The ice is constantly broken, and the threaded cone is like an electric drill, constantly tearing the ice, but the hardness of this ice layer is no less than that of steel, and the propulsion speed of the threaded cone is reduced at a speed visible to the naked eye.

Most of the ice was penetrated, but the threaded cone also stopped, and it was no longer able to move forward, Dong Yuanyuan had a disappointed face that could not be concealed, this attack was already her full attack, but there was still no way to break through the protection of this fierce beast.

Wu Aotian looked at the threaded sharp cone that had been recalled by Dong Yuanyuan in vain, and he couldn't help but feel a shock in his heart, this big guy was really too powerful, Dong Yuanyuan couldn't completely break through that defense by relying on the blow of the medium-grade spirit weapon!

Behind the ice, the beast's mouth cracked slightly, revealing an extremely human expression, as if mocking the incompetence of the two.

Wu Aotian looked at the ice that had been broken through most of it, and his heart was ruthless, a ball of spiritual energy gushed out, and instantly merged into the Demon Spirit Shield in front of him, his hands were staggered, and the Demon Spirit Shield had suddenly changed direction, from straight erection to horizontal horizontal flying, and a sharp blade stretched out from the edge of the edge, spinning wildly, and rushing towards the ice that had been broken most of it again.

Dong Yuanyuan's eyes, which were originally full of disappointment, suddenly burst out with a light of hope, and she didn't expect that Wu Aotian's spiritual weapon turned out to be an offensive and defensive one, not only as a shield defense, but also as an offensive spiritual weapon to make a powerful attack.

Dong Yuanyuan quickly retracted the threaded cone, adjusted the aura of the Linghai, and suddenly spewed out, attached to the threaded cone again, and rushed out again.

In just such an instant, Wu Aotian's demon spirit shield had already hit the ice hard, and it happened to be the position that Dong Yuanyuan had attacked just now.

If Dong Yuanyuan's threaded tip cone is like a crazy electric drill, then Wu Aotian's Demon Spirit Shield is a gear that is also spinning wildly.

The Demon Spirit Shield hit that huge pit, and the already shattered ice layer instantly intensified the speed of the rupture again, and in just an instant, the Demon Spirit Shield completely collapsed this thick ice wall with a strong aura in an instant.

The beast seemed to be taken aback, the banter and ridicule in its eyes were completely gone, and it actually retreated towards the rear with some fear, but the demon spirit shield had already broken through the ice and cut directly towards his slender neck.

The beast's neck shrank, and at the same time, a low roar came out of its throat, and a cloud of spiritual energy erupted, condensing into a cloud of gas like water mist, blocking the front of the demon spirit shield.

The Demon Spirit Shield slashed straight into the mist, and the mist suddenly cracked a gap, and the Demon Spirit Shield cut in, cutting a deep mark on the beast's neck, but the mist was like a dust swamp, making the Demon Spirit Shield sink deep into it, and the speed of rotation decreased sharply.

Wu Aotian sighed in his heart, and took back the demon spirit shield with a wave of his hand, and at the same time, the five Seven Killing Swords had already rushed out like ghosts, and in front of the Seven Killing Swords, Dong Yuanyuan's threaded sharp cone had already rushed over frantically.

The Demon Spirit Shield cut the beast's neck, although it was not a fatal injury, but this injury made the beast completely fall into madness and rage, and its eyes suddenly became as red as blood, leaving only endless anger and thick murderous intent in it.

The threaded tip cone came in an instant, but the fierce beast had already breathed down, a ball of spiritual energy erupted, and cold frost crystal particles instantly formed in the surrounding air, and on the ground, at a speed visible to the naked eye, a thick layer of ice extended out in all directions.

The wide deep pool turned into a thick layer of ice in an instant, and the entire huge cave in the belly of the mountain seemed to have become a world of ice and snow in an instant.

The threaded tip cone hit the aura head-on, like a piece of paper that was blown away by a violent explosion, and it swept back in an instant, and it was even a little out of Dong Yuanyuan's control, which showed how huge the power was.

Wu Aotian saw that the momentum was not right, and the Seven Killing Swords turned a corner, avoiding this aura one after another, turning back, falling from the air with endless blazing brushes, and the brushes were inserted into the ground, and the endless scorching heat instantly made the surrounding temperature extremely dry and hot, and the speed of the ice that spread over instantly slowed down a lot.

Dong Yuanyuan also retreated quickly, her body seemed to be surrounded by a gust of wind, and the endless wind flow rippled on her body, like a layer of armor, helping her resist the impact of aura.

The extremely cold aura continued to devour the scorching heat emitted by the Seven Killing Sword, and a strange scene appeared in the entire cave, in the vast ice and snow world, a blazing fire blocked the cold ice and snow invasion for Wu Aotian and Dong Yuanyuan, just like the last bit of fire in the ice and snow world.

The firelight quickly faded, the ice continued to extend, Wu Aotian reached out and summoned the five Seven Killing Swords back again, and the Demon Spirit Shield rushed out again, also with a blazing firelight, deeply penetrating into the ground, blocking the extremely cold ice qi that followed the two of them again.

