Liu Heima and his team were about to cross the Jishui River when an explosion occurred.

I have to say that he is very lucky. If he ran a little faster or had a little longer fuse, Liu Heima would just stand on the gunpowder jar.

The gunpowder buried under the wooden wall was all that Changsun Hong left here, leaving no one or two reserves, and was given to Wanyan Chengsi, who buried them all under the wooden wall.

The quantity is about a few hundred kilograms.

Basically, all the gunpowder that Sichuan Military Arts Institute can produce during this period is here. If Wang Kui, who was far away in Chengdu, knew that Changsun Hong was using precious gunpowder so wastefully by his prodigal son, he would definitely jump.

The gunpowder of the Southern Song Dynasty was actually very powerful. Although it was much inferior to the various strong explosives gradually developed in later generations, it was enough in this era.

This shows that the strong stone bridge that was blown up yesterday. If the bridge had not been in this disaster, it would have been no problem to stand proudly on Jishui for more than a hundred years. The craftsmen in the Song Dynasty were so solid.

So although Liu Heima has not yet entered the water and is about ten feet away from the wooden wall, when the explosion occurred, he was still shocked by the shock wave and fell into the mud inside. His heavy armor was heavy and thick, making his eardrums buzzing and fluttering in the mud for a long time.

It was also his fault that he was in trouble. A place where explosives were buried was right in front of him. The violent explosion blew up the wooden wall so that countless pieces of wood were flying out of it. Perhaps gunpowder was buried under the wooden stakes. In fact, it was either buried or placed there. When it exploded, the wooden fence jumped up with the flames and black smoke, and then collapsed into many pieces and flew in all directions.

Gunpowder is placed in four or five places, and is distributed evenly according to the principle of putting it at every distance, covering the entire wooden wall as much as possible. Therefore, explosions occur at the same time in so many places, and the scene is spectacular.

Few people have seen such a scene between the Han soldiers and the Mongolians behind them.

"Boom boom boom!"

The loud noises like landslides rang one after another in a few seconds, which was even more terrifying than yesterday's explosion.

The entire wooden wall was instantly swallowed by black smoke, and a large stream of smoke and dust enveloped the banks of Jishui River. The Han soldiers in it shouted shrillly, whether they were injured by the bomb or not, they were shouting in panic.

After a while, Liu Heima was pulled up by the people on both sides. His personal soldiers were frightened and waited for a while before they found that the main general was struggling in the mud like a loach, and then they rescued him.

Liu Heima's face was covered with mud and water. He wiped a handful of mud covering his eyes and looked around in a daze. He grabbed the knife in his hand tightly and did not dare to let go. He shouted several times: "What's the matter? What's the matter?" Then he gradually woke up.

"Sir, it's the Song people's firearm!" Someone roared in his ear like a drum, pointing desperately at the black smoke in front of him: "The Song people's firearm exploded!"

"Ah?!" Liu Heima felt like a mosquito was buzzing, and she let out a whistle. After her subordinates repeated it, they understood: "It exploded?"

Cold sweat broke out from behind, and Liu Heima felt a little weak under his feet. He estimated that if he had just gotten so fast, then there would be a part of his own among the corpses flying in the sky at this moment.

He took a few steps back and stood on the river bank, a little further away from the scene of the broken explosion of the wooden wall, held the somewhat tilted helmet, and set his mind on: "Don't rush over first, just in case the Song people have any tricks!"

Left and left and right agreed and quickly passed his orders. The crowded Han soldiers on the shore immediately stopped and looked at the other side in a wandering manner.

The Han soldiers who did not cross the river were safe, but the Han soldiers who crossed the river were panicked.

Of course, the people near the wooden wall are the worst. The dead and wounded, and the people who happened to be between the two explosion sites were also frightened and were shocked like a fool, running around in the spot or running around in scattered areas.

A little further away, the Han soldiers who were chasing the Jurchen soldiers and walked away were so shocked that they were at a loss that they stopped, wondering if they should continue chasing.

