On the Yuhua Star, the crowd is crowded, but it is orderly, and the endless lights make the Yuhua Star as bright as a small star.

Because of the Centennial Trade Conference, Yuhuaxing is becoming more and more prosperous, and it is the first black market here in the Pingxing constellation, and now it has gathered merchants from all over the world and monks from all over the world.

But on the other hand, because of the matter of Evergreen Star, coupled with the appearance of the rail cannon, Yuhuaxing is also heavily guarded here, and there are masters and troops stationed in many places, and less than 20% of the entire Yuhuaxing is open to the public. More transactions are placed directly in the stars.

In the surrounding starry sky, there are several simple platforms, which can be regarded as alternative spaceships, with a diameter of hundreds of kilometers, with weak power, but flat on both sides, and artificial gravity formed by formations, which can be traded here.

A little farther away, there is a life planet with a diameter of about 15,000 kilometers, the spaceships above the planet shuttle endlessly, between the planet and space, there are masters out of thin air, there are starry sky monster mounts shuttling back and forth, of course, there are less sword lights, sword shadows, and magic weapons that do not cross the void.

The Centennial Trade Conference has not officially begun, but the deals have already begun.

However, the high-level leaders of Yuhuaxing, the organizer of the conference, gathered together at this time, and in the center of them were three guide rail guns.

And the star lord of Yuhuaxing is a middle-aged person with a somewhat pale and unkempt appearance. This person is the master who commented on Xiang Qingchen when he watched Evergreen Star was blown up before.

This is the star lord of Yuhuaxing, the road name Yuhuazi.

After that time, Yu Huazi purchased a lot of rail guns and several warships of the Ocean Group through various means.

At present, some of these three rail guns were dismantled from the battleships of the Ocean Group, some were produced by the Golden Eagle Empire, and some were purchased from the United Nations caravans.

After several months of research, the senior management of Yuhuazi and Yuhuaxing finally had an eyebrow for this technology.

A master dressed in short clothes said thoughtfully: "Amazing technology! Although the technology is still relatively low-level, it is the use of these relatively low-level techniques that can produce a power comparable to that of the immortals' full strength."

Think about such an attack, when thousands are overwhelming, let alone a single battle star, even if it is a real immortal palace, it can't be stopped!

The only problem is that the rail cannon is too big, often hundreds of meters long, and the energy supply system is complicated, making this thing unportable. ”

Yu Huazi nodded, "At present, it can be seen from the technology of these three rail guns that the rail guns on the Dayang Group warships have the best technology, but they are the most difficult to understand. The Golden Eagle Empire's production, the kind of technology that we don't understand, has decreased, and a large number of means of formation refining have been added. And the one purchased from the United Nations is somewhere in between.

Of the three rails, the Ocean Group is the most powerful and can reach 0.16 times the speed of light, while the Golden Eagle Empire's is barely close to 0.14 times the speed of light, and the United Nations' is about 0.15 times the speed of light.

It is already rare to be able to use some low-level technology, or even technology that cannot reach the realm of returning to the truth, to create such a powerful weapon. ”

Someone else asked, "Star Lord, can we use the formation and refining methods of the Void Realm to create a small rail cannon?"

"Difficult!" Yu Huazi shook his head slightly, his face was full of solemnity and thought, "The core part of this rail cannon is the electromagnetic system. In order for an electromagnetic system to be effective, it needs enough space. This alone doomed the rail gun to be unable to be miniaturized.

Of course, I've also heard that the Ocean Group has weapons such as rail guns for mechs and melee combat, but those weapons are not very effective and useless for the Void Realm. ”

"But we can use the space formation to reduce the length of the rail cannon?"

Yu Huazi shook his head again: "The rail cannon has unimaginable recoil, forget it, you can study it yourself." The technical details of the rail cannon are all here, let's copy them. ”

"Tsk, this Dayang Group is really caring, selling equipment and sending technology. Someone sighed.

Yuhuazi listened and sighed slightly: "Dayang Group...... It's not easy, struggling in the cracks, and there aren't many options. However, even if the technology of the Ocean Group is given to us, it will not be of much use for the time being.

But this rail cannon ...... Tsk, that's a problem!

Mo Qianshan. ”

"Star Lord. Mo Qianshan came out of the corner, and he didn't know where he was hiding just now.

Yu Huazi looked at the rail cannon with his eyes, and said leisurely: "Mo Qianshan, you have to work hard next." From now on, your vigilance extends to ...... Light years or more.

The advent of the rail cannon has given us a big problem. ”

"Understood. Mo Qianshan replied calmly.

The effective range of the rail gun is said to be thousands of light-years away, especially since this thing is still matte, does not emit light or reflects, is fast, and the system is still very small, almost impossible to find. Such weapons have put forward completely new requirements for the defense and vigilance of all sides.

Fortunately, the rail cannon is slow. Even the best rail gun of the Ocean Group is currently only 0.16 light speed.

