The lady who came back from the robbery turned out to be the proud female sword emperor

The erroneous term "Three points into the tree" can describe the scene at this moment. Of course, the bullet penetrated much deeper than the three-pointer. The lead bullet entered the tree trunk perfectly and got stuck deep. Li Yunfei could hit the tree trunk. See circular bullet holes.

In the era of flintlock guns, the caliber of the barrel was generally large. Due to technical problems, it was impossible to make a small barrel~

Chapter 774 Wangshu and Xihe

If this is used to target creatures, the power is definitely not small, and it is much more powerful than the previous firecrackers with a much smaller caliber.

"The power is very good. Even a master of external martial arts will be injured. A master of internal martial arts may be shot to the head before he realizes it."

Fu Shishuang walked to Li Yunfei's side, she observed the small hole in the tree trunk, her eyes narrowed, observing very carefully.

Although internal martial arts fighters are stronger than external martial arts fighters, it is only limited to when the body is full of internal energy. If there is no defense, ordinary internal martial arts fighters have no way to compare with external martial arts fighters in terms of ability to resist blows.

If it is some external skills masters who have cultivated to the level of copper skin and iron bones, it seems that the body is always protected by inner energy. Yunfei's shot should not be fatal, at most it can only cause minor injuries.

"It's amazing! Husband, what is this called in your hand? You really don't need to light the match!"

Bai Wushuang leaned over and said in amazement, when her husband made the firecracker before, she thought it was a novelty, but she didn't expect her husband to come up with something even more powerful now.

"The flintlock gun is different from the firing principle of the previous firearms. This time it uses flint to ignite the fire."

Li Yunfei explained, and then suddenly had some novel thoughts in his heart.

Flintlocks actually have a lot of shortcomings. Compared with automatic rifles, flintlocks are not allowed to run multiple times from the ammunition and mechanical structure, and if the ignition method of the flintlock is heavy rain, the probability of successful ignition may be lower. Not high.

Of course, that was also the case of heavy rain, which was much better than matchlock guns like firecrackers. Matchlocks were so strong that they might not be able to ignite if they encountered very little water.

If you want to update and strengthen it in the future, then...why not try the switch ignition?

Replace the flint ignition with a switch, the battery or something may be made in the future, and even if it cannot be made, there should be something to replace it... such as inkstone.

Since the energy inside the inkstone can be converted from electrical energy, then the reverse conversion... under certain conditions should also work, right?

Thinking of this, Li Yunfei nodded. He can put some thought into it in the future, and maybe he will have a thorough research at some point, so isn't inkstone a new type of battery?

"This name is not very domineering, my husband, you choose the name so casually."

Bai Wushuang interrupted Li Yunfei's thinking. She felt that her husband could make some novel things every time, but the name was surprisingly simple. She thought of firecrackers, flintlock guns, and engineer shovels. , I feel that the name has no characteristics and no taste.

"Isn't it nice?"

Li Yunfei was taken aback, he had never thought about the name at all, but the women present all nodded together, it seems that his taste is really low.

With a clang, Bai Wushuang pulled out the long sword with cold light from the sword case at his waist.

"For example, my saber. Husband knows its name, Panlonghanyujian." While talking, Bai Wushuang patted the shoulder of Fu Shishuang next door, "And Xiao Shuangshuang, the Mo family you inherited, what's in it?" Moon Chasing Crossbow, Silent Sleeve Arrow, Crescent Moon Flying Knife..."

Li Yunfei "..."

That's obviously because the names of your things are too exaggerated!

Well, in this world where Jianghu martial arts exist, it seems that without a decent name, there is really no style.

"Then call you Wangshu." Li Yunfei looked at the pistol-shaped flintlock in his hand and said, and then looked at the rifle-shaped flintlock on the table in the distance. Xihe"

Wangshu and Xihe are goddesses representing the moon and the sun.

You can choose any educated name, anyway, there are too many such pairwise names in your mind.

According to the size of the firepower, the name is completed. The pistol-type Wangshu is less powerful, and the rifle-type Xihe is definitely the main output at present.

"Eh? Wangshu, Xihe? What's that?"

Not only Bai Wushuang, but also Fu Shishuang and Kong Xiaoliu looked at him curiously at this time, Li Yunfei's heart skipped a beat, forgetting that this world just happens to not have such a myth.

After perfunctory a few times, saying that they represent the goddesses of the moon and the sun, Li Yunfei found out with a headache that several people's eyes were staring. Well, only Bai Wushuang is a star, and the other two are curious. .

Therefore, he can only tell some fairy tales that children can understand.

"Every time I hear my husband's current story, I feel very novel."

"Yunfei is very good at making up stories"

As Bai Wushuang said, Fu Shishuang agreed very much, and although Kong Xiaoliu didn't speak, she also nodded.

Do you really think I am making up a story?

