The electromagnetic cannon is quite interesting because of its prerequisite advantage in definition.

It's just that the shells suitable for the use of electromagnetic guns, and the shells used by conventional artillery, cannot be used.

If the shells of gunpowder cannons, which have been developed for nearly a thousand years and have already achieved a perfect system, are used in electromagnetic guns, they will inevitably have a number of fatal defects, such as the inability to accurately guide, and the lack of decisive advantages in relative lethality over weapons of the same level......

In order to compensate for these shortcomings, the shells of the electromagnetic cannon must be made of special metals that can isolate the EMP position brought by the super electromagnetic cannon and are not melted by the super high-frequency electromagnetic waves. This extravagant range of materials is the biggest problem that limits the popularity of super-electromagnetic guns.

If we fail to solve the cost inflation caused by this problem, the cost performance will inevitably block the development of this cutting-edge weapon forever.

The railgun, which uses electromagnetic power as a launch aid, is indeed an expedient measure when the problem is not solved.

Of course, there are some areas where these problems don't seem to be a problem......

Even......

"After all, you still want to say that the super electromagnetic cannon should not be considered for mass production at all, but only the elite of the ace troops with full ability are suitable for equipping!" Nanase, who was carried on Xiao Moumou's back, suddenly said: "The Heavenly Book World has the ability to manufacture qualified shells at low cost. Even the GN Gundam units that have turned on the ability to quantize can be 3D printed after downloading the molecular formula......"

snapped, but Xiao Hong slapped a protrusion on Nanase on his shoulder, interrupting her speech.

"Don't give up yet, we only have one Chise-chan, she has more important things to do, and it's not called a high cost to let her provide you with shells for that super electromagnetic cannon!?" Xiao Hong said: "There is such a thing as a super electromagnetic cannon, and the self-sufficiency of the quantized troops is enough!" As for those of you who are engaged in research, it is the right way to provide structural drawings honestly! ”

The footsteps were far away.

The space-time gate of the Heavenly Book World was also closed.

……

In the world of suffering, the northeast snowfield, there is a cliff near the sea. This cliff connects the small East China Sea in the north, leans against the burial corpse river, the fog is shrouded all the year round, but there is never rainfall, so at night you can always see a round of bright moon rising from the river surface of the wonder, called Qianjiangyue.

While this plot is happening gradually, a black-robed red-haired underworld killer Matt runs all the way at the foot of the mountain. "Yuan'er, Yuan'er, I'm Shuanglong's back, are you there?" The red-haired brother began to shout loudly at the intersection: "Oh no, something big has happened!" ”

Yuan'er, also known as Pan Mengyuan, is the daughter of Long Mojiu and Heartstrings, and the only heir of the Nine Dragons and the Mermaid Clan in the Dust Realm.

Pan Mengyuan died when he was a child and was raised by his three fathers.

She is talented and has strong learning ability, but because of her fate, her relatives around her died one after another.

With a miserable background and no relatives, she was finally abducted by Ouyang Shangzhi in the plot a long, long time ago.

At the instigation of Ouyang Shangzhi, Pan Mengyuan gradually lost his true nature, and in order to take revenge on the Syndicate who forced his parents to death, he turned into a female killer Zero, eliminating dissidents for the Ouyang family and killing people in the righteous path......

However, after shedding a bloody road and experiencing various grievances and hatreds, Pan Mengyuan still repented and retired to Xiaodonghai.

And this fashionable young man who came to report the news was a double dragon back.

Ssangyong has no name and no surname, and this title is just a code name.

He was originally a killer of Yishuilou. His personality is stinky and funny, he likes to pretend to be cool and handsome, and he even criticizes his speech.

In addition, he is also reckless and lacks thought, and he doesn't look like a qualified killer no matter how he looks at it. Fortunately, he has one last merit, that is, he treats his friends super righteously, even if he is broken, he can be regarded as a bloody man who values love and righteousness.

Therefore, in the end, he did not succeed as a killer, but became the big brother of the rivers and lakes and an indispensable wonder man in the righteous path of martial arts.

In the story at that time, Shuanglong fell in love at first sight with his back to Zero, and he stalked him, but in order to save Zero from Ouyang Shangzhi's clutches, he joined the Sun-Shooting Group to hunt down the list of characters on the Dongying Black List, and Liucong Tianqi and Ouyang Shangzhi were both assassinated by him......

