Song Beiyun

This blow really caught the Jin army at the forefront by surprise, and many Jin troops fell to their deaths on the way forward.

But soon the Jin Army reacted. They rolled out a very weird cart from the camp. This cart was about three meters high and five or six meters wide. There were three layers of shields stacked in front of the cart. Protective devices, neither muskets nor crossbow bolts can penetrate.

The only thing that can effectively kill them is the artillery, but the loading speed of the artillery is really unsatisfactory, and the artillery used on the wall is a light artillery specially prepared for mobile warfare. The army's own heavy artillery for defending the city is not a thing. Its main purpose is to blast cavalry on the grassland.

After seeing the situation on the battlefield, Song Beiyun narrowed his eyes and said, "This is really amazing."

Song Beiyun, who seldom praises people, directly said that this time it was amazing, because apart from the first batch of troops, the serious Jin army behind them was actually using a very advanced squad-based skirmishing method!

This tactic was obviously born to restrain Song Beiyun. It should be the experience that the Kingdom of Jin gained from the battle between Song Dynasty and Xixia, and after research and grinding, it created this tactic that does not belong to this era at all.

Just like Song Beiyun created weapons that do not belong to this era, smart natives will definitely create tactics to restrain those weapons. In a sense, Song Beiyun has unintentionally promoted the evolution of military tactics in this era.

Skirmish advance tactics can actually effectively enter the blind range of the artillery position.

It seemed that he knew everything, if he wanted to win Song Beiyun, he had to fight him face to face, otherwise there would be no chance.

As for the battle damage, he didn't care at all. With a 35 army against a 5 city defense, as long as six people replaced one of the opponents, he would still have a full [-] people left!

The skirmish line was outflanking upwards from all angles, and soon came to the blind spot of the artillery position. Although many people were lost on the way, they were finally approaching.

But at this moment, Xiao Song gently raised his hand...

In an instant, the hand-operated trigger explosives that detonated from the city suddenly exploded. At that time, smoke and dust, earth and rocks flew everywhere, and countless soldiers of the Kingdom of Jin were blown out by the huge impact. Some people were even blown to pieces on the spot. The power of the shaking of the mountain and the shaking of the ground alarmed Wanyan who was in the distance. He walked into the formation and looked towards the direction of Juyongguan, but he only saw a cloud of smoke and dust, and ignored everything else.

"It's not good, handsome!"

The messengers rushed to the camp of the Jin army and shouted in a hurry: "The Liao army used the magic method, and the soldiers were killed and injured countless times!"

"Demon skills." That Han murmured softly: "Hmph, I want to see how many demon skills he has, and continue to order people to rush up. If he is negligent, he will definitely kill him."

There are really not many explosives used to break the city, and there is only such a chance for deterrence, but after the smoke and dust cleared, he found that the Jin army was still attacking forward like a tide, so he took a step back.

"Incendiary bomb."

Since kerosene has been invented, it is of course necessary to use it. Although Xiao Song doesn't really want to use such a conscienceless thing, this is war.

The incendiary bombs packed in glass bottles are not the yellow color of kerosene, but brown, because there are not only kerosene but also not so pure gasoline in it, plus white sugar, glacial acetic acid, white phosphorus and potassium nitrate for making fertilizer.

The soldiers threw the packaged glass bottles under the city, and they didn't need any precision. They just threw them down, and let the liquid inside splash as the glass exploded. Then, due to the violent collision, the potassium nitrate exploded first, and the explosion exploded. The white phosphorus was ignited, and then the mixture on the ground was ignited. Almost instantly, a wall of fire appeared on the ground in front of the pass.

As long as Jin Bing comes into contact with this kind of flame, it will continue to burn, and it cannot be extinguished no matter how it rolls or how. Instead, it will burn more happily because it is contaminated with white sugar and white phosphorus.

If it is contaminated on the skin, a large piece of flesh will be burned off soon, and there is a strange smell in the air, the smell of burning flesh and the pungent smell...

The one who saw this scene in the distance clenched his fists tightly. He lost more than two thousand people in just the first round of contact.

This is what he never expected...

