A lake stretching for tens of kilometers from east to west, with a small island in the center.

The vegetation on the island is lush.

The aura is three points richer than that of other places.

In the lake surrounding the island, you can vaguely see several behemoths wandering in it, and the momentum that leaks out at will makes the demon beasts within a radius of ten miles on the shore lie on the ground.

At this time.

Above the slightly gloomy sky, a long-standing ordinary demon beast flying bird flew down from the clouds, and Lin Xuan, who was standing on top of this flying bird, saw the island in the middle of the lake below, so he used the Great Void Technique, hid in the void, and fell towards the island below.

Swish!

Meanwhile.

Beneath the gloomy lake, a dark and swift afterimage pierced the void in an instant, and made a piercing sound, piercing the demon beast bird, causing it to fall into the lake and disappear.

Lin Xuan after stepping on the island in the middle of the lake.

So he went straight to the island, the dark stone cave.

A black hole has carved out of a smooth cliff, like a giant beast with a wide open mouth, waiting for its prey to come to the door.

"Huh!"

Lin Xuan flew from the gap between time and space, and the wings of creation behind him suddenly flapped, taking advantage of a strong wind to enter the stone cave.

It's about a hundred feet away.

The way was blocked by a huge gate covered with rust, and the iron gate was full of patina, and a quaint atmosphere came to the face.

The doors are closed!

Lin Xuan stepped forward.

When he reached half a meter of the iron gate, he stretched out his right hand and stroked the delicate totem patterns on the iron gate.

It is extremely cool to start with, not like ice eating bones.

"Open it for me!"

Lin Xuan wanted to try it and see if he could blast it away with brute force.

A million catties of huge force burst out from his right arm, and his right arm swelled in a circle, and pressed the iron door of the treasure house.

Rumble!

There was a muffled thunder that shook and reverberated throughout the empty cave, and at the same time, a little rubble fell from both sides of the iron gate.

After a palm, the iron door did not move.

"It seems that there is a special door god guarding it!"

Lin Xuan saw that he couldn't blast away with brute force, but there was no trace of panic in his eyes, he was all indifferent.

Then.

Lin Xuan took out the fragment of the map, and with the memory of the previous large number, he played several complicated ancient magic tricks with both hands.

At the same time, Lin Xuan's lips moved slightly, and a mysterious note flew out.

It's the same spiritualism he imitates!

This spell didn't need to rely on other things, but because Lin Xuan hadn't extracted the complete spell, he could only rely on his memory to perfect it as much as possible.

Airplanes!

As soon as the void trembled, a bald man with a glowing body flew out of the void.

Lin Xuan glanced at it and used the probing function.

Nickname: Treasury Door God

Race: Machine Spirit

Level: Refining the Nine Heavens

Primary Ability: None

"Sure enough, it's the door god!"

Lin Xuan's eyes were happy.

Due to the control of the Soul Restraint Technique, the door god of this treasure house could only be subject to Lin Xuan for the time being.

However, because the spirit technique is imitated, the effect does not seem to be enough to last for twenty seconds, and no one dares to guarantee that after this god regains consciousness, he will not be angry with Lin Xuan because he is controlled.

Lin Xuan directly ordered him to use his authority to open the door of the treasure vault.

And at this time.

Lin Xuan also seemed to feel the restlessness of the outside world, as if there was a violent beast running wildly on the island, causing the entire island to be affected, and trembling slightly.

Outside.

The demon beast guarding the island, after hearing the sound of the thunderous explosion, knew that someone had quietly touched the island.

directly turned into a half-demon form, staring at the black-armored strong man with the crocodile head, and the dark green vertical pupils were tyrannical.

The thick and powerful lower limbs, every step on the island, can be deep on the stiff rock, stepping on a shocking small pit, the momentum is extremely amazing.

Almost instantly, the crocodile demon crossed a distance of hundreds of feet, like a steel monster loaded with cargo and equipped with rocket jets, and rushed into the black hole leading to the portal to the treasure house.

"Found it!"

When this crocodile demon was a hundred meters away from the bronze iron gate, in his line of sight, he could see Lin Xuan who was about to enter the portal.

The crocodile demon's pupils shrank, and a hint of surprise appeared in his eyes.

As the guardian demon beast of the treasure house of the Northern Emperor of the Great Underworld, he naturally knew that entering the treasure house required a completed treasure house map, with the power of crossing the tribulation realm, and attracting the power of the treasure map to make the door god open the door.

But now, the scene that happened in front of him was completely unexpected.

He didn't feel the aura of the treasure map at all just now.

Rumble!

This crocodile demon who couldn't stop Lin Xuan could only raise his fist angrily and slam it on the bronze giant door.

And the door god on one side finally regained his senses, and he was a little stunned about what he had done just now, and after he eased up, his eyes were more jealous.

At this time.

Enter Lin Xuan at the other end of the door.

As far as the eye can see, there is a dark palace, and it can be seen that the palace of this treasure house is part of the whole.

Although the realm of the Great Emperor of the Northern Darkness is not as good as the tuba that he cultivated to the top at the beginning, his strength is also in the forefront among the Great Emperors of the Middle Ages.

This treasure house inheritance is just one of his many inheritances.

Lin Xuan looked up.

A scorching wheel of fire, the light emitted lit up the entire palace.

After Lin Xuan stepped into the palace.

After a closer inspection, there was a study where the Northern Emperor lived in this part of the remnant palace.

Push open the door to the study.

As far as the eye can see, there is a table, a bookshelf, pen, ink, paper, and inkstone, but the ink in it has already dried.

Lin Xuan just glanced at it and ignored it.

These pen, ink, paper, inkstones, and books were all treasures to other monks, but to Lin Xuan, who had a full-level Immortal Emperor account, they were just rubbish.

In this treasure house, the only thing he can take a slight fancy to is the supreme inheritance of the Northern Hell Emperor, "Northern Pluto Divine Skill".

This is a special technique to restrain the demons, I think when the treasure house of the Northern Emperor was opened, there were many demon powers who came here to snatch this thing in the Hengduan Mountain Range, and both sides sacrificed a lot of powerful people above the Dao realm.

It seems that in the final result, the back third of this Northern Pluto Divine Skill was snatched away, and it became a crippled exercise that could only be cultivated to the Refining Void Realm.

The demons are slightly better!

Now that Lin Xuan has crossed over, this time the Northern Spiritual Skill is complete.

Inside the study.

It is the cultivation room used by the Northern Emperor.

In the cultivation room, the layout is simple, with only a futon and a portrait of the Great Emperor of the Northern Underworld.

When Lin Xuan stepped into the cultivation room.

The portrait of the Great Emperor of the Northern Underworld seemed to come to life, and countless mystical runes flew out on it and condensed into a rune scripture.

On the scriptures, four golden characters are written vigorously and powerfully.
