Old Ancestor Liu Fan sensed that there was a palpitating breath revived, and he glanced at the vast Immortal Realm, but the earth was vast, and that breath quickly disappeared.

"The Immortal Realm, it's not easy!"

Liu Fan sighed, his eyes narrowed slightly, he retracted his gaze, stepped out, and disappeared in place.

.........

The frontier of the Immortal Realm is not the end of the Immortal Realm, but the boundary of the Immortal Realm territory that was opened up by the human ancestors and is suitable for habitation and cultivation.

The Immortal Realm is ancient and vast, and I don't know how many terrifying creatures have been bred.

It is vast and endless, most of it is poisonous gas swamps, wild, primitive and barren land, and the immortal qi is disordered and highly poisonous, which is not suitable for cultivation.

Only the eastern region was exploited by the ancestors of mankind.

Because the eastern region is relatively gentle, there are few sinister and fierce places, and the temperature of immortality is mild, which is suitable for cultivation.

This area is not even a quarter of the Immortal Realm, but the area is unimaginably large, a hundred times that of the Taivoid Realm.

On one side is the chaotic islands of the open sea, and on the other side is a wild and barren land.

And the border with the wild and barren land is called the frontier.

The frontier is cast with hundreds of millions of miles of Great Wall, like a giant dragon lying across the immortal realm, with no end in sight.

This Great Wall is known as the Life Fortress of the Frontier Fortress.

"Change the guard, watch out for vigilance!"

On the Great Wall, there are armored figures walking, shouts and trumpets are heard in all directions.

Liu Sanmao.

Climbed the battlements of the Great Wall with the clansmen, hurriedly put on armor and stood up, scanning the surroundings with bright eyes, and being on guard.

Beside him, Liu Youfu was also checking the bow and crossbow, checking the prohibitions, and replenishing the divine power of the formation.

"Sanmao, is there any movement outside?!Did you see the thief willow?"

Liu Youfu asked, wiping the bow and crossbow, the crossbow arrow that flashed with the power of the law could shoot the planet.

Liu Sanmao shook his head, "I didn't see it, it was foggy outside, and I couldn't see anything clearly." ”

Liu Youfu walked over and looked up.

Sure enough, outside the Great Wall of the frontier, the white fog was surging and boundless, and those towering and tall sacred mountains were also hidden, and there was silence all around.

The one hundred and eight divine hair clones sent to the Immortal Realm by the old ancestor were besieged by major forces, hid in Tibet, and finally, came to the frontier fortress.

It is also a military powerhouse, and it is also the fortress of the Immortal Realm, so it has arranged terrible prohibitions and formations that connect the sky and the earth, and is guarded by the ancient Divine Kingdom of Great Xia.

The Temple and the Temple of Immortality have also sent paladins and immortals to help protect and block dangerous things in the wild lands beyond the frontier.

The Great Xia Divine Kingdom, or the Divine Temple, and the Hall of Eternal Life, are all the three oldest forces in the Immortal Realm.

They have existed longer than any ancient family, and their power is even more intertwined, incomparably large, and their status is transcendent and admired by all spirits.

They established twelve Great Xia Academies, twelve Temple Academies, and twelve Immortal Academies, and mastered countless ancient cultivation methods and supernatural powers, as well as ancient divine skills that had been lost in the outside world.

A total of thirty-six colleges!

The Ancient Families, the Ancient Cultivation Sects, and other cultivation forces or casual cultivators were all proud to be able to join these thirty-six academies.

As long as you join these thirty-six academies, your status will be turned upside down, and after serving on the Great Wall of the Frontier for 30,000 years when you graduate, you can regain your freedom, either return to the major families or your previous sects as high-level leaders, and return to your hometown, or stay in the academy and serve as a mentor, or be favored by the three transcendent forces, and be promoted to knight or other positions.

However, the frontier fortress is very dangerous, there are often casualties, and the students of the Thirty-six Academy do not dare to be careless, but they are often extremely talented, even if they intern and serve here, they will recruit scattered cultivators or families from the Immortal Realm to come and protect them together.

Therefore, as long as the monks who volunteer to serve here will enjoy certain benefits.

