Yi Chen carefully observed around the big array, he didn't dare to get too close, the space around the big array was faintly distorted, and he only dared to look at it a few feet away, the more he looked at it at this time, the more surprised he became, every formation pattern on this big array was incomparably mysterious, only one of them, he observed half a full hour of incense, but he still hadn't seen through.

Yi Chen shook his head, walked around again, observed the other formations, and after nearly half an hour of incense, he finally pursed his lips and sighed lightly, this array is too mysterious, as the main formation of the peerless array, it contains too many secrets, and the formation attainment required to penetrate this array is probably extremely high, and it is not something he can do now.

"If it is Uncle Luo Zhen, he should be able to penetrate this array ......for a few points" Yi Chen muttered to himself, he didn't know Luo Zhen's array realm, he shouldn't have reached the ground formation division, but I'm afraid that at least he is also a very advanced person among the human array masters, if it is the latter, don't talk about understanding the entire big array, but he should be somewhat sure of a part of the comprehension.

"When will this Dao Pill become a ......?" Shaking his head, Yi Chen looked up at the huge copper furnace above his head again, frowned slightly, sighed, and said with a slight anxiety in his voice, he didn't have much time, he could only stay in this prison realm for seven days, and now more than a day has passed, if this pill has not been refined by then......

"Could it be that I want to return in vain this time?" Yi Chen frowned and said, the birth of Daohua Dan is right in front of him, this is a once-in-a-lifetime creation, if he can't get it, he is really unwilling.

Retracting his gaze, Yi Chen looked at the large array in front of him again, silent, but after a while, he shook his head helplessly and continued to comprehend around this array.

"The realm of the ground formation division can penetrate the terrain, and the formations of those stone platforms below should be used to condense the terrain, go up one after another, and penetrate this formation......" After observing for a long time, it really gave Yi Chen a rough glimpse of some doorways, and his eyes sometimes showed strangeness, sometimes puzzled, and he muttered speculation while watching.

And this array is set up at the highest point of the dojo, as if it is connected to the sky...... It should be condensing the heavenly potential!" Circling around the big array, Yi Chen muttered and whispered, and suddenly he paused suddenly, his eyes froze, as if he understood something, and his expression suddenly became shocked.

"This array intends to communicate the power of heaven and earth, Sect Master Zhang Fan is using the realm of the Earth Array Master to use the means of the Heavenly Array Master!"

Suddenly exclaimed, Yi Chen's expression was shocked, and his heart was completely unsettled, the Heavenly Array Division and the Earth Array Division were two completely different realms, one was heaven and the other was earth, almost incomparable, but Zhang Fan was speculating on the means of the Heavenly Array Master with the realm of the Earth Array Division, which was extremely terrifying, which shocked him!

Of course, the power of this array may be far inferior to the means of the Heavenly Array Master, but it is really intended to communicate the power of heaven and earth, and merge the two into one, which makes Yi Chen have to be amazed.

"My Tribulation Intent Array is also similar, attracting the Heavenly Thunder, this is also a kind of communication with the Heavenly Potential, if I can be like Sect Master Zhang Fan, condense the terrain with other formations, and then unite with my Tribulation Intent Array, I'm afraid the power of the Tribulation Intent Array can be multiplied a lot!"

But then, his brows furrowed, revealing a difficult color, condensing the terrain was the means of the Earth Formation Master, and it was far from being possible with his current Formation Dao realm.

Shaking his head helplessly, Yi Chen smiled bitterly, he also thought too highly of himself, in the end, he can only be regarded as a small human formation master who has just glimpsed the formation path now, and he is far away from the realm of the ground formation master, these are still too far away for him, and it is extremely difficult to get a glimpse of this formation.

He couldn't understand the structure of this array, but the method of arranging the formation could be used as a reference, so that he could gain some insights, although he could not apply this method to practice for the time being, but it might come in handy in the future.

Nodding with satisfaction, Yi Chen smiled, this harvest is already extremely valuable, when he has a higher level of formation attainment in the future, this method can help him double the power of the Tribulation Array!

Thinking of this, he immediately closed his eyes and sat cross-legged, his eyebrows lit up, and he followed the resonance and sensed it carefully, there must be some kind of connection between the main array that leads the heavenly potential and the nine formations that condense the terrain below, in order to achieve the unity of the power of heaven and earth, all he has to do is to find out this connection and figure out the method, this should not be too difficult!

Soon, Yi Chen's body also lit up with the formation patterns, his body fluctuations were gradually synchronized with this array, and the induction became more and more detailed, following the resonance as if he felt every corner of the large array, there was a trace of connection gradually flowing, surging to a direction, after a while, Yi Chen suddenly opened his eyes, looked at several formation patterns somewhere in the large array, and his eyes burst out with a strong essence light!

"This is it!" Yi Chen rose up, his eyes were like electricity, and he looked straight at the several mysterious formations in the center of the large array, and it was from these formations that there was a trace of hidden fluctuations, flowing downward, and connecting the nine arrays through the space!

