As early as half a month before the expedition, Sun Tu had created a batch of firearms based on the gunpowder newly prepared by those craftsmen that could inflict great damage on the enemy in a small area - a kind of grenade similar to that of later generations, but with a rudimentary structure, greatly reduced power, and at the same time required an open flame to ignite, which he called a broken bullet.

Because as early as when he planned to build firearms, Sun Tu's goal was to Liaojin and other countries in the north. When he knew that the Great Song army was far inferior to the nomadic cavalry in terms of combat power, and that it was no longer possible to resist their southern invasion with bows and arrows alone, the first thing he thought of was a firearm that was more powerful than a bow and crossbow, and at the same time easier to operate.

As a traveler, Sun Tu naturally knew very well how much firearms played a huge role in the history of warfare in the next thousand years, and it can be said that it was precisely because of the continuous improvement and power of firearms that large-scale cavalry operations were finally eliminated from the sequence of war.

Even if you don't mention the modern times when gun technology has been fully matured, the Ming Dynasty alone used the advantage of firearms to defeat and flee the Mongolian cavalry, and there was almost no power to fight back, which led to the decades of peace after Yongle.

It can be said that in addition to the equally sophisticated cavalry, firearms are the best choice that can restrain the invasion of the northern cavalry. This is the fundamental reason why Sun Tuhui spent a lot of time on it, and it is also the confidence that he dared to rush to the aid of Lingzhou with only three hundred veterans of the Qingzhou Army this time, and fought a battle with the powerful Jin Jurchens.

However, Sun Tu still overestimated the combat effectiveness of the other state capitals and township armies, and they fell apart and fled in all directions before they could even stop the enemy's first round of attacks, thus completely exposing themselves to the sword edge of the Jurchens, and also allowing him to use all the tricks at the bottom of the box in desperation.

However, judging from the effect of the devastation bullets, these improvised firearms are still worthy of his expectations, this kind of gunpowder as the guide, containing iron nails and iron sheets, relying on the impact of the explosion to shoot the enemy's weapons in close combat with the enemy actually showed extremely great lethality, dozens of devastation bullets smashed over, so that almost everyone of the Jurchen elites who came from both sides were injured, and many people were even more frightened, completely stunned, and could not come back to their senses for a long time.

This is also the collateral effect of this unprecedented use of firearms, this kind of weapon, not to mention the Jurchens, is the well-informed Song people have never seen it, the sudden explosion, the powerful lethality not only kills their bodies, but also shocks their minds, so that they don't know how to react in a short time.

Because in the eyes of people at this time, such a thunderous weapon can only be used by immortals, which will naturally make people fearful. And Sun Tu also caught their reaction in an instant, and immediately ordered: "Kill!" The enemy is being broken now! ”

It wasn't until they heard Sun Tu's order that the Qingzhou army, which was also frightened by the power of the broken bullet, suddenly woke up, and immediately roared again and again, waved their weapons and fiercely pushed forward, and went straight to the wounded enemies.

The group of people closest to the Qingzhou Army were the most seriously injured, and at this time they were still in a trance, but the enemy had rushed to the front, which made them have no time to react more, so they could only subconsciously raise their weapons, but after all, they were still half a beat slower, and suddenly the knives and guns entered the body, screaming again and again, and dozens of people fell in a pool of blood in the blink of an eye.

It was also at this time that after hearing the screams of the family members and seeing a large number of warriors being cut down and stabbed, the Garuhuabo brothers, who were also shocked by the broken bullets, suddenly came back to their senses and immediately ordered a retreat. Even if they were reluctant in their hearts, they had to admit that today's battle was still lost after all, although they defeated the vast majority of this Song army, but in the end they were still defeated by the last three hundred extremely elite Song troops!

Instead of choosing to fight to the end, they wisely made the decision to preserve their living strength, and quickly withdrew to the flanks and rear. At the same time, while retreating, they continued to drive the fleeing Song troops to the rear, using them to block the pursuit of the Qingzhou army, but those who refused to move did not hesitate to kill.

So, on this plain in the middle of the night, an extremely strange war scene was presented - on all sides were the Song army desperately fleeing, and behind them, there was a Jurchen army constantly pursuing, and forcing them to block back, and then in the rear, there was another Song army of several hundred people.

Unlike the first two teams, which were already scattered and embarrassed, the last 300-strong army kept a neat queue, moving forward at a uniform speed, and after lining up the comrades who were blocking the road on both sides, they continued to pursue the Jurchen army that was fleeing in front of them.

At this time, Sun Tu naturally couldn't easily let go of this invading Jin soldier - at this time, he could already confirm that the team with such combat power and discipline could not be the strength of a certain Jurchen tribe, but from the Jin court, which had the greatest threat to the Great Song Dynasty, they were real Jin soldiers! - This is not only because they have killed too many of their own subordinates, so that he must take revenge, but also because today he has exposed his hole cards, which is a trick that must continue to hide, at least a top secret that will not be known to the future enemy of the Jin Kingdom.

