According to the memories of the Iron Corpse Master, that small secret realm was located more than 300 meters under the sea, and it was accidentally discovered during patrols.

Later, it took a lot of effort to break through the guardian formation.

It's a pity that there is nothing in it except the corpses that are shocked by the road.

Originally, I thought that Lu Jingkong had searched all the treasures, but unfortunately I didn't find anything valuable on Lu Jingkong after looking for a long time.

The corpse was then taken away by the Iron Corpse Master, leaving only one Pillar Elder to guard the space.

According to the perception of the Iron Corpse Master, the concentration of aura in that small secret realm had reached the level of a medium-sized spiritual vein, and it was definitely a treasure land for cultivation.

It was only because he was worried that something would go wrong in the secret realm that the Iron Corpse Master did not cultivate in it, and wanted to live for a few years and see the situation before making a decision.

A small secret realm comparable to a medium-sized spiritual vein is much stronger than Kuroshio Island, and it can definitely make Xu Mu's cultivation speed increase a lot faster.

Don't worry about the aura of the tool corpse anymore!

Xu Mu thought carefully about the feasibility of the matter, and after feeling that there was no big problem, the coffin with the tool corpse on his back set off.

According to memory, it didn't take much effort to find the sea area where the secret realm was located.

After determining the position, Xu Mu took a deep breath, pinched the magic trick in his hand, and his body began to change, his arms gradually turned into shark fins, and a row of sharp shark fins grew on his back.

However, his face still retains the appearance of a human, but his eyes have become sharper and have a fierce aura.

He plunged headlong into the sea water and dived into the trench at a depth of 100 meters at the bottom of the sea, and it was dark in front of him, but Xu Mu could clearly see everything around him.

It is surrounded by huge coral reefs and a variety of marine life, one of which is a large red-spotted starfish with long tentacles that feeds everywhere.

Compared to the starfish that were not aggressive in their previous lives, the attack power of these red-spotted starfish is quite powerful, and in an environment like the bottom of the sea, even in the late stage of qi training, it will be very difficult to deal with.

And they will also spit out a paralyzing toxin, infiltrating into the spiritual power, if you don't pay attention, you may be hit during the foundation building period.

When it was first discovered, it made the people of the Iron Corpse Gang useless.

Sensing Xu Mu's arrival at this time, these red-spotted starfish, which were bigger than people, immediately rushed up, but they did not come up to attack, but expressed their submission to Xu Mu, showing their vital points one by one, showing their closeness.

Xu Mu's current cultivation has reached the late stage of foundation building, and the Twelve Shocking Techniques have also reached the consummation level, and after transforming into the Silver Shark form, his power is several times higher than the original, and the ordinary sea clan only has to surrender when they see him.

Of course, not all sea tribes have this ability of his, only the royal family of the sea tribe can make ordinary sea creatures submit, which is one of the main reasons why they are called royalty.

Ignoring these courtesy starfish, Xu Mu walked through the coral group, and according to the memory of the Iron Corpse Master, he found a trench in it that was no more than ten meters long and two meters wide.

This is the entrance to the small secret realm, and it was a complete accident to find out at the beginning.

There were no guards at the entrance, and Xu Mu used his divine thoughts to strafe, but he just set up a phantom array to avoid being detected.

He began to pinch the spell in his hand, and an illusion formation and a defensive formation gradually appeared in front of him. In the illusion formation, the sea water began to become clear and bright, as if in a crystal palace, and the defensive formation was a thick energy barrier that could withstand attacks from the outside world.

Xu Mu entered the small space created by the illusion formation, which was a spacious and quiet underwater cave. There were all kinds of strange creatures in the cave, but none of them posed any threat to Xu Mu.

After passing through the phantom array, Xu Mu's fingers moved slightly, and a faint spiritual power slowly flowed out from the tips of his fingers, forming a tiny rune.

His fingers continued to dance, and the runes gradually expanded, becoming more and more obvious. Xu Mu's brows furrowed slightly, his finger movements became more proficient, and the runes became more complex.

In the end, the runes hit the defensive formation, and the formation light curtain began to fluctuate violently, Xu Mu's fingers stopped, he took a deep breath, and then said softly: "Defensive formation, open!" ”

As his words fell, the runes began to glow, and a powerful energy spread around the runes, forming a stable channel.

The passage of this defensive formation could only last for a while, and Xu Mu quickly stepped over without hesitation.

With the crossing formation, the scene in front of him suddenly changed, and when he raised his eyes, Xu Mu's pupils couldn't help but shrink slightly.

The space in front of him was about less than ten miles in circumference, a hundred feet high, and completely supported by huge bones.

The skeleton emitted a white glow that illuminated the entire space.

Standing at the entrance, Xu Mu suddenly felt incomparably small.

"What kind of monster bones are these?"

Such a huge skeleton, Xu Mu had never seen it.

"Could it be the legendary True Spirit Behemoth?"

Xu Mu's heart was shocked.

The True Spirit Giant Beast is an existence comparable to the Mahayana of human beings, almost standing at the apex of the mortal realm, and no one can subdue it unless the immortals make a move.

"No, if it's really a true spirit beast, it's impossible for the Iron Corpse Master to abandon it!"

Xu Mu approached a place to check, and with a little force on it, he pinched the bones into pieces.

“……”

It doesn't look like it's the bones of a true spirit, but of course, it's possible that they've been around for too long.

Xu Mu, who had some regrets in his heart, released his thoughts to feel everything around him.

The space is filled with a rich aura, and many strange-shaped creatures are either flying in the air, lurking in the water, or crawling on bones, bringing a vibrant atmosphere to this small space.

The only thing that is the same is that they are all very weak.

