"Nine-colored dark iron?" After hearing these four words, Nie Lingfeng's heart suddenly shook, but his face became more and more calm, and even his tone did not change at all, and said, "Senior, what is the nine-colored Xuantie?" ”

"The nine-colored dark iron is the core of the true spirit world, and only by gathering nine pieces of nine-colored dark iron can we refine a true spirit world!" Speaking of this, Xuanyuan Immortal Emperor's tone was already very proud, and he only listened to him continue: "Now in the entire Immortal Domain, only I can gather these nine pieces of nine-colored Xuan Iron, and the old man of the Chaos Immortal Emperor is even delusional about refining his own True Spirit World, hum!" Even if he used the spirit grass of the Immortal Medicine Planet to attract immortal realm cultivators, he didn't find all this nine-colored Xuantie! ”

"Could it be that this nine-colored dark iron is very difficult to find?" Nie Lingfeng continued to ask.

"It's not very difficult to find, but this thing can only be found by monks under the cultivation of scattered immortals, because once the cultivation of monks reaches the Daluo Golden Immortal, then, these nine-colored dark iron will have the effect of rejection, even if you cultivate to the sky, don't try to catch it!"

"Then the Chaos Immortal Emperor can't collect all of this nine-colored dark iron at such a big price?" Nie Lingfeng continued to ask.

"How can it be so easy!" Xuanyuan Immortal Emperor sneered: "Hmph, this guy is notorious, those who know don't dare to trade with him, and those who don't know can't find the immortal medicine planet, besides, if you want to get together this nine-colored Xuantie, you can't do it just by chance, you need to look back and forth in the upper, middle, and lower three days, and if you're not careful, you will be swallowed up by the spatial turbulence, hum!" ……”

"It seems that the guy who found the nine-colored dark iron is really blessed!" Nie Lingfeng couldn't help but sigh in his heart, but. Now it's all cheaper!

"Do you have any questions?" Speaking of this, Emperor Xuanyuan Immortal turned his head and asked.

"I want to ask, how should this nine-colored dark iron be cultivated, and after my sacrifice is successful, can I take this true spirit world for myself?"

"I will help you during the sacrifice, and as long as you succeed in the sacrifice, this true spirit world will become yours, that is, you are the master of this true spirit world!" Xuanyuan Immortal Emperor said with a smile.

"Ordinary sacrifices are made with divine sense, but why don't you sacrifice this true spirit world yourself?" Nie Lingfeng said suspiciously: "With the divine sense cultivation of the predecessors. It should be easy to refine this true spirit world that belongs to you in the first place, right? ”

"Huh!" Hearing Nie Lingfeng's words. Xuanyuan Immortal Emperor smiled, and then said helplessly: "Even if I succeed in the sacrifice now, I can't leave this True Spirit World, after all, my divine sense can't be exposed!" ”

"Alright, let's get started!" After Nie Lingfeng got the answer he wanted. Then he nodded.

"Don't worry!" Xuanyuan Immortal Emperor smiled. Said: "We need to enter the formation!" ”

Under the leadership of Emperor Xuanyuan Immortal. Nie Lingfeng easily entered the outer protective array of this nine-colored Xuantie, and the function of this protective array was to make it impossible for the nine-colored Xuantie to leave the center of this true spirit world.

After entering the formation, a familiar and terrifying aura greeted him. Frightened, Nie Lingfeng almost sacrificed the Linglong Pagoda, but after seeing Xuanyuan Immortal Emperor motionless, he finally held back.

And here, Nie Lingfeng finally saw the true face of the nine-colored Xuantie.

The aura of the nine-colored dark iron Nie Lingfeng was already very familiar with it, if he hadn't really felt that it was the nine-colored dark iron floating and rolling in the formation in front of him, he might have suspected that the nine-colored dark iron in his hand was a fake!

"This is the core of the True Spirit World?" Nie Lingfeng looked at the nine-colored Xuantie that was rolling wildly and muttered.

"yes!" Xuanyuan Immortal Emperor nodded and said: "The function of this nine-colored dark iron is to activate the true spirit world, only within this spirit enlightenment formation, the aura of this nine-colored dark iron will be stripped out and can drive this true spirit world." ”

"Enlightenment Formation?" Nie Lingfeng looked at the complex formation in front of him in confusion, as well as the nine-colored dark iron within the formation, which was like a seven-colored pillar of light rolling wildly on the stage, and couldn't help but wonder: "Do you still want to enter this Enlightenment Formation?" ”

"That's not necessary!" Xuanyuan Immortal Emperor shook his head and said, "As long as you probe your Divine Sense into the Enlightenment Formation, and then attach the Nine Divine Senses to the nine pieces of Xuantie, then this True Spirit World will become your own world!" ”

"It's that simple?" Nie Lingfeng said curiously.

