The structure of a mine is much more complex than that of an artillery shell.

There are many types of mines, and what Liu Xuan knows are explosive mines, jump mines, and fragmentation mines.

These are anti-infantry mines, as well as anti-tank mines.

With the experience of making artillery shells, it was easier for Liu Xuan to make mines, and after having a simple structural drawing, the technical personnel of the Gangzhou City Military Factory were also very active in research and development, and soon invented and produced nearly a million mines of various types.

This was still made with all the effort, but the effect was ideal, and compared to the shells, the lethality was much increased.

In the south, a hundred miles away from the palace, there is a small city large enough to hold millions - the county and state seats.

At this time, the Nanshang army waved 3 million troops into the city, but to their surprise, the county and state city gates were wide open, looking inside, and there was no trace.

The Southern Shang Army was surprised, but he didn't think much about it, Yang Ba led the army and rushed in directly.

"Haha, this Nine Shadows Army is so cowardly as a mouse, and now they are afraid to lose the city." When they arrived in the city, the army quickly occupied the county and state city, searched around, and after making sure that there was really no one, they couldn't help but relax, in their minds, the Jiuyou army must have been afraid of them, and lost this inconspicuous small city in advance, ready to stick to the palace for the last struggle.

"Report to the general, the enemy army is coming from the north!" At this time, a herald shouted from the direction of Beicheng.

"Huh?" Yang Ba saw that the herald seemed to hesitate, and shouted angrily, "If you find anything, tell me quickly!" ”

"Yes, the enemy army is very small, only, nearly a hundred cavalry." The herald's face changed, and he hurriedly shouted.

As soon as these words came out, everyone was stunned, nearly a hundred cavalry? Could it be that only a hundred or so soldiers came to attack them?

Everyone immediately ran to the top of the city tower and looked down, and sure enough, in the distance, more than a hundred cavalry troops, fast horses, came in the procession, and there were two carriages in the ranks, each of which was equipped with a cannon.

Looking at this mere hundred soldiers, the Nanshang army was stunned for a long time, could it be that this is the army of Jiuyou? Such a poor team, could it be that they came to send them to death?

"Is it a deserter? Did you come to surrender? "This is the first reaction in the hearts of Yang Ba and the others, it stands to reason that if the Nine Shadows army comes to attack them, it is impossible to have only this little strength, more than a hundred people, two artillery, and it is not enough to plug the teeth, I believe that with Yang Ba's military strength, forty or fifty people can wipe out all this team.

For a while, the Southern Merchant Army had no idea of going out of the city to face the battle, but they wanted to see what tricks these more than 100 soldiers could play.

This scene, looking at it from a distance, there is a ridiculous and funny feeling, I saw that more than 100 soldiers from Jiuyou rushed to a few hundred meters below the city, stopped, and began to quickly dismount, load, aim, and debug, which seemed extremely orderly.

"MD, more than a hundred people, two cannons, just want to come and fight us, come here, go to two hundred soldiers, give me a head." On the city tower, seeing this scene, Yang Ba became more and more angry, this was clearly a provocation and contempt for them, and more than a hundred people began to fire cannons under the city so blatantly.

And at this moment, the artillery was lit below, and only two cannon shots were heard, and when the shells fell into the city, they only blew up two craters and did not cause much casualties.

When the soldiers below saw this scene, they quickly adjusted their gun positions and bombarded them with two more guns.

This time it finally worked, and it was amazing, when the shells fell into the city, suddenly, several more inexplicable bombardments rang out, several houses exploded, flames burned, and with the first explosion there was a second, a third, a fourth

To the surprise of the troops, the sound of the explosion continued, and more and more, more and more densely, almost endlessly, from one explosion area, to another explosion area, gradually covered, the Nanshang army fled in all directions, and some were directly blown off limbs on the spot.

On the city tower, Yang Ba and the others looked at the explosions in the city, their eyes widened in shock, they didn't know why, why there were so many explosions, there was no artillery outside, how could there be explosions, but where did they have time to think about these.

I saw that the entire county and state city were all burning, the explosions continued, the whole army of more than three million people seemed to be in the center of a cannonball, countless miserable cries for help sounded, countless scattered explosions surrounded them, dust and smoke everywhere, the whole city was constantly bombing, Yang Ba's three million army was hiding everywhere, but no matter where they hid, there were endless bombing sounds affecting them.

In the distance, the three million army of Jiuyou was killing this side, and they divided into four roads and ran towards the four sides of the city tower.

Yang Ba was stunned, he shouted desperately, but no one could hear his scream, the explosion never stopped, it lasted for half an hour, the whole town was in a sea of fire, as far as the eye could see, only countless corpses and bright red blood sprayed around the ground.

Liu Xuan buried nearly a million mines in the county, almost everywhere, these mines need leads, all of them are explosive mines, there are also a large number of gunpowder bags, and they are sprinkled with fire oil.

Only one mine detonates, and it burns on all sides, followed by the second, the third hundred thousand, and a million

And this city is equivalent to the cemetery of the Southern Shang Kingdom, a whole three million troops, in such a minefield, no matter how many lives there are, it is not enough to send.

Yang Ba didn't know when the explosion stopped, his mind was blank, he had never thought that such a thing would happen, and he had never seen such a terrible thing, in the blink of an eye, his army of three million was buried in a small city like this?

He couldn't accept this fact, and he couldn't believe it was true.

An enemy army has not yet been killed, but it has only arrived at an empty city, why in the blink of an eye, his army has disappeared like this.

Three million, not thirty thousand, he has been on the battlefield for so many years, how has he ever seen such an inexplicable war.

By the time the explosion subsided, the whole town had already become a ruin, a sea of blood, and even the dirt and dust on the ground were stained with blood red.

In the end, when Jiuyou surrounded the entire town with an army of three million, Yang Ba reacted, and looking at the surviving soldiers, there were less than 10,000 people who were able, hundreds of thousands of people were disabled, and all the others were buried in the ruins.

The entire army of three million was buried in the county and state city, in the hands of Yang Ba, and under the conspiracy of the Nine You Emperor.

Guan Zheng led the army into the city, and everywhere he went, he didn't leave a single living mouth, and all the soldiers were killed on the spot by the Jiuyou army, without mercy