Although the place is small, it has a strong aura, and it stands to reason that there should be a powerful demon beast born.

"It is estimated that they were all killed by Lu Jingkong!"

Xu Mu didn't dwell too much on this issue.

With the unscrupulous strafing of Shen Nian, the elders of the Iron Corpse Gang who stayed in this space also discovered his existence.

"Who are you?"

A black light flew from a distance and landed in front of Xu Mu, revealing the figure of an old man in a black robe.

The old man was thin and his skin was pale, as if there was no trace of blood. His eyes were sunken in their sockets, and there was a cold aura in his black pupils, which made people shudder.

He was wearing a black robe, covered with all kinds of strange symbols and spells, which looked very mysterious, and held a black bone staff in his hand, the head of which was inlaid with a blood-red gem, which emitted an eerie light.

"You, you're—"

When he saw Xu Mu's figure clearly, the old man, who was originally quite calm, was not calm in an instant.

Because this image is all too familiar to him.

It was the same Silver Shark who attacked the Iron Corpses a year ago.

Although he hadn't seen Xu Mu in person, he had seen many of his portraits and photos, so he recognized him at a glance.

Two blue-faced fangs, wearing armor, and blood-red eyes were immediately released by him.

"Looks like you know me, so that's easy."

Xu Mu's mouth raised slightly, and the silver phantom thunder rolled in his hand, making a piercing buzzing sound. His eyes were sharp, his body was agile, and he approached the old man step by step.

The old man's face turned pale, and he quickly took out a porcelain bottle, which contained a black liquid. There was an eerie aura in his eyes that made people shudder.

Xu Mu's eyes flashed, and he suddenly attacked, and the silver phantom thunder instantly turned into a silver snake and pounced towards the old man. The old man hurriedly raised his hand, and a black air stream erupted from his hand, engulfing all the silver phantom thunder.

At the same time, the two refining corpses were divided into left and right, and quickly rushed towards Xu Mu.

"It's kind of interesting!"

Xu Mu's expression remained unchanged, as if he hadn't seen the vicious refining corpse at all.

The old man's eyes flickered, and he suddenly threw out the porcelain bottle in his hand, and the black liquid inside turned into an evil dragon, which was fishy and smelly, covering Xu Mu directly.

"Huh?"

Just when the old man was puzzled that Xu Mu was hit so easily, a silver lightning bolt suddenly appeared out of thin air and hit the old man's chest directly.

The old man let out an exclamation, and his body jerked back a few steps, but quickly stood up again.

"Is there any?"

Xu Mu's figure appeared, and a hint of surprise appeared on his face.

I didn't expect that the other party actually had two magic weapons on his body that could resist the attack of phantom thunder, and it seemed that these people really took great pains to deal with him.

If that's all there is to it, it's a break.

Xu Mu didn't wait for the old man to react, and launched another attack, his body moving as fast as lightning, releasing silver thunder while dodging the corpse refining attack.

Silver phantom thunder continued to shoot out from his hands.

The old man didn't hold on for more than two strokes, and he was hit on the head and froze in place.

As the old man fell into a hallucination, the two refining corpses lost control and stopped.

Xu Mu didn't mean to kill the other party, and after stripping the old man of all he could, he pulled him out of his illusion.

"Go back and tell you the Iron Corpse Gang, this will be my territory in the future, if you dare to disturb me, I will destroy your Iron Corpse Gang!"

After speaking, Xu Mu revealed his cultivation in the later stage of foundation building.

As long as the other party is not stupid, they will not fight for territory with a sea clan in the late stage of foundation building at the bottom of the sea.

Not to mention that the Iron Corpse Gang only has a foundation building period, even if it is the Jindan period, I am afraid that they have to think twice, and it is because of this that Xu Mu dares to occupy this place so generously.

The elder fled in the desert, and it was estimated that he would leave a shadow for the rest of his life.

Xu Mu carefully probed, modified the defensive formation and the phantom formation, and then arranged several layers of formations separately to block the entrance of the cave, and only after making sure that there was no danger did he take out the tool corpse.

"With such a strong aura of heaven and earth, the effect should be very good!"

At this time, Xu Mu's eyes inevitably revealed a frenzy, he took a deep breath, then entered his body, closed his eyes, and operated the secret technique of yin and yang.

With the operation of the secret technique, the tool corpse was immediately activated, and the surrounding heaven and earth aura began to pour into her body frantically, and the huge heaven and earth aura made the tool corpse begin to tremble, and it seemed to be a little uncomfortable.

But she didn't stop, and as time went by, she absorbed the aura of heaven and earth even more frantically.

It didn't take long for him to fully get used to the concentration of aura here.

Then, driven by the secret technique, it was injected into Xu Mu's body without reservation.

His cultivation began to continue to improve, his spiritual power became stronger and stronger, and his perception became more and more keen.

The surrounding scenery also began to change, a picture of yin and yang alternating appeared in the sky, strange flowers and plants appeared on the ground, and Xu Mu's cultivation power had already affected the entire space.

Time passed minute by minute, I don't know how long it took, Xu Mu's body suddenly let out a buzzing sound, and his breath soared, he stopped the operation of the secret technique, and slowly opened his eyes.

"Build the ninth floor! I didn't expect it to be so easy to reach! ”

Ordinary people may have to cultivate for more than ten or twenty years, but he broke through in just a few months, and the surprise in his heart can be imagined.

Next is the advanced Jindan!

It was much, much faster than he expected.

Just when Xu Mu was thinking about whether to continue cultivating for a period of time to consolidate his cultivation or leave, an extremely angry voice sounded in Xu Mu's heart.

"Ant-like stuff! How dare you defile my body! ”
