Those with liquid aura are low-grade spirit stones, and those with true element-level richness are medium-grade spirit stones. Pen, Fun, Pavilion www.biquge.info But these two spirit stones themselves still have certain attributes, so if the spirit root does not meet or cannot be transformed, ordinary monks will not be able to absorb it at all.

The top grade spirit stone, although there is not much difference from the middle grade spirit stone, but it itself does not have any attributes, and any spirit root can directly absorb the aura above, so it is classified as the top grade.

As for the top-grade spirit stone, it is a spirit stone that changes in essence due to quality, and it is infinitely close to the existence of a higher dimension.

No matter who absorbs the spiritual energy contained in it, it can greatly improve the cultivation of the essence and make the body of oneself transform, which is an extremely rare spiritual stone.

On today's earth, the spirit stone can almost be described as extinct, let alone the legendary best spirit stone.

It is precisely because of this that these spirit stones, which were not taken to Zhang Ning's heart, made the eyes of the Xuannu on the side glow under the mask.

Xuannu was surprised to take down a piece of fire spirit stone, "I didn't expect that there was a medium-grade spirit stone here, and I just happened to surprise the master when I went back." ”

Wandering around, Zhang Ning found that this place could almost be described as a confined space, but it was very huge, the size of seven or eight giant apes.

"Chief, Chief, look at what we've found, it's the same as the body hair on that monster. ”

At this moment, a middle-aged scientific researcher was holding a very long hair in his hand, which could almost be described as a spear. The trotter came to the side of the Xuannu.

Xuannu nodded faintly, she already knew this, and under the detection of her divine sense, all the items in this confined space had been known to her one by one, and she didn't say much.

"I see, you go back and investigate, this place is the cave of the great ape, this thing is not of much value. ”

The researcher's face froze for a moment before he reacted, and although his rank was not enough, he still knew that the great ape was from this place.

And since they got used to it, they could already vaguely smell a hint of beast in the whole space, although it was very faint, but it could still be felt.

Thinking of this, the researcher's face couldn't help but reddened slightly, and Shanshan retreated there, and began to survey the geology here.

At this time, Zhang Ning walked to a wall and knocked there.

"That's really the case, right?" Zhang Ning muttered to himself.

Suddenly, a strong green light appeared from Zhang Ning's right hand, constantly wrapping around his right arm, the color gradually became more and more intense, and there were circles of formation patterns wrapped around it, which was extraordinarily powerful.

"Not good!" Xuannu was startled, she felt the strong true yuan wrapped around Zhang Ning's right arm at this time.

The two middle-aged men wearing masks also felt stuffy in their chests at this time. They couldn't help but snort and put their hands in front of their chests.

Not to mention the ordinary people who were researchers, they all fell to the ground with pale faces.

Xuannu also hurriedly retreated to the researchers, and with a wave of her right hand, a blue light mask was formed.

Different from Xuannu's imagination, Zhang Ning did not suddenly punch the wall after condensing the energy, but slowly touched the wall with his right arm wrapped in green light.

All of a sudden, the people hiding in the blue light mask couldn't help but look shocked, the wall hundreds of meters high was undulating like a wave at this time because of Zhang Ning's slight touch, and there were mysterious red lines rotating on it.

"This is a ban!" Xuannu's face changed, and she suddenly thought of something in her heart.

And among the crowd, the white-haired old man also pushed the glasses on the bridge of his nose and was amazed there, he had already seen Zhang Ning's strength and magic.

"Is this the ancient wisdom of the force field? I can't imagine that it can form an illusory scene that cannot be distinguished by the naked eye. ”

Soon, Zhang Ning put his hand down and stood there indifferently.

Seeing that she was already safe, the Xuannu also faded the blue light mask, revealing the people she was protecting.

Seeing that Zhang Ning was deep in thought, everyone didn't dare to go and disturb, but Xuannu's silver teeth bit it, and Lianbu moved quickly.

"Senior, did you find anything? Xuannu asked in a low voice.

"Hmm. Zhang Ning, who was thinking about it, subconsciously responded, but forgot to add the old voice, and couldn't help but be shocked and came back to his soul.

When Xuannu heard Zhang Ning's voice answering her, her face was also strange, but fortunately, she was blocked by the mask and did not fluctuate much.

"I won't be discovered. Zhang Ning was nervous in his heart. But the thought of the power he possessed quickly calmed down.

Seeing that the Xuannu didn't make much of a move, he defaulted to the fact that the Xuannu might have misheard it just now.

"I thought about it for a while, and the prohibition placed here has already thought of a way to get out, so you should stand back. Zhang Ning's tone replied to the old man, and he ordered to the Xuannu.

Listening to this familiar voice, the suspicion in the heart of the Xuannu was sealed again, and she said "yes" respectfully and retreated into the crowd again.

At the moment when the Xuannu left, Zhang Ning's hands began to quickly form a series of mysterious formations suspended in the air, flying in all directions, and every place where he landed was a spirit stone glowing with red light.

But soon Zhang Ning's movements stopped.

"It's strange, such a superficial prohibition should have been broken, but it seems that something is missing, what's going on?" Zhang Ning, who was under the green armor, frowned, and unfolded his divine sense to hurriedly scan the wall he was facing.

"I see. Soon, Zhang Ning discovered the problem, turned around and shouted in a majestic and old voice.

"Wait for who moved the spirit stone on the wall just now for me to stand up. ”

Xuannu's face changed, as if she realized something, and hurriedly went to Zhang Ning's side again and asked, "Is there anything wrong with the senior?"

"There is indeed something wrong, the protection of this wall is a very simple mixed prohibition of three talents and four elephants, the main role is to prevent the entry of outsiders and the circulation of air. It doesn't have a strong attack power, but to open it, it needs a specific spirit stone as an array eye, but the spirit stone on it is now missing a piece and can't be opened, of course, I can also forcibly break this wall, but the consequence is that it can no longer be repaired, once there is something wrong outside, it will be very troublesome to finish it at that time. ”

Zhang Ning slowly said all the knowledge he had accumulated during this period of time, and the Xuannu who listened was stunned for a while, although she also touched on this aspect slightly, but it was true that there was not much understanding of the current Chinese inheritance.

"I see, the seniors are really thoughtful, and the juniors just took down a spirit stone improperly. ”

Xuannu respectfully apologized, took out a palm-sized red spirit stone from her arms and placed it in front of Zhang Ning.
