Li Mu stood in the sky above the far north, looking down at the natural array of icebergs below, full of admiration.

The world is truly full of wonders; the amazing creativity of nature is simply like a miracle.

This was the third time Li Mu had encountered a natural formation. He came here because he suspected there was a formation here after watching the video.

Now, the natural formation before his eyes has confirmed his guess.

Each time he discovered a natural formation, he gained an opportunity from it.

The first time, at Guojiao Lake, the strange rocks protruding from the water formed a natural formation, and he had an epiphany and advanced in level next to the formation.

The second time, he encountered a natural formation composed of stone mountains in the Stone Forest, where he cultivated to the point of spiritual energy transformation into liquid.

How will it be this time? He's really looking forward to it.

Upon encountering a natural formation, Li Mu did not rush in. Instead, he landed on an iceberg and entered the Golden Pearl World.

The natural formation cannot be broken; he needs the array flags to ensure his entry.

In the Golden Pearl World, Li Mu took out all his gold and began to continuously refine array flags.

More than two months later, he refined all the gold bars into array flags, a total of more than three hundred.

After refining the array flags, he began absorbing chaotic energy from the opal pile to cultivate martial arts, hoping to break through to the Qi Condensation Realm.

Six months later, his martial arts cultivation finally broke through to the Qi Condensation Realm. With a punch, his inner energy was released, causing dust to rise in the Golden Pearl World.

With each breath, a surge of chaotic energy was rapidly drawn into the body and sank into the dantian.

Currently, he is at the early stage of Qi Condensation Realm, and his martial arts cultivation level is comparable to that of the eighth level of Qi Refining Realm.

The combined strength of cultivating both immortal and martial arts should not pose much of a problem against cultivators below the Foundation Establishment stage.

.

After leaving the Golden Pearl World, Li Mu rested on the iceberg for a day before embarking on his polar expedition.

This natural formation is extremely large, covering an area of ​​more than ten kilometers.

After descending from the iceberg, he slowly entered the natural formation.

Sensing the direction of the spiritual energy flow, they explored along the way, and once they encountered an array that blocked their way, they set up array flags.

This exploration may seem to be moving forward, but it is by no means a straight line, which is precisely the unique magic of formations.

The way of formations is also a way of deception.

Three hours later, Li Mu deployed more than a hundred array flags and finally arrived at the foot of an iceberg.

This iceberg looked no different from the others. Li Mu had come here following the guidance of the array flags.

Moreover, this iceberg also has several smaller icebergs forming a formation, creating a formation within a formation.

Fortunately, he had prepared enough flags, and the iceberg gave him a strange feeling, as if someone was inside it.

Li Mu recalled the path he had taken since entering the formation, and he judged that this was definitely not the center of the formation.

An iceberg that wasn't the center of the formation actually had a series of interconnected formations, which made Li Mu feel that it was very unusual.

Out of curiosity, Li Mu set up array flags again and headed towards another iceberg not far away, only to find that this iceberg was also reinforced by an array.

Although both icebergs are reinforced by arrays, the iceberg next to them appears more ordinary.

The iceberg had spiritual energy converging towards it, and if Li Mu hadn't cultivated immortal techniques, he wouldn't have been able to tell.

He returned to the foot of the iceberg and began to ponder this complex array within an array.

.

After an hour of simulation, Li Mu began to deploy a large number of battle flags around the iceberg.

After dozens of array flags were deployed, a passage leading to the iceberg appeared.

After Li Mu set up two more array flags, a portal appeared on the passage leading to the iceberg.

In front of the gate, there were some broken ice shards, like footprints left by people or animals.

Li Mu walked to the door and hesitated for a moment. He had long felt that there was something strange about this iceberg. Could there really be someone inside?

If there is such a person, then that person should be a cultivator, either a martial arts cultivator or a Taoist cultivator.

With his doubts in mind, Li Mu turned around to look back, and something even stranger happened.

In the field of vision, the entire ice valley was clearly visible, without a trace of any formation.

He even had some doubts that he could have gotten this far without the flags.

Surprised, he began to think about the missing researchers and martial artists from the Zongwu Department. Could it be that they all disappeared after he came here?

This idea is very likely.

So why would these people, who came out to investigate or explore, end up here?

Thinking of this, Li Mu immediately opened his divine sense to its full extent. Currently, the coverage range of his divine sense was only about three thousand meters, but that was enough.

Soon, Li Mu's divine sense detected something different on the mountainside of the iceberg, something that ordinary people could also see with their eyes.

Because there is a blue light emanating from an ice cliff halfway up the mountain. This blue light doesn't shine continuously, but rather several times a day.

This unusual phenomenon is attractive to both scientific researchers and martial artists.

It seems that the missing persons are connected to both the blue light and the portal.

After thinking for a while, Li Mu leaped up the mountain, intending to investigate the strange phenomena halfway up before venturing into the heart of the mountain.

A few minutes later, Li Mu arrived halfway up the mountain and saw the thing that occasionally emitted a blue light, which made him overjoyed.

It turned out to be an extremely pure ice lotus.

These spiritual beings, blending seamlessly into the ice and snow, were truly well hidden; even my divine sense couldn't detect them.

.

The Ice Lotus is a spiritual creature that grows in extremely cold places; even when frozen, its growth cannot be stopped.

It has few branches and leaves, and its flower buds resemble the first buds of a lotus flower, hence its name.

This is the main ingredient for refining the Soul Cleansing Pill, which is a precious elixir used to cleanse and purify the soul.

Of course, the Extreme Ice Pure Lotus can also be used to refine other pills, such as the Snow Mulberry Pill, which can repair a cultivator's dantian and golden core.

This is a mature Ice Lotus, and it is precisely because it is mature that it shines with light from time to time.

Li Mu carefully broke through the ice layer, collected the spiritual herb, and solemnly placed it in the jade box before storing it in his ring.

Li Mu was in high spirits after obtaining the spiritual treasures of heaven and earth. After descending the mountain, he once again came to the array gate at the foot of the mountain.

Looking through the portal, it was pitch black, so dark you couldn't see your hand in front of your face; even using your divine sense, you couldn't see very clearly.

As Li Mu entered the gate, he immediately felt an extreme chill wash over him.

The chill quickly froze his clothes as he moved, and the frozen fabric hissed as he moved.

After walking only a dozen steps, Li Mu sensed a hint of danger, which immediately put him on high alert.

As he ventured deeper into the mountain, the sense of danger grew stronger, and just as he was about to turn back...

A devastating, explosive aura rushed towards him, followed by a surge of powerful spiritual energy.

Bang!

Li Mu was like a kite with a broken string, sent flying by a single punch.

"Foundation Establishment cultivator!"