"Report!"

The messenger quickly reported: "The Liao Kingdom once again used the demon method to rain down the fire from the sky. Our soldiers would burn to death as long as they touched it. Those who survived were also in great pain and wailing, and some even committed suicide before the battle."

Wanyan that Han stared at the front in a daze, gritted his teeth and said, "Damn it! Send an order to go down and divide a part to go to other passes."

"Yes."

Wanyan obviously wanted to try his luck. If there were no people like Song Beiyun guarding other passes, he would pretend to attack Juyong Pass, and then concentrate on attacking other passes.

And Xiao Song is also worried there, because he really doesn't have many "monster spells" at hand, and this place can't be supplemented at all. If the person on the opposite side who can create skirmishers finds that he is strong outside, then the other party may really be Will attack like crazy.

There are 35 people on the opposite side. Even if six are replaced by one, there are still 5 people left.

Xiao Song sat in the barracks, quietly waiting for the news from other checkpoints. After this wave of tentative attacks, if the opponent was not a reckless person, it should calm down a bit. Anyway, as long as you don’t start Let them attack and siege the city as they please, anyway, as long as the reinforcements arrive, everything will be fine.

But this Xiao Song actually didn't dare to pat his chest to make a promise, because Xiao Song could understand how the Wanyan and that other on the opposite side lost their beloved daughter, and how he felt.

So, he actually regretted it a little now, and shouldn't have discussed with those strong-headed fools whether they should kill the kidnappers. Those dogs from Qiu Ba had a brain the size of a walnut kernel. How could they know what politics is?Now I'm losing face, and I'm about to lose my face.

Of course, Xiao Song is the most responsible here. At that time, he didn't think too much about the consequences in order to pretend to be coercive, but now he may have to drag the whole Yanjing to bet with him. , Juyongguan defenders will be beaten to a mental breakdown within five days at most.

"No, I won't listen to what these idiots say in the future."

After shaking the pot to make himself less stressed, Xiao Song started to pick up the idle book and read it. It's the same thing if he reads it or not. Anyway, he has to let his subordinates see that he is leisurely and relaxed.No matter how your feet flutter, you must be as graceful as a synchronized swimmer.

"Lord Song, one of the enemy troops turned around and headed for Badaling."

"Let's go, let's go, so what about Badaling? It will never come back." Xiao Song said with an expression that Lao Tzu had already seen the opportunity: "What news is there in the city?"

"No."

Ok……

Why haven't the reinforcements come yet! ! !Xiao Song was roaring in his heart, he is so scared now!Afraid of death, really afraid of death.If the reinforcements don't come, he won't be able to sleep at night!

"Report!"

Before the previous commander left, another commander came in: "Report to the Marshal, the Zuopishi Army has arrived in Xinzhou."

"Are you in Zhangjiakou?" Xiao Song smiled after finishing speaking, and subconsciously said the name of the future: "Okay, ok, ok."

Chapter 628: Four Years November 11

Juyongguan still stands there, unbreakable.The offensive and defensive sides have nothing to do with each other, they can only smash each other with long-range weapons.

But obviously the Jin army was more anxious, because they knew that the reinforcements from the Liao Kingdom would arrive in a short time, and once the Song-Liao coalition forces arrived, it would be too late.

"Hold……"

Song Beiyun was sitting in the big tent listening to the noises outside, when suddenly a stone the size of a man's head fell from the sky, smashed through the ceiling, and landed in front of him, scaring him into a shudder.

Afterwards, the soldiers rushed into the big tent to protect Marshal Song, but Xiao Song just waved his hands and didn't say anything.

"Have you found out, why Jin Guo's engineering equipment has such a long range?"

The question Xiao Song asked was just this question. If it was a bed crossbow, that would be fine, but the one on the opposite side was obviously a trebuchet, but can the trebuchet really have such a long range?This must be more than 500 meters, which is already twice as far as the normal range of the catapult.

And this thing hits a parabola. These golden soldiers took advantage of the terrain around Juyongguan to avoid the sight of the cannons and hid in the depressions all day long to throw stones into Juyongguan. Who can stand it? It took Tian to outflank from the flanks, and it took Song Guo's younger brothers about 20 days to arrive.

