This mysterious formation covers an area of more than a mile, and the formation is mainly black, mixed with a few other colors, and it is a special underground structure before it is activated. As soon as it was activated, a large number of runes immediately appeared on the surface of this formation, which covered an area of more than a mile! The runes were golden, containing endless mysteries, and the golden lines were a little dazzling. And this rune attracts space.

"Boom. "The terrifying waves soared into the sky, and the rocks and dirt above all turned into nothingness, and the 'pillar of light' with a diameter of more than a mile forcibly tore out a huge black hole in mid-air.

A black hole vortex, connected to another world from afar.

Qin Yun, who was originally trapping the Eagle Tiger Heavenly Demon while using the Smoke and Rain Sword to attack the sect's main hall, his face changed when he saw the terrifying fluctuations erupt and the huge black hole vortex appeared instantly.

This pillar of light is too powerful!

The black hole vortex is also too big!

"World Channel?" Qin Yun was incredulous, "World Channel, generally expands step by step from weakness, how can this just appear, so huge and stable?"

At the beginning, He Qian also used the World Altar to open the World Channel, because it was solved quickly, and in the end, the World Passage could not let the Yuan Shen Realm enter and exit!

"This world passage is much stronger than the one He Qian opened, enough to allow the Yuan Shen Realm to enter and exit. Qin Yun opened the Eye of Thunder and looked at the mysterious formation that was exposed underground, "I didn't expect that there was such a big formation hidden in the ground of the Barbarian Ancestor Sect. ”

Qin Yun also knew a lot of secrets.

Like the World Passage, it is normal to open a small World Passage, like a, and first make an anthill! The so-called 'embankment of a thousand miles is destroyed in an anthill', as long as no one obstructs it. You can continue to expand this 'anthill', so that it will continue to grow larger, and it can accommodate the first level of the Yuan God Realm and the second level of the Yuan God Realm...... Expanded to the extreme, it is enough to accommodate ordinary Heavenly Demons in and out!

However, this method is relatively slow.

The further back you go, the slower it gets, and if you want to expand a world passage that accommodates the Heavenly Demons in and out, I'm afraid it will take a month!

Another way -

The advantage is that it opens instantly, but the disadvantage is that the cost is too great. If it is a world passage that accommodates the Heavenly Demons in and out, it must be opened in an instant, and the price paid must be worth several high-grade spiritual treasures! Conquer a small world, although the harvest is great. But it's not worth paying the price of a few top-grade spirit treasures just by arranging the array.

Unless there is a special reason!

"At the beginning, the large-scale world passage was opened, and it was because I attacked the Barbarian Ancestor Sect that I forced them to launch it in advance. Qin Yun said secretly, "If they are given enough time, it is estimated that the world passage that can be opened will be even bigger?"

Thinking of this, Qin Yun shuddered a little.

Thankfully, they were able to launch it early.

......

Outside the Barbarian Ancestor Sect, the water mirror also showed the pillar of light that the mysterious formation soared into the sky, as well as the huge black hole that was torn apart.

The Bai Family Ancestor, the Divine Heaven Daoist Patriarch Zhang, the Human Emperor, the Maha Bodhisattva, the East China Sea Heavenly Dragon, and the Heavenly Demon Palace Master, the six of them looked at it solemnly, and when they saw the stable large-scale world channel, they all understood.

"Fortunately, Qin Yun came to the Barbarian Ancestor Sect and made them activate the formation in advance. The Bai Family Ancestor's voice trembled slightly, "The enemy has such a great courage, if they are properly prepared, once it is launched, it will be a great catastrophe." ”

Patriarch Zhang nodded: "Those who can afford to arrange such a formation are definitely not ordinary Demon God Emperors, looking at the prototype of this formation, the original plan was to arrange a world passage for ordinary Heavenly Demons to enter and exit." If it weren't for this attack on the Barbarian Ancestor Sect, decades later, perhaps when the World Passage was opened, a large number of Heavenly Demons would have killed in large numbers. ”

"Although the world passage of the small world can only allow the Heavenly Demon Triple to enter and exit at the most. Mahabodhisattva also said, "But once there are more of them, with the battle array, nine times out of ten, we will lose." ”

"No, the enemy should know that I am a disciple of Dao Ancestor. If I ask the senior brother of Biyou Palace to help me come to Dachang World at any cost, I can completely protect Dachang World. Patriarch Zhang frowned, "And to arrange the formation to accommodate the entry and exit of the Heavenly Demons, it will cost several high-grade spirit treasures. Conquering a small world is simply not worth so much. The enemy must have a special reason for doing this. ”

"What are you killing for?" the Maha Bodhisattva was also puzzled.

And at this moment—

"Wow~~~"

An extraterritorial demon god crawled over from the black hole whirlpool, his six thick arms full of scales stretched out first, grasping the world membrane wall, and his whole body barely got into the Dachang world.

"There are still too many flaws in the formation. As soon as this extraterritorial demon god climbed in, he immediately swooped down to the mysterious formation below, took out the materials from the Qiankun bag on his waist, and began to quickly complete the formation.

"Boom~~~"

Qin Yun manipulated the Smoke and Rain Flying Sword to attack this pillar of light with a diameter of more than a mile.

