"Changhai! Just how happy you are, how about it, you killed a few officials! ”

Liu Changhai turned around with a smile and found that it was Zhao Tianyou, the idol in everyone's hearts, and hurriedly knelt down on one knee and replied aloud.

"Report to General Zhao, the two artillery squads have blown up the heads of the two main generals of the Yuan soldiers, more than ten ordinary leaders. It's just that the shells are running out, and we ask the general to issue a few more ammunition, and we can't enjoy fighting here! ”

"It's good, as you have a lot of soldiers here, you can still fight like this, it's really good! The shells themselves were collected by their own people, and the cannons in several places were out of order, so they brought all the shells there. ”

Zhao Tianyou looked at the situation at the scene and knew that Liu Changhai had a flexible brain, and he had made a great contribution today, and the combat effectiveness of the firearms assigned and commanded by him was several times more lethal and threatening to the Yuan soldiers than at other nodes. The 20,000 Yuan soldiers gathered in the four directions of the second place had no way to threaten the defenders on the city wall at all, and the Loucha trebuchets had been destroyed, and in the absence of the threat of the Loucha archers, the thunderbolt cannons and Hongyi cannons were simply slaughtered like a roll call.

Looking at the building car and catapult that were not completely damaged, Zhao Tianyou glanced at Liu Changhai, this kid is really a talent. The platform of the building car was blown up, the tow bar of the catapult was broken, and the attack was on the vital point, and it was not wasted many shells to completely destroy it, anyway, it could not be used, and it was left in place to block the movement of the equipment behind it.

"Brothers, come out a few people, push two rack cars, and go to other nodes to shell!" As soon as Liu Changhai heard that there were shells to take, he happily arranged for someone to get them, and the firepower squads that followed him were not damaged, and even the casualties of the main force of the city guards were very low.

Because of the tense war, the guards of each node took care of the battle on their own ground, and no one inquired about the battle situation elsewhere, only idle people like Zhao Tianyou could patrol back and forth along the city wall.

After turning around a lot, Zhao Tianyou was completely relieved, and some nodes suffered heavy losses, and even let the Yuan soldiers attack the city wall, such as the node where Dong Lingfeng was stationed. However, the losses of the Yuan soldiers are also huge, and some places have lost the ability to attack, just like the place where Liu Changhai hit the general's head at the north city gate, the Yuan soldiers under the city have no command and no morale, and it is only a matter of time before they retreat.

Today's loss of cannons makes Zhao Tianyou feel distressed, but with the improvement of technology and the improvement of technology, after the technical problems of casting Hongyi cannons have been overcome, that is, the speed at which two cannons can be cast in minutes.

However, Zhao Tianyou didn't pay much attention to this kind of cannon, it was difficult to move, the rate of fire was low, and it was powerful and long-range, which was an excellent weapon for siege warfare. It can be realized in a passive defensive position, if you confront the Yuan soldiers and fight positional battles, the rate of fire is fast and the simple cannon is the king.

Of course, if you can create a machine gun that fires repeatedly, the term "Mongol cavalry dominates the world" can be removed, whether it is the long-range arm bow, the crossbow bed, and the standard longbow of the soldiers, it will not play a decisive role in the flexible tactics of the light and heavy cavalry of the Yuan soldiers.

The course of hundreds of years in history has proved that only after the advent of the machine gun with continuous ammunition can the fast mobile cavalry team really lose its value, that is, in the era of single-shot arquebuses, the cavalry still has enough advantages to crush the infantry.

The most primitive single-shot guns are not far from Zhao Tianyou's words, and if they spare time and energy, Lao Feng Tou and they will soon be able to cast a suitable iron pipe. The development and progress of gunpowder performance is also very fast, but smokeless gunpowder needs to cooperate with the chemical base, and for the time being, large-caliber black powder is still the main direction, so there is a big gap between the initial power of the gun and the artillery, and the fight on the battlefield still depends on cold weapons.

Therefore, the development direction of Zhao Tianyou is to realize the small-caliber rapid-fire gun as soon as possible, that is, the small-caliber Franc cannon filled in the back hall, which is the best weapon that can be realized by the current process. The Ming Dynasty Franc cannon is a developed version of the early European rear-loading gun, but it is different from the modern rear-loading gun. It has a front sight and a door in the rear, which can be aimed from the hole in the door, and has a gun carriage, which can be rotated up and down, left and right.

The abdomen is swollen, with a long mouth, and the outside of the gun body is wrapped in wood, and an iron hoop to prevent explosion is provided, and there are several sub-guns, which are loaded with ammunition and fired in turn into the long mouth of the abdomen. The advantage of this artillery is that it can be used to store ammunition in a pre-loaded gun, which does not need to be temporarily reloaded, and can be fired faster, and can effectively kill and damage enemy troops from a mile away when fighting cavalry.

The disadvantage is that the body barrel is shorter, and compared with the Hongyi cannon, it can not have a long range, according to the different calibers of the Franc cannon range of three or five hundred steps to several miles, when one mile away the highest hit rate. If Zhao Tianyou can equip his troops with Franc cannons, then he will have the ability to fight field battles with the Yuan soldiers, and there is no need to stick to the city like now, and passively wait for the Yuan soldiers to gather to attack.

The drawings and technical essentials have been handed over to Lao Fengtou, and it is estimated that there is now a small-scale experimental state, but it is still far from being on the battlefield. The key is the control of the accuracy of the barrel, and every time the gun is fired, there will be a huge kinetic energy, which is easy to cause deformation and barrel damage due to the gap between the gun and the barrel.

After all, the casting method is the simplest and roughest process, and Zhao Tianyou is too lazy to teach people many problems, so he still puts forward the requirements, so that these craftsmen can learn to think and know how to draw inferences from one case to solve the problem.

Zhao Tianyou followed the little gray gray, just like Meng Hao, when he came to Dong Lingfeng's jurisdiction, he couldn't bear to go anymore, looking at the wounded on his island, he couldn't ask for separate treatment. Because there were more wounded civilians in the city guards next to him, and some of them were even covering their wounds with their own hands, without bandaging them, Zhao Tianyou felt sorry for his soldiers, but how could he say it.

"General Zhao, Lao Dong is fortunate not to be dishonored, although he has suffered heavy casualties, but he didn't let the Yuan soldiers break the city from me, no matter what, it's worth it!" Dong Lingfeng looked at Zhao Tianyou, who came leisurely, and thought to himself that there must be no problem with the city defense everywhere, so Zhao Tianyou can be so relaxed, and the tight strings in his heart have also loosened a little.

Zhao Tianyou looked at the blood stains that had condensed a thick layer on the ground, and the corpses piled up on the side of the inner wall, and his heart trembled! There is no artillery, the personnel of the firearms squad have been killed and wounded, and the battle must have been extremely tragic in the early stage, and in the case of the loss of thunderbolts, they can only rely on assault rockets and building car buckets, can it not be tragic!

Lu Shikui looked up at the Song army on the city wall, still chasing the scattered Yuan soldiers under the city with bows and arrows, the burning building carts and catapults have lost their combat capabilities, how to fight next? The more than 1,000 new troops have been depleted, and the remaining remnants of the defeated army have no longer formed an effective formation, and ordering them to storm the city is tantamount to telling them to die directly.

Zhao Tianyou poked his head out of the arrow stomp and saw Lu Shikui looking up at a glance.