"Woo......"

The beast let out a low roar and strode towards this side, and several more ice balls appeared in the air, and smashed towards this side at the same time, like missiles.

Wu Aotian and Dong Yuanyuan retreated in embarrassment, and there was a dull crashing sound in the cave, and the entire cave was already covered with ice, as if they had suddenly come to a cave in an extremely cold region.

Dong Yuanyuan looked at the fierce beast that was getting closer and closer, turned his head and shouted at Wu Aotian: "I can't escape, I still have a magic crystal divine thunder here, if the magic crystal divine thunder can explode against its body, we still have hope." ”

"Demon Crystal Divine Thunder?"

Wu Aotian's eyes lit up, the power of this thing, he heard Liu Ruxue say, the higher the level of making the magic crystal divine thunder, the greater the power, and it is simple to use, you only need to throw it out heavily, once it encounters a strong collision, it will explode violently.

"Okay, you throw it out and blow it up, even if you can't blow it up, it's good for us to take the opportunity to attack, by the way, and the metal cylinder spirit weapon you used before, you can also try it." ”

Dong Yuanyuan nodded, with one hand, there was already a black fist-sized thing in his hand, and handed it to Wu Aotian: "Demon Crystal Divine Thunder, you come and throw it, I will use the Spirit Killing Tube...... The closer you are to the center of the explosion, the more you will be injured, and it is best to break through its defenses before exploding, otherwise, I am afraid that the power will be reduced by the majority. ”

Wu Aotian took the Demon Crystal Divine Thunder, and his body quickly rushed towards the darkness, shouting, "Be careful yourself." ”

Although Dong Yuanyuan didn't know what Wu Aotian was doing, he also knew that he was trying to throw away the magic crystal divine thunder, and she also took out the spirit killing cylinder herself, and the spirit weapon needles inside had all been installed, a total of seventy-two in a tube, and all of them shot out with amazing power.

As soon as Wu Aotian entered the darkness, he restrained the aura of his body, as if his whole person had evaporated from the air in an instant.

He knew that he wanted to completely conceal the aura perception of this murderer, I am afraid it would be very difficult, but now the aura fluctuations in the entire cave are extremely strong, and after he has converged his breath, the aura fluctuations have become quite weak, and in such a battle, it is still very advantageous to hide himself.

The fact is just as Wu Aotian guessed, Wu Aotian quickly hid in the darkness, hiding behind a boulder, the fierce beast suddenly became a little puzzled, how did he feel that there was one less person?

Although the eyes of the fierce beast can roughly see the scene in the cave, after all, this cave is full of scattered boulders, and everywhere is a place that cannot be seen directly by the line of sight, Wu Aotian disappeared very suddenly, so that this fierce beast couldn't even find Wu Aotian's location all of a sudden.

Dong Yuanyuan dodged two ice bombs one after another, but he was still affected by the energy of the ice bombs, a thin layer of frost was attached to his body, and his body was not as flexible as before, this was only affected by the aura, not a frontal hit, if he was hit head-on, it is estimated that he would be directly shattered and turned into ice slag.

The fierce beast chased for another distance, but it was already close to Wu Aotian's location, Wu Aotian estimated the distance in his heart, and then looked at Dong Yuanyuan, who had been chased and had no way to escape, and knew that he couldn't wait any longer.

The body suddenly shot out, and the magic crystal divine thunder held in the palm of his right hand had been thrown out by Wu Aotian's splitting hand, the speed was extremely fast, the force was extremely fierce, and at the moment of throwing, Wu Aotian's body had suddenly rushed out frantically towards the front.

Dong Yuanyuan, who was next to him, saw the moment Wu Aotian rushed out, and at the same time frantically retreated to the rear.

The two of them hadn't retreated far before the Demon Crystal Divine Thunder had already slammed into the aura shield on the beast's body, and then exploded.

It was like a few tons of explosives suddenly exploded, and a huge fire rose from the place where the burst, and the huge beast fell into the firelight, and the whole huge cave was trembling violently, and large stones flew everywhere, and gravel and soil continued to fall on the top of the mountain, as if it was raining, as if the cave could collapse at any time.

Wu Aotian was swept away by the huge energy of the explosion in an instant, although Wu Aotian had already swung out the Demon Spirit Shield in time to block behind him, but the huge energy still swept him away with the Demon Spirit Shield in an instant, hit the stone wall heavily, and then smashed down.

Dong Yuanyuan is not much better, fortunately, she is a little farther away, and she has always been prepared, she lay on the ground in time, and used her aura to protect her whole body, although there are constantly gravel and dirt falling on her, but it can't cause her big damage.

As soon as Wu Aotian stood up from the ground, the Demon Spirit Shield flew up again, blocking the energy of those flying boulders and aftermath for himself, opening his mouth and spitting out a mouthful of blood, but his eyes were straight ahead, looking at the fierce beast wrapped in flames.
