The Jin army dug three tunnels, the left and right two dug in the underground river, was poured by the river water, it was abandoned, which is also the reason for the serious drop in the water level of some wells in the city, luck is good, the tunnel in the middle has been smoothly excavated to the bottom of the city gate, after placing a bucket of explosives, Huang Taiji is ready to attack, and when Zhao Shujiao found out that the situation was not good, it was too late, the city wall of the city gate section was blown down, revealing a gap of nearly twenty meters wide, and the bones of a team of soldiers patrolling and guarding on this section of the city wall were gone, Lu Hongniang, Zhao Shujiao and the others are considered lucky, one step slower, otherwise they will be finished if they climb to the top of the city.

The violent explosion frightened the galloping war horse, and stood neighing, several guards were caught off guard, and they were injured immediately after falling, Lu Hongniang reacted quickly, jumped up, and landed safely, while Zhao Shujiao took some effort to forcibly control the frightened war horse.

The earth-shattering explosion was the signal of the attack, and the iron cavalry of the Jin Army, which had long been ready to attack, rushed out and charged towards the gap, and similarly, the people in the city were also frightened and woke up, but fortunately, the soldiers of the Phoenix Legion and the government soldiers of Shanhaiguan had been ordered to set up and rush to the preset position under the command of the officer.

Because the Jin army attacked the city, even if it was a feint, Lu Hongniang still didn't dare to be careless, and the soldiers in the city had been waiting for him, and there was a large group of soldiers left in the hidden pit under the city wall in case of accidents.

There were more than 200 soldiers stationed in the Tibetan pit in the collapsed section of the city wall, half of them were soldiers of the Phoenix Legion, and half of them were soldiers of Zhao Shujiao, all of whom were killed, which was the largest casualty since the formation of the Phoenix Legion.

Hundreds of soldiers in several other Tibetan pits all poured out, and under the command of Lu Hongniang, some of them rushed desperately to the city, and some of them rushed to Lu Hongniang and Zhao Shujiao to line up.

Fortunately, the soldiers of the Phoenix Legion were well-trained, and after a short period of panic, they quickly lined up under the command of the commander Lu Hongniang and loaded their ammunition.

At this time, the sky has slowly brightened, although the line of sight is not very clear, but the field of vision has been far away, both sides are snatching time, the Jin army outside the city is charging on horseback, the soldiers in the city are desperately running towards the city, and some are rushing to the broken walls on both sides, nervously loading ammunition.

In the billowing dust and smoke, the black iron horses swept in like a flood without embankments, and the rumbling iron hooves struck the heart like a heavy hammer, and the whole earth shook.

"Listen to my orders, and prepare for the thunder."

Lu Hongniang ordered an officer to command the soldiers who had almost lined up in the phalanx, and she and Zhao Shujiao rushed to the city, she shouted loudly while running, at this time the sound of hooves was very close, she had no time to rush to the city, so she had to order more than a dozen soldiers who rushed to both sides of the broken wall to prepare to throw thunder.

The thunderous rumbling sound of iron hooves seemed to explode in his ears, and the iron cavalry of the Jin Army at the forefront had rushed into the gap at a rapid pace.

"Throw!" Lu Hongniang broke off, the short gun in her hand burst into fire, and among the dozen or so horsemen who rushed in, a war horse neighed sadly, threw off the knight on his back, and then fell down with a bang.

More than a dozen female soldiers guarding beside her also pulled the trigger one after another, the explosion of short guns and ping-pong in their hands, spewed out clouds of whistle smoke, and from time to time there were war horses neighing and falling, and more than a dozen soldiers holding thunder in their hands lit the fuse with torches and threw them at the enemy horses who poured in like a tide, but they did not explode immediately, and one by one the thunderbolts fell on the gravel, and there was green smoke emitting.

"First row, shoot!" The officers standing beside the formation and commanding shouted loudly.

Bang bang –

The soldiers in the first row pulled the trigger almost at the same time, ping-pong fired the platoon guns, and then without looking at whether they shot down the enemy, they quickly retreated and loaded their ammunition, while the soldiers standing in the second row took two steps forward, raised their arms and aimed their guns, and the soldiers in the third row followed two steps forward and became the second row.

I don't know how many times I have practiced these movements, I have long been familiar with it and become a habit, although I am nervous at the moment, I am not flustered, and I am not afraid, although there are some recruits in the team who have not yet been on the battlefield, but under the influence of many veterans around me, they have gradually settled down and meticulously obeyed the orders of the officers.

In the first wave of guns, more than a dozen horsemen who rushed in first fell with a bang, and the mournful neighing of the horses and the terrible screams of the people rang out.

