The relief statue on the wall of the secret library suddenly came alive, not only emitting blue light, but also had the illusion of moving coherently. It should be that the Yang Gui activated a certain formation, and the metallic spiritual patterns in the entire secret library began to be active. The blue light filled the entire hall, and the spiritual patterns on the wall outside the Blue Moon Gate shone together.

"Old Yang, what are you doing?" Gu Tianxiao asked sternly. This situation is not like a trial of entering the sect. Although he is not sure what it is, the fluctuation of spiritual power is definitely not a mild situation.

"This is the Ghost Yuan Formation that has achieved my ghost body. I voluntarily trapped here for the sake of the Tianqi Sect, but I also left many backs. This Ghost Yuan Formation, also known as the Thirty-Six Yin Ghost Spirit Detention Array, is now I will open this formation, and your trial is to enter the formation and eliminate these Thirty-Six Yin Ghosts."

Gu Tianxiao had never heard of this kind of ghost formation, but he could tell that the ghost body of the Yang Ghost is indeed related to this formation. Perhaps the energy of the Yang Ghost's domain is also related to this formation.

But this Yang Ghost is crazy, Gu Tianxiao has not wanted to accept any trial so far, so Gu Tianxiao decided to try it out again.

"Old Ghost Yang, what you stole from this formation is the spiritual energy of the core of the Apocalypse?"

"That's right, but Gu Tian laughed at you for using improper words. I am not stealing it, but just using it. I have said that without me, there would be no core of Apocalypse."

This is the second time Yang Gui said this. The first time Gu Tianxiao thought it was just crazy words, but now it seems that there should be some reason.

"Old Ghost Yang, what do you mean by saying this? Did you create this core of Apocalypse?"

The Yang Ghost maintained the casting posture, with faint light on its body, and the blue light around the wall gradually faded, from the previous flashing to a constant busyness of light. The reliefs turned out to be female ghosts one by one, with a total of thirty-six reliefs on all sides. After the blue light faded, they gradually showed their appearance. However, after so many years, these female ghosts had long lost their anger and turned into real dead objects. Under the power of the formation, they maintained mechanical dance postures. Fortunately, the faces of these female ghosts had faded away, otherwise they would not know how cunning they would be.

Yang Gui heard this and said, "The core of the Apocalypse is the secret treasure of the prosperity of the Apocalypse Sect. Of course, I cannot create it alone. After you become a disciple of the Apocalypse Sect, I will tell you."

"I want this young master to pass this trial?"

"That's right."

"Kill these thirty-six female ghosts?"

“That’s right.”

"How do you want me to enter this formation?" Gu Tianxiao asked again.

The Yang Ghost seemed to have completed casting. After a blue light flashed, only spiritual pattern sculptures were left on the wall. In the central open space in the secret library, thirty-six female ghosts seemed to have resurrected and began to twist and dance. These female ghosts were like Yang Ghosts, and their whole body was condensed into clothes and hair accessories. They were dark all over. There was only one female outline on their face. Although they were not as good as the six little ghosts and evil spirits in the late stage of the Killing Dan Realm that appeared at the beginning, these thirty-six female ghosts were also at the initial level of Killing Dan Realm.

Yang Gui pointed to the circle where the thirty-six female ghosts danced and said, "Gu Tianxiao, go to the center of those female ghost circles and kill these thirty-six female ghosts with your own strength. I will admit that you have completed the trial of entering the sect. At that time, I will tell you about the secrets about the core of the Apocalypse and some old things about the Apocalypse Sect."

Gu Tianxiao looked at the thirty-six female ghosts, and a hint of doubt arose in his heart. The six ghosts and evil spirits that appeared before had a higher cultivation level and had a hint of spirituality, which was more similar to the Yang ghosts. Although these dull and mechanical female ghosts began to dance in the power of the formation, they were real dead objects. Moreover, Gu Tianxiao noticed that although the contours of these female ghosts had faded, they were still extremely miserable faces. Six little ghosts and evil flew out from the walls on both sides of the left and right, and these female ghosts appeared from three walls, but there were no ghosts and evils on the wall behind the blue beads.

Gu Tianxiao always felt that there was a strange feeling in it, but he really couldn't think of what would be good for the Yang Ghost if he defeated these female ghosts now. Ruoyang Ghost just wanted to increase his strength, so there was no need to do this in one go. Could it be that as the Yang Ghost said, this is a trial for entering the sect?

At this moment, the sound of dawn came from Gu Tianxiao's heart.

"Report to the captain, Chenxi has completed the analysis of the blue crystal stone."

Gu Tianxiao was shocked, and then said to Yang Gui: "Old Yang Gui is related to the lifelong affairs of the sect. I want to consider it."

"Hahaha! Yes, but I only give you one stick of incense stick. Although these female ghosts can't see their appearance clearly now, they are all charming beauties during their lifetime. Gu Tianxiao, you can admire the dance posture while thinking carefully, but after a stick of incense, I will be strong."

Gu Tianxiao no longer responded to Yang Gui. In the void in his heart, Chenxi was already reporting the results of the blue crystal to him.

"Captain, this blue crystal is indeed a part of the core of the apocalypse."

"Is it a small piece of the apocalypse core? Can it serve as a power supply?"

