Facing the "artillery" that suddenly popped out of Zhang Hao's mouth, Dugu Junjie was stunned, hesitated for a while, and then stammered a little and said, "Young master, this is ...... This...... Artillery...... What is it? Can I look at the real thing? I can't define the utility of the actual object without seeing it. ”

Zhang Hao smiled: "Of course, but before that, think about it, if there is a weapon that has far more power than a trebuchet, the accuracy of a strong crossbow, and the range is even several times or more than ten times that of a strong crossbow, and the speed exceeds the speed of an ordinary flying sword in the Yuan Infant Stage, and it has the power of self-explosion in the Yuan Infant Stage, how would you use this weapon?"

"Ah...... Is there really such a weapon?"

Not only Dugu Junjie, but even Zhang Shengde was a little surprised-what kind of explosives and artillery that Zhang Hao had been making up recently, did it really have such power? Wasn't it just a combination of some powder mixed with steel?

"Come with me!" Zhang Hao got up and walked out.

Zhang Hao took his father Zhang Shengde, his second uncle Zhang Shengye, his eldest brother Zhang Han, and Dugu Junjie to the research base in the rear together. When I entered the research base, I saw two artillery pieces.

In addition to the first-generation prototype, Huang Mingshan and others are in the final inspection of the second-generation prototype. Compared with the first generation, the second generation design is more mature and reasonable.

The first generation was groped out in a state of confusion, and the second generation is very mature and the design is more reasonable. The length of the barrel has not changed, but it is much more slender and has a bit more industrial beauty. The unique dark black color of the quenching makes the cannon a little darker and more hideous.

Outside the cannon barrel, a sealing formation was also added - this formation was used to strengthen the cannon barrel, but it also made the cannon more mysterious.

In addition, all components have been optimized and adjusted.

However, the withdrawal system has still not been invented - because until now, the artillery has not really been fired, there are many problems, and it is inconvenient for Zhang Hao to reveal it 'ahead'.

And so far, all the tests have been carried out with small iron pipes, or alone, small-scale attempts at explosion power, etc.

All of this is quite a bit behind closed doors, but the difference is that Huang Mingshan and others have a solid foundation and can replace some experience accumulation through mathematical calculations.

Dugu Junjie circled around the artillery several times, but he didn't see anything.

This is said to be a weapon that comprehensively surpasses the trebuchet + giant crossbow, without the torsion spring of the trebuchet, nor the exaggerated and powerful bow arm of the crossbow. Only at the end of the barrel is a structure less than half a meter in size, similar to a normal hand crossbow.

Zhang Hao looked at the lonely and handsome appearance, and he didn't explain. Instead, he asked Huang Mingshan about the specific situation.

Huang Mingshan dragged a large box from the side, and twelve black-gray shells were placed in it. "Young master, this is all the shells that have been built so far. In order to better seal and make good use of rifling, on the outside of the shell, we used the method of melting plating to coat a layer of lead-tin alloy.

The lead-tin alloy is soft, can be better sealed, and can be used as a lubricating layer, which will not wear out the rifling of the barrel, etc.

The inside of the shell is ultra-hard hardened steel, which is brittle and has sharp fragments.

The warhead of the shell had a diameter of 10 centimeters, a length of 40 centimeters, a charge of 8 kilograms, and a total weight of 16 kilograms;

The diameter of the shell is 12 cm, the length of the shell is 60 cm, and the propellant is 1.2 kg.

The preliminary estimate is that the maximum range of the shells should be more than 10 kilometers, and the power of the explosion will spread to a radius of 100 meters in diameter. Specifically, it needs to be measured. ”

"Very good, let's start the actual test today!" Zhang Hao looked at the twelve black-gray and even some rustic shells, but his heart was very excited.

The seaside area of Changshan Town, where Zhang's family is located, is a barren area, almost uninhabited, and the guards quickly determined a no-man's land, almost seven or eight kilometers wide and 20 kilometers long, with only a dozen meters of height along the way.

At the target location, a large number of wooden stakes, one foot thick and one person high, were placed to test the power of the shells.

Both artillery pieces were dragged out, and Huang Mingshan and the others were the most excited, and the artillery that had been studied for a long time finally had a chance to exert their might. I just used a small iron pipe to study before, and I was really a little aggrieved.

Senior Brother Feng Zhiling jumped out of nowhere to watch. Zhang Hao turned his head to see that Feng Zhiling had a jade pendant hanging from his waist, with the words "150,000" on it. That's right, Senior Brother Feng also invested in Dayang Group with himself, and he sold himself for 150,000 high-grade spirit stones.

