The Proving Ground is a cave near the wall of the Black Mountain, and in front of the gate there are two statues of black animals that look like cats, not cats, dogs, and not dogs.

The ground was inlaid with black pearls the size of a dragon's eye, and a piece of blue light flashed from the ground from time to time, spreading into the depths of the cave.

The blue light illuminates the darkness of the cave again and again, and then quickly disappears.

I could faintly see that there were many sharp white stalagmites hanging from all over the place. There also seem to be many sculptures of mysterious silhouettes on both sides.

"This is the place of trial. ”

Deputy City Lord Ye Zifeng stopped at the entrance of the cave.

"Your Royal Highness the Prince, the content of the trial is to enter it and stay for three days and three nights. ”

"Stay for three days and three nights?" Lin Xin narrowed his eyes slightly. "It's that simple, what's in it?"

Ye Zifeng shook his head.

"We don't know, Your Highness, this is the content of the trial that has been handed down from ancient times to the present, even if it is the Yuanjing Patriarch, if he enters with insufficient strength, it will be a dead end. It is said to be related to the key to the prison formation of this Thousand Hells City. Even as the deputy city lord, I don't know very well. ”

Nan Shunqing said slightly coldly.

"This is clearly an extremely strong confined space, right? What if the teacher enters and the big array is activated outside to seal the entrances and exits? Who will ensure the fairness and safety of the trial?"

What he asked was exactly what Lin Xin wanted to ask.

The formation on the ground in front of him is not just as simple as blocking the big array, but in fact, it is a special five-grade formation that links another space, this kind of formation, if one is accidentally shuttled too far, if he wants to come back, he is afraid that it will be countless years later.

Even if he was well versed in the way of the formation talisman, he didn't dare to take it lightly.

Standing in front of the entrance of the cave, he also stopped at this time.

Ye Zifeng didn't know that this concern would appear, but he also smiled bitterly and didn't know how to answer.

Broken Chizi stood aside and was silent. She and Huang Ape Zhenjun have a deeper relationship, and they are very unfamiliar with this junior brother who has never had much contact, and they are different from each other, so they naturally hope that Lin Xin will simply turn around.

The group just stood at the entrance of the trial ground and froze.

Lin Xin stood with his hands in his hands, silent, just looking at the formation at the gate and squinting slightly. I don't know what I'm thinking.

Others knew that he was in a bit extreme. The fluctuations are large, and they don't dare to make any noise, no one knows what is in the trial, and it is natural to have some concerns and hesitation. So everyone waited quietly.

After a while, half an hour passed.

In mid-air, another black line flew in the distance.

It swooped down on the ground behind everyone.

"Not long after parting, the junior brother has greatly improved his strength, and he has actually reached this point, congratulations!"

The voice of the person who came was coquettish, and a close-fitting black dress could only cover one-third of the thighs, as if the breeze was a little stronger. You can see the mysterious ********.

The figure is even more concave and convex, and the appearance is delicate and charming, and it is the eldest princess kennel Sakura that Lin Xin has seen before.

"See Her Royal Highness Princess Celestia!"

Ye Zifeng led everyone and hurriedly saluted.

Kennel Sakura's eyes fell straight on Lin Xin, and there was a trace of burning in her eyes. Approaching the past.

"What's the matter?

Lin Xin smiled and glanced at her.

"You must enter, but how can you ensure that this testing ground is not controlled and blocked by outsiders?"

Kennel Sakura laughed. "It's not simple, there are only a very small part of this formation that can be controlled. The rest are ancient formations. The Founding Patriarch designed to absorb the power of the Demon God. The junior disciple is the Formation Fu Dao Grandmaster, and if he is controlled by himself, won't all the doubts be dispelled?"

The Yuan Dou Demon Sect does not have a grandmaster-level array talisman master. Lin Xin knows this.

The material resources that need to be consumed by the array rune are too terrifying, to reach the grandmaster level, it will take at least thousands of years of full strength to accumulate supply, relying on massive resources to pile up, in order to be able to pile one, this still requires the genius seed of the array rune to grow safely.

Lin Xin didn't have skills in hand. If you succeed once, you can replicate the second, third, and umteenth successes. Huge amount of resources are saved.

I'm afraid that with his original qualifications, he wants to reach the grandmaster level. Don't even think about it.

Hearing Sakura's words from the kennel, Broken Pond's face changed slightly.

"Senior sister's words are wrong, this second trial is to test the courage side, outsiders are not allowed to interfere, do you want to take the initiative to reveal the inside information, resulting in the failure of the trial?"

"Senior sister is serious. Kennel Sakura smiled, and the snow-white **** faintly revealed a trace of furrow from the black skirt.

"Sect competition, if this hint can affect success or failure, then the position of sect master is inevitably too easy to handle. ”

Broken Chizi stared at her coldly and didn't say a word.

Kennel Sakura also did not let it at all.

The confrontation between the two women is inexplicable, and it seems that they do not get along as harmoniously as rumored.

Lin Xin stood aside, and only he could interject among those present, and the rest of them were all cultivators or not have enough status.

"Could the teacher have entered this trial in the first place?" he asked lightly.

"Naturally entered. Broken Pond nodded.

"Can anyone take the formation?"

"Naturally!"

"Who?"