Being hunted down by the enemy and being sheltered is only one of the benefits.

At the same time, it is also allowed to open up the battlefield and conduct large-scale wars here, firstly, to avoid casualties among the innocent cultivators in the border fortress, and secondly, in the frontier fortress war, the gathered evil qi is the best nourishment for the border fortress array, which can strengthen the formation.

The one hundred and eight doppelgangers of the old ancestor, after several turns, were chased and killed by the ancient family Liu family, so they fled here and volunteered to join the fortress Sanlitun, which gave him a chance to breathe, multiplied, and survived.

Then, it continued to grow and develop, established Liucheng in Sanlitun Biansai, and after gaining a firm foothold, it declared war on the ancient family Liujia, and the two sides fought a decisive battle on the battlefield of Biansai for tens of thousands of years.

There is a five-fold time difference between the time of the Immortal Realm and the Tai Void Realm, and the Tai Void Realm seems to have passed thousands of years, but tens of thousands of years have passed in the Immortal Realm.

And Liucheng, which was established by the ancestor clone in Sanlitun, is also becoming more and more famous, especially after this war, the Liu family is even more famous.

Of course, the Immortal Realm Frontier Fortress is so vast and deep that Sanlitun is only the size of a thumb of the Great Wall of the Hundreds of Millions of Miles.

Therefore, this war of the Liu family is only an insignificant local war.

It won't attract the attention of the bigwigs guarding the frontier fortress at all.

And the evil spirit brought by the war strengthened the border formation, and even more satisfied the talented students serving in the frontier, and secretly encouraged the war.

"Sanmao, I heard from the clansmen that the Taishang Ancestor has descended to the Immortal Realm and is rushing over, I don't know if it's true?"

Liu Sanmao blinked and said: "I have also heard about this, the ancestral land of our Liu family, I heard that it is not in Sanlitun, where we are responsible for guarding, but in a small place in the Nether, that is the base camp of our Liu family!"

"I'm looking forward to it, I hope the Taishang Ancestor will come over early and take us out of here!"

"We've been here for more than 10,000 years, and we've been here since my grandfather's generation, we're ......"

As the two were talking, a bird song suddenly came from the sky, and then a majestic voice was heard on the edge of Sanlitun......

"Senior Tao patrols, where is the head of the Liu family?!"

Senior Tao is a student of the ninth school among the thirteen schools in the Great Xia Divine Kingdom, and he is about to graduate, so he came to Biansai for internship and service.

And Sanlitun happens to be one of the border areas he is responsible for guarding.

The one hundred and eight doppelgangers of the old ancestor worshiped his pier and were assigned to Sanlitun to guard the fortress here.

"Whew~"

In the void, the lightning eagle flew down, and there was a Taoist figure standing on it, and a young man in front of the middle was Senior Tao.

His breath was deep, he was a half-step immortal, his eyes were majestic, he scanned the defenses, formations and prohibitions of Sanlitun, and found that everything was in order, and a look of satisfaction flashed in his eyes.

But he seemed to suddenly remember something, and his face was full of confusion.

This time, he came to mediate the war between the two Liu families, and at the same time, at the behest of a big man in the Great Xia Divine Kingdom Academy, he hired the Taishang Ancestor of the Liu Family to serve as a tutor in the Great Xia Divine Kingdom.

Although it is a very unpopular physical cultivation teacher, it is also a teacher!

Looking at Liucheng near Sanlitun, Senior Tao sighed for a while and looked emotional.

Once upon a time, he would never look at such a family.

In the Immortal Realm, there are too many such family or sect forces.

However, who would have thought that this family would have a very fierce Supreme Ancestor, who came across the border, broke the chaos boundary wall in one fell swoop, and made several immortal heavens flee in the wilderness.

"Such a master, at first glance, is he short-tempered, does not do background checks, and directly recruits into the academy of the Great Xia Divine Kingdom as a physical cultivation instructor, is it appropriate?!"

"Moreover, I'm just a student who is about to graduate, and I go to recruit a big guy who has run away from the wilderness, how will people look at me?!"

"Bah, those old guys in the academy, eighty percent want to see me laugh, right?!"
