If we look at the blood relationship, Xu Changqing should undoubtedly help Wu Sangui at this time. After all, Wu Sanmei's relationship is here.

If Xu Changqing takes action at this time, even if he cannot defeat the migrant army, it will be unlikely to resolve the siege of Shanhaiguan.

But things can't be calculated like this.

Blood ties do not equal justice, nor does it equal truth!

Not to mention that Xu Changqing and the Wu family are not really related to blood, Wu Sanmei and Xu Changqing's son are almost the same.

At this level, in fact, whether Guanning or the refugee army are deformed products in a specific environment, no matter which side wins, they will not have any substantial help to the country and nation. They are just fat and ugly maggots.

Xu Changqing soon felt relieved.

As long as Shanhaiguan is still in the hands of the Han people, whether it is the Wu family or Li Zicheng, as long as they can guard it and are willing to fight with the Tartars, then Xu Changqing will support him!

Just as Xu Changqing was thinking, the battle situation became increasingly fierce on the top of Shanhaiguan City.

In the swaying fire, the elite soldiers of the refugee army became more and more brave as they fought, and they were about to gain a foothold in the main city. Although the Guanning Army tried hard to resist, at this time, neither morale nor ability could keep up.

"Brother, what should I do? What should I do now! The thief can't hold back..."

At this time, there were gaps in Mako's position one after another. He was not stupid. He had the first-class ability to escape, so he directly asked the servants to come over there and hurriedly came to meet Wu Sangui.

Wu Sangui really wanted to kick Ma Ke into the city at this time.

What kind of things are there? There is not enough success or failure!

But at this time, Wu Sangui could only suppress the anger in his heart and comforted him: "Don't panic, have they not yet killed them? We have so many elite riders, are you still afraid of these mud legs? Master Ma, go and rest first, I will do it."

Seeing Wu Sangui's calm look, Ma Ke felt a little relieved and stopped harassing Wu Sangui. He hurried to rest first, mainly to prepare for a way out for escape.

After sending Ma Ke away, Wu Sangui was already so gloomy that he was no longer as human!

A decision must be made!

If you don’t make a decision, Shanhaiguan will be lost...

After a moment, Wu Sangui gritted his teeth and murmured: "My man surnamed Li, how can you kill me? How easy is it?! Let you see the real defense of Shanhaiguan!"

"Come!"

"yes!"

A personal soldier hurriedly knelt respectfully in front of Wu Sangui.

Wu Sangui's face was already ferocious and he said coldly, "Transfer our military orders to drive these dogs back and add tinder oil!"

The personal soldier's pupils suddenly widened, and he came to his senses for a moment, and he quickly said yes respectfully.

Soon, on the steps of the city wall, countless men rushed up with wooden barrels, and then followed the drainage channel to pour out the objects in the barrels, all of which were oily with indescribable smell.

But this is called "temperature oil", but it is not temperature oil extracted from model military oil, but is extracted after mixing pineapple oil and various animal oils.

This is the old technology of Jingying.

As a bucket of turmeric oil was poured out, it soon gathered into a river and slowly flowed towards various Luocheng directions.

This is the clever and powerful thing about Shanhaiguan’s design!

The main city is high, while the Luo city is low.

This design is difficult to see with the naked eye, mainly for drainage needs.

But at this time, Wu Sangui accurately grasped this point.

"boom!"

In the mixed rooms, countless tincture oil rushed to various Luochengs. Someone accidentally dropped the torch into the drainage channel. An explosion sounded suddenly, and a raging fire broke out.

"not good!"

"The Wu Thief wants to cheat!"

"Brothers, rush over and fuck them!"

"kill

(This chapter is not finished, please turn the page)

Wu Thief!"

"kill……"

The refugee army immediately noticed something strange, and many officers also made the correct decision at the first time, wanting to kill the Guanning army and pull out the space.

However, at this time, the Guanning Army had no way to retreat, so how could it be possible to retreat easily? They gritted their teeth and fought hard, stuck in front, just to prevent the refugee army from coming.

