"I understand?"

Qin Feng smacked his lips, he really understood. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

These horses are all war horses, not ordinary horses, what have you not seen on the battlefield? All of them are warriors, and they usually shout twice and set fire, these horses will not blow up the herd.

Qin Feng was suddenly ashamed, and said in his heart that he was killed by the TV series, and when he held a torch and shouted, the enemy's horses were frightened, and it was really nonsense. Such a horse can't become a war horse at all, and it can't be a battlefield, but any horse that can go to the battlefield is difficult to be scared. If you are scared casually, then there will be no cavalry in this world, but a 'tank army'.

As soon as the other side shouted, the horse was frightened and farted.

Qin Feng said ashamedly: "It seems that things are as simple as they think. Perhaps, it's really time to retreat, go, go out with me. ”

So he took Jia Xu and Pang Tong out of the big tent and went to inspect everywhere.

One foot deep, one foot shallow, didn't take a few steps, Lao Jia Xu couldn't walk, he couldn't walk.

Qin Feng is also very difficult to walk, in this case, how to attack the enemy?

Just when Qin Feng retreated even deeper, he heard a crackling sound.

When everyone walked over to take a look, they saw a group of soldiers, surrounded by a fire, bursting 'firecrackers'.

The firecrackers at this time were very different from the firecrackers that came later. It is to burn the bamboo pieces with fire, etc., and the bamboo pieces crack open, making a crackling sound.

"At this time, it is already the New Year in my hometown......."

The soldiers muttered, homesick.

"Stand upright!"

In an uproar, the soldiers found Qin Feng and immediately stood up and saluted.

Qin Feng returned the salute and signaled the soldiers to be casual and not to care about his arrival. He also threw a firecracker into the fire himself, listening to the crackling sound and sighing. Suddenly, Qin Feng came to inspiration, and said to Jia Xu urgently: "How about using firecrackers?" ”

The soldiers didn't know what the lord was asking, but Jia Xu knew it.

Jia Xu thought for a while and said: "Lord, firecrackers need to be thrown into the fire or brazier, and they will crack and develop sound after burning for a long time, and the operation is very complicated and the process is long. Our army sent people to infiltrate, but there was no time to operate, and there was definitely not enough manpower. In addition, although the firecracker sounded, the sound was still quieter. ”

Qin Feng pondered for a while, and then felt that what Jia Xu said made sense, but he didn't give up, so he said: "If you make a new 'blast', it is easy to operate, and it will explode when you throw it out, and the sound is very loud, and it can really explode, and the fragments will scatter, just like lightning splitting wood, what do you think?" ”

Jia Xu and Pang Tong glanced at each other, couldn't hide their surprise, and said in unison: "Is there really such a thing?" ”

"If sometimes, how?"

Now this kind of firecracker, looking at a bamboo character, you can understand that it is a piece of bamboo thrown into the fire, and after burning, the bamboo piece will crack and make a sound. The bamboo pieces just cracked, not exploded into pieces and flew out, the sound was small, and it was not lethal. It's okay to make a fuss, it's not combative.

But the 'explosion' that came out later was different, it could be blown into pieces, it was lethal, and it was loud. If there are a large number of them, they can kill people, which can be seen.

Pang Tong said: "If there is really this thing that the lord said, it will definitely succeed." ”

Looking at Qin Feng and the others in the distance, the soldiers were incredulous, full of question marks, "Explosive war?" ”

Returning to the big tent of the Chinese army, Qin Feng became eager.

Making real firecrackers is difficult, but blasting is simple. Qin Feng vaguely remembered that in ancient times, people filled saltpeter, sulfur and charcoal into bamboo tubes and burned them, resulting in a "blast war". In the Song Dynasty, the folk began to use paper tubes and hemp stems wrapped in gunpowder to weave strings to make "cannons" (i.e., firecrackers).

"Saltpeter, sulfur, and charcoal are mixed together, and when ignited, they can burst and become a 'blast'." Qin Feng said.

Jia Xu and Pang Tong were full of question marks.

Jia Xu asked, "Lord, where did this recipe come from?" ”

Qin Feng could say that he had learned from the next generation, so he had to say: "I suddenly thought of it." ”

The lord has just come up with it! The two were shocked, and their hearts said that they could figure this out? The Lord is truly the Holy Lord. To be sure, there is no such thing in the world as the Lord said. But countless facts have proved that the whims of the lord will always come true.

Jia Xu immediately said: "Lord Shengming, if you can really make this explosive battle, it will be great, the enemy horses will blow up the group, and it will become a situation of horses stepping on the joint camp." As soon as the enemy is in chaos, our army will rush forward, and it will be a complete success. ”

Pang Tong is also very sure of this, "The main thing is this explosive ......." ”

Qin Feng sent a message to all the generals and told them that they had found a way to defeat the Xianbei people, and they must persist in the ice and snow.

The ministries learned that there was a way to defeat the Xianbei people, so they strengthened their faith and continued to persevere.

On the other hand, Qin Feng ordered to collect saltpeter, send sulfur to the army, and use the wood from the camp to make wooden tubes. The bamboo tube is not easy to find, so it is temporarily replaced by a wooden tube, on the one hand to make a wooden tube, and on the other hand to burn charcoal.

Sulfur was discovered and recorded thousands of years ago, and although ordinary people didn't understand it, Qin Feng, Jia Xu and Pang Tong all understood it.

meeting.

Qin Feng asked Saisang, "Father-in-law, there must be sulfur in the inner grassland, you can recall." I remember that there were a lot of sulfur mines near the inner grasslands to the outer grasslands. ”

What he said was not unfounded.

Saisan recalled it and said excitedly: "Yes, there is this thing." Sulfur is also often used to smoke things, and it is found in the Urad steppe, not far away. ”

The sulfur is solved, and the next thing is saltpeter.

In fact, saltpeter is even easier to obtain.

At this time, it was recorded in the books: saltpeter, a kind of white bitter crystal, likes to stay at the foot of the wall at low temperature, the color is like frost, so it is also called "wall frost". After the Mid-Autumn Festival, that is, in the living room, sweep the floor every other day, and take a little for refining.

The roots of the wall can be swept out!

And the nitrate and the salt have the same mother, and the moisture under the earth is steamed, and it is now on the ground. Those who are close to the water and the soil is thin become salt, and those who are close to the mountains and the soil is thick become nitrate.

The steppes of Inner and Outer Mongolia were full of rock salt mines, and the Mongolian cavalry ate horse jerky made of rock salt, which swept across most of Europe.

Qin Feng recalled: "There is a mountain in the back, you can go to the foot of the mountain to find it. ”

Now that there is a plan to break the enemy, the coalition forces began to continue to hold out.

Five days later, sulfur and saltpeter came to the front of the army, and Qin Feng's charcoal and bamboo tube were almost made.

In front of the big tent of the Chinese army.

Qin Feng wore armor and a mask and helmet, and filled the wooden tube with a ratio of charcoal 2 saltpeter 1 sulfur 1.

Everyone watched.

Saisan and the other tribal leaders muttered.

"Okay?"

"Can you really make the kind of powerful 'explosion' that is described?"

"There is no food left, if we can't make it, we can't break the enemy, and we can't go back." They were so worried that they began to think, "Can the charcoal explode if you put some charcoal in the 'stone'?" That's not.
