In Lin Tianchen's mind, starlight poured in, like a tangled ball of thread.

This is the composition of the formation, as long as he can reassemble it, he can control the immortal array.

"Haha, then I'll try!"

As a formation mage, he still knows a little.

However, what was in front of him now was the Immortal Array, which was many times more advanced than the formation he had encountered before.

"There are too many stars, you have to take it step by step!"

"First connect points and points to form lines, then form faces, and finally form volumes!"

"The line surface body forms a one-dimensional, two-dimensional and three-dimensional space, so it can be completed quickly!"

Lin Tianchen smiled and began to splice with his familiar knowledge.

His consciousness condensed into form, and his hands began to move.

First, the countless starlight rays were sorted according to the immortal array, and the "line" was formed by countless points.

Then there are countless lines to form the "surface", and finally the countless faces to form the "body".

Lin Tianchen completed the splicing of the immortal array very logically in this order.

"Hum-"

In the end, when the miniature version of the Immortal Array was completely complete, the Tianshu Immortal Array emitted a fluctuation.

Lin Tianchen smiled, his fingertips flashed, and he instantly collected the immortal array.

"That's it!"

The space formation was collected, and he and Xiao Mei'er appeared in the main hall.

Lin Tianchen saw that Xiao Mei'er hadn't refined the phoenix true fire yet, so he didn't bother her.

Sitting on the other side, he began to cultivate in earnest.

On the remote side of the Northern Regions.

There is a huge city with millions of people living in it.

There are martial artists who have cultivated to be strong, and there are many ordinary people.

The city is very lively, with various stalls on the streets, and stall owners greet people warmly.

After a large number of warriors entered the city, they were very conscious and did not cause trouble.

Because there is a city lord's mansion here, which is responsible for the security of the city.

"Bang!

Suddenly there was a sound of shaking underground, and the rocks on the ground began to crack, as if something was about to come out.

Everyone sensed that something was wrong and immediately stepped back.

The guards from the City Lord's Mansion arrived, just to ask what the situation was.

"Boom!"

The ground shook violently, followed by a loud bang, and a deep crater exploded in the ground.

"What's going on? What is this?"

"I don't know! I can't see anything in the darkness down here!"

The crowd stood around the pit, their eyes constantly looking down.

"Roar!"

A tyrannical roar came from inside the pit, and everyone's faces were shocked.

Without waiting for everyone's next move, a behemoth appeared in front of them.

It was a black python tens of meters high, with a turquoise glow in its eyes.

The scales of the body are black, and when the sun shines, it emits an eerie glow.

"Ahh

A woman's pupils dilated, and she opened her mouth to scream.

"Roar!"

The python swooped down in an instant, opened its mouth and swallowed the woman into its stomach.

"Crunch!"

Biting the flesh in his mouth, he stared at everyone fiercely.

"Phew!"

Many warriors were so frightened that they immediately fled in all directions.

"Run!"

However, not long after escaping, large pits appeared in many places on the ground, and all kinds of demon beasts appeared.

"Hehe, it's been a long time since I've opened meat, let's start with this city!"

On the head of a dragon, there sat a man in a black robe, with strange and handsome facial features, with a kind of evil nature.

The thin lips were pale, and the face was pale, as if it was wounded.

"Kids, let's open meat!"

He waved his hand and smiled.

"Roar!"

Suddenly, thousands of demon beasts roared in unison and rushed towards the crowd.

There was a terrible scene in the city, and some warriors tried their best to resist, but to no avail.

"Stop!"

At this time, the lord of the city came.

"Who the hell are you?"

His face was furious, and he shouted.

"It's been a long time since anyone asked me, and for so many years, I've forgotten my name!"

"Let me think about it and see if I can remember!"

The handsome man rubbed his temples and said softly.

His expression frowned slightly, as if he was thinking.

"Ahh

The handsome man's eyes lit up, and he pursed his lips and smiled: "My name is Luo Houjun!"

The city lord frowned, he had never heard of this man's name in his memory.

"Hmph, I don't care who you are, leave me immediately!"

