Then, after the black flame churned, it turned into a wisp again, and disappeared into Yuan Fei's fingertips.

In fact, Yuan Fei had already left his back hand, and if Jiahe really cooperated, he would naturally spare his life. But if he is still stubborn, he can only repay his body in the way of others.

Yuan Fei glanced back and saw that there were no storage bags left on the ground, but there was a piece of purple ore and a black crystal bead the size of a thumb.

Yuan Fei's expression moved, and as soon as he grabbed it in the air, the two objects appeared in his hand in a flash.

"I think this is what he calls an 'ethereal stone'. As for this crystal bead, hiss...... Could it be the 'Heaven-Shaking Bead'!" Yuan Fei said thoughtfully, and suddenly remembered something, and couldn't help but exclaim.

The effect of this ethereal stone, Yuan Fei just heard Jiahe talk about it, is used to fuse its primordial spirit to make up for the shortcomings of the primordial spirit.

As for the black crystal beads, Yuan Fei was really moved after thinking about it for a while.

Speaking of which, the origin of this black crystal bead is extraordinary, it is said that it is called the 'Heaven Shaking Bead', which is condensed by the thunder of the Immortal Tribulation obtained by the great mana of the Immortal Tribulation Monk when he crossed the Immortal Tribulation. It's so powerful that it can almost threaten the existence of the Tribulation.

Of course, although the rumors are a bit exaggerated, with the prestige of the Immortal Tribulation Thunder, it is unimaginable for the monks, at least the cultivators in the God Refining Stage should not be able to resist the power of the Heaven Shaking Bead.

At this thought, Yuan Fei couldn't help but feel afraid for a while. If Jiahe really urged this bead, even if it had a lot of means, I am afraid that there would be no bones left.

However, since this pearl has fallen into his hands, it is naturally very different. Yuan Fei, who was still a little worried about this trip, added a lot of confidence.

After Yuan Fei secretly scolded Jiahe a few words, he carefully put away the Heaven-Shaking Bead, and then pinched the trick with one hand, and his body immediately turned into invisible, and disappeared strangely.

Half a day later, Yuan Fei had quietly returned to the secret room and looked at the jade slip that Jiahe handed over to him.

At that time, Yuan Fei just briefly checked it, but with his current knowledge, he naturally saw at a glance that the content in the jade slip did not seem to be fake. Therefore, after returning to the secret room, Yuan Fei studied it carefully.

"I didn't expect that refining the Void Heaven Stone still needed to use the Spatial Divine Power to do it, no wonder I was never able to refine it. At this time, Yuan Fei's divine sense was withdrawn from the jade slip, and a sudden look appeared on his face.

Yuan Fei touched his chin, pondered for a moment, then put away the jade slip, and then flipped his palm and took out another jade slip.

Naturally, it is a jade slip that records the method of controlling the demon destroying array.

In fact, Yuan Fei knew in his heart that although it was a method of control, what they had in their hands was at most some assistance, and as for the most critical method of control, it must still be in the hands of Feng Xiu, Qingyao and other great cultivators.

However, even if it is an auxiliary method, it is quite troublesome to comprehend, not to mention Yuan Fei, who is not deeply involved in the formation.

Therefore, in case something went wrong at that time, Yuan Fei concentrated on comprehending the control method of the Demon Slaying Array.

Time flies, and seven days pass in a blink of an eye.

In the Ghost Light Palace, the Grand Commander Feng Revised the Great Horse Golden Dao sat on a black broad chair, and Wan Hailei, Liao Changkong and Zhong Lingyu, the three late-stage existences, had already sat down on the seats.

As for Yuan Fei, he sat on one side with Heyan and the other four mid-stage monks, all of them silent, looking like they were looking at Wan Hailei and the others.

"I wonder if you have comprehended the method of controlling the Great Array?" Feng Xiu suddenly asked after sweeping his gaze on everyone's faces.

"This is natural, I don't know when I will leave to rush to the Sealing Demon Tower?" Wan Hailei nodded.

"Wan Daoyou is really a man of temperament, and he always takes this matter to heart. Feng Xiu said with satisfaction.

"Daoyou is polite, this matter is related to the two races of the human and underworld, the reason why the old man and others came here is not only to help the nobles, but also to prevent the ancient demons from fleeing to the human world to do evil. Wan Hailei said with a solemn expression.

"Alright, in that case, I'll leave at once. After Feng Xiu said the word "good", he suddenly shook one hand, and a black light shot out from it, and rose in the wind in the flash of light, turning into a black flying boat several feet in size.

Feng Xiu said the word "please", shook his shoulder, and appeared in the flying boat strangely.

Wan Hailei, Liao Changkong, and Zhong Lingyu, the three late-stage existences, saw this, and they fell into it without saying a word.

And Yuan Fei and others also took off into the air and boarded the flying boat.

After Feng Xiu casually punched a few runes into the flying boat, the boat immediately buzzed, and a layer of light appeared, protecting a group of people in it, and broke through the air loudly, and flew straight to the void in the distance.

The speed of the flying boat was extremely fast and did not stop at all, and after flying for a full hour, the speed slowed down slightly.

It turned out that the surrounding brilliance was flashing, and a lot of magic circles were actually set up, and I could vaguely see a huge black tower dozens of feet high standing not far ahead, and there were many monks sitting around.

