Call!

Chu Nan retreated decisively, retreated to the previous alchemy position, and at the fastest speed, put all the alchemy materials and alchemy furnace here into the spirit bag, and then his body moved, and he came directly to the exit position leaving the cave.

At the moment when he was about to step out of the cave, Chu Nan's right foot suddenly stepped towards the ground.

Under this step, the ground rose and fell like a wave in an instant, and in the roaring sound, it was like a python under the ground, which was moving quickly along the ground, and the target was ...... It's the formation that shrouds the box!

After taking this step, Chu Nan did not hesitate at all, let alone look at the result, and walked out of the cave directly, and quickly ran forward.

Haven't taken two steps yet......

Bang!!!

A huge roaring sound burst out from the cave, and its sound was like thunder, causing the entire towering giant stone pillar to tremble violently, and there were even cracks on the stone pillar that spread in the roar, and the impact of the air wave set off even rushed Chu Nan's whole person out, coughing up blood in his mouth!

Chu Nan's eyes were filled with shock.

Although he had already sensed that within that small formation, there were dangers that could threaten his life and death, but its power was still even more terrifying than Chu Nan imagined!

If Chu Nan hadn't been cautious enough and chose to leave the cave in time, he would have been buried in the cave now under the trigger of the formation!

"Ruthless!"

Chu Nan didn't expect that the sect master of the Nanxiao Sect would lay out such a killing machine.

Although Chu Nan was swept away by the wave of qi, but this injury was nothing to him, and now he returned to the cave, and found that the cave had completely changed, and it was broken everywhere, except for the stone wall and the box engraved with the formation, there was no longer a single intact place.

Chu Nan looked at the stone wall, this stone wall can allow the Nanxiao sect master to not ask the world here, at first glance, it is more than ten years, on the surface because of the esoteric formation engraved on the stone wall, but in Chu Nan's demon sense investigation, it was found that the Nanxiao sect master's gaze has always been only staring at one place, and has never moved, obviously not just because of the formation above, but there are other secrets.

Chu Nan wanted to take this stone wall away, but failed.

The stone wall couldn't be moved.

In desperation, Chu Nan could only give up.

Now that the box was in hand, Chu Nan immediately decided to leave this place and rush back to the Nanxiao faction first.

From the very beginning, he had already thought that his and Dong Yuchen's plan might not be able to be implemented perfectly.

He was well aware that plans could not keep up with the changes......

No matter how carefully he planned with Dong Yuchen in advance, he couldn't predict every step, and in the process of this plan, it was inevitable that accidents would happen.

It's like now......

Before he could refine those two kinds of pills, the rebellion had already broken out in advance, and Chu Nan had no choice but to adjust his earlier plan in response to this change.

He already had some ideas in his mind.

The specific situation is still to be arranged after returning to the Nanxiao faction.

And what he has to do now is to leave this place as quickly as possible and rush back to the Nanxiao Sect.

This is the end of my mind.

Chu Nan didn't stay here too much, his body moved, and he rushed out of the stone forest.

This stone forest formation will only target those who come in from the outside, and if they come out from the inside, there will be no trigger.

Therefore, Chu Nan easily walked out of the stone forest and rushed all the way towards the Nanxiao faction.

At present, when there is no one around, Chu Nan has nothing to keep and hide, and the speed is in full swing!

Rumble!

Chu Nan, who broke out at full speed, was astonishingly fast.

Soon......

Chu Nan had already seen the location of the mountain gate of the Nanxiao faction, and there was a fight breaking out at the mountain gate.

"Sure enough, the rebellion is ahead of schedule!"

Chu Nan's eyes flickered, and his body moved, passing over the spirit cultivators who were fighting between the two factions, and with his speed, he could completely pass by these spirit cultivators without being able to detect them with the naked eye, and directly enter the Nanxiao faction.

At present, the entire Nanxiao faction has been completely chaotic, and there are fights everywhere, not only the disciples of the Nanhong faction have invaded, but also the disciples of the Nanxiao faction have rebelled.

Chu Nan didn't intervene in the fight between the two factions, he was just an outsider.

Now he just wants to find Dong Yuchen as soon as possible and discuss the plan with him again.

Chu Nan guessed that Yi Dong Yuchen was now disguised as an elder, and at this time he might have entered the interior of the Nanxiao Sect, so he passed through these disciples on the periphery all the way to the square where Liang Dan was originally located.

The fight here is the most intense!

