Those besieging the city would not have thought that the Ming army in the city had quietly changed its appearance and blood, and their equipment had also been updated.

Now, the Ming army in the city is fighting them with the most advanced firearms and the most powerful cavalry of this era, which is completely different from the previous group of people who only know how to cry and flee.

In addition to the terrifying Hongyi cannon, there was also a special force following Xiao Ruxun's side.

Among the 1,000 soldiers brought by Xiao Ruxun, there are 300 people who are Xiao Ruxun's personal guards, using rifled flintlock pistols, and the shooting accuracy and range are guaranteed.

After a long period of careful training and a large amount of ammunition feeding, the shooting ability of this team of flintlock soldiers dare not be said to be unique in the world, at least there is no firearms unit in the Ming Dynasty that can be compared with it.

In addition to a small number of rifled flintlock pistols in Xiao Ruxun's army, it is a smoothbore arquebus, and some generals suggested that Xiao Ruxun give up rifling and make more flintlock guns, because they felt that flintlock guns were more convenient to use, but after calculating an economic account, Xiao Ruxun decisively rejected their request.

In terms of ignition rate, the flintlock gun is not much higher than the arquebus, just a fire with an open flame and one without an open flame, one less shooting step, and it is finished like rain, and the flintlock ignition has high requirements for flint, and the cost of flint is higher than that of the current mature arquebus.

In terms of shooting efficiency, the smoothbore flintlock pistol is not necessarily much higher than the arquebus, and it is not accurate, and if there is no rifling and casting technology to improve the blessing, in the case of large-scale battles, the smoothbore flintlock gun is not significantly superior to the arquebus.

The real difference between the flintlock and the arquebus was the innovation of the musket infantry tactics, the arquebusier needed a lot of room for personal manipulation and could not form a tight line infantry phalanx, while the flintlock did not.

Flintlock pistols allowed soldiers to fit closer together, greatly increasing the density of firepower, thus influencing the innovation of firearms tactics.

As far as the current firearms workshop under Xiao Ruxun is concerned, there are still very few qualified spring steels that can be built, which is not enough to meet the requirements of the flint hair, and the pressure on all aspects of the cost is also very great.

Therefore, before the successful opening of European shipping routes, before the technology was innovated, the installation of flintlock guns was unrealistic, and could only be compensated by more arquebuses, and the meaning of the existence of these rifled flintlock guns was to set an example for the future, and instead of making smoothbore guns, it was better to make more advanced rifled guns in one step.

This group of flintlock gunners Xiao Ruxun was trained as snipers, and their purpose in going to the battlefield was not to shoot the other party's soldiers in a swarm, their target was conspicuous officers, and when the arquebusiers fired indiscriminately, Xiao Ruxun needed them to shoot accurately and specialize in hitting the opposing officer.

In several battles with pirates, including battles with the Spaniards and indigenous Filipinos, these flintlocks have made great contributions, and this time, Xiao Ruxun specially brought this group of treasure-like soldiers over, in order to open up foreign meat for these northern captives.

The northern captives below began to drive the captured soldiers to operate siege weapons, and the artillery pieces were put on the bed, crossbows, and trebuchets by thick arrows and stones, ready to strike at the Ming army on the city tower at any time.

This has happened a lot in the past half month.

Today, however, the situation has changed.

"Admiral, gunner ready!"

"Admiral, General Li is ready!"

Xiao Ruxun nodded, looked at the black and oppressive northern captives outside the city, and pointed his sword at them.

"Fire!!"

"Fire!!"

"Fire!!"

With the angry shouts of the herald officer, the first batch of ten Hongyi cannons began to roar, and a loud sound like a thunderbolt exploded in everyone's ears, and the huge roar surpassed the roar of all the artillery used before, and the strong sense of vibration shook the bodies of the soldiers on the city tower.

It was only at this time that Chai Guozhu knew why Xiao Ruxun asked them to block their ears to death.

It was only at this time that Li Rusong and Nurhachi knew why Xiao Ruxun had to cover the horses' ears with cloth.

People really can be deaf!

Horses will be frightened!

These guns are really different from the previous ones!

The thick smoke of gunpowder instantly filled the entire city tower, and the howling cold wind quickly blew them away, for the Ming army, the side effects of the Hongyi cannon ended here, and for the Beiyu below, the lethality of the Hongyi cannon had just begun.

They knew the range of the Franc guns, so the main forces were out of range of the Franc guns, and let the captured soldiers operate trebuchets and bed crossbows to get within the range of the Ming artillery.

Because bed crossbows and trebuchets could not match the range of the Furrang guns, they forced the captives to do so, and drove them with bows and arrows behind them.

If you don't go, you're dead, and if you go, you can still live, it's a simple choice.

As usual, the captured soldiers were desperate and ready to attack at the sound of orders, but unlike before, the Ming artillery rang out before them, and the sound was earth-shattering, and the terrifying sound frightened them all to the ground, and the piercing feeling made them involuntarily cover their ears.

They waited desperately and fearfully for death to come.

This time, however, death did not come as promised.

The aim point of the Hongyi cannon was not them, but the northern army formation behind them, which was a clear distance away, wrapped in thick smoke and carrying a solid projectile with a blazing temperature, roaring towards the northern captives.

The northern captives watched as smoke-laden objects flew past them, and then, frightened by the terrifying sound, fell to the ground, and then, the terrible object crashed to the ground, causing violent tremors and dust.

At this moment, they heard countless terrible screams, and some of them realized that they were sprayed with warm blood, and they screamed in horror, but the terrible sound never stopped.

After the solid bullet falls to the ground, it can bounce up and deliver a second and third blow to the dense infantry phalanx, until there are no soldiers in the path of their own advance or they cannot continue to jump forward.

Therefore, people often say that they will fight a bloody way, and it has been actually verified in these Hongyi cannons.

That is to rush all the way to kill, and kill a bloody hellish road stained with broken limbs, stumps, broken arms and internal organs.

The northern captives, who had never seen the terrifying range and lethality of the Hongyi cannon, formed a dense military formation, and such a dense military formation brought them a catastrophe of annihilation, a real catastrophe of annihilation.
