"Boom~" With a loud bang at the gate of the city, the siege tube was finally detonated, and the Liao army at the head of the city of Xijin Mansion was also killed and wounded, and even some Song troops who had not had time to retreat were also injured by mistake, after all, the shock wave generated by the explosion of this thing was enough to shock people's internal organs.

Among the Song army outside the city, Liu Ping and the generals held binoculars to look at the smoke-filled city gate of Xijin Mansion, today's wind was very strong, and the smoke and dust were blown away after a while, only to see that the city gate was indeed blown up, but the masonry behind the city gate was revealed.

"Sure enough, the city gate was blocked, and it looks like the city wall can only be blown up!" Guo Zun looked at the masonry behind the city gate and couldn't help but sigh and said, they have blown up the gate of the Liao army city before, and Han Nanwang in the Xijin Mansion will definitely be prepared.

"Artillery ready!" However, Liu Ping, who was the main general, did not show an expression of surprise, and then ordered again with a wave of his hand, they have been coming to Xijin Mansion for a few days, and after resting, it is time to launch a general attack today.

The artillery that had already been prepared in the army also began to be loaded immediately, this time Liu Ping brought a total of fifty artillery, which had been used once before when crossing the river, but that time failed to show the true power of the artillery, and now the city of Xijin Mansion in front of him that could not move was the most suitable target for artillery.

"Put!" With Liu Ping's order, the artillery general also immediately ordered to fire, and then fifty artillery pieces let out a thunderous roar, all the shells were concentrated in the position of the city gate, although the city gate hole was blocked, but it is still the most vulnerable point in the entire city wall, as long as the firepower is enough, you can blast out a gap here.

However, Liu Ping soon discovered that all artillery salvos were very flawed, because there would be a pause after the artillery fire, which would give the Liao army on the city wall a chance to breathe, combined with the three shots of the muskets, he also immediately ordered the artillery to be divided into arrays, and then take turns firing.

This is also the first large-scale centralized application of artillery, even the artillery generals have little experience, fortunately, Liu Ping is very fond of artillery, and has personally studied artillery, so this time the artillery is also personally commanded by him, but he has found a suitable way of combat.

Dozens of artillery shells continued to bombard, which also made the Liao army at the city gate untenable, after all, some shells also hit the city head directly, and finally forced them to evacuate, and the city wall at the city gate was also bombarded and constantly collapsed, and the earth and stone blocked in the city gate hole were splashed everywhere, and they were about to be penetrated.

"Quick! Plug the gap! Han Nanwang at the head of the city saw that the city gate was about to be opened by artillery, and immediately shouted anxiously, and the Liao army who received the order immediately began to pile up earth and stone from the inside of the city gate, but it was too late, most of the earth and stone at the city gate had been blasted open, and the city gate hole had been opened, and the Song army outside the city could already be seen from the city.

"Kill!" Seeing that the city gate hole was blasted open a hole, Liu Ping also immediately ordered, and then saw the vanguard army as a death squad rushing towards the city gate, the Liao army at the head of the city naturally would not easily let the Song army approach, long arrows fell like raindrops, and the boulders thrown by the stone thrower also flew in the sky, and the ground was full of blood and corpses, and the cruel war finally began.

However, the artillery and bed crossbows on the side of the Song army are also exerting power, and the casualties of the Liao army at the head of the city are not small, and the Song army that rushed in front of it finally approached the city gate, and even someone has rushed into the door, and then climbed the bricks and stones to kill from the gap, because the bricks and stones at the gap are very high, and the war horses can't pass at all, so the first wave of charges are all foot soldiers, in fact, cavalry is rarely used when attacking the city, unless the city gate can be opened a gap for cavalry to enter and exit, and then cavalry will be used to sweep the city.

With the Song army entering the city from the gap, the Liao army in the city also organized a stubborn resistance in Han Nanwang, although the Liao army's strength is insufficient, but now there is only one gap, and the Song army that kills in is also very limited, so he can also organize enough troops to counterattack, and even wipe out all the Song troops who rushed in at the city gate.

"Boom boom boom~" But before the Liao army approached, the Song army that killed in threw out a series of grenades, and the Liao army was turned on their backs, and the Song army took the opportunity to break out of the gap and began to expand the area under their control, and the Song army in the rear was a steady stream of killings, and finally even the musket army rushed into the city, which accelerated the expansion of the Song army.

Seeing this situation, Han Nanwang at the head of the city finally couldn't sit still, and immediately went down to the city to personally command the defenders in the city to counterattack, and as a result, the two sides repeatedly fought for the position at the city gate, and the Song army was driven back to the city gate several times, but in the end it was still firmly guarded in the city gate hole and refused to retreat, and there were more and more reinforcements behind, and finally the Song army concentrated a charge, and the Liao army that came to aid was defeated at once, and the entire area near the city gate also fell into the hands of the Song army!

