"Here comes the plank!"

"Hurry up and get it done! Fast! ”

Huang Xu inspected the pits one by one, and constantly compared the drawings given to him by Ma Qiang, so that the sergeant could correct them.

"Huang Xu, how is the pit dugged?" Ma Qiang walked over with a sergeant carrying an explosives bag.

"Hui Minggong! The pit has been dug almost, please check it Minggong! ”

Ma Qiang stepped forward, looked at them one by one, took a dynamite bag and tried it, found that the size of the pit was appropriate, and nodded and said, "Okay!" Here, test fire, put a pot of black powder at the bottom, put a separator, and put a bag of explosives! ”

If it is a military fan of later generations who sees the dirt pit that Ma Qiang is making now, they will definitely exclaim, "No conscience cannon!" ”

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

In fact, the conscienceless cannon is not the first initiative of the Red Army in later generations, it has a prototype, that is, the Levens projectile invented by Britain during World War I, the Levins projectile gun is transformed and welded with a thick snorkel or a large oil drum, but he fires an oil drum filled with gasoline, which is used as an incendiary bomb, and the purpose is also to burn the German army in the tunnel, after all, Britain is not as lacking in heavy artillery as the Red Army.

The inventor of the unconscionable cannon, Nie Peizhang, was born as a military engineer in the Northeast and received a strict and systematic military education, so he was inspired by the Levins projectile cannon, and designed the unconscionable cannon according to the lack of artillery in the army at that time, and the situation of many battles.

And the reason why the pit is dug is because the conscienceless cannon must be buried in the soil before it can be used, and many film and television dramas in later generations will treat the conscienceless cannon as a gasoline barrel and put two wooden sticks to support it, that is too underestimate the power of thermal weapons, if you don't bury it in the soil, let the earth absorb this recoil, just wait for yourself to be blown up to the sky by this conscienceless thing.

In addition, it is worth mentioning that there is a premise for the emergence of no conscience cannon, that is, high gunpowder, black powder due to the low detonation rate, can not be made into an explosive package of appropriate weight, black powder to produce an explosive effect, its container must be a highly confined space, and the explosive package made of cotton or linen is difficult to achieve the ideal explosion conditions of black powder, even if it is barely reached, the wrapping layer will be thick, affecting the charge, if the charge is increased, it is too heavy, it is difficult to use the conscience cannon to throw in this way, so in the Zhenbei Army, the explosive package was real explosives, not gunpowder.

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

"It's compacted, the two fuses are lit together, be careful not to make a mistake about the length!"

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

"Tian Kai! As soon as the shelling begins, prepare for the attack! ”

"No!"

"Test firing!!"

With Ma Qiang's order, a fuse was ignited, first the black powder as the base medicine was ignited, only to hear a bang, after the black powder was ignited by the fuse, the rapid chemical reaction produced a large amount of nitrogen, carbon dioxide and other gases, the generation of these gases made the bottom pressure increase instantly, because the surrounding area is compacted land, these pressures can only rush to the explosives bag that only uses a wooden board as a separation board.

"Bang!"

An explosive bag fell directly to the gate of the camp, and more than a dozen sergeants with swords and shields watched the explosive bag fall to the ground, soft, and couldn't help but smile at each other, and one person stepped forward and kicked the explosive bag and said, "Is this a quilt?" The Zhenbei army saw that there was not enough quilt outside, so give it to us...."

Before the words fell, a huge explosion sounded, and the leg of the sergeant who kicked the explosive bag just now was directly blown into the sky, and then flew more than ten meters away before falling.

"The explosion point is appropriate, all the pit guns are ready, ignition!!"

"Bang!"

"Bang!"

There was a loud bang, and I saw ten explosives bags being blasted into the air, and then fell straight into the Wenchou military camp.

Then, the explosions came and went, and even the gate was directly blown into pieces of wood by an explosives bag.

Sergeant Wen Chou, who was guarding the southern camp, was stunned for a moment.

This is... Hell?

"Ignition! Put! ”

"Ignition! Put!! ”

A conscienceless cannon roared again, and saw that one by one explosive bags were thrown into the Yuan army camp, and the violent explosion and terrifying lethality made Yuan Shaojun, who was guarding the south gate, collapse directly.

Countless sergeants of the Yuan Army guarding the south gate turned their heads and ran, regardless of what weapons and shields, this is not a matter of courage or courage at all, in the face of the mysterious explosion and the huge flames that have no way to resist, they just want to hide far away.

But fortunately, the range of the unconscionable cannon is really limited, and the farthest projectile is only 200 meters, and it can also hit the middle of the South Camp.

This is also the reason why the conscienceless cannon disappeared in an instant like a meteor in military history, such a close range, but also requires earthwork, it is really chicken, as long as the other party has enough mortars, it can name the conscienceless cannon one by one.

But these shortcomings are almost all gone in this era, Tian Kaijun's soldiers looked at the explosion on the opposite side, and there was nothing that was not afraid, how strong can their armor be, and it can be stronger than the walled gate opposite? If this thing hits you, you won't even be able to find your bones.

But think about it again, this thing is on my side, so I'm still afraid of a fart, there is an enemy on the other side, this is obviously a military merit!

"It's okay, Tian Kai, come out!"

Tian Kai pulled out his horizontal knife with a bang, turned around and shouted, "Brothers! The general is on the side, the enemy is in front of him, the gate of the camp has been opened, and the marquis is worshipping the general, just today, kill!! ”

"Kill !!"

Tian Kaijun's soldiers roared in unison, scrambling to kill Wenchou Dazhai, this formation, Ma Qiang looked like a meal after high school.

Without the need for a sergeant to report, Wen Chou knew that something had happened in Nanying.

The familiar sound of the explosion announced that Ma Qiang was indeed on the Fu Mountain.

"Newspaper!! Checkmate! The southern camp was broken by the Zhenbei army, and the Zhenbei army used a strange weapon, which our army simply could not resist, and the southern camp had collapsed. ”

"How far is that weapon?"

"Not more than one hundred and fifty steps!"

"Did that move forward?"

"No way forward!"

Wen Chou knew in his heart, this thing is probably a weapon that is as difficult to move as throwing a car, and there are still fights.