However, the falling flowers are intentional, the flowing water is ruthless, and Zero has already belonged to his heart, and he can't tolerate others in his heart.

After the end of the Ouyang family, Zero was full of heart, and in order to pay tribute to his parents who died in the burial of the corpse in Jiangjiang, he returned to Qianjiangyue.

After Zero went into hiding, Shuanglongbei also retired, and in an unknown place, he continued to be his gangster, drunk and dreaming of death.

Mmmmmmmm, that's right, the one who was assassinated by Shuanglong's back was the Ouyang Shangzhi that Xiao Moumou has now incarnated!

So now, a peak sword duel between Ouyang Shangzhi and Aoxiao Hongchen shook the entire rivers and lakes and spread quickly.

Naturally, Ssangyongbei will also receive the message.

After getting the news, Shuanglongbei naturally settled his group of gangsters as soon as possible and wanted to re-emerge.

After all, at the beginning, Shuanglongbei and the Ouyang family formed a mortal enmity that was so thick that it could not be dissolved. What's more, there are more zero-related factors in it, and there is no room for Shuanglong's back not to do his best to deal with it!

And the first thing that Shuanglong did when he reappeared in the rivers and lakes was naturally to contact those colleagues who worked together to assassinate Ouyang Shangzhi at the beginning.

However, his eldest brother Su really just died not long ago, and he was soaking in the hot springs to cool down, and the mysterious swordsman Feng disappeared after Su Huan's death, and the ninja master Shenhe Saki had already returned to Dongying, leaving only the contact information, and the Chang Moyi whose body was cold was that the master was actually his father......

Even the Qin Fake Immortals, who were usually running around, couldn't find anyone at this moment.

I couldn't find the back of Shuanglong, who was eager to go down the mountain, and at the top of Cuihuan Mountain, I didn't find that Qu Shitu seemed to have something to say and didn't finish......

At this moment, Shuanglongbei realized that the famous sun-shooting group back then was already yesterday's yellow flower and fell apart!

I couldn't find the back of the double dragon of the same way, so I had to write a letter to the ninja master Shenhe Saki according to the contact information left to explain the reason.

But Shenzuru Saki is far away in the east, and it will take a long time to go and come.

Impatient and reckless on the back of the man, so he held back a momentum of wind and water, made up his mind, and single-handedly embarked on the road to start the terrible journey of assassinating Ouyang Shangzhi alone......

From the Central Plains to Southern Xinjiang, in five days, Shuanglong stepped on all the places where Ouyang Shangzhi might haunt.

But as a result, naturally, nothing was found......

The reason for this is naturally because that Ouyang Shangzhi is pretended to be by our Emperor Hongwu, the first emperor of the Taishang Yuan Emperor of the Aolai Kingdom.

Since it is pretended, the pretending person is not dedicated to running around, so naturally there is no need to find it.

In the vast sea of people, Ouyang Shangzhi's double dragon back could not be found, and he was worried about the situation, so he had to come to Qianjiangyue to confirm it to rest assured. At the same time, you can also discuss the future path with Zero, who has always been smart, and wait for a reply from Crane Saki by the way.

That's why there is a thousand rivers and moons running wildly, and shouting.

As the saying goes, Wangshan runs a dead horse, and the place at this intersection is undoubtedly far away from the top of the cliff of Qianjiangyue.

As a killer, Shuanglongbei's quality is not easy to say, but his strength is undoubtedly top-notch, and he is naturally skilled in hiding tricks such as bunching sound into a line. His shouts were naturally transmitted to the top of the mountain with clarity and clarity.

So the man at the top of the cliff received the summons and let out a sigh.

The familiar sigh made Shuanglong's back begin to hesitate, and a sense of melancholy was out of control.

Looking closely, Shuanglong's back saw that the fog on the cliff had dissipated, the mountains and forests had moved out of the way, and a wild path that had not been seen had taken shape.

After settling down, with a rare sigh, Shuanglong stepped on the trail step by step and appeared on the top of the cliff.

"Brother Shuanglong, you are so anxious, but for the sake of Ouyang Shangzhi's reappearance in the rivers and lakes?" A wisp of white figure, standing quietly on the edge of the cliff, sensed that Shuanglong stepped on the top of the mountain with a calm and relaxed look.