"Marshal... I really don't know, my Liao Kingdom suffered a lot from this thing back then."

Xiao Song thought about it for a while, and looked at the rainy ten yuan in the sky. He put his hips on his hips and remained silent for a long time.

"Sun Shepherd, come here!"

Not long after, the general in charge of the logistics of the artillery battalion of the Beihai New Army ran over with his head covered.

He was originally a sheep herder, and later learned forging in the Jinling Workshop, and was transferred to the Beihai New Army to be responsible for equipment maintenance. Everyone called him Sun Fangyang, but he had forgotten his real name.

"Master, what are you doing?"

"What are you doing!" Xiao Song slapped him on the helmet, "Why are you asking me! I am being hit every day, why are you asking me! What about those gangsters from the Engineering College? Let me call them come over."

"Yes!"

Sun Fangyang quickly turned around and ran over. After a while, he ran back with a few young people.

"You guys." Xiao Song pointed at the young people: "Within two days, get me something that can kill the catapult camp on the opposite side, or I will let you go back to the math school to eat shit!"

These boys were driven crazy in the math college before they left the engineering college and then joined the army. Letting them know the math college is more painful than killing them. They said it when they came out, and they will eat it when they touch math in the future Shit, that thing was born as if to prove that they were fools.

But today... Xiao Song gave them a death order, and this group of people was a little confused, killing the trebuchet on the opposite side, how do they do this?

Firstly, the opposite side was in a low-lying place, and it was not realistic to use a cannon to shoot at this angle, and they couldn't hit other things, so it was difficult for them.

But the death order has been issued, one day?Isn't this clearly embarrassing?But they all followed Song Beiyun all the way out of Jinling. How could they not know the nature of Master Song? He said he would send them back to the School of Mathematics, so he would really send them. They couldn't bear that grievance.

Since I can't bear the grievance, I can only do it.

After receiving the order, these people turned their heads and entered the equipment warehouse and began to fiddle with them. They were drawing pictures and thinking of ideas, but when it was approaching the middle of the night, the stones outside were still smashing, but they didn't come up with a good idea. method.

"Hey, what do you guys think if you use that lightning guide?"

"Can you throw the lead mine a mile away?"

"Throwing, we can throw it out."

A few people talked to each other, but they figured out a more feasible direction, which is to throw the shells of the heavy artillery. The shells of the heavy artillery will explode, and the explosion power is not small, enough to razed those catapult positions. Flat land.

But the only thing they worry about now is that there are shells in the warehouse, but there is no suitable gun. After all, that kind of city defense gun can't be moved easily, let alone take it out and use it at will.

"Based on the level, the muzzle is raised by 85 degrees, and a heavy gun with a low charge can just hit the opponent's trebuchet camp." One of them put the calculated data in front of the group of people: "Now the problem It is how to find a substitute for heavy artillery."

Yeah, the substitutes suck... there's nothing to substitute here, thick bamboo?Obviously it is not possible, because the gunpowder explodes in the barrel to generate extremely high pressure, if it is not for the steel, it is absolutely unbearable, and even the stubborn stone will be blown apart.

"Well, I have an idea."

Someone slapped his head and said, "The launching part of the heavy artillery is much larger, so why don't we just use the warhead to launch it?"

"Did you learn to be stupid? That thing will explode, and it can withstand the bombardment of gunpowder?"

The companion's warning made the guy sit there and meditate: "This is really difficult..."

Several people lamented at the same time, and the time had come to the fifth watch, and there were dismantled cannons and shells in front of them.

"It's not a solution for us to stare like this." The most calm of these people opened his mouth and said: "I have a way, we can find a way to reduce the shock, as long as we push the shells out."

"Then you said it."

The man took the draft paper and quickly drew a schematic diagram. The meaning is to use only the warhead of the heavy artillery shells, plus the barrel of the light artillery, so that it can be completely inserted into the barrel with only a little polishing. However, they do not use gunpowder to propel directly, but fill the warhead with animal skins as a shock absorber. When the gunpowder explodes, the impact force will be absorbed by the animal skin, reducing the vibration and reducing the vibration of the shell. Warhead pushed out.

