The moon was fine tonight, and the silver moonlight shone down on the earth. Wuwei is already on the edge of the desert with sparse vegetation, standing on the Wuwei city wall, more than ten miles below can be seen at a glance.

This kind of weather is good for the defenders, but bad news for the sneak attackers. Cao Bianjiao looked at a bright and clean land and nodded with satisfaction. With more than ten miles of visibility, he can calmly deal with the surprise attack of the Mongols.

At present, the only thing that can pose a threat to the Wuwei city wall is heavy rocket artillery. But since the battle of Eagle Beak Mountain, the Mongols haven't seen how the Mongols have used it.

It is estimated that the launcher was killed a lot by the airship, and if this thing is still on the surface at dawn, it will be a fixed target for the airship. If it misses, the bombardier of the airship can go home and pick up the child.

The Mongols' fragile logistical supply lines were also unable to replenish heavy rockets. That thing weighed more than 300 catties in one shot, and the oxcart pulled by two bulls could only pull two rounds. Two oxen ran thousands of miles from the Ili River valley to Yinchuan, and if they didn't get it right, they would be bombed by airships. From time to time, there was harassment by the cavalry of the Ming army, and it was quite difficult to transport.

The launcher is gone, and it is too difficult to transport shells. The Mongols simply don't play with this thing, and now they don't even have a lot of small-caliber artillery like mortars in their hands. If you want to attack the fortification, you can only run under the city wall with explosives bags.

With such high visibility, I want to run under the city walls. A rifle with a high head will teach them how to behave.

A clever general would not have chosen such weather conditions for a sneak attack, but the Mongols could not help it. Time is of the essence for them, and if it snows in a few days, their supplies will be completely cut off. And attacking Wuwei will be even more difficult.

Just as Cao Wenzhao was looking down, Dolgon and Geldan in the distance were also looking at Wuwei City. They also knew that such weather was not good for the attacking troops, but the desert experience was far more abundant than that of the Han people who came from afar.

"Are you sure there will be tonight?" Dolgon grew up in Liaodong, and he didn't know much about the Gobi Desert.

"Absolutely, Agrand has never been wrong in predicting the weather. Sandstorms don't usually happen in winter, but this winter there was almost no snow and the ground was very dry. Today is another strong northwest wind, and as long as it blows, it will kill them in a sandstorm. Gerdan looked up at the silver platter-like moon, and on the edge of the moon there was a large circle of wind.

This is a sign of a strong wind, and Geldan sincerely prays. Sandstorms, which are rare in winter, will blow tonight.

"If there were no sandstorms, we would have to burn that poplar forest. But the smoke from the poplar forest is unlikely to cover the entire sky. At most, that is, to attract the attention of the Ming army. If you want to succeed in a raid, you have to rely on luck. Dolgon reluctantly pointed to the poplar forest in the distance, this was a backup plan that did not wait for the sandstorm, there was no way. The effect is not the same as that of a sandstorm.

"Don't worry, look at the big wind circle on the side of the moon, it's a sign of a strong wind. By midnight at the latest, a strong wind is bound to blow. There is no snow this winter, and as long as the wind blows, there will be sandstorms. It is more violent than the sandstorm in autumn. "Gerdan is very determined.

"I hope so!" Dolgon had seen autumn sandstorms, and the yellow sand that covered the sun all day made it feel like the end of the world. I don't want to experience that scene for the second time in my life. With palpitations, he touched a handful of cloth towels around his waist, and between the two thick cloth towels was the muslin cloth that the Han people had snatched. There is a rope on one side that can be hung from the ear.

Perhaps to verify the words of Goldan's weather forecaster, Dolgon's hand had not yet had time to be withdrawn. There was a strong gust of wind, and Dorgon felt like he was about to suffocate.

"Whoa!" There was a wolf-like cheer from the side.

Under the bright moonlight, Cao Bianjiao's mood was quite good. It doesn't seem like much of a little wind, after all, it's winter, and it's not surprising that it's windy.

But when he saw the black smoke sweeping over, his face turned white all of a sudden.

Sandstorms in winter are very rare, but today I just happened to fucking me. After being in the northwest for a long time, Cao Bianjiao knew the severity of the sandstorm. The violent sand was blown by the more violent winds, and the person was exposed to the outside for a while, and the whole person seemed to be dug out of the soil.

