I saw several black shadows falling from the sky, and in the next instant, there were violent explosions one after another.

The explosion seemed to be louder than the cannon brought by Lomin, and this was what surprised Vytautas - he didn't know much about the specific principles and parameters of the artillery, but based on the information available, it could at least be deduced that it was not a very portable weapon, but more similar to a heavy siege engine.

How did such a thing get so close to the barracks without a sound?

You must know that although the Belan army did not plan to attack the coalition army at night, on the other hand, it was also prepared for the possibility of being attacked by the coalition army at night, after all, this was originally one of the classic tactics of defeating the strong with the weak.

There were many cavalry wandering within a radius of hundreds of meters outside the barracks, and there were also people staring at the barracks of the coalition forces, how could they miss something as big as artillery?

However, this is not artillery, but rockets falling from the sky.

It's not the kind of arrow that is set on fire, but the kind of rocket that you should have seen with your own eyes, and even set off with your own eyes, and it is the kind of rocket that uses gunpowder.

Luo Ming sent people with rockets to attack the Beran barracks at night, on the one hand, to harass them, and on the other hand, to test the rockets in actual combat.

Although rockets have some disadvantages compared to artillery, they also have some unique advantages:

It is not necessary to carry heavy artillery to launch a rocket, but to carry the rocket itself, and the rocket can also launch many in one breath in a short period of time, forming a greater momentum and higher fire density;

In addition, the rocket can consume the same weight of gunpowder under the premise of launching a larger amount of gunpowder, which is equivalent to a large grenade, Luo Ming has not yet been able to build a cannon that is enough to fire such a large-caliber grenade, and even if it is built, it will be so large that it cannot be brought to the battlefield at all - it probably takes several cows to drag it slowly, and it is a live target on the battlefield, and the enemy's mage throws spells, and it is impossible to move the cannon away in time to dodge.

If it was simply the kind of rocket that was set off during the Spring Festival, Luo Ming only took three days to make one, but that kind of rocket didn't fly accurately at all, and it was probably easier to hurt friendly soldiers when used on the battlefield, and it could fly less than 30 meters to reach grandma's house - it would be more accurate to throw a grenade directly.

This is where the inspiration for a rifled gun comes in handy - the shells of rifled guns are more accurate because the shells rotate along the rifling in the chamber, and their rotation makes the shells more stable.

So Luo Ming opened a small opening on the side of the rocket, which was used to release part of the gunpowder gas to push it to rotate, of course, there is a big mystery about where this opening is, Aya specially used the power of the demigod level to help calculate for a long time, and it was the best plan to be measured.

However, due to the limited precision of the processing process, this kind of rocket can only be made by hand, and it is impossible to achieve the most basic standardization, at best, it can only achieve a deviation of more than 50 meters at a distance of 500 meters.

Now Luo Ming can't make a bump fuse, that is, don't think about it for the time being, like the most common artillery style in movies in the previous life, a cannonball explodes the moment it hits the ground.

And the rocket itself also relies on the lead to explode at a timed basis, which is not necessarily accurate, sometimes it will explode in mid-air, and sometimes it will explode for several seconds or even more than ten seconds after landing.

With these two shortcomings, the rocket cannot be used on the regular battlefield for the time being, which is simply a waste of gunpowder, and whether or not it can hit the enemy is basically a matter of fate.

But at the moment, it has a good effect, and that is to use it to harass.

Eight hundred meters away, two soldiers strapped improvised launch brackets to their backs, turned over and walked away.

They didn't care whether the four rockets they had just launched could accurately hit the camp of the Beran army, nor how many people could be killed or wounded, as long as the rockets almost landed near the barracks of the Beran army, even if it had an effect.

After all, this kind of rocket can carry a lot of gunpowder, and if it explodes, it will at least sound many times more powerful than a second kick.

It was already night, and although the officers were still able to drink and have fun for a while, most of the soldiers, except for the night watchman, had already slept, and they must have been awakened in a cold sweat when they suddenly heard such an explosion.

In fact, two of the four rockets hit the open space, but one killed a soldier on night duty, and one exploded overhead in a tent, setting the tent on fire and injuring two soldiers.

Although this is not a big kill, it can make people's hearts panic, and the soldiers of this era do not seem to have a big heart that can sleep when they are likely to become the next victim with rockets.

Around that moment, the other man was getting ready in another direction, and when he saw the rocket streak across the sky, he flipped an hourglass over.

After about thirty minutes, the hourglass ran out, and he lit the fuses of the two rockets on the improvised stand.

The rocket slashed through two arcs, with a red glow of flames, and smashed into the camp of the Beran army.

At the same time, he put away the bracket and rode away quickly.

This time, the people of Belan were on guard, and when they saw the trajectory of the rocket, they immediately had a mage take action and cast a spell to intercept the rocket.

A rocket was hit by an electric arc and exploded directly in mid-air.

The other rocket was enveloped in a strong wind, and was redirected by the wind and flew farther away - however, it had only been flying for less than ten seconds, and as soon as it had left the barracks and reached the outside of the barracks, the fuse had already burned out and a large explosion occurred.

Naturally, no one was injured in these two explosions, but their sound was enough to wake up many of the Belan soldiers who had finally fallen asleep just now, and there was a commotion again.

There were even a few fools who woke up in a daze, thinking that the enemy was coming to rob the camp, and attacked their companions as enemy soldiers, almost killing them.

Although the Beran army is the side full of advantages, after all, it was blocked by the coalition forces today, and its own losses were a lot, and the soldiers were emotionally nervous, and if they were stimulated, of course, it was easy to have an accident.

Vytautas looked at this scene, his face pale.

A rocket that can cross a few hundred meters and hurt people will not be very cheap no matter how you think about it, and on average, if two of them can't kill a person, the coalition side will lose money completely.

But this account can't just be counted in this small piece.

Now, he had understood what the person who ordered the rocket attack was thinking - every now and then he pumped cold and released rockets here, just to make the whole Belan army nervous and watch out for the appearance of rockets at any time.
