Following behind Xiao Bai, Ning Fei also found that the pressure generated by that yin qi suddenly disappeared.

Chen Tianzhen was also full of calmness and did not have any discomfort, which also made him breathe a sigh of relief.

Xiaobai's pace has quickened a lot, and Ning Fei and Chen Tianzhen's pace has also accelerated a lot.

When he arrived at the stone gate, Xiaobai suddenly stopped.

"Go in by yourselves, I can't go in." Xiaobai said, "After a month, no matter what the result is, you must come out, if you are still in meditation at that time, I will come in and wake you up." ”

"Well, I can grasp the time." Ning Fei said with a smile.

"Tell you again, after you go in, don't talk, don't move, find a place to sit down, and start cultivating, the aura inside is not comparable to the outside, as long as your strength is enough, there is a great possibility of breaking through, and after entering, you will take out the spirit bead on your body and put it between the two of you." Xiaobai said.

Ning Fei was a little curious: "What does this have to do with the Spirit Bead?" ”

"If you don't have a spirit bead, you can cultivate directly in it, and the yin qi will rush into your body, and when the time comes, it will make you go mad, and this is also a creation for your spirit bead." When Xiaobai said this, he didn't continue, he stretched out his hand and opened the stone door.

The thousand-pound stone door is like a wooden door in Xiaobai's hands, and Ning Fei and Chen Tianzhen can also do it.

However, Xiaobai's next change made them gasp.

They could all clearly feel that the aura in Xiao Bai's body suddenly became chaotic, and his face became more and more pale, as if the stone door was absorbing the aura in his body at this time.

Ning Fei just wanted to ask, but was stopped by Xiao Bai with a look, and then his eyes skimmed, signaling the two to hurry in.

Ning Fei and Chen Tianzhen took a deep breath, and the two of them didn't ink, and hurriedly walked into the stone gate.

Now, they understand why Xiaobai can't come in, and if they want to open this stone door, they need to pay a certain price! I don't know if Xiaobai will be able to recover after a month.

As soon as the two of them entered, the stone door closed.

Xiao Bai outside breathed a long sigh of relief, sat on the ground, wiped the beads of sweat from his head, and took a big breath of air.

"What can be done, it depends on your creation, two boys, I have been out of the way this time, and I can only help you get here." With that, he immediately sat cross-legged again and began to regain the aura in his body......

When Ning Fei and Chen Tianzhen walked into the stone gate, the expressions on their faces became a little exciting.

The space behind the stone gate is so large that it looks like an underground palace.

Ning Fei bet that this place was definitely bigger than the tomb of Kublai Khan that he had visited before.

Moreover, as soon as the stone door was closed, the two of them felt the change.

It's as if the whole person is soaking in a hot spring, and there is an indescribable ease all over the body.

That's Reiki!

The two glanced at each other, and they both saw the surprise in each other's eyes, before Xiaobai said that the aura in this was very pure and rich, Ning Fei was only half-convinced, after all, Tiandao's aura was already abundant to a certain extent, otherwise, they would not have been able to have such a change in four years.

If it was on Earth, Ning Fei didn't know if he would be able to break through to the Yellow Dragon Realm in his life.

Now, he's feeling different again.

If you have to make a comparison, this inside and outside is equivalent to the difference between Tiandao and Earth.

Ning Fei suddenly felt that the earth's environment was simply to a certain extent!

It's just that he is also a little curious, how many years ago, what happened to cause the earth's aura to be close to exhaustion?

With Xiaobai's advice before, Ning Fei and Chen Tianzhen didn't dare to have any conversation, and everything could only be made with eye contact.

As far as the eye can see, there is no edge in sight, so it will be called the underground palace for the time being.

In front of them, there was a corridor, and they didn't know how long it was.

Finally, under eye contact, Ning Fei and Chen Tianzhen walked forward together.

With every step forward, Ning Fei could feel that the aura seemed to be abundant.

This made the faces of both of them show excited expressions, originally they thought that the previous aura was already very pure and abundant, but they didn't expect that it was just the beginning.

Keep going!

Whether it was Ning Fei or Chen Tianzhen, they all thought so in their heads.

Although they also wanted to find a place to sit down and cultivate immediately, if the aura became more and more abundant, the possibility of them being able to break through was naturally greater.

Therefore, in order for them to break through, they must go a certain distance ahead, and at this time they have already thought about it, if they really encounter any trouble, they will withdraw immediately, so as not to cause any problems.

That's what they thought in their hearts, and they really planned to do it.

This corridor was almost impossible to walk, and it took almost ten minutes to walk, and in the end, the two of them still couldn't see their heads.

"It's weird, is this still a formation?" Ning Fei thought in his heart, and he didn't dare to speak, but then he overturned his previous thoughts, now this is definitely not a formation, after all, the richness of the aura can't be faked, if they really haven't gone far, how can they feel the change in the aura? Therefore, he was sure that he and Chen Tianzhen were definitely not standing still.

"Keep going!" Ning Fei made up his mind and quickened his pace, and Chen Tianzhen naturally hurried to follow.

After walking for about ten minutes, the two finally stopped.

This corridor can be regarded as coming to an end.

