Two months later.

Black Light Sea.

In a cave under the sea, the light shone brightly, and a figure appeared from it.

"Finally got away. ”

Wang Yuan exhaled lightly.

The ghost is really powerful.

The speed of the escape technique is terrifying, faster than that of ordinary monks in the foundation building period, after Wang Yuan encountered it, he suffered a lot, but fortunately, the body protection god was greatly completed, plus tens of thousands of runes and seals were consumed, and the array disk that was refined before was used, so he was trapped. Otherwise, there is a real possibility of serious injury this time.

The Water Yin Escape Technique urged, and Wang Yuan walked forward under the water.

The sea here is 1,003 feet deep.

Wang Yuan continued to sink and slowly came to the valley at the bottom of the sea here.

From the bottom of the sea, the sea sinks significantly, forming a plain in the middle of the mountains, and this plain is also very peculiar, surrounded by black willow trees, densely packed, completely enclosing the place.

Wang Yuan sank slowly, and saw the thick black willow wood.

"No wonder there is no sect in this place that wants to break it forcibly, not to mention the underground formation, just these black willow trees, I'm afraid it will take a lot of effort to be clear. ”

Black willow wood, although it is a third-order spirit wood, but like other spirit trees, as the age of the tree increases, the grade will also increase.

But...... Black willow wood is of little use.

It is extremely strong, but it is not suitable for refining magic weapons and so on.

Perhaps the only role is to refine sea ships.

But there are better options for refining sea ships.

The black willow wood in this place is so far away from the giant axe island, it is not convenient to collect and transport, naturally no one wants to come, and the underwater forest formed by the black willow wood is also extremely terrifying after so many years of accumulation here.

"If it continues like this, maybe in another million years, maybe this black willow wood will come out of shape?"

Wang Yuan had such an absurd idea in his heart.

Something like a spirit tree is very difficult to transform.

There is no one in a million to produce spiritual intelligence. It takes all kinds of conditions and coincidences.

It is unlikely that this black willow wood wants to transform into a shape.

Follow the bottom of the water and continue on your way.

It didn't take long for Wang Yuan to see pieces of mountains and rocks covered with a layer of rocks, and the mountains and rocks did not know how many years had been silent. There was a faint glow of various runes in the underside of the rock.

As soon as Wang Yuan saw it, he understood that this was a formation.

Airplanes!

The blue water sword, sacrificed, and Wang Yuan's sword fell.

The mountain stone cracked in an instant.

Underneath the rocks, a ray of light appeared, and the light was extremely heavy? Condensed? Isolate the inside from the outside world. Wang Yuan's sword is not even a tickle for this formation.

"This formation...... It's amazing. ”

Wang Yuan can be regarded as a first glimpse of the way in the formation technique? A sword falling? Seeing the indifference of this formation, you will know the power of this formation.

Walking along this seamount rock? Wang Yuan walked forward slowly.

When the Yin Yang Immortal Sect was broken, this was part of it.

And this part of the ruins? I don't know how many years have passed.

There is already a layer of mountain rocks on the surface.

Is there a current washing this area? You can still see the traces of the formation, but in some places, the mountains and rocks are towering, and the mud and sand are all over? Black willow trees growing again? There is no trace of it at all.

"According to the senior in the Buchengfei clan, the defective place of this formation should be in an area in the southeast, but when that senior came, it was hundreds of years ago, and the underwater environment had already changed? It is impossible to find a sword in a carved boat. ”

Wang Yuan quickly clarified his thoughts.

Keep searching.

Not long after, Wang Yuan discovered a cave in the middle of the rocks.

The cave is already half covered? But Wang Yuan's divine sense stretched out and did not see the end of this cave.

"The caves around here? Only this one is the deepest, and it stands to reason that this is it. ”

Wang Yuan's body forward? Pull the stone from the entrance of the cave with both hands? Then step into it.

Continuing to go deeper? The rocks in the cave have come together.

Wang Yuan had to keep the road open.

But the deeper he went, the happier Wang Yuan became.

After walking for more than half an hour and bypassing many detours, Wang Yuan finally came to the bottom of this mountain rock.

The layer below was extremely rich and incomparably light, enveloping the entire ruins, even if only this trace could be seen because of the mountain stones, Wang Yuan could feel the strength of this formation.

"This is it, according to the senior's statement, until the noon of the day of the Double Ninth Festival, when the power of the sun is at its peak, the formation here will have a short fluctuation, and you can take the opportunity to enter it at that time. ”

Wang Yuan muttered to himself, looking around.

Thick aura, unbreakable.

There was a faint yin and yang rune shining on it, Wang Yuan glanced at it a few times, and his brows furrowed slightly:

"Wait a minute, these yin and yang runes seem to be somewhat familiar!"

Wang Yuan was originally going to wait for three months, wait until the day of the Double Ninth Festival, and use the means of that senior to enter this formation, but now Wang Yuan has a different understanding.

Standing in front of this formation, Wang Yuan carefully looked at the runes shining above the formation.

Yin attribute runes, yang attribute runes, are a little peculiar.

Wang Yuan observed carefully, pondered, and his eyes showed a look of shock.

Then, Wang Yuan took out the jade slip and looked at it carefully.

Among the jade slips, there is the Pure Yang Diyuan Netherworld Water Scroll, which has a part of the third-level formation that can already be seen, the third-level formation is different from the second-level formation, it is more complicated, and it is difficult to comprehend.

Therefore, although Wang Yuan had enlightenment, he did not make much progress.

In addition, the energy was put into spell cultivation and polishing cultivation, and this three-level formation was rarely studied, but now seeing the runes on this formation, Wang Yuan took a closer look and found the clues.

"This formation...... It has some similarities with the third-order formation in the Pure Yang Earth Yuan Netherworld Flowing Water Scroll!"

Wang Yuan was convinced.

However, the Pure Yang Diyuan Netherworld Flowing Water Scroll is a practice practiced by the prince of the Northern King Immortal Dynasty, and this relic is the relic of the Yin Yang Immortal Sect back then, what connection can there be between the two?

Wang Yuan was a little confused.

But after this discovery, Wang Yuan had other ideas.

"This formation should be formed by combining more advanced formations, it won't be just a third-level formation, it's naturally impossible for me to break it, but if you want to enter it......"

Wang Yuan quickly deduced from the bottom of his heart, and his thinking gradually became clear.

Half a day later.

Wang Yuan stood up, pinched the magic trick in his hand, the yin and yang runes condensed around his body, and spiritual power poured out, and then Wang Yuan stepped towards the gray spiritual light.

The spiritual power on his hands was wrapped, and Wang Yuan seemed to have touched a stone.

The aura formed by the formation is thick and obscure.

But the next moment, a peculiar scene appeared.

As if the stone had melted, Wang Yuan's hands entered the spiritual light.

"Sure enough. ”

Wang Yuan stepped forward, and his body quickly entered the formation.

The formation seemed to be a layer of viscous liquid, and Wang Yuan could barely blend into it and move forward slowly.

Half a column of incense after that.

Wang Yuan's body crossed the formation aura and appeared in a misty space.

"This is inside the ruins?"

Wang Yuan looked at the chaotic and hundreds of mountains and rocks in this ruin, and his face was shocked.
