With Zhang Yu's strength, no subtle changes could be hidden from his senses. However, he was sure that there was no change in the empty space outside the Legend of the Condor Heroes!

"This is strange." Zhang Yu frowned. The situation in the Legend of the Condor Heroes is obviously different from that in several worlds such as the Covering World.

The empty space outside the world of the sky is always decreasing at a constant speed, the same is true for the fight breaking world, the fairy sword world, and the world of demon subduing the West.

Only the empty space outside the Legend of the Condor Heroes has never changed.

What exactly causes it?

How is the world of The Legend of the Condor Heroes different from the rest of the world?

Zhang Yu fell into deep thought.

In essence, the Legend of the Condor Heroes is no different from the World of Covering the Sky, the World of Fighting Break, etc., but the level is relatively low.

"The only difference is that the Legend of the Condor Heroes is still a primitive world, without the intervention of external forces." Zhang Yu thought for a long time before he thought of this possibility. "Does it be necessary to have external forces to help the Legend of the Condor Heroes grow so that the empty space around the Legend of the Condor Heroes can be reduced?"

Apart from this possibility, Zhang Yu really couldn't think of any other reason.

Just when Zhang Yu thought he had found the truth, the void space in his sight changed without warning.

I saw that the void space outside the Legend of the Condor Heroes quickly shrank at a speed visible to the naked eye, and it stopped changing until it narrowed to a certain level.

What's going on?

Zhang Yu's eyes were immediately attracted by the void space, but he stared at the latter for a long time, but he did not notice any movement anymore.

After passing through the void space and returning to the The Legend of the Condor Heroes, Zhang Yu carefully checked the situation in the Sagittarius world, but found that everything was very normal and there was no abnormal situation in the Sagittarius world. But, the void space was indeed reduced. Zhang Yu was sure of this, it was definitely not his own illusion.

The world of The Legend of the Condor Heroes has not changed, which proves that the reduction in the empty space outside the Legend of the Condor Heroes has nothing to do with the Legend of the Condor Heroes, but is caused by some other special reason.

Zhang Yu passed through the void space again and came to the turbulent flow of time and space.

The eyes were still extremely magnificent, shocking and dazzling.

Zhang Yu vaguely felt that there was no change in the turbulent flow in this time and space. In other words, even if there was any change in the turbulent flow in the time and space, it would be difficult for him to notice because his spiritual thoughts were too small, and he could not even cover one billionth of the turbulent flow in the time and space. How could he understand the situation of the entire turbulent flow in the time and space?

The reason why Zhang Yu believes that the reduction of the void space outside the Legend of the Condor Heroes has nothing to do with the turbulence of time and space is because there is no abnormal change in the turbulence of time and space around this void space.

"The shrinking of the void space has nothing to do with the turbulence of time and space, nor with the The Legend of the Condor Heroes." Zhang Yu frowned and became more and more confused, "So, what exactly causes the shrinking of the void space?"

After pondering for a while, Zhang Yu still couldn't find the answer and couldn't help but murmur: "It seems that we can only wait until the world of Tianlong Badi is formed and then see if there is such a situation in Tianlong Badi..."

When talking about the world of the Tianlong Ba Tribe, Zhang Yu immediately checked the current formation progress of the former.

But when he saw the whirlpool of the world, he couldn't help but be stunned: "Has it formed?"

Before we knew it, the world of the Dragon and Eight Tribes has taken shape!

"Wait, when did the world of Tianlong Ba tribes take shape?" Zhang Yu suddenly thought of the changes in the void space outside the Legend of the Condor Heroes. Will there be any special connection between the two?

Although the World of the Heavenly Dragon Bashu and the Legend of the Condor Heroes are two independent worlds and have no substantial connection, why is it so coincidental that the world of the Heavenly Dragon Bashu was just taking shape when the empty space outside the Legend of the Condor Heroes reduced?

For no reason, Zhang Yu remembered what the system said at the beginning: creating a world or upgrading a world is the process of unsealing the seal and enhancing the will of the world. Isn’t this situation just confirming the system’s words?

However, what is the truth of the matter still needs further verification.

"Actually, the verification method is very simple." Zhang Yu looked at the Lu Xiaofeng world with a formation progress of about 55%. As long as he always pays attention to the Lu Xiaofeng world, when it is formed, he can check whether the virtual space outside the The Legend of the Condor Heroes world is reduced, he can verify the relationship between the two.

One may be a coincidence, but two times can’t be a coincidence?

In this way, Zhang Yu sat cross-legged in the turbulent flow of time and space, patiently watching Lu Xiaofeng's world take shape bit by bit, and watching the blurry projection gradually become clear. Although it was a little boring, Zhang Yu could still accept this boring compared to cultivation.

Time passed slowly, and I don’t know how long it had passed. When Zhang Yu felt his eyes were a little dry, Lu Xiaofeng’s world was finally about to take shape. The projection was extremely clear, just like a real world, but without color, giving people a feeling of loneliness and silence.

At this moment, Zhang Yu finally shifted his gaze, staring at the empty space in front of him, and silently calculating time in his heart.

"Ten, nine, eight, seven..." Zhang Yu's breathing was a little tight, and he became a little nervous inexplicably, staring at the empty space without blinking.

