Luo Yu thought to himself that since there was a difference in the purity of this metamorphosis stone, could he use the ability of the mysterious flame to purify the year to calcinate those low-grade metacrystallized stones into high-grade metavalolite powder, so that he could make a lot of money.

After some preparations, Luo Yu began to refine this thing, but the result was a big disappointment for Luo Yu, once the low-level Yuan Stone came into contact with the mysterious flame, it would naturally become natural, which was also what Luo Yu was worried about, this thing was originally used for refining medicine and alchemy, and it would ignite when it caught fire.

After a period of time, Luo Yu gave up the idea of refining the Huayuan Stone, but after killing the black-robed monk last time, Luo Yu once returned to the stone room where the black-robed man was hiding, and carefully checked it, originally wanting to see if the black-robed person had any treasures and elixirs hidden there, but he didn't find anything, but he found a lot of middle-level Huayuan stones in the depths of the stone room.

And after Luo Yu finished healing, he suddenly wanted to try to refine the middle-level transformation stone, maybe the middle-level transformation stone can be successfully refined, after all, he now has a lot of middle-level transformation stones in his hands, but the refining results of these middle-level transformation stones made Luo Yu puzzled, after the calcination of Luo Yu's mysterious flame, although the middle-level transformation stones did not spontaneously combust like the low-level, but for some reason they all turned into this viscous black liquid.

This black liquid Luo Yu is really unheard of, but since it is calcined by this mysterious flame, it should be an extraordinary thing, leave it in the future and look through some ancient books of Xiu Xiuxian to see if you can find out the origin of this thing, if it is really a treasure, but it is not useful in your hand, Luo Yu really does not have a taste in his heart.

Thinking of the treasure, Luo Yu had a flash of inspiration in his mind, and suddenly remembered an object, patted the storage bag, and suddenly a handful of jet-black iron of about three feet appeared in his hand, like a ruler not a ruler, like a sword but not a sword, and the whole body was black and shiny, it was the ancestral thing of the Fang family's 'Black Ming Sword', Luo Yu slowly stroked the sword body with one hand, and his face was full of solemnity.

If Luo Yu said that the black viscous liquid Luo Yu didn't know the origin and had no clue at all, then for this black sword, Luo Yu was extremely sure that this sword was definitely a treasure, and it was extraordinary.

Luo Yu has also used high-temperature fire refining, sharp weapons to chop, this sword has no slightest reaction, if the low-level magic weapon is a strong chopping and slashing is directly broken, this makes Luo Yu even more surprised, you must know that even if the middle-level magic weapon wants to cut off the low-level magic weapon, it is impossible, and Luo Yu still whimsically suspected that this sword is a high-level magic weapon or beyond the high-level magic weapon, that legend is the best magic weapon refined by the great supernatural power of the Yuan Infant Stage! However, after Luo Yu tried it with the fire attribute spiritual power and wind attribute spiritual power in his body, it still didn't work, and this sword couldn't carry spiritual power at all.

But looking at the appearance of this thing, Luo Yu can be sure that it is a rare thing that he does not know yet, and it is also a primitive embryo, which has not been forged in any way, and this kind of treasure, before fully understanding its use, Luo Yu will not use it easily, the reason is very simple, not to mention anything else, even if this black iron is mixed into a little bit into the magic weapon, I am afraid that this magic weapon will immediately become extremely strong and sharp!

"Hey! I still don't know much about the world of cultivating immortals! After I go back this time, I must enter the library hall to take a good look at those classics of cultivating immortals, otherwise the treasures will be placed in front of my eyes, and you won't know how to use them." Luo Yu sighed lowly, then carefully put away the Hei Ming Sword and meditated quietly.

And at this moment, on the top of Dianmu Mountain, in an inconspicuous stone cave, there are seven people sitting cross-legged, secretly discussing something, if Luo Yu sees these seven people, I am afraid he will be surprised, because these seven people are all immortal cultivators in the foundation building period, and one of them is sitting on a gray and white futon in a wide robed middle-aged man, who is Zhou Jin, who has not left Luo Yu for a long time!

"Zhou Daoyou, how are the preparations for the auction, there won't be any problems, right? To be honest, if it weren't for Zhou Daoyou's promise that after the auction is over, he will give each of our six brothers a bottle of 'Baoyuan Dan', the old man really doesn't want to hold any auction in Dimu Mountain, this is too eye-catching, if it attracts some forces that can't afford to offend, then our six brothers are afraid that they will have to return to the Scattered Cultivation Alliance." A horse-faced old man sitting next to Zhou Jin said worriedly.

"Zhou Daoyou, what my third brother said is not unreasonable, if Daoyou auctioned ordinary items, it would be fine, but I heard that the finale of this auction turned out to be the rumored magic weapon refined by ancient monks, this kind of thing Zhou Daoyou also dared to take out the auction, and if it was served, Brother Zhou would not be afraid of attracting those high-level immortal cultivators to snatch it? Or do Daoyou think that once this kind of thing happens, the people you find to protect this thing can keep it. The white-faced old man sitting opposite Zhou Jin suddenly said with a strange face.

"What! Ancient Artifact!"

"Ancient artifacts!"

When the other five old men present heard the word ancient magic weapon, they all looked incredulous, and they all exclaimed in surprise.

"How did Brother Bai know about the sale of ancient artifacts at this auction?" Zhou Jin's face also changed drastically when he heard the word ancient artifact, but he quickly calmed down again, staring at the white-faced old man with his eyes and asking in a deep voice.

"Hehe, listening to Brother Zhou's tone, it seems that the matter of this ancient artifact is really true, as for how Bai Mou found out, I am not afraid to tell you, this is the news from inside your Wanxian Building, in fact, everyone knows in their hearts, how can a big force like your Wanxian Building have no spies from other forces lurking in it, and our Scattered Cultivation Alliance is the same, there are also undercover agents from various forces mixed in it, which must include your Wanxian Building, presumably this, Brother Zhou should know better than me. The white-faced old man ignored Zhou Jin's gloomy gaze at all and said to himself.

"Brother Zhou, if you take an ancient artifact and appear at the auction, aren't you afraid that it will bring death to our Dethroned Wood Mountain!" Seeing that the ancient artifact was true, the horse-faced old man just now couldn't help but immediately ask the person next to him.

It's really unlucky, it was written at 9 o'clock in the morning, I don't know what the hell is going on in this Unicom network, and the network was suddenly cut off, there was really an urge to vomit blood, and I had to run to the Internet café far away, but there is a promise of the outbreak of the three more will not change, even in the Internet café, but also for everyone to code out, I also hope that everyone will see the Tao diligently, collect and vote!