"Put your mask on!" Cao Bianjiao's shout changed tone.

The Liao army had a tradition of wearing masks in winter in eastern Liaodong, which was initially to prevent soldiers from infecting each other with colds. Later, I found out that this thing also has a good warmth effect. So when the Liao army arrived in autumn, masks were generally distributed. Hopefully, tonight, these bastards will all be wearing masks.

Far on the horizon, a black wall of earth was pushed flat. Cao Wenzhao knew that the Mongols would not let go of this opportunity. Perhaps, tonight is the opportunity they have been waiting for.

When the Black Storm came, everyone felt suffocated. The soldiers who were hiding in the tower without masks covered their mouths and noses with things. But the fine smoke and dust still don't know where to get into the nose. The mouth was full of earthy smell, and the sound of sneezing and coughing in the castle tower was loud.

The people wearing masks outside weren't much better, except for a few guys with goggles, and the rest couldn't even keep their eyes open. The soldiers huddled inside the tower, the sand stirred by the strong wind, and the bullets that hit the walls outside made a "crackling" sound.

Even with goggles, I can't see things in the distance clearly. Even when you look down at the top of the city, you can't see what is going on below.

The Mongols, who had a tailwind, attacked at the first opportunity. A dozen fast horses were as fast as lightning, and the knights on the horses were wildly brandishing their whips and smoking their beloved war horses like treasures. They didn't have any weapons on them, not even scimitars. On everyone's back, fifty pounds of explosives were carried. Their faces were covered with several layers of cloth scarves, and they had only a pair of wolf-like eyes, staring at the blurred city wall in the distance.

A rope was tied between the war horse and the war horse, for fear that they would run away. More than a dozen figures rushed towards the city wall. The Knights knew they only had this one chance. The horses under the crotch do not live long, because they inhale too much dust, and they will die quite painfully.

There is a shortage of water in the northwest, so Wuwei does not have any moat. More than a dozen Mongolian warriors rushed to the bottom of the city wall, quickly jumped off their horses and pulled the rope together. When their hands touched the city wall in the dark, everyone's hearts bloomed. The sandstorm helped them get through the toughest of places, just dig a big hole in the wall, put all the explosives bags in and set it on fire, and it was all done.

The iron pickaxe slammed into the wall, and soon a small crater the size of a fist and three inches deep appeared on the wall. One guy pulled a cylindrical object out of his waist, slipped it into a hole in the wall, and pulled the fuse. The fuse began to burn with the flames of "呲" and "呲", and everyone ran backwards and then lay on the ground.

"Boom!" Inside the sandstorm, the sound of the explosion was unusually dull. But Cao Bianjiao still heard: "Where is the explosion." Cao Bianjiao asked left and right in horror, but no one answered him. The wind of the sandstorm with all kinds of strange howls raged in the sky above Wuwei City, sounding as if it was going to blow Wuwei City away.

The Mongols quickly checked the explosion point, and the effect was very good. What had just been a hole the size of a fist had now become a hole that could be slipped into by a cat. Untied the explosive bag he was carrying, and stuffed it into the innermost without hesitation. After pulling the fuse, he immediately rushed out like a rabbit and hid under the city wall.

"Boom!" The sound of the explosion was louder, and this time Cao Bianjiao also heard it clearly, the sound came from Beicheng, the direction he was most worried about.

"Let all the people in the North City get out." Cao Bianjiao shouted anxiously, but when the sandstorm was raging, no one could hear his roar.

The veterans on the walls of the northern city clearly felt the shaking under their feet. Experienced old guys, quickly made a judgment. The men wearing goggles searched along the city walls, and the remaining veterans dragged the recruits and ran down the road to the city as if they were dying.

Once again, the Mongol soldier burrowed into the hole, this time with his head down. Desperately pulling the rope a few times, the Mongols who were hiding in the distance immediately ran over. There was no verbal exchange, and everyone untied the explosives bags from their backs and stuffed them into the holes one after the other. When all the explosives were stuffed into the hole, a Mongol soldier began to connect the gunpowder twists.

As soon as the fire pipe was pulled, the whole person ran as if he was dead. If you run slowly, you risk being shocked to death, after all, there are hundreds of pounds of explosives here.

