In Mengluo City, the capital of Mengjian Country, there is a huge building near the sea, presenting a spherical shape, like a pearl, there are many tall chimneys in the building that rise vertically outward, and from the shell of the pearl, there are several sewage channels directly connected to the sea.

This is the first sword-casting workshop in the Dream Sword Country, the Imperial Mansion, which brings together the top swordsmiths in the Dream Sword Country, in order to research various new casting techniques and contribute to the improvement of national strength.

As the chief swordsmith of the Dream Sword Country's Imperial Mansion, Liu Dun said that the pressure was high, and he had been working the new long-range sword in recent months.

During several battles with the pirates, according to information from the military, the opposing side seems to have weapons with a very long range.

If it is only one or two, it may be explained that the other party is a sword immortal with a very high realm, but he has been repeatedly frustrated, and the other party obviously has ultra-long-range precision attack ability, so this matter has to be taken seriously.

This shows that among the pirate gangs, there should be a powerful swordsmith.

"My lord, this is the data of the newly developed long-range sword, please take a look."

Sword Forger Bian Dang handed over the data report to Liu Dun's hands, which was as long as thirteen pages, and analyzed and listed the materials, attack distances, sword qi activation range, and usage of the latest model of long-range swords one by one.

In each test, sword immortals from different realms were invited to use it, and the results were certified and recorded in detail, so that the true situation of the sword could be reflected.

"It doesn't look bad, the Sword Immortal of the Eightfold Realm can increase the range to an average of 1.5 kilometers when using it, and the Fivefold Sword Immortal can also smoothly increase the range to 1 kilometer......"

Liu Dun looked at the data inside, his face was a little lighter, it was still a month ago, the Eight Sword Immortals could only reach a range of 1 km using a long-range sword.

In the world, 1 km is also a relatively long value, and the range of 1.4 km is only reached by the right hand of the gods of the Heavenly Sword Kingdom, Tiandao Yuluo.

It is not easy to achieve this level in a month.

Maybe this sword will be able to surprise those who look down on the Dream Sword Kingdom in this year's Sword Sacrifice Ceremony.

Bian Dang analyzed, "The attack distance has increased a lot, but the accuracy is not enough, I think it is because the eyesight has not kept up." ”

Eyesight?

Liu Dunhu glanced at him suspiciously.

Indeed, if the user does not have superior eyesight, they will not be able to accurately hit the target, no matter how long the range of the ranged sword is.

It seems that in the future, we can only find a way to improve the sword qi into a wide shape or a mesh shape when it is agitated, so that the coverage can be increased to make up for the lack of accuracy, but in this way, there are very high requirements for the user's true qi, and it is impossible to use it on a large scale, so I am afraid that I can only form an elite team of the eightfold realm.

Liu Dun sighed, "If you look at it this way, our long-range flying sword should have been developed to the extreme, if the limit of human eyesight is like this, other countries are not much stronger than us." ”

"It should be, sir." Bian Dang agreed.

"Alright, that's it." Liu Dun took off the blackout mask and put it aside, then raised his hand to wipe the sweat from his forehead.

Fang Yu, an apprentice on the side, hurriedly handed over the water glass.

Liu Dun gulped, let out a satisfied burp, and then laughed happily.

The apprentice was a clever young man, with dripping eyes, a big head, and a thin body, like a big turnip.

He looked at Liu Dun and asked tentatively, "This year's sword sacrifice ceremony, I guess you are still participating as a representative, right?" ”

Liu Dun nodded, "His Royal Highness Rin Sakura has appointed, that's why I need this long-range sword, maybe I can bring it back to the Sword Sacrifice Ceremony." ”

In a few days, it will be time for the sword sacrifice ceremony, and at that time, the important people of the thirteen kingdoms will be present.

At that time, the advanced sword-forging achievements of various countries will be displayed, and then this year's sword-forging swordsmiths will be selected.

The Heavenly Sword Kingdom has maintained its hegemony for a hundred years through the Sword Sacrifice Ceremony and the swordsmiths on various rankings, and only through the deployment of a small number of troops in each country, it has maintained its hegemony for a hundred years, and the reason for this is still the technological leadership.

And because of the lack of talents and minerals, the Dream Sword Country is at the bottom of every sword sacrifice ceremony.

Thinking of this, Liu Dun couldn't help but let out a sigh, how good it would be if the Dream Sword Kingdom could have a few more geniuses.

He looked at the beloved disciple beside him, stretched out his hand and touched his head, and encouraged, "Hehe, in fact, if you work a little harder, in three or five years, this seat should be yours." ”

Fang Yu hurriedly said, "How can there be such a possibility, if the apprentice wants to surpass the master, I am afraid that there is no hope in this life." ”

"Nonsense!" Liu Dun said seriously, "If the Dream Sword Kingdom is not as good as the next generation, how can there be hope?" ”

Fang Yu was stunned for a moment, and immediately understood that his master had exhausted his efforts in order to cultivate future swordsmith talents, if his apprentice was still so uncompromising, he would be too disappointed by him.

"I'm sorry Master. The apprentice must work hard and strive to be able to contribute his strength to the Dream Sword Country one day. ”

Hearing him say this, Liu Dun was a little relieved, smiled with relief, and his tone softened a lot, "This is my good apprentice." ”

He took out the Qiankun mirror and looked at the time-

It was already 9 o'clock in the morning, and it was less than an hour before the time agreed with His Royal Highness Rin Sakura to go to the Heavenly Sword Country.

"Lord Biandang!" Liu Dun stood up and ordered, "You help me pick a new long-range sword that is the best cast, and I will take it with me." ”

"Are you going to the sword festival?" Bian Dang looked at him excitedly.

"Yes."

"Then I'll prepare, it's best to keep it!"

After getting the long-range sword that Bian Dang had prepared for him, Liu Dun immediately rushed to the dock of Mengluo City.

Before he got closer, he saw the big cloud sail ship of the Dream Sword Kingdom from a distance, with a big sea dragon rusting on the sail and colorful clouds underneath.

The Dream Sword Country is a country bordering the sea, with the sea dragon as the honor, and the sea dragon embroidered on the flag sail, only the royal family has this qualification.

"My lord, it's not too early, it's time to go!" In the distance, the sword Rin Sakura was waving at him.

Liu Duncheng was terrified, and hurriedly drove the flying sword under his feet faster.

Behind Kenrin Sakura, there were several personal guards, and a vague humanoid figure that could not be seen clearly.

Liu Dun thought to himself, that person should be the sword-forging genius Wei Gong that His Highness mentioned to him every day during this time.

When he boarded the boat and saw the palace, the whole person was stunned for a moment.

Liu Dun didn't expect that the swordsmith who was so valued by Sword Rin Sakura would be so young.

"I've seen Lord Liuton."

A meaningful smile appeared on the corner of Wei Gong's mouth, if it weren't for Jian Rin Sakura telling him in advance, he would almost laugh wildly, this Liu Dun didn't know if he would find gravity.

"Lord Weigong, look up for a long time."
