When Yin Jiu was still in Lingge that year, Lingge Commercial Street was still thriving, and every day there would be a steady stream of rare things sent from all over the mainland to Lingge Commercial Street, on the one hand, it was to do business on the other hand, it was to display and identify, after all, there were many treasures that ordinary businessmen had not seen, and it was at least safer in Lingge Commercial Street, and it was also possible to find people who knew how to ask clearly.

One day, Yin Jiu and Luo Bi went to the street to buy raw materials, and met a private customer in the commercial street, who was walking around the Lingge commercial street with a very special gem, and found a few shops that seemed to want to sell this special gem, but no one paid attention to him for a long time.

This person's actions attracted Luo Bi's attention, and he stepped forward to inquire and learned that this person had stayed in the mountains for a day and night, and ran to see what was going on when he heard movement in the distance, and as a result, he witnessed the picture of two huge wild beasts fighting each other, and was scared half to death and ready to escape, but he didn't expect that the two huge wild beasts finally died together, and the wild beasts were all treasures, so he had the courage to get some benefits from the wild beasts, but he accidentally found that the two wild beasts were fighting for a black gem, and this person didn't see anything special about this gem at that time, but he thought it should be a treasure and put away this gem。

Later, I went to many places and didn't find a buyer, and people who saw it said that this was a special ordinary stone, but this person was also brainless and felt that this must be a treasure, so he didn't lose it and was looking for a buyer.

Luo Bi also felt good after seeing this thing at that time, maybe it was some kind of intuition as a businessman, he spent a hundred taels of silver to buy this thing, the price was not expensive, and showed it to Yin Jiu, Yin Jiu said that this gem was too brittle and could not be used to forge knives at all.

As a result, I put it for a day, and when I got up the next day, Yin Jiu was ready to strike iron, but I found that a piece of fine iron prepared by me the night before was gone, and I thought it might have been a thief, but after an investigation, I didn't find any traces of theft, and although the price of the best fine iron was not cheap, but that thing was dead and heavy, and I had the ability to steal things in Yin Jiu's shop, so I just stole money, and what was the use of stealing a piece of fine iron.

As a result, after careful observation, Yin Jiu found that the black gem seemed to have become larger, at first I thought it was an illusion, and then I took a ruler and carefully lit up the bright party only to find that it had indeed become bigger, Yin Jiu had a bold idea at that time, the night before he put this gem of unknown origin on the fine iron, today the fine iron suddenly disappeared, and the black gem became larger, is it swallowed by this black gem?

But if it is devoured, then why is a large piece of refined iron suddenly gone, and the black gem has not become much bigger, so Yin Jiu is not sure, and then he discussed with Luo Bi, Luo Bi reminded him, asked a friend, and checked some information, and finally determined that this black gem was actually a piece of impure mutant Wanxing iron.

It should be that Wanxing Iron was generated by the influence of some other ore, so it does not look like a normal Wanxing Iron, and the purity content of the real Wanxing Iron is not large, but it inherits the characteristics of Wanxing Iron devouring heaven and earth treasures, but due to the influence of other ores, it does not swallow as simply as Wanxing Iron, forming a strange characteristic of devouring part of the energy.

After testing, at that time, this mutated Wanxing Iron did increase its hardness a lot after devouring the best fine iron, but because of its own low content of Wanxing iron, the shape became very strange, and it was not as "picky" as the real Wanxing Iron, the real Wanxing Iron only eats natural treasures, but this mutated ore will be devoured as long as it encounters slightly better materials, and because there are other ores inside, it is not as difficult to forge and smelt as Wanxing Iron.

I have to say that the individual customer's intuition is very accurate, this is indeed a treasure, if you use it well, you can make a terrifying treasure, but if you use it badly, it will become a waste.

Yin Jiu had never used this gem, he thought about using the devouring property to prepare for his new knife, because so far he had not heard of any royal weapon with the devouring property, after the Huci treasure knife was destroyed, Yin Jiu decided to break through his limit and embark on the road home, and he also took this gem with him at that time.

