As soon as the words of the two fell, Qiao Yuan suddenly paused, his expression showed surprise, Qu Yunwei saw that Qiao Yuan's expression was wrong, and hurriedly asked.

"Qiao Yuan, what's wrong?"

"I just sensed a formation fluctuation here, wait a minute. ”

Qiao Yuan's eyes froze, and he hurriedly said a word, and then he sat directly cross-legged on the ground, and his divine sense swept extremely carefully within a few feet nearby.

After a cup of tea, Qiao Yuan frowned and opened his eyes, he didn't notice anything abnormal, but the feeling that flashed just now was extremely real, definitely the fluctuations from the formation.

Suddenly, a flash of inspiration flashed in Qiao Yuan's mind, and he remembered that in the ninth secret room on the second floor of the Forbidden Tower, he had encountered a similar scene, but there was an invisible forbidden, and there might be an invisible formation here, and it was very likely that this invisible formation was the center of the labyrinth trapped formation.

The more Qiao Yuan thought about it, the more he felt that this was very possible, and without hesitation, he stood up directly, moving his steps behind him very slowly, and at the same time, his eyes were closed, carefully feeling the formation fluctuations that might appear at any time.

Qu Yunwei was quite puzzled when she saw this scene on the side, but when she saw that Qiao Yuan was looking for something very seriously, she naturally didn't bother, but guarded it very carefully.

After a while, Qiao Yuan opened his eyes suddenly, a gleam flashed in his eyes, and at the same time, he groaned slightly, and then sat down cross-legged again.

He did feel an extremely faint formation fluctuation here, which was quite similar to the scene in the ninth secret room of the Forbidden Array Tower, but the difference was that the formation fluctuation here was not detected by the mysterious power generated in Qiao Yuan's body, but by himself.

In the past month or so, Qiao Yuan has spent a lot of time studying the forbidden formation, and his attainments in the formation have improved by leaps and bounds, and the discovery of this invisible formation also relies on his keen insight.

Discovering this formation does not mean that Qiao Yuan has the ability to crack it, after all, I don't know which ancestor of the Moon River Sect arranged this formation, and if it stays here, it must be useful, and it is impossible for people to crack it easily.

Qiao Yuan found and studied this formation, just to determine whether there would be a formation in the future, so as not to trap the two of them in the maze again, in addition, if through this formation, find the map of this place, or some other clues, then this chance is great.

Qiao Yuan calmed down and put all his thoughts on this subtle formation fluctuation, wanting to follow the vine and touch the claws to find the formation center.

Time passed slowly, Qiao Yuan's divine thoughts slowly disappeared with the trajectory of this formation, for some reason, as long as his divine consciousness followed the trajectory of this formation, he would not be suppressed by that strange force, and could extend a hundred zhang away.

Suddenly, Qiao Yuan's divine consciousness found that there were several more formation fluctuations, and they converged with this one, this formation was like an extremely complex net, criss-crossed, converged and dispersed, Qiao Yuan's divine consciousness was extremely subtle, as if it was integrated with the formation fluctuations, and did not cause the rejection of the formation.

Half an hour later, Qiao Yuan opened his eyes suddenly, and his eyes burst with a dazzling essence, with a look of joy and excitement.

"I've found the center of the formation. ”

Qiao Yuan stood up and hurriedly said a word to Qu Yunwei with a smile, and then he turned around and returned the way he came.

Seeing Qiao Yuan's expression, Qu Yunwei hesitated for a moment and followed, but she would leave a spiritual power mark every fifty zhang, so it was good to leave a way back.

Qiao Yuan's speed was extremely fast, and he passed through the three crossroads in a blink of an eye, and then he stopped in front of an extremely ordinary oil lamp, without hesitation, Qiao Yuan quickly pinched the trick with both hands, punched out a few seals, and lit it on the oil lamp.

The wick swayed from side to side, and the dim light seemed to be about to go out, and after a few moments, the spark in the oil lamp rushed up, then contracted sharply, and in an instant, it was extinguished without warning.

Qiao Yuan didn't show a look of surprise, without thinking, he went directly into the distance, this time he passed through the five crossroads, and also stopped in front of an extremely ordinary oil lamp, pinched out the seal with both hands, and hit it, as before, the oil lamp was full of fire but extinguished in an instant.

Qu Yunwei kept following Qiao Yuan's back, her beautiful eyes showed a strange glow, and she didn't speak, but looked at the extinguished oil lamps.

These oil lamps seemed to her to be extremely ordinary, but every time Qiao Yuan pinched out the seal and put it on it, a hidden spiritual power erupted from the oil lamp, and then this spiritual power seemed to be withdrawn, and the oil lamp was extinguished because of this.

Qiao Yuan then stopped in front of the six oil lamps, punched out the seal, and let them go out, and then he returned to the nineteenth passage again, standing in the center of the crossroads, Qiao Yuan didn't know what method he used, and pressed his palm on the ground.

There was a rumbling sound, the labyrinth seemed to be collapsing, the ground began to tremble slightly, and suddenly, where Qiao Yuan pressed it with a palm, a seven-inch long and wide stone platform slowly rose and stopped when it rose to Qiao Yuan's waist.

