Chitian and Mu Xiaotian have been fighting for so long, and no one can help each other, and most of the means have been used. The giant god stacked with rubble, and the thunder god idol gathered by thunder, have fought for dozens of rounds.

The power of the earth, the meteorite falling from the sky and the gravity field, against the power of thunder, the thunder field with the five elements of thunder, collapsed the surrounding void, and the battlefield ground was beaten into a huge pit.

The two collided and fought, and the Heavenly Demon Sword and the Broken Sword collided together. Each time, the two of them will be knocked away at the same time, and after flying out, they will collide at the same time, and I don't know how many rounds.

At this moment, when Yin Tian was making tentative words to Ao Yan, the two of them collided, without caring about anything else, and the direction of the upward direction was just facing Yin Tian. So forcing Yin Tian to avoid it immediately, he didn't dare to make a move, Ao Yan had an immortal weapon in his hand, once he made a move on Mu Xiaotian, he didn't know how crazy Ao Yan would be.

And at this time, the momentum of Mu Xiaotian and Chitian was also enhanced to the highest, and when they collided again, the height of the flight exceeded the position of Yin Tian Ao Yan, and the accumulation was completed, and the great immortal skills of the two were used again.

This time, Chitian did not cast the previous Yin Yang Life and Death Knife, but the Heavenly Demon Sect's strongest immortal art Heaven and Earth Annihilation, this technique was still performed by the Dao Heavenly Demon Knife, and the huge spiritual light sword slashed, and everything under the knife would be destroyed.

"Heaven and earth are gone. Ao Yan shouted again.

"That's right, it's the heaven and the earth that have perished. Chitian Zong Genius, he integrated any technique into his own Dao intent, and used the Heavenly Demon Sword to exert the power of slashing silence, which was stronger than the Yin Yang Life and Death Knife. It depends on whether Mu Xiaotian will use his hidden means, if not, he will only end up losing. Back then, Ling Yifei Immortal Venerable lost a chip on this move. ”

Ao Yan shook his head and said with a sneer: "Yin Tian, it's really funny that you are still a quasi-immortal, you would actually say such a thing, no wonder you can only rank third in the Heavenly Demon Sect, maybe in the future, Gu Yan's demon head and Sikong Wuliang will surpass you." ”

"What?" Yin Tian was very puzzled, but at this time, the power of Mu Xiaotian and the Red Sky Immortal Technique had already collided.

Mu Xiaotian still used the Nine Heavens God Thunder Technique, gathered the blessings of the five runes, filled the Dutian Thunder Seal, and used his strongest move Thunder Thunder to slash the past, evolving into countless thunder soldiers and thunder gods.

There was a loud bang, and the force collided to produce a recoil force, and it was not canceled out, and the remaining force continued to impact. With the last big battle matchup, the two have experience and it is impossible to get injured again. Each of them used the escape technique to avoid the side, although they still endured some of the remaining strength, but it was not enough to be seriously injured, and the combat power was still there.

"How could it be. Yin Tian shouted, unable to believe it.

"Huh...... Yin Tian, you still look at these demons with your own, it's too self-righteous. ”

"What do you mean. Yin Tian asked with a dark face. Kong Minghua on the side was also puzzled and looked at Ao Yan.

"This kind of demon can ascend to the immortal, it is not common sense to look at it. In them, there is no distinction between high and low spells of the same level, and the immortal arts do not look at which kind of immortal art is high and strong, but their own strength. You yourself have said that the Red Sky will merge the Heaven and Earth with the way of his own body, and the power released must be seen from himself. The strength of the two of them is equal, no matter what kind of immortal magic they cast, their strength is equal. The reason why the Immortal Heaven Demon Immortal was able to defeat Ling Yifei Immortal Venerable back then was due to his own strength, not the way of immortal arts, understand?"

"I've been taught......" Kong Minghua said respectfully to Ao Yan.

Yin Tian frowned, thought for a while and understood a lot, and bowed to Ao Yan to express his gratitude for his advice.

The two of them, who avoided the power of immortal magic, collided together again, continued to entangle the battle, and continued to climb to high places.

There are nine heavens in the fairy world, and the top of the nine is the real fairy world, and you can only enter the fairy world after breaking through the nine heavens, of course, there is a special way to ascend to the immortals, which is in Tianling Mountain, which is the passage between the fairy world and the mortal world, and you can enter and exit no matter what cultivation.

In ancient times, the Nine Heavens were separated from each other by a strong boundary wall, and only when the strength reached a certain level could they enter the next level. The Nine Heavens are also the place where the Supreme Mighty fight.

But the ancient heaven and earth have changed greatly, the nine heavens have been closed fourfold, and the six or seven ** heavy heavens have merged together because of this mutation, forming an isolation boundary wall that can block the immortal-level power, and it is difficult for the strong people in the immortal world to break through and enter the mortal world, and the passage of Tianling Mountain has also been blocked, and only true immortals can enter the immortal world from the mortal world.

The remaining five heavens are still the place where the supreme strong will fight each other, the higher the strength cultivation, the higher the place of the great battle, and quasi-immortals like Ao Yan Yintian will often choose the fifth heaven, where the space is strong enough to resist the power of quasi-immortals.

Now the Great War of Mu Xiaotian and Red Heaven is slowly about to enter a heavy heaven, and it is on the edge, and it is difficult to enter because of insufficient cultivation.

"The cultivation of the two of them is slowly improving, do they want to break through in the big war?" Kong Minghua noticed this.

"Of course, this is their last chance, and their future breakthroughs in cultivation will depend on comprehension and enlightenment, and it is impossible to break through in a great war. The current realm has broken through from the Great War, which is of great benefit to the two of them, and I don't know if it is advancing at the same time. Ao Yan explained.

"It's almost over, the two of them are only one step away from cultivating to break through the bottleneck. ”

Mu Xiaotian and Chitian both felt this, so they stopped at the same time and faced each other at the same time.

"It's just a little bit, this kind of collision and engagement is too slow, you and I will use immortal magic to duel again, and we can break this bottleneck under such pressure. ”

"Good...... Then it's time to see who breaks through the advanced first. ”

Each side of the party, at the same time, the strength of the force, Chitian still exerted the power of heaven and earth annihilation, Mu Xiaotian still did not come up with his own hidden spell, with the five runes to bless the broken sword to cast the Nine Heavens God Thunder Technique. At this time, the aura of the Kwai Water Phantom Thunder Rune was almost the same as the two Thunder Runes of Jin Mu.

Before they were exerted, they all felt the pressure on each other, and they continued to improve their strength. Just like just now, they collided together, but the two did not dodge immediately, but stopped for a few breaths to bear the pressure brought by the immortal arts. It's because he was a few breaths late, and when he finally dodged and resolved, he was injured and flew out upside down, but the injury was not as serious as that of Fenghua City.

Heaven and earth changed, Dao intent appeared, and pure spiritual power formed two vortices and sucked into the bodies of the two. The injuries were not in vain, and the realm of the two finally broke through at this moment.

"Sure enough, it broke through in the big war. Ao Yan and Yin Tian were overjoyed, and said at the same time, and flew up at the same time to catch Mu Xiaotian and Chitian respectively.

Aratto Tian and Kong Yiyan, who were fighting at the bottom, also sensed it. Aratoten was particularly unconvinced, and roared and shouted, "Ahhh......h Chitian's kid actually advanced as an immortal beast earlier, and he didn't accept it, so he didn't accept it. Silly Firebird, no matter how hard you exert your strength, this immortal beast will also break through to advance. ”

Kong Yiyan was not to be outdone, "Hmph...... Is your strength too weak, little black snake, what about your ultimate?"
