The sudden appearance of the cavalry made the Han army defending the city suspicious. Someone muttered, "Can cavalry also attack a city?" There were also people shouting: "Ammunition, quick, quick, get on ammunition!" At this time, most of the gun positions had just been fired, the gun body had just retreated, and the deputy gunner didn't care that the gun chamber was still hot, so he stretched the wet gun brush in, "Zila-Zila" A white mist was raised, and the black-faced ammunition hand stood next to him with a medicine bag in his arms, his red upper body was sweating profusely, and each gun commander was constantly shouting and urging: "Hurry-hurry-" There was a heavy and rapid breathing sound on each gun position.

Almost all the artillery of the Han army has switched to shotguns, because the range of shotguns is limited, at a distance of four or five hundred paces, the Liao cavalry did not need to dodge the shells at all, they were extremely fast, and while galloping on their horses, they lifted a round ball with a diameter of two feet from the side of the saddle. Almost instantly, the cavalry met the Liao infantry who were retreating. The palace tent army did not make any evasive moves, and rushed straight forward on their horses, until the routed soldiers cried and shouted in all directions. Fortunately, in just a few breaths, the cavalry had overtaken the rout and caught up with the advancing infantry formation.

The palace tent army was extremely skilled in horsemanship, and in such a chaotic and rugged battlefield, they were able to control their horses with only their legs, and their arms struggled to pick up the round balls, like a meteor hammer, and rushed towards the city wall. Accompanied by the roar from time to time, there were constantly shotguns whistling from the city, from time to time there were cavalry hit by shotguns, even men and horses fell down, most of the cavalry took advantage of the gap when most of the artillery was still loaded, in the shortest time rushed into the city wall within fifty paces.

"Put!" Xiao Ping shouted violently and threw the lit cigarette ball out first. In fact, most of the cavalrymen's minds were blank, their mouths were dry, and they could only follow the tactics they had agreed beforehand, and although they did not hear the officers' shouts, they threw the balls that had already reached the highest speed, and then struggled to tighten the reins, so that the horses could slow down at the shortest distance, and then turned around and fled desperately backwards.

Nearly a thousand balls had already ignited the lead, crossed countless parabolas, flew nearly fifty paces away with the speed of horses, and fell under the city wall, the fire rope was still burning, and after a while, the burning balls emitted thick and pungent smoke, and soon rose to the head of Nanshan.

More than 1,000 cavalry tent troops retreated like a tide. Almost at the same moment, the density of the city's artillery fire suddenly intensified, and the sound of "boom-" "boom-" "boom-" was incessant, and thousands of shotguns flew sideways from all directions, turning a range of 300 paces from the city into a slaughterhouse. After a short period of, this round of shelling was particularly ferocious, the shells did not have eyes, and in this bloody battlefield, there was no difference between high and low. Under the pursuit of artillery fire, Xiao Ping, the deputy general on duty, did not desperately urge the horse and war horse like other cavalrymen, but he was also like this galloping war horse, his heart was congested as if it was about to explode, and the shotgun flew past his ears with a whistling sound, his mouth was dry, and he couldn't think about anything else, so he could only lie down tightly on the horse's back to minimize his goal. Whether it was the retreating Liao cavalry or the hesitant infantry army, countless people were killed in the rain of shotguns.

"Your grandma's!" Zhou Yu scolded viciously, and the huge recoil of the cannon made the cannon body suddenly retreat. He stood beside the artillery, almost brushing past the regressing artillery, but he acted as if nothing had happened. Zhou Yu had thick gloves on his hands, he ignored the scorching heat of the gun, grabbed the muzzle of the gun a little straighter, and turned around and shouted: "Urine brush, hurry-hurry-" As soon as he got on the battlefield, this usually somewhat kind artillery commander became denied his relatives, and the gunners did not dare to slack off, and hurriedly sent the wet brush into the gun chamber, "Zi-" sounded, in the white mist steaming, Zhou Yu's smoky face was like a demon in hell.

Suddenly, his eyebrows furrowed, and he said strangely: "Damn, what is it?" The gunners followed his gaze, only to see puffs of black smoke rising from under the city wall, I don't know what method the Liao people used, this black smoke was extremely strong, and with the smell of sulfur and foul smell, soon blocked the vision, from the enemy's cannon eye, only saw a thick smoke. The Liao soldiers and horses loomed in the smoke and dust, but it was difficult to distinguish where the stragglers were and where the crowd was concentrated.

"Rush-" "Rush forward-" "Siege-"

"Ladder—" "Quick! Fast! "The ladder is set up, get on, give it to me!"

As the black smoke enveloped the city walls, the Liao army officers who were more than 100 miles away from the city wall disbanded their formations and commanded the soldiers to attack the city with shouts. In front of the battle, the thousand-commander, centurion, and ten-division commanders, one level pressed the first level, and whoever dared to turn around and retreat would immediately correct the law on the spot. Behind the formation, about four or five hundred paces away, there were countless palace tent troops who carried out military law and watched. The Liao soldiers rushed to the city wall like a tide, first put down the dirt bags they were carrying, and then gathered under the ladder, propped up their shields above their heads and on all sides, and climbed up the ladder one by one. Some Liao soldiers kept lighting smoking medicine balls under the city wall, making the billowing black smoke thicker and thicker, and some more than 100 people bent their bows and arrows with shields against their heads, and fired arrows dozens of steps away from the city wall. In the smoke, a cluster of arrows shot towards the city like flying locusts.