Li Yunfei rolled his eyes, and then went to check the Xihe rifle. The butt made of walnut wood is very textured, and the metallic luster of the gun body is particularly dazzling, and this rifle is surprisingly big!It feels different from his drawings...somewhat different?

But what he cares about now is the metal problem. When he tried the Wangshu pistol just now, Li Yunfei was a little curious.

What kind of metal is this?Some of the touch and appearance were different from the steel he had seen in the villa.

After asking Fu Shishuang, the answer given by the other party was steel mixed with meteorite. ? ? ? ! ! !

"When did we have meteorites?"

"Steel was brought by the people who came to the villa last time. As for the meteorite... there is a sale in the Golden Talisman Garden, but it is very rare, hard to come by, and very expensive."

Fu Shishuang explained that there have been more and more shops in Jinfuyuan recently, and there is a book in the management center of Jinfuyuan that registers the business of each shop. She also went to see it after she had Yunfei's drawings After a quick glance, I found a lot of cast iron shops, and then I collected some precious metals.

Meteorites are hard to come by, but they are not without them. For example, in Jianjian Villa, it is said that there are still a lot of stocks, and these cast iron shops don’t know what kind of way they can get a small amount. The Meteorite Iron, maybe it was brought out by some traitorous disciples?

No matter how it came from, anyway, Fu Shishuang collected meteorites these days. Although he only received a little bit, it was only to the extent that he could be mixed with steel to make a new type of alloy.

Just an experiment, and the resulting new metal is unexpectedly tough!Under the various processing of Mohist utensils, the hand-cast barrel can also withstand very high-intensity damage.

"I see..."

Li Yunfei finished loading the Xihe rifle at this time, the rifle-shaped Xihe caliber is much larger than the Wangshu pistol.

------ Dividing Line No. [-] Mother ------

Mother No. [-]: Ask for a monthly ticket at the beginning of the month!Ask for a ticket~ After reading it, you can read and make the other two books.

The south is getting colder and colder, and the code word feels a cold hand pain

Chapter 775 Gun or cannon?

Chapter 30 The Caliber of the Millimeter... Wait? 30 mm?

Li Yunfei glanced at the data written on the ammunition box, and looked confused. The first blueprint he drew was only a 23mm caliber?How did this get so thick?

"Have you changed the blueprint?"

"Well, the newly cast barrel is much tougher than expected. I have already done experiments. I shot it multiple times in a short period of time. The barrel can perfectly withstand the ammunition of the existing caliber, and the gunpowder equivalent has also been appropriately strengthened."

Li Yunfei looked at Fu Shishuang in a cold sweat, and then his expression became a little serious.

He put down the gun and gave Xiao Shuangshuang a fist with little strength on his head.

"Nonsense! Don't do such dangerous things in the future. Even if you want to try something new, you can spend some money to recruit people to experiment!"

Li Yunfei was really a little anxious, but the worry between the words was obviously conveyed to Fu Shishuang's heart. After being hammered on the head by Yunfei like this, she lowered her head with a blushing face, and then hummed weakly.

"However, if those experimenters are injured or die... we must also give adequate compensation"

What Li Yunfei said was very indifferent, as if he had no human touch, but whether it is ancient or modern, such things are very normal. It is very simple to take people's money and prevent disasters for others. It is a question of whether there is malicious exploitation.

However, in order to have a clear conscience, Li Yunfei naturally wanted to double compensate those who sacrificed their lives for scientific experiments.

After admonishing the little Shuangshuang who was a bit messy, Li Yunfei raised the Xihe rifle again.

To be honest...very heavy, it is more than ten times heavier than the Wangshu pistol, the thick barrel seems to be saying to him, let it spew out flames worthy of the name of the sun goddess!

But... this is a 30mm caliber rifle, Li Yunfei felt a little weak holding it.

This caliber is called a rifle, but he prefers to call it a cannon. After all, according to common sense, once the caliber exceeds 20 mm, it is generally recognized as a cannon.

Barrett's sniper rifle in his previous life was just a 12.7 mm caliber... This reminded him of another sniper rifle.

Qasim's sniper rifle...the caliber is exactly the same as the Xihe rifle in his hand, both are 30mm.

Barrett can penetrate a 800cm thick steel plate at a distance of 1 meters, and a 300cm steel plate at a distance of 1.8 meters. It is considered excellent in the anti-material sniper rifle, and the Qasim sniper rifle is respected as infantry. The cannon is even more perverted, and after the matching hand-crafted exclusive bullets... the Qasim sniper rifle can easily penetrate the tank within 1000 meters!

Of course, although the caliber is the same, Li Yunfei does not think that the Xihe rifle can be compared with the Qasim sniper rifle. After all, the difference in bullets alone prevents them from exerting the same power.

He used round lead bullets, not armor-piercing warheads, and the gunpowder excited may still be a bit inefficient at present, and black powder is also a bit behind. In order to improve efficiency, it may have to be developed in the future. Smokeless gunpowder.

