The return cannon is a catapult, a weapon brought back by the Mongols during their expedition to the West, and the cannon body is made of huge wood, and the joints are connected with metal parts. The gun carriage has a rotating gun shaft horizontally. The long rod fixed to the shaft is called "slightly" and acts as a lever.

The one with a wooden pole is called a single one, and the one that is tied together with multiple wooden poles is called a little, and the more a little number, the heavier and farther the stone projectile is thrown. One end of the cannon tip is tied with a leather socket to hold stone projectiles; The other end is tied with a cannon cable, and the rope is several zhang long. There are several small cannons, and there are more than 100 large cannons. Each rope is towed by 1-2 people. When throwing stone bullets, it is aimed and set by 1 person, and the cannons are dragged at the same time, and the other end is thrown up, and the stone bullets in the leather nest are thrown out by inertia and smashed on the city wall, the effect is very amazing, if the fire blanket and the carrion of the corpse enter the city, it can also cause fire and plague.

The Qing Dynasty's return artillery is a large cannon, the artillerymen push the huge artillery cart forward, occupy the firing position, the building car and the crash car behind are also preparing, and wait for the return artillery to suppress the fire and then take the opportunity to attack the city, of course, the tactical weapon such as the ladder is even less, and after the artillery bombardment collapses a section of the city wall, there are a large number of shield sharpeners waiting to rush into the city for hand-to-hand combat.

All this arrangement takes a little time.

The slaves were frightened, the people on the city wall threw rat traps, no longer shot at them, and some slaves, under the leadership of Duncan, ran to the nearby chain horse corpse to collect weapons and armor, and by the way helped the knights who did not die to relieve their pain, while the Qing people were preparing artillery, the slaves were also small armed, bows and arrows, chain mail, iron helmets, and long scimitars, all of which were the heads of the elite Qing Guards.

Yu Hualong on the city wall was very proud, the first use of the steam crossbow achieved such a great result had to make him a little fluttering, if he could repel the Qing Southern Expedition army, it would not be as simple as the Ministry of Works, maybe nine thousand years old and then reward a martial arts, not too big, the total army can be. Alas, the weapon designed by the old factory owner is powerful, thinking of that unbelievable old monster, Yu Hualong's heart tightened. "Come on, go and find out how the war is going on on the Lianfeng, a bunch of fools, it takes so long to attack a workshop!" There was a herald next to him to go down to the city to explore. While going downstairs, the herald slandered: Is Lian Feng an ordinary workshop, all of them are secret organs, and the workers are also extremely fierce, pulling out the finished and semi-finished products in the workshop to resist, that is, wearing them as iron cans to attack, it is difficult to say that it can be captured with 10,000 people in a year.

Zamuhe took advantage of the chaos to grab a horse, it was a chain horse rescued by splitting the chain, the skilled riding skills quickly made the healthy horse familiar with the new owner, Zamuhe untied the heavy vest, and hung the collected feather arrows on the saddle, Anthony and Duncan and others also stripped off the armor on the dead man and put it on a body, the long scimitar is very sharp, it is an excellent horse combat weapon, even Liu Ziguang also got two, the slave army after the impact of the chain of horses, and lost a thousand people, and now only more than 800 people are left in the open space near the drawbridge. Anyway, Yu Xiaolong is in the team, and he is not afraid of shooting arrows on the city tower.

The leader of the Hui artillery led the army and commanded everyone to install the gun mount in a position that could hit the city wall, he did not dare to approach any further, what force was used to shoot the javelin of the iron factory, it was fast and ruthless, it was simply terrible, the exposed artillerymen had no protection, and it would be troublesome if they were fired.

"Stone bombs!" The chief of staff ordered, the round stone ball weighing one hundred and fifty pounds was put into the leather pit, the artillerymen also pulled the gun rope, and eight huge return cannons awaited the order of His Majesty the Emperor himself.

The building car is also ready, the trajectory of the staggered return cannon is placed in front, the tall building car is about the same height as the city wall, and a number of soldiers can be hidden in the small carriage above, and when it is pushed to the edge of the city wall, the springboard can be released, and the city can go directly to the city, there are stairs in the building car, and the infantry below can continuously ascend to the city through the building car. The body is made of solid wood, covered with iron sheets on the outside, the chassis is heavy and not afraid of arrows, and there are a lot of wooden wheels under the chassis. It can be promoted, and with the return artillery, it is an excellent siege combination, how many fortified cities in Shandong Province have been conquered in this way, and this time the Liguo City will definitely be quickly conquered.

The shield-sharpeners hid behind the carts, and a large number of archers followed, and when they reached the city, they shot their bows and arrows on their backs, and the crash was an iron-hulled cart, in which hung a thick, pointed log, like a temple bell hammer, which was used to break open the city gates, and the soldiers hid in it to push the cart without being harmed by the arrows.

There are also a large number of soldiers carrying sacks and ladders, sacks filled with soil are used to fill the moat, so that the building cars and crash cars can approach the city wall, (Author: The moat is indeed a good thing) The ladder can be built directly on the moat as a bridge for infantry, and after crossing the river, you can also climb the city, killing two birds with one stone.

Qing Guo is really expensive to recruit this time. All the equipment and utensils are newly built, and they can't capture a Liguo City, and they won't dare to claim to be Qing people outside in the future.

Seeing the towering building car and the huge return cannon, Yu Hualong's face changed: "Huahu, what are the countermeasures?" Yu Huahu is an expert in defending the city, and his face is difficult at the moment: "Big brother, there is not much stock of arrows in the steam crossbow, this thing is consumed too quickly, there is a stock in the Lianfeng, but I can't take it out, I think the most I can do is kill his building car, the infantry and the crash is not terrible, it is that the return cannon, the distance is too far, we only have to be beaten, in case the city wall is smashed into a gap, their cavalry rushes in, this city will not be able to be saved." ”

"Then didn't we return the cannon and bombard them?" Yu Hualong does not give up.