The smoke in the air rose rapidly and soared into the sky.

Although Kublai Khan was far away from the wooden wall, the horse under his crotch was still frightened by the shocking earth. He kept shaking the reins and touching his neck to calm it down.

"Is that the Song people's firearm?" Kublai Khan, who saw the power of gunpowder for the first time, his eyes wide open, his face full of incredibleness, his face as big as a silver basin, turned pale for the first time. He instinctively grabbed the round shield hanging on the side of the saddle and asked in surprise: "What kind of firearm is so powerful?"

The Han aide Zhao Bi followed him and immediately replied: "Go back to Your Highness, this is the gunpowder of the Song people. It must have been buried behind the wooden walls for a long time. Seeing that I could not resist the attack of our army, I lit it to kill our army. I had seen the Jin people using this when I was in my hometown in Yunzhong."

"Gunpowder?" Kublai Khan held the round shield in front of him and asked in surprise: "What does it look like?"

"It is a powder-like thing, made of saltpeter and other substances. It is widely used in the Song army. The Jin people and the Song people have been in contact with each other for a hundred years and have also been brought in. Back then, our army destroyed the Jin people, and the Jin people also used it. However, this thing will be reduced by one point once, and it will not cause a series of problems when it is used in one place. After it is blown up just now, there will be no explosions." Zhao Bi comforted him.

When the Mongolian destroyed the Jin Dynasty, Kublai Khan was only sixteen years old. He was following his elder brother Mongke. He was leading his uncle Badu to fight westward to Europe. He was far away in the cold Ukraine and looked for the bad luck of the Russians. The West did not have the skillful use of firearms as skilled as the Song Dynasty. Kublai Khan did not open his eyes. At this moment, he saw the power of a large-scale gunpowder explosion for the first time, and he was shocked and scared.

Zhao Bi's words made his heart a little more shocked, but the shock of the earth and the mountain still had a profound impact on him. He couldn't help but frown and said, "Why don't we have such a thing?"

The Mongolians beside him looked at each other and shook their heads: "Your Highness, there is no suitable craftsman in our country to make firearms. Besides, we Mongolians are good at bows and horses and are good at riding and shooting, so we don't need such things."

Kublai narrowed his eyes, obviously not approving of their answers, but just looked at Zhao Bi: "Mr. Zhao, do you know gunpowder?"

Zhao Bi suddenly became embarrassed. He was a scholar in the Jin Kingdom. He was a scholar in the clouds and had been with Confucius and Mencius all his life. He was familiar with poetry and books, and was full of knowledge. How could he learn how to study the firearms and gunpowder that only craftsmen would think about? Kublai Khan's question was simply a disgrace to his ethics.

However, he also understood that the Mongolians did not understand the Confucian principle that the son of a daughter could not sit in the hall. Kublai Khan had no insult to ask this question, and he was completely curious about new things.

He coughed and bowed, "Your Highness, gunpowder is a heavy weapon for the Song people. Private ownership is strictly prohibited by the people, and private development outside the official yard is prohibited. At that time, the Jin people had to get it. Therefore, except for the Song people, there was nowhere to be found, and even with money, I couldn't buy it. I lived in the Jin Kingdom in my early years, and later went to the Great Mongolian Kingdom to serve His Highness, so naturally I didn't have the opportunity to get it."

Kublai looked at him disappointedly, and looked at the place where the black smoke was still rising in the distance. His eyes regained his wolf-like light, and his domineering and ambitious expression returned to his face, and the emotions frightened by the explosion swayed.

He pointed the horse whip towards the direction of the wooden wall and said hatefully: "It's okay. Since the Song people have this thing, then let's catch some of the Song people. There are always people who know where to get it. This thing is fierce and can destroy the world. If we have it, just the Song people's strong cities and forts will be as loose as paper. At that time, what's the difficulty of drinking horses south of the Yangtze River?"
