In the past month, Xia Fox often came back to Xia Qi, and in order to be released by Xia Qi in advance, he even used the coquettish that he had never used.

However, His Majesty the Emperor insisted on the bottom line, saying that when a month's leave is taken, then one day must not be missing!

Finally, a month has passed, and Xia Fox has finally been "released from prison".

It's also interesting to say that Xia Fox once approached Xia Qi and wanted Xia Qi to release her in advance in order to reward her.

Then, Xia Qi refused without hesitation.

The reason is that half of the Ordnance Research Department was blown up by you, and it is still being rebuilt, so you dare to come to me and ask for a reward?

Hearing this, Xia Fox's face obviously flashed a trace of emptiness, and when he saw that this road was not working, he struck again, and simply played a trick in front of Xia Qi.

"I don't care! You said I'd give me new weapon blueprints as soon as I figured out the recipe for gunpowder! I've researched it now, give it to me~ I want it! I'm going to ......"

Looking at Xia Fox, who was about to roll all over the ground, Xia Qi couldn't cry or laugh for a while.

At the same time, during the month of the long vacation for Xia Fox, under the full supervision of the deputy director of the Ordnance Research Department, the stable formula of gunpowder has also been figured out.

In the current situation, the research on weapons and equipment should hurry up to keep up.

Thinking of this, Xia Qi sighed heavily, and then took out a thick stack of design drawings that had been prepared a long time ago.

What is recorded on this blueprint is a firearm called a stone cannon, which is a gold-level prop that Xia Qi spent a lot of money to get from other players.

Xia Fox, who saw the design, was like a cat that smelled fishy, his eyes were shining, and he rushed up and wanted to take the design away.

Xia Qi's eyes were quick, and he hurriedly raised the design drawing in his hand to the top of his head, looked at Xia Fox, who was jumping and crazy, and then said with a smile: "Let's talk about it first, if you make any more trouble this time, I will directly give you a half-year long vacation, understand?!" ”

When Xia Fox heard this, his little face instantly turned pale.

This month's long vacation is enough for her to endure, and she has to kill her for half a year?

"Your Majesty, are you the devil?"

"Did you hear that?"

"Well, I heard you."

"Take it."

As he spoke, Xia Qi handed the stack of design drawings he held in his hand to Xia Fox.

Xia Fox, who took over the design drawing, looked through it on the spot.

The shape of the stone cannon on the design drawing was undoubtedly new to her.

After flipping through the two pages, Xia Fox couldn't help but ask out loud, "Your Majesty, is this an upgraded version of the bed crossbow?" ”

Hearing this, Xia Qi raised his eyebrows slightly, it was really a shame that Xia Fox could see the shadow of the bed crossbow from the stone cannon.

However, this is not entirely true.

"If anything, it should be a weapon that combines the characteristics of a bed crossbow and a catapult."

The positioning of the bed crossbow and catapult itself is equivalent to the ancient siege cannon.

The bed crossbow is characterized by penetrating power, and the catapult is characterized by the destructive power of a blunt blow, and the cannon combines both properties.

However, for the stone cannon, Xia Qi didn't have much expectations at all, this was at best an opportunity for his Daxia to step into the "firearms".

The range of this thing is not as good as that of the Eight Bull Crossbow and Catapult, and the accuracy is quite poor.

Instead of mass-producing catapults, it would be better for him to continue with the Eight Ox Crossbow and Catapult.

But soon Xia Qi came to his senses, the design drawings he opened were indeed stone cannons, but did the system stipulate that he could only build stone cannons!

He is a modern person, can't he improve on this basis?

Early cannons, collectively known as smoothbore guns.

The origin of the name is due to the fact that the inside of the barrel is smooth, and the stone cannon, apparently also scored in the category of smoothbore guns.

The common problem of smoothbore guns is that they have a short range and poor accuracy.

But Xia Qi can improve on this point, based on the design of the stone cannon, and directly improve it into a rifled cannon?

The most important feature of rifled guns is that the inside of the barrel is engraved with rifling.

Therefore, when the cannon fires, the flying shells will rotate along the trajectory of the rifling on the inside, so that the less stable shells can achieve the effect of stable flight, and at the same time, the range and accuracy of the cannon will be significantly improved!

Of course, if you want to make a rifled gun barrel, you have quite high requirements for manufacturing technology and technical ability.

There is also the structure of the entire gun body, due to the change in the way the gun is fired, the whole structure has to be changed.

However, Xia Qi is fearless, he has the technical and technological power of both humans and goblins in his hands, as well as Xia Fox, a top ordnance master.

Can this still stump him?

Between the thoughts flying, Xia Qi directly referred to the design drawings and gave Xia Fox a simple explanation.

"This part is called the barrel, this is the shell, and this part inside is used to fill the gunpowder."