"Captain, it cannot be said to be a small piece. What the captain may see is just a small piece of blue crystal, but it is actually a component that constitutes the entire apocalypse core. After investigation by dawn, this blue crystal is the control center of the entire apocalypse core, but there is no psychic reaction."

"Apocalypse core control center?"

Gu Tianxiao didn't understand. The core of Apocalypse is not just a source of energy supply?

"Chenxi, why does the Apocalypse core have a control center?"

Chenxi replied: "Captain, the Apocalypse Core itself is an extremely sophisticated spiritual tool. Captain, you think that a Apocalypse Core of this size can provide huge spiritual energy for the Apocalypse to operate, and it can also regenerate energy by itself. If it is just a regular consumption, the Apocalypse Core can be regarded as a permanent energy."

Gu Tianxiao always thought that the Apocalypse is very powerful, and the Apocalypse core is also very powerful, but I really didn't expect that the Apocalypse core was even more powerful than he thought. Originally, Gu Tianxiao thought that the Apocalypse core was just a high-concentration spiritual energy source similar to the spiritual vein essence source.

"So amazing! Chenxi, how many Apocalypse cores have the Tianqi Sect created?"

Chenxi responded a little slowly this time, "Captain, there is no such information in the Chenxi database. Chenxi only knows that the Apocalypse originally had ten Apocalypse cores, but when it is close to the same core, Chenxi can have sensing, just like the Apocalypse core here."

"Chenxi, is there any information created by the Apocalypse core, and how did the Apocalypse core created by the Apocalypse Sect?"

"Report to Captain, no."

This is just as Gu Tianxiao expected. Chenxi's database is simply "poor and white", but since this blue crystal is the control center of the Apocalypse core, the situation of this secret library is complicated again. Why is the center of the Apocalypse core separated and hidden in the illusion? Is it what the Yang ghost did or the ulterior motives of others?

"Chenxi, what can this blue crystal do now?"

"Captain, without this control center, the Apocalypse core cannot work normally. It can only be regarded as a general psychic energy source and will be consumed continuously. But the Qing Yuanzhu obtained last time is different. Although it only has one-third of the energy power, it can operate normally on the Apocalypse with the Control Center."

"There is a control center on the Qingyuan Bead?" Gu Tian asked with a smile.

"Yes, Captain, intact."

Wait... Gu Tianxiao seemed to have grasped the key point that had been ignored. In the Qingyuan Secret Realm, there were no ghosts and evil around this Qingyuan Pearl, and Nalan Qiong used a simple magic circle to break the seal at that time. Nalan Qiong was heading straight for this Qingyuan Pearl, and did not have much confrontation with the other Qingyuan Pearl that appeared later.

"Chenxi, without a control center, isn't this Apocalypse core unusable?"

"The captain, the Apocalypse core without the control center, is just a simple energy supply device that cannot be used in normal circumstances, but can forcefully extract psychic energy. On the contrary, the Qingyuan Bead with the control center can operate normally in normal circumstances, but cannot forcefully extract psychic energy through external forces."

"So Chenxi, can I understand this way, with the Apocalypse core with the control center, only those who know the correct method can use it normally. Otherwise, they can only break the control center first and use external forces to forcefully absorb spiritual energy?"

"That's right, Captain."

Gu Tianxiao finally understood that something was wrong with this Yang Ghost. Since this Yang Ghost set up a ghost formation to force the spiritual energy of the Apocalypse core, it can be seen that he should not know the true operation method of the Apocalypse core. Then what he mentioned himself is about is a problem.

Gu Tianxiao looked at the thirty-six female ghosts who were still dancing dullly, and Qingmian looked at him with a little meaning. When he communicated with Chenxi before, Gu Tianxiao did not hide the peeping of the seed of Qingmian.

"Qingmian, it seems that there must be a tough battle to fight, and you heard it too?" Gu Tianxiao sent a message to the seed.

"Well, you are a good method. You can still eat up the treasures under my nose."

"You can slowly understand this master's power in the future."

"Hmph! I have known for a long time that you are not honest. This old ghost is not a good thing. I have seen many such ghosts and evil spirits. Even if his predecessor was the leader of the Ri Sect, nine and a half out of ten will become completely different from those in his lifetime. But anyway, it is your trial. I am here to see if you can pass this so-called trial, which is also the test of me for you."

"Then you went to steal the beads secretly just now?"

"What do you know? I just want to test it."

At this moment, the sound of Yang Gui suddenly rang.

"Hahahaha! Gu Tian laughs, the time has come, tell me your decision quickly."

Gu Tianxiao looked at Yang Gui with a slightly majestic momentum, and his eyes became sharper.

"Haha, Old Ghost Yang, I am used to being idle, but I have no plans to join any sect."

"I love talents. Do you really want to let this great opportunity down? The secret of Tianqi Sect is extraordinary. Do you really want to know?"

"Stinky old ghost, do you really think that this young master is so easy to deceive? Look at these female ghosts yourself, they are all your masterpieces. Do you want this young master to become your ghost puppet?"

"Hahahaha!" Yang Gui burst into laughter again, and with a wave of his wicked arm, the female ghosts disappeared out of thin air.

"Gu Tianxiao, look around you. Since I don't listen to good words, I will be tough!"