He had just run a few steps when an explosion was heard behind him. Grenades began to be thrown indiscriminately on the walls, and this guy was unlucky, a grenade was blowing up behind him. Shrapnel the size of a fingernail was inserted into his waist, and the Mongolian soldier fell to the ground with a "poof". has a strong desire to survive, so he moves his body on the ground like a maggot.

"Boom!" There was a sound of the sky and the earth cracking, and under the sound of a huge explosion, the entire Wuwei City seemed to tremble. Broken bricks and tiles flew everywhere on the city wall, and the smoke was blown away by the sandstorm in an instant.

The Mongols sent more than one team, so there was more than one explosion. Grenades were constantly dropped from the city walls, although a blind cat could kill a few Mongols when it touched a dead mouse. But the explosions still came into Cao Bianjiao's ears one after another.

"Boom!" "Boom!"

"Boom!" ……！

Four gaps were blown in the northern wall, and three in the west. When the sandstorm slowly weakened, Dolgon and Gerdan saw the Wuwei city wall like an old lady with lost teeth.

"There are countless riches, women and food in Wuwei City, and you don't want to starve to death. Rush! Geldan drew his saber and swung forward with force, and countless Mongol cavalry rushed forward like a tidal wave.

The sandstorm had not yet subsided, but the Mongol soldiers rushed up like another earthen wall.

"Mortars are prepared, and the calculators calculate the location of the gap." Cao Bianjiao was so anxious that he shouted loudly, and the calculation soldier standing on the tower began to nervously calculate the position of the gap. The gunner on the ground, with a shell in his hand, waited for the school gun to fire.

The Mongols rushed very closely, and the first shots were fired at the wall, and then the shots rang out like firecrackers.

Many of the Mongols fell off their horses, while others galloped back with rifles in their hands.

The Liao soldiers are all veterans, and their marksmanship is far from being comparable to those guys in the garrison. The muzzle of the gun was pressed in advance, and the horse was not beaten. Although it doesn't snow in winter, the ground is cold and hard. Falling off a galloping warhorse, the taste of "hey" "hey" will be seriously injured if you don't die.

Horses have bigger goals than people, and hitting horses is more accurate than hitting people. The scorching bullets continued to burrow into the horse's body, and blood burst out along the ruptured wounds. Even a muscular war horse could not withstand the fire of a large-caliber rifle.

One by one, the horses fell to the ground, and the knights on the horses also had zero contact with Mother Earth.

The Mongol cavalry fell so badly that the ground was as cold as stones in the winter. And there are all kinds of rough little stones, which only the most athletic people can escape, but they will also end up disfigured.

Most guys don't have such agility, some have broken tendons, and some have broken their necks. What's worse is that he broke his arm and leg and was wailing loudly. The head was kicked by a galloping war horse, and the hooves of the horse, the size of the bowl, could kick people unconscious. The horse's powerful hind legs step on the chest, and the entire sternum will break in unison.

The stubble of bones, with yellow marrow, can even pierce out of the inside of the leather robe. The whole person is like a soup bag with broken skin, and the filling is constantly flowing out of the wound.

However, the Mongols did not care about the casualties at all, and the knights still tried their best to whip the buttocks of the horses. They know that this section of the area is the most dangerous place. Only passing quickly is the best way to save your life. Moreover, the faster the horse, the less likely it is to be hit.

Someone had already rushed to the gap, and the monkey-anxious recruits in the Liao army leaned out half of their bodies and shot downward. As a result, without exception, they were pierced by the bullets fired from below, and the Mongols seemed to be born with an extraordinary talent for shooting. Their marksmanship is no worse than that of the veterans of the Liao army.

The recruits were shot down by the Mongols like birds, and no one on the city walls dared to lean out and shoot. Instead, there were smoking grenades, and clouds of exploding smoke rose from under the city walls.

The Mongols, who were shooting at the city walls with their guns in hand, were hit by numerous tiny shrapnel. Some were killed as a direct blowing, while many more were injured. There are even guys whose eyes were hit by shrapnel, rolling on the ground with their hands covered and screaming.

More and more Mongols rushed to the city, and they threw off their stirrups and dismounted their horses. Holding a rifle "whoop" and "whooping", he climbed onto the rubble pile, and rushed into Wuwei City lifelessly.

In just a few minutes, more than 200 people burst in. All of a sudden, the situation became tense!