There were not only the disciples of the Spirit Fusion Realm fighting, but also the elders of the Yudan Realm.

Chu Nan hid in the corner, spreading out his magic sense, and the position of Dong Yuchen.

Soon.

Chu Nan found Dong Yuchen!

Dong Yuchen is not in the square now, after he came here, like Chu Nan, he did not fight, and he was also looking for Chu Nan.

Chu Nan used his magic sense to transmit the sound to Dong Yuchen at the moment.

"Don't move, you're waiting for me there. ”

Dong Yuchen, who was trying his best to find Chu Nan, the moment Chu Nan's voice appeared in his mind, the pupils of the whole person suddenly contracted, and a monstrous wave was set off in his heart.

"It's ...... Psionic sense??"

He was quite shocked.

He knew very well that even among those huge forces, the cultivators who could give birth to spiritual consciousness in the Yudan Realm were already extremely rare, and every one of them was a blazing sun.

Spiritual Fusion Realm Gives Birth to Spiritual Consciousness?

This completely turned his perception on its head!

Earlier, when they were in the castle in the tree, he had already discovered that Chu Nan could grasp the enemy's whereabouts in advance, and although he was surprised at that time, he didn't expect that Chu Nan had spiritual consciousness here.

He felt that it was more likely that Chu Nan had some kind of detective treasure......

However, now Chu Nan's transmission directly confirmed that he had given birth to spiritual consciousness, which made Dong Yuchen in shock, realizing that Chu Nan was far more unfathomable than he imagined!

Call!

It didn't take long for Chu Nan to rush over and join Dong Yuchen.

"I've had an accident here and we need to change our plans. Chu Nan said in a deep voice.

Dong Yuchen nodded.

Although he was shocked that Chu Nan had given birth to a demon consciousness in the Spirit Fusion Realm, he also knew that now was not the time to think deeply, so Lian said quickly.

"Before we change our plans, I need to tell you one thing first, this matter is related to the grievances between the Nanxiao Sect Sect Master and the Nanhong Sect Master, as well as the ...... behind them Secret!"

Chu Nan's heart moved.

In fact, he also felt that there was a secret in this Nanxiao Sect, and this secret was inextricably linked to the fact that the sect master of the Nanxiao Sect had been watching that stone wall all these years!

Earlier, Chu Nan and Dong Yuchen had already known that in the former Nanxiao Sect, there were three Great Perfection powerhouses in the Dan Realm.

However, these three Great Perfection powerhouses of the Jiedan Realm started a battle twenty years ago in order to compete for the hidden treasure in the Nanxiao Sect.

One of them fell in the battle, and the sect leader of the Nanxiao faction and the sect leader of the Nanhong faction suffered different degrees of trauma.

The war at that time......

The Sect Master of the Nanxiao Sect was the one with the least injuries, so he took control of the Nanxiao Sect, became the Sect Master, and obtained the hidden treasure of the Nanxiao Sect.

The sect leader of the Nanhong faction could only be forced to leave the Nanxiao faction and establish a new sect.

Now what Dong Yuchen wants to tell Chu Nan......

It's about the three of them in the Great Perfection of the Dan Realm, the reason why they fought twenty years ago, and the secret behind that hidden treasure!

"As early as more than twenty years ago, the sect leader of the Nanxiao Sect was a strong man named Sun Lu, this person was extremely strong, not only had the cultivation of the Great Perfection of the Jie Dan Realm, but also had a lot more combat power than the ordinary Great Perfection of the Yu Dan Realm!"

"Whether it is the current Nanxiao Sect Sect Master, or the Nanhong Sect Sect Master, as well as the Great Perfection powerhouse of the Yudan Realm who died in battle, it was just him back then...... Disciple of the seat!"

"However, this sect master of the Nanxiao Sect mysteriously disappeared one day!"

After that, no matter how they searched, they couldn't find a trace of this Nanxiao sect master, as if the world had evaporated. ”

"The disappearance of this sect master of the Nanxiao Sect has a meaning that I don't know, which makes the three Great Perfections of the Dan Realm panic. ”

The three of them began to fight for the hidden treasure. ”

"About that hidden treasure...... I don't have much information, but I have heard what the Nanhong Sect Sect Master means, and it seems that the reason why they want to fight for that secret treasure is also for ...... Find the old sect master who has mysteriously disappeared!It seems that there are some clues about the old sect master in that hidden treasure......"

