———— the following text————

On the seventh day of October, Zhao Hongrun led his Su Wangjun to cross the Pigao Pass.

At this time, the fire on Yishan Mountain has been extinguished, and the once lush mountain forest has long been destroyed at this moment, so that from a distance, the two mountains of Yishan are scorched black, like ugly scars, which makes people feel very uncomfortable after seeing it.

I have to say that arson to the mountain is generally less good, because the so-called relying on the mountain to eat the mountain, relying on the water to eat the water, this time Zhao Hongrun burned down the entire Yishan, which means that in the next few years or even more than ten years, like Tang County, a county near the Yishan, or a mountain village located nearby, these local residents will not have a good time.

Therefore, Zhao Hongrun wondered if he would find a way to move the Han people living in this area to Linfen.

It is undeniable that this is a good idea, after all, Linfen is one of the few big cities in the western part of Hedong County, and it is not a problem to accommodate a few Korean people.

But the problem is that due to the ugly atrocities committed by the Northern First Army in this land during the previous Northern Xinjiang Campaign, the local Han people had an extremely bad impression of the Wei Army, and basically refused to move to Linfen to live.

Therefore, the only thing Zhao Hongrun can do is to reserve some food for the local Korean people to avoid starvation when the cold winter comes.

As he passed through the Leather Pass, Zhao Hongrun looked around at the pass, which should be the ruins of the pass to be exact—because the Wei army had used strategic weapons such as oil, a solid stone pass was burned to ruins.

The Pigao Pass, which was quite famous in Hedong County and Shangdang County, no longer existed.

In this regard, Zhao Hongrun sighed.

He didn't know whether it was right or wrong to frequently put oil on the battlefield as a strategic-grade weapon.

On the positive side, the power of oil is simply devastating, as strong as the skin prison pass, which is easy to defend and difficult to attack, and can only retreat in the face of the fire that uses oil as a combustion, because it is not at all human can contain it, and belongs to the category of natural disasters.

But on the other hand, oil is also very harmful.

First of all, it is very polluting, and if it is not burned completely, the oil film produced by the oil will erode the soil. Even if it is completely burned, the soil in this area will become salinized.

In the Henan City of Sanchuan County, that is, the tribal camp of the original Qianjiao tribe, Zhao Hongrun burned down this city with a huge amount of oil, which shocked the entire Sanchuan and made many Sanchuan tribes frightened and did not dare to be enemies of the Wei State.

But now, after two or three years, the land is still a scorched earth with no grass, and only a few tenacious weeds can be seen growing on that land occasionally, which does not look like a grassland area full of green meadows.

In addition to the impact on the environment, the frequent use of oil will also leak the existence of this black oil, and if the enemies of Wei know about the existence of this black water, so that it will be put into the battlefield against Wei in the future, Zhao Hongrun will feel worried.

You must know that oil does not exist only in Qiandi, at least when Zhao Hongrun attacked the Chu State, passing by a hill called "Burning Mountain" by the locals, he knew that the hill would burn violently in thunderstorms from time to time, and it was very likely that there was rich oil under the mountain.

In all fairness, Zhao Hongrun was not satisfied with the combination of catapults and oil barrel bombs.

Don't look at the power of oil when it burns, but in fact, think about it, you also know that the oil transported in wooden barrels can't actually create much fire at all, unless it is invested at any cost, as the Wei army did when it burned Henan City.

In Zhao Hongrun's view, this kind of fire caused by oil, it is more of a deterrent, so that the enemy army is afraid of this, as for the lethality, as long as the enemy generals figure out the nature of the oil, don't stupidly let the soldiers use water to extinguish the fire, but stay away as soon as possible, in fact, the fire caused by the ignition of the oil, it can only burn some defensive facilities at best, can not cause a large number of enemy casualties.

To put it bluntly, using oil to create a monstrous fire seems to be a natural disaster, but in fact, the efficiency of killing enemy troops is far less than that of Wei's crossbows and Lu's crossbows.

Imagine that in the "Battle of Hangu", the Wei army killed tens of thousands of Qin soldiers in just two hours with various strong crossbows, and this time it burned the leather prison pass with oil support, how many troops did the Han army lose?

Under the circumstance that the Han general Jin Huang ordered the withdrawal of troops in time, the personnel losses of the Korean army were negligible, and hundreds of people were killed.

Therefore, to regard this kind of weapon with a deterrent power greater than its actual power and various shortcomings as a strategic-level weapon, it can only be said that Zhao Hongrun has no choice.

"It seems that we still have to get a siege weapon to replace the combination of catapults and oil......

Thinking about this, Zhao Hongrun drove his mount and slowly passed through the ruins of this leather prison.

On the same day, the army of King Su was on the east side of Pigao Pass, the north side of Wangwu Mountain and the north side of Xihuze, on a spacious plain, preparing to build a camp here as a stronghold to attack Duanshi County.

But half a day later, when the Yan Ling army and the Shang Shui army had just arrived in the nearby forest, preparing to cut down trees to build a camp, the green crows who went to Duanshi County to investigate the news sent someone to send back the news, saying that Han General Jin Huang had withdrawn his troops from Duanshi County again, and continued to evacuate eastward with the people in the county.

After hearing the news, Zhao Hongrun frowned slightly.

He immediately took the guards and went to Duanshi County lightly.

Sure enough, as reported by the Green Crows, Duanshi County has become an empty city.

