Sigh!

The sudden scream of the war horse broke the silence under the night sky, which was not only a warning to Cao Jun, but also exposed the whereabouts of the sneak attackers hidden in the night.

"Break through the enemy camp and kill!" In the neighing of the war horse, he saw a silver-white figure leaping forward, and the cold and shining spear pointed directly at the Cao army camp in front of him.

"Da Da Da -- Kill!" The sound of horses' hooves rumbled, and the shouts of killing resounded in the night sky.

With the order of the main general, the 10,000-strong cavalry team that was originally hidden no longer had any scruples, and one by one they broke off the reins, screaming and rushing straight to the gate of the Cao army's camp.

At the same time as they showed their figures, the Cao army patrols roaming the Yuanmen Wilderness quickly gathered from all directions, trying to intercept and encircle these Xiliang Iron Cavalry who had suddenly killed.

Suddenly, accompanied by the "boom" of firelight, Cao Jun, who was patrolling the night, lit the torches and illuminated the wilderness. Immediately, a rain of arrows swept through the night sky, and the two armies of the prancing horses swooping met head-on, and the battle broke out at this moment. In the flickering firelight, but a silver figure took the lead, brazenly slaughtering into the Cao army that tried to intercept it, followed by 10,000 cavalrymen leaping and galloping, and every cluster of arrows was aimed at the firelight.

"Puff, puff, puff!" The sound of the sharp weapon breaking suddenly rose up, followed by a terrible scream. The bright light of the torches exposed the location of the Cao army's soldiers, and invisibly provided a target for the Xiliang Iron Cavalry to shoot accurately at night, giving the Cao soldiers a head-on attack at the first time when the two sides encountered, and the arrows were not missed. A large area of shooting kills, so that the Cao army scouts who were blocking the way of the charge were shot and fell off their horses one after another. Clearing the obstacles to the charge provided the army with valuable space to storm the gate.

Obvious. This Xiliang Iron Cavalry who went out of the city late at night to rob the camp was a 10,000-strong cavalry team in the Wushuang Iron Cavalry Camp under Zhao Yun's tent. The Wushuang Iron Cavalry Battalion was fully staffed with 33,000 men, with 30,000 cavalry troops, of which 1,000 were directly subordinate guards under the main general and deputy generals, and the other 2,000 were scouts and sentinels.

In the offensive and defensive battles during the day, most of the 5,000 soldiers defending the city under Zhao Yun's account suffered casualties, and now there are less than 2,000 county soldiers who can still hold on to the city. At the same time, the 10,000 cavalry who reinforced the city also suffered heavy casualties, and the cavalry was changed to an infantry army to defend the city, and its combat effectiveness was sharply reduced. Of the 10,000 cavalry, only about 3,000 survived. Therefore, after defending the city one day, Zhao Yun's soldiers and horses lost more than 10,000 foot horses, and suffered heavy losses.

Seeing this, Zhao Yun knew that Kaifeng City would not be able to hold it. In three days at most, nearly 40,000 soldiers in the city will be annihilated, and the city will be destroyed and killed. Knowing that you can't do it is not a wise thing to do. It was Zhao Yun's decisive decision to abandon the city and retreat. However, he, Zhao Yun, was by no means a person who could not fight back, so he decided to give Cao Jun a color before the army withdrew from Kaifeng City - a night raid and robbery camp.

It is called the robbery camp, in fact, Zhao Yun never thought of breaking through the Cao army camp in one fell swoop, after all, there are more than 100,000 troops stationed in the camp. The 10,000 iron cavalry led by him alone could not shake the Cao army, let alone succeed in robbing the camp. So he retreated to the next best thing, and the purpose of the trip was simple. Just to create chaos for Cao Jun. As long as he can make hundreds of thousands of Cao soldiers chaotic, there is no need for him to lead the army to kill. The soldiers of the Cao army in the large camp will trample on each other and suffer huge losses. If only it could. Zhao Yun led the army to attack late at night The purpose was achieved, and then took advantage of the civil strife of the Cao army to lead the army to withdraw from Kaifeng City and retreat to Zhongmu, so that he could retreat with his whole body.

In the sound of the "Qiang Qiang" weapon collision, Zhao Yun took the lead, sat under the BMW Snow Lion, and held the divine soldier gentian gun in his hand. Behind him, 10,000 iron cavalry formed a sharp arrow charging formation, and he was the bladed arrow, followed closely behind like an arm and finger, approaching the Cao army camp at a speed visible to the naked eye.

One hundred and fifty steps closer to the camp, without waiting for the guards of Yuanmen to fire arrows, I saw Zhao Yun standing upright, holding up the gentian gun, and shouting: "The two wings are roundabout, throw fire and thunder, scatter!" ”

The 10,000 iron horsemen who followed behind him dispersed when they heard the sound, and scattered in front of the Yuanmen of the Cao army's camp, avoiding the archers at the main gate and the tower of the Yuanmen City, and the arrow array instantly evolved into a "one" shaped goose-shaped array, and rushed straight to the walls on both sides of the Yuanmen. At the same time as the formation dispersed, these cavalrymen took out black bumps the size of melons from the black leather bags on both sides of their horses, and in groups of two, the cavalry with black bumps charged on horseback, and the other person followed closely behind, charging while putting on the bow and winding. At the moment when the cavalry in front struggled to throw the black bump, the cavalry behind lit the rocket and fired the arrow in the direction of the black pimple, and the rocket came from behind, hitting the three-foot wall stake before the black pimple, and then the black pimple hit the stake fence wall overflowing with sparks.

