In the Jinling Lecture Hall, on the side of the teaching field, boxes of sky-shaking thunder were lifted out and placed in front of the queue of students. Tian Yi walked to the wooden box, took out one, and held it in his hand.

"Students, when you enter the martial arts hall, have any of you ever thought in your heart, I am skilled in bows and horses, proficient in swords, guns, sticks, and sticks, and there is nothing new in the martial arts hall?"

Tian Yi looked at the curious students and pointed to the earth-shattering thunder in his hand.

"Any idea what this is?"

"Instructor, this should be...... Earthquake thunder? ”

Wei Jin, who was from Lin'an City, was ignorant and knew something, so he blurted out a question.

"That's right, this is the Heaven-Shaking Thunder, which was created by the Principal himself."

Tian Yi pointed to the earth-shaking thunder, a serious one.

"The reason why the martial arts hall has set up an artillery section is that one is earth-shaking thunder, and the other is artillery. The reason why I asked you to listen carefully to the lectures and study them is to tell you that because of the appearance of earth-shaking thunder and artillery, the situation of the war has undergone earth-shaking changes. ”

The students all opened their eyes wide and looked at the earth-shattering thunder in the wooden box together.

In normal training, they cast iron lumps without gunpowder, and today is the first time they have seen a real earth-shattering thunder.

Solid wooden handle, the shell is fitted with a screw-iron cap, and the whole shape resembles a short wooden stick.

"Instructor Tian, you have opened everyone's eyes, what is the power of this earth-shattering thunder?"

Meng Hui asked Tian Yi loudly.

"All eyes wide, look at it!"

Tian Yi unscrewed the spiral iron cover, opened the fire fold, ignited the wire on the warhead, ran forward, counted 123 loudly in his mouth, and then threw the earth-shattering thunder in his hand forward.

The earth-shattering thunder flew in a parabola in the air and landed near an earthen wall where the target was buried, and a thunderous explosion sounded, filling the air with gunpowder smoke and dust, and shaking many of the students' faces pale.

"Come with me and have a look!"

Tian Yi led the students up, only to see that the earthen wall and the wooden planks of the target were inlaid with many explosive shrapnel, and some inches of wooden planks were broken through and shattered.

"Oh my boy, this is scary!"

Cao Youwan pulled a broken piece of iron from the wooden board, and his face turned pale. This guy can smash through a plank, and if he shoots at a person, won't it be bloody?

"If this is on the battlefield, hundreds, thousands of earth-shattering thunderbolts will be smashed together, not to mention the infantry, even the cavalry, thousands of horses, will also be blown up!"

Meng Heng's lips trembled, and she was shocked.

If there is this guy in the army, I don't know how many casualties will be saved. Don't talk about defending the city, it's enough for field battles.

No matter how powerful the cavalry of the Tatars and the Jin is, it is also made of meat. Can they withstand a shot of a piece of iron?

The stunned expressions of the students were in their eyes, Tian Yi's face was calm, and he was secretly proud in his heart.

Just the earth-shattering thunder, Zhao Hong had already convinced these students.

"Meng Hui, you come to drop the bomb!"

Zhao Hong had confessed that he would pay attention to Meng Heng, and Tian Yi would naturally take care of it.

"Yes, Instructor!"

In the envious eyes of the students, Meng Heng said loudly, he picked up a sky-shattering thunder and lit it, counted it three times, ran forward, and threw it out violently.

"The bomb throwing action is standard, very good!"

An explosion rang out, near the earthen wall target. Tian Yi applauded and gave a thumbs up appreciatively.

Bomb throwing, like spear art, is also a basic skill that the students of the martial arts hall must master, and the students must master it.

"Instructor Tian, the earth-shattering thunder is about to ignite, what if it rains?"

Some students thought a lot and asked curiously.

"When it rains, the earth-shaking thunder will not be used, and at this time, when the two armies meet and the brave wins, they will assassinate each other with pikemen and sword and shield hands. If the artillery carriage had cover, the artillery could provide limited assistance. ”

Since the bowstring is generally made of beef tendon or hemp rope mixed with silk, if it is soaked, it will lose its elasticity, so the rain is a constraint on both sides.

I heard that the bowstring of the Mongolian cavalry is not afraid of rain and snow, but I don't know if it's true or not?