If Xu Changqing was here, he would be able to find the crux of both sides as soon as possible.

At this time, whether it was the refugee army or the Guanning army, when they were fighting together, they had close combat, there were mostly short weapons, and there were too few long soldiers.

However, short weapons such as waist knives are indeed convenient and skillful, but they are just small paths and are far from impact.

Even Guan Erye’s long sword, including the Qing army’s big hammer, hook and sickle, mace, etc., were all paths at this time.

Even though these weapons have impact, they are still too small, and they are more capable of controlling small fields.

Only spears, especially spearmen fighting groups with established structures and scales, are the kingly way in this environment!

Use the shortest time to break through the space, pull out the space, and squeeze the opponent's space!

Only by using the vigorous momentum of moving forward and driving the opponent out of the area that must be controlled can you achieve the maximum effect in the shortest time and achieve the final victory of the battle!

Unfortunately, both Li Zicheng and Wu Sangui are a little tender in this regard.

"boom!"

"Boom..."

During the melee, the fire in the drainage canal was constantly ignited, and the archers of the Guanning Army also followed, and rockets continued to shoot at the refugee soldiers in various Luocheng, which soon caused the fire to surge into the sky, and screams and shouts came everywhere.

Even though the refugee army was sharp at this time, how could it fight against this terrifying fire? When they had to retreat, the space that was desperately rushed out could only be returned to the Guanning Army.

After all, in terms of the comprehensive quality of the battlefield, even the old army of the refugee army is far from the Guanning army. Not to mention anything else, just riding and shooting is completely incomparable.

Among the cavalry of the Guanning Army, almost everyone is a good cavalryman, but how many people can there be in the refugee army?

"Dog thing, what a vicious thought!"

Liu Zongmin immediately discovered something was wrong and spat hard.

The generals who had been immersed in the state of excitement gradually calmed down and looked at Liu Zongmin in a hurry. No one of them expected this state.

Li Zicheng also became a little nervous.

This is really a crime of non-war.

Who would have thought that Wu Sangui would be so cruel in the end and would definitely have many people killed or injured in Guanning's army with such a firework.

In a moment, Liu Zongmin had already seen sweat on his forehead, so he quickly gave the first order and quickly removed the catapult cart, especially the flower bomb.

If the flowering bullet is not handled properly, it will really shoot yourself in the foot.

But the fire was so fierce that they could not rush forward any longer, and Liu Zongmin had a faint desire to retreat in his heart.

After all, I don’t know how much tincture oil will be consumed for a big fire of this size. Even Shanhaiguan will definitely not be able to store so much.

As long as you spend a little more, Wu Sangui will definitely not be able to withstand it if he attacks tomorrow.

But for some reason, Liu Zongmin always had a bad premonition in his heart. It seemed that something was wrong, but he couldn't remember it for a moment.

‘How to choose?’

Liu Zongmin was also unsure of it.

However, he suddenly became clever!

If Xu Changqing stood in his position, what would Xu Changqing choose?

Liu Zongmin couldn't help but squint his eyes hard and his mind quickly rotated.

Whether he asked someone to read military tactics to him or listen to others' tactics to him, after all, his ability at this time was more about understanding from actual combat and integrating it with his talent.

And there is nothing in these insights

(This chapter is not finished, please turn the page)

It is more profound than the memory left to him by Xu Changqing.

It is precisely because of Xu Changqing's existence that he himself can feel that he is much stronger than before.

As he thought about it, Liu Zongmin's eyes became more and more firm.

In this state, whether it is rash attack or giving up, it is unwise. The best way is to stretch it first!

After all, most Luochengs are on fire, but there are still a few that are not on fire!

Moreover, the combustion power of tinder oil is destined to be limited. If you support it, there may be changes?

After retreating from the catapult car, Liu Zongmin did not issue new orders to the elite refugee troops on the city, but asked the catapult car troops to continue to push forward and continue to throw flowering bullets from the gap between Luocheng to the place where the city was on fire.

"Bang!"

"Bang bang bang bang bang..."
