This kilogram may be a lot for other rare materials, but for the extremely dense metal of Lingma black gold crystals, it can only be described as much, and a kilogram of Lingma black gold crystals is only the size of a soybean grain if calculated according to the volume, but even so, Gu Mochou still stared at his eyes excitedly.

"A kilogram of Lingma black gold crystals? Not a lot! Not a lot! No, no, no! I'm not trying to bring all of your Lingma Black Gold Crystals, I mean, you just need to give me five hundred grams, oh no! If you are willing to take out 300 grams of Lingma black gold crystals, I am willing to give you all the Pinggu Huangquite on my body, well, I have about 300 kilograms of Pinggu Huangquite, if you think it is not enough, I am also willing to buy some Pinggu Huangquite for you alone, you think this is okay, right? ”

Gu Mochou was already a little incoherent with excitement, at this time, she couldn't think about what Wu Song wanted those Pinggu Huangquite stones for, those Pinggu Huangquite stones were not difficult for her to get, but this Lingma black gold crystal was quite difficult to start.

Although Gu Mochou is a master-level spirit master, it is not so easy to get Lingma black gold crystals, this time to participate in the exchange conference, Gu Mochou also plans to exchange some Lingma black gold crystals if she has the opportunity, originally she was ready for heavy bleeding, but in the end, what she never expected was that she would finally obtain Lingma black gold crystals in this way.

This kind of exchange is obviously a very happy thing for Gu Mochou, exchanging bargains for rare goods is quite cost-effective in the eyes of many people, but for Wu Song, it is obviously a very happy thing to get so much Huangshi, the Lingma black gold crystals the size of soybean grains are not very useful for Wu Song, but a lot of Huangshi solves a piece of his heart disease, with these Huangshi, a lot of Yin-Yang techniques can be reproduced, which is quite helpful for Wu Song.

In exchange for a large number of Huangshi here in Gu Mochou, Wu Song was beautified, but what he didn't expect was that in addition to this Huangshi, there was another harvest waiting for him in the hall outside.

"Brother Wu, I found something interesting, I think you should be interested."

When Comrade Xiao Wu was about to lose his interest in this exchange conference, Wang Lanlin suddenly broke in and said this.

"Something I'm interested in? What is that? Wu Song asked inexplicably.

"I can't say a word or two, you can go out and have a look, but that guy wants a lot of things."

"It's okay, then let's ask Brother Wang to lead the way." Wu Song nodded, with his understanding of Wang Lanlin, it was obviously a very important thing for Wang Lanlin to take the initiative to run in to find him.

Wang Lanlin took Wu Song to the hall, under the guidance of Wang Lanlin, Wu Song got acquainted with an old man named Sun Yaokai, after a few people exchanged greetings for a while, Wang Lanlin asked the other party to take out the things, the old man nodded, led the two to the corner, and then took out a thumb-thick, palm-sized black sheet and handed it to Wu Song.

"What is this?" Wu Song's first reaction when he saw the small piece of black sheet in his hand that was a piece of black sheet with a fight with the fried steamed bread slices was stunned, he couldn't think of what it was, and when he took the black sheet into his hand, Wu Song was stunned again.

Originally, he saw that this thing was shining metallicly under the light, and thought it was a piece of metal material, but after he took the thing into his hand, Wu Song found that this root was not a metal material, and the black sheet felt lighter than foam after he started it, and just when he was speculating in his heart what this thing was, he heard Master Sun Yaokai smile and say, "Master Wu, you can try the hardness of this thing." ”

"Hardness?" Wu Song's head flashed with inspiration, as if he thought of something extremely crucial, he immediately pinched both sides of the black sheet with his two hands, and then used enough strength to break it upward, but his hand hurt, but the black plate did not even change its shape.

"This thing is so hard." Wu Song couldn't help but be taken aback by breaking it so hard, with his current ability, he used enough strength to break it like this, even the spirit horse black gold that was more than ten times harder than steel was enough to deform, but this black sheet, which was almost weightless, did not change a single bit, this hardness made Wu Song confirm his guess even more, he smiled at Master Sun Yaokai, and asked with some excitement, "Master Sun, can I test this thing in other ways?" ”

"Master Wu, please." That Sun Yaokai smiled and made a casual expression.

After Wu Song used enough strength but failed to break the black sheet, he already had a little idea of what the black plate was in his head, this guy thought about it, and then took out the assassination short sword, he used the blade of the sword to slash the black sheet, this time it finally had some effect, but it was just a small white road that could hardly be seen if he didn't look carefully, Wu Song saw this scene and was more sure of his previous guess.

He put away the assassination short sword, urging the spiritual energy in his body, a small orange-red flame instantly formed on Wu Song's fingertips, Wu Song used the orange-red flame on his fingertips to bake the black sheet for more than ten seconds, and when he put away the orange flame, the thin plate was not the slightest change from before.

"Master Sun's good luck, this is indeed the dragon scales of the Demon Dragon!" After Wu Song put away the flames, he smiled faintly, it can have such hardness, and the ability of the fire kang is so strong, all Wu Song can think of is the demon dragon dragon scales, of course, the powerful fire dragon dragon scales fire resistance is not worse than this demon dragon dragon scales, but the color of the fire dragon dragon scales is red, and the hardness is far inferior to the demon dragon dragon scales.

"Master Wu has good eyesight." Seeing that Wu Song recognized the dragon scales, Sun Yaokai also laughed, he pursed his mouth and lowered his gray beard and asked, "I don't know if Master Wu is interested in this thing?" ”

"Interested! Of course I'm interested! Wu Song didn't hide it, nodded very affirmatively and said, "I have to make some equipment recently, and I do have a demand for dragon scales, but I want a lot of them, I don't know how many dragon scales you have in your hands, Master Sun?" Well, I'm talking about the dragon scales of this kind of demon dragon, and the other dragon scales Wu is not very interested. ”

Hearing Wu Song ask about the number of dragon scales, Sun Yaokai smiled weirdly, then rubbed his fingers on his chin and said, "To be honest, I only have this small piece of broken dragon scales on hand!" ”

"That's all?" Wu Song's eyes narrowed into a slit in an instant, and he stared at Sun Yaokai for half a minute, and then said slowly, "Master Sun, judging from the thickness of this dragon scale, even if there is only one piece, it should be a few square meters in size, Master Sun doesn't want to say that you don't even have a complete piece of dragon scale, right?" ”
