~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The box opened, and a thunder cannon was placed squarely inside.

In the bloody battle of Donggeng Fengsui, Zhang Fang exhausted the last bit of raw materials, but after coming to Jiaohebi, Zhang Fang immediately confessed to Deng Zhan, Qingyan and the Han brothers to secretly replenish the raw materials. When Zhang Fang bought raw materials, he was not stupid enough to buy only three, but mixed a lot of irrelevant things. Except for Qing Yan, who participated in the production of the thunder cannon, even the handlers like Deng Zhan and the Han brothers did not know the true composition of the thunder cannon.

It's not about trusting or not, but about something, the more you don't know, the less you have to be responsible. It's good for their safety, as well as for the recipe of gunpowder.

If it is a different place, Zhang Fang may not be so attentive to buying raw materials. After all, there are not many places in China where saltpeter and sulfur are produced, and it is possible to buy small quantities, but there is nowhere to buy large quantities. However, who let him come to Jiaohe?

Where is Jiaohe? It was in Turpan in later generations. When you talk about Turpan, what is the first thing that comes to mind? Grape! Fruits! Flaming Mountain!

Flaming Mountain is an extinct volcano that was originally one of China's largest sources of sulfur and saltpeter.

Zhang Fang almost immediately made a decision that in the future, he must set up a shop here to specialize in purchasing sulfur and saltpeter. Therefore, this procurement is not only to supplement raw materials, but also to establish contact with local sellers and lay a good foundation for future cooperation.

Of course, for this level of businessmen, Zhang Fang does not need to end up in person, and Deng Zhan is just right.

In the box is a thunder cannon that Zhang Fang has just made, because it was handed over to the two lieutenants for testing, so the thunder cannon was specially painted with a layer of red paint, which looked like a large cannon.

"This is ......" Chen Tang held it in his hand and couldn't understand it for a long time.

"This is what the Huns call 'thunder fire'!"

"Ahh Guo Xigang stretched out his hand and wanted to take it over to take a closer look, but Leng might as well listen to Zhang Fang's words, and suddenly retracted his hand like touching a fire. Immediately realized that he had lost his temper, his old face turned red, and his expression was sneering. It's no wonder that he had this reaction, it was really the fear of the Huns, which had a considerable impact on him. The doctrine of the destiny of ghosts and gods is not only rampant in the Western Regions, but also in the Central Plains of the Han Dynasty.

Zhang Fang gestured to Qingyan's jaw. The latter understood, stepped forward with his skirt raised, and stretched out his hand: "Let's let the little maid demonstrate it for the two captains." ”

Zhang Fang stood up and said solemnly: "There is a vacant space on the hillside behind the wooden building, which is suitable for demonstration. Please come with me, both of you. ”

A group of four people was in front, and more than ten people were behind, and they crossed a hill, and sure enough, they saw a gentle slope.

On the grounds of secrecy, Zhang Fang asked all the servants to wait behind the hillside, and only Chen and Guo were allowed to go together.

Zhang Fang and the three of them stood on the slope, but when they saw Qingyan's slender hand raised, a red shadow crossed by, and there was a loud bang on the ground, the sound shook the valley, and the echo was endless.

Rao is Chen Tang and Guo Xi had a certain amount of psychological preparation in advance, but they were still shocked by this unheard roar, and they lost their breath, and they even turned a blind eye to Qingyan stepping forward to give a salute and accuse him.

Zhang Fang didn't make a sound, just waved his hand lightly, signaling Qingyan to step aside, silent and silent, waiting for the two captains to digest it slowly.