After Zhang Hao saw Feng Zhiling, a smile suddenly appeared on the corner of his mouth: "Senior brother, do you want to fire the first shot?" This is a weapon with a power comparable to the self-explosion of the Yuan Infant Stage, and the range is expected to reach 10 kilometers. ”

"Okay!" Feng Zhiling was immediately excited. There is fun, the junior brother thought of himself at the first time, enough righteousness!

Huang Mingshan and others adjusted the angle, proofread the direction, and for the sake of prudence, they lifted a lot of stones and pressed them on the frame, and then Huang Mingshan and others retreated more than ten meters under Zhang Hao's signal, and Feng Zhiling was left in front.

Feng Zhiling finally felt that something was wrong, and turned his head to look at Zhang Hao and the others, Zhang Hao smiled, "Senior brother, this is also the first time we have tried to launch this thing." So, while the first shot is significant, there may also be some unknown dangers. Look, do you want to change people?"

When Feng Zhiling heard that he was going to be replaced, he immediately shook his head: "Isn't it dangerous, senior brother, I'm not afraid! I'm ready, I'm going to shoot!"

Haha......"

Feng Zhiling roared excitedly, and after adding defense to himself, he suddenly pulled the trigger, the bowstring instantly relaxed, and the firing pin collided with the bottom fire of the bullet case, making a crisp sound.

But the next moment......

"Boom!"

There was an indescribable sound, like a thunderbolt erupting on the ground, and a ball of flame frantically rushed out of the muzzle, and the billowing smoke filled the air.

A faint black dot swished and disappeared.

There was a faint screech in the air, but it was almost completely muffled by the sound of the artillery itself.

And the artillery itself jumped up directly, and the stones pressed on the artillery frame were overturned a lot, and the artillery retreated as much as one meter on the ground, and Feng Zhiling was directly knocked back as much as two meters.

"What the hell!" shouted Feng Zhiling.

Not to mention Feng Zhiling, even Zhang Hao and the others were taken aback, the scene just now was too 'powerful'. Dugu Junjie's eyes were still a little stunned.

Zhang Hao rushed to Feng Zhiling's side and asked with concern, "Senior brother, how is it?"

"What are you talking about? Be louder, I can't hear you. Feng Zhiling yelled at the top of his voice.

Zhang Hao could only shout at the top of his voice: "Senior brother, are you okay?"

"Ah, it's okay, of course it's okay! It's so cool! Come again!" Feng Zhiling excitedly walked to the second cannon, ready to fire again.

"Wait!" Zhang Hao stood in front of Feng Zhiling, "wait for the first shell to explode." And it's not loaded yet!"

"Explosion?"

"Wait half a minute. Ten seconds have passed, and there are still twenty seconds left. ”

After Zhang Hao finished speaking, he quietly looked into the distance, and everyone waited quietly, especially Huang Mingshan and others, who were even more excited. The firing scene of the artillery is already very shocking, I don't know what the explosion scene is?

Time slipped away little by little, and I saw half a minute.

Suddenly, a cloud of smoke rose in the distance, and the muddy smoke and earth tumbled up, and countless birds panicked. Some of the sea monsters on the beach are even more chickens and dogs. After waiting for a while, there was a faint roar of thunder.

"Let's go, go over and have a look!" Zhang Hao took the lead in flying forward, but he flew very slowly. Feng Zhiling flew over and grabbed Zhang Hao by the way. After a while, he flew over, standing on a small hill next to him, looking at the crater in front of him, Zhang Hao also gasped.

Ahead, there is a large crater almost three meters deep, twelve or thirteen meters, and the edge of the crater is like an axe chisel.

Within 30 meters of the crater, all the wooden stakes were overturned, and most of them were miserable; only a few broken wooden stakes stood crookedly 30 meters away, and many of the wooden stakes disappeared directly as if they had been bitten.

It wasn't until 100 meters away that some of the stakes were stuck with broken shrapnel. The shrapnel was irregularly wrecked, but they were all very sharp.

"It's all good steel!" Feng Zhiling picked up a piece of shrapnel, a bit of a pity.

Zhang Hao smiled and asked, "Senior brother, what do you think of the power of this explosion?"

Feng Zhiling's ears had recovered at this time, he looked sideways at the crater, looked around, and said slowly: "It almost has the power of the Jindan peak self-explosion." But if the lethality of shrapnel is added, it is about equivalent to a self-explosion in the early days of the Yuan Infant. ”

Zhang Hao nodded with satisfaction and beckoned everyone to go back and continue the experiment. At the same time, he turned his head and asked Dugu Junjie: "How is this artillery?"
