The original glow of the Inner Dan, after the thunder swallowing beast injected a large amount of spiritual power, the light suddenly flourished, and ten thousand rays of light shot out from it, illuminating the entire mountaintop, and the huge coercion covered the entire mountain, this momentum was many times stronger than the previous resistance to the three cyan thunders.

"Boom!"

With a loud bang, blue lightning struck Neidan, and the fluctuations of spiritual power collision exploded, sweeping in all directions, and a mountain was cut off and fell into the valley below, with a dull sound.

This is a confrontation with the power of heaven and earth, throughout the ages, only the thunder-swallowing beast that feeds on thunder and lightning dares to do so, if it is replaced by other creatures, under this blow, I am afraid it has already become a catastrophe.

Despite this, under the divine power of heaven and earth, the Thunder Swallowing Beast was not comfortable, and the Inner Dan was dim, only a small amount of electric arc wrapped around it, and it itself, under that blow, was smashed into the mountain.

The mountain cracked, this time, it was blasted into the mountain for more than ten zhang, the whole mountain was full of cracks, and a huge crater appeared in Yun Fei's mind.

After this blow, the dark clouds in the sky receded like a tide, and it was sure that under such a strong blow, the Thunder Swallowing Beast would definitely die. In an instant, the sky was clear again, the bright moon was in the sky, and the sparse stars hung in the sky.

"This is the moment!"

Yun Fei muttered to himself in a low voice, like an arrow off the string, and swept towards the Neidan suspended in mid-air.

Yun Fei endured the severe pain in his soul, did not retreat, he had already planned in his heart, taking the opportunity to cultivate his soul was just one of the purposes, when he saw the thunder swallowing beast twisting its body and dissolving the power of thunder, while secretly deducing and figuring it out, another thought also arose in his heart.

The idea of seizing the Inner Dan that contained the power of thunder was very bold, if it was before, Yun Fei didn't dare to think about it at all, but now it was different, after the bombardment of thunder and lightning, especially the strongest blow of the last blue thunderbolt, the Thunder Devouring Beast was already very weak, and even the vital Inner Dan did not have time to be included in the body.

"Whoosh!"

Like a sharp arrow breaking through the sky, with a sound that pierced the void, the true dragon in his body raised his head and roared, urging Yun Fei's speed to the extreme, he knew in his heart that in this trial secret realm, there were many people who were stronger than him, and there would definitely be many people who would come, so taking advantage of the favorable conditions closest to the Thunder Devouring Beast, he urged the speed to the extreme, and wanted to be one step ahead of others and grab Nedan in his hands.

The Thunder Swallower was battered and dying, and there was still blue lightning crackling on its body, wantonly destroying its flesh and devouring its vitality.

However, it did not die immediately, although its eyes were dim, it was also extremely excited, the sixth thunder was carried over, as long as it was raised for a period of time, and when the body recovered, it would leap out of thin air and enter a higher realm.

The huge head was raised with difficulty, looking at Neidan, who had been cultivating for many years, and his abdomen was squirming hard, wanting to suck Neidan into his abdomen.

Nedan moved, slowly flying towards the Thunder Swallowing Beast, as long as Nedan entered the body, it would quickly flee away, find a safe place to heal and recover from its wounds.

Unfortunately, it failed in the end, and when Neidan had just flown to the edge of the huge crater, the cloud flew to it, reached out and grabbed the Neidan, and was about to flee away.

As soon as he grabbed Neidan, Yun Fei's body trembled, almost knocking him to the ground, and the arc was wrapped around his arm, and one sleeve was shattered instantly, and even the long black hair was upside down by the lightning strike, as if countless steel needles were stuck all over his head.

Yun Fei was shocked, this is still the inner dan that has been greatly reduced after being bombarded by the blue thunder, if it is in its heyday, with this one, it will be able to smash Yun Fei, and he can no longer hold on to the inner dan, because the thunder-swallowing beast let out a miserable howl when he found that someone actually dared to rob/rob its inner dan.

The voice rushed straight to his soul, almost shattering his soul, and a trace of crimson blood flowed down the corner of his mouth, and he hurriedly threw Neidan into the disc space, a little ground, and swept into the distance.

He didn't dare to stay here for long, because in his mind, several figures were shooting towards here, and the speed was almost comparable to that of his Dragon Walk Nine disguise.

Moreover, Nedan suddenly lost contact with himself, which made the weakened Thunder Swallowing Beast furious, and I don't know where it got its strength, it suddenly stood up, jumped out of the giant crater.

At this moment, Yun Fei's figure was only a small black dot, which made the Thunder Swallowing Beast jump violently, it was the Inner Dan that it had cultivated for many years, and all the essence of its body was there, how could it tolerate others snatching it away.

At that moment, it roared, shattered countless boulders, dragged its huge body, moved its short and powerful limbs, and chased it down.

Despite its large size, its speed was not slow at all, and its limbs leaped into the air at a distance of a few feet, and the rocks and ancient trees along the way could not stop it at all, and under its brute force collision, they exploded and collapsed.