Although the two were not so tired that they were sweating profusely, they were still a little depressed.

This corridor is too long, isn't it?

They turned their faces, and the terrain was much more open. And the scene in front of them made their eyes widen. Chen Tianzhen was about to exclaim, but fortunately, he closed his mouth in time, so he didn't make a sound.

In front of them, there were nine coffins horizontally, and the position was also very unique, and it seemed to have a certain degree of exquisiteness, although Ning Fei had accepted the inheritance of the magic circle, but now he was only at the entry level, and it was still a little difficult for him to see the doorway.

Suddenly, Chen Tianzhen stretched out his hand and pulled him, Ning Fei turned his face and found that Chen Tianzhen had a look of understanding.

Ning Fei was still a little confused at first, but now he also understood. It seems that Chen Tian really knows some ways.

Chen Tianzhen wrote a few words on Ning Fei's palm, and after the last word was written, Ning Fei's eyes lit up.

"Hide from the sky!" He thought of these three words in his heart, and almost didn't jump up directly.

Even if he relieved the emotions in his heart, his body trembled a little because of the excitement.

There are nine levels of magic circles, and the nine levels of the big array are enough to cover the sky and the sun!

This Concealment Array, but it also belongs to the ninth-rank Great Array, if you want to arrange such a formation, not only does you need aura, but more importantly, you need the strength of Feng Shui's art of public opinion, at least Ning Fei doesn't have such strength now.

Although Ning Fei could only arrange a third- or fourth-rank magic array at most, this did not mean that he had no understanding of the ninth-rank array!

It's like a person can only afford a car of 100,200,000 yuan, but he will still go to see millions of cars.

Concealing the sky, just the word "concealing the sky" is enough to make everyone tremble.

As Xiaobai said, now Zhang Zhenren and the others are still alive, just recovering the aura and primordial spirit in their bodies, so now they have no way to cross the catastrophe at all, the only way is to lay down this Concealment Array, and only this Concealment Array can avoid the Heavenly Machine, continue to recover, and do not need to go to the catastrophe.

"It's a big deal!" Ning Fei thought to himself, and his eyes also looked around.

On the top of the cave, there is an iron chain as thick as an adult's arm, and the iron chain is covered with talismans, which are hung on nine coffins, and at the top of the cave, there are seven night pearls, corresponding to the seven stars of the Big Dipper in the sky.

And on the edge of the seven night pearls, there are two golden pearls, which are the two hidden stars on the edge of the Big Dipper.

The Big Dipper, there is also a saying, called the Big Dipper, which is seven hidden and two appear, and the other two are auxiliary stars and Bi stars.

Those two gold beads correspond to the two hidden stars.

Therefore, it is not an exaggeration for Ning Fei to call it a big deal, think about it carefully, in this world, apart from Zhang Zhenren who can still have the strength to arrange such a formation, Ning Fei can't think of anyone else.

"That's not right!" Ning Fei suddenly remembered something in his mind.

You must know that if you want to arrange the Concealment Array, it is not just enough cultivation ability, it also takes time, could it be that before this, Zhang Zhenren had already realized that something like that would happen, so he arranged everything in advance?

Thinking of this, Ning Fei's mind was about to explode, if it was really what he thought, if Zhang Zhenren really knew that the Buck people would suddenly betray them, why didn't he prevent it early, but instead set up such a formation?

I can't figure it out, even if he is giving Ning Fei a brain, I'm afraid he won't be able to figure out the reason.

Ning Fei had an idea, but he wasn't sure that Zhang Zhenren might really have calculated it, but he also understood that the way of heaven was irreversible, so he could only think of other ways.

Ning Fei glanced at Chen Tianzhen, and the two sat cross-legged.

Immediately, Ning Fei took out the spirit bead in his pocket and put it between the two of them, and then began to close his eyes, run the spiritual energy in his body, and began to race against time to cultivate, after all, the two of them only have a month's time, this time is not long, it is not short, no one knows what the final result will be, so they can only fight.

As long as they put in the effort, the final result is actually no longer so important, after all, they have done what they should do, and they have worked hard when they should have worked hard.

What Ning Fei and Chen Tianzhen didn't know was that when they were cultivating, the nine beads corresponding to the Nine Stars of the Big Dipper on the top of their heads suddenly emitted a ray of light at this time, and they immediately began to rotate slowly, like a Dou Zhuan Star moving......

After a long time, the light of the nine beads suddenly converged, and in an instant, it directly turned into a pillar of light and threw itself into the top of Ning Fei's head.

And Ning Fei, who was in a state of settling, trembled violently as if his body had been shocked, and a light flashed on the Yin Hall, becoming brighter and brighter.

"it!" Ning Fei himself was also taken aback, he suddenly opened his eyes, his face was extremely ugly.

A mysterious energy suddenly rushed into his body, and it was desperately moving, it was difficult to suppress it, and there was even a faint possibility of blowing up the body meridians.

"Damn, how many dogs have I had in my last life, and retribution has come in this life?" Ning Fei gritted his teeth, even though the pain in his body was incomparable, he didn't dare to make the slightest sound, so that Chen Tianzhen, who was sitting in front of him, was unaware of everything......