No, Mo Qianshan put forward an idea: "Star Lord, I think we should make full use of the advantages of my refining weapons and formations to make a kind of vigilance facility."

This alert setup is not a defense, it can be a very weak, but very wide energy layer, which we can detect once a railgun passes through. Although the rail cannon is very powerful, if it is detected in advance, we have a way to intercept it. ”

Yu Huazi groaned slightly, and nodded slowly: "What you said is good." However, in this case, the cost is not small. To reserve sufficient reaction time and distance, then the warning range must reach at least hundreds of millions of miles. To design a ring of vigilance that envelops such an extent is almost the equivalent of enveloping an entire small galaxy. The amount of energy required is absolutely beyond imagination. ”

"We can borrow the power of the stars. One of the masters spoke, "There will be an accumulated layer of energy on the periphery of the star itself, which may be borrowed. ”

Yu Huazi shook his head: "If you want to use the energy of the stars, it's not that easy. Unless the stars can produce aura or star power, we can't use ordinary light at all.

Well, in a short period of time, be vigilant. Mo Qianshan, you take people to patrol around. ”

"Yes. ”

Mo Qianshan is leaving.

However, at this moment, the entire Yuhua Star suddenly shook.

Yu Huazi's eyes suddenly widened: "Not good!"

Before the voice fell, the person had disappeared, and the next moment Yuhuazi appeared in the sky above Yuhuaxing, looking at the defensive barrier that was burning overhead.

Yuhuaxing was orbiting the star at this time, and in front of Yuhuaxing, that is, in the direction of progress, the defensive barrier was burning.

In the next moment, the defensive enchantment exceeded the limit, cracks appeared, and fist-sized 'fireballs' fell violently, and the surface of Yuhuaxing directly collapsed hundreds of meters, thousands of meters, the houses collapsed, the earth collapsed, and the broken wreckage flew all over the sky.

Fortunately, the defensive barrier has been strengthened.

"Guide, rail, cannon!!" Yu Huazi almost squeezed out these three words from between his teeth.

He didn't expect it!

I didn't expect someone to dare to attack me, I didn't expect to attack at the Centennial Trade Conference, I didn't expect the enemy to come so quickly!

Yu Huazi thought that he might be attacked, so he asked Mo Qianshan to take people to patrol around. But in his vision, the enemy would have to wait until after the trade conference was over.

It's normal for Yuhuaxing to have enemies, which black market has no enemies. But even revenge should be after the trade conference, right?

But soon Yuhuazi figured it out - yes, he thought so, so it was natural for the enemy to take the opportunity to sneak attack!

Without having time to think about it, Yu Huazi roared angrily and inspired Yu Huaxing to defend more, and at the same time ordered Yu Huaxing to deviate from the current direction of progress and start to rotate. By rotating, the already damaged defense is replaced.

Fortunately, this time the number of attacks from the rail guns was not large, only a hundred and ten.

Many masters of Yuhuaxing rushed out of Yuhuaxing angrily, they formed a formation in the void, ready to do everything they could to block the Void's rail cannons, and even more masters teleported forward, ready to probe the enemy.

But before Yuhuaxing could explore the information, someone had already sent back the news in front of him - it was the 'Lonely Island Star'!

"Lonely Island Star!" Yu Huazi's face instantly darkened, and he was also solemn. If Yuhuaxing is the largest black market, then the islanding is recognized as the second oldest in 10,000 years.

However, although the name of 'the second in ten thousand years' is not good, it can rank second among many black markets, and it has not been shaken for tens of thousands of years, and there is no need to say much about ability.

Some people even believe that in fact, the island-based combat ability has surpassed Yuhuaxing.

It's just that Yu Huaxing is good at refining weapons, formations, etc., has a wide network of people, rich wealth, and more affiliated and directly subordinate caravans, mercenaries, and even shady pirate groups.

In contrast, Gudao Star is worthy of the word 'island', and there is not much foreign exchange, which can be said to be the bottom of the 12 major black markets. But in a relatively closed environment, the Lonely Island Star can still be the second in 10,000 years, so you can imagine how effective the Lonely Island Star is.

The most important thing is that because there is relatively little communication with the outside world, it leads to a more united interior of the Lonely Island Star, and the outside world is almost impenetrable, and everyone knows very little about the interior of the Lonely Island Star.

In addition, the Lonely Island Star is also known as the 'black market within the black market' - it is more dangerous, but the treasures and riches are also more dazzling, and most importantly, the pirates are open here, and there is no need to use any merchant groups or mercenary groups to hide their identities!

Compared with other black markets, this place is more direct, and people can vent their **, madness, and greed unscrupulously......

Now, the second in 10,000 years of the Lonely Island Star is here, and there is news from the front that the battle star of the Lonely Island Star is less than 30 million kilometers away from Yuhua Star.

There was chaos and busyness on the Yuhua Star;

And the parties around who are preparing for the centennial trade conference are even more chaotic.

No one could have imagined that a war would break out!

After Evergreen Star, Yuhuaxing became the target of the second rail cannon lock!
