The stone bullets fired by the Liao army's artillery flew over the city from time to time, and although the accuracy of these stone bullets was low, some of them always fell in the city. Inside the city wall, the Han army's stone throwers were unmoved. Although they could not see the specific situation outside the city walls, as soon as the turtle shells of the Liao army came into range, the city would send a signal and they would immediately throw fire oil canisters.

Du Fujiao stared intently at the slowly moving turtle shell, and muttered, "Come on—come here—"

Suddenly, the turtle shell seemed to pause, shook in place a few times, and then stopped.

"Stop-" Wu Chun shouted angrily, but a few horses did not stop in time, and suddenly a burst of chaos formed in the crowded horses, and the riders strangled the horses around them, and it was easy for all the horses to be quiet. "Quick, quick! Set up the barrel cannon! Wu Chun hurriedly shouted. When he was directly hit by the city's head artillery for the first time, the wooden guard made three loud "bang" and "bang" sounds, and Wu Chun was so nervous that he almost fell to the ground. Although he has tried the strength of this giant shield, after all, the Liao State does not have the kind of long cannon that fires powerful round iron bullets, so whether the giant shield car can resist the shelling of the Han army, Wu Chun is also beating the drum in his heart. Fortunately, after a few "bangs", the giant shield car was not penetrated, and even because of the huge body, the shock caused by the shells was very small. The horses, accustomed to the close firing of artillery, moved forward slowly without any reaction, but the people in the shield cart exhaled with pale faces.

The artillery of the Han army was extremely violent, and in this quarter of an hour, the shell of the shield car "bang", "bang", "boom", and the ground sounded non-stop, and all kinds of round iron bullets and stone bullets smashed on the shield car as intensively as a summer rainstorm. From time to time, screams could be heard from all around, and it was the infantry phalanx that was under fire from the city's head. With the shield wagon's cover, the gunners scrambled to separate the gun carriage from the shield wagon, and then put the cannon's mount directly on the ground, otherwise the wooden components would not be able to withstand the huge recoil of the cannon fire.

"Why did you stop?"

Zhao Xingde frowned, he stared closely at the "turtle shell" that stopped and didn't move three hundred steps away, as if it was the protagonist of the Liao army's offensive. As soon as the "turtle shell" stopped, the other Liao military formations also stood still, as if waiting for something. Zhao Xingde's face was shrouded in a layer of haze, and suddenly, a wooden board in front of the turtle shell was opened, and a window was opened, and the black hole inside was not clear.

"It's not good, this is the giant cannon of the Liao people!"

Zhao Xingde suddenly drank out, and almost at the same time, there was a loud "boom", and a huge cobblestone bullet shot out of the "window". Immediately afterwards, this stone bullet weighing 600 catties with a huge speed, "bang" was smashed on the city wall, and suddenly the smoke and dust covered the sun, and the entire ground of Nanshan City felt shaken, and the soldiers closest to the bullet were almost unable to stand.

Because of the lack of casting technology, the Liao army's iron barrel cannon needs a lot of gunpowder every time it is fired, and the stone projectile almost fills the entire barrel, and in order to adapt to such a large charge, the bore wall of the iron barrel cannon is cast extremely thick. Although this is cumbersome, the power of the launch is enormous. With this stone bullet just now, Nanshan Castle seemed to have been shaken twice in a very short period of time, the first time was a loud noise when the cannon was fired, and the second time was the moment the city wall was hit.

The fort where Zhou Yu was located was closest to the city wall where he was shot, and he was almost shaken and fell. "The city wall is about to collapse-" This thought suddenly jumped out of Zhou Yu's mind, he looked out, fortunately, except for the smoke and dust, the city wall is there. Zhou Yu hurriedly rubbed his eyes, turned around and yelled at the gunner who was almost stunned.

"What are you doing in a daze, fuck me!"

The panicked Han gunners shouted almost simultaneously, and all sorts of shells doubled down on the damn turtle shell. However, the stupid and stupid guy seemed to be dull by nature, except for "snapping" to lower the cannon window baffle, and then squatted there, motionless and allowed the Han artillery fire to beat it, but no matter what kind of shells hit it, it would inevitably be bounced off, and at most it would bring up some sawdust.

"Why didn't you knock down the walls!"

Xiao Tachi was about to order the troops to rush to seize the city, and his face couldn't help but sink. The generals next to him didn't dare to pick up, Guo Baoyi. He explained: "Lord Tutong should be calm for the time being, this city is well built, and it will take a few more bombardments before it collapses. Xiao Tachi snorted, didn't say any more nonsense, and stared at the city wall viciously.

Zhao Xingde breathed a sigh of relief. Fortunately, the rammed earth walls of Nanshan Castle have withstood the test. He frowned and watched as the Han army's shells kept falling on the Liao army's giant cannon bunkers, but they couldn't penetrate it, but instead the shells that bounced off in all directions smashed into the nearby Liao army's formation, causing many casualties. The Liao army formation also held its breath, and seemed to be sure that the Nanshan city wall would inevitably be collapsed by artillery, and it stood motionless under the shells of the Han army at the head of the city.

"Leave the turtle shell alone and hit the phalanx next to you!" Zhao Xingde ordered in a deep voice.