"Over the years, the Nanhong Sect Sect Master has been very unwilling, and he has always wanted to recapture those hidden treasures and grasp the whereabouts of the missing old Sect Master. ”

In other words, the reason why he started the rebellion and did all these things was for the sake of ...... Look for the missing old sect master!"

"It's a pity I couldn't find out why...... But I know that not only the Nanhong Sect Sect Master, but also the current Sect Master of the Nanxiao Sect have been trying their best to find the missing old Sect Master over the years. ”

"Their fighting, their snatching, their everything...... It's all for the sake of finding the missing old sect master!"

Dong Yuchen's words instantly made many thoughts emerge in Chu Nan's mind.

Now he can be sure......

The reason why the sect master of the Nanxiao sect has been facing that stone wall for ten years and not asking about the world seems to be because of the formation on the stone wall, but in fact, there is a clue of the mysterious old sect master on the stone wall, and he has been contemplating it, trying to find this clue from it......

At the same time, Chu Nan also ruled out the possibility that the stone wall was the hidden treasure of the Nanxiao Sect.

Although he had never seen the secret treasure of the Nanxiao Sect, through many clues, he was ninety-nine percent sure that this hidden treasure was ...... It must be something ancient!

And after absorbing the demon bones, he has a sense of these ancient things, and when he touches them, his body will transmit suction power, thus absorbing them.

At that time, when he touched the stone wall, he did not react at all, so it can be concluded that ...... That stone wall is definitely not the hidden treasure of the Nanxiao Sect, it should be that the Nanxiao Sect Sect Master has been the sect master for decades, and he accidentally discovered that stone wall, so he has not left the cave for more than ten years.

"Why do they have to look for that old sect master?"

This is the biggest mystery in front of Chu Nan and Dong Yuchen today.

And the reason for this is known only to the sect masters of the Nanxiao Sect and the sect masters of the Nanhong Sect......

"Maybe if you get your hands on that secret treasure, you'll know why!"

Chu Nan's eyes flashed slightly.

In any case, the Hidden Treasure is the most important thing to him.

"What do we do now?"

Dong Yuchen looked at Chu Nan.

"For my protector of the Dharma, I want to be here...... Alchemy!"

Chu Nan already had an idea in his heart.

"Alchemy?here?"

Dong Yuchen was stunned for a while.

"Yes. ”

Chu Nan nodded, didn't say much, and directly took out the alchemy furnace from the spirit bag.

He believed in Yidong Yuchen's ability, and it was not difficult for him to be undisturbed in the process of his alchemy.

And he was ready to refine a ...... that would make all the cultivators of the Yu Dan Realm feel excited Poison Pill!

This poison pill, Chu Nan is ready to dedicate to the final victor.

If in this rebellion, it is the Nanxiao faction sect leader who wins, then Chu Nan will go and dedicate this pill to the Nanxiao faction sect master. If the sect master of the Nanhong faction wins, then Chu Nan will hand over this pill to Dong Yuchen and let Dong Yuchen take it and dedicate it to the sect master of the Nanhong faction!

If both sides lose, then Chu Nan will let Dong Yuchen detonate the blue flower he left on the Nanhong sect master, so as to create a chance for the Nanxiao sect leader to kill, and then Chu Nan will go and dedicate this poison pill to the Nanxiao sect master.

What Chu Nan wants to do now......

It's to make a ...... When any cultivator in the Yudan Realm sees it, he will be thrilled, he will be crazy about it, and he will be desperate to snatch and swallow it...... Poison Pill!

The refining of this poison pill needs to be combined with the two kinds of pills that the sect master of the Nanxiao Sect asked Chu Nan to refine earlier.

Chu Nan thought about it for a long time, and finally came up with a way to refine these two kinds of pills.

He was going to use the power of the Heavenly Wolf Land to refine it.

Call!

Immediately, with a wave of his palm, he lifted the lid of the alchemy furnace in front of him, put a lot of herbs into it, put his hands on the furnace, closed his eyes, and began alchemy.

During the refining process, he used the power of the Heavenly Wolf Earth to integrate it into the alchemy furnace to ensure that he could complete the refining of this poisonous pill.

Originally, with his alchemy attainments, this level of Dan was not something he could refine, but the power of his Heavenly Wolf Birth Land could make up for his shortcomings and let him forcibly refine it, after all, this was the power of the entire Heavenly Wolf Birth Land...... If you want to condense a poison pill, you can still do it.

......

At the same time as Chu Nan was doing alchemy here.