Sun Tu could already imagine the key role he could play in killing the Jin army by surprise with firearms when the two sides officially started the war. But once the Jin people knew early on that the Great Song Dynasty had such a weapon and had some preparations, then this advantage would be gone. So no matter what, he will completely annihilate this Jin army today, leaving no one behind!

"Kill, ......" The chase battle between the two armies of Song and Jin was staged, and the two sides fought all the way and kept running forward, but they kept going in the direction of Lingzhou. At this time, it also began to test the results of the daily training of these two elite divisions of the world, although these golden soldiers are good at running because of their perennial fishing and hunting life and many years of fighting with the Liao people, Sun Tu and the Qingzhou army are no worse than them, and the hard training that has hardly stopped for several years has been completely fulfilled today, and there is no intention of being distanced by the enemy at all.

Especially after the front side no longer had the previously dispersed rout soldiers to delay the footsteps of the Qingzhou army, Jin Bing was surprised to find that the distance between his own family and the Song army was getting closer little by little.

"Hua Mo, you take the lightly injured people to go first, and if you are seriously injured and can't run, stop them with me!" After realizing that he would be overtaken if he ran any further, Garu Huabo decisively made the wisest choice, quickly stopped and turned around, raised his knife over the top, and after taking a deep breath, he had already let out a loud cry and rushed forward in reverse.

Many of the soldiers who knew that they were not lightly injured turned around without hesitation, and followed Hua Bo to kill the Song army that was getting closer and closer, and Hua Mo, after being stunned for a while, gritted his teeth and continued to run forward with a hundred or so clansmen who were unhindered. Originally, he planned to be cut off by himself, but since his brother had already taken the first step to fight back, in order to live up to his sacrifice, he could only be a coward and lead people to continue to flee for his life.

The Qingzhou army, which was chasing the Jin soldiers, immediately knew their thoughts when they saw the hundred or so Jin soldiers who suddenly turned back to kill, and Sun Tu also made a quick decision, ordered to stabilize the formation, and slowly pressed forward. Although there are only a hundred people in front of them, they are the elite of the Jin army that can crush thousands of officers and troops in one fell swoop, and now they are still holding the heart of death to block, so there must not be the slightest sloppiness!

Seeing that the Qingzhou Army, which had slowed down and was in full formation, Garu Huabo, who was striding forward, showed a trace of regret on his face, the other party didn't even give him this opportunity. There's no way, so let's go all out!

The idea was set, his feet were strengthened again, his body rushed forward like a whirlwind, and there were still ten steps away from the enemy, and the long knife that was more than one person high had been picked up by him, and he shouted loudly: "Can General Song dare to fight with a certain battle?" ”

What he said was an authentic Jurchen language, and the Song army in front of him couldn't understand it at all. In fact, even if he understands, Sun Tu will not take it seriously, and at this time, a fool will play a heads-up battle with the enemy. Although Sun Tu was confident that his martial arts were enough to take his life in a one-on-one battle, as the main general, how could he risk any knight duel with the enemy?

Not only did he not respond to the other party's challenge, but instead shouted in a low voice as he watched Hua Bo shoot closer: "Crossbow arrows, shoot me!" "Now that the two armies are at war, what they want is to kill each other as quickly and easily as possible, and that is the best and most correct means.

This time, half of the veterans of the Qingzhou Army who came with Sun Tu prepared a newly created firearm, a captive bullet, and the other half carried another big killing weapon, a repeating crossbow. However, this crossbow also has the same defect as the Destruction Bullet in that the killing range is too small, so it was not able to be used just now.

But now, when the enemy is rushing at him like moths to the flames, it gives the repeater a perfect opportunity to put it to use.

The sound of "snorting" broke through the space, and dozens of short arrows had quickly flown out and shot straight at the enemy in front of them. This time was really much beyond the expectations of Hua Bo and the Jin soldiers behind him, they really didn't expect that the Song army would release arrows at this time, you must know that they actually had the opportunity to release arrows just now, but it was useless, until everyone relaxed their vigilance, they released the arrows.

"Despicable ......" Hua Bo and the other Jin soldiers roared loudly, wielding the weapons in their hands to block the frame, and at the same time rushing forward with all their feet, hoping to kill the Song army and make their bows and arrows useless.

However, what they were facing was a five-arrow repeater, and the large net woven by nearly 500 sharp arrows like a dense raindrop could not be broken through by a hundred people at will.

The screams kept sounding, and in the end, there were only more than a dozen people who rushed to the Qingzhou army, that is, Hua Bo was hit by two arrows......
