After a brief observation, Duanmu Yu faintly felt that this space should be a retreat place for a certain master to practice the secret art of thunder and lightning.

Then, Duanmu Yu took difficult steps and rushed to the center of the main hall space, carefully observing the ground, and found that the hard rock floor in front of him was carved with extremely complex spirit array patterns.

Duanmu Yu has practiced the spirit array of gathering spirit arrays, imprisoning spirit arrays and other spirit arrays, and is no stranger to this kind of spirit array pattern, after observation, Duanmu Yu found the shadow of the spirit gathering array diagram from the complex spirit array pattern engraved on the ground, but the lines of the spirit array diagram carved out of this depiction are interspersed with the lines of other spirit array arrays, if you don't observe carefully, or people who are not familiar with the spirit array diagram, it is difficult to find this.

"The spirit array can still be used like this, and the line nesting entry point of each spirit array diagram is just right, which does not destroy the function of the original spirit array, and can well combine different spirit arrays to make their functions more powerful. From this, it can be concluded that this senior's attainments in the secret art of the Spirit Array are very human. In addition to admiring in his heart, Duanmu Yu put down all distracting thoughts, sat down cross-legged in front of the spirit array pattern, stared intently, stared at the complex spirit array pattern, carefully observed and studied, and tried to decompose this complex spirit array pattern.

After a day and a night of hard work, although Duanmu Yu was not able to completely decompose this complex spirit array pattern, he still benefited a lot from it, and he had a lot of new comprehension and understanding of the nested combination essentials and skills of the spirit array.

Moreover, he also memorized this entire complex spirit array pattern in his mind, and if he needed it in the future, he would be able to depict this spirit array diagram flawlessly for his own use and research.

At present, what Duanmu Yu urgently needs to do is to improve his strength and cultivation realm, after writing down the spirit array diagram, Duanmu Yu temporarily put down the study of this complex array diagram, slowly got up and moved to the center of the array, that is, if this array is stimulated and starts to operate, the spirit gathering array will sit cross-legged in the center of the center where the gathered power is directly released, and begin to try to activate this complex array with his own strength.

With the introduction of the power of the activation array, the array immediately began to operate, emitting a brilliant light, only reflecting the entire hall space in a dazzling light, stabbing people who couldn't open their eyes.

Of course, this refers to the case if someone is watching from the periphery of the formation.

Duanmu Yu, who was in the formation diagram, was not affected in any way, and the dazzling light did not cause any impact or discomfort to his vision, which was the magical effect brought by the hidden secret array nested in the operation array.

With the operation of the spirit array, Duanmu Yu, who was in the spirit array, clearly sensed that wisps of violent thunder and lightning power poured out from the spirit gathering array, rushing into his body, causing a great impact on his strong and perverted flesh and blood, as if he might collapse and disintegrate at any time because he could not withstand the violent power.

Fortunately, this mysterious spirit array seems to know the limit of the strength of the master's body that is controlling the spirit array, and when it infuses the power of thunder and lightning into Duanmu Yu's body, it has always been maintained at the limit that Duanmu Yu's body can bear, otherwise, the consequences are really unimaginable.

At first, Duanmu Yu was completely uncomfortable with the powerful impact of this power, and the feeling of his flesh and blood being torn apart made him feel extremely uncomfortable, and it was not until a quarter of an hour later that he gradually adapted to the feeling of this power washing through his body, refining his flesh and blood.

Half an hour passed, Duanmu Yu completely adapted to the power of thunder and lightning infused into his body by the Spirit Gathering Array, and clearly perceived that the refining effect of the power of thunder and lightning on his flesh and blood had completely disappeared, knowing that this was because his flesh and blood body was too perverted, and even the current level of thunder and lightning power could not have a refining effect on his flesh and blood, so he began to try to absorb the power of thunder and lightning and refine and condense the Lei Yuan Spirit Bead.

The condensation process of the Lei Yuan Spirit Bead was slow and complicated, but fortunately, at this moment, there was an inexhaustible power of thunder and lightning for Duanmu Yu to use, which made his condensation of the Lei Yuan Spirit Bead much smoother than before.

In the blink of an eye, three days passed.

After three days and three nights of hard work, after condensing a total of more than 100 Lei Yuan Spirit Beads, Duanmu Yu clearly found that the power of thunder and lightning gathered through the Spirit Array was decreasing at an extremely fast speed, until he completed the condensation of a Lei Yuan Spirit Bead on hand, the power of thunder and lightning was already so weak that it was almost negligible.

At this moment, the power of thunder and lightning that filled the space of the main hall disappeared out of thin air, and the rocky ground and rock walls, which had become incomparably hard due to the attachment of the power of thunder and lightning, became weak, and even appeared in some places with extremely clear cracks, as if they were in danger of collapsing at any time.

Rumble!

A loud tremor came from above.

Then Duanmu Yu clearly noticed that a large number of stone chips and dust were constantly falling down, and the originally small cracks on the top wall were slowly growing larger at a speed visible to the naked eye, and they seemed to be pressed by heavy objects and were falling downward.

"Oops, the space is collapsing, it's better to get out of here. Seeing the scene in front of him, Duanmu Yu hurriedly got up, jumped up, passed through the crack that was torn open by the top wall, and then smashed his fist again and again into the huge stone that flew towards him, blocking his path.