When the number that Zhang Yu silently recited reached "one", the empty space in front of him suddenly changed.

The same scene as the scene Zhang Yu saw before, the void space at this moment also quickly reduced at a speed visible to the naked eye. With just one breath, it reduced a lot. However, after one breath, the void space stopped again, maintaining a fixed area or volume that does not change anymore.

really!

Zhang Yu was excited, exactly as he guessed. When a new world was born, the empty space outside the original world would be reduced, and time was almost at the same time.

By this time, Zhang Yu could basically draw a conclusion that incubating a new world can indeed reduce the area or volume of the empty space.

Every new world is born, and the void space in the old world can be reduced. If the number of new worlds reaches a certain number, the void space will eventually disappear completely!

"So, I've taken the right path to create a new world!" Zhang Yu couldn't help but laugh. Although he was a mistake and created a new world for other purposes, now it seems that this path is exactly the most correct path.

He didn't know why the birth of the new world reduced the space of nothingness, and he didn't need to go to the bottom of it. He just needed to know that doing so would be beneficial to him.

"Advance the original world and the creation of a new world can help reduce the scope of the virtual space and enhance the will of the world..." Zhang Yu roughly understood how to reduce the virtual space, "However, the former can only affect the virtual space outside the world, while the latter can affect all worlds!"

In order to confirm this, Zhang Yu went to the world of Zhatian.

Passing through the void space and coming to the turbulent temporal and space outside the world of the sky, as Zhang Yu expected, the void space here has been reduced a lot compared to when he left before, and it is much more than the area it should have been reduced. This is obviously a benefit brought by the birth of the new world.

Afterwards, Zhang Yu went back and forth to fight back and forth, the World of Fairy Sword, the World of Demon Subduing World, the World of Sky, and other worlds, observing the void space outside these worlds, and the changes in the void space in these worlds even verified his guess.

At this moment, Zhang Yu finally understood the truth and mystery of the changes in the void space.

"Although I can't study the void space thoroughly, I know how to reduce the range of void space. For me, this is enough." Zhang Yu smiled, feeling very comfortable. He spent so long and tossing around in various worlds. Now he finally has an insight into the truth. All the hard work and sweat are worth it.

After a while, Zhang Yu left the turbulent flow of time and space, and returned to the sky realm through the empty space.

He landed on Baoshan, sat next to the spiritual spring on the hillside, thinking about his next plan.

Since you know that incubating a new world can reduce the empty space, and know that the advancement of the world can reduce the empty space, you should make good use of it. Otherwise, it would be in vain if he worked hard to find out the truth?

"Perhaps, you can incubate some low-level worlds appropriately!" Zhang Yu originally didn't care much about the low-level world, but now, he has greatly increased his attention to the low-level world. What he cares about is not the low-level world itself, but the birth of the low-level world and its impact on the empty space outside the original world. In this regard, the value of the low-level world is no less than that of the high-level world.

To incubate a low-level world, this is very simple. Zhang Yu only needs to use the trick of bewitching, use many stories as the basis and compile some historical books.

But it is not easy to advance the original world!

Think about the wilderness world, how many billions of years have been spent since its birth?

However, even so, it was with the help of Zhang Yu that he successfully advanced to the seventh-level world. Otherwise, he would have to endure tens of thousands or even hundreds of thousands of years...

Think about it, the world of the sky was repaired for thousands of years, and the immortal realm had only barely repaired a little bit. It was not until Zhang Yu personally took action and pulled the god of celestial wolf and others as coolies. After several months of hard work, he advanced to the top seventh-level world.

The World of Fighting Break, the World of Fairy Sword, the World of Journey to the West, etc. do not have the conditions to directly advance, and it is even more difficult to advance...

"Only by advancing can we significantly reduce the scope of the empty space. Otherwise, if the little changes, the terrazzo will pass through, we have to wait until the year of the monkey and the month of the horse?" Zhang Yu had seen the scene of the rapid reduction of the empty space outside the old world when the new world was born, and naturally he was not satisfied with the little reduction and change. "But, what should we do to advance the various worlds?"

Although Zhang Yu has some experience in this regard, he doesn’t know much.

He only knew that introducing a new cultivation system and perfecting the laws of heaven would be of great help to the advancement of the world. At that time, the Wilderness World obtained the opportunity to advance because of the introduction of the cultivation system of the World that Covered the Sky. The key is that the Wilderness World itself is on the verge of advancement, and all it lacks is a shortcut. The Fighting World, the Immortal Sword World, etc. are still a bit far from advancing!

Therefore, the introduction of a new cultivation system alone has a very weak impact on the entire heavenly way. At least a hundred flowers must bloom, tens of thousands of cultivation systems must be introduced, and even these cultivation systems must be rooted in order to help a seventh-level world advance.

"This task is impossible to accomplish by me alone." Zhang Yu shook his head, "Even if everyone in the Cangqiong Academy is sent out, it will be difficult to complete." Such a thing is difficult to complete by just one person or one force, and it is like a drop in the bucket.

A low-level world like the World of the Heavenly Dragon and the Eight Parties and the Legend of the Condor Heroes may not be difficult, but a seventh-level world like the World of Fighting Break is difficult as if it is ascending to the sky.

What should I do?

Zhang Yu's brows frowned deeply.
