This underground hall is not very large, and it is not even comparable to the hall of the six-grade energy source of the Shinto Temple.

However, the main hall is very clumsy, and I don't know how many thousands of years it has existed, and every trace is the precipitation of history.

In the center, there was an energy transmission array that didn't look complicated, but when Chu Nan looked closely, he found that it contained the charm of great ingenuity, it looked simple, but it had the essence of the ancient formation.

What made Chu Nan's heart even more excited was that the incomparably pure energy fluctuations, he could be sure that this energy source definitely exceeded the sixth grade.

Just, what about people?

"Are you looking for me?" just then, a voice rang out.

Chu Nan's heart trembled, and when he turned his head to look, he saw that the man in the green robe suddenly appeared in the main hall, staring at him with an interested gaze.

"Yes...... Yes, senior, if it disturbs your old man's house, I'll quit. Chu Nan pulled out a stiff smile.

"Are you fighting the idea of this seven-rank energy source?" said the blue-robed man.

Belch......

"Yes. Chu Nan's heart was full of thoughts, and he admitted it very simply.

"Do you know the formation?" asked the man in the green robe.

"I understand, on this day, I call the first divine vein, and no one dares to call it the first. Chu Nan said confidently, if he realized in his heart, maybe this was his opportunity.

"If you unlock this ancient formation, this seven-grade energy source will be given to you, but if you forcibly take it and cause the slightest damage to this ancient formation, I will extract your soul and refine it for ten thousand years. The blue-robed man said lightly.

Chu Nan nodded yes, he knew that the blue-robed man had his purpose in letting him break the formation, but at this time, he had no way out.

At this time, the man in the green robe didn't see any movement, and Yue Peng, who had been following Chu Nan, suddenly stiffened like a sculpture.

"If you don't untie it for two hours, he dies, and if you don't untie it for four hours, you die. The blue-robed man said lightly.

Chu Nan didn't talk nonsense, he took out the red and blue array flags and landed on the front and back ends of this central array, and immediately, dazzling formation lines appeared from between his phantom fingers.

The man in the green robe looked at him with a strange light, it seems that this kid really has two brushes, maybe he can really break the formation perfectly.

Although this ancient formation is infinitely mysterious, the formation together echoes the principle of heaven and earth and the universe, and it can be counted as the same end.

Now Chu Nan's formation realm has already surpassed the ninth level, and it is in a class of its own.

Half an hour later......

"Po"

With a slight sound, a layer of formation light flickered and then disappeared, and this ancient formation was considered to have broken the first weight.

Chu Nan's forehead was covered with fine beads of sweat, and his energy was highly concentrated.

Soon after, the second layer was perfectly cracked, and only the last layer remained, and an hour had passed.

At this moment, two powerful auras suddenly appeared outside the underground hall.

"Look, God really help us, this old dragon guarding the temple is dead, and the eight-grade energy source really doesn't take any effort to get it. A hoarse voice excited.

"Really, let's get in quickly. Another voice said.

The two middle-aged men flashed into the main hall, and as soon as they entered the main hall, they were all startled, staring at Chu Nan, Yue Peng and the blue-robed man in the hall.

The blue-robed man didn't look at them at all, just paying attention to Chu Nan's progress.

The two middle-aged men are the two deacons of the main peak, both of whom are already in the late stage of the Heavenly God Realm, and they originally wanted to fish in troubled waters, taking advantage of the chaos outside, to take away these eight-grade energy sources.

But the situation in the main hall made the two of them freeze in place, not daring to act rashly.

When there were still a quarter of an hour left before two hours, Chu Nan unlocked the last layer of the formation, and a substantial crystal light rushed up from the central array eye.

And at this moment, the two deacons suddenly moved and wanted to snatch it.

But the two were still in the air, and suddenly they found two headless corpses rushing forward.

In an instant, they realized that it was their own body, and their consciousness had dissipated as the ultimate fear had risen.

"Horn ride"

Chu Nan watched the two huge heads fall to the ground, his eyelids trembled, the Taishen Realm, it was so terrifying, the strength of the late stage of the Heavenly God Realm, he didn't even know how to die.

The blue-robed man walked to the central formation, stretched out his hand and grabbed it, and suddenly, a fist-sized blood crystal was taken out by him.

Looking at the blood crystal in his hand, the blue-robed man's eyes showed emotional fluctuations for the first time, and it looked extremely complicated.

He stood dumbfounded, not knowing what he was thinking.

Chu Nan didn't dare to move, no matter how tempting the seven-grade energy source was, it was not as important as his life.

