It happened to be in the gap between the third round of artillery shells of the Ming army, and the Song army on the front of the city seized this opportunity and began to fight back.

They shouted slogans and exhausted all their strength to force the three-bow crossbow, and then smashed it hard with a sledgehammer to fire the crossbow, and huge crossbow arrows roared out.

The catapult crew was similar. A group of people shouted loudly with their strength, pulled the ropes together and pulled them down desperately, throwing out the heavy stones or ignited firearms, allowing them to fly freely in the air.

The crossbow fired a large arrow, and the catapult threw out huge stones and ignited firearms. The counterattack of the Song army seemed to be huge.

With their brave counterattack, Zhou Benyuan also began to fulfill his promise and complete a shooting. He offered him five hundred cents directly and counted the money on the spot, and would never delay.

After getting the money, the soldiers immediately put it away, their faces flushed with excitement, and immediately began to prepare for the next shooting. Everyone was as happy as the children who received a large red envelope of New Year's money during the Chinese New Year.

Because they were happy, their movements were also very fast, and their efficiency was greatly improved. When the Ming army was preparing for shooting, they were ready to launch again.

Then they yelled at the same time and fired the big arrows and stones.

Then he looked at the little officials who were counting money with a burning look, staring at the money in their hands, with money in their eyes and minds full of money, and nothing else was left.

Because of this motivation, the Song army's counterattack began to become sharp, but this was of no use.

The catapult had no way to throw the stones and the lit fireballs to the position where the Ming army was, and fell directly on the way, which was meaningless.

The crossbow is quite interesting, and it flew quite far from above.

But the problem is that the crossbow cannot aim at all, and whether it can be hit depends entirely on luck. Therefore, its main purpose is to shoot the city wall and provide a foothold for the soldiers who are climbing the city. The secondary purpose is long-range strikes.

Seven or eight arrows more than two meters long shot out, and then they kept shifting their original direction in the air. In the end, they did approach the position of the Ming army, but the position had already reached grandma's house. Finally, they flew at an extremely low altitude and fell to the ground.

Not to mention it is meaningless, it can be considered a waste of effort.

However, this is of some significance to the Ming army.

Through this shooting, the Ming army discovered the long-range firepower point of the Song army and found that the Song army on the top of the city was launching a counterattack. So the artillery team's observation hand held the clairvoyance and kept observing, while conducting simple mathematical calculations.

The artillery location is about 150 feet away from the walls of Fancheng...

The walls of Fancheng are about two meters high...

The walls of the city wall are about two meters wide...

The general's gun muzzle was raised from the horizontal shot and raised the muzzle at once increased the range...

In order to increase the accuracy of artillery shooting and to make the mathematical model of ballistic calculation more accurate, Su Yonglin introduced the concepts of angle and coordinate system. While imparting knowledge of coordinate system to the police officers, he also made a protractor by himself.

He used mathematical calculation methods that he could still remember to describe the existence of angles and passed on this concept to the stakeholders in the court, and then the stakeholders brought the angle and coordinate systems into the mathematical calculation model of artillery shooting.

The planners were so excited that they had found the mystery of artillery shooting.

They calculated and recorded some columns of data launched by artillery at the experimental base in Zhongdu.

A lot of calculations have also been made about the relationship between the weight of the fired gunpowder and the range of the shell.

A lot of calculations were also made to change the range caused by the muzzle elevation and recorded.

The relevant data of the entire artillery launch were summarized and recorded into a set of tables. After a large number of test firing and data recording and calculation, as well as the introduction of the concept of gate and sightseeing, the Ming army artillery team gradually had a scientific concept of artillery launch.

Even the weight of the fired gunpowder required for different types of artillery and shells of different weights was calculated. Therefore, the fired gunpowder of the Ming army artillery was fixedly equipped in a professional workshop, weighed by a dedicated person, and minimized errors and sent directly to the gun team.