After a few more breaths, Chen Tang came back to his senses, took a step forward, grabbed Zhang Fang's wrist, pulled up the corners of his eyes, and looked excited: "This thing...... Who made it? ”

Zhang Fang smiled and said nothing, Qingyan couldn't help but interject: "Then it goes without saying, of course it's Gongzi's invention." It's called 'Thunder Cannon'. ”

Thunder cannons? Chen Tang nodded, shook his head again, and said strangely: "The sound is like thunder, the sound is like a drum, isn't it good to call it 'Thunder Drum'?" Why is it called 'Thunder Cannon'? What is the explanation of this 'cannon'? ”

Thunder drums? Zhang Fang was speechless, this name is too strange. I don't know that in the concept of the times, the name of this "thunder cannon" is wonderful. Because in the Han Dynasty, there was no word for "cannon" at all. This is purely Zhang Fang's invention, and no one else can write it except him.

"How much does Childe have in his hands?" Guo Xike, who came back to his senses, didn't care whether it was a thunder cannon or a thunder drum, and only asked the question he was most concerned about.

This is not easy to answer, can you say that as long as the raw materials are sufficient, how much is needed? Zhang Fang smiled: "It's enough to fight another Fengsui defensive battle." ”

"No wonder the Huns are overwhelmed and have palpitations." The shocked expression on Guo Xi's face had not completely faded, he walked quickly to the scene of the explosion, and sighed after an investigation, "It's the Han army, and it's ...... to be attacked like this suddenly."

"If a cavalry attack with this weapon is a surprise attack on the battlefield where the two armies are arrayed, it will surely cause chaos in the enemy's formation and break it in one fell swoop. Wonderful! Chen Tang's face flushed, his eyes lit up, and a bold idea that had been churning in his heart since his westward journey surged again. Suddenly looked up at the northwest, his lips moved, and he wanted to say something, but he finally held back.

At this time, the servants who heard the explosion rushed in a hurry, and it was still a landslide, and when they saw the three of them talking and laughing, there was a place of red confetti, and there was nothing else unusual. I couldn't help but look at each other, surprised.

"Childe's ingenuity, Xi can only admire, and he will report to the imperial court ......" Guo Xi blurted out excitedly, and immediately woke up and stopped.

Sure enough, Zhang and Chen both looked at him and smiled. Guo Xi bowed his hand, looking embarrassed.

If a common man invented such a sharp weapon and dedicated it to the army, Guo Xi should say so. But who is Zhang Fang? The prince of Fuping, the nephew of the Son of Heaven, when it comes to listening to the heavens, you can't even beat a horse as a lieutenant.

Therefore, the best procedure is to wait for Zhang to return to Beijing and report to the imperial court himself. After the imperial court approved mass production, they waited for the arms to arrive.

Seeing that Chen and Guo were overjoyed, Zhang Fang had to pour cold water on them: "Although this thing can make a loud noise, it is not enough to kill, if it is used in the battle array, it can not be used again." ”

"So...... What about increments? Chen Tang was to the point.

"This thing weighs half a catty, if you want to achieve a certain lethality, at least three catties, and to achieve the ideal lethality, at least five catties." Zhang Fang smiled wryly and spread his hands, "How far can a five-pound thunder cannon be thrown?" ”

"That's ......" Chen Tang and Guo Xi glanced at each other, and couldn't help but be disappointed. They are all good at the military, and they know that the most important thing in throwing weapons is distance, and sufficient distance is meaningful in actual combat. Can you throw twenty steps into such a heavy thing? How many votes will be exhausting?

After a while, Guo Xi took a long breath, twisted his beard and smiled: "It's okay, at least it's a sharp weapon." ”

Zhang Fang nodded, that's right, this is the correct usage. Explosives are used to defend the city, or to besiege the city, or to guard the city.

Only Chen Tang sighed, but it was a pity, I thought that with the help of this sharp weapon, I could do something great......

"Alright, let's go back." Zhang Fang turned around and walked, and when he passed by Chen Tang's side, the corners of his mouth curved into a mysterious smile: "Chen Jun doesn't need to worry, what you want will be achieved." ”

Chen Tang's heart jumped inexplicably, and he was about to ask, but Zhang Fang had already taken Shi Shiran and walked away.

Looking at the tall figure that was gradually moving away, Chen Tang's heart once again swelled with an inexplicable sense of mystery......