The misty pillar of light shelters the mysterious formation and the black hole vortex. No matter how Qin Yun manipulated the Natal Flying Sword to perform many sword moves, he couldn't shake this pillar of light.

"In terms of defensive means, this pillar of light is stronger than any other formation of the Barbarian Ancestor Sect. Qin Yun was anxious.

"Hum. ”

The pillar of light, which was more than a mile in diameter, expanded violently and spread in all directions.

Soon, the nearby sect hall was wrapped in, and the barbarian ancestor sect leader, monkey ancestor, sheep's horn old demon, and other demon gods and disciples in the sect hall rushed towards the mysterious formation one by one.

"Damn it!"

The remnants of the Barbarian Ancestor Sect all hid within that mile or so. The pillar of light retracted back into its original range.

And Qin Yun continuously cast the Smoke and Rain Sword, attacking dozens of swords, but he couldn't do anything.

"We're safe. All the disciples of the Barbarian Ancestor Sect showed joy.

The three of the Barbarian Ancestor Sect Master, the Monkey Old Ancestor, and the Sheep's Horn Old Demon collided with each other's eyes, and quietly transmitted: "We were trying to survive before, but we all tore our faces!"

"If you disobey the emperor, once the Demon God World has a chance, I'm afraid they will kill us. ”

The three of them were extremely careful.

It's struggling to survive in the cracks.

"Hurry, hurry, hurry. "The six-armed extraterritorial demon god was the first to come in, he was already good at the formation, and he was completing the formation at the moment, "Although the materials used now are much worse than the original plan, as long as they are completed, it will be easy for the Triple Heaven Peak Demon God to enter and exit." The emperor's goal is still hopeful. ”

"Wow~~"

Another extraterritorial demon god, from the black hole whirlpool climbed into the Dachang world with difficulty, obviously it is not easy for these triple heavenly demon gods to enter and exit now.

Seeing this, Qin Yun couldn't help but send a message to the Divine Heaven Dao people and human emperors in the outside world.

"Senior Zhang, what now?"

......

Outside the Barbarian Ancestor Sect.

"Do you want to use that treasure now?" said the Human Emperor softly, and the Bai Family Ancestor and the others also looked at Ancestor Zhang.

The Dachang world, which can resist the infiltration of the demon god world everywhere, is much deeper than a barbarian ancestral sect.

Although there are a large number of mortal beings living in the Barbarian Ancestor Sect formation, the Heavenly Dao is limited, so they can't kill it now. It's really time for 'life and death'! The treasures of the Zhen Clan are really used, and they also have a way to destroy a barbarian ancestor sect.

"If you don't live and die, you can't use it, even if you kill three or five heavenly demons, it's not worth it to use the Zhen clan treasure. Patriarch Zhang said, "The situation is really not good, I'd rather go and beg the senior brothers of Biyou Palace to go, than use the treasures of the Zhen clan." ”

Lingbao Tianzun has no class of teaching, and there are tens of thousands of disciples! Patriarch Zhang is a very inconspicuous one of them, and his status is also low. Even if you go to ask for help, the brothers will generally not take care of it! But there are a lot of brothers, and if they ask for more, there will always be someone to help.

It's just that with Patriarch Zhang's arrogance, unless he is really forced to do nothing, he will not ask for people like this.

......

"Qin Yun, you don't need to care about those demon gods now, go all out to destroy the Barbarian Ancestor Sect formation, destroy it as soon as possible, so that we can come in. The sooner you come in, the better! Patriarch Zhang's voice came from the transmission treasure, with a hint of eagerness.

Qin Yun held the summons order.

"Don't worry, leave it to me. Qin Yun responded.

On the side, Yi Xiao said: "But now that the Eight Doors Demon Sword Formation is still interfering with the side, there are other formations that will also obstruct it, and it will be very troublesome to break the formation." ”

"I can't take care of it, it's just that the Eight Demon Sword Array can stop it. Qin Yun said, his left hand stretched out, but there were two bright rays of light in his sleeve across the sky, this was a pair of super grade flying swords that Qin Yun specially bought through Ancestor Zhang before coming to attack the Barbarian Ancestor Sect this time.

Named 'Mandarin Duck Flying Sword', one is a female sword and the other is a male sword, all of which are super flying swords.

Qin Yun now wants to manipulate the Qiankun Ring to trap the Eagle Tiger Heavenly Demon, in this case, it is already the limit to manipulate the Mandarin Duck Flying Sword, the Natal Flying Sword, and the Aoba Flying Sword at the same time.

"Porphyry. Qin Yun took out the jade bottle from his arms, and a nine-turn spirit pill flew out, and immediately swallowed it in his mouth, recovering his soul spirit and restoring the mana in his body.

"Fight. ”

The Smoke and Rain Flying Sword, the Mandarin Duck Flying Sword, a total of three flying swords, crossed the sky, and went to break the formation respectively.

"You barbarian ancestors, stop them. The six-armed extraterritorial demon god who was in the formation shouted, "Now you can't let the Shenxiao Dao people come in." ”

"Rest assured. ”

The Barbarian Ancestor Sect Master, the Sheep's Horn Old Demon, and the Monkey Old Ancestor didn't dare to slack off, and they all manipulated the formation to obstruct Qin Yun's three-mouth flying sword respectively.