"I don't have to worry about the other formations, but I must understand these few formations!" Yi Chen's expression was certain, and he secretly said in his heart, these several formations are the key to the formation of this entire peerless array, only by understanding it thoroughly, can he apply this method of combining the power of heaven and earth to practice in the future!

Immediately, his body moved, walked out around the large array, and stopped when he came to a place closer to the several formations, his eyes were blazing, and he observed carefully.

After a while, Yi Chen's heart felt something, and he immediately raised his fingers, and the aura surged, and he crossed the space in front of him, and copied the several array patterns out, and in an instant, there were amazing mysterious fluctuations, but they disappeared in a blink of an eye, seeing this, Yi Chen frowned slightly, this fluctuation was a little weird, and it was very different from the several array patterns in the large array, obviously he was not copying it correctly.

"It should be that something went wrong in the details...... Yi Chen muttered, he looked at the several formations again, observed them carefully, and after a while, he pointed and carved again, but it was still unsuccessful, the carved formations were clearly consistent with those in the big array, but the fluctuations that could be emitted were still completely different!

Shook his head, but Yi Chen was not discouraged, this is the big array left by Zhang Fan, naturally there are infinite mysteries, and it is normal that it is difficult to understand, even if it is only a few of them, it is not that he can successfully engrave them in a short time, he is ready to sit and comprehend.

Yi Chen continued to observe the formation patterns and kept trying to carve them, but after half a burnt incense hour, he had carved them a hundred times, but all of them were unsuccessful, but at this moment, his eyes were firm, and he was already a little sure in his heart, feeling that it was approaching, and the fluctuations of the formations he copied were gradually becoming similar to the several formations in the large array!

Soon, Yi Chen carved dozens of times, and the aura consumed a lot, but at the same time, the light in his eyes became brighter and brighter, and he felt that it was already very close, and it should be almost done!

He continued to carve, and the aura in his body passed rapidly, and the closer he got closer, the more intense the aura consumed by the formation pattern he carved, but Yi Chen was very excited, and even did not hesitate to take out the best spirit stone to supplement it crazily, if he could completely carve these several formation patterns, even if he consumed a top-grade spirit stone, it would be worth it!

After a while, Yi Chen's gaze retracted from the big array again, took a deep breath, and his eyes showed enlightenment, he copied and engraved hundreds of times, and realized that the several formation patterns were very profound, at this time, he was confident, and felt that he was ninety percent sure, and immediately his eyes were certain, and his fingers were carved again!

This time, Yi Chen's speed was extremely fast, and he was like a cloud and water in one go, but at the same time, the aura in his body was also disappearing at an extremely terrifying speed, and in just a breath, his body was completely empty!

But at this moment, Yi Chen's eyes showed excitement, and at the last moment, he carved out the several formations, right in front of his eyes, and emitted mysterious fluctuations, which were completely consistent with those on the big array!

He successfully carved it, and these several formation patterns were finally penetrated by him, and he grasped it in his hand, and when the formation path attainments were more profound in the future, he could use them practically!

"Huh" Yi Chen let out a sigh ......of relief, wiped his forehead, and was a little sweaty, this is not an easy task, it consumes spiritual energy and energy very much, but fortunately it succeeded, which made him very satisfied.

Yi Chen didn't continue to comprehend other formations, because this is Zhang Fan's array, the masterpiece of the realm of the Earth Formation Division, each formation pattern in the entire large array is closely related, intricate, and mysterious, he knows that it is difficult to understand, and even if he realizes a small part, it is useless, each formation pattern has its own reason for existence, and one is indispensable, once any one is missing, this array is no longer complete, and it cannot be a formation.

"Next, it's Daohua Dan......" His gaze was withdrawn from the big array, Yi Chen looked up at the huge copper furnace in the sky, and muttered in a low voice, his eyes gradually narrowed slightly, this Dan is the most important thing, it is related to whether he can build a foundation in harmony!

His eyes lingered on the phantom of the copper furnace for a long time, Yi Chen was a little anxious in his heart, a lot of time has passed, but this Dan still seems to have not been refined, Zhang Fan mentioned in the words left by Zhang Fan, Dan Cheng is three steps, and the third step is the purple light shining in the world, but at this moment he looked at the purple light in the sky, but frowned, although this purple light is huge and rich, but it is far from the point of covering the world, could it be that Dancheng has to wait for a long time?

"The Guzun Dojo is in the world, and this Dan must be refined, but as for why it has not been manifested into a Dan for a long time...... Maybe the reason is in that purple light. At this time, Yu'er's voice sounded in Yi Chen's ears, and it also carried some doubts, which made him immediately stagnate.

Immediately afterwards, Yi Chen's brows furrowed, and the uneasiness that had emerged before surfaced in his heart again, since he saw this purple light, he had always had a strange feeling, and it was even stronger at this moment, making him gradually have a bad premonition in his heart.

"There won't be anything wrong with this Dao Pill, right......"