"Boom!" The black bump that hit the wooden stake exploded when it encountered fire, and there was a loud "bang", which caused the wooden fence wall to shake violently, causing the defenders standing on the wall to have their ears flutter and lose their minds, and even two defenders were so frightened by the huge explosion that their legs and feet were weak, and their bodies were crooked, and they fell down from the wall, and their brains were splashed, and they died on the spot. The foundation outside the wall is very strong, and it is full of rocks or traps, which were set up to prevent the enemy from robbing the camp, but I don't think that this time it was used on Cao Jun himself, as long as he fell from the wall, he would definitely die, and no one was spared.

On the other hand, the cavalry who threw the black pimples did not approach the wall, but rode their horses and rushed in a roundabout way, throwing all the black bumps in the black leather bags in succession. After the first black pimple exploded, the black pimple thrown out later did not need to be ignited, because the fence wall was already burning, and the wind was blowing at night, and the flames flickered. So as long as the second black bump smashed not far from the flames, it could explode immediately, and the effect was better than the first, at least loud enough, like a thunderbolt, and the defenders on the wall were dizzy, and Venus appeared in front of them. In this case, the soldiers of the defenders who were a little less psychologically frightened would be so frightened that they would sit on the wall pallet and dare not show their heads, or they would fall down and fall to pieces.

In order to ensure that the walls will not be deformed and stronger, the wooden stakes used to build the walls need to be slightly baked to remove the water, so that the walls built by the trees are strong enough. It is worth noting that Henan County is located in the north, and most of the trees in the mountains and forests are pines, and the newly cut pine trees will overflow a lot of pale yellow oil, that is, resin, which is very viscous and flammable.

Moreover, once the resin burns, it is long-lasting and stubborn, and it cannot be extinguished. In addition, the black bump was originally flammable and explosive, so the fence wall was ignited and spread rapidly, burning more and more, and the fire became bigger and bigger, forcing the defenders on the wall to be unable to hold on to their positions at all, and had to retreat in a panic, or jump off the wall directly, or move along the wall trays to a distance to avoid the fire.

When the Xiliang cavalry under the city approached the wall, the defenders on the wall set up their bows and tried to shoot these Xiliang soldiers who did not know whether they were alive or dead. However, as the first black bump exploded, the loud sound like thunder instantly overshadowed the shouts of killing in the wilderness, resounding through the night sky and spreading throughout the camp. So the defenders on the wall bore the brunt of the attack, frightened by this huge sound and panicked, suddenly confused, out of proportion, more than half of the defenders archers forgot to release the arrows, only a small part of the calm sergeant put the arrows in their hands, but lost their heads, and the strength was not enough, and they could not effectively kill the Xiliang cavalry, which was useless.

"Bang bang bang! Boom -- "Just as the defenders on both sides of the gate were panicking, hundreds of black bumps roared in, extending from the east wall to the west, and exploded continuously on the 1,500-meter-long fence wall. Suddenly, the sound of explosions was continuous, and the loud roar enveloped the front camp of the Cao army, and quickly spread, affecting the entire camp. A long and narrow dragon of fire was formed under the dark night sky, and the flames soared into the sky, and then roared into the sky with one explosion after another, and the smoke soared into the sky. After a while, the entire Cao army camp was boiling, the war horses screamed and neighed, the horses' hooves rumbled and confused, and the screams, running sounds, and screams were intertwined, so that the Xiliang army far away from the camp could clearly hear the sound of collision and trampling from the camp, as well as the panicked figure under the firelight, which was extremely noisy, and it was not much better than the explosion of black bumps, and even more than that.

However, the loud explosion continued like a thunderbolt, and unlike before, this time the explosion was no longer confined to the fence wall, but exploded directly inside the camp. In the roaring explosion, thousands of war horses in Cao's camp screamed and scurried, and tens of thousands of Cao soldiers rushed out of the camp bare-chested, and even ran out bare-assed, but they were greeted not by the Xiliang Iron Cavalry who broke through the gate, but by the sergeants who were awakened as frightened as them, and the war horses that ran wild under the fright.

In the confusion, the wind lamps in the tent fell, and the sergeant with torches outside the tent was knocked up by his horses, and the torches fell on the tent, so the tent was set on fire. Seeing that the camp was on fire, no one put out the fire at the first time, they all turned a blind eye and fled for their lives. In this way, a tent caught fire, and when the fire was a little bigger, it immediately ignited the tent next to it; In this cycle, hundreds of tents in the front camp turned into a sea of fire in an instant.

The wind roars by the fire, and the fire roars and rages by the wind; In an instant, the wind and fire went hand in hand, quickly engulfing the camp tents, and also swallowing the Cao army who had no time to rush out of the camp. The fire was raging, and thick smoke billowed the entire camp.

The camp caught fire, the war horses were frightened, hundreds of thousands of Cao soldiers were boiling, and the Cao army was in chaos.