The iron cavalry of the Jin Army was still surging like a tide, and more than a dozen thunderbolts emitting green smoke just exploded one after another, blowing up the flesh and blood of the Jin soldiers who poured into the gap, and the billowing gunpowder smoke and thick smoke once covered their vision.

"Shoot!"

Regardless of whether they saw the enemy or not, the officer commanding the phalanx still ordered the soldiers to shoot, block the gap with a dense rain of bullets, prevent the Jin army from breaking through, and buy time for their comrades as much as possible.

At the time of the three rounds of guns, the soldiers who climbed the city also rushed to the head of the city, or picked up the stones and threw them under the city, or stood behind the battlements and shot them, or opened their bows and arrows, desperately shooting the enemies who came in a frenzy, the targets were very dense, and they could shoot a target with their eyes closed, for fear that you would not shoot fast enough.

"Boom, quick."

The officer who led the team shouted loudly, there were too many enemies to kill, at this time with muskets, bows and arrows were too slow to shoot, the lethality was not enough, the rate of fire of the cannon was too slow, and it had entered the blind spot of the cannon's firing range, only the thunder was the most lethal.

One by one, the thunderbolts smashed down from the city with a sigh of green smoke, exploded in the dense crowd, the stumps and broken arms were thrown, blood was splashed everywhere, and the screams were endless.

The Jin soldiers who poured in through the gap were shot by the soldiers on both sides of the broken wall, and they were bombarded by a denser rain of bullets and bullets in the front, and all of them fell, and the corpses of people and horses were lying on the broken bricks and rubble.

Boom Boom Boom –

After lowering the elevation angle of the ten Franc machine guns on the head of the city, they roared one after another, killing and wounding the enemy with heavy artillery fire as much as possible, and blocking the charge of the enemy's iron cavalry, relieving the pressure on the comrades who were defending in close combat.

If you want to become an artillery officer or commander, you must at least be familiar with and understand these theories, the artillery of the Phoenix Regiment, the artillery of the Phoenix Regiment, has experienced several artillery battles, the theories in the manual have also been demonstrated, the actual combat ability has also been improved, and the vision is naturally much higher.

At this time, the soldiers of the Phoenix Legion rushed to the city, or climbed to the head of the city to join the battle, or took turns shooting the enemy on both sides of the broken wall, or fought in formation at the gap under the city, blocking the gap with dense bullets and preventing the Jin army's iron cavalry from breaking through.

The city wall was blown down nearly 20 meters wide gap, the gap is full of broken bricks and rubble, plus the corpses of the dead people and horses are piled up on the ground, and a low obstacle is also formed invisibly, the war horse gallops in, accidentally may stumble and fall, the whirlwind rushed in the war horse has more than a dozen stumbling and falling, breaking the leg bone, and also throwing the knight on the back away, the unlucky one broke the neck bone, and died on the spot, the lucky only broke the hands and feet, and then the thunder that kept throwing down the bones of the corpse.

However, the Guanwai clan is good at riding archery, they charge and shoot arrows at the same time, and more than 20 soldiers of the Phoenix Legion and Shanhaiguan Prefecture guarding both sides of the broken wall have also fallen from arrows, some of them died on the spot, and the lucky ones were only wounded, and they were carried aside by their comrades, waiting for the medical soldiers to treat them.

With the accumulation of more and more human corpses and horse corpses in the gap, it is no longer conducive to the gallop of war horses, the Jin soldiers have to dismount and fight, although they are very brave, one after another, but the speed of the charge has decreased significantly, and it is no longer possible to cause great pressure on the Ming soldiers defending the city.

Groups of soldiers who rushed to the city either went to the city to fight, or carried cloth bags full of mud and sand to pile up fortifications in front of the phalanx in front of the gap, or threw them at the gap, and the trees, tables, chairs, stones, etc. were all in a mess, desperately blocking the big gap.

There was no need for people to call for it, and the young and strong people in the city spontaneously rushed in, under the command of the officers, carrying tree stumps, stones and other things, desperately throwing them into the gap, trying to plug the gap, they all knew in their hearts that once the city was broken, the end would be very miserable, either killed by the murderous Jin soldiers or plundered as slaves.

"Fire, fire!"

In the distance outside the city, Huang Taiji hissed and roared, looking a little angry, the city wall was successfully blown up a large section, everyone was excited, they all thought that the dangerous city of Shanhaiguan was within reach, but they did not expect the resistance of the Ming army to be so tenacious, and they held the gap to the death, so that the elite iron cavalry of the assault suffered heavy losses, and he had no choice but to order the iron cavalry to continue to charge, and at the same time ordered the infantry to carry various heavy siege equipment such as ladders and siege towers to climb the city wall to fight, and concentrated only a dozen cannons to bombard the gap.