"It's the city lord of Yin Pengzi. ”

"I don't have enough strength in this seat, and I can't trust everyone present, but I also want to join the formation, I don't know how to teach me?" Lin Xin said lightly.

Broken Chizi was stunned when he heard this, and looked at Lin Xin carefully.

"Uncle Bai Chainzi has always been at odds with the teacher, and when she failed to compete for the position of sect master, she can ask her old man to be the leader. ”

"Not really. Lin Xin smiled. Reach out and lightly void a little on the ground formation.

Phew!

The invisible finger force was struck, and the ground formation was broken with a small trace in an instant.

Silently, the formation quickly dimmed, and the original flickering blue light disappeared in an instant, and the entire ground completely turned into an ordinary rune pattern carving, which was useless.

"The formation is under my control for the time being, do you have any opinions?"

Lin Xin looked at it for a while, and the purpose was to see through this formation.

With his Grandmaster Formation Dao, it is also possible to modify and control this big array a little.

The Yuan Dou Demon Sect did not have a formation mage who could control the ancient formation, and if he didn't dare to enter like this, it would really make people see clearly.

"Senior brother, please. The pupils of Broken Chizi shrank slightly, but his mouth replied silently.

She was shocked. Such a thousand-year-old formation, even if it was not a large array designed by the original founding patriarch, but this part of the trial ground was also integrated as an ancient formation formation, and it was able to find a way to control it so quickly and quickly seize part of the control.

This kind of array talisman attainment is indeed terrifying.

If it is a five-rank grandmaster, it is so terrifying. Aren't all those mountain protection arrays of the major sects and sects in vain?!

Lin Xin stretched out his hand to point out the key points of the formation, then nodded, and strode towards the entrance of the cave.

The formation failed, but after only a few breaths of time after entering the black hole, he felt that the upper and lower squares were upside down and chaotic, and the whole person was instantly distorted and teleported from one place to another.

"Sure enough, it's teleportation!"

Lin Xin's heart was slightly settled.

Wait until the teleportation is complete before looking around around for a look.

He had only entered the cave for more than ten meters, and he had already reached the sky above an extremely vast black plain.

Below is a vast wasteland with no trees. There are no lakes and streams, and there are no meadows.

There was only a patch of pitch-black dirt.

In the sky, countless extremely long black whiskers like silk threads floated and flew everywhere. Occupies almost all of the surrounding sky vision.

Some of these black lines are very short, only a few meters long, and some are extremely long, and there are not a few that are hundreds of meters or even thousands of meters.

And occasionally wriggle from time to time, like a live worm. Arch and even crawl in the air.

It's like a green worm crawling on the ground.

"This is the content of the trial? stay for three days and three nights?"

Lin Xin was vigilant, since he was just staying for a full time. Obviously, there is a mysterious danger here, otherwise there would be no trial, and the content is just the so-called full time.

Sure enough!

In the blink of an eye, above the sky, a black line tens of thousands of meters long swooped down.

The black line seemed to have a very purposeful effect, and it shot directly at Lin Xinfei.

Its speed is extremely fast, and the distance of dozens of miles is only available in the blink of an eye.

Lin Xin's brows jumped slightly. Demon luck, a withered dome phantom appeared behind him, and a sword light was fiercely condensed and slashed towards the black line.

Clang!

In the symphony of gold and iron.

The black line was not afraid, but it shook without the slightest pause. Continue to rush straight towards Lin Xin.

"Interesting!"

Fifty percent of his strength couldn't stop its momentum, and Lin Xin knew that it couldn't be defeated.

Dodge and retreated, the dodge attribute was as high as two thousand points, making his ability to predict danger extremely strong, even in Yuanjing, I am afraid that there are many talents in the bloodline of the divine beast, and it may not be as magical as him.

The black line narrowly brushed past him, and he shot out into the distance before he could castrate.

Phew!

Suddenly, Lin Xin's complexion changed, and he suddenly saw something on the surface of the black line, and flashed to the left in an instant.

A black thread of the head just pierced out from his original position, and it directly penetrated the space and escaped directly!

"This is !?"

He dodged to the right again, and another black line pierced the space, rushing out of his original position.

For a while, he dodged again and again, and the speed of the black line was extremely terrifying, almost like breathing through space, piercing the spatial rules in the surrounding area into thousands of holes.

Its speed was lightning, and it was almost useless before continuing to shuttle.

Since Lin Xin recognized what this was, he no longer had any intention of resisting contact.

"Nine curved insects! I can't imagine that there are still demon insects that have long been extinct in the primeval era!"

"It's just that the Nine Curved Worms can freely shuttle through space and devour Yin Qi, how can there still be formation patterns on their bodies?

Lin Xin was puzzled.

The body kept moving like lightning, and every time it was a fraction of a millimeter of continuous dodge from the attacks of the Nine Curves.

Its sophistication is no less than the most top-of-the-line dodging techniques.

He is aware of the trouble of this worm.

Its body is extremely strong, and it can freely gnaw at space, create hollow shuttles, and feed on yin qi.

The most important thing is that this insect is a creature that must be introduced into the body after the formation of the withered dome demon body is completed.

If you want to break through the ninth layer, you need a strong enough withered demon body, and then introduce this worm, let it live in the body as a parasite, devour the impurities of the demon body, and transform it into a special substance that can nourish the demon body more and make it more perfect and higher.