Behind Nanxiao Sect Square, in front of a huge humanoid statue, two figures stood at the left and right ends of the statue, looking at each other from a distance.

"Wei Ya ......" The sect master of the Nanhong faction dressed in white, his body was thin and small, but his eyes flashed with a fierce light, looking at the sect master of the Nanxiao sect dressed in black, and said coldly.

"I have given you that secret treasure for twenty years, and it is time for you to return it to me today. ”

"Let?"

The sect leader of the Nanxiao Sect, Wei Ya, sneered with contempt.

"From the moment you Hong Ming entered, you were under me, and to this day, you are still under me, so are you qualified to say this word?"

As soon as Wei Ya's words came out, the anger of Hong Ming, the sect leader of the Nanhong faction, suddenly rose.

"If you hadn't been used in that battle at the beginning, causing me to be more seriously injured than you, today's Nanxiao Sect Sect Master, will it be your turn?"

"It's not helpful to say more. ”

Wei Ya's expression was indifferent. "You are planning to start this rebellion just to fight me and snatch the secret treasure, and now you don't need to talk this nonsense, do it. ”

Hong Ming's eyes narrowed slightly, suppressing the anger in his heart, and trying to ease his tone.

"Actually...... We don't have to fight, we have the same goal, we are all to find out the master, in the past twenty years, you have occupied the Nanxiao faction, mastered the secret treasure, and you must have learned a lot about the clues of the master, and I am here...... Over the years, we have also gained some gains, if we integrate each other's information and search together, we will definitely be able to find the master. ”

Wei Ya didn't speak, and grabbed his right hand towards the void.

Wow!

Suddenly, a black cold war spear appeared in his hand, and the entire war spear was cold and gloomy, exuding extremely powerful terrifying fluctuations, distorting the surrounding air.

Hong Ming's eyes were cold.

The other party's actions directly showed his attitude, and he wanted to ...... War!

However, Hong Ming didn't feel strange about Wei Ya's move, he knew that with the other party's mind, he was not so easy to be fooled, and he didn't even bother to talk to him.

"Then let's fight!"

Hong Ming's eyes surged with murderous intent.

In a flash, a black war spear that was incomparably similar to Wei Ya's appeared in his hand.

Rumble!

A huge roaring sound, accompanied by the fight between the two, completely broke out in the Nanxiao faction, and for a while, the color of the heavens and the earth changed, and everyone in the Nanxiao faction could clearly feel that these two terrifying forces were constantly colliding, and every time they collided, the ground would tremble wildly.

Dong Yuchen, who was protecting the Dharma for Southern Chu, also felt this earth-shattering collision.

"Is there a war......

He couldn't help but look at Chu Nan.

Chu Nan was still immersed in alchemy.

He can only continue to protect the Dharma for Chu Nan and wait.

......

At this time, Chu Nan was at an important moment.

His eyes were red, his eyes were bloodshot, there was a layer of fine sweat on his forehead, his expression was solemn, and his whole mind was completely immersed in it.

Although he had the power of the entire Heavenly Wolf Birth Land, refining this poison pill still held a huge challenge for him.

"It must be successful!"

Chu Nan's heart prayed.

Soon, there was a roaring sound in the Dan furnace, and it was already at the last moment.

Chu Nan held his breath and looked nervous.

Rumble!

There was a loud bang.

The Dan furnace stopped.

When Chu Nan unveiled the Dan Furnace, a cyan light burst out from the Dan Furnace, and inside the Dan Furnace, a poisonous pill with a cyan luster that was only the size of a fingernail appeared......

"It's done!"

Chu Nanqiang couldn't help but feel excited.

Reaching out to hold the poison pill, his consciousness directly entered the Divine Tree Dojo to take the most important step...... Quality Improvement!

Now, although he has successfully refined this poison pill, before the quality is improved, this poison pill has not yet reached the level that can attract all the powerhouses of the Formation Pill Realm.

After entering the Divine Tree Dojo, he immediately passed through the Divine Tree to improve the quality of this poison pill.

Call!

After being promoted by the Divine Tree, the cyan color on this pill was constantly converging inward, and in an instant, the color of the pill became much lighter.

"Is this layer of cyan poison?"

Chu Nan's eyes flashed.

In his eyes, this elixir was mediocre, no matter how he looked at it, even if he swept it with his demonic sense, he couldn't see a trace of speciality.

Chu Nan knew......

This is because his cultivation is not enough!