Then the stone platform opened layer by layer, and a hexagonal array disk slowly rotated in it, Qiao Yuan's eyes showed a strange light, his eyes stared at this array plate tightly, and at the same time, he patted the storage bag, took out a similar hexagonal array disk, formed a sword with two fingers, and pointed out continuously on it.

The hexagonal array in this stone platform is the center of the formation here, and it is varied, extremely complex, and contains many formation principles, if Qiao Yuan can study this formation thoroughly, then his formation attainment will reach a shocking level, even Duan Tiangu will be moved by it.

However, Qiao Yuan can only think about this matter, and he can't do it in a short period of time, unless he is here to study this array plate for tens or hundreds of years, there is a slight possibility, and what he has to do now is to imprint the changes on this array plate in the array plate he took out, so as to study it slowly in the future.

At this moment, Qiao Yuan's expression was extremely excited, as if he had discovered a great treasure, in his opinion, even if this trip did not obtain the inheritance, just a little fur of this array of plates could be called a great opportunity.

In a blink of an eye, it was three hours, and in these three hours, Qiao Yuan was almost motionless except for his hands constantly clicking on the array, his expression was so focused that Qu Yunwei was a little surprised to see it, she believed that even if this maze collapsed now, Qiao Yuan would not notice it.

Time passed slowly, and unconsciously, Qiao Yuan had been here for twelve hours, his eyes were bloodshot, and there was no expression on his face, if Duan Tiangu was here, he would definitely be able to see at a glance that Qiao Yuan seemed to have entered the realm of complete contemplation, and even had a tendency to transition to the realm of micro-heart.

Qu Yunwei called him twice halfway because she was worried about Qiao Yuan, but Qiao Yuan was still branding the array as if he hadn't heard it.

Thirteen hours, fifteen hours, and finally at the eighteenth hour, Qiao Yuan's eyes were closed, his body was soft and fell directly to the back, Qu Yunwei on the side saw this, his face changed, and he hurriedly stepped forward to support Qiao Yuan.

"Qiao Yuan, what's wrong with you?"

Qu Yunwei looked worried and shouted urgently, but Qiao Yuan seemed to be unconscious and did not respond at all.

"The spiritual power is depleted, how can this be?"

As soon as Qu Yunwei's consciousness came out, she directly probed into Qiao Yuan's body to see what happened to him, and after a while, Qu Yunwei showed a puzzled look on her face and whispered to herself.

Then Qu Yunwei flattened Qiao Yuan's body, took out more than ten medium-grade spirit stones, and put them beside Qiao Yuan, Qu Yunwei sat cross-legged beside him, and used a special method to attract the spiritual power in the spirit stone to pour into Qiao Yuan's body to make up for the loss of spiritual power in his body.

An hour later, Qiao Yuan slowly opened his eyes and saw Qu Yunwei sitting cross-legged on the side, he immediately understood everything, looking at Qu Yunwei's beautiful face, Qiao Yuan showed a grateful smile on his face, and said softly.

"Thank you. ”

"No thanks, by the way, you were just studying this array, how could you suddenly faint and the spiritual power in your body was exhausted?"

Qu Yunwei smiled slightly and said softly, but then she looked puzzled and asked.

In her opinion, studying the array disk would consume some mental energy at most, and it would not consume much spiritual power at all, and it was the first time she had seen the monk fall into a coma because of the exhaustion of spiritual power.

"Well, I've just entered a strange state, and this state has a great drain on my mind and spiritual power, so that's why it's like this. ”

Qiao Yuan's eyes showed exhaustion, and he said slowly.

This is the first time he has been in the Sinking Heart Realm for more than ten hours in a row, so the loss of his mind and spiritual power has reached a limit, so that he is in a coma and forcibly exits the Sinking Heart Realm.

Qu Yunwei saw the tiredness in Qiao Yuan's eyes, and knew that this was not the time to ask, so she told him to meditate and breathe first, and then talk about it later.

Qiao Yuan nodded, raised his hand and waved, and there were also more than a dozen medium-grade spirit stones near him, and with these spirit stones, he began to spit out quickly.

Three hours later, Qiao Yuan's state returned to its peak again, he glanced at the array disk in his hand, put it away, and then looked at the array plate on the stone platform, formed a sword with two fingers, and counted the points on it, and the stone platform slowly sank into the ground and disappeared.

This array was the center of the formation here, and he couldn't take it with him, but he had already imprinted many changes in this array plate into his own array.

And he also has some understanding of the formation of this inheritance trial land, although he can know that it is all some fur, but it is these furs, Qiao Yuan is equivalent to getting a head start that others do not have.

"Qiao Yuan, you seem to have gained a lot?"

Qu Yunwei didn't understand the formation array, but when she saw Qiao Yuan's face full of spring breeze, she was curious, so she asked casually.

"Well, this array has been of great help to me in my research on the forbidden formation, and I also know some things about this inheritance trial land. ”

Qiao Yuan was in a very good mood, turned his head to look at Qu Yunwei, and said with a chuckle.

As soon as she said this, Qu Yunwei's curiosity became even heavier, and she hurriedly asked.

"What's the matter?"