Thinking about this black giant tower, it is the Demon Sealing Tower that Feng Xiu said in his mouth.

Before they got closer, Yuan Fei and the others saw the flickering of the runes on the surface of the Sealing Demon Tower, and there were bursts of muffled thunder from it, accompanied by a wild howl, which made people feel a trace of fear in their hearts.

Seeing this, everyone couldn't help but glance at each other, and they could see the horror in each other's eyes.

It didn't take much effort, the flying boat came to the vicinity of the Sealing Demon Tower, and everyone flew out of it, and as soon as Feng Xiu raised his hand, the black flying boat immediately shrank rapidly, and disappeared into its sleeve.

"I think this is Wan Daoyou, Liao Daoyou, and Fairy Zhong, right?" As soon as everyone appeared, two rays of light rose into the air below, and as soon as the light flickered, an old man in a green robe and an old man with a white beard appeared, and it was the old man in the green robe who spoke.

"These are the two Dao brothers Qingyao and Yunque. Feng Xiu raised his hand and introduced to Wan Hailei and the others.

"The two Taoist friends have passed, I don't know what the situation is now?" Wan Hailei hugged the two of them.

"To tell you the truth, we have been guarding the Demon Sealing Tower for all these years, and although the ancient demons are stubborn, they are still within our control. But lately, the ancient demons have become more ferocious, and it seems to be even more terrifying than before. Qing Yao said solemnly.

"If Liao is not mistaken, this Sealed Demon Tower should be a spiritual treasure, right? Could it be that such a treasure can't trap it?" At this time, Liao Changkong looked at the Sealed Demon Tower carefully for a while, and couldn't help frowning.

"To tell the truth, this magic tower was originally a treasure left by the ancestors of the underworld, and even if we joined forces, it was only half refined. However, before, it wasn't too much of a problem to trap the ancient demons whose cultivation was greatly restricted. But from what I've observed over the years, it seems that there is only one ancient demon in this magic tower now. Yun Que explained with a sad face.

"Wouldn't it?, could it be that one of the ancient demons had already died?" Zhong Lingyu wondered.

"What the fairy said is true, but we are guessing that it is not so simple to fall, it is very likely that it was devoured by another ancient demon. A hint of worry flashed in Yun Que's eyes.

"Devouring the Soul Devouring Yuan!" At this time, Yuan Fei, who had never spoken, suddenly thought of something and exclaimed.

Hearing this, everyone couldn't help but move, and turned their heads to look at Yuan Fei one after another.

"I don't know what this fellow Daoist is called?" Qing Yao glanced at Yuan Fei and said.

"This is the old man's junior brother 'Yuan Fei'. Wan Hailei introduced.

"I don't know what Yuan Daoyou meant just now?" Qingyao nodded.

"I take the liberty of going underneath. Speaking of which, I have a slight understanding of the things in the upper realm. If you are not mistaken, if it is really as Yun Que Daoyou said, the reason why this demon devoured another ancient demon is not only to nourish itself, but the most important thing is to absorb and refine the true demon qi of the other party's body.

You don't know that the true demonic qi is different from the ordinary demonic qi of the nether, relying on the true demonic qi to make its own power soar several times no matter what kind of exercises or secret techniques are urged, which is why even though the two demons were suppressed in the later stage of cultivation, and the underworld power was far stronger than the other party, it still took a huge price to seal it. Yuan Fei's face sank and said.

"Is this true?" Hearing this, everyone present looked shocked, and Qing Yao exclaimed in surprise.

"To be honest, this is also a conservative estimate, and there is no exaggeration. Yuan Fei smiled bitterly in his heart.

The scene of the Beihan Continent group's cultivation battle against the mysterious monk of the Biling Immortal Palace, even now, is still fresh in his memory, as long as he thinks about it, he is still a little afraid.

"Fortunately, I found out in time, otherwise it would have been hard to imagine what the result would have been. By the way, since Yuan Daoyou knows something about this matter, I don't know what can be done to help me destroy this demon?" At this time, Feng Xiu was secretly shocked for a while, and couldn't help but feel a move in his heart.

And the others no longer dared to despise Yuan Fei, their expressions were fixed, and their eyes all fell on Yuan Fei.

"According to the following inference, the battle between the ancient demons and the underworld should have consumed a lot of true demon qi, otherwise it would be difficult to be forcibly suppressed. Therefore, even if it devoured another ancient demon, it would not get too much True Demon Qi. Therefore, as long as we can join forces to stalemate with the ancient demons for a while, and when they exhaust the true demon's qi, there will be nothing to fear. Yuan Fei pondered for a moment and then said.

"It's hard to say, Feng doesn't believe that I and so many other beings will make a move together, plus with the assistance of the Feng Magic Array, I can't fight against it. After Feng Xiu's heart was relieved, he couldn't help but feel a little more sure.

"That's true, but I'd better be careful, just in case. Wan Hailei saw Yuan Fei's solemn face, and knew that this matter was not so simple, so he still reminded him.

"What Wan Daoyou said is very true, my Underworld Monk has already prepared, just waiting for you to arrive. Since what Yuan Daoyou said is so serious, we will urge the Demon Extermination Array as soon as possible, and we must not let this demon get out of trouble in advance. Qing Yao said with a solemn face.