Even if this pill was refined by him, but his cultivation did not reach the realm of knotting pills, he would not be able to see the extraordinaryness of this poison pill.

And if they cultivate to reach the Sect Pill Realm, or if they see this poison pill in an existence above the Pills realm, there will be some differences in this poison pill in their eyes.

After successfully improving the quality of the poison pill, Chu Nan's consciousness left the Divine Tree Dojo and returned to his physical body.

Call!

Chu Nan opened his eyes.

"Is it done?"

Dong Yuchen looked at it with a curious face, his eyes were focused on the elixir in Chu Nan's hand, no matter how he looked at it, he couldn't see anything extraordinary about this elixir in Chu Nan's hand.

Chu Nan was full of confidence.

"Now we just have to wait for the results. ”

The roaring sound outside, as well as the tremor of the earth, all made Chu Nan realize that now these two Great Perfections of the Dan Realm were engaged in a fierce battle.

Now they only need to wait for the two Great Perfections of the Dan Realm to divide the winners and losers, and then they can start to act.

"You poison pill...... Can it really be done?"

Dong Yuchen hesitated.

Although he had never seen those powerful elixirs, he had also heard of those powerful elixirs, which would shock people's hearts just by looking at them, but now the elixir that Chu Nan had refined was too ordinary, too ordinary.

"If the two of us Spirit Fusion Realm can also see the extraordinariness of this elixir, then it is not worth being the key this time. ”

Chu Nan said.

Dong Yuchen nodded.

With the current contact with Chu Nan, he continued to feel some shocking and unbelievable things from Chu Nan, and he didn't have too many doubts about this elixir.

"When you were refining the pill, I thought of something......

Dong Yuchen said. "Since there are clues about the old sect master in that hidden treasure, is it ...... in the box containing the hidden treasure? There will be clues too?"

Dong Yuchen's words made Chu Nan's mind flash.

That box......

There is indeed a possibility that there are clues!

Otherwise, the sect master of the Nanxiao Sect would not have arranged an amazingly powerful formation under the box earlier.

At that time, Chu Nan had doubts, if the sect master of the Nanxiao Sect was just to prevent himself from taking the box, there was no need to arrange such a powerful formation at all, Chu Nan was just a cultivator in the middle of the Spirit Fusion Realm in his eyes, he only needed to casually lay out a formation to kill.

However, the power of the formation arranged by the sect master of the Nanxiao Sect under the box is extremely terrifying, not to mention the ordinary Spirit Fusion Realm, even if it is triggered by a strong person in the Yu Dan Realm, there will be a crisis.

"That formation...... He didn't prepare it to prevent me from getting the box, but to ...... Prevent a strong person in the Yu Dan Realm from getting the box!"

Chu Nan's eyes flickered.

This is all the more indicative of what makes the box special.

"Are those two boxes still on you?"

Chu Nan looked at Dong Yuchen.

Dong Yuchen nodded.

The sect leader of the Nanhong faction has always put these two boxes here in Dong Yuchen, and asked Dong Yuchen to take him for safekeeping, and Dong Yuchen also took out these two boxes and studied them earlier, but he didn't see anything, and he didn't find anything.

He suspected that he had to take out all five boxes and put them together to form a complete box, perhaps to see the clues.

And now......

The other three boxes are on Chu Nan!

Chu Nan immediately took out these three boxes, and put them together with Dong Yuchen's two boxes to form a complete black box!

This black box was not big, but it exuded the aura of an ancient era that Chu Nan felt familiar.

Chu Nan stared at the black box carefully, trying to find clues from it, but found nothing.

"You can't see any difference with the naked eye, you can look at it with your spiritual sense. ”

Dong Yuchen was also observing, and he couldn't find the difference from the box.

Chu Nan immediately investigated with his magic sense.

"Huh?"

He was surprised to find that in the box, there were many secret patterns, these secret patterns were located inside the box, so they could not be seen by the naked eye, but most of these secret patterns were dim, only one of the secret patterns, emitting an extremely faint light.

The moment Chu Nan's magic sense penetrated into the secret pattern.

Rumble!

His mind shook.

There was a secret that poured into his mind from this secret pattern.

"This place is a ...... Prison!"

"A hundred years ago, in order to imprison a sinner who had committed a heinous crime, this place was sealed, so that this place, centered on the Nanxiao Sect, was sealed within a radius of millions of miles, thus forming this prison......! Can't get out of this prison!"

And the name of this imprisoned sinner ...... Sun Lu!"