The gun emplacements at the head of the city were filled with smoke and dust, and the gunners covered their mouths and noses with handkerchiefs and handkerchiefs. However, the various artillery commanders were shouting: "His grandmother's! "I can't see anything clearly!"

"Up!" "Hurry up—" Because of his blurred vision, Zhang Wei didn't dare to hold it up, and repeatedly beckoned the people in the corridor to come out. At this time, more than a dozen ladders had been set up on the battlements. The firecrackers worked together to lift the fork rod and push the ladder outward, but they didn't know what the Liao army did under the ladder, and more than a dozen people couldn't push a ladder. Arrows rained down on the city, and although the firecrackers wore thick armor, there were always places where they were not well protected, and suddenly several people fell to the ground. Zhang Wei gritted his teeth, rushed to the battlement, and put the lit fire gun along the ladder, only to hear the sound of "boom", it seemed that someone had fallen from the ladder, but he couldn't see clearly through the thick black smoke.

"What can't you see clearly, my lord, what should I do?"

The cannon hole was not spacious, and the smoke rising from under the city wall made the vision extremely poor. For the gunners, it was already impossible to aim and shoot. Zhao Xingde took the iron cylinder that transmitted the sound, and ordered in a deep voice: "Don't aim!" Fire in the order of advance, the closest firing range, and the order of each enemy platform! The voice pipeline buried deep in the city wall transmitted the general's order to various enemy platforms, and the herald who had been guarding the side repeated loudly: "General Zhao's order, don't aim!" Close to the city wall, each enemy platform opens fire in order! With the issuance of this military order, the artillery commanders did not need to check the accuracy of the artillery themselves, but turned the artillery to the innermost part in the direction of the city wall, fixed it, and then personally guarded the side of the microphone.

"Zhenyuantai, fire in order!" Tong Yunjie said loudly. He commanded one of the six most important enemy platforms in Nanshan City, and a total of twenty heavy barrel cannons were arranged on the upper and lower floors, and with his order, these twenty iron barrel cannons opened fire in turn. "Pingliaotai, fire in order!" Liu Zhijian said in a deep voice. "Break the captive platform, fire in full speed and order!" Gao Su ordered. With the sound of "boom" and "boom", countless shotguns flew forward through the smoke. Because when building the city, all the gun emplacements were arranged to give full play to the side firepower as the main point, so when the cannon body turned to the closest to the city wall, the cannonballs fired almost swept forward along a trajectory parallel to the city wall, and the shotguns scattered inward even hit the city wall directly, and the Liao army who was climbing the ladder bore the brunt of the bullets and fell down one after another. In the smoke, the Liao army under the city wall fell like weeds swept by the autumn wind.

Nanshan Castle has a total of six enemy platforms, six attached forts, and gun emplacements on the concave city wall are also set up to clean the inner gun emplacements at the head of the city, and gun emplacements for the central giant cannon are also reserved for the future. There were more than 300 large and small barrel guns combined, and the design of these gun emplacements was painstakingly based on the principle of exerting side fire, so that each gun emplacement's frontal fire could cover other sections of the city wall, and if each battery fired sequentially at the same time, each section of the city wall was covered by side fire. More than 300 iron barrel cannons fired shotguns one after another, almost equal to nearly 10,000, or even tens of thousands of crossbowmen fired arrows with all their might, and the narrow area of the city wall of Nanshan City was filled with the rain of shotguns and blood mist.

The smoke deliberately released by the Liao army and the opening of the artillery caused the smoke to fill the air, and only the screams that sounded from time to time in the smoke could be heard, and the gunners were sweating profusely, only caring about loading ammunition as fast as possible, and then - fire!

At this time, the commanders of the enemy platforms were idle, Tong Yunjie stared at the cloud of smoke, and remembered a question that Zhao De had asked at the beginning, "If all the artillery positions are firing at full speed, how long will it take to kill all the people under the city wall?" He was slightly distracted, and suddenly there was a "boom", and a huge impact knocked him to the ground, "Damn, it's blown up!" Tong Yunjie's head was buzzing, he stood up with his wooden legs, and saw several gunners lying on the ground covered in blood, and the nearby gunners were looking at them. Tong Yunjie frowned, looked at those who were stunned, and shouted viciously: "Look at what!" If you don't want to die, hurry up and get to work, fire in order! ”

"Gun No. 3, fire!" The slightly glazed artillery commanders seemed to have been slapped in the face, and the gun emplacements that were not affected by the explosion seemed to be running as if the running machine suddenly stopped for a moment, and immediately started running at full speed again. Tong Yunjie nodded, pointed at the injured gunners, and waved his hand: "Send it down." Go and push the reserve guns up. "A few men lifted the wounded with all their hands, a few struggled to push the damaged iron cannon to the side, and some went to the ammunition room and pushed another gun cart out.
