Since it was night, the view of the hot air balloon was greatly affected, and the pilots could not observe the movement of the enemy on the ground, not to mention the thick smoke floating into the sky, and the pilots on the hot air balloon were also affected. Therefore, vigilance is important, and soldiers have to risk tears from the smoke to do it.

The Xianbei army was now gathering behind the line of fire, like a hungry wolf that saw its prey, drooling, with green light in its eyes, staring at its prey, ready to pounce on it and bite its prey.

Budugen and the leaders rode and stood at the front of the group, nervously waiting for the moment to come. Everyone including Bu Dugen was very excited, they had been pressed and beaten by the Han army, and it could even be said that they were unilaterally slaughtered, but they had no ability to resist at all, and now they were finally able to be ashamed.

At last, we can watch these hateful Han people die in the flames, and everyone talks happily, what could be happier than watching the enemy step by step towards death?

Just as the Xianbei people watched with great expectation as the raging line of fire slowly advanced towards the Han camp, they were surprised to find that the fire began to slowly weaken about eighty paces away from the camp, and finally stopped its advance twenty paces away from the camp and was completely extinguished.

With the extinguishing of the line of fire, the hearts of the Xianbei people were also half cold, they couldn't figure out what was going on, how could the fire stop in the grassland where there was nothing but grass? And even with the revelation given by the Immortal Heaven, how could the fire be extinguished at the last moment? Could it be that Changsheng naively abandoned the Xianbei people?

The Xianbei people did not understand the reason for the extinguishing of the fire, but the people of the 1st Division knew it well. The reason is simple, because there is a wide fire barrier here. This wide fire barrier was partly dug out by the 1st Division, and partly generated by the daytime battles.

During the day, tens of thousands of cavalry rode their horses on this land, and the grass on the ground had long been trampled into the dirt. And because tens of thousands of horses died, there were not 10,000 but 8,000 in the northwest direction, and the blood of people and horses flowed all over the place, especially the horses, which were large in size and large in blood capacity, and the blood shed was also very large.

A large amount of human and horse blood made the land wet~moist and even muddy. When the fire burned to this area, it naturally weakened or even extinguished.

Although the great shaman of Xianbei knew how to observe the celestial phenomena, could make weather forecasts to a certain extent, and also knew some tactics in the art of war, and came up with the vicious strategy of fire attack, he may not have seen the battlefield in the daytime, and he could not imagine the situation of thousands of people and horses dying in a small area under the intensive attack of firearms, so he did not expect that such a battlefield environment would have such a big negative impact on his fire attack plan.

Most of the fire was blocked by this fireproof barrier of flesh and blood, and only the sporadic fires stubbornly crossed this wide area of dozens of meters, and came to a place twenty paces away from the camp of the First Division, which was artificially dug by the soldiers of the First Division, and there was no grass left in this place, even if there were some small sparks that could burn here, they were finally completely extinguished.

In the past, when Liu Hou led his troops to fight with the Wei army in Jingzhou, he was almost burned to death by the other party once, and that time it was a poisonous plan that Sima Yi came up with. Since that time, the Hong army has attached great importance to the fire prevention problem of the camp, and whenever they set up camp, they always have to dig a fire isolation zone around the camp, which has been written into the regulations, and it is military common sense that every officer understands.

The soil on the steppe was relatively loose and there was no tall vegetation, so it was not difficult for the 1st Division, which was equipped with a sapper shovel as standard, to dig a fire barrier. The 1st Division dug a fire barrier before camping, but I didn't expect it to come in handy now.

"This, this, what the hell is going on?" Budugen looked at the fire that was gradually extinguishing, his face was horrified, and his hopeful revenge plan disappeared like this? He wanted to urge the horse to rush forward, and led the army to rush into the camp of the Han people and kill them all.

However, he was really afraid of the Han army's hidden weapons that could make loud noises, and reason told him that if he did that, there would be no second end except for countless holes in his body.

He clenched the reins in his hand, clenched his fists, and his teeth rattled in his mouth, but no matter how angry he was, he did not dare to rush over. Slowly, the fire in front of him was completely extinguished, and the burned earth gradually cooled down, and now there was no problem for people and horses to step on it, but Budugen still did not gather enough courage to order the army to rush over.

Finally, reason prevailed over impulse, and Budugen turned his horse's head and ran back without a sound, and the army slowly turned and withdrew with him.

The first division was smoked in the middle of the night, and everyone became like coming out of the gossip furnace of Taishang Laojun ~ into golden eyes, fortunately they could take turns to rest, and those who rested put wet towels on their eyes, closed their eyes and recuperated, which supported them until the fire was extinguished, otherwise I don't know what evil consequences would be caused.

In addition to the eyes, many people's chest and lungs are also very uncomfortable, although there are wet towels, but after all, it is not a professional smoke-proof equipment, and there are still many people who inhale some smoke and cause lung discomfort.

Although most people's lungs are fine, because they cover their mouth and nose with a wet towel, the resistance increases greatly when breathing, so they can only exhale and inhale extra hard, and it is no problem to do this in a short time, but this fire is very large and lasts for a long time, which causes excessive fatigue and soreness in everyone's respiratory muscles.

However, these discomforts mentioned above are minor problems, and they don't even need to be treated, as long as you rest for a few days to recover as before. Zhang Bao understood everyone's hard work at night, and ordered to rest for a morning the next day, and then march out of the camp after lunch.

However, in this morning, in addition to the sentries, there were two kinds of people who had no rest, one was the doctor who accompanied the army, and they were busy continuing to treat the wounded Xianbei war horses; There is also a kind of people who are the gang leaders, in addition to cooking for the army, they also have to take the time to continue to move some dead Xianbei war horses back to make jerky.

After eating lunch, the army walked for an afternoon, and it was less than a day's journey from Danhan Mountain, and according to the original plan, it was possible to reach Danhan Mountain today, but because of a delay of one morning, this goal was not achieved.

This is also something that can't be helped, in that situation last night, even if Zhang Bao forcibly asked the soldiers to hurry and arrive at Danhan Mountain on time, the combat effectiveness of the soldiers would definitely be greatly affected, and they would not be able to attack the enemy immediately, and the final result would be more than worth the loss.

On this night, the First Division was in full array, guarding against the Xianbei people from continuing to sneak attack, but in the end, in the vast grassland, not a single Xianbei figure was seen. I don't know if Budugen has been frightened and led the troops to escape.