"Instructor, although the earth-shaking thunder is ferocious, it is not much different from a bow and arrow in terms of range. If you shoot at a long distance, do you have to rely on artillery? ”

Meng Heng asked loudly, representing the voice of most of the students.

"Meng Hui is right! The artillery is a long-range weapon, but it is also a medium-range weapon, and the Sky-Shaking Thunder fights at close range. Firearms have tremendous lethality, and if they are well practiced, they can injure the opponent on a large scale, and at least reduce the unnecessary casualties by more than half. ”

Tian Yi waved his hand, and several large and small artillery pieces pushed up.

Three kinds of artillery were placed on the teaching ground: a small cannon with a fist size of 30 catties, a Franco-machine artillery gun of about 100 catties, and a field cannon of about 500 catties with a thick bowl on the gun truck.

All the trainees together, with surprise in their eyes, looked at the sun, these ghostly flashing front-loading smoothbore guns.

Just these few iron pipes are also a sharp weapon for killing people and destroying the enemy?

This is nothing more than a large assault gun, with an effective killing range of up to a dozen paces.

The effective range is one mile, and it also kills people by breaking armor. Isn't that a joke?

"The ignorant are fearless! It's all good! ”

Tian Yi secretly despised the ignorance of these rookies, and acted as a gunner himself, and under the watchful eyes of the trainees, he began to load the small cannon with gunpowder shotguns, adjusted the angle, and aimed at the target in front of him.

"Remember, a 30-pound small cannon charge is 7 taels, and 100 5-coin iron pellets are loaded in front, and then filled with 30 taels of lead pellets, with a range of 300 steps, which can break the iron armor."

The red-hot iron chisel in Tian Yi's hand lit the fire rope on the artillery fire door.

"Peng!"

The smoke of gunpowder was filled, and the iron and lead shots erupted thinly, and the targets hit in the distance were crooked and shattered.

"Let's go check it out."

Tian Yi waved his hand, and the students ran in the direction of the target.

Meng Heng and the students came back after watching the effect, and everyone was shocked.

If this is to be struck on a person, it must not be blurred by flesh and blood.

"Teach...... Officer, there are many people in the army...... Less small cannons? ”

A student's face was like earth, and he asked in a trembling voice.

If there is enough artillery and earth-shattering thunder, who is the opponent in the world? Self-protection is definitely more than enough.

"The headmaster said that about 50 people could be equipped with a small cannon, and horses and sergeants could carry it and use it anywhere. When fighting in the army, it can be used collectively, first to carry out artillery bombardment, then to drop bombs and shooters, and when the two armies fight in close combat, they will use pikemen to solve the problem. ”

The Song army was mostly infantry, so the army was equipped with a large number of crossbowmen. This is a major advantage of the Song army's long-range weapons, and it cannot be easily abandoned.

"This is a child and mother cannon, each weighing about 200 pounds, the mother gun is 3 feet long, and it is equipped with 6 child guns. There is a front sight and a rear door, which can be aimed from the hole of the door, and there is a gun carriage, which is loaded with ammunition in the sub-gun and fired in turn into the mouth of the abdomen. ”

After Tian Yi finished speaking, he loaded the 500 catties of field guns below, but the 7 catties of solid iron balls were loaded.

As for the Furlong gun, it's just a demonstration of how to load the gun.

"Peng!"

The iron ball tore through the air, flew in the air, and all the way past, rampage on the ground, bouncing and impacting, the earthen wall collapsed, the plank broke, and a small tree the thickness of an arm was directly broken.

Again, the shelling stunned the trainees.

"Remember, the solid iron ball breaks through the enemy by bouncing, and the 45-degree projectile has a range of up to two miles, destroying the withering and decaying, and is the most effective against the opponent's cavalry. If you set up a warship, you can destroy the opponent's warship from afar. Artillery and Skyquake Thunder are mixed and used collectively, and the effect is even greater. Let's imagine that hundreds of artillery pieces are fired together, coupled with the indiscriminate bombardment of earth-shattering thunder, the scene ......"

Tian Yi understated it, Meng Heng had palpitations, and his forehead was sweating.

"How many ...... Hundred Doors Fire ...... Cannon! ”

With firearms, the Great Song Dynasty had the foundation to resist the cavalry in the north.

Hundreds of artillery pieces take care of the long and medium distances, and there are crossbow arrows and earth-shattering thunder at close range, this kind of indiscriminate bombardment, even the iron cavalry of the north, I am afraid it will be difficult to destroy its edge.