With a wave of the war spear in his hand, the domineering aura burst out, and the Heavenly Star Realm cultivation was released.

"Hehe, just a Heavenly Star Realm cultivator, you deserve to let me leave!"

Luo Houjun felt amused and said disdainfully.

"Hmph, then you're looking for death!"

As soon as the body moved, it burst into an instant, and the war spear danced, and a shot pierced through.

A shot burst out, bursting with all its power, and the void shook violently.

"Cut, scum repair!"

Luo Houjun looked at it with contempt, raised his right hand, and stretched out one finger.

"Hum-"

The black light of his fingertips shot out, and the void suddenly distorted.

The next moment, he pierced through the center of the city lord's eyebrows and collapsed to the ground, without any breath.

Luo Houjun looked down, and his domineering voice spread: "I prefer others to call me "Demon Ancestor!"

Hall of Stars

During this period of recruitment, although the situation in the Northern Regions was very chaotic, powerful warriors from all sides did not dare to join at will.

But there will be some people who will come to join in the reward.

Heaven and Earth City have also come to some Heavenly Star Realm cultivators in the past few days, and as for the Xuantian Realm, I am afraid that they have already stood in the camp.

Of course, Lin Tianchen welcomes it, and meets in person to get acquainted with it briefly.

Now the strength of the Star Hall is gradually growing, not only the two masters of Lin Tianchen and Xiao Mei'er, but also some masters of the Feng clan.

Xia Qianjun and the others, because of taking pills, their cultivation was also raised to the level of the Heavenly Star Realm.

In the following time, Lin Tianchen concentrated on cultivation.

A few days later, a piece of news spread throughout the Northern Regions, that is, the most mysterious spiritual source secret realm in the Northern Regions was about to open.

The news reached the Hall of Stars.

Lin Tianchen knew that it would definitely not be simple for such news to come out at this time, and he thought with a solemn face.

"Tianchen!"

"Huh!"

Xiao Mei'er appeared, and now she exudes a strong aura around her.

Lin Tianchen's eyes swept and he said in surprise: "Your cultivation has entered the immortal realm?"

His immortal sense swept and found that Xiao Mei'er's cultivation had skyrocketed a lot.

"Well, I've reached the First Rank Immortal Realm!"

Xiao Mei'er nodded with a smile.

"Great!"

Lin Tianchen slapped his hands violently and said with a smile.

Then he told the news of the opening of the Spirit Source Secret Realm.

Xiao Mei'er said with a smile: "Tianchen, you are right, the Lingyuan Secret Realm is opened at this time, which is to completely solve the troubled times in the Northern Regions!"

Lin Tianchen asked, "How can you be so sure?"

As soon as he said it, he reacted, it must have been told to her by the Feng clan.

"Then do you think we should go in?"

Lin Tianchen asked.

"Go!"

Xiao Mei'er nodded affirmatively, and then began to explain.

"There are a lot of supreme treasures in this spiritual source secret realm, and there are a lot of good things to improve cultivation! I don't think anyone can resist such a temptation!"

"Whether it's a disciple of the Spirit Academy or a demon cultivator, they will all pass, and this time it is estimated that it will be the time to determine the winner and loser!"

Xiao Meier said solemnly.

Her eyes looked at Lin Tianchen and said, "You have the token of the Immortal Spirit Academy, even if you don't want to go in, I'm afraid I will pull you in when the time comes!"

Lin Tianchen was stunned for a moment, and said helplessly: "Isn't it?

"Of course, the Spirit Source Secret Realm was created by the five major courtyards together, what do you think is opening it now, of course, it is the final decisive battle!"

"This secret realm is both a treasure and a dangerous place!"

Xiao Mei'er said with a solemn expression.

Lin Tianchen nodded, he understood that the manipulators behind the scenes had begun to act.

In order to stabilize the situation in the Northern Regions, get all these powerful people into it.

Of course no one will not go in, because of the temptation of treasure.

If you don't go in, your enemies will get treasures and increase their strength after entering, and you will be the ones who will die when the time comes.

In other words, both sides have concerns that nothing can make the other stronger first.

