"Yang Lang, what kind of magic weapon is this? Why is the mouth of the iron pipe facing heaven? Li Mochou squatted beside Yang Yifei and asked curiously.

Yang Yifei opened his mouth and came: "This magic weapon is called 'Heavenly Thunder Cannon', which can hit the cannonball into the sky, and then fall from the sky and fall to the target location, like thunder falling from the sky." ”

"It can reach seven miles at the farthest, and it can hit twenty zhang recently, the cannonball explodes, and the chickens and dogs are not left within a radius of five zhang, and nine deaths within eight zhang."

"Because of this, the cannonballs are shot into the sky and then fall, so the city wall is useless in front of this magic weapon, and it can even climb over the mountain to bombard the target on the other side of the mountain."

"This cannon is specially designed to siege the city, and it can wipe out the enemies on the city walls without having to go to the city."

The two of them suddenly couldn't help but get excited, there was such a magic weapon, so that it was a fortified fortress, and it could not provide protection for the Tartars.

Li Mochou asked again: "Then what kind of fame did you perform on your shoulders in the town before?" ”

Yang Yifei said: "That is called the 'soul chasing cannon', it is a direct shot, its biggest effect is to destroy the enemy's defense and large equipment, the Tartar return cannon is still very powerful, but in front of the soul chasing cannon, it can be dismantled with one shot." ”

"The distance that can exert the greatest power is about one mile, it can penetrate a six-foot thick stone wall, and the general city gate can be blown into pieces with just one shot, and the lethality of firing into the crowd is also good, of course, it is weaker than the heavenly thunder cannon, and it can only kill and injure people within a radius of three zhang."

Daniel Zhang was stunned: "That's also very terrible, it really deserves to be a soul chasing cannon, chasing soul and asking for souls, and it is difficult to escape." ”

Yang Yifei smiled and said, "However, using this magic weapon requires very complex calculations to control its accurate bombing targets. ”

"Now you don't need to know how to calculate for the time being, I will teach you slowly in the future, now you just need to learn how to fire a cannon."

"I have now preliminarily adjusted the landing point of the shell, you should pay attention to my movements, the cannon is very simple, the key is to pay attention to protect yourself, so as not to hurt yourself."

"After firing a shot, I'll make a slight adjustment to where the shell lands so that it falls where I want it to fall, and you stand back."

After Yang Yifei finished speaking, he took out a shell from the shell box, this box is 16 rounds, and the three guns are 48 rounds, which is more than enough to bombard the small camp of Tartars.

Li Mochou and Daniel Zhang stood behind Yang Yifei's side, watching his movements intently, but saw that he was just holding the shell with both hands and stuffing it into the cannon port, and then his hands loosened, but he tightly covered his ears and tilted his head back.

"Tom...... Rumble. ”

There was a muffled sound, and a column of smoke erupted from the muzzle of the cannon, and after less than a breath, I saw a large area of fire rising in the Tartar camp, and the roar like thunder came instantly, and the Tartar soldiers who were originally surrounded by three circles were suddenly in chaos.

Mortar shells are heated by the gunpowder gas produced by the combustion of the propellant and the air heated by its heat to create a pressure difference, which pushes the shell into the chamber and shoots it into the sky.

The strong pressure difference causes the air to vibrate violently and produce a sharp sound, and the shock wave generated by this pressure difference has the power to tear the eardrum, so the mortar must cover the ears when firing, and bow your head or crouch to prevent damage from the shock wave.

Although Li Mochou and Daniel Zhang did not understand these principles, they remembered Yang Yifei's movements.

This cannon did not fall in the center of a circle, as Yang Yifei hoped, but on the periphery of a circle, but because the Tartars stood too densely, this cannon killed more than 20 people, and four or five people were directly torn apart.

The Tartars were completely stunned, such an attack was incomprehensible to them, they only knew that this attack was coming from the sky, so they subconsciously ran to the camp tent, Yang Yifei smiled when he saw this scene.

He quickly fine-tuned the three cannons, and after adjusting them, he said to Li Mochou and Daniel Zhang: "Come on!" Let's do it together, pay attention to follow my movements, I kept firing without shouting to stop. ”

The two of them happily squatted in front of a cannon, and together with Yang Yifei, they stuffed the shells into the muzzle.

"Tom tom tom...... Boom Boom Boom ......"

The sound of cannons rang out one after another, and the thunderous explosion roared in all directions, and even the town several miles away could be heard clearly, and the inside of the Tartar camp was covered by patches of firelight.

There is no need to worry about uncorrected shells falling in the same spot, and the chances of two shells falling into the same crater are lower than the chance of being hit by lightning, so those large craters are usually the best natural bunker fortifications on the battlefield.

This is because in the process of firing the artillery, the recoil will make the mortar itself have a slight vibration, but don't underestimate this slightest vibration, as the so-called difference is a millimeter, a thousand miles.

Of course, the vibration of the mortar is not so exaggerated, but after each shot, the landing point of the next shot will definitely change slightly, which avoids the shells falling in the same position and wasting shells.

That slight displacement will cause the shells to form a connection of the killing radius, causing the effect of carpet bombing.

Yang Yifei's adjusted Zhuyuan was aimed at the camp tent area, and the three cannons were each aimed at three different areas, and the camp tent of the Tartars quickly fell into a sea of fire.

When some of the Tartars found it useless to hide in their tents, they rushed out of the tents and to the stables, intending to ride out of this hellish place.

Seeing this, Yang Yifei stopped firing the cannon, flipped his hand and took out a semi-automatic sniper rifle, and began to roll call the Tartar.

"Bang...... Bang...... Bang......"

After the incessant mortar bombardment, most of the Tartars had been killed and wounded, and in the chaos, only a few dozen people were scurrying around in the camp like headless flies.

The Tartars had no idea what had befallen them, and they didn't know how to dodge the shelling, so they just scurried around, which made it easier for them to die.

This would not have happened in later generations, because the soldiers knew that they had to find shelter when they were bombed, and when they heard the scream of the falling shells, they had already fallen down and quickly crawled to the bunker in a prostrate position, but where did these ancients know?

Besides, in the camps of this era, how can there be any shelters that can effectively defend against shelling? So the Tartar tragedy.

Some of the Tartars climbed under the carts carrying grain and grass to take refuge, but the carts were easily penetrated and blown up, and the fate of those hiding below can be imagined.

"Stop."

After Yang Yifei sniped more than a dozen people, he saw that the Tartars had already run out of the camp area covered by artillery fire and rushed to the stable, Yang Yifei stopped the two, quickly rushed to the two of them, put down the sniper rifle, turned the steering wheel of the machine, adjusted the shooting Zhu Yuan, and this time the trajectory was controlled about 20 meters outside the stable.

"Alright, let's go ahead!" Yang Yifei adjusted Zhu Yuan and continued to raise his sniper rifle to snipe those lone Tartar soldiers.

"Tom tom...... Boom ......"

Yang Yifei's time was mastered exquisitely, and when Li Mochou and Daniel Zhang began to fire artillery again, it happened to be the living Tartar riding on the war horse and rushing out, only to collide with a new round of bombardment.