"What we want is the angle rather than the strength, right? It doesn't need to be able to hit the ground like a heavy artillery. It just needs to be able to reach the people behind the hillside, right?"

His proposal was immediately responded to, so several young people with strong hands-on ability immediately started to operate.

They illuminated with torches, and then raised the barrel of a light cannon with cushions, so that the muzzle stood up high, and after measuring a rough angle with carpenter tools, they began to accurately load gunpowder and trimmed guns into the muzzle. hides.

After everything was ready, they roughly calculated, then removed the warhead of a heavy artillery shell, carefully stuffed it into the muzzle, and then anxiously took out a huge long fuze and inserted it into it .

After evacuating to a safe location, they ignited the fuse...

With the roar of artillery, Xiao Song jumped up from the camp bed under the city wall.

"Who is firing indiscriminately!"

As soon as the voice fell, he heard an explosion from outside the city wall. He immediately put on his armor, went up to the tower and picked up a telescope to look over. Not dissipated.

And just when he was puzzled, there was another cannon sound in the pass, and this time the cannonball advanced to a place less than ten meters away from the catapult position.

When Xiao Song saw this scene, three bright characters appeared in his heart—mortar.

Before he could check it, he heard a third sound. This time, the cannonball hit the trebuchet field firmly, and he saw a burst of flames rising into the sky in the field, followed by a loud sound. The sound, that place was almost bombed to the landslide.

"So awesome?" Xiao Song put down the binoculars in astonishment: "Who is firing the cannon? Take me to have a look!"

Immediately, the officer asked questions level by level, and then someone came and took Song Beiyun to the place where the cannon was fired.

Before reaching the supply camp, I saw a man standing on the edge of the city wall and shouting: "Left 37 degrees, height 81 degrees, two-thirds of the charge."

After the coordinates were set, the lower head immediately began to adjust the direction of the erected cannon, and then fired another cannon.

When the sound of an explosion was heard outside the city, the observer on the city wall shouted: "Three degrees to the left!"

The muzzle was adjusted slightly, the charge was re-weighed, the barrel was cleaned, and the gun was loaded. After everything was ready, it was fired again.

"Hit. 45 degrees left, 72 degrees high, two-thirds charge!"

At this time, the sky was already bright, and only such password information could be heard at the supply camp, and Xiao Song didn't bother, but just watched quietly from a distance for a long time.

It turned out to be a mortar...

Although this mortar is a bit rough, and the probability of bombing can be [-]/[-], it is indeed a mortar!

This group of people actually made the mortar in one night. Although there is a big gap with the mortar Song Beiyun imagined, but to make this thing under such circumstances, isn't this a genius?

After the visibility was high, the hit rate increased significantly. Xiao Song stood outside and watched them operate. It took about five shells to destroy a Jin Army's trebuchet before, but with the proficiency of the operation and the increase in the experience of the observer, Now it can basically be controlled at about three rounds to destroy a trebuchet.

Although the bombing happened from time to time, and each time the bombing was equivalent to a waste of a cannon, this group of young people seemed to be afraid of death in the same line as Song Beiyun. The length of their fuze was enough for them to run a hundred meters. He also used the spare bricks of the city wall to build a protective circle, for fear that he would be blown up.

"Stop tossing my cannon."

Finally, after they knocked out the tenth trebuchet position and destroyed five cannons, Xiao Song finally spoke out in distress.

And those young people who were immersed in the pleasure of having a cannon realized that their beloved Lord Song had stood there at some point.

"Master Song, when did you come?"

"When you blew up the first chamber."

They looked at each other, but they didn't speak, and the baggage camp behind them was already in a mess. Although the shells were not here, the roof of the temporary hut had already been ripped off, and weapons and armor were scattered on the ground.

"Master Song, we have done everything you ordered!"

Looking at their proud faces, Xiao Song didn't pour cold water on them, but said after a while of silence: "Can you find a way to blow up the other party's camp?"