When Shuanglong saw Zero on his back again, he was a little distraught, but when he heard these words, his heart suddenly tightened, and he asked worriedly: "Ah? Yes, yes, it turns out that Ouyang Shangzhi is not dead, not only did he not die, but his skills have improved greatly, and he was on par with Aoxiao Hongchen a few days ago...... Hey? Yuan'er, how do you know? Could it be that Ouyang Shangzhi has already found you? ”

Zero just shook his head.

Then, he replied lightly: "They haven't found me yet." But on that day, I went to the burial corpse river to worship my father, originally, the time was unconsciously at night, but I was awakened by a huge noise in a drowsy state, only to see the vitality of heaven and earth agitated, the burial corpse river and the river muddy, it seems that someone is fighting upstream. Curious, I peeked secretly and found that it was a group of killers besieging a master on the banks of the Burial River......"

What was discovered by Zero was Thanos, the incarnation of Xiao Moumou, cough cough, the evil death of Huang Quan, and the battle with Mei Yingxue. As a landlord, it is inevitable that he will be worried about the fish in the pond, so he naturally wants to go to the rivers and lakes to listen to the wind and understand what happened.

Therefore, Zero naturally listened to the rumors about Ouyang Shangzhi's return to the rivers and lakes.

But there was no news of the fierce fighting on the banks of the river where the corpses were buried, as if what had happened that night was just an illusion.

On the bank of the corpse river, Huang Quan had a conversation with Mei Yingxue, and Ouyang Shangzhi was also mentioned.

Regarding Ouyang Shangzhi, there is a certain conflict between these two statements.

Zero can only vaguely perceive in these conflicts, and there must be a connection between the two.

But what the specific relationship is, she can't say why.

Until today......

After listening to Zero's explanation, Shuanglong breathed a sigh of relief, and finally put his heart on the ground, and finally remembered his intention. So he said, "It's good that they didn't come to you!" I heard that after Ouyang Shangzhi reappeared, my eldest brother was originally going to assassinate Ouyang Shangzhi alone, but I didn't find anyone after walking around the territory of the Ouyang family, so I had to think about it in the long run. I was worried that something would happen to you, so I hurried over to spread the news. Yuan'er, the eldest brother has already sent a letter to Shenhe Saki, I think we should find a place to avoid the limelight first, and wait for Shenzuru Saki to ......"

As soon as Shuanglong finished speaking, Zero couldn't help but be taken aback, and looked at Shuanglong's back dumbfounded.

Shuanglongbei asked Zero: "Yuan'er, what's wrong with you?" ”

Zero was surprised and asked rhetorically, "Huh? Brother Shuanglong, you have to assassinate Ouyang Shangzhi alone......"

Shuanglong listened to it, and couldn't help but feel empty, and the next moment he was very proud to show off: "That's natural, the man said yes, the promised thing was not done, and now it needs to be remedied, so he didn't say a word, but unfortunately the original brothers couldn't be contacted, so they had to go alone!" ”

Zero asked again: "You also went to the territory of the Ouyang family for a walk, but you didn't meet anyone?" ”

Ssangyong heard the words and nodded yes.

Zero couldn't help but have nothing to say, his body shook weakly for a few moments, and then he held his forehead with his hand and sighed: "Hey, my good big brother, alas, it's really not okay if no one takes care of you, you can poke a hole in the sky, no wonder your master really picked on the picks and disbanded you as soon as he left......"

After listening to Shuanglongbei, he laughed a few times, only as if Zero was praising him, he shrugged his shoulders and replied: "Haha, Yuan'er, I'm not that good at big brother, now time is pressing, don't talk that nonsense, hurry up and pack up your things and find a place to avoid the limelight with big brother......"

Zero didn't move, shook his head, and with a move he grabbed the weapon that had been away from the inner room for a long time, and drew his sword out of its sheath.

After that, she said quite calmly: "Big brother, I'm afraid we won't be able to leave!" ”

It's a pity that the Divine Soldier Wudao didn't have a chance to show its sharpness.

As soon as the zero voice fell, a loud laugh roared under the moon of Qianjiang: "Hahahahahahahaha ”

The familiar tone and voice made Zero's face pale, as if he was recalling the long past that he could not look back on.

"Who is it?" When Ssangyong heard this, he also shouted angrily. He has understood the fact that he was being followed and put his favorite little sister in danger, and he can't help but feel annoyed and regretful about it, but more resentful. The furious Shuanglong pushed Zero behind him and shouted: "Yuan'er, you go first, I'll take it!" After saying that, he was already rushing out with two guns in hand.

But the voice had already appeared behind him.