"Hey, the old factory owner said that the thing was too backward and had never been built at all." Yu Huahu replied.

"Well, Huahu, you take it first, take care of your nephew in the city, I'll go back to the house and settle down." Yu Hualong, who knew that something was wrong, was ready to go back and load the soft family into the car.

As soon as Yu Hualong left the city, the return cannon launched an attack.

With the order of His Majesty the Emperor, the artillery staff waved the red flag, 200 gunners for each cannon, and a total of 1,600 gunners for eight cannons pulled the gun rope at the same time, and the tip of the cannon was quickly pulled up, and the stone bullets in the leather nest flew towards the city wall like meteors.

The return cannon was aimed at the same place, and the heavy stone bullets broke through the air with huge inertia and smashed on the city wall, and the hearts of the people inside the city wall were beating faster, and the iron guards in the hidden soldier cave also felt that the earth fell on their heads, and the stone bullets cracked, and obvious dents and cracks appeared on the city wall.

The return artillery was still firing, the building cars and crashing cars were also advancing under the infantry, and the earth-shattering shouts of killing were accompanied by the roar of stone bullets hitting the city walls, forming a majestic war sonata.

The pale face of the Qing Emperor smiled faintly, but the soldiers on the wall of the iron factory were frightened, and the people in the city were even more frightened, on the first day of the New Year, the dumplings had not had time to eat, they were all wearing brand new clothes for the New Year, they had just experienced the rebellion, they were frightened, and they had to face the return cannon of the Qing army, how could this be good, if the old factory owner was here, there must be a way, from the soldiers to the people, everyone thought so in their hearts.

Eight return cannons kept firing stone projectiles, the building car and the infantry had entered the firing range, Yu Huahu ordered the steam crossbow to counterattack, the shooting port on the city wall became lively again, the crossbowmen shot like crazy, replaced with a long javelin with burning arrows and shot out like locusts, smashed the iron sheet and drilled into the building car, pine oil ignited the inside of the building car, the Qing soldiers who were covered in fire were burned to the point of wah wow scream, fell from above, smashed on the soldiers of the cart, shot the javelin in the advance soldier cluster is even more overwhelming, even the shield is easily pierced, Dense blows, high-speed shooting, large areas of Qing infantry were slaughtered, and a few building cars also ignited a raging fire, which seemed to be useless.

Half of the gun trucks were replaced with clay pots filled with iron nails and lime, and the shells smashed on the crossbow firing ports, causing a choking lime mist, and the crossbowmen of the blackworks couldn't open their eyes, and the iron nails were fired indiscriminately, and many crossbowmen were injured, and if there happened to be a stone bullet hitting the firing port, it would be even worse, the steam crossbow was smashed, and the crossbowmen were also injured by the collapsed stones and bricks.

The ironworks' counterattack was suppressed, and even the javelins for crossbows were running out.

More than 800 slave troops did not dare to get too close to the city wall, for fear of being injured by the rubble, and the front was full of soldiers and horses of the Qing Kingdom. Big Brother"

Zamuhe looked at him, "No." ”

Anthony interjected: "If you can break through the tens of thousands of horses in front of you, and then break through the Qing cavalry behind you, you should have a glimmer of hope." The premise is, can you? ”

I can, but I can only guarantee that one person, with two women and a few brothers, it is definitely impossible. Liu Ziguang thought secretly, but he didn't say it, just said: "The infantry is not as scary as the chain horses, everyone is on the same page, and a few people who can escape are counted as a few people." ”

Liu Ziguang picked up a piece of chain mail for Peng Jingrong to put on, and threw another one to Peng Jingwei, Peng Jingwei pursed her mouth and said, "I also want you to help me put it on." Liu Ziguang replied viciously: "Do you think I am still your slave?" I want to wear it by oneself who wants to live! ”

Peng Jingwei twitched twice and wanted to cry but didn't dare to cry, and Yu Xiaolong next to her flattered: "Second Miss, I'll help you wear it." But she pushed her away, "Wear it yourself, wear it yourself." ”

If all the heavy armor of the Qing State chain horse cavalry is put on, they can't even walk, so they just put on the armor of the key parts of the upper body, put on the iron helmet, and hold the small round shield of the cavalry in their hands, and the only horses are gathered and let people with cavalry experience ride them.

The remnants of 800 slaves rushed towards tens of thousands of Qing infantry.

**************************************************************

Yu Hualong took a few guards with him and hurried to the mansion, walking on the empty road, suddenly a herald ran in front, it was the kid who was sent to inquire about the battle situation of the Lian Feng just now, the herald's helmet ran off, and he shouted breathlessly: "Lord Yu, the old ..... old factory owner...... The old factory owner came out, and those who went to attack the Lian Feng turned against the water and followed the old factory owner to kill here. ”

The worst fears came true. Yu Hualong felt a little dizzy and could barely stand.

As soon as the words ended, the roar of the machine sounded, and a black iron monster turned around the corner of the street, covered in steel plates and rivets, and all over the body, front, back, left and right, were turrets with movable iron covers. Under his feet are two rows of iron wheels, which make a screeching sound against the bluestone pavement.

On the iron monster in front of him, the upper body of an old man was exposed, and the old man with a white beard and white hair wore a soft leather hat on his head and held a large flag, on which was a black shield and a five-pointed star. Behind it was an identical iron monster, followed by an iron guard with a red belt on his head and an angry ironworks worker and his family with weapons.

Yu Hualong was so shocked that he sat on the ground.