"Yes! It's easy! ”

"But, why don't I know much about this formation?"

"Yes, it took me more than six thousand years to arrange this formation, so if you want to fully master this formation, I'm afraid it will take at least ten years!"

"More than ten years?" Hearing Xuanyuan Immortal Emperor's words, Nie Lingfeng was suddenly shocked.

"Yes! If your divine consciousness can't enter this formation at will, then don't think about dividing it into nine parts and attaching those nine pieces of dark iron separately! ”

"...... this?"

"Moreover, your nine divine senses must be exactly the same, and the attachment on each piece of dark iron must be the same, otherwise, it will have no effect at all!" Xuanyuan Immortal Emperor continued.

"What?" Nie Lingfeng was dumbfounded, if he let himself separate the nine divine senses to attach the nine pieces of dark iron, although there was a difficulty, it was not impossible to complete, but if he wanted to make every wisp of divine consciousness exactly the same, it would be simply impossible! Don't say that he is just a monk at the peak of the Yuan Infant Stage, even if he reaches the peak of the Tribulation Period, such a thing is difficult to complete, after all, the division of the divine consciousness is very difficult, and the monk needs to have at least a very strong and meticulous divine consciousness, just like giving you a piece of pork and asking you to divide them into nine pieces of pork of exactly the same size, and there is also no need for any difference, if you don't use tools, then there is simply no possibility!

"Don't worry!" Xuanyuan Immortal Emperor knew what Nie Lingfeng was thinking in his heart, so he smiled and said, "I will teach you a divine sense cutting technique, if you cultivate to the third layer, then you can cut your divine consciousness into any equal parts at will, and even, after reaching the fourth layer, when you attack others, you can completely use uninterrupted divine sense attacks, and." It won't deplete your divine sense, and this is a great opportunity for you! ”

"Really?" Hearing that there was such an anti-heaven exercise, Nie Lingfeng suddenly became more interested, and said, "Senior, how should I operate it now?" ”

"While cultivating this Divine Sense Cutting, while studying the formation, after three months, look at the effect, I think as long as your formation is introduced, you will also learn the first layer of this Divine Sense Cutting!"

"Yes!" Nie Lingfeng took the two jade cylinders handed over to him by Emperor Xuanyuan Immortal and immediately sat cross-legged on the ground. Start researching. Even, he didn't even know when the Xuanyuan Immortal Emperor left.

I don't know how much time has passed, Nie Lingfeng has only raised his head from the study of the formation, and at this time, the Xuanyuan Immortal Emperor has not yet come. But now Nie Lingfeng's cultivation of divine consciousness cutting has reached the first level. Even. He believed that when his formation went further, this Divine Sense Cutting could be promoted to the second subordinate! And the formation he studied now has an eyebrow. After all, he was already a formation grandmaster!

The complexity of this Enlightenment Formation is no less than that of a giant overlapping array, if it is placed on the Green Planet where the formation cultivation is relatively high, I am afraid that no one will be able to comprehend it in such a quick time, it is because they do not have this Divine Sense Cutting Technique.

And what Nie Lingfeng didn't expect was that this Divine Sense Cutting Technique was inextricably linked with the Enlightenment Spiritual Array, it seemed that when this formation was arranged, Xuanyuan Immortal Emperor used a lot of Divine Sense Cutting Skills, and even, at that time, Xuanyuan Immortal Emperor's Divine Sense Technique should be the sharpest technique in the world!

And Nie Lingfeng has only successfully cultivated the first layer of exercises now, he feels that his divine sense has not only solidified a lot, but even slightly enhanced, in the past, if he wanted to use his divine sense to probe the mind of his slave, he needed to calm down and meditate, but now, he only needs to extract the wisp of his slave's divine consciousness to feel the other party's thoughts, and this aspect alone is more than a little bit stronger!

Since it was now a bottleneck, Nie Lingfeng didn't want to continue researching, after all, the best way to break through the bottleneck was not to study all the time, but to relax his mind.

Now, Nie Lingfeng began to straighten out the purpose of the Xuanyuan Immortal Emperor.

