The hundreds of metal sheets that Yue Yu created were only more than one meter long. However, when they were on flat ground, when they were combined by the three of them through the card slots at the edge, they were a huge circle with a circumference of three hundred and fifty meters and a diameter of more than one hundred meters. Just enough to enclose the huge body of the lion-faced antelope and make some space.

Then there was the placement of those demonic power crystals, when dozens of crystals of the fourth-order single genus were divided into five elements one by one and placed in those grooves. Within this array, which Yue Yu himself named the Five Elements Gathering Spirit Array, a large amount of spiritual power had gradually begun to flow.

At this time, not only Ran Li and Lin Zhuo were dumbfounded, but Yue Yu's own mood was also agitated.

- This Five Elements Gathering Spirit Array, he was designed completely according to the spiritual power operation veins in his own meridians. Previously, although Yue Yu had continuously improved through the trumpet's formation test, he himself was not sure at all about the formation disk that enveloped such a huge area.

After settling his mind, Yue Yu put the last red demonic power crystal in his hand into the circular groove under his feet. Immediately afterward, the three of them saw that the spiritual power that was almost materialized began to flow slowly like water in the inscription dents in the array. And gradually connected as one, began the cycle of five elements.

Then, the spirits of heaven and earth, which were disgusting, rushed madly from the surrounding space. Enter the area shrouded in the disk. The spiritual power inside it surpassed the outside world more than ten times in an instant.

And at this time, Yue Yu was fixedly looking at the changes in the Lion-faced Antelope within the Five Elements Spirit Gathering Array,

All the fourth-level demon beasts on this Dongsheng Continent, after their demonic power reaches a certain level, their demonic power crystals will begin to form and usher in the Heavenly Tribulation. Those who successfully cross can be promoted to a fifth-order demon beast. Those who fail to succeed will die directly, or even have no bones left.

-- This is common knowledge that everyone knows in Yuejia City. And Yue Yu already knew about this as early as a year ago.

Therefore, after getting the Bingyi Bow in the clan, he came up with an idea, that is, could he use artificial methods to urge those fourth-order demon beasts to cross the tribulation?

However, there are two prerequisites for this, the first is whether this large Five Elements Gathering Spirit Array Disk designed by himself can operate normally and play a role. And then there are some high-level demon beasts, are they unconsciously absorbing the spiritual power around them, or are they intentional like humans?

The former of them now has an answer. Next is the next one, when witnessing the lion-faced antelope, suddenly let out a long howl, and began to absorb a large amount of spiritual power into the body between the mouth and nose, and then the wounds on the limbs poked out a trace of flesh buds at a speed visible to the naked eye, and then quickly healed the scene. Yue Yu's heart relaxed a little, and there was a little more self-deprecating smile at the corner of his lips.

In the past few months, the clan has been paying attention to the progress of his cultivation all the time. And relying on the existence of the Pei Yuan Pill and the imitation strong marrow, Yue Yu could barely maintain a considerable cultivation speed. However, as the effect of the drug gradually wears off. One day, the rulers of the clan will lose patience with him.

At that time, the clan might not have turned its face, but if Yue Yu wanted to have the same level of support as he did now, it would be impossible. And this number of high-grade demonic power crystals as high as fifty, as well as the array disk of this Five Elements Spirit Gathering Array, were far beyond the limit of his own burden.

So this time, even though it was his first experiment, it could also be the last! For him, it was only a success, not a failure. Success is a smooth road ahead, and defeat means that he can only be trapped in his current strength within five years!

The four wounds healed, and the lion-faced let out a roar and staggered to its feet. However, the Secret Talisman Arrow, which was trapped in the joint, never succeeded. And under the anger of the lion-faced antelope, the speed of absorbing the spirit of heaven and earth has become faster and faster.

At this time, Yue Yu's nerves tightened again, and the secret talisman arrow in his left hand had also been rewound. What he will face next is two other uncertain factors.

――Due to the state of spiritual power cycle transformation, the consumption of those demonic power crystals in the Five Elements Spirit Gathering Array is limited. However, at the current rate, within three hours at the latest, the Spirit Gathering Array would be ineffective.

And although this lion-faced antelope is already the oldest demon beast he has selected in the past few months, and has all five elements. But during this period, whether it could reach the limit of its own evolution, Yue Yu himself was not sure.

And then all around, there were already bursts of restless roars. With such a huge spiritual power frenzy, it was impossible not to attract the attention of other fourth-order demon beasts in this area. Although after the demon beasts reached this level, they attached much more importance to the concept of territory than ordinary beasts. But when they get agitated to a certain extent, no one can predict what will happen next.

The only thing Yue Yu was glad about was that the lion-faced antelope in front of him, with its huge body and the genus of the median beast, was an existence similar to an overlord in this area. No matter how uneasy the other demon beasts were, they wouldn't easily cross the line in a short period of time.

As time passed, the lion's body seemed to grow larger. In the sky, dark clouds suddenly began to gather without warning. By this time, not only the roar around them began to turn from agitation to panic, and then gradually fell silent. The three dragon-scale horses and camel beasts desperately tried to break free of the reins, preparing to flee into the distance. It was only because Yue Yu had tied the rope extremely tightly before that he would not escape. And in the end, he simply fell to his knees trembling all over.

Even the behemoth beast in front of a few people gradually diverted its attention from the three of them, and stared at the sky with a pair of huge eyes as if they were facing a great enemy.

As for Yue Yu, on the one hand, he completely wiped away the pressure he had accumulated in the past few months. On the other hand, it is still a little bitter in the mouth, and there is a slight rusty taste, which permeates the mouth.

-- The black cloud was getting lower and lower, and a flash of thunder flashed in it, not only the lion-faced antelope in the array, but also the danger. Even he, who was watching from a distance hundreds of meters away, was also subjected to the tremendous oppressive force.

And right behind him, although Lin Zhuo and Ran Li were standing upright, a trace of blood had escaped from the corners of their lips.

"This is the thunder tribulation of the fourth-order demon beasts? It is really terrifying and terrifying! In this way, when those books say that the sixth-order demon beasts cross the tribulation, the words often affect hundreds of miles, but I am afraid that they are not lies!"

Yue Yu's face turned a little pale, he never thought that this so-called thunder tribulation would have such a vast power of heaven and earth. The first is a strong storm that swept over the side with the lion-faced gazelle as the center. Immediately after that, the spirit of heaven and earth around him also began to shake from the inside out. Even with the true qi that affected his body, he was also rioting for a while. It takes all your strength to barely suppress it.

But the most frightening thing is the great pressure from the spiritual level, which makes people almost want to kneel down and surrender to this Tianwei.

And just when Yue Yu gradually felt a pain in his brain that seemed to be about to crack open. In the sky, the first purple thunder finally hit directly!

ps: The third more!
