However, if you look closely, you will find that these new "Salutes" are not the same as before, the muzzles are thicker, the entire gun body is longer and more complex, and there are many more parts, which are incomprehensible.

He saw that Pei Yuanshao was standing aside and watching, and he didn't do it himself, so he hurriedly walked over and asked him, "I said Lao Pei, what kind of novelty is this?" I look a little like the salute. ”

Pei Yuanshao smiled and answered for Zhao Yun, "That's right, it's the previous salute, but after several years of upgrading, the lord has given it a new name, called mortar, which is very consistent with its firing principle!" ”

"Mortar?" Zhao Yun thought it was quite interesting when he heard it, "I don't know how powerful it is?" Isn't the salute only used to fire fireworks? Mortars can be used for war? ”

"That's right, in the past, because of the production technology, the raw materials for the manufacture of gun barrels, etc., were not up to standard, so they could only be used for ceremonial flowers, but now the manufacturing process, materials, including the improved design are much more mature." Pei Yuanshao continued to explain.

"We are in the old camp in the clouds, and after a lot of experiments, the lord and Lord Ma Jun both think that it can be used in actual combat. And this mortar is extremely powerful, so the lord decided to try the effect with Xianbei people! Don't use it in fights between Han Chinese. ”

Zhao Yun nodded, Lu Bu has always advocated that weapons with great lethality should be used in foreign wars as much as possible, and that the war between the Han people can be captured and never slaughtered.

Soon these artillerymen (the soldiers who use mortars, naturally, should be called artillery), thirty mortars were assembled.

These mortars have a caliber of four inches and a barrel length of five feet, and after experiments, it has been found that the longer the barrel, the longer the range, but the relative power will also become smaller, so a balance is achieved.

In the end, Lu Bu's opinion was that the range should still be pursued, and it should be longer than the range of the repeater and the bed crossbow, so that the safety of the gunners would be guaranteed.

Of course, the gunners were also wearing the latest chain armor, which was improved and optimized after the introduction of this practical armor by the Central Army.

The Central Army Chain Armor is lighter in weight and has better protection, especially in close combat, and its defense against swords and spears is much better than that of the original.

The barrel of the mortar was cast from wrought iron and rolled from two layers of iron sheets, inside and outside.

Originally, smoothing the inner wall of the gun chamber with a steel drill was an extremely delicate and time-consuming task, but Ma Jun thought of a way to replace manpower with hydraulic drive.

This has brought about a leap in processing technology, which has greatly improved the effect and efficiency of pressing the iron sheet and milling the gun chamber, not only the iron sheet is smoother and tighter, but the speed of milling the gun chamber has also increased dozens of times, and it is smoother.

There is also a square iron plate under the barrel as a base, and the shells are made of cast iron.

The craftsmanship and appearance are very primitive, and the shell is filled with a powder pack, but the shell has a more advanced simple tail.

This is a suggestion put forward by Lu Bu, which can stabilize the flight attitude of the artillery shell in the air and improve the hit rate and range.

The mortar also had an original two-legged mount, which could only form a fixed angle, and the height could be adjusted briefly.

Lu Bu's original idea was, of course, to create a mortar that could be carried by a single soldier, but due to the limitations of the level of technology, production technology and material quality, it could only be a large weapon that could be assembled on the spot, cumbersome and even needed to be transported by pack horses.

However, in recent years, the progress of gunpowder experiments has not been small, the process of propellant and gunpowder has been improved, the smoke produced when the shell is fired has been greatly reduced, and the residue of powder residue in the gun chamber has also been greatly reduced.

In addition, the basic structure and components of the mortar such as the primer of the shell, the firing pin, and the original air-closed ring have already been prototyped.

Therefore, the mortar developed by Lu Bu and Ma Jun has the prototype of a modern mortar, which has appeared in this era across 1,700 years of time and space.

Its maximum firing range can already reach 200 zhang, and its effective firing range is 120 zhang.

The biggest difference between it and the previous Central Army's large-scale weapon, the stone thrower, is that the mortar relies on the power of gunpowder and the fragments of the shell to kill and wound the enemy, rather than relying on the weight of the stone projectile like the stone thrower.

However, the gunners, especially the gunners and sighters, were transferred from the trebuchet unit.

Because they had all learned indirect aiming, it was easier to get started with mortars, which often needed to curve fire at enemies hiding behind cover.

Even the officers and soldiers of the Central Army can't understand it, and the Xianbei people can't understand what those Han people are busy doing there?

Digging the soil, leveling the ground, and unpacking the wooden box, what are you doing there?

However, no matter what they were doing, out of instinct, the beggar neighbor thought it was better not to let it be done!

He looked at the Han army on the hillside in the distance, and the Han army was also arranged in a phalanx with brigades as a phalanx, so it was easy to calculate the approximate number of the Han army, and he could use both hands and feet!

At most, there are 70,000 or 80,000 troops, although they are all cavalry, but looking at the banner, there are four phalanxes of Huns, which should be their dog-legged servant army.

There are also the words on the banners of the two phalanxes, how do they look like Xianbei characters? There are also Xianbei people who come to help the abuse?

Their news is still relatively closed, and they don't know that the Xianbei Qianman tribe in central China has thrown themselves into the arms of the Han people and formed a Xianbei servant army.

Moreover, the military uniform of the Xianbei servant army is the same as the military uniform style of the Xiongnu servant army, but the color is different, and it is very close to the traditional military uniform of the Han army.

Unlike the traditional Xianbei cavalry, they all wear their own clothing and armor, which seems to be varied.

The Xianbei servants also changed into uniform uniforms and standard armor, as well as standard weapons in their hands.

They are not equipped with repeating crossbows yet, but each of them is equipped with a compound bow, which is much stronger than a hunting bow, which is also Zhao Yun's somewhat defensive mind.

The beggar ordered the two captains of his beggar department to lead their men to test it.

The two 10,000-strong troops were naturally not the elite of the tribe, only a small half of them wore leather armor or helmets, and most of them only had a hunting bow or a war knife in their hands.

Zhao Yun saw that the Xianbei people had dispatched 20,000 people to test it, so he first looked at Pei Yuanshao and his artillery.

Pei Yuanshao shook his head, "General Zilong, these hors d'oeuvres are not worth using our mortars!" ”

Zhao Yun thought about it as soon as he thought about it, so he turned to Zhao Zhao again, "General Zhao, your Xianbei army is dispatched, General Jin Rigang, your Hun army is dispatched two brigades!" ”

"Yes!" Recruit and Kim Hioka each led their men to meet a group of enemy troops.

Although both sides dispatched 20,000 teams, after engaging each other, the gap between the two sides was huge!

Although they are all using the traditional tactics of the nomads, first long-range, then hand-to-hand combat.

However, the compound bow of the Xianbei servant army obviously has a longer range than the hunting bow, and it has to shoot at least one more round of feather arrows than the opponent.

Moreover, these Xianbei servant troops are all selected from the Golden Family's royal court iron guards, and their combat effectiveness is already elite among the Xianbei people.

It was also equipped with the armor and spears of the Han army, which was even more powerful, and its combat effectiveness soared.

When recruiting and training them, the easiest way to improve their morale is to promise heavy rewards and publicize the military merit system of the Central Army to them.
