The explosion was very sudden and very loud, which startled the fierce Liu Heima.

"Boom!"

With the violent explosion, the stone bridge flew into the sky like a paper thing, and in the black smoke and firelight, the Han soldiers on the bridge burst everywhere with the stones.

The bridge is made of stone, and the craftsman skillfully built an arch with superb craftsmanship, and the explosives are probably buried at the highest point of the arch, which is the stress point of the whole bridge, and only the least amount of explosives is needed to achieve the best effect.

Therefore, the effect was very good, very good, a stone as big as a grinding disc flew out for more than ten zhang, and smashed the head of an unlucky soldier in front of Liu Heima's eyes.

The rain of blood in the sky stunned the Han soldiers who were fighting with the dense arrows in the river, and stopped their staggering steps in a daze, looking at the broken stones and human flesh falling from the sky in a daze, and they were stunned.

No wonder they were stunned, it was the first time in their short lives to witness such an earth-shattering scene.

The use of firearms in the Song Dynasty has a long history, but that is for the Song people, the northern nomads have not even lit firecrackers, not to mention this kind of large-scale use of gunpowder, in the eyes of many people, such an abrupt and unwarning explosion must have fallen from the sky.

The locust arrows behind the wooden wall are not terrible, they are shot by people, and everyone is the same in flesh and blood.

Can people fight with the sky? Can you fight with the gods?

Even the shaman on the grassland closest to the immortal heaven has a serious face and fear on his face when he talks about the heavenly thunder, looking left and right, for fear that he will be punished by heaven if he talks about God in vain.

The primitive threat was the most terrifying, although the Han soldiers did not believe in shamans, but they were also afraid of terrible things that they did not know, and when the falling stones began to fall on the top of people's heads, most of them shouted and turned around and ran.

The arrows scattered from behind the wooden wall chased after their backs.

Liu Chongjin's boots couldn't be pulled out, the mud was too deep and sticky, and he was helpless to use his strength to feed, and the last shot was ruthless, and with a vigorous pull, the feet came out, but the boots didn't come out.

In this way, with one bare foot, while scolding and brandishing a knife to order the people on the left and right not to retreat, he fled backwards with a deep foot and a shallow foot, and did not forget to put the shield behind him when he retreated, bowing his head in a hurry, and protecting his body.

In fact, he was secretly glad in his heart, glad that he didn't attack the stone bridge, it doesn't matter if he loses a boot, it's not worth losing his life like the buddy who attacked the stone bridge.

More than 2,000 Han soldiers, except for those who went out to die in the river, the rest were like the water of the ebbing tide, and they were defeated and returned.

The time before and after, but only a quarter of an hour.

The overseers standing on the shore were also at a loss by the explosion, and they didn't know whether to march or not in the face of the Han soldiers who returned without authorization, and they all looked back at Liu Heima.

Liu Heima's face was black, and his palms were almost out of the water.

Of course he knew what was going on, it was not a thunderbolt, but an explosion of a large amount of gunpowder.

When attacking Caizhou, the last capital of the Jin Kingdom, the people of the Jin Kingdom cried and fought while defending the city, and the blood covered the sun and black clouds destroyed the city, in order to resist the Mongolian army, they used a large number of firearms learned from the Song Kingdom, and Liu Heima had seen the power of firearms in the crackling sound.

A wooden frame mine thrown by the Jin people from the city killed more than 100 dead soldiers in front of Liu Heima.

I didn't expect that in the wilderness of the Hanshui River Valley, such a degree of gunpowder use could be seen.

It's not something that stragglers have.

Liu Heima knew that gunpowder was not only not easy to make, but also expensive to die, how could the mountain bandits and grass coars have such a thing.

Who is the army behind the wooden wall? can calm down and wait until his soldiers are close to a very close distance before attacking, and his calm demeanor is close to the veteran of a hundred battles.

"Boast of the trumpet, collect the troops!" Liu Heima squeezed out a few words from between his teeth, pulled out the horse and turned back.

The trumpeter next to him immediately felt out the horns that had been prepared, puffed out his cheeks, and blew out a low trumpet.

The sound of the trumpet made the overseers breathe a sigh of relief, and they were equally afraid in their hearts, if Liu Heima refused to retreat, it would be their turn to die in front of them.

What if the thunder falls again?

Wanyan Chengji stopped the bowstring that was a little hot, looked at the Han soldiers who were running farther and farther away from the one-foot-square hole, and smiled, happy and surprised in his heart.

He couldn't remember how many arrows he shot out in just a short period of time, anyway, in the basket that could hold a hundred long arrows around him, there were not many long arrows left, and most of these arrows hit the target.

The right arm is sore, there is a feeling of swelling, and the left arm is tingling, these are all the sequelae of a short-term burst of strength, there is nothing to fear, and it will be fine with a rest.

To his surprise, the arch bridge that had been blown up and the two protruding piles on the shore had been left, the bridge made of stone, the bridge that could not be smashed with a sledgehammer, was gone.

The large and small stones that rise and fall in the river are still vivid, and the corpses flowing with the waves are even more bloody to show the domineering of gunpowder.

In the past, the loyal and filial piety army was mainly cavalry and archery, and did not have much deep understanding of firearms, and felt that it was just a secondary thing to strengthen when defending the city.

Seeing that Liu Heima's brigade retreated, and the blood of the river flowed into the Han River, he jumped off the platform set up by the wooden wall, and ordered his subordinates to replace the people except the vigilant people After changing down and resting, he quickly let the people go out and clean up the arrows all over the ground, these arrows can be reused after recovery.

"There is no need to leave a living mouth." Wanyan Chenghei admonished, revealing a cruel sneer: "We don't take prisoners. ”

……

As soon as Liu Heima retreated, he withdrew for more than ten miles.

Counting the number of people, more than 2,000 people folded four or five hundred, of which only about a dozen died because the bridge was blown up, and the rest of the casualties were all because the army was killed by random arrows or drowned in the river when they fled.

Liu Heima's liver was shaking.

This is the elite of Lao Tzu, and he died so inexplicably, and he didn't even see the face of the enemy, what kind of strength is this!

"Drag these people down and cut them down!" He poured his anger on a few scouts, and angrily issued an order: "This birdman is not careful in his work, and he is inaccurate in finding out the news, which will cause my army to be frustrated and the soldiers to lose their lives, so he can't be left behind!" ”

The scout carried the pot and cried and was dragged away.

Liu Heima was still angry, sitting in the makeshift tent and thinking about it, recalling the battle situation just now, the more he thought about it, the more he felt that it was wrong, and the more he thought about it, the more frightened he became. Such a garrison, such a method of warfare, where is it like a bandit and a soldier living in a reckless place, it is clearly a strong force!

But who are they? The banner was obviously Jurchenwen, and Liu Heima recognized it, after all, in his early years, he was also a subject of the Jin State.

When he was depressed, it was getting late, and he was about to have dinner, but he saw the guards outside the door crawling in and shouting: "His Royal Highness Kublai Khan has arrived outside the camp!" ”
