It's just that the only difference is that at that time, he had the help of Jiuyang's remnant sun star, but now he can only rely on his own comprehension of the laws of space to fight the enemy, which is relatively more difficult.

Xiao Yu was not in a hurry, always maintained enough patience and meticulousness, and even covered the vast area with his divine sense, perceiving all the movements in the space.

"Boom!"

Xiao Yu explores with the "Way of Yu", trying to find a way out, but once again hits a wall, as if hitting a real wall.

Although space is invisible, there are actually barriers, and these barriers are more complex and powerful than reality, but they are difficult to perceive.

"The Way of the Universe" encompasses all possible spaces, no matter how complex and changeable, you can find the final passage, and you can turn into a new space in any space, but at this moment, Xiao Yu has been perceiving for a long time, but he has repeatedly hit a wall, and every time he thinks he wants to find the answer, he will eventually find that there is no road ahead at all.

It's like a peerless master hiding in the dark, watching what he's doing, trying to treat him like a doll, giving him infinite possibilities, and finally cutting off all these possibilities to kill his fighting spirit.

If it were someone else, it would be easy to lose confidence and patience in the face of this situation, but Xiao Yu was different, the thousands of lives he had experienced and the countless trials he had undergone were enough to support him to maintain the most peaceful state of mind.

In Xiao Yu's opinion, it is not so much that there is no hope at all, but as the only threat that space can pose, if the wear of his mind, trapping him in this place forever is the offensive it can launch, then Xiao Yu is happy, because it means that as long as the belief in his heart is not lost, he will definitely be able to find the final answer.

Thinking like this, Xiao Yu's mind became more and more settled, Jiuyang was perceiving the space while quietly observing Xiao Yu's changes, originally worried that he would be discouraged, but he didn't expect that the longer the time, the firmer his mind became. He has always been familiar with Xiao Yu, but now he feels a little surprised, in the step-by-step and down-to-earth cultivation of martial arts, Xiao Yu has become more and more powerful, and more and more, he can no longer see through what Xiao Yu thinks and does.

For him, this is both a relief and a loss, and all those who pass on one body to another person may have such thoughts, but in the end, those losses will all turn into relief.

"Boom!"

Jiuyang's eyebrows were slightly furrowed, he was also hit by the invisible barrier, and his heart suddenly gave birth to three points of confusion, his realm was almost inferior to Xiao Yu.

The divine thought moved slightly, and in an instant, it was as stable as Mount Tai, and it did not move.

In the silent void space, all time seems to stand still, and no one knows what is happening inside, not even those who control it.

In this still time, Xiao Yu conjured up all the possibilities of space, but no matter how he changed, he was always like driving a flat boat on the boundless rivers and seas, unable to find any direction.

Xiao Yu slowly inhaled a breath, swallowing a wisp of shallow restlessness, after a long exploration just now, his cognition of the surrounding space was still at the beginning, while precipitating his emotions, while moaning in a low voice.

According to common sense, he has been perceiving the "way of the universe" for so long, it should be impossible to never move an inch, just like when this heavy space first appeared, he and Jiuyang each tested with their palms, although the distance is extremely short, but there is still a distance, it should definitely not be like now, even the surrounding square inch can not be perceived.

However, although Xiao Yu guessed that there might be something strange, it was difficult to find what this strangeness was, and so far he still had no clue.

Xiao Yu exhaled the breath just now, and inhaled it gently, in the face of this situation, he already knew very well how to adjust his emotions.

"The Way of the Universe" can transform all possible spaces, with the extent he currently masters, as long as there is a glimmer of possibility, he should have a chance to break through, perhaps, but the time he has insisted on is not enough.

Xiao Yu thought like this, his mind became calmer and calmer, and suddenly his heart flashed, as if a lightning bolt crossed the night sky, "Jiuyang, within the Three Realms, is there an impossible space?"

"The Way of the Universe" can explore all possible spaces, if there is no progress for a long time, it is possible that it is an impossible space because of what he has encountered, although he doesn't know if there is a concept of impossible space, he still can't help but ask Jiuyang.

Xiao Yu asked suddenly, and Jiuyang was also stunned, and then understood what Xiao Yu was asking, and pondered for a moment before saying, "Yes." ”

Xiao Yu was also surprised and delighted, he didn't expect that there was really no room for impossibility, he was originally just guessing at random, maybe it was the answer.

"It's impossible, but it's relative. ”

Xiao Yu frowned, "I don't understand." ”

Jiuyang Dao, "Within the Three Realms, I don't know if there is really an impossible space, but compared to the Beidou Heavenly Source, there is indeed an impossible space. ”

Xiao Yu's eyes lit up slightly, "Great Immortal, what do you mean is that the laws contained in the Beidou Heavenly Source do not encompass the Three Realms, and if there is anyone outside the laws of the Beidou Heavenly Source, it is called impossible." ”

Jiuyang bowed, "Yes, but there is one thing that needs to be corrected, the Beidou Tianyuan's 'Way of Universe' is vast and profound, all-encompassing, and those who can be outside the 'Way of Universe' laws are some of the laws of space that exist but have not been discovered, and only a very small part of them are the impossible spaces that can override the 'Way of Universe'." ”

Xiao Yu became more and more aware and muttered, "In addition to what you just said, is there a truly impossible space, this kind of space originally existed, but it is called an impossible space, the two are completely contradictory, with the size of the Three Realms, is there such a space?"

Jiuyang smiled and shook his head, "This is not something I can know, you refine the Beidou Heavenly Source, and you have the Phaseless Heavenly Book, maybe you can give me this answer in the future, but even if this kind of space exists, it is definitely not something that the small Emperor Continent can bear." ”

Xiao Yu nodded, and then asked, "If it is a space that is above the 'Dao of Yu', how can it be broken?"

Jiuyang Dao, "Since it is above it, it is naturally difficult to break through, but it is not a concept to be above it and include the 'way of Yu', do you know what I mean." ”

Xiao Yu was stunned for a moment, and said thoughtfully, "You mean, even if the laws contained in this impossible space are higher, it can't form an absolute restriction on the 'way of the universe'?"

Jiuyang smiled, "Naturally not, with the essence of the Beidou Heavenly Source, after tens of millions of years of tempering, although there are only those that are not in its barriers, it is also not in other barriers." ”
