Under Li Zhongyi's gaze, the two 6-pounder guns that broke forward were pushed to a distance of about 500 steps from the city gate hole, and then stopped advancing.

The length of a song step is about equivalent to a modern one. About 2 meters, that is, the artillery was pushed to a position of about 600 meters from the gate of the Daimyofu.

600 meters, which is definitely more than the maximum range of the unimproved Divine Arm Crossbow, so there is no need to worry at all.

There must be a bull crossbow in the city of the Daimyo's mansion, but Li Zhongyi couldn't figure it out for a while, why he hadn't seen the bull crossbow fight back so far?

However, Li Yongtang pushed the 6-pounder light cannon to the front, although there would be a risk of casualties, once it succeeded, the benefit was the greatest.

After all, compared with the methods of erecting ladders, piling up human lives, and robbing city towers, even if someone is killed by a bullbow, the loss cannot be too great!

It is impossible to go to war without dying, and if you can achieve a brilliant record of destroying the gates of the Daimyo Mansion with double-digit casualties, it is definitely a good deal no matter which aspect you calculate.

The 6-pounder gun, which belongs to the cavalry and infantry army, is a light gun, and the disadvantage is that the firing range is short and the power is small. There are many advantages, the most prominent of which is that it can be carried by cavalry for long-range raids.

The 12-pounder gun, which is powerful and has a long range, but the weight is too great, and it is difficult to achieve a high degree of maneuverability in terms of the current road conditions.

To put it bluntly, Li Zhongyi made a large number of 6-pounder guns, and the targets were mainly the Khitans with first-class mobility.

The Khitan was good at field warfare, but not good at defending or attacking cities, and Li Zhongyi brought a light 6-pounder cannon and then used flowering shells, which was enough to make the Khitans suffer.

As the saying goes, it is not difficult for those who know, but it is not difficult for those who are difficult!

As for the development of artillery, many times it is not that the technology does not meet the requirements, but that everyone is completely unaware of the tricks.

For example, from a smoothbore gun to a rifled gun, in fact, it is only necessary to add a few lines to the inner chamber of the clay mold when casting.

However, it still took hundreds of years to develop from the smoothbore gun to the era of the breech-loading rifled gun.

The core problem is that blindly climbing the technology tree requires trial and error everywhere, and the time cost must be paid.

Li Zhongyi is different, he is fully aware that the rifled rear-loading gun will definitely replace the breech-loading gun in the future.

"Boom ......"

"Boom ......"

More than a dozen 12-pounder guns roared in turn, and one of the thick projectiles hit the gate tower of the West Gate.

"Click......" The city gate tower collapsed in response, and the broken stones and broken trees splashed everywhere unscrupulously, and the defenders around the city gate tower who had no time to dodge were immediately affected.

"Ah...... My eyes ......"

"Yike...... My bowels are bleeding ......"

"Mother, it's killing me......"

Not long after Fu Yanqing left the city gate tower, he happened to be patrolling around the city wall, and happened to escape a catastrophe.

When Fu Yanqing saw the tragic situation near the city gate tower clearly, a great chill surged to his throat from the heart, what a powerful artillery!

I saw that the soldiers of the defenders near the city gate tower were lying down in a large area. Some people rolled everywhere, some people covered their stomachs that leaked out of their intestines and cried for help, some people were blinded by broken wood, and some people were simply hit in the face by broken tiles, and they died directly!

It was only at this moment that Fu Yanqing really realized that the artillery bombardment was powerful. He shook his body involuntarily, and his first reaction was to realize that the Daimyo's Mansion might not be able to hold it.

Just when the defenders of the city were in a state of panic, Li Yongtang commanded two 6-pounder guns and had already entered the predetermined firing position.

The closer to the city gate, the more accurate the trajectory of the launch trajectory will be, which is also the source of Li Yongtang's adventure forward.

Since Li Zhongyi gave the death order, Li Yongtang naturally did not dare to be negligent. Today, if he can't open the gate of the Daimyo's Mansion, tomorrow, he will really have to raise horses for Li Zhongyi.

The intelligence makes it clear that the defenders of the city not only have divine crossbows, but also powerful bull crossbows.

After reaching the designated position, Li Yongtang immediately ordered his artillery to erect thick wooden planks to cover the artillery team responsible for firing.

Li Zhongyi saw Li Yongtang's every move very clearly through the monocular. How to say it, in the face of possible casualties, he is inevitably a little worried.

However, as long as there is a war, there will inevitably be casualties, this is an unbreakable truth!

After seeing a lot of life and death, Li Zhongyi can only face the possible casualties with a normal heart, and the so-called success is definitely not a joke.

To Li Zhongyi's surprise, Li Yongtang divided the artillery team into two parts, and the main artillery team continued to bombard the city wall, in fact, it was equivalent to directly covering the actions of the 6-pounder artillery team in front of the breakthrough.

What is this called in the history of modern warfare? It's clearly fire cover!

Li Yongtang certainly did not realize the term "fire cover", but the decision he made happened to meet the basic requirements for attacking fortified positions in modern warfare.

To put it bluntly, under the continuous bombardment of the main artillery team, it is difficult for the defenders to fire calmly even if they have a crossbow.

Moreover, Li Zhongyi has not seen a bull crossbow shot in the city so far, and he has already figured it out, most of the bull crossbows in the city are too large to be deployed on the city wall.

The core of the historical alliance of the Yuanyuan, the Khitan commander Xiao Dalin, was shot to death was that the two armies set up camp in the wild, and the smooth development of the bullbow team was logical.

To put it bluntly, that is, Li Zhongyi is worried, this can be regarded as his wise man's thousand worries, and he is a hundred secrets.

People make mistakes, and in the years of war, when two armies are at war, it is often the one who makes fewer mistakes and the winner is the winner!

Since Li Yongtang has rushed forward, I am afraid that it will be difficult to command the coordination of the main artillery team, Li Zhongyi issued an order without hesitation: "Pass my military order, from now on, I will take over the command of the artillery team." ”

Li Zhongyi, who was in the command car, could see the whole picture of the entire battlefield clearly, and he was the person who best understood the principles of artillery in the Li family's army.

It was easier for Li Zhongyi to personally command the artillery team and cooperate with Li Yongtang's actions.

"Order the 12-pounder guns, all of them lower the muzzle of the guns by three scales, and as long as the artillery teams are ready, they will fire their guns accordingly and will not stop." Li Zhongyi was determined to adopt the harassment strategy of cannons, so that the Fu family army in the city would not care about it.

As long as the Fu family army in the city is in chaos, Li Yongtang, who is in front of the city, can aim at the city gate hole more calmly, which is the real idea of Li Zhongyi to take over the artillery team.

As for the death squad or death squad that may suddenly be killed in the city, Li Zhongyi is a master of sneak attack warfare, how could he be defenseless?