This Xuanyuan Immortal Emperor is definitely not a good person, just imagine, an Immortal Emperor who has cultivated for tens of thousands of years, or even hundreds of thousands of years, even if he is kind and grateful for his "life-saving grace", he will not give his true spirit world to himself, this is a top-grade immortal weapon! Even, in the entire Immortal Cultivation Realm, this True Spirit World is still the only existence! Just imagine, even among the Da Luo Jin Immortals, how many people will have high-grade immortal weapons in their hands? Moreover, if Xuanyuan Immortal Emperor didn't say the true use of this True Spirit World, it showed even more that he was using himself!

Indeed, no Immortal Emperor would spend time and energy cultivating such a seemingly chicken-like true spirit world for no reason. In Nie Lingfeng's opinion, this True Spirit World definitely has a special effect on the Immortal Emperor! Not to mention that this true spirit world needs a treasure that defends the sky like nine-colored dark iron, even a single grass, tree, mountain and stone in this true spirit world cannot be easily obtained. If it was really like Xuanyuan Immortal Emperor explained, he could easily sacrifice a small world, and even, the small world he sacrificed could definitely allow human beings to survive!

However, knowing that Xuanyuan Immortal Emperor was using himself, he had no choice, after all, the high-grade monk in the Tribulation Period had no power to resist in the hands of Xuanyuan Immortal Emperor's wisp of divine sense, which means that if Xuanyuan Immortal Emperor wanted to deal with himself, I am afraid that he only needed to move his little finger!

Nie Lingfeng is not a monk who is willing to be controlled by others, but at this time, his skills are not as good as others, so he can only forbear! Moreover, Nie Lingfeng can also be regarded as an earthling, so Han Xin can endure the humiliation of his crotch, when he faces the Xuanyuan Immortal Emperor, whose cultivation is much stronger than himself, what he can do is to save his own life first, and then step up his cultivation, and when the Xuanyuan Immortal Emperor can't control himself, that's when he fights back!

I think that when he was just a junior monk in the Jindan period, he could calculate the treasure spirit Venerable who had the Yuan Infant, and now that he had reached the peak of the Yuan Infant Stage, he could still "play" with a wisp of divine consciousness of an immortal emperor?

Since Nie Lingfeng's formation cultivation was already very good, after practicing the Divine Sense Cutting Technique alone for a few days, the shackles that had originally blocked his formation research were suddenly broken somehow, and a refreshing feeling that filled his soul suddenly made his Divine Sense Cutting Cultivation skyrocket, and at the same time as the formation cultivation was improved, his Divine Sense Cutting Technique also stepped into the second layer of the realm.

Immediately, he was once again immersed in the "work" of cultivating and breaking the formation.

Time passes slowly. During this period, Nie Lingfeng encountered three bottlenecks, but each time he was able to solve the problem on his own, but now this time, he encountered very big difficulties, and he hadn't studied the Enlightenment Formation for more than ten days!

At this time, Nie Lingfeng's Divine Sense Cutting Technique had also steadily advanced to the peak of the third layer. He knows. Once one's Divine Consciousness Cutting Technique can advance to the fourth layer, then all the changes in the Enlightenment Array will be able to be fully mastered by oneself, because. This Divine Consciousness Cutting Technique and the Great Spiritual Enlightenment Array are complementary to each other.

By this time. Only then did Nie Lingfeng understand. If a monk hadn't practiced Xuanyuan Immortal Emperor's Divine Sense Cutting Technique, then this Enlightenment Great Array would not be able to be arranged at all. On the other hand, even if you know how to arrange the Enlightenment Formation, if you don't have this Divine Consciousness Cutting Technique, then everything will be in vain.

Of course, there are thousands of Divine Consciousness Exercises in the Immortal Cultivation Realm, and there may be monks who also have very sharp Divine Sense Exercises, and they can also use Divine Consciousness Exercises to arrange the Great Spiritual Formation of Enlightenment, but Nie Lingfeng believes that if the other party has not cultivated this Great Divine Sense Cutting Method, then even if he has studied it for ten thousand years, he will not be able to arrange or master the essence of this Great Spiritual Formation of Spiritual Enlightenment.

Nie Lingfeng now knew the sharpness of the Enlightenment Array, and even more understood the invincibility of the Divine Sense Cutting Technique. Before cultivating the Divine Sense Cutting Technique, Nie Lingfeng already felt that his Divine Sense was very powerful, and he even dared to use his Divine Sense to compete with the low-grade monks of the Tribulation Period, but now, he felt that even if he encountered a high-grade monk of the Tribulation Period, he would dare to use his Divine Sense to fight against him! It's not self-confidence, it's a sign of real strength.

