All Heaven and Worlds Bookstore System

In the bang, Yang Xiao immediately aroused the state of Chaodouzhan Saint Body Red.

After leaving the battle group before, Yang Xiao withdrew from the transformation, not wanting to waste mana in vain.

Seeing Yang Xiao's aura suddenly increased a lot, the faces of the creatures in the underworld were extremely ugly.

But immediately, the underworld creatures reacted, and became extremely angry just like the previous underworld creatures.

"It turns out that you are those **** fighting saints. Since I met you, you don't want to live."

Yang Xiao was speechless for a while, what did the fighting saints do to make these underworld creatures so angry.

After contacting the answers of the two creatures in the underworld, this fighting saint seemed to have run into the underworld to kill.

But at this time, Yang Xiao couldn't care about so much, the angry creatures in the underworld had already attacked him.

Yang Xiao snorted, the endless sword energy reappeared.

The sword shadow whizzed, the sword aura was vertical and horizontal, and Yang Xiao could not be seen at all.

The creatures in the underworld roared endlessly, looking for Yang Xiao's body, but how could they find it.

This creature of the Yin Realm was not even stronger than the one Yang Xiao had dealt with before.

Yang Xiao slashed indiscriminately, and directly cut many scars on this underworld creature.

After hacking for a while, Yang Xiao suddenly stopped and cast Thunder Purgatory.

The thunder was rolling, and the creatures in the underworld were screamed and screamed.

Taking advantage of this time, a long sword flashed in Yang Xiao's hand, and the Qi of the Thousand Tribulations Slaughter Sword plunged into the Thunder Purgatory to assist in the killing.

In the other hand, Yang Xiao condensed a black and white ball of light, and used the primordial extinction tactic.

Looking at the opportunity, Yang Xiao was thrown into Thunder Purgatory.

This Taichu Demon Extinguishing Technique was comprehended by Yuanshi Tianzun in the bookstore, and its power was not weak.

In the rumbling sound, the underworld creatures were submerged, and a scream of screams rang out.

Doing nothing and endlessly, Yang Xiao condensed and purified the ball of light with his left hand and exploded with light with his right hand, taking the opportunity to explode.

When the aftermath of the explosion subsided slightly, Yang Xiao displayed the Book of Seal.

There are so many bookstores that Yang Xiao doesn't know which one to use.

Dealing with a creature in the underworld whose strength is not as good as his is completely bullying.

When the book of seal fell, the creatures of the underworld had no resistance at all, and were directly bound firmly.

Yang Xiao grabbed it back and threw it to the system, then quickly hid his breath and left the place.

Just after Yang Xiao ran for a while, the previous powerful creatures in the underworld rushed back.

Finding that there was no companionship, several creatures in the underworld roared wildly, searching all around for a while, but they didn't find it.

After escaping all the way away from the place, Yang Xiao ran deep into the ruins while chatting with the system.

"System, did you ask anything?"

There was a long silence before the system spoke, and the tone was shocked.

"After asking, this underworld is another universe, not even weaker than our current universe."

"Under normal circumstances, the underworld will not be connected to our side, but under certain conditions, a passage will appear."

"What the specific conditions are, this underworld creature doesn't know."

Listening to the system's answer, Yang Xiao was shocked, it was really another universe.

But it's not right. If it's another universe, is it possible to fly there if you have the strength to cross the universe somewhere?

"It's not like that. Based on what I got, I deduced that in the underworld, it's actually one with our universe."

"How to put it, it is like the pros and cons. Normally, one side will always be maintained, but under certain conditions, the two can be connected, and even conversely, the other side dominates."

"Could it be that the so-called catastrophe is actually the invasion of the underworld?"

The system's tone was a little surprised and uncertain, and it gave out its guesses indefinitely.

Yang Xiao was dumbfounded for a while, let alone, the system might have such a guess.

Everything in the world grows relative to each other, this truth does not just happen in every world.

Maybe the universe they live in now really has a corresponding universe.

In comparison, the others are nothing, this is the real relative.

The yang world, the yin world, the yang world constantly consumes the aura in the universe, the balance is broken, and the yin world takes advantage of this opportunity to begin to rise.

If the Yang Realm can't survive this catastrophe, everything will be annihilated and return to chaos.

At that time, the underworld will occupy the universe and become the ruler of the universe.

Until the yang world that has returned to chaos gradually evolves and represses the yin world, the universe will be dominated by the yang world again.

The more Yang Xiao thought about it, the more shocked, the whole person was shocked and didn't know what to say.

There is such a big secret in this universe.

It is ridiculous that people living in this universe don't know this situation at all, they are still improving crazily, consuming the aura of the universe crazily.

Little did they know that the faster they consume, the faster the underworld creatures will emerge.

Suddenly, Yang Xiao thought of the fusion world of Hongmeng.

The more and more dense aura is definitely not coming out for no reason.

Rather, it absorbs and transforms from the universe, no wonder Hongmeng Avenue will say that catastrophe is about to occur.

The fusion of Hongmeng world swallowed so frantically, it will definitely absorb some auras that shouldn't be absorbed.

The spiritual qi in the universe definitely has a reason for their existence. Once the concentration drops to a certain level, the barrier between the yin and yang will disappear.

Before it was still a whirlpool, Yang Xiao felt that this catastrophe appeared in full bloom.

"The system, is it impossible to stop Hongmeng?"

Yang Xiao was silent for a while, guessing the secret of the universe, and he wanted to try to stop it one last time.

The system answered: "Well, if it could be stopped, Hongmeng Avenue would not say that at the time."

After listening to Yang Xiao, there was another silence, and he couldn't stop it!

Forget it, let's talk about the time when the time comes, not to mention there are still 10,000 years left.

"Unexpectedly, unexpectedly, unexpectedly, this universe turned out to be like this."

After thinking about it, Yang Xiao laughed and shook his head.

Suddenly, Yang Xiao came up with another thought. He felt that the universe he knew now might not be the full picture of the universe.

How big the universe really is is unknown, maybe he will have the opportunity to find out when his strength gets stronger and stronger.

It was mainly because Yang Xiao discovered that with his current strength, he couldn't even understand how crossing was.

He can use his strength to find people in the long river of time in some small worlds.

But when he asked him to go directly to a certain period of time in history, Yang Xiao found that he couldn't do it at all.

Yang Xiao asked about the system, and the system also said that even if it understands the power of time, it can't do it.

Even if the system can't surpass the power of the Great Domination, then what is going on when he passes through.

Yang Xiao has a feeling that things are not that simple.

Perhaps the system is not saying that it is not unreasonable. The westward journey of this universe and his future generations may not be the same place at all.

But if it is not a place, where is the earth he came from?

"Take a step, take a look, you will always understand, I want to see how I got there."

Perceiving Yang Xiao's thoughts, the system comforted.

Yang Xiao nodded silently. Of course he knew that he was not anxious. Even if he was anxious, it would not have any effect.
