Just as Li Wenyuan and the other three were running around in the entire Immortal Cultivation Realm for the sake of this evil magic gate, at this time, in the extraterritorial battlefield of the Immortal Cultivation Realm, the battle was unprecedentedly difficult.

At the extraterritorial battlefield, countless extraterritorial demons at this time are now attacking the defense line of the Immortal Cultivation Realm. However, unlike before, the attack method of the extraterritorial demons was not to send a large number of cannon fodder to death first, but as if they were the same as the immortal cultivation world, they had strict organization and discipline, formed a battle formation, and attacked the defense line of the immortal cultivation world.

The immortal cultivators were simply stuffy, they were very aggrieved, and they couldn't believe that the one who was fighting with them today was still the previous extraterritorial demons.

Countless extraterritorial demons have used all kinds of spells, far away attacking the outermost formation of the extraterritorial battlefield of the Immortal Cultivation Realm, and under the continuous and high-frequency attacks, the immortal cultivators who are responsible for maintaining the formation can only do their best to stabilize the formation.

A warship dispatched, and all kinds of spells formed a torrent, pouring towards the side of the extraterritorial demons, but it was firmly blocked by the formation arranged by the extraterritorial demons, so that this effective attack used to clean up the miscellaneous fish in the past could not play any role now.

"The situation is not good, hurry up and notify the Demon Slayer City and ask them to send reinforcements as soon as possible. Seeing that the situation was not good, the Yuan Shen True Immortal, who was in charge of guarding the extraterritorial battlefields of all parties, immediately reflected the situation to the Demon Slayer City.

The Yuan Shen True Immortal in the Demon Slayer City received urgent reports from the Quartet Battlefield one after another, and all of them did not dare to slack off, and sent reinforcements to the Quartet Battlefield one after another, but soon received an emergency from the Quartet Battlefield.

In the end, he could only report the situation to Chu Huaigu and let Chu Huaigu make a decision.

Hearing that the people below came to report, Chu Huaigu just sighed faintly, "This day is finally coming!"

For today's situation, Chu Huaigu had actually expected it in his heart. As the most powerful enemy in the Immortal Cultivation Realm, the Extraterritorial Demons are not so easy to deal with.

Although there are many extraterritorial demons at the lowest level, many of them don't even have complete wisdom, and they only have tyranny and murderous desires in their hearts. But among the powerful races of each of the extraterritorial demons, their intelligence is no weaker than that of humans, and there are not many of them.

In the millions of years of warfare with extraterritorial demons, the immortal cultivation world has formed a set of effective methods to fight against extraterritorial demons, but in the past million years, the extraterritorial demons have not become familiar with the fighting methods of the immortal cultivation world?

For a long time, in the battle with the immortal cultivation world, in addition to their own abilities, extraterritorial demons rarely use formations, magic weapons, and other means. If it was millions of years ago, it could still be explained by extraterritorial demons, but in these millions of years, didn't extraterritorial demons really learn anything from the immortal cultivation world?

The alliance between the Immortal Cultivation Realm and the Heavens and Ten Thousand Realms is still being formed, and it will take a while to hone if you want to truly fight against the extraterritorial demons. Chu Huaigu was originally worried that the extraterritorial demons might attack first, but now it seems that his worries are right.

"Now that we've come to this point, it's just a matter of fighting!"

Thinking of this, Chu Huaigu's eyes bloomed with a hint of battle intent, and at the same time, he used his divine sense to contact Yueji and the others, telling them the current situation of the extraterritorial battlefield in the Immortal Cultivation Realm, and asking them to be ready to go to Zuozhen at any time.

Li Wenyuan and the three of them, who were cleaning up the evil magic gate in the immortal cultivation realm, also received an urgent message from the extraterritorial battlefield, not only the three of them, but also the Yuan God True Immortals who were looking for opportunities in other heavenly worlds, and they also received a recall order from the Demon Slayer City.

"The extraterritorial battlefield is in an emergency, the extraterritorial demons are in earnest, many Taoist friends in the extraterritorial battlefield are not there at this moment, it seems that the three of us are going to rush back to the extraterritorial battlefield first!" Liu Siyuan looked at this information, frowned and said to Li Wenyuan and Tianyin.

Li Wenyuan also frowned, they were following a line to investigate, they had already found a lot of people who practiced evil magic, the tense situation in the immortal cultivation world had just become a little relaxed, if they left at this moment, then the work they had done before was likely to be wasted.

"There is no way to do this, I can only explain to the major sects in the Immortal Cultivation Realm, and let them check the people who practice the evil magic sect in their respective spheres of influence, the three of us must rush back to the extraterritorial battlefield as soon as possible, you must know that after receiving this recall order, no matter what you are doing, you must also rush back to the extraterritorial battlefield as soon as possible." Liu Siyuan also sighed and said.

Things suddenly took such a turn of events, which caught Li Wenyuan and the three of them off guard. But there is no way, at this time, it is obviously more important to fight against extraterritorial evil demons, so everyone can only order the major sects in the immortal cultivation world in the name of the extraterritorial battlefield, and completely purge the people who practice evil magic in their own sphere of influence.

After arranging these, Li Wenyuan and the three of them rushed to the extraterritorial void and headed towards the extraterritorial battlefield.

When the three of them rushed to the extraterritorial battlefield, the general of the Demon Slayer City who was in charge of the commander arranged the three of them to the extraterritorial battlefield in the east.

As soon as Li Wenyuan arrived at the front line of the battlefield, he saw that the battle was raging, and the outer magic array laid by the Immortal Cultivation Realm on the extraterritorial battlefield had been beaten a little crumbling at this moment, and the light was constantly flickering, as if it would be broken at any time.

Regardless of the immortal cultivators and Yuan Shen True Immortals in charge of the formation, they had done their best, but in the face of the seemingly endless attacks of the extraterritorial demons, it was still very difficult to resist, and it was not far from the time when the formation was broken.

Li Wenyuan could see clearly that the extraterritorial demons on the opposite side were too organized, constantly using various long-range attack spells to consume the power of the peripheral magic array, and when the previous batch of extraterritorial evil magic power was exhausted, he immediately replaced the next batch of extraterritorial demons and continued to attack the formation.

From the beginning of the battle to the present, it has been a long time, but the results achieved by the Immortal Cultivation Realm are very limited, and the extraterritorial demons killed are very few.

"Is this going to be consumed remotely, and then hand-to-hand?" Looking at the extraterritorial demons who had become well-organized, Li Wenyuan thought to himself in his heart.

If in the two years before he was on the extraterritorial battlefield, the extraterritorial demons were also so well-organized, then I am afraid that he would have been more than lucky.

Li Wenyuan stood quietly on the side and watched, and Liu Siyuan and Tianyin, who came with him, also stood silently aside, and everyone was waiting for the moment when the peripheral formation was broken.

The attacks of the extraterritorial demons were still uninterrupted, and the flickering light of the barrier of the outer formation was already very faint, and it was about to be breached. On the side of the Immortal Cultivation Realm, while the formation was still operating, countless Void Warships came to the front line from the rear, and all kinds of large-scale strategic magic weapons were brought to the front line, as well as a steady stream of combat materials, which were being delivered.

Finally, after the barrier of the outer formation flickered again, it was finally completely broken, and countless extraterritorial demons rushed towards the direction of the Immortal Cultivation Realm like a black tide.

"Whew!"

Li Wenyuan took a deep breath, the brutal battle was about to begin!