Lin Tianchen understood that he couldn't run this battle, whether it was because of the token, or the Blood Refining King, or even to improve his strength, he had to go in.

After the two discussed, they decided to bring only a few masters of the Feng clan over, and the rest of them guarded the Star Palace.

He didn't want to go and his backyard catch fire.

Without the strength of the Immortal Realm, to enter is to find death.

What's more, the current Star Hall is basically a martial artist who has cultivated in the Heavenly Star Realm, which is too weak.

Xiao Mei'er only brought a few people, and let the remaining masters assist Xia Qianjun and others to manage the Star Palace.

After the arrangements were made, Lin Tianchen and the others set off.

The Spiritual Source Secret Realm is probably in the center of the Northern Regions.

However, because of the long-term closure, no one knows the exact location at all.

It will only be discovered when it appears on its own.

This time, the secret realm appeared at the top of the Heavenly Dome Mountain Range.

The Sky Dome Mountain Range is in a very peculiar location, it is surrounded by lakes on all sides.

Viewed from afar, the mountains look like they've grown out of a lake.

When Lin Tianchen and the others arrived on the flying demon beast, some people had already arrived on the top of the mountain.

"It's the Wind Spirit Courtyard and the Phoenix Spirit Courtyard!"

Xiao Mei'er swept her eyes and recognized it.

Lin Tianchen's eyes looked over, he had seen the disciples of the Phoenix Spirit Academy.

However, it was the first time I had seen the clothes they were wearing.

"This should be the uniform of the Phoenix Spirit Academy!"

Lin Tianchen said secretly.

The chest of the disciple of the Phoenix Spirit Academy is embroidered with a phoenix that has been burning flames, which is very realistic, just like a living one.

Behind several disciples, there were a large number of martial artists, among whom the Lingxiao Sword Sect was also inside.

His gaze turned to the Wind Spirit Temple, this was the first time he had met.

Wearing a blue silk brocade robe, with a small golden sword embroidered on the clothes, faintly exuding an aura.

"It should be a spiritual courtyard that is good at using swords!"

He said secretly.

"Roar!"

The demon beast raised its head and screamed, and landed steadily.

Lin Tianchen and the others jumped down.

"Hehe, I didn't expect the person who came to be the Lord of the Lin Palace, I really didn't expect it!"

Mu Clutch said with a smile.

"It's fine!"

Lin Tianchen smiled and nodded.

His eyes swept over the disciples of the two Great Spirit Courtyards, and then he stopped caring and waited quietly.

"If you want to enter the secret realm, you must have a key to activate, and the key is in the hands of the five courtyards!"

Xiao Mei'er approached Lin Tianchen and said softly.

Lin Tianchen nodded, it turned out to be like this, no wonder they didn't go in.

Just wait!

A few minutes later, both the Thunder Spirit Temple and the Xuan Ling Temple came.

Lin Tianchen didn't know anyone, he stood there silently, looking curiously.

"Haha, it's all early!"

At this time, a rampant laughter came, and everyone's expressions changed dramatically.

Lin Tianchen's face turned cold and he looked up.

In the distance, a huge four-winged beast flew in, its wings stretched dozens of meters long.

The speed was very fast, and as it approached the top of the mountain, a terrifying force descended.

The wings fanned, like a violent wind and waves, and a whirlwind suddenly blew like sand and rocks on the top of the mountain.

"Hmph, Blood Refining King, you're quite rampant!"

Mu clutch shouted unhappily on his face.

"Haha, what if you have the strength to be rampant, what can you do to me!"

The Blood Refining King was full of momentum, and his speech was extremely domineering.

"You..."

Mu was unhappy and was about to continue, but when he saw a large number of people and horses behind the Blood Refining King, he swallowed it.

The people he brought with him were not ordinary people, and those who could come over must at least condense into immortal bodies and demon bodies, otherwise after entering, it is estimated that they will be killed in an instant.

The Blood Refining King's eyes were disdainful, and suddenly the corners of his eyes twitched.

"Huh, Lin Tianchen, Xiao Mei'er, you are also here, what a coincidence!"

The Blood Refining King said, grinning, his eyes flashing fiercely.