Those spiritual cultivators who came from other places happened to see this scene, although they had doubts and puzzles, but it did not hinder their determination to hunt for treasures, the moment they came to this place, the smell of barbecue in the void did not completely disappear, plus they saw that the thunder swallowing beast was covered with traces of lightning slashing, and the ** in their eyes became even stronger.

"Chase, can't let it escape!"

The white-robed young man let out a low cry and took the other two teenagers to chase after him first. There were several waves of spiritual cultivators who came to the Land of the Thunder Devouring Beast's Tribulation, and each wave was not too many, the most was no more than three, and the least was only one.

These people were all a group of more than ten people before, but the gap between those people and their cultivation was too big, and the speed was too slow, so they were left behind.

"He's been here too?"

Mu Tianxin stood on an abrupt rock, looking in the direction of the Thunder Devouring Beast in the distance, at this time, she used a piece of black veil to cover her shocking face, whispering to herself, her beautiful eyes turned, there was a fluctuation here, and the breath was familiar, because someone's green shirt was lying in her storage space.

She tiptoed a little rock and chased after the Thunder Swallower, because, at this time, several waves of people had already chased her, and she didn't want to miss this opportunity, so she chased after it.

Yun Fei in the rush, his powerful perception had already been released, avoiding the gathering place of many demon beasts, and he thought that he would escape smoothly after capturing Neidan, but there was a dangerous aura from behind, which made his hair stand on end.

In his mind, the Thunder Swallowing Beast chased after him like a whirlwind, thinking that under the blue thunder and lightning bombardment, the Thunder Swallowing Beast that had no chance of surviving was so violent, which was beyond Yun Fei's expectations.

Moreover, its speed is not slow, it is not weaker than the Dragon Nine Transformations cast by Yun Fei, and it is even a few points stronger, the distance between them is rapidly narrowing, from the original distance of thousands of zhang, the chase path is now less than a kilometer.

"Damn it!"

Yun Fei cursed in a low voice, his speed had been increased to the extreme, and he wanted to break through again, unless he could condense the true dragon in his body into a dragon claw, as long as that way, he could double his speed, but it was obviously impossible at the moment, even if he could condense the dragon claw, the Thunder Devouring Beast would not give him this opportunity.

The wind behind is getting closer and closer, from the original distance of a kilometer, now there are only less than five hundred meters left, it can be seen that in terms of speed, the huge Thunder Swallowing Beast occupies a certain advantage.

Yun Fei was puzzled, that huge size should be very clumsy, but the Thunder Swallowing Beast was good, completely subverting his cognition, not only was it not clumsy, but its speed was as fast as a tanuki, with such a speed, coupled with its size, even if it was a mountain range in front of it, it was estimated that it would be knocked into collapse.

There were many demon beasts along the way, they bared their teeth and roared at Yun Fei, and before they could attack, the pressure of their hearts pressed on them, making them tremble and tremble, their legs and feet were weak, prostrate on the ground, and their bodies trembled like chaff.

The Thunder Devouring Beast is too powerful, it is a ninth-order demon beast that condenses the Inner Dan, it is estimated that it is rare in the entire trial secret realm, it is an instinctive fear of the lower ones when they see the upper ones, they don't even dare to raise their heads, they are terrified.

Of course, there are also some demon beasts whose fate is not very good, blocking the way of the Thunder Swallowing Beast's pursuit, their fate is very miserable, either by the short and thick limbs of the Thunder Swallowing Beast, or by the giant tail into a blood mist, not even a complete bone was left, and they died unjustly.

The entire trial secret realm was boiling, and everywhere Yun Fei went, the birds and beasts were frightened, fleeing in all directions, the scene was quite lively, the roaring sound was constant, and the birdsong was endless.

The young geniuses who followed the Thunder Swallowing Beast were dumbfounded, not understanding what was going on in front of them, their speed was still a little worse than that of the Thunder Swallowing Beast, and they were left far behind by it, and they couldn't see what was going on in front of them.

However, this did not affect their determination to kill the Thunder Eater, because after chasing them down the way, they found that although the Thunder Eater was running like a tireless machine, the flesh that fell from its body was left all the way, some as black as carbon, and some as bright red.

Yun Fei also discovered this situation, because the Thunder Devouring Beast was getting closer and closer to him, and he knew very well that on his huge body, the flesh and blood in several places had fallen off, revealing Sen Bai's bones.

Not only that, the breath of the Thunder Swallowing Beast looked very strong on the surface, but it was not, he found that the breath of the Thunder Swallowing Beast seemed to be weakening, and if he continued to run wildly, he would get rid of the pursuit of the Thunder Swallowing Beast sooner or later.

However, Yun Fei, who was galloping, suddenly stopped, no longer far away, not that he didn't want to escape, but that the Thunder Devouring Beast was already approaching, only a zhang away from him, and it was the first to attack.

The Thunder Swallowing Beast swayed its giant tail more than two feet long, and in the process of rushing forward, it swept behind Yun Fei, with a strong wind, whining, and the ground was directly scraped off a layer deeply, and suddenly, dust flew, debris splashed everywhere, and a sandstorm blew on the flat ground.