"Hahahaha, who am I?" A strange magic mirror behind Shuanglongbei has appeared in front of Zero: "I am the Hidden Mirror Man, and the leader of all evils is also: Shuanglongbei, your memory is too bad, it's time to increase your memory!" ”

The magic mirror fell to the ground, and three Xuanbing fingerprints appeared on the ground, which were the symbols of the Ouyang family, which were prominent in the past.

Zero's brow furrowed.

To be honest, both under the Ouyang family, there is not much intersection between Zero and the Tibetan Mirror people.

When Zero became a killer and served the Ouyang family as one of the core forces of the Ouyang family, the Tibetan Mirror people had already formed a gang to break away from the Ouyang family's power in order to realize their ambition of dominating southern Xinjiang. But before Zero came out of the mountain, there were Ouyang Shangzhi, Yu Wentian, and naturally Ouyang Shangzhi's chief manager Zangjingren......

Although the strength of the Hidden Mirror people covers a layer of heaven in the hearts of the past years.

But now, Zero has the self-confidence of not being afraid of people who hide the mirror.

It's a pity that just as she was about to swing her knife to attack, the back of the double dragon that rushed out had already fallen in at a faster speed!

This is not a return blow that finds the enemy running behind you, but !!!!

Zero's face began to look pale.

It was a fleeting sword light, dragging a cyan figure and dragging a sharp sonic boom, as if it was slow and fast, close to the end of the world, from the edge of the sky to the front. What's more, before the sword light was gone, there was already a sound of sheathing, and there was no doubt that the person who came had already collected the sword.

But that strange sword light went straight forward, but it could be caught off guard, instantly cutting the seventy-two most painful acupoints around Shuanglong's back.

Fortunately, the person who came did not mean to hurt anyone, and the seventy-two sword marks of this sword were all superficial flesh wounds, and they would not leave any aftermath.

However, it also directly made Shuanglong's back scream in an instant because of the sudden series of severe pain, and fainted on the spot.

Immediately afterwards, Shuanglong's back was kicked away by someone and landed under the Tibetan Mirror Man.

A spinning slash in the air, it is really not an ordinary swordsmanship, it is worthy of the swordsmanship of stunts and the light skill of swordsmanship!

The figure of the person who came settled down, revealing a more familiar old man in green shirts, who was the fastest sword in the world in the past, the single-edged sword Venerable Yuwentian.

I saw Yu Wentian smirk, rubbing the dust on the back of Shuanglong on the ground, and then he spoke, "Ha, I have to be a good apprentice, let's put down my weapon and arrest it!" ”

In an instant, the door of the house had been blocked by the two masters, and Ling Qiang calmed down and asked, "What are you going to do?" ”

Yu Wentian sneered: "What are you doing?" Hmph, good boy, it's naturally a serious matter: how about returning to the Ouyang family! ”

The Tibetan mirror man waved his hand and stopped Yu Wentian: "Hmph, it's no longer the Ouyang family, it's now the Ao Lai Kingdom......"

Zero Leng snorted and replied, "Only one person may not be able to defeat me; Even if there are two of them, they may not be able to keep me."

The Hidden Mirror Man sneered again: "Haha, we don't need to keep you, we just need to keep him!" ”

Speaking of this, the Hidden Mirror Man stared at the blade in Zero's hand.

The weapon in Zero's hand is called Wudao. After Zero became the female killer of the Ouyang family, Ouyang Shangzhi made the first-line student who was his righteous son at that time, known as the "world's first craftsman", that is, Qu Shitu, cast it with water-patterned steel.

Its sword body is slender and sturdy, rigid and soft. It is also a one-sided blade, which is incomparably sharp, and can blow hair and break hair. Its shape, like a sword is not a sword, like a knife is not a knife, if it must be said, it can be regarded as a curved single-edged sword: after infusing Yuan Gong, it can also be straightened and wishful.

Therefore, whether it is a sword move or a sword move, you can perform it as you wish.

It is precisely because its sword is biased, there is no fixed track to be found, and it is difficult to guard against, this sword is called Wudao.

At the same time, there is no way, and it also reflects the meaning of "those who hold this sword will not be able to follow the right path".

The Divine Soldier has no way, just with the special water wave perception technique of the Zero Yi Fish Clan, plus Ouyang Shangzhi's various swordsmanship, as well as the single-edged sword technique of Yuwentian, as well as the Ming Swordsmanship Rulai Sword Ring and other famous martial arts, and so on.
