A pair of Xianbei cavalry armed with torches were galloping towards this side, and when they learned of the information of the invasion of foreign enemies, they quickly armed themselves and killed the enemy as fast as possible. As the first echelon of attack, they were planning to deal a heavy blow to the incoming enemy in order to defend their Xianbei homeland.

In the dim light, they had already seen those enemies dressed in green in the distance, they began to get excited, their breathing began to be short, their blood began to boil, they gradually increased the speed of their horses, drew ~ the full moon scimitar, raised it high, and as soon as they crashed into the enemy formation, they began to slash and kill the enemy.

Just when these Xianbei cavalry were about to come into contact with the enemy's line, they suddenly noticed a wall of fire appear in front of them. This wall of fire appeared extremely quickly, from nothing to a small flame to a wall of fire more than a person high, in just a few breaths.

The speed of such a fast fire is completely beyond the common sense of Xianbei people, but anything that is beyond the scope of common sense is easily reminiscent of some supernatural powers, and the more ignorant people are, the more they will think in that direction. Therefore, many Xianbei people were horrified in their hearts, afraid that there was something supernatural waiting for them in front of them. The unprepared and suddenly frightened Xianbei cavalry were frightened, and they reined in their horses and slowed down, and many people were panicked, unable to grasp the reins in their hands and fell off their horses, and the result could only turn into meat puree.

Many of the horses were raised by the reins, and the legs of the horses shoveled deep gullies in the grass as a result of the slowdown. Countless horses shoveled past, and the grass seemed to be ploughed over, and the entire turf was turned over, so that the speed of the fire slowed down significantly when it spread to this area, and some of the severely damaged places even simply extinguished the fire, which made the soldiers of the 1st Brigade who were responsible for the ignition of this area depressed, so they had to cross this area and re-ignite the fire after the Xianbei cavalry retreated.

Back at the scene, it was said that the Xianbei cavalry in front braked one after another, and the cavalry behind the car that couldn't stop the car crashed into the cavalry in front, and the people and horses rolled into a mess. There were also cavalrymen who were close to the wall of fire, and they could not stop even if they braked with all their might, and in the end, they rushed over the wall of fire with men and horses.

The soldiers of the 1st Brigade hurriedly removed the weapons on their backs, and quickly stabbed or chopped the ground to quickly kill the Xianbei cavalry who were still rolling in the ground. Fortunately, there were not many Xianbei cavalry who rushed through the wall of fire, otherwise, the consequences would be unpredictable. However, even now the Xianbei cavalry has come to its senses, it is too late, in the beginning, the wall of fire was still very thin, and the cavalry could actually rush through it with speed.

However, in just a moment, the wall of fire quickly became taller and thicker, and quickly spread southward, and it was impossible for the Xianbei cavalry to rush through the fire range even at full speed. Those Xianbei cavalrymen who fell to the ground in front of the wall of fire were smashed to pieces, and they couldn't get up for a while, and watched a wall of fire rushing towards them.

Those who are less injured grit their teeth struggle to get up and escape, and those who are more seriously injured can't get up, so they can only obediently turn into roast pigs. The Xianbei cavalry, who did not fall off their horses, quickly came to their senses, turned their horses' heads one after another, and slapped their horses and ran lifelessly along the way they came.

They had to hurry back to ventilate and let the people flee quickly, they had lived on the grassland since they were children, they had not seen the fires on the grassland, they knew that this was a terrible thing, and they could not escape if they were a little slower.

But there was no need for them to report the news, the people in the Xianbei camp had already seen it the moment the fire dragon was lit. After all, it is wartime, and there are special people who keep an eye on the movements here, this fire dragon stretches for miles, and the sky-high fire is especially conspicuous in the dark night.

The Xianbei camp suddenly rioted, and this riot was a real riot, much more serious than the riot caused by the discovery of an enemy attack just now. When the Xianbei people found out that the enemy was attacking just now, only those soldiers were woken up, but now it was different, and the people in the entire camp, whether men, women, old and young, whether civilians or nobles, were all called up.

This time it is not to fight the enemy, but to flee for your life, water and fire are ruthless, no one has the courage to fight in the face of such a monstrous fire, the only thing to do is to escape, how far to escape.

The reason why the Second Division started today was that it had to find people in the field of weather forecasting to see the celestial phenomena and choose this good day. Unlike the Xianbei people who rely on shamans to predict the weather, Liu Hou set up a meteorological research institute in the "Dahan Longteng College" and recruited some specialized talents to conduct meteorological research.

Due to military needs, all units have these meteorological personnel to follow, just to make weather forecasts in important military operations. Weather is important in warfare and can often make the difference between victory and defeat. For example, this operation is highly dependent on the weather, and whether the operation can succeed can be said to depend on whether God gives face.

If it rains or snows, the operation will definitely fail, even if there is no rain or snow, the wind is not in the right direction, if the south wind blows, the fire will turn upside down and burn your own people, not only will the operation fail, but your own troops will also be in danger.

Even if there is no wind or the wind speed is too slow, in that case, the fire will spread too slowly and not pose a threat to the Xianbei people. Therefore, the best weather conditions for this "Tianhuo" operation are: there is no rain or snow, and the north wind blows, and the wind strength must reach at least four or five or more.

Fortunately, this time God was more powerful than Changshengtian, and successfully cooperated with the actions of the Second Division, or the meteorologists accompanying the Second Division, and successfully predicted a good weather. On this day, a cold snap came down from the north, and a strong northerly wind blew from the grassland.

The wind speed initially reached level 6, and not long after the first brigade ignited, the wind speed gradually increased to level 7, and the long grass on the ground rustled like the sound of waves. Since the sky had just begun to change, it was only a precursor to the cold snap, and although the sky was already cloudy, there was no rain or snow.

The timing of this fire attack turned out to be unprecedentedly good, if it was a few days earlier, there would not be such a strong north wind, and if it was a few days later, the snow might have to fall, and then the opportunity for fire attack would be completely lost. To be able to choose such a good day, although it is supported by the professional knowledge of the meteorologist, it has to be said that there is a certain element of luck, so it is reasonable to attribute it to God.

It was a good day for the 2nd Division, but it was a tragic day for the Xianbei people. The Xianbei people who woke up, in the shouts of the leaders of the clan, hurriedly packed up the valuable things at home, harnessed the horses and ox carts as fast as possible, and then rushed south to flee for their lives.

Unlike the Han people who fled to clean up the gold and silver in their homes, the Xianbei people fled and packed up valuable things at home, but they were not soft gold and silver. Gold, silver, fine and soft these things are not very useful in the grasslands, and the hard currency here is livestock, population.

The so-called hard currency is something that can be used as money in transactions, and here, livestock can be bought and sold, as can people. The Xianbei people often traded in the form of barter. And livestock can be exchanged for almost anything.
