In the space inside the apse, there is indeed a large magic circle. At first glance, Yue Yu was attracted by the few spirit stones on the shelves in front of the hall. Looking at the quality luster, as well as the amplitude of energy fluctuations, I am afraid that the bottom is above the fifth grade.

Yue Yu was surprised and delighted in his heart. He knew that this level of spirit stone, even if it was placed in the entire Northern Wilderness, was extremely rare. It is also a must-have for refining the magic weapon of Xuanbing. However, when his gaze swept over the wooden frame and cast it onto the formation map behind, his face suddenly froze.

The core and source of spiritual power of this Great Array of Protectors is actually the Five Elements Gathering Spirit Array. It's just that the magic circle is not only much more complex and mysterious than his version, but its effect is far beyond that. Coupled with its location, it is located in the spiritual center of this cave, and the difference in effect between the two is really not to be calculated,—— but it is a pity that the five fifth-series spirit stones that are the source of the spiritual power of the magic circle are now extremely dull and have even more traces of fragmentation. Faintly, there are signs of collapse.

Yue Yu took a closer look at the distance spirit array, and then looked at the wooden frame beside him. This should be the spare replacement spirit stone for the Beppu Great Array, but in the past few hundred years, for some reason, no one from this Jinghai Sect has ever come here.

At this time, the entire large array suddenly shook violently again. The five spirit stones in that array were already close to the edge of shattering. Yue Yu hesitated slightly, then gritted his teeth violently and replaced those spirit stones on the wooden frame one by one. However, there are only four spirit stones on this wooden frame, and there is still a lack of one of the most critical water spirit stones.

Yue Yu checked his Sumeru space again, and then took out a spar that also shimmered with a blue-black luster.

In fact, among the more than 100 spirit stones he obtained, there was also no completely pure water spirit stone. Two days ago, he had been searching for a long time before he found a six-grade spirit stone that was mainly water and mixed with a very small amount of fire and gold spiritual power. Then he directly guided with his inner breath, extracted all the two spiritual powers of those Huo Hejin, and then smashed all the structures in the spirit stone that could absorb and store these two types of spiritual power.

And this time, fortunately, he had already prepared-"Most of this Jinghai Sect is also based on water system skills and secret methods! If it weren't for that, this water system would not be so scarce as a pure surname spirit stone!"

While thinking wildly, he analyzed the spirit stone in his hand in detail to see if there was anything missing. The whole process took Yue Yu about three minutes, and just as he was almost finished, the water spirit stones within the Five Elements Spirit Gathering Array had completely shattered. Yue Yu couldn't care so much for a while, and directly pressed the black and blue spar in his hand. And what made him feel extremely fortunate was that the entire Five Elements Spirit Gathering Array only delayed a little before it started running again.

The only pity is that these six-grade spirit stones are still a little worse. It only ran for a moment, and its luster was already slowly fading at a slightly invisible rate. The speed at which it absorbs the spiritual power of water is far from keeping up with its consumption.

- If it is replaced by the fifth grade, then this Protector Array can support it for another seven hundred years! But the piece in front of him will exhaust his spiritual power in three months at most. The difference in quality between the two can be seen from this. And at this moment, when someone breaks through the formation, it is even more difficult to say how long it can be supported.

In addition, this gap in quality also made the speed at which the entire Five Elements Spirit Gathering Array extracted the spirit of heaven and earth by a whole two grades!

However, in Yue Yu's eyes, there was not much frustration. His original idea was to use the spirit stones of different castes that he had obtained from Beppu to temporarily maintain the operation of this large array after he entered here. It's just that in this way, it is destined that the power of the magic circle will decline significantly. Being able to find these four fifth-order stones in this apse is already an unexpected joy.

With the infusion of a large amount of spiritual power, the spiritual array at the dome, as well as the entire Beppu, was suddenly full of spiritual power again. Yue Yu knew in his heart that the people above would never be able to attack in a short period of time. It was only at this time that he let go of the anxiety in his heart and began to carefully examine the space of the entire apse.

Yue Yu just glanced at those dense rune arrays, and after using the intelligent system to write them down, he didn't care about them anymore. Anyway, he had only seen less than one-fortieth of these esoteric talismans, and even if he spent a few more months studying them, he might not be able to understand them.

The next thing that caught his eye was a silvery-white circular metal frame at the back of the hall, shaped like a mirror, but hollow in between.

However, what caught Yue Yu's attention the most was the rune that gathered with it as the core under the silver frame. It formed a spirit array alone, but it was closely connected to the entire Protectorate Array. And there is a small part of it, which can be said to be extremely similar to the puppet's soul control array. In addition, directly above the silver-white frame, there is indeed a palm-sized purple jade piece embedded in it.