He hadn't imagined that it would be years later when he used this gem again, but although his breakthrough to the royal weapon had been delayed for a long time, he still waited until this day.

After the Earth Tribulation, the third attribute hidden in this newly minted sword was finally activated, that is, the unique devouring attribute that Yin Jiu created for the new sword with gems.

This knife directly devoured the thunder and lightning wrapped around the knife body, and the earth tribulation thunder turned into an engraved pattern and appeared on the knife body, and the treasure knife fell to the ground, and it did not move in the wind.

Yin Jiu finally smiled and said: "This knife must be a royal weapon, but I don't know the specific grade yet, I have added the original shattered Huci Treasure Knife essence to the blade, so the grade is at least at the high level of human weapons." ”

Luo Tian walked up and looked down at the treasure knife inserted in the ground, unlike the Huci treasure knife, the treasure knife in front of him was very thin but very long, the blade was not wide but the blood groove was very body, it looked like a sword, but it had the arc of a knife.

"I've never seen a knife like this. Luo Tian said.

"I have seen by chance a weapon called the Tang knife in the old era, which looks very different from the traditional wide-backed broadsword used in our era today, how to say it, it looks like it has a very peculiar beauty, although it is very thin but has a frightening feeling, and I also take into account that you have used a sword in recent years, and it may not be suitable for a knife to suddenly change to a knife, this knife is both a knife and a sword, you should not be incompetent when you use it, hehe, give the new knife a name, after the name I will take this knife away, put on the handle, create a scabbard, and rate it。 Yin Jiu said.

Luo Tian looked at the cold and shining sword in front of him and smiled: "I want to take other names, the guy in the blade is not happy, since he inherited the name of the mad sword, then he will take the name of the mad sword, and from now on follow me to the triple heavens, splitting the sun, moon and stars." ”

Ten days later, Yin Jiu sent the perfect state of the mad knife to Luo Tian, the craftsmen of the Japanese village and several nearby villages, hundreds of craftsmen wanted to come and see the legendary royal weapon, for such a craftsman village, it can be said that it is a sensational event to produce a royal weapon, and it will also bring great benefits to these craftsmen.

In the future, you can say that you are from the village of kingsmiths, and the fame and price are not comparable now.

Luo Tian turned out the knife box, opened the box, the black handle scabbard, supplemented by a simple golden ornament, the handle side of the knife is engraved with a golden "demon" word, the simple style is with Luo Tian's mind, he is the demon king of the world, his knife does not need other colors to match, and the only one that can match the demon king of the world is black.

Holding the handle of the knife and pulling it out gently, it made a crisp knife groan, and at the same time, a faint arc beating could be seen, and after it was completely pulled out, it brought out a piece of black light, and the blade continued to emit thunder and lightning, and the knife body didn't know what method Yin Jiu used to be able to engrave the word "crazy knife".

"What grade?" Luo Tian asked.

"I think it's at least a mid-level royal artifact, but I don't think I'm qualified to evaluate my own sword, so I invited the craftsman Wang Heli. ”

As he spoke, Heli walked into the room, and immediately nodded when he saw Luo Tian, Luo Tian glanced at him and said, "You come to see this knife." ”

Heli took the mad knife, his eyes were immediately attracted to the knife, and he wanted to swing it, but he was attacked by the electric light on the knife, and the lightning stabbed his palm, forcing him to put down the knife.

"The machine spirit is very aggressive, and it excludes people other than the two of you to use it, this alone is at least the intermediate grade of the king weapon, three attributes, especially the last one that even I have never heard of of devouring attributes, plus the ultra-high-strength blade, and the other two attributes that can complement you, this knife definitely has the high-level level of the king weapon, but whether it is to the level of the immortal weapon I think it is still a little worse, the legend that the birth of the immortal weapon will cause the resonance of heaven and earth, and even cause disasters in the world, this knife may not have reached that level, but it is already very remarkable, Yin Jiu, I have to say that you have the craftsmanship of the craftsman king level。 "Heli gave a very high rating.