These stones were originally extremely hard, and his fists were difficult to shake.

But right now, the stones that flew towards him were like the difference between stones and tofu compared to his fists.

At the slightest touch, the stones that blocked his path turned into splinters.

Roar!

Just when Duanmu Yu rushed out of more than 100 zhang, and was about to rush out of the rocky falling area, and returned to the ground, there was such a shocking beast roar from where his vision could not reach, and then he captured a powerful breath of life, and then he clearly sensed an incomparably huge devouring power swept up and down.

The boulder and dust debris that were originally falling changed their trajectory due to the sudden appearance of the devouring power, and immediately reversed and flew towards the source where the devouring power was released.

Duanmu Yu, who was rushing upwards, was suddenly attracted by the devouring power, and the speed of the rush increased sharply, until he rushed more than ten zhang away, realizing that the situation was not good, and then he cast a spell to reverse his body shape and fight against the devouring power, intending to break free from the devouring power.

At this moment, it is unleashing the power of devouring, intending to devour Duanmu Feather is the Thunder Devouring Beast, one of the powerful beast creatures in this area.

The Thunder Swallower feeds on thunder and lightning, and every time it swallows an extra mouthful of the power of thunder and lightning to digest it, its combat power will increase by one point, thus making the Thunder Swallower label a strong person in this kind of creature that feeds on the power of thunder and lightning.

The Thunder Poison Beast, and the Thunder Beast compared to the Thunder Devouring Beast, are completely incomparable in combat power.

Even if it is a young Thunder Swallowing Beast, a Thunder Poison Beast, a Thunder Beast and other creatures do not dare to provoke easily, it is a person at the consummation level of the Human Soul Cultivation Realm, when they see the cubs of the Cloud Swallowing Beast, they have to retreat, and the power of the adult Thunder Swallowing Beast is even more terrifying, and the people who cultivate to the realm below the Human Cultivator Creation Realm, those who see their faces, have no life, and they have all become things in its stomach.

The spirit of the thunder swallowing beast is extremely high, but there is no way to refine the power of thunder and lightning by casting its own spell to condense the thunder element spirit bead, and now because the power of thunder and lightning in this area has suddenly weakened, and it has clearly captured the breath of the thunder element spirit bead in this area, and has traced it all the way to this point, only then did it know that Duanmu Yu was the person who caused the power of thunder and lightning in this area to weaken, and also captured the breath of the thunder yuan spirit bead from him, so as to lock Duanmu Yu, intending to devour him and seek to rob him of the power of the Lei Yuan spirit bead contained in his body.

The Thunder Devouring Beast that was releasing the power of devouring, when Duanmu Yu cast a spell to resist, it could clearly perceive it, and naturally it would not easily let go of the target it was targeting.

So, at this moment, it increased the release of the devouring force, and it was concentrating on Duanmu Yu.

Sensing that the devouring power that enveloped him suddenly increased, the body that had been able to slowly move outside the area covered by the devouring force moved irreversibly with the devouring force again.

"Originally, I didn't plan to do much, but since you are looking for death, then I will fulfill you. Realizing that the Thunder Swallowing Beast would not let him go easily, Duanmu Yu simply turned his heart sideways, regardless of the loss of property, cast a spell to urge the power of the Devouring Treasure Gourd, unload the pressure on himself, and slow down the pace of moving towards the Thunder Swallowing Beast, while secretly urging the glazed treasure bowl, throwing out a part of the thunder fire beads stored in the bowl, mixed with the stones and dust that flew towards the Thunder Swallowing Beast, and smashed into the Thunder Swallowing Beast.

Duanmu Yu's behavior was very hidden, coupled with the limited intelligence of the Thunder Devouring Beast, and his vision was hindered to a certain extent at the moment, he didn't notice that a large number of Thunder Fire Beads were flying towards him along the devouring power at this moment, but through perception, he sensed that the power released by Duanmu Yu to fight against it had increased, which stimulated its fighting spirit.

At this moment, it did not realize that the danger was approaching, and it actually increased the release of the devouring power again.

Whoosh!whoosh!whoosh......

The large number of thunder fire beads thrown by Duanmu Yu, without exception, were directly thrown into the mouth of the Thunder Swallowing Beast in a very short period of time, and smoothly entered the belly of the Thunder Swallowing Beast.

Then there was a series of dull bangs that rang out in the belly of the Thunder Swallower.

As a result, the devouring power that swept through the area in front of him disappeared, and Duanmu Yu took advantage of the disappearance of the devouring power that bound his body, and quickly cast the ghost shadow concealment secret technique to stay away.

The Thunder Swallowing Beast's belly, at this moment, under the effect of the impact force generated by the explosion of the Thunder Fire Bead, expanded rapidly like a balloon, and the power of thunder and lightning that was originally stored in the Thunder Swallowing Beast's body slammed out from its flesh and blood, releasing lightning rays that swept all around, only submerging and destroying the nearby space within a radius of 100 zhang, turning into nothingness.

Duanmu Yu, who was outside the Qianzhang area, saw the scene in the area where the Thunder Swallowing Beast's body was located, and immediately gasped, and secretly exclaimed in his heart: "Fortunately, I acted decisively, if I delay even a few more breaths, I will be closer to the body of the Thunder Swallowing Beast, and at this moment, I am afraid that I have been torn to pieces by the terrifying power released by the Thunder Swallowing Beast."
