Li Qianqian's beautiful eyes flashed with brilliance.

"Fellow Daoist Qin is indeed knowledgeable and knowledgeable. This object is indeed made from the demonic energy of an outsider demon as its core and combined with some methods to refine it."

Seeing Qin Cheng's quick reply, she also smiled and praised him.

The extraterrestrial demon has long since disappeared in the upper continent, and not many people, even from the Supreme Clan, have seen it.

But Qin Cheng can tell so quickly. Could it be that Qin Cheng is a member of the Supreme Clan?

"We all know that the aura of foreign demons can pollute the heavens and block detection, so the black jade tablet refined with this will have the same effect." Li Qianqian said.

"It's just an outsider demon. It's rare in the world now. Only a few sects have access to this thing. So Qianqian also spent a lot of effort to get this black jade token."

Qin Cheng nodded. The Three-Eyed Demon had told him this before, but he didn't expect that the principle of this black jade card was the same as that of the demon.

"But I'm also a little curious. I haven't done anything yet, and you don't even know if I can help. Just give me such a precious treasure, and you're not afraid that I'll fall out now."

Putting away the black jade sign, Qin Cheng said curiously.

"I, Li Qianqian, am very accurate in judging people. Fellow Daoist Qin is not that kind of person." Li Qianqian said.

"Moreover, there is an activation method in the Black Jade Card. If you want it to fully exert its power, you need the cooperation of the spiritual method. I will give this spiritual method to Fellow Daoist Qin after the matter is completed."

"Let's talk about the price. This thing should be worth a lot of money." Qin Cheng nodded.

Giving him a jade token, but leaving a corresponding spirit and never giving it back, was in line with his impression of Li Qianqian.

"There is no need to buy it. In fact, next, I want fellow Taoist Qin to do me a favor. As long as I can get what I want, this black jade medal will be a thank you gift." Li Qianqian said.

"Then tell me what you want me to do and where the crystal stones that need to be identified are." Qin Cheng said.

"Don't worry, fellow Daoist Qin. I want to see if you can identify this object first."

Li Qianqian nodded, and with a slender command, more than a dozen black spirit ores floated out between the two of them.

Qin Cheng understood, it was time to check his own ability first.

Although they are said to be spiritual ores, they are actually a bit overestimated.

Only extremely rare spiritual energy permeates these stones, which are no different from ordinary stones on the roadside.

If Qin Cheng hadn't reached the level of transcending tribulation and his perception was extremely sharp, he wouldn't have been able to detect the presence of spiritual energy within it.

You can imagine how ordinary these stones are, the kind that no one would pick up if they were lost.

"These are ancient things."

But after carefully observing the shells of these stones, Qin Cheng asked.

I learned a lot about the basics of weapon refining from Fu Tian before, including how to identify spiritual ores.

Fu Tian also specifically mentioned that the spiritual ore may undergo some changes over time due to the special storage location.

Among them, including this black leather shell.

Of course, the reason why Qin Cheng made this judgment was because Li Qianqian could not have nothing to do and throw out some rubbish and stones for him to see.

"Yes, this is indeed an ancient spiritual ore."

Li Qianqian was surprised again when she saw Qin Cheng's calm expression and nodded.

"Fellow Daoist Qin, the crystal I am looking for is called sky crystal. I wonder if you can find one containing this substance among these ancient spiritual ores."

With that said, Li Qianqian took out another stone the size of a pearl and handed it to Qin Cheng.

"Celestial stone?"

Qin Cheng thought for a moment.

Because of Wan Lian Hammer, I know a lot about spiritual ores and have heard about sky crystals, but this is the first time I have seen it with my own eyes.

And the sky crystal contains a holy aura.
