At this moment, General Hai Mutang's mind sounded a "boom"! Mongolian army artillery! They actually brought this thing into the Central Plains!... Behind the Mongolian army shield formation, one cannon was ready to fire under the shield wall.

These cannons are all about 1.5 meters long, but they are even thicker than the strong man's thighs.

Their gun mouths are about fifteen centimeters in diameter, and their gun bodies are all made of cast iron, with extremely thick outer walls.

Outside the cannon, there is also a unique numb touch of cast iron, and several ring-shaped reinforcement ribs are cast on it.

After these cannons were cast, they still retain their original gray-black.

Two rolling pin-sized handles were cast on the left and right of the cannon, which allowed soldiers to hold these handles and drag the cannon forward, or tie the rope to carry it.

After these heavy artillery were in place, they were immediately unloaded from the car.

Then they were mounted on cannon racks cut from heavy huge tree stumps.

Several iron chains rustled and tied to the iron handrail of the cannon, and then the iron chains were pressed to the ground. A group of soldiers waved large hammers and "ruffled" to pass through the iron chains, nailing them deeply into the soil, and firmly fixing the cannons in place like a tent.

The appearance of these artillery cannons is obvious in line with the usual style of the Mongols.

They are rough and solid, thick and rough, although not exquisite enough, but they are extremely solid.

After that, some scholars whose hair and eyes were very different from those of the Central Plains people came up.

While measuring the distance between the cannon and the city head, they constantly adjust the pitch of the cannon with a measuring angle ruler.

Next to them, several craftsmen were holding sledgehammers in their hands. According to the instructions of these scholars, they kept knocking on the wooden wedges between the cannons and the wooden piers of the cannons, so that the angle of the muzzle gradually reached the requirements.

The seventy artillery guns were adjusted, and then Mongolian artillery came up and filled gunpowder into the muzzle with its thick horns, and then stuffed heavy solid iron balls into the cannon.

As the iron ball made a rumbling rolling sound in the barrel, it finally hit the gunpowder at the bottom of the barrel, the firing of these artillery was also completed.

So, Torre ordered the wooden shield chariot blocking ahead to let go of the guns, and immediately issued an order for the entire army to assault!... General Hai Mutang felt a chill suddenly rise from his heart on the wall of Fancheng! After the Mongolian army suffered a great loss from Tongzhou's arms, they could not give up their research on gunpowder weapons.

So during these four years, the Mongolian soldiers continued to enrich and improve their gunpowder weapons.

One of the great advantages of the Mongols in studying this weapon is that they have skilled craftsmen on almost the entire Eurasian continent.

Among these people are countless exotic scholars who are good at geometry and even mechanics.

This allows them to rely on the world's largest and most complex craftsman scholars to solve it whenever they face technical bottlenecks.

After realizing the huge power of gunpowder weapons, Genghis Khan invested a lot of manpower and material resources in the development of this weapon.

Soon under his advocacy, the power of the artillery developed by the Mongols began to meet the requirements of actual combat.

Now in the Mongolian army sequence, there are two kinds of so-called artillery.

The first one is what I just saw, these iron cannons fixed to the ground with iron chains and large nails. They were cast with mud and cast iron.

After this gun is demolded, holes are drilled out behind the barrel to insert gunpowder fuzes.

At the same time, they also need to polish the inner wall of the barrel with manpower and simple machines.

This kind of artillery is not meticulous when casting, and the waste rate is extremely high.

Often after the cast iron cannon body is removed, cracks will be generated by uneven cooling of the cast iron cannon body, or large and small cast trachoma and pores, which are very common.

Even some iron cannons can be stuffed into a person's fist... Of course, these waste cannons cannot be used when cast, and they can only be smashed and recasted.

After about half of the scrap was eliminated, the remaining selection of qualified artillery castings was completed after a long period of polishing and drilling.

However, because Temujin now has huge manpower and material resources, he doesn't care about this waste at all.

After his experiments, he found that the power of this cannon was extremely powerful.

They could easily shoot a mile away from the 20-pound iron balls. These heavy iron balls could smash the opponent's city walls, gates and fortifications to pieces and splash around.

If it hits the middle of an orderly army, it will be enough to form a series of tragic killing.

So far, the Mongolian army has not developed a development bomb that can be used in actual combat.

They tried to produce gunpowder fuses on the flowering bullets, either exploded in the barrel in advance, or shut down the fire when they flew in the air after being fired.

Less than one-fifth of the flowering shells like this can successfully land and explode, but they often cause tragedies such as artillery damage and death.

Therefore, the Mongolian army has not equipped the flowering artillery shells that can explode, but the shotgun made from steel has a lot of reserves in their artillery units.

These shotguns are made of broken bad-quality artillery cast iron slag, as well as pebbles and gravel.

After one shot, it flew around and ran, with an astonishing lethality within a hundred meters.

This also gave the Mongolians an extremely strong sense of confidence and pride in their artillery.

So far, the Mongolian army has only used this artillery to conquer the strong city.

Because the Mongolian army was invincible at this time, it did not need any weapons to help them destroy the enemy troops of the other side.

And this time, Xiangyang and Fancheng are obviously such difficult-to-conquer strong cities.

So when Torre led his army to come, he also brought seventy extremely fierce artillery pieces, intending to use them to smash the enemy's walls when the siege was unfavorable.

...At the same time, the Mongolian army had another thing called artillery in their hands... In fact, this thing had nothing to do with artillery.

This kind of thing is an explosive weapon, cast by the Mongolian army into four shapes: barrel, round, jar, and bowl-shaped. In fact, it has the same effect as the Jin Dynasty's thunder.

However, the Mongolian army determined from the beginning that this kind of artillery was projected with a catapult. At this point, I wonder if they were inspired by the Jin army.

These so-called artillery, a little larger than a human head, are cast iron shells about one centimeter thick.