Time passed minute by minute, and seeing that the man in the green robe was stunned, Chu Nan was a little helpless.

"Ahem......" Chu Nan coughed lightly twice, and seeing that the eyebrows of the blue-robed man were raised, he spoke: "This senior, the connection between this blood crystal and this central large array is actually superficial, and it actually has a hidden formation. ”

The blue-robed man looked at Chu Nan, and the blood crystal instantly floated over.

This hidden formation is not an ancient formation, but a very ingenious small formation, this kind of formation trick is somewhat plausible with the Heavenly Array Sect.

Chu Nan divided five by two and unlocked this hidden formation.

The blood crystal was full of blood, and suddenly, a white crane phantom condensed, and this blood crystal began to become transparent.

The green-robed man's body trembled, staring blankly at the phantom of the white crane, and tears appeared in his eyes.

After a while, the white crane phantom was retracted and returned to the blood crystal.

And at this time, from the blood crystal, the image of a white crane could be seen.

The blue-robed man stared at it for a long time before putting away the blood crystal, and as soon as he raised his hand, a mass of brilliant seven-grade energy source was extracted, don't look at it as just a mass, the amount it contains can be described as extremely huge.

Chu Nan's heart twitched, it seemed that this blue-robed man was about to break his promise, and it was impossible for him to give up the seven-grade energy source to himself.

No matter what, in front of the powerhouses of the Taishen Realm, he has no qualifications to protest at all.

Just thinking like this, the blue-robed man suddenly stepped in front of Chu Nan, and actually directly punched the seven-grade energy source in his hand into Chu Nan's body.

Chu Nan's eyes were about to burst open, this was a complete seven-grade energy source, just stuffed into his body like this, he couldn't digest it at all.

At this moment, the blue-robed man pointed his finger at Chu Nan's body, and a terrifying force forcibly compressed the energy source that was about to explode, and directly transformed it into pure divine power, and then rushed to his Xuan veins like a river bursting its banks.

"Hey, what kind of colorful god base is this, it actually has seven colors. The blue-robed man felt Chu Nan's colorful divine foundation, and couldn't help but be very surprised.

The divine power entered the sixth Xuan Vein through the Seven-Colored Divine Base, and it became more and more pure.

The man in the green robe was even more surprised, he could even purify the divine power that he directly transformed, which was definitely more than the perfect divine foundation.

"The mutated Yuncai Divine Base is actually comparable to the Extreme Divine Base?" said the blue-robed man.

Immediately, the divine power of the sixth Xuan Vein of Chu Nan rioted, breaking through the sixth Xuan Tree, and then breaking through the seventh and eighth Xuan, which directly made him reach the ninth layer of the Void God Realm.

At this time, the blue-robed man stopped, and there was still a small half of the seven-grade energy source left, which was directly scattered on Chu Nan's body and limbs.

"I can help him break through to the Heavenly God Realm directly, but that is harmful to him, this kid's foundation is so solid, it is really rare in the world, the void god enters the heavenly god, if the god base is not complete, don't want to impact the Taishen realm in this life." The blue-robed man said in his heart.

Then, the blue-robed man left the underground hall like this, and the moment he left, Yue Peng recovered.

In the entire underground hall, only Chu Nan and Yue Peng remained.

Yue Peng stood behind Chu Nan in a daze, and suddenly, his dull gaze fluctuated violently, and there was a hint of agility.

He looked at Chu Nan, who was sitting cross-legged, and actually stretched out his hand and approached the back of his head.

Just as he was about to make contact, Yue Peng's gaze began to flicker violently, and suddenly, his gaze became dull again, and his hand retracted.

Soon after, Chu Nan opened his eyes.

"The ninth layer of the Void God Realm, how can it be reached so easily?" Chu Nan threw a punch, the space folded, and suddenly burst, and the energy contained in each of his cells was several times that of before.

"Look at my spatial claw again. As soon as Chu Nan raised his hand, the space distorted, turned into a sharp claw, and grabbed towards the void.

Chu Nan shrugged, the power of this innate secret technique comprehended in the Illusion Heavenly Aspect was weakened.

It's just because the vines of that spatial attribute are entangled in the tree of time, and the tree of time is now languishing, which also affects the vines of this space.

It seems that time and space are truly inseparable, at least in him.

Chu Nan turned his head, patted Yue Peng's shoulder, and said, "Senior Brother Yue, I've worked hard for you, let's go." ”

Out of the main hall, Chu Nan found that the dragon corpse was missing, presumably taken away by the man in the green robe.

"Who is this blue-robed man, who is sacred, could it be a certain Supreme Elder of the Taishen Realm of the Qingyun Sect?" Chu Nan thought.

