The nine-tailed sky fox is actually called the nine-tailed demon fox, which is more accurate.

The Nine-Tailed Sky Fox is, of course, self-proclaimed, but more often than not, it is called the Nine-Tailed Demon Fox.

Because they were originally demons.

It's just that it belongs to the kind of big demon that existed in ancient times, and once it becomes an adult, it has the ability to penetrate the heavens and the earth.

Approaching God.

And the demon world is the hometown of the nine-tailed demon fox.

Whether the little fox is the soul projection of the nine-tailed demon fox or not, Lu Chen does not know.

But one thing is certain, if the nine-tailed demon fox can return to the demon world, its strength will definitely be greatly improved.

"You're saying the Demon Realm is behind this rock...... It's just a wall, is the spiritual power really purer?" Lu Chen asked quietly.

Of course, in fact, her heart was full of shock.

Not because of the identity of the little fox, but because of the thought that between the two worlds, there was such a plain-looking stone wall.

It's a bit unbelievable!

In addition, Lu Chen actually knew very well in his heart, not to mention that the era of the end of the law was coming, even in the ancient period, the spiritual power of the human realm was far inferior to that of the other six realms.

It is really because human beings are the spirits of all things, and the laws of heaven, for the sake of balance, themselves limit the growth of human beings.

Otherwise, if everyone has the same resources, the human race will rely on its super reproduction ability to build a powerful human army, and eventually it will inevitably unify the Seven Realms.

It can be said that humanity has lost at the starting line in terms of resources from the very beginning.

Therefore, while Lu Chen was full of curiosity about the demon world in the mouth of the little fox, his mind also became active.

There is a more intense and pure spiritual power in it, and it can be directly absorbed without even special refining.

If a cultivator enters this demon realm to cultivate, it will definitely get twice the result with half the effort.

And because Lu Chen himself has the assistance of the Eye of Merit, once he cultivates in this atmosphere, he will definitely be able to break through the ground level in a day.

The most important thing is that if you can enter it to cultivate, you will no longer have to worry about the suppression of the Heavenly Dao in the human world now, and the earth level will naturally not become a gap in cultivation.

In fact, at this time, Lu Chen couldn't help but think of his father and mother.

Father Lu Qingtian may have had the help of the Eye of Merit, so he successfully broke through to the ground level before the age of 30.

And what about the mother?

He must also have the strength of the ground level, so he can become the testimony of the Liangyi formation outside with his father.

In this way, all this is definitely not a coincidence, but there is a special reason.

Lu Chen even boldly guessed that the little fox was inextricably linked with his parents, and it was likely that the reason why his father and mother were able to successfully break through the ground was because of the inseparable relationship with the little fox.

If he was more daring, Lu Chen was thinking about whether his father and mother had ever entered the demon world!

And it was precisely because he had understood the power of the demon realm that he resolutely activated the Liangyi Formation to seal it when the Seven Realms Passage was about to collapse.

These ideas seem to be unfounded, but once they appear in Lu Chen's mind, they can no longer linger.

Lu Chen felt that he seemed to be getting closer and closer to this truth.

It seemed that he found that Lu Chen fell into silence, and the little fox was a little anxious.

"My lord, this can't be said to be a wall, but behind this wall, there is a spatial crack!"

"Spatial Crack ......" Lu Chen's brows jumped unconsciously.

It's exactly what I guessed.

The point is that the little fox seems to be a little anxious.

However, now was not the time to think about anything else, Lu Chen also wanted to take a look at the magic of the world behind this wall.

Lu Chen didn't hesitate at all, and took a few steps forward directly, standing in front of the rock wall.

He set his eyes on Lin Siyun and said to her seriously, "Miss Lin, you can help me see which part of this rock wall has more strong spiritual power fluctuations. ”

Lin Siyun nodded immediately after hearing Lu Chen's words.

Immediately, she once again stretched out her palm and pressed against the rock wall.

Lin Siyun sensed the fluctuations of spiritual power little by little, and distinguished the differences.

The spiritual power itself here is relatively rich, and it is necessary to get rid of interference and find the purest spiritual power.

Even Lu Chen couldn't do this.

You have to be like Lin Siyun, a person with an innate spiritual vein, to be able to distinguish by that little bit of subtle difference.

Of course, for the sake of insurance, Lu Chen still put his hand on Lin Siyun's back again, injecting a wisp of merit power to assist.

Nearly two minutes passed, and Lin Siyun finally made a new discovery.

"Just two meters to the left. ”

Lin Siyun suddenly opened his eyes, and his gaze fell on the rock wall on his left.

"Right here?"

Lu Chen was overjoyed in his heart, and immediately walked over and stood at the place where Lin Siyun pointed his finger.

Turning around again, after Lin Siyun was sure, Lu Chen nodded, took a step back, took a deep breath, and the power of merit in his body worked throughout his body, and finally gathered in his palms almost frantically.

Half-step crash fist!

Lu Chen turned his palm into a fist, and with a light cry in his mouth, the strength of his whole body suddenly exploded, and his fists slammed down on the rock wall.

As their fists collided with the rock wall, there was a loud boom that echoed through the space at the end of the cavern.

Lu Chen just threw a tentative punch, but he clearly saw that a clearly visible crack began to spread out of the rock wall.

Immediately afterward, the hard rock wall cracked at a rate visible to the naked eye.

These cracks were centered on Lu Chen's iron fist, stretching out in a radial shape, covering the entire rock wall in just one second.

Lu Chen's eyes looked at the rock wall in front of him in a daze.

There was some excitement in his heart.

The power of this punch had already surpassed his previous estimates.

It seems that it is also due to the recent growth of the power of merit, plus when he punched just now, he used the surrounding spiritual power to some extent, so it produced such an immediate effect.

Of course, Lu Chen didn't have much thought about it at this time, why this punch was so amazing.

In his heart, he only had a strong curiosity about this new world that might appear on the other side.

In addition to that, there is a little bit of fear.

It was really because of the existence of his parents that he was so nervous about the opening of the Seven Realms Passage, and he was even willing to become a testimony desperately and activate the Liangyi Formation to seal it.

Lu Chen even had a hint of hesitation, should he do this?

Will this lead to incalculable consequences?

However, after thinking about it, Lu Chen felt that this was not the scope covered by the Liangyi Formation, but there were still cracks, could it not be as he imagined?

The little fox seemed to see what Lu Chen was suspicious about, and then explained the reason to him.