"Could it be that this is the center of this great array?"

This thought flashed in his mind, Yue Yu strode over, and then touched the soul jade with his hand. On this, like the outer doors of the main hall and the apse, there is a water-based spiritual power-based seal, which is estimated to require a special legal decision to open. However, Yue Yu didn't bother to care about so much, a five-colored divine light spilled out from his fingers, and the power of his soul consciousness had already invaded it without hindrance.

And just like the piece he had seen before, there was a purple book of jade slips that recorded more than ten evil dao exercises. When Yue Yu's soul power had just penetrated into it, there was this thought, pouring into his mind. It's just that in terms of strength and quantity, it's far from the former.

Yue Yu carefully checked the information it carried, and then unsurprisingly, he found that this soul jade not only had the function of the purple book jade slip, but also the control center of the entire mountain protection array. And what that information carries is some of the rules and essentials of regulating the Great Array.

And when the last few pieces of information were browsed by him, Yue Yu's eyes were full of surprise, and he looked at the silver-white frame in front of him.

"It turns out that this thing is actually a magic weapon used to activate the Thousand Miles Shadow Technique-"

Outside the dense forest, with a series of spiritual power changes, Chu Yun's face was already as condensed as water. And at this moment, it was not only him, but all the monks nearby who were under the foundation of a slightly stronger gnosis could not hide the panic and astonishment in their eyes at this moment.

"Uncle Shi, I'm afraid there's something wrong with this!"

Zuo Rong frowned and looked around. His soul power is not very good, and he can detect the abnormality of the situation from the changes in the situation around here. Originally, the entire hilly area was visually deflected at the moment. Although there are less than three times in this case, and all of them have changed back to their original state after an instant, and it is extremely inconspicuous. However, an innate grandmaster like him has always been sensitive to changes in the external environment. These anomalies may not be noticed by ordinary people, but they will never be able to hide from him.

Chu Yun didn't answer, his eyes were still looking at the front steadily. He had noticed something different before. The spiritual power in the phantom array was already abundant again. And the spiritual power stirring inside all calmed down, turning into a death-like silence.

frowned and pondered for a long time, and the worry and doubt in Chu Yun's eyes became more and more intense.

"Of course something is wrong, someone in this Beppu has already entered it one step ahead of us, and most of them have already controlled the center of this Protectorate Circle. I miscalculated this time—"

"How is that possible? How did they get in?" Zuo Rong and several people all changed color in unison. In the past few days here, from the heavens and the earth, all the forces of the Xueyin Gate and the Cloud Gate have been watching them to death day and night. Even if the others were Jindan-level monks, they were afraid that it would be difficult for them to break in silently.

"What's impossible? Wasn't that person just trying to control the whole array?"

The corners of Chu Yun's lips were slightly raised, but the doubts in his heart were also strong, how did the person who was trying to control this big array get into the seemingly unbreakable Jinghai Sect Beppu?

Compared with this worry, the worry in his heart at the moment is even stronger. The phantom array set up by the Jinghai Sect is exquisite and abnormal, and between the indulging of people and the autonomous operation of no one, the power can never be said to be the same. Mu Xiyao broke into this formation, and the risk can be said to be doubled!

Thinking about the underground people, since they have the ability to enter the cave without a sound, their strength must be extraordinary. Chu Yun only felt his heart, and suddenly grabbed the person.

- Endless fear welled up in his chest. He doesn't want any treasure, no elixir, he just wants his junior sister to come back completely!

At the same time, it was about seven miles within the phantom array. Mu Xiyao also frowned slightly, and glanced around. The scene in front of me is no different from what I just had. She could also see the fluctuations in the aura and spiritual power of the monks of the same rank not far away. But she instinctively felt that something was wrong with the situation.

This came from a few minutes ago, when she felt that the spiritual power of the water in her vicinity, which was already declining, suddenly regained its strength. She originally thought that this was also an illusion created for her by the prohibition of this spirit array, and she also played an illusion breaking talisman at that time. And after that, sure enough, the spiritual power around it regained its weakness.

But at this moment's peace of mind, Mu Xiyao's heart only lasted for ten minutes. At first, she didn't feel abnormal, but gradually, she felt that something was wrong, and her chest gradually felt like her mood was beating.

"Avoid water!"

"Illusion!"

"Calm down!"

Three talismans were shot out in a row, and along with the water spirits around him, they were once again discharged. After regaining clarity in her brain, Mu Xiyao looked at her carefully, but there was still nothing wrong with her. The only change before and after the rune is activated is the visual difference. But in this phantom array, it is still normal.
