps roared, extending from the east wall to the west, and exploded continuously on the fence that was 1,500 meters long. In an instant, the explosions were connected, and the loud bangs enveloped the front camp of Cao's army and spread rapidly, affecting the entire camp. A narrow and long fire dragon formed under the dark night sky, and the fire light soared into the sky, followed by one sound after another.

The explosion roared in the sky, and thick smoke soared into the sky. Soon, the entire Cao army camp was boiling, with war horses roaring and neighing, the sound of horse hooves roaring, screams, running and screams intertwined, causing the Xiliang army, far away from the camp to clearly hear the sound of collision and trampling from the camp, and the panic scattered figures under the fire. It was extremely noisy, not inferior to the explosion of the black lump, and even more so.

However, the huge explosion like thunder continued. Unlike before, this explosion was no longer limited to the fence and wall, but directly exploded inside the camp. Amid the thunderous explosion, thousands of war horses in Cao camp flew out of the camp. Tens of thousands of Cao army soldiers rushed out of the camp bare shirtless, and even ran out naked. However, they were not the Xiliang Iron Cavalry who broke through the gate, but the soldiers who were frightened like them, and the war horses that ran away from the reins when frightened.

In the chaos, the wind lights in the camp tent fell, and the soldiers who were wearing torches outside the camp were knocked away by war horses. The torches fell on the camp tent, so the camp tent was lit. Seeing that the camp tent caught fire, no one extinguished the flames at the first time, they all turned a blind eye and fled to their lives. In this way, a camp tent caught fire, and when the fire was slightly larger, it immediately ignited the camp next to it; this cycle continued, hundreds of camp tents in the front camp turned into a sea of ​​fire in an instant.

The wind roared with the fire, and the fire roared with the power of the wind; in an instant, the wind and fire moved side by side, quickly swallowing the tents, and swallowing Cao's army that had no time to rush out of the tent. The fire was surging, and thick smoke rolled over the entire camp.

The camp caught fire, the war horses were frightened, and more than 100,000 Cao's soldiers were in a state of excitement, and Cao's army was in chaos.
