Sun Cheng entered the main room, and the bedding on the bed had long since decayed after a hundred years, and when he cleaned it before, he directly disposed of it together.

On the ground next to the bed, there was a jade-colored futon, and Sun Cheng was not polite, sitting cross-legged on the futon.

If he wanted to understand the secrets of devouring vitality and essence blood in this courtyard, he had to try it himself first.

Immediately, after Sun Cheng sat down, he began to transport the hidden dragon chapter of the "Ancient Dragon Divine Formula", urging the true yuan in his own meridians. However, he knew that there was a big problem here, and he did not completely let go of the exercises, and only used fifty percent of the effect.

At the moment when the true element in his body was running, Sun Cheng suddenly felt that the vitality in the entire courtyard fluctuated violently, and then in the ground below him, an extremely strange devouring vortex appeared out of thin air, just like a real black hole, generating a huge suction.

Almost immediately, the True Yuan and Essence Blood in his body were completely uncontrolled, attracted by this devouring vortex, and quickly withdrawn.

This feeling is the same as the feeling of extracting all the essence of the body the moment the lightning eye opens. And it seems to be a little more terrifying. After all, the extraction of the Eye of Lightning is still orderly, and it can leave some basic blood and qi, allowing Sun Cheng to leave a life, but this time the extraction is completely violent and disorderly.

In just the blink of an eye, Sun Chengcheng felt that all the essence blood and true yuan in his body were swallowed by one-third. Immediately, he was taken aback, and hurriedly forcibly stopped his luck through a strong mind.

Fortunately, Sun Cheng kept a hand at the beginning, but it only took half of his strength to get lucky, and the technique of "Ancient Dragon Divine Technique" was strong enough, and his control over the true yuan was almost invincible, so he could rely on his strong willpower to get out.

Otherwise, as long as he delays for a while and a half, he will most likely be drained of his essence and blood and die.

Even if he was lucky enough to escape, after Sun Cheng broke away from the luck, the whole person was still panting like a cow, sweating profusely, and completely soaked.

With such a personal experience, Sun Cheng still doesn't understand. It was precisely because of such a terrifying devouring vortex that more than a hundred years ago, those outer disciples who lived here were estimated to have been devoured by the blood and qi of their whole bodies and died at the moment of pranayama luck.

It's just that even he can find out through the true yuan, more than a hundred years ago, those who were in charge of the affairs of the halls, at least had the great masters of the Lingwu Realm four levels of cultivation or above, how could they not be able to find out?

But in the end, they all remained silent and didn't say anything, so they banned the entire East Courtyard No. 9. If there is no oddity in this, no one will believe it.

The situation here is probably really the same as he expected at the beginning, the Nine Dragons Lock Spirit Great Array, this powerful magic array that can be called the foundation of the Heavenly Sword Martial Mansion, is a problem.

And the node of this problem should also be in this small courtyard.

With the grade of the Nine Dragons Lock Spirit Great Array, as well as the importance of the Martial Mansion, it is estimated that it had been built as early as 10,000 years ago, when the Heavenly Sword Martial Mansion was first established.

If you want to arrange such a powerful magic circle that has reached the high-level nine-rank, in addition to the infinite materials and treasures, you also need a high-level nine-rank dragon pattern master to make it possible.

Looking at the entire White Tiger City now, it is impossible to find a martial arts powerhouse who has been cultivated in the Xuanwu Realm Nine Levels. As for those with a higher status and strength, the high-level nine-rank dragon pattern master, I'm afraid there is even less.

Therefore, after there was a problem with this Nine Dragons Lock Spirit Array, it was impossible for the Heavenly Sword Martial Mansion to find a suitable dragon pattern master to repair it.

There is another one, since this Nine Dragons Lock Spirit Array can still maintain normal operation, it means that the problem is not serious, and the high-level of the Martial Mansion is not urgent to repair the magic array, but the courtyard of the East Courtyard No. 9 has been sealed.

This is why the heads of several halls back then have been shutting down one by one, and I am afraid that they have all received gag orders from the high-level of the martial arts.

Now that a hundred years have passed, time has long passed, and Wang Guiren, the current head of the secretary hall, may not know the situation at that time, but only thinks that there is really a problem with No. 9 of the East Courtyard, and in order to suppress Sun Cheng, he agreed to arrange his residence here.

For ordinary outer disciples, if they were to be placed in the ninth place of the East Courtyard, I am afraid it would be a very miserable thing.

But for Sun Cheng, it may not be.

The Nine Dragons Lock Spirit Array can give countless disciples of the entire Heavenly Sword Martial Mansion cultivation and supply infinite spiritual energy. But these auras were not created out of thin air, but were transformed by devouring various forces from elsewhere, such as the Endless Void and the Underground Abyss.

Normally, as a courtyard for outer disciples, No. 9 of the East Courtyard can enjoy the projection of the Nine Dragons Lock Spirit Array, supplying a certain amount of spiritual energy.

But now it has become a terrifying devouring force, and there should only be one possibility, that is, there is a problem with the node of the projection of this magic circle, reversing the effect of supplying aura, turning it into devouring all power, and transforming it into aura to supply elsewhere.

As a Martial Emperor in his previous life, Sun Cheng didn't know much about the Dragon Pattern Master, so of course he couldn't do it if he was asked to repair such a powerful Dragon Pattern Array as the Nine Dragons Lock Spirit Array.

However, if you take advantage of this problem of the projection node of the magic circle and take advantage of the loophole, you may reverse the problem of devouring all power into a gushing infinite aura.

With the knowledge of his previous life, he may not be unable to do this, as long as he succeeds, this East Courtyard No. 9 may turn from a dead place into a real cultivation treasure land.

Thinking of this possibility, Sun Cheng's heart was full of enthusiasm.

After resting for a while and recovering his state, Sun Cheng said he would do it. In order to reverse the situation, we must first find the true location of the projection node of the magic circle.

Immediately, Sun Cheng sat cross-legged and released all the five spiritual power little spirit dragons in the sea of consciousness.

Now, if his five little spirit dragons were to exert their full strength, they would be able to investigate the situation one hundred and fifty meters away, but the distance was too far, and it was impossible to do everything.

But this time he didn't have to be so troublesome, just locked the target in the small courtyard, five small red spirit dragons, shuttled back and forth in the void to investigate, all-round, no dead ends, every inch of the entire courtyard did not pull down.

Soon, with Sun as the central point, covering a sphere with a radius of twenty meters, all the details were presented in his mind, whether it was under the ground or in mid-air.

But nothing out of the ordinary was found.

An hour, two hours...... Sun Cheng controlled the five little spirit dragons, wandering through the void over and over again, scrutinizing them.

Nine hours passed, and there was still no gain.

"Could it be that your assumptions are wrong?"

At this moment, Sun CD couldn't help but doubt in his heart, but his willpower was extremely strong, and he immediately extinguished this trace of doubt.

Until the next morning, when the sun first rose, the sun shone in through the windows.

Just when Sun Cheng was almost numb, he suddenly found that one of his spiritual power little spirit dragons had disappeared, and the disappearance was inexplicable, and he didn't even be able to react at the first time.

Suddenly, Sun Cheng became ecstatic. The disappearance of a little spirit dragon certainly made him feel distressed, but if there is a situation, it is equivalent to the best news.