I saw that Nie Lingfeng closed his eyes, and his divine consciousness had quietly flown out, and more than 15,000 meters away, Nie Lingfeng clearly saw Qin Zihan and Hua Ruyan who were cultivating cross-legged in the True Spirit Palace, of course, that Dong Lao Wei, the Sword Zhenren, etc., could not escape the observation of their own divine sense, and before he practiced this divine consciousness cutting technique, his divine consciousness could not even see this fifteen-thousand-meter center of the earth!

Maybe he felt that Nie Lingfeng's divine sense had left the ground, and suddenly, Xuanyuan Immortal Emperor's body appeared in the back garden of the True Spirit Palace, but Nie Lingfeng looked like he was very tired, and he also felt a little unrelenting.

"You are indeed a genius of the Heavenly Vertical," after entering the underground, Xuanyuan Immortal Emperor first praised Nie Lingfeng, and then said with a wry smile: "I really didn't expect that it only took you two years to practice the Divine Sense Cutting Technique to the peak of the third layer, alas! I think I had a master to teach me back then, but it took me nearly ten years! ”

"Senior, but now I have encountered a bottleneck, many days have passed, and I still have no clue!" When Nie Lingfeng heard Xuanyuan Immortal Emperor's words, although he was a little complacent, he raised his question very calmly.

"Hehe," Xuanyuan Immortal Emperor couldn't help but smile when he heard Nie Lingfeng's words, and then said, "Don't say it's your current cultivation, even if your cultivation has reached the Soaring Stage, don't even think about advancing to the fourth level of the Divine Sense Cutting Technique at this time!" ”

"Why is that?" Nie Lingfeng stammered.

"I'll be honest with you!" Xuanyuan Immortal Emperor glanced at Nie Lingfeng, and then said: "Actually, this Divine Consciousness Cutting Technique and the Enlightenment Formation of mine are a whole set of cultivation exercises, that is to say, if your formation cultivation is improved, the Divine Consciousness Cutting Technique will also be improved, and if your Divine Consciousness Technique is improved, the formation cultivation will naturally also be improved, I have been studying this formation since I advanced to the Tribulation Period, of course, the further this Enlightenment Formation goes, the more difficult it will be to improve my cultivation, and when my Divine Sense Cultivation fully reaches the ninth layer, My formation cultivation has also reached its peak, and even, at that time, my cultivation has reached the Scattered Immortals! ”

"Oh?" Nie Lingfeng was surprised: "Could it be that as long as I study the formation in front of this Enlightenment Formation in the future, my cultivation will automatically improve?" ”

"Auto-raise, that's impossible!" Xuanyuan Immortal Emperor shook his head and continued: "Because you have now reached the peak of the Yuan Infant Stage, you must survive the Heavenly Tribulation to reach the Tribulation Period, and in this True Spirit World, you cannot cross the Tribulation, unless you have become the master of this world, and moreover, the cultivation of the Tribulation Cultivator cannot exceed the Yuan Infant Stage, because this True Spirit World cannot withstand the Heavenly Tribulation of the Tribulation Period Monk at all!" Once the Heavenly Thunder is induced, maybe the entire True Spirit World will collapse! ”

"Oh!" Nie Lingfeng finally understood, and couldn't help but smile bitterly: "So if I can't successfully cultivate this True Spirit World, maybe I will never be able to improve my cultivation?" ”

"Yes!" Xuanyuan Immortal Emperor nodded and said: "If you can't become the master of this True Spirit World, then, don't think about leaving this True Spirit World, since you can't leave the True Spirit World, then of course you can't cross the tribulation!" ”

"So what do I do now?" Nie Lingfeng couldn't help frowning.

"I originally thought that I could control the Fire Phoenix with this wisp of my divine sense, but in the past two years of observation, I found that the cultivation of the Fire Phoenix had actually reached the realm of the human cultivator Scattered Immortals! I didn't even dare to release my divine sense, if I provoked the fire phoenix, maybe I would be gone! Xuanyuan Immortal Emperor did not answer Nie Lingfeng's question, but instead spoke to himself.

"Fire Phoenix?" Nie Lingfeng was stunned when he heard this, and couldn't help but wonder: "What are you going to do to control the Fire Phoenix?" (To be continued......)