"However, there is a difference in this design drawing, the internal design of this barrel will cause the accuracy and range of the shell to become very poor, so ......"

As he spoke, Xia Qi quickly took out a design drawing on his desk.

The design drawing was drawn by Xia Qi himself, and the main content was the internal structure of the rifled gun, as well as some of his ideas for transforming the overall structure.

This is also thanks to Mingzhu, which Xia Qi asked Mingzhu to ask for information from an engineer who used to be a military museum.

For this reason, Xia Qi also paid a large amount of food in the past.

But in front of these artillery, it is worth it.

Xia Fox, who took over the design drawing, quickly flipped through it.

"I see. If you make such a trajectory on the inside of the barrel in advance, the shell will naturally rotate along these trajectories when it flies out, and the shell will become more stable if it rotates at high speed. ”

"This seems to be a very simple design, but it can effectively increase the range and accuracy of the shell, Your Majesty, you are really amazing, you can come up with such a design!"

"But I think if you want to do this, the shape of the shell should also be changed slightly, and the surface should also be traced accordingly, so that the effect can be better."

"And this structure over here, I always feel that something is wrong, Your Majesty, what do you say?"

Xia Qi: Abba Abba Abba ......

Xia Qi fell into a state of silence the whole time, and at this moment, he once again felt the difference between a mortal and a top genius.

He hurriedly drove Xia Fox away, which avoided being further hit by the other party.

The study of the cannon, Xia Qi pondered that it was enough for Xia Fox to toss for a long time.

And Xia Qi himself also seized the time to devote himself to the construction and development of Daxia.

-------------------------------------

Recently, there have been frequent disappearances of people in the mountains and forests of the Northland, and when people are found, their bodies have already been found.

And, all of them were disemboweled. At first, it was determined that the crime was committed by wild beasts, so the lord of the mountain castle sent additional soldiers to patrol the mountains and forests, but as a result, people were still missing.

This time, however, some people said that they had stumbled upon a very large bird that seemed to have something hanging from its claws.

But because it was night, the man thought he had seen it wrong, so he didn't care.

Only then did the lord of the mountain castle realize that something was wrong, and he realized that this big bird was only afraid that he was the culprit of these disappearances.

At the same time, this giant bird may be the monster recorded in the newspaper some time ago.

It was about the Warcraft, and the City Lord of Mountain City didn't dare to be careless, so he reported the news to Xia Qi.

After receiving this news, Xia Qi immediately looked at Xiaobai.

During this time, Xiaobai has completely controlled his body and is able to release magic, and it is time to let it go out and move.

Xia Qi first wrote a letter, in which he wrote Xiaobai's identity.

"Go, you follow it to the mountain city to play, and if there is a demonic beast, destroy it." Xia Qi took the wind falcon to Xiaobai's nest and said to it.

"Chirp."

Xiao Bai looked at Xia Qi, then looked at the wind falcon on his shoulder that was already trembling with his own fright, and then nodded lightly, indicating that he understood.

Immediately, Xia Qi released the wind falcon out.

I don't know if this little guy is too nervous, and in the process of ascending, his body has more than once traces of falling, and he has tried several times in a row before he can regain his balance in the air.

Seeing this, Xiaobai immediately stretched his wings and flew into the sky.

The wind falcon is known for its speed, and Xiaobai's flight speed is even better, and the two soon flew to the north of the mountains and forests.

Soon, Xiao Bai spotted a figure in the air in front of him.

The figure had a much larger body than ordinary birds, gray feathers, strong claws, and a long neck that was bare without a single feather.

The main thing is to highlight an ugly word.

At this time, this ugly creature is hunting, and as for the target of its predation, it is naturally the human below.

Only this time it happened to encounter a patrolling human force while hunting, and from the heavily armed soldiers, the strange bird felt threatened.

In the previous period, it would basically only pick out single targets.

Later, however, the Terrans became alert and began to move in groups, with patrolling soldiers nearby.

This made the strange bird have no chance to do it for a while, but now it really can't support it, and the hungry strange bird has to go out again.

And this time, it quickly attracted attention.

The moment they saw the figure of the strange bird, the people who were working outside the city immediately put down their work and ran wildly in the direction of the mountain castle, while the soldiers began to move in the direction of the strange bird.

At this time, the strange bird had lost his mind a little because of hunger and became very irritable.

After realizing that it had been discovered by humans on the ground, it did not hesitate to do so.

It began to descend rapidly, charging at a human who was still far from the city, and the strange bird clearly wanted to capture the human, and then feast on it, and then talk about the rest of the time.

The speed of the strange bird was so fast that the soldiers couldn't react at all.

Looking at the strange bird that was getting closer and closer to him, the human's face had turned pale.

At this critical juncture, an eagle's cry broke the deadlock.
