This kind of iron pipe is not poured, and the toughness is very good.

The moment he saw the flint, a spiritual light flashed in Yan Ming's mind - a flintlock pistol.

Although it appears that the military crossbow fires much faster than the flintlock gun. But the range is not as good as that of a flintlock pistol. According to the current iron-smelting process of the Han Dynasty, it is absolutely impossible to produce flintlock pistols in large quantities.

But it is still possible to build a few flintlock pistols with a little effort.

Of course, the barrel is only the first step. The rest of the stuff still needs to be studied.

Holding the iron pipe, he returned to the Yunzhong County Shoufu like a baby pimple, and Yan Ming immediately locked himself in the study.

Yanran came in several times to bring him water, and saw a thick layer of straw paper piled up on his table.

Yan Ming rubbed the corners of his forehead from time to time. After all, he was not a professional designer in the military industry in his previous life. Because of his hobby, he only studied cold weapons and military crossbows, but he didn't have a deep understanding of thermal weapons. Just know how this kind of thing is used and manufactured.

This made it extremely difficult for him to draw.

Yan Ran looked at what Yan Ming had drawn on the drawing, covered her mouth and smiled: "What is this, it looks like a burning stick." ”

Yan Ming was also a little tired, and when he saw Yan Ran, he couldn't help but smile and said, "This is a gun." As he spoke, he stretched out his hand and took Yan Ran over.

Yan Ran symbolically dodged for a moment, and let Yan Ming's hand roam around her waist.

"Guns, I've never seen a gun like this. Like a burning stick, can you defeat the enemy? I think the third brother Wei Qing's lance is not bad, but most people can't use it, let alone us female soldiers. Yan Ran said while twisting her waist and avoiding Yan Ming's magic hand.

"This kind of gun is not the same as the spear you said, this one can be fired, just like I fired it on you!" Yan Ming smiled evilly.

Yan Ran naturally understood what he meant, laughed coquettishly, and was about to hit Yan Ming, but he caught it with his hand and said with a smile: "No, the lead is ignited, if you don't launch it, you can't do it." ”

"Get out of here—"

"Just don't roll."

"Tap ......"

and Yanran messed around, and both of them were out of breath.

"Your gun is so tight, what are you doing with these burning sticks!" Yan Ran sighed as she straightened her clothes.

After a toss, it seemed to make Yan Ming's mind suddenly brighten. Several problems that had plagued him before were solved.

Seeing that Yan Ran's face was still a little crimson, Yan Ming leaned over and kissed him fiercely, then said with a smile: "My gun is to create people, and that burning stick gun is to kill people, the meaning is very different!" ”

Yanran took a bite of him and said, "I'm not ashamed." ”

Yan Ming laughed and said, "When I make it, I'll give you a self-defense first." ”

Yanran knew that most of what he said would not be false, but she still smiled: "You just blow nonsense, I won't accompany you, lest you be shot again." ”

Yan Ming stretched out his hand to grab her, but she dodged and ran out.

After reminiscing about the battle just now, Yan Ming gathered his thoughts and wrote down the aura just now.

For three days, Yan Ming read in the study. Wei Qing came a few times, but he didn't see Yan Ming. Knowing that there must be something wrong with him like this, he quietly retreated without bothering.

These days, the surroundings of the city in the clouds are constantly sentry, and although the small cavalry of the Huns does not easily approach the clouds, they always appear hundreds of meters away.

Seeing that the city wall in the clouds facing them had been repaired, these Huns were shocked.

In their minds, nothing dries out so quickly.

The cement and blue-brick walls towered majestically in the wilderness, isolating the Huns who were eyeing each other.

This time, it was King Akuta who led the troops.

He was not led by their original tribe, but by two thousand elite cavalry under the command of King Zuoxian. Even this time, King Zuo Xian equipped him with five condor archers.

The Condor Archer is a marksman who is good at using a bow and arrow, which is equivalent to the current sniper.

The five Condor Archers are already extremely valuable in the army of the Huns.

The bow is like a full moon, and the strings sound and the eagle falls.

This is not a boast. The average archer is good if he can hit the target. The Condor Archer, on the other hand, can not only shoot wherever he wants, but also shoot farther than the average archer.

The Han army in Cloud City, Ah Guta has inquired clearly. It was led by two young people, one was the little marquis who gave the emperor a whisker and patted the horse, and the other was the brother-in-law who let the emperor sleep and took the opportunity to take the throne.

Ah Guta considers himself an eagle of the grassland and looks down on the Han sheep.

He is detailed, the Han army, but only by relying on the advanced crossbow arrows to win. Therefore, everyone in the cavalry led by Ah Guta this time put on heavy armor, and even the key areas of the war horses were covered with armor.

Just let them get close to the walls, and it would be easy to tear down the newly built walls.

After so many days of construction, the walls of the city wall have basically been completed. The city wall on the north side has been blocked by Lao Xu, and it is almost a tall city wall of cement and blue bricks.

On the city, fire and thunder catapults, as well as eagle crossbows, were erected one after another.

The 2,000 heavily armored cavalry of Aguta finally appeared in Yunzhong City, the border of the Han Dynasty.

Seeing those heavily armored cavalrymen who only showed their eyes, the Han army also felt depressed.

"The heavy armored cavalry is the cronies of King Zuoxian of the Huns. Because of the extremely high cost of wearing heavy armor, King Zuo Xian only had a heavy armored cavalry of 4,000 people. Unexpectedly, there were 2,000 people here this time, and King Zuo Xian looked up to Cloud City too much. Wei Qing looked at the cavalry outside the city and said with a light smile.

"General, it doesn't matter what kind of heavy cavalry he is, our military crossbow is aimed, and he will shoot the same damn thing." Wang Dajian said on the side.

Wei Qing shook his head and said, "The armor of the heavy armored cavalry is extremely thick, and our crossbow arrows began to deviate after sixty steps, and their strength weakened a little. I'm afraid it won't be possible to shoot these heavy cavalry effectively. ”

Wei Qing's analysis is not unreasonable. Wang Dajian also knew that these heavy armored cavalry were powerful.

"What then?" Wang Dajian was a little anxious.

"If you really can't do it, you can only use fire thunder!" Wei Qing said.

Many of the Hu Cavalry Captains have seen the scene after the explosion of the fire and thunder, but they do not know how to use the fire and thunder. Now that he heard Wei Qing say that he wanted to use fire thunder, he had a hint of expectation.

"But this matter still needs to be approved by Yan Hou." Wei Qing said.

Everyone knows that the fire thunder was invented by Yan Ming, so naturally only Yan Ming understands how to use it.

"I'll go and discuss it with Yan Hou. Here you take a closer look at the heavy cavalry on the other side. Wei Qing said and left the city.

Now Yan Ming has been in the county guard mansion for half a month. For half a month, he saw no one except the blacksmith and the carpenter.
