Immediately, Sun Cheng hurriedly locked the large area that disappeared, and once again let a small spirit dragon swim over, and after exploring for a while, this little spirit dragon also magically disappeared.

In such a strange place, even the little spirit dragon with spiritual power can absorb it, and it has become impossible to directly find out what the specific situation is.

However, Sun Cheng has also locked the specific direction, which should be where the formation projection node is located.

It was fifteen meters below the ground in the direction of the pavilion in the courtyard.

Sun Cheng came to the courtyard, directly moved the stone table in the small pavilion, uncovered the bluestone floor, and then took out the demon slayer knife and dug deep into the ground frantically.

Now it is the demon slayer knife of the beginner-level seventh-grade dragon pattern divine soldier, but it was used as a hoe by Sun Cheng, if other martial artists saw it, they would all vomit blood.

I don't take the baby seriously!

With the help of the dragon vein true yuan, the demon slayer knife is simply very sharp, whether it encounters dirt or rocks, with a single knife, it can directly split a deep pit.

In a few moments, a fifteen-meter-deep pit was dug out.

Bang!

Just after Sun Cheng slashed out, he slashed at a huge hard object, and after cleaning up a large amount of dirt, a jade-white circular compass the size of a square foot appeared in front of his eyes.

On the jade-white compass, there were nine dark dragon patterns circulating, flashing with a clear white light, as if a white mist had been condensed, wrapping the compass loomingly.

This jade-white compass should be the node of the projection of the entire magic circle.

The surrounding rocks had already been cleaned up, and the entire compass was suspended in the void like this, Sun Cheng tried, wanting to use the demon slaughter knife to push it away, but found that it couldn't be pushed at all, no matter how much strength was used.

Above the compass, chains of substance-like transparency loomed, extending into the endless void.

A faint dragon pattern appeared on these chains, shining with a strange light, linking the jade white compass with the entire Nine Dragons Lock Spirit Array.

And the entire compass is also fixed in an eternal position by these dragon chain chains. Unless Sun Cheng's strength could exceed the power of the entire Nine Dragons Lock Spirit Array, otherwise, he would not be able to move this compass in the slightest.

Of course, his purpose was not to move the compass, but just to find out the cause of the problem with the magic circle.

Sun Cheng locked his gaze on the jade-white compass and observed it carefully.

On the compass, in addition to the dragon pattern embossing around the perimeter, in the middle of it, is a fist-sized hole.

In this hole, it was as if there was an infinite world, and the entire area covered by the Nine Dragons Locking Spirit Array was reflected in it one by one.

It's a mystery.

Sun Cheng knew that under normal circumstances, this pit was a tiny source of spiritual energy, and the spiritual energy condensed by the Nine Dragons Lock Spirit Array passed through here, projected over, and finally enveloped in the entire small courtyard.

Since everything is normal, and this compass is still closely connected to the entire Nine Dragons Lock Spirit Array, why did there be an accident in the ninth of this East Courtyard?

For a while, Sun Cheng was completely confused.

Is everything going to work? So I'm going to think about how the devouring black hole works. Immediately, with a wave of Sun Cheng's big hand, a red True Yuan ball was projected out of his hand.

As soon as the red True Yuan Ball appeared, a devouring black hole appeared out of thin air in the void in front of it, devouring the True Yuan Ball in an instant, and then disappeared without a trace.

If it weren't for Sun Cheng's quick opportunity and suppressing the dragon vein true element in his body, I am afraid that he would have absorbed this strange appearance but strange disappearance of the devouring black hole.

"Hehe, there's a problem. ”

In the pit in the center of the compass, there was a transparent flying insect the size of a thumb.

This flying insect was completely invisible, and it was only at the moment when it devoured the red true element ball just now that it emitted a fleeting white light, and only then did it reveal its true form.

If Sun Cheng's gaze hadn't been locked on the pit of the compass just now, he wouldn't have noticed this abnormality at all.

"This bug just now should be the Void Moth. ”

Sun Cheng pondered for a long time, and then finally confirmed the root and foot of the mysterious flying insect.

Between heaven and earth, there is a list of strange insects, and there are 3,000 kinds of strange insects, all of which are listed on it. And this void borer is the insect that ranks three hundred and twenty-seven on the list of alien insects, this insect can swim in the void and devour all kinds of energy.

However, the Void Borer is extremely rare, and it is rare to see one in the entire Longwu Continent for thousands of years, even if Sun Cheng had never seen it in his previous life, he didn't think that in this White Tiger City, he could accidentally find one.

The void borer in front of him, I am afraid that when he was cruising in the void, he discovered this magic circle projection node, and sensed that there was a distant and continuous gushing of spiritual energy here, so he threw himself into the compass pit, wanting to absorb the spiritual energy to his heart's content.

But unfortunately, after entering the compass pit, this void borer was imprisoned by the infinite power in the Nine Dragons Lock Spirit Array, and it was easy to enter, but it could no longer escape.

And with the blessing of the Nine Dragons Locking Spirit Array, the Void Moth's energy-devouring ability was amplified hundreds of times, turning the entire courtyard into a forbidden place. As long as there is an energy fluctuation, whether it is the aura or the true element, it will be swallowed up by the devouring black hole formed by the void borer in an instant.

Now that he has understood the problem, Sun Chengcheng is to find a way to change this situation.

"Under the impetus of the magic circle, the energy devoured by this void borer can be called terrifying, with its small body, it is impossible to digest such a huge amount of energy, it is very likely that it has passed through the Nine Dragons Lock Spirit Array, transformed into spiritual energy, and moved to other places. ”

"In this way, if you can reverse the direction of the Devouring Black Hole of the Void Moth, go towards the Nine Dragons Lock Spirit Great Array, devour the spiritual energy from the large array, and release it in the small courtyard, then within the ninth number of the East Courtyard, it is very likely to become a cave heaven treasure with rich spiritual energy. ”

With ideas, Sun Cheng's heart broadened.

Then he prepared nine red True Yuan balls in a row, and they were projected one after another, all of which were devoured by the Devouring Black Hole extremely quickly.

Under the continuous supply of the True Yuan Ball, the specific form of the Void Borer was finally completely presented in front of Sun Cheng's eyes.

At this time, he realized that the state of this void borer was extremely strange, and he could only see half of his body. The thumb-length body, the head and front half of the body are exposed in the compass pits, while the lower half of the body is hidden.