Standing on the arch bridge, Chu Nan glanced at the deep passage, then at the underground river, and had an idea in his heart.

This passage must lead to some entrance and exit of the main peak, but you can take some risks to find out some news and see what is going on outside.

However, now I still go back the same way and talk to Kun Youqian and Wang Qianyun.

Chu Nan and Yue Peng jumped into the underground river and burrowed into the spring.

After a while, when Chu Nan was about to drill out of the spring on the other side, he suddenly felt an alarm, so he shrank into the spring, and a trace of divine thought quietly poked out.

"So, there is Qin Dong's breath in that cave, he must be somewhere in the belly of this mountain. ”

"Yes. ”

Chu Nan was shocked in his heart, that cave was discovered, and that Kun Youqian and Wang Qianyun might be more than lucky.

Chu Nan set up an isolation and concealment formation in this spring, and sneaked back to the end of the underground hall again.

"Senior Brother Yue, you just stay here, I'll go over there and have a look. Chu Nan said to Yue Peng.

"Qin Dong!" Yue Peng called Chu Nan's name and reached out to grab his sleeve.

"Okay, let's go together, but you have to be obedient. Chu Nan said to Yue Peng.

"Obedient. Yue Peng repeated.

Chu Nan looked at Yue Peng, how could he feel that his brain seemed to be a little brighter again.

Chu Nan and Yue Peng walked one after the other, walking towards the deep passage, and soon, the figure disappeared.

Qingyun Main Peak, a deserted remnant hall, the base of a statue suddenly slipped open, a head poked out, looked around, and then flashed up, it was Chu Nan, and soon, Yue Peng also followed.

It was calm outside, and it seemed that order had long since been restored.

At this moment, Chu Nan's heart jumped, and he and Yue Peng shrank in the shadow of a boulder.

After a while, two people approached while talking, and they were two female disciples.

"Why, I am also a disciple of the inner sect of the main peak, and I am so angry that I want to bow my head in front of that slut. ”

"Senior Sister Lin, the situation is stronger than people, and now that the third elder has become the deputy head of the sect, that cloud sleeve has fascinated Liu Dashao again, and it will be a loss to fight with her. ”

Cloud sleeves!

Chu Nan, who was hiding in the shadows, moved in his heart and continued to listen.

"I can't swallow this breath, and I can't afford to lose this person. ”

"Senior Sister Lin, but you also know the current situation, Liu Dashao was arrogant before, let alone now, if that cloud sleeve picks up a few words, I'm afraid that Liu Dashao will mess up. ”

That Senior Sister Lin was silent for a moment and said, "Could it be that you were humiliated by that slut like this?"

"Senior Sister Lin, when Israel always has an end of servants, Liu Dashao is now obsessed with cloud sleeves, and after a while, she is a reptile in front of you and me, and we can let her die how we want. ”

"What Senior Sister Xu said is true. ”

At this moment, the two female disciples suddenly felt dizzy, and the world seemed to change in an instant.

Immediately, they felt a pain in their heads, and they passed out.

I don't know how long later, the two women woke up, and when they opened their eyes, they saw a man with a disheveled hair staring at them.

Suddenly, they screamed, and then they found that they had no strength at all, except for their heads, the rest of the body was sore.

"Hello, two junior sisters. Just then, a voice rang out.

The two women looked over and saw a young man approaching with a smile, while the man with the disheveled hair stepped aside, staring fiercely.

"It's you, you're Qin Dong. Senior Sister Xu shouted.

"I have good eyesight, and I like girls with eyesight. Chu Nan smiled, reached out and pinched Senior Sister Xu's tender face.

"Qin ...... Senior Brother Qin, if you let us go, we will never say it. The woman surnamed Lin said in a trembling voice.

"Don't be so naïve, okay? Look at your Senior Sister Xu, she's much smarter. "Chu Nan Dao.

"Senior Brother Qin, what do you want? Senior Sister Xu said.

"Tsk, look, I, Qin Dong, am also a person who pities the fragrance and cherishes the jade, now, you tell me the situation outside. "Chu Nan Dao.

The two women poured beans and explained the situation again, now that the Qingyun Sect has been controlled by Kuzhu Zhenren, Kuzhu Zhenren has mobilized all the disciples to turn over the entire Qingyun Sect several times, and wants to pull Qin Dong out.

Moreover, the Lock Spirit Great Array has not been revoked, but only a small exit has been opened to allow people to enter and exit, and now ordinary people are unable to leave the Qingyun Sect by half a step.
