In the fourth heaven, Duanmu Xiaotian Chitian walked all the way to the position of the space boundary wall, counting the time of the mortal world, several days have passed.

As soon as he arrived at the position, he immediately used his strongest means to launch an attack on the spatial boundary wall. However, they need to resist the power of spatial turbulence, so it is extremely inconvenient to attack the spatial boundary wall.

After attacking for a while, the Chaotian Immortal Venerable stopped them and said, "There were still signs of being attacked on the spatial boundary wall before, why is there no now, could it be that the forces of mortal heaven and earth have given up on the two of you." Although it is easier to attack the spatial boundary wall from the outside to the mortal world, the current strength of the two of you is still not enough, and my strength cannot be used, so I can only bless and assist. But you two alone can't break the boundary wall, so you have to find a way. ”

"Since we can see the signs of attacking the boundary wall from the mortal world, then we can also see the signs of our attack in the mortal world, and they will definitely come to our aid and rescue us. Now all we have to do is keep attacking and attracting attention, and then the sect will definitely find a way to rescue. Ancestor, you still continue to bless me, you must open the boundary wall, otherwise you will really be trapped here. ”

"That's all there is to it. "Chaotian Immortal Venerable looked very helpless, and he knew that there was no good way, and the only sustenance was the mortal world.

But he didn't expect or underestimated the strength of Duanmu Xiaotian and Chitian. After the Chaotian Immortal Venerable blessed Chitian with all his might, Chitian showed all his strength. Now you can't hide your strength anymore, and if you continue to hide, you may lose your life.

Chitian also knew that Duanmu Xiaotian must have hidden his strength, so he didn't remind him, he believed that at this time, Duanmu Xiaotian would not continue to hide.

Duanmu Xiaotian was blessed by the Red Sky Thunder Immortal Stone, and he no longer cared about anything, and his own strength was fully displayed. Boom, thunder flooded out, covering an area of twenty zhang in the periphery, forming a thunderball.

Holding the Xuantian Broken Sword and dancing, the power of the seven thunderbolts appeared again, and the thunder ball was emitted with the power of thunder, forming a thunder cover, directly blocking the spatial turbulence that rushed towards the two of them, Duanmu Xiaotian continued to exert the power of thunder, and said to Chitian at the same time: "Brother Chi, you don't have to care about the turbulence in the space, get ready, and when I see the right time, I will join forces to attack the space boundary wall." ”

"Okay......" Chitian waited for Duanmu Xiaotian's words, and he had already prepared. After Duanmu Xiaotian used the power of thunder to block the spatial turbulence, Chitian ignored those spatial turbulence.

Around the perimeter of this spatial boundary wall, the power of the spatial turbulence is not very strong, and Duanmu Xiaotian exerts all his strength, which is enough to deal with it.

After dealing with Duanmu Xiaotian, he constantly sensed the characters and grasped the surrounding situation. Wait for the free time of the turbulent impact, and join forces with the red sky to shoot. A Nine Heavens Divine Thunder Technique, a Yin and Yang Life and Death Knife, jointly unleashed.

After so many years in the Immortal Spirit Heavenly Realm, the tacit understanding between Duanmu Xiaotian and Chitian was getting higher and higher, so the power of joining forces was extremely powerful, which shocked the Mixed Heaven Immortal Venerable. When two quasi-immortals join forces, the power they can exert is equivalent to the power of immortal magic used by Immortal Venerable.

After this blow attacked, the amplitude of the spatial boundary wall was even greater, and it seemed that there were cracks.

"There is a chance, continue to attack. Chaotian Immortal Venerable shouted, as if he saw hope.

Taking advantage of the situation, Duanmu Xiaotian Chitian responded to the attack of the spatial turbulence and attacked the spatial boundary wall with all his might, but it was only able to produce cracks. The healing degree of the spatial boundary wall is very fast, and after each attack, when the next attack comes, it will almost heal, so no matter how much Duanmu Xiaotian Chitian makes a move, he can't turn the crack into a crack, and he has suffered a lot of injuries for this.

"The three of us, if we join forces, we can't break the spatial boundary wall, and if we continue like this, we will be consumed by the spatial turbulence. Don't be in a hurry, attack slowly, the sect will definitely not give up on us, and we will be able to go out when they respond. Duanmu Xiaotian stopped such a suicidal attack, and every time he attacked once when there was no spatial turbulence, so as to avoid being injured by the spatial turbulence.

The cracks created by Duanmu Xiaotian's Red Sky joint attack can not only be seen in the Fourth Heaven, but also in the position of the boundary wall relative to the mortal world.

Since the Boundary Wall was attacked, all forces have used the highest means of exploration to probe the location of the Spatial Boundary Wall and found the crack.

"There is actually a crack, how strong is this Thunder Heavenly Demon Son. ”

Dao Xuanzong's side did not pay attention to the cracks, but was anxious why the wind and thunder did not make a move. If he didn't make a move, the supreme of Dao Xuanzong would have to go up and help.

"Don't worry, everyone, the wind and thunder must have sensed the location of Xiaotian a long time ago, so I said before that I would have to wait. If you don't make a move yet, you are probably waiting for the opportunity. Seeing that the supreme of Dao Xuanzong was about to move, Ao Shun immediately comforted and said, calming the hearts of Dao Xuanzong.

Not long after he finished speaking, a huge sound of hitting stones came out again from the Heavenly Wind Thunder Abyss, shaking the entire heaven and earth. Immediately, in the depths of the Heavenly Wind and Thunder Abyss, five thunder lights rose into the sky, and in the middle of the five thunder lights, you could see the wind and thunder running.

"Wind and Thunder have dispatched......" The Supreme who was waiting outside the Heavenly Wind and Thunder Abyss immediately delivered the news.

In the Nanling Immortal Cultivation Realm, a voice from the Demon Mist Heavenly Ridge also sounded, and its power was no weaker than the wind and thunder. A huge shadow flew out, and the Demon Desolation Snake also dispatched.

The two immortal-level brute beasts finally flew to the spatial boundary wall, dozens of miles away, facing each other from afar. Immortal-level brute beasts rarely meet each other, but now with the same purpose, they only meet together. After a short confrontation, the Wind Thunder Demon Desolate Snake looked at the crack one after another.

In today's mortal world, the power that immortal-level brute beasts can exert will not be too strong, and they will not be able to reach the power of the real immortal path, unless they are desperately exerted. The Wind Thunder Demon Desolate Snake struck one after another, and the power of the Wind Thunder and the Earth all attacked the crack. Its power is stronger than the previous joint efforts of various forces, and its effect only increases the crack.

Duanmu Xiaotian Chitian of the Fourth Heaven saw such signs, and the hope in his heart was even greater, but the power that the two of them could exert had reached the maximum, unless they attacked desperately. So for the two of them, they still have to wait for the rescue power of the mortal world.

On the side of the Heavenly Demon Sect, four quasi-immortals made a move, bringing three immortal weapons to support. On Xuanyan Mountain, Ao Shun rushed up with a water bowl, and two quasi-immortals on the side of Lingxiao Pavilion also made a move. On the side of the Tang Empire, Li Shangyin, who had become a quasi-immortal, flew over with the Longquan sword.

Of course, not only the quasi-immortals of these forces, but almost the entire world's quasi-immortal powerhouses rushed in that direction, wanting to make a contribution. However, some of the journeys are too far away, and even if they are blessed by immortal weapons, it will take a certain amount of time.