The various artillery pieces of the Han army at the head of the city turned around and opened fire with all their might according to the Liao army's array within the firing range. This time, the artillery fire was more fierce than usual, solid iron bullets, rolling stone bullets, through the Liao army formation, inevitably brought pieces of flesh and wailing. At this moment, the cannon window of the turtle shell suddenly opened again.

"Watch out for the turtle shell!" "It's been fired again!" The Han army at the head of the city exclaimed.

With a "boom", near the 10,000-pound iron barrel cannon, the eardrums of the Liao army seemed to be about to burst, and they forgot to dodge the shells for a while. The 600 catties of stone bullets with great power smashed on the city wall of Nanshan again, because the firing position was extremely close, the landing point of this cannonball was not far from just now, and this short section of the city wall had already suffered two heavy blows from 600 catties of stone bullets. There was more smoke and dust at the head of the city, the dust stirred up by the heavy blows to the rammed earth walls. The smoke and dust cleared, and two large craters were blasted out of the city wall, and the originally densely rammed earth was falling down.

"Good!" This time, Xiao Tachi used the clairvoyant mirror to see the effect of the bombardment clearly, and excitedly ordered loudly, "Keep bombing for me!" ”

It's a pity that every time the Liao army's iron barrel cannon is launched, it has to be prepared for a long time. The giant shield car closed the gun window again, and put on a posture of lying down with a hammer on its head. This can make both sides in the city and the city and the city explode their lungs at the same time!

"Quick, quick-" Wu Chun in the shield car also saw the effect of the artillery bombardment too clearly, and he could only urge the gunners to hurry up and get to work. After each firing, there is a large amount of gunpowder residue left in the gun chamber, which requires the gunner to use a special big spoon to dig out, and at this time the gun muzzle is still emitting thick gunsmoke, and the gun chamber is extremely hot, not only is it easy to burn the gunner, but also can not be immediately cooled with cold water, otherwise you may blow up the chamber next time. Most of the people and animals in the giant shield car strangled their mouths and noses with strips of wet cloth, so many people were coughing loudly. More people's ears have been half-deaf by the sound of artillery in the enclosed space, and military orders must not only be shouted loudly to be heard, but also can be crossed.

"Not good!"

Zhao Xingde was alarmed, no matter how strong the Nanshan city wall was, it would not be able to support it if it continued to bombard a certain section. His gaze fell on the turtle shell, his eyebrows furrowed, and the thirty phalanxes of the Liao army were still stopped in the distance. Not far behind the turtle shell, there was obviously a palace tent cavalry army guarding the Han cavalry to go out of the city to counterattack. The Liao army would rather endure the heavy casualties of the artillery attack at the head of the city than let the Han army destroy their weapon of victory. The Han army in the city is only 3,000 people, and if you want to go out of the city to fight a bloody battle at any cost, it will be in the hands of the Liao army.

"Du blows the horn, and the sword and shield team goes to guard behind that section of the city wall." Zhao Xingde ordered in a deep voice, "Prepare earth bags and wood and stone on the thick surface of the city wall, and once the city wall collapses, the reserve team of the fire gunners will immediately rush up to seal the gap." "The Liao army's Tietong cannon is unstoppable, and the only advantage for the Han army is that the iron barrel cannon moves unchanged and is inconvenient to aim. If the bombardment continues like this, fools know that the Liao army must have chosen this section of the city wall as a breakthrough. Zhao Xingde hesitated for a moment, dispelling the idea of building a concave wall and a concave wall behind the city wall. Once there is a gap in the city wall, the Liao army's offensive will inevitably come like a tide. No matter how strong the concave surface is, it is not part of the original city defense system of Nanshan City, and there is still a gap in the near-perfect side-firing firepower arrangement of Nanshan City. And the concave Hao itself alone is not enough to resist the surging Liao army. If you want to defend Nanshan Castle, you must hold the line of the original city wall. After the city was broken, resistance and even street fighting led not to victory, but to death.

The military order was immediately executed, and the barracks behind that section of the city wall were immediately vacated, Du Fujiao led the sword and shield men, and Zhang Wei and other reserve firecrackers were stationed beside them. The Liao army's 600 catties of cannonballs, like the heavy fists of giants, smashed on this section of the city wall one by one. Behind the city walls, everyone's mood was a little worried. Even Du Fujiao, who usually has no uprightness, has a grim face, and only cares about directing the soldiers to pack a large pile of earth and stones, once the city wall collapses, they must use these things to plug the gap at the first time. In addition, some cloth bags are deliberately filled with only wood, because the wood is lighter, and it will be quicker to fill the gap with them in case it is too late. Just in case, the Han army reserves could not camp and sleep too close to this section of the wall.

"Brother Zhang, did you say that the city wall will collapse?" Huang Lun looked up at the flickering firelight outside the city from time to time, the night was falling, but the artillery bombardment of the Liao army did not stop, as if he had made up his mind, the city wall would not stop if it did not collapse.

"Bah, you crow's mouth!" Zhang Qi scolded irritably, just rubbing his pipe. At this time, everyone's hearts were heavy pretending to be something, and this huge shadow enveloped everyone, making everyone reluctant to mention it. This dreary and tense night passed slowly in the whistling wind and the sound of cannons.