Smokeless gunpowder... just thinking about it feels a little far away, it is something as technically limited as nitroglycerin bombs.

Li Yunfei, the main material needed for smokeless gunpowder, can't make it at all now. It needs nitrocellulose, which is commonly known as nitrocellulose. It needs cellulose and nitric acid to be formed through esterification reaction, and some materials that are difficult to obtain are needed. , like concentrated sulfuric acid and concentrated nitric acid.

These things... Li Yunfei can't get them at all. Even if they want to prepare them, they must build a laboratory with sufficient technology, and he doesn't have the time and effort right now.

The materials and manpower required for the industrial synthesis of concentrated sulfuric acid and concentrated nitric acid are estimated to be found after returning to the villa.

Shaking his head and sighing, the development of science must be done step by step, and no one can eat a big fat man in one bite.

Then, let's try Xihe's power.

Li Yunfei lifted the Xihe rifle. To be honest, this rifle is too big. In order to achieve a caliber of 30 mm and to make the barrel more tough, the side diameter of the barrel is half the size of a fingernail. The weight is also estimated to be forty or fifty catties...

After all, it would take more than a catty to fill it with just one ammunition. A large amount of gunpowder and lead bullets can guarantee its sufficient power.

Now, there are more than three or forty steps away from the big tree that was hit by Wangshu's pistol, which is equivalent to about 40 meters. Li Yunfei aimed at it with the ruler on it.

inhale exhale...

Seeing Li Yunfei's extremely solemn expression again, the three women next to him naturally held their breath and looked at where Li Yunfei was aiming at.

Li Yunfei made up his mind, come on, let the world witness the power of a rifle in the world...

Boom boom boom! ! !

The fire dragon spit out from the muzzle of the gun, and the light, fire and sound erupted almost at the same time.

The moment the trigger was pulled, a large amount of white smoke appeared in front of Li Yunfei's eyes, and he also staggered backwards. The strong recoil made him unable to adapt at all, and then he felt the moment before he fell to the ground. The back is soft.

Bai Wushuang had already caught him, wrapping his arms around him...

Looking at the other person's mouth shape, Li Yunfei couldn't hear it clearly. Just now, the loud sound caused by Xihe's ejaculation caused him, the person closest to him, to have tinnitus.

"Husband? Are you okay?"

Looking down at Li Yunfei in her arms with dazed eyes, Bai Wushuang looked worried. In that brief moment, her husband was almost knocked back to the ground. How could she have the heart to look at the big tree?

"It's...not bad..."

Li Yunfei felt his numb arm, Xihe's rifle had already hit the ground after shooting just now, he forced a smile, and then stood firm with Bai Wushuang's support.

"What's the matter? How powerful is it?"

While talking, Li Yunfei quickly turned his head to where he was aiming.

"Great..."

"Although I don't know what the Mohist's top hidden weapon is, but what you made, Yunfei... may not be able to defend against a master of internal skills, and it can even threaten a grandmaster who takes it lightly..."

Kong Xiaoliu's eyes and pupils shrunk slightly, and the "Physics" in her hand was about to fall off, while Fu Shishuang looked at the big tree in the distance, nodded and spoke seriously.

That big tree... has been pierced through, and there is a big round hole in the trunk, which directly passes through the whole trunk, and then hits the courtyard wall of the mansion farther away, and the courtyard wall made of stone is also A chunk of it shattered, and then the buckshot fell into the yard next door...

------ Dividing Line No. [-] Mother ------

Mother No. [-]: Ask for a monthly ticket at the beginning of the month!Ask for a ticket~ After reading it, you can read and make the other two books.

Historically, the caliber of the flintlock rifle has been 25.4 mm. Let me strengthen it, is it not too much?

Chapter 776 Husband, he started again~!

"What the hell is this..."

Kong Yage's little loli grasped "Physics" firmly again, and her eyes turned directly to Li Yunfei at this time.

This is definitely not something from the Ji family, and she also understands that the Mo family, which is similar to the Ji family, cannot make such a thing.

The hidden weapons of the Ji family and the Mo family also have many powerful hidden weapons, but any powerful hidden weapons that go deep into the back need a certain amount of internal energy to activate them. In other words, the condition for using a powerful hidden weapon is that you must at least be Famous warriors.

Only by wrapping the hidden weapon with inner qi can the power of the hidden weapon be strengthened, and the same is true for the concealed weapon of the mechanical type, sometimes it needs inner qi to stimulate it to achieve continuous continuous attacks.

Otherwise, with hidden weapons alone, why would ordinary people fight warriors?

And yet... what did she see?

That is definitely a powerful 'hidden weapon'. Although it may not be able to defeat the grand master, it can definitely deal with internal skill masters!It is several times stronger than the previous Wangshu who was a little smaller!

And...you don't need a little internal energy to stimulate it!
