The pale black water of the river flows slowly.

The gurgling sound is incomparably clear in the veins deep in the earth.

Wang Yuan approached cautiously, holding a defensive shield in his hand.

The river flows slowly, and although it is pale black, it is not dirty.

Instead, it gives people an eerie sense of clarity.

And Wang Yuan observed carefully, and found a black shadow in the river, which blended into the black river water and was with the sand and gravel at the bottom of the river.

If you don't pay attention, you won't be able to find it.

"This is the rumored demon beast in the Black River. Tsk, the world is so big, I really don't know what type of demon beast this is?"

Wang Yuan secretly said that he was surprised in his heart.

Then walk around the side and walk over the stone road above the Black River.

Above the ground, there is a world.

This underground is also a world.

According to the previous life, there is also an ecosystem underground.

For example, in this vein, there are still a lot of low-level demon beasts, but in comparison, many disciples rarely enter the depths of the vein, so they naturally don't know.

For example, this black river is.

This mysterious demon beast in the black river is not strong, for the monks of the Ning Yuan period, this demon beast is not threatening, but for the monks of the Qi cultivation period, it is strong.

It is said that this demon beast is extremely fast and has a strong defense, once it is bitten by a demon beast and dragged directly into the black river, it will never come out again.

There are rumors about this.

When the Huangsha Jinyan vein was first discovered, there were several treasures in it, such as earth spirit milk, fire chalcedony, golden sunflower and so on. These treasures were of great help to the Qi cultivation period cultivators to advance to the Condensation Yuan Period, and at that time, countless Qi cultivation stage disciples in the Southern Kingdom and the Wei Kingdom entered the ore veins to search for these treasures.

Among them, the fighting continues.

It wasn't until these treasures were looted that several major sects took over.

In the end, this vein was occupied by the Qingyun Sect.

That's why Wang Yuan was able to get so much information from Old Man Lin.

After crossing the Black River, Wang Yuan continued to walk deeply.

It didn't take long for the surroundings to start changing.

The ore vein is still the ore vein, but a strange power appears around it, oppressing itself, the spiritual power becomes stagnant, and Wang Yuan sacrifices the yellow shield.

Only this time, the aura above the shield was much lower.

"Sure enough, there is a problem with the gravity here, and it seems that the Earth Dragon Cave is almost here. ”

Wang Yuan walked forward slowly.

The deeper you go, the lower the terrain becomes, and it looks like you've really entered a hole.

After swaying and walking cautiously for half an hour, Wang Yuan finally saw an entrance, and the terrain in front of him also calmed down.

"This is the Earth Dragon Cave. ”

Wang Yuan's eyes flashed with a hint of joy and continued to move forward.

Stepping forward, Wang Yuan's body swayed slightly, and he almost stumbled to his feet, only walking a few feet away, and the gravity around him increased by one percent.

One percent gravity, it doesn't seem like much.

But the effect is obvious.

The aura in the sea of dantian qi is becoming more and more stagnant, whether it is urging the magic weapon or casting the spell, it will be much slower and much weaker.

Now the strength of the sixth layer of Qi cultivation is estimated to be two or three percent less.

"It's no wonder that the other monks knew that this place had some benefits for cultivation, and they didn't want to come here, so their strength suddenly decreased, which was indeed a bit uncomfortable. ”

Wang Yuan shook his body.

Keep moving forward.

Didn't take a few steps.

In the distance, a yellow demon beast swooped out, this monster beast had a strong body, it looked like a lion, but it was only less than three feet tall, much smaller.

In addition, this demon beast is covered with a layer of stone armor, has horns on its head, and has a regular tail on its back, and its body is permeated with a unique and incomparable coercion.

Long Wei!

Oh!

As soon as the demon beast appeared, it killed it directly.

Wang Yuan's expression changed slightly, and the spells in his hands instantly condensed.

Even here, the Earth Escape Technique is performed extremely quickly.

Call!

The earthy yellow light under his feet shone, and Wang Yuan's body disappeared in an instant, appearing outside Zhangyu.

"Hmph, it's really difficult. ”

Wang Yuan waved his hand, and the water-blue spiritual water sword in his hand flew up, and then the law was pinched, and the spiritual water sword and water sword flew up, and around the spiritual water sword, a small piece of water mist appeared, and the water attribute aura converged into a brilliant sword light, which fell inadvertently.

The dragon beast of the land was rushing up, and it was hit by the spiritual water sword in one move.

Bang!

The Earth Dragon Beast fell to the ground with a bang, and the stone armor on its body fell to the ground.

The stone armor turned out to be made from earth-attribute ores, and on the back of the demon beast, a patch of green blood appeared.

Roar!

The Earth Dragon Beast roared angrily and disappeared into the passage beside it.

The body of the dragon beast in the passage is not much bigger, and if Wang Yuan wants to enter it, he can only bend his body, and it is not easy to chase.

"Ignore this monster for now. ”

"The Earth Dragon Cave has arrived, is the secret of cultivating such a spell as the Earth Magnetic Protector Divine Light here?"

Wang Yuan muttered to himself.

Find a position, set up the formation, and sit down cross-legged.

This formation was exactly what Wang Yuan didn't know about the surrounding of the ore vein before, and when he came in this time, he also put it away, and now as soon as it is arranged, the gap also appears.

The shield is more than half smaller than before, and the defense is much worse.

But it's better than nothing.

Wang Yuan sat in the formation and once again cast the divine light of the geomagnetic protective body.

This time, it's really different.

In the past, after casting this spell, after the runes were condensed, they collapsed in an instant, and they couldn't be sustained at all, no matter how hard Wang Yuan tried during this time, there was no change.

And this time, after the five runes slowly condensed, they turned out to be stable.

The earth-attribute spiritual power is input into it, and the surrounding earth-attribute aura gathers.

In an instant, a ray of light appeared around Wang Yuan.

"This ......"

Wang Yuan was a little confused.

I was about to make the next attempt, but at this time, the earthy yellow light shattered instantly, and disappeared again as before.

"What is the reason for this?"

Wang Yuan's face showed a hint of annoyance.

But at this time, Wang Yuan settled down, forcibly abandoned the disappointment in his heart, and continued to try.

Rune condensation.

Spiritual power is input into it, and the aura of the earth attribute gathers from all around.

An earthy yellow glow appears.

Wang Yuan was quietly in control.

After five breaths, the light dissipated again.

After this time, Wang Yuan's expression became solemn: "There doesn't seem to have changed anything, is it because of the gravity here, so that the runes can not collapse for a while?"

"No, if that's the case, then out of here, this spell can't be cast. In that case, why did the prompt ask me to come here? ”

"There must be somewhere, I didn't find. ”

Wang Yuan tried again.

The third time, there was no result.

The fourth time, there was no result.

Fifth, sixth......

Within half an hour, Wang Yuan experimented thirty-nine times.

This time, when the light dissipated again, a different light burst out in Wang Yuan's eyes:

"Yes, there has been a change, this time, this spell has increased the time of about half a breath compared to before, and the runes seem to have changed slightly. ”