Even, the Han general Jin Huang did a very good job of evacuating during the evacuation, and set fire to many buildings such as granaries and houses in the city, making it clear that he did not intend to leave anything useful for the Wei army.

"This Jin Huang ......"

Looking at the burning Duanshi County, Zhao Hongrun couldn't help frowning.

At this time, Duan Pei, the leader of the Green Crows, came to Zhao Hongrun's side, hugged his fists and said: "Your Highness, in fact, the distance between the Han army and our army is not far, if you march in a hurry, you may be able to catch up with ......."

"It doesn't make sense." Zhao Hongrun shook his head.

What about catching up with Jin Huangjun?

At this time, the Jin army was retreating to the east with a large number of Korean people, if Zhao Hongrun sent troops to chase after him, would he be ambushed for the time being, in case the Jin Huang army abandoned those Han people when they found out that the Wei army was chasing in the rear, what should the Wei army do at that time?

Massacre of Han Min to vent his anger?

Or do you want to bring those Han people back and support them, and let the Wei army increase the burden of military food consumption in vain?

Therefore, it is better to let the other party retreat with those Han Min.

"Jin Huangjun...... In what direction was the retreat made? Zhao Hongrun asked.

"It's retreating in a northeasterly direction." Duan Pei replied.

Hearing this, Zong Wei Chang Wei Jiao took out a map from his arms.

This is a very special map, because it is clearly marked with "Shangdang" on this map, so as the name suggests, it is now controlled by South Korea Shangdang County, but in this map, there are many cities in Shangdang County, all of which belong to the Wei State, marked with the word "Wei".

It turned out that this map was the map of Shangdang when the Wei State had not lost the southern part of Shangdang County for decades, and it was made by Zhao Hongrun before rushing to the northern Xinjiang, sending Zongwei to the treasury of Zongfu to dig out the map of Shangdang and copy it against the leather map.

As for why he took this old map with him, there is only one reason: Zhao Hongrun hopes to use this map to inspire himself to defeat South Korea in this Northern Xinjiang Campaign and recover the land lost decades or even nearly a hundred years ago due to the defeat of his own army.

"The northeast of the Duan's family, that's the high wolf......"

Zong Wei Chang Wei Jiao pointed to the map and said in a deep voice.

Zhao Hongrun glanced at the long map, and his eyes were slightly in a trance.

"Duan's ...... High Wolf ......

He suddenly remembered a person, Sima An, the general of the Dangshan Army.

I remember that as early as the "Battle of Weichuan and Sanchuan", Zhao Hongrun had a night conversation with Sima An in order to obtain the full assistance of the Dangshan Army.

At that time, Sima An revealed his own origin, and it was then that Zhao Hongrun knew that the general of the Dangshan Army, who pursued the belief of "slaughtering all the people who are not of my race", was actually a descendant of the Sima clan, the general of Tianmen Pass.

At that time, outside the Tianmen belonging to the Wei State, there were several foreign tribes, such as the Qi people who called themselves 'Duan', the Hu people who called themselves 'Gao Wolf', and so on.

At that time, the Wei army guarding Tianmen Pass had a very harmonious relationship with these alien races, and even the Sima clan, the guard of Tianmen Pass, also mobilized soldiers to help these aliens build cities, so that they could avoid the invasion of cold winter wind and snow.

However, these aliens eventually betrayed the Wei state, and under the lure of Korea, they assisted the Korean army to capture the Tianmen Pass, resulting in the defeat of the Wei state in the "Shangdang Campaign", and the only remaining little land in the southern part of Shangdang County was also seized by the Koreans.

And the most fatal thing is that Wei lost Tianmen Pass and Mengmen Pass, which caused the war between the two countries to burn from Shangdang County to the narrow Hetao area in the middle of Hedong County.

It is no exaggeration to say that the losses suffered by Wei because of the betrayal of those alien races were no less than the fiasco of another Shangdang battle.

However, those alien races who betrayed the Wei State did not end much better, and they had already been driven by Korea to the barren land northwest of Shangdang County.

A day later, the Green Crows sent back the news again, saying that Jin Huang's army turned north in the area of Gao Wolf and withdrew into the "Hyun's" county.

As a result, there are now two routes for entering the army in front of Zhao Hongrun: Hyunshi County, or Tianmen Pass.

At this time, Zhao Hongrun had not yet received the news that "Zhao Yuanzuo, the king of Southern Liang, was defeated at Tianmen Pass", so after thinking about it, he decided to attack the Hyun clan.

After all, the Han general Jin Huang had just suffered a defeat at his hands, and the morale of the army under his command was low.

On the other hand, Tianmen Pass, although Zhao Hongrun wanted to help Zhao Yuanzuo, the king of Southern Liang, but as we all know, Tianmen Pass and Mengmen Pass, and even the two passes where South Korea deployed heavy troops in the Shangdang Army.

Especially Tianmen Pass, even the Northern Second Army under the command of Zhao Yuanzuo, the king of Southern Liang, has repeatedly failed to attack, could it be a soft persimmon?

Since you want to expand the results of the battle, of course, you have to choose the Han general Jin Huang of the Hyun clan to start.

However, after Zhao Hongrun led the army of King Su to arrive at Hyun, he received an urgent battle report from Linfen along Pijiao Pass, saying that Zhao Yuanzuo, the king of Southern Liang, was defeated at Tianmen Pass on the sixth day of October.

At the same time as receiving this news, Zhao Hongrun's face turned a little pale for a moment.

"Not good!"