The gun team also set up professional observers, holding clairvoyances, and will calculate various data before the war, make rough estimates, and guide fire, which greatly improves the shooting accuracy of the artillery.

After each launch, they will also observe the shooting results, and then adjust the launch position and launch angle of the next launch.

The rest of the gun team is responsible for adjusting the gun to the best position the observer believes and then firing.

After this series of processes, it can be said that it is quite scientific and has reached the peak of the scientific process of bore gun launch in the smoothbore era.

At the beginning, even the artillery craftsmen who made artillery only thought that the gunner was a military that required courage, and that as long as they had the courage, they could be gunners.

But later everyone discovered that the gunner needed not only courage, but also mathematical knowledge.

People who don’t understand mathematics cannot be a good gunner. Even a member of the gun team responsible for igniting and firing drugs must have a certain reserve of mathematical knowledge. Otherwise, what should I do if the observer suddenly gets injured and cannot guide the fire?

In fact, the training of Ming army gunners is developing in this direction.

The strategy of cultivating gunners in the Ming army has advanced to the point where a relatively systematic mathematical education is required for gunners. All the currently known mathematical knowledge about artillery must be taught to allow gunners to master them and also take exams.

If you fail the exam, you cannot become a gunner.

The results of spending a lot of effort and price training of gunners are also obvious.

On the current Xiangfan battlefield, after each launch, the professional observers of the artillery team will slightly adjust the shooting angle and shooting position through observation and calculation, so that the next shooting can more accurately destroy the Song army city wall.

When the Song army counterattacked on the city wall, the observers could also adjust the shooting angle and orientation by calculating and attacking the bed crossbows and catapults that could also strike on the city wall.

It’s not that it can be really accurate, but that it can be said that within the effective range, the shooting accuracy should be improved as much as possible.

The introduction of mathematical concepts gave the Ming army artillery team a scientific concept that transcends the times. For artillery launches, they no longer count wherever they hit, but do their best to control the direction of artillery launches and increase the war value of each shell.

The artillery group armed with such a concept is indeed a nightmare for a fixed city.

So the third round of artillery began.

Amid the roar, the commanders of the Song army were horrified to find that the Ming army's artillery shells were bombarding the city floor with a more accurate accuracy, causing a terrible blow to the crossbow unit and the catapult unit that were shooting on the city floor.

An iron bullet suddenly fell, smashing the catapult and the crossbow, and also smashing the Song army soldiers into meat. Blood and blood splattered everywhere on the city floor. The soldiers howled in horror and ran around to find cover.

Some of them were so scared that they were in a panic that they climbed over the city wall and fell down from the seven or eight meters high city tower, and died immediately.

The city tower was in chaos, and many Song soldiers were killed and shocked. The city tower was in chaos, and there was no chance of seeing a few lucky people who could still stand.

This round of artillery attacks the Song army very much. Zhou Benyuan continued to order the increase in rewards afterwards. As long as he dared to go up and fight back, he would directly reward money.

The amount of reward increased from 500 cents to 1,000 cents, which was a permanent sum, but no one was willing to go up. Zhou Benyuan was anxious and ignored nothing and immediately started killing.

His current image is like a machete in one hand and holding copper coins in the other hand, cutting his head and scattering coins.

"If you go up the city tower and send arrows, you will be rewarded! If you retreat and avoid the battle, you will not dare to go to the former, you will be killed!"

He ordered his personal soldiers to kill more than 30 collapsed deserters, and then moved out boxes of copper coins, forcibly forcing the rest of the Song army to go up to the city tower to launch a counterattack.

The Song soldiers could only cry while going up to the city tower and were forced to move towards their own destiny.

The Song soldiers under the city tower were not easy either, because the present of others was their future, and they were just not yet on their turn.

The grief and fear spread throughout the army.

But they were powerless to do anything about it, because they were just big-headed soldiers, the lowest-ranking people, and the ones who forced them were generals, officers, and those who could determine their life and death.