"Clear the gates and enter the city!" Liu Ping, who was outside the city, saw that the city gate fell into his hands, and finally showed an excited expression at the moment, and then ordered again, and the masonry at the city gate was also quickly cleaned up, as long as a road could be cleared, and then the entire army entered the city, which also meant that the city of Xijin Mansion was broken, and the goal of sending troops this time was also half completed.

As more and more Song troops entered the city, Han Nanwang also showed an anxious expression at this time, although the city is broken does not mean that they will definitely lose, at least now most of the city of Xijin Mansion is still in his hands, and he still has a chance to counterattack, for example, now that it is almost dark, he can take advantage of the night to organize a counterattack, as long as the Song army is driven out of the city, and then the gap is plugged, there is still a chance to turn defeat into victory.

But although the plan was good, Han Nanwang didn't have any confidence in his heart, because he found that the Song army in front of him was completely different from the Song army in his previous impression, especially the other party's main general was very disciplined in using troops, and he was also very cautious, since the other party had already entered the city, he would definitely not withdraw easily, and it would be very difficult for him to implement his plan.

The artillery was roaring, suppressing the Liao army on both sides of the city gate, and the Song army also quickly cleared the road out of the city gate at this time, and then a large number of troops poured into the city, and began to rush outward, the Liao army also arranged defenses on the streets of the city, wanting to block the Song army at the city gate, for which the two sides also launched a brutal street battle, the streets near the city gate were full of soldiers fighting, and the whole street was covered with blood and corpses.

"Kill!" Di Qing cut a Liao general off the horse with a knife, but then he was thrown off the horse by a Liao army, and then several spears stabbed him, but Di Qing was a roll to dodge, at this time his men also came to the rescue, he also drew his waist knife to join the battle group, and resisted the footsteps of the Liao army's charge.

"Retreat!" With the shouts of the rear generals, Di Qing and others, who were fighting with the Liao army in front, also immediately retreated, and then saw a row of musketeers come forward, the gunshots of "Woo Woo Woo" rang out, countless Liao soldiers screamed and fell off their horses, and the wounded war horses also kept neighing, and as the musketeers advanced with their guns, Di Qing and they finally took a breath.

The streets are too narrow, and there are too many obstacles, and the Liao army is familiar with the terrain, and often kills a cavalry from a street corner coldly, and the musket army is sometimes underprepared and cannot form a three-stage formation, so Di Qing personally led a team of men and horses to block the Liao army and buy time for the musketeers behind him.

Musketeers have advantages and disadvantages in street fighting, the good side is that the streets are narrow, and the enemy gathers together when they rush to kill, which is more conducive to the power of muskets, but the disadvantages are also obvious, there are too many obstacles, which will seriously obstruct the sight of the musketeers, thus creating opportunities for the enemy to sneak attack, and sometimes the enemy's bow and arrow throwing can also bring them a lot of casualties, after all, the musket can't shoot curves, but the bow and arrow can.

But even so, the penetration of the musket is still not comparable to the bow and arrow, although most of the Liao army is wearing leather armor, but not to mention leather armor, even the iron armor on the general's body can not block the penetration of the bullet, so as long as the musket can form a three-stage hit, the Liao army in front of it almost fell in rows, and it could not stop the footsteps of the Song army at all.

In the blink of an eye, the Liao army on this street finally collapsed, except for the Liao army who were killed or seriously wounded, the rest were almost scattered in a hurry, and Di Qing immediately commanded his men to move forward and quickly occupied this street.

Then Di Qing was about to command his subordinates to fight into another street, but at this moment, he suddenly saw a herald rushing over and shouted: "The general has an order, all the soldiers are stationed on the spot!" ”

"Garrison?" Di Qing was also stunned when he heard this military order, but then looked up at the already dark sky, and immediately understood, it seems that General Liu is worried that the Liao army will take advantage of the night to counterattack, so he does not plan to expand the territory anymore, after all, the Liao army is familiar with the terrain, if the other party counterattacks at night, they will suffer a big loss if they blindly expand.

Knowing what Liu Ping meant, Di Qing immediately ordered his subordinates to set up defenses, first of all, to demolish the houses on both sides, and then block the road with bricks and stones, after all, the Liao army is mainly cavalry, these bricks and stones can block the charge of the cavalry, and if the Liao soldiers get off the horse, it will be even less terrible.

With Liu Ping's order, the Song army, which was originally expanding outward, immediately stopped rushing and began to consolidate the area it had built, and the army outside the city also continued to march into the city to strengthen the defenses of various streets in the city.

Sure enough, on the night of the same day, Han Nanwang organized a large army to launch a counterattack on the Song army, wanting to drive the Song army out of the city by night, but the Song army had already prepared, although the Liao army broke through the defense of several streets, but most of the area was still guarded by the Song army, and the two sides killed from dark to dawn, and finally the Liao army was unwilling to retreat.

The failure of the Liao army's counterattack also represented that the Song army had completely gained a firm foothold in the city of Xijinfu, and then after a short rest, the Song army once again launched a fierce attack on other areas of the city, and another cruel offensive and defensive battle began to be staged in the city.
