"The planks are coming!"

"Hurry up and lay it down! Hurry up!"

Huang Xu inspected the pits one by one, constantly compared them with the drawings Ma Qiang gave him, and asked the sergeant to make corrections.

"Huang Xu, how is the digging of the pit going?" Ma Qiang came over with the sergeant carrying the explosive bag.

"Go back to Ming Gong! The pit is almost dug, please Ming Gong to inspect it!"

Ma Qiang stepped forward and looked at each one one by one. He also took an explosive bag and tried it. He found that the size of the pit was suitable. He nodded and said, "Okay! Come on, let's test fire a round and put a pot of black powder at the bottom."

Put an isolation board and an explosive pack!"

If future generations of military fans see the pit that Ma Qiang has made now, they will definitely exclaim, "You have no conscience!"

That's right, what Ma Qiang is doing now is a simple version of heartless cannon.

In fact, the heartless cannon was not the first creation of the Red Army in later generations. It had a prototype, which was the Levins projectile cannon invented by the British during World War I. The Levins projectile cannon was made by modifying and welding thick snorkels or large oil drums.

What he fired was an oil drum filled with gasoline, which was used as an incendiary bomb. The purpose was also to burn the German troops in the tunnel. After all, the British did not lack heavy artillery like the Red Army.

Nie Peizhang, the inventor of the Heartless Cannon, was a Northeastern Army engineer and received a strict and systematic military education. Therefore, he was inspired by the Levins projectile cannon and designed the Heartless Cannon based on the fact that the army at that time lacked artillery and fought many tough battles.

, this weapon has had a lot of soil work requirements from the beginning. If it were not for a tough battle, there would be no conditions to build such an artillery.

The reason for digging the hole is because the heartless cannon must be buried in the soil before it can be used. In many movies and TV dramas in later generations, the heartless cannon is just used as a gasoline barrel with two wooden sticks to support it. That is too small a thermal weapon.

If you don't bury it in the soil and let the earth absorb the recoil, you will be blown up to the sky by this heartless thing.

It is also worth mentioning that there is a prerequisite for the emergence of heartless guns, and that is strong gunpowder. Because the explosion speed of black powder is too low, it is impossible to make an explosive package of appropriate weight. For black powder to produce an explosive effect, its container must be

It is a highly confined space, and explosive bags made of cotton or linen are difficult to achieve the ideal explosion conditions of black powder. Even if they can barely achieve it, the wrapping layer will be unreasonably thick, affecting the amount of charge. If the charge is increased,

The amount of explosives was too heavy to be thrown by unscrupulous cannons. Therefore, in the Zhenbei Army, the explosive packets were real explosives, not gunpowder.

This is also the reason why Guo Yin used the trebuchet to throw grenades instead of explosive packets.

"Compacted, two fuses one.asxs., be careful not to get the wrong length!"

The fuse of the Zhenbei Army is divided into three layers. The inner core is granular black powder, the second layer is a gel waterproof layer, and the third layer is a wool thread reinforcement layer. Ordinary rain will not affect its continuous ignition at all.

"Tian Kai! Once the bombardment starts, prepare to attack immediately!"

"promise!"

"Test firing!!"

Following Ma Qiang's order, a fuse was lit. First, the black gunpowder used as the primer was ignited. Only a bang was heard. After the black gunpowder was ignited by the fuse, a rapid chemical reaction occurred.

The production of a large amount of nitrogen, carbon dioxide and other gases instantly increases the pressure on the bottom layer. Since it is surrounded by compacted land, the pressure can only rush towards the explosive package that uses only a piece of wood as an isolation board.

"Bang!"

An explosive package fell directly at the gate of the camp. More than a dozen sergeants holding swords and shields watched the explosive package fall softly on the ground. They couldn't help laughing at each other. One man stepped forward and kicked the explosive package with his foot.

He said, "Is this a quilt? The Zhenbei Army saw that there were not enough quilts outside, so give them to us..."

Before he finished speaking, there was a huge explosion, and the leg of the sergeant who kicked the explosive bag was blown directly into the sky, and then flew more than ten meters away before falling down.

"The explosion point is suitable, all the cannons are ready, start the fire!!"

"Bang!"

"Bang!"

With loud noises, ten explosive packets were blasted into the air, and then fell straight towards the Wenchou military camp.

Then, explosions occurred one after another, and even the gate of the village was blown into pieces by an explosive pack.

Sergeant Wen Chou who was guarding the south camp was stunned.

Is this... hell?

"Light the fire! Set it off!"

"Light the fire! Set it off!!"

The heartless cannons roared again, and explosive packets were thrown into Yuan Jun's camp. The violent explosions and terrifying lethality caused Yuan Shaojun who was guarding the south gate to collapse.

Countless Yuan Jun sergeants guarding the south gate turned around and ran away, regardless of weapons or shields. This was not a question of courage at all. Facing the mysterious explosions and the huge flames that had no way to resist, they just wanted to hide away.

.

But fortunately, the range of the heartless cannon is really limited. The furthest it can be thrown is only two hundred meters, and it can hit the middle of the south camp. Many sergeants who escaped here saw the Chinese army waiting for them and the soldiers who were hanging high.

Dozens of heads stood up and then stabilized their pace.

This is also the reason why the heartless cannons disappeared like meteors in military history. Such a short range and the need for soil work are really useless. As long as the opponent has enough mortars, the heartless cannons can be destroyed one by one.

Name your name to heaven.

But these shortcomings have almost disappeared in this era. The soldiers of Tian Kaijun looked at the explosion on the opposite side, and they were not afraid. How strong can their armor be? Can it be stronger than the village gate on the opposite side? What if this thing was

If it hits you, you won't be able to find any bones.

But when I think about it again, this thing belongs to me, so what am I afraid of? There are enemies on the other side. This is obviously a military achievement!

"That's it, Tian Kai, get out of the battle!"

Tian Kai pulled out his horizontal sword with a clang, turned around and shouted, "Brothers! The general is on the edge, the enemy is right in front of you, the gate of the camp has been opened, and you will be granted the title of marquis. Today is the day, kill!"

"kill!!!"

The soldiers of Tian Kaijun roared in unison and rushed towards Wenchou Dazhai to kill them. Ma Qiang looked at this formation as if they were having dinner after class in high school.

Wen Chou knew that something had happened in Nanying without the sergeant reporting it.

The familiar sound of explosions announced that Ma Qiang was indeed on Mount Fu.

"Report!! General! The South Camp was captured by the Zhenbei Army. The Zhenbei Army used a strange weapon. Our army was unable to resist it. The South Camp has collapsed."

"What's the range of that weapon?"

"No more than a hundred and fifty steps!"

"Did that ever move forward?"

"Not seen moving forward!"
