Chapter 1899: The Trisolaran Galaxy
Liu Xu listened to some cultivators' complaints about the planet, and with his information advantage as the lord of the world, Liu Xu understood the reason for the planet's explosion.

Just like what the monk said, one star cannot take care of so many planets.

For the Great Heaven World, there are always only two restrictions on promotion. One is the size and area of ​​one's own world, and the other is the degree of control over the laws.

Thanks to many innate treasures, Liu Xu has almost mastered the laws, and at most he has to deal with the details of individual laws. However, the expansion of his own world is still a huge problem.

At this time, the largest world in Liu Xu's hands was still the Qin and Han World, so after the Qin and Han World became the Zhongtian World, Liu Xu still relied on continuously adding planets to the solar system to expand the area of ​​the Qin and Han World.

Liu Xu's original idea was to continue creating planets, and when the number of planets was large enough, he would be able to reach the level of the Lord of the Great Heavenly World.

But judging from the current reality, nothing is optimistic.

At this time, Liu Xu had already stuffed 100 planets into the entire solar system. Before, Liu Xu would stuff planets into the orbit between the earth and the sun, and then adjust the orbital data of each planet to achieve a complete galaxy.

Theoretically, the space between the Earth and the solar system alone can accommodate more than 10,000 Earths.

But the reality is that there is a strong interaction between each planet, and once the number of planets increases, it will no longer be possible to maintain a stable orbit, so after the initial few planets are crammed in, the remaining planets can only be placed in more distant locations.

By the time Liu Xu had packed up the 100th planet, the planet's daily maximum temperature was only 10 degrees, which was obviously not suitable for human survival. However, some special technological modifications could be used to make this planet suitable for human survival!

That’s what Liu Xu originally thought.

But now it seems that this is a complete mistake. The solar system cannot bear the 100th planet, so the 100th planet exploded directly. And the other 99 planets are not stable either. Liu Xu observed the status of these planets and found that many of them are between exploding and not exploding.

As a result, all kinds of natural disasters occurred frequently, and even Liu Xu, the master of the world, could not stop them. The maximum number of planets that the solar system could withstand was only within thirty. If there were more than thirty, everything would fall into a highly unstable state.

Moreover, Liu Xu had a feeling that continuously expanding the solar system like he was doing would not allow the Qin and Han world to break through to the Great Heaven world, because the limit of the solar system was a Middle Heaven world. If he wanted to break through to the Great Heaven, he must have a system higher than the solar system!

"A system higher than the solar system? Are you asking me to create a galaxy?" Liu Xu muttered, and then in an instant, his Tao heart vibrated wildly, and his whole body felt a kind of pleasure of sublimation!

"Oh no, I'm not really going to create a galaxy!" Liu Xu showed an expression that was uglier than crying.

Congratulations to Liu Xu. He successfully found a way to allow the Qin and Han world to continue to break through. It’s just that Liu Xu doesn’t like this path very much. But the road is in front of him, so Liu Xu has no choice but to move forward.

So Liu Xu began to move forward, heading towards the edge of the solar system.

Observing the universe from the earth, we can see countless stars, and each star is actually a shining star. Moreover, the light of most stars cannot reach the earth, and only the brightest stars can be seen.

The Earth is located in the Milky Way, and the Milky Way has 1 billion to 000 billion star systems like the solar system. These are the results of hundreds of years of observation by humans on Earth. However, for humans on this Earth, all of this is Truman's world. When Liu Xu really walked to the edge of the solar system, he felt a strong stream of chaotic air. These chaotic air currents rotated at high speed and eventually formed a huge wall, blocking everything in the solar system within the wall.

This wall can also be called an air wall, but it is an air wall that surrounds the entire earth and is located in the universe.

The air wall is different from the world barrier. The world barrier is something that can only be observed at the rule level, while the air wall is something that can be sensed by the mortal body. Liu Xu also knew that about a dozen years ago, a cultivator from Earth drove a spaceship to the air wall and then directly crashed into the air wall. The entire spaceship and the cultivator on it naturally ceased to exist.

These air walls are so strong that they can even block incoming physical bodies.

Fortunately, Liu Xu is the master of the world, so he stretched out his hands and tore the entire air wall into two halves, revealing the world barrier behind the air wall. This is the upper limit of Liu Xu's Qin and Han world.

"Open it for me!" Liu Xu roared, and the entire world barrier was pulled open by Liu Xu, the lord of the world himself, revealing the void outside the world and forming an entrance between the world and the void.

However, this was not enough for Liu Xu.

He waved his hand to disperse the air wall and took another step forward. This step was equivalent to the distance of almost the entire solar system. As Liu Xu took a step forward, the edges of the world barrier and air wall that had been torn apart began to grow wildly, spreading outward rapidly and without limit.

With every step Liu Xu took forward, the edge of the entire world barrier expanded outward madly.

The diameter of the entire solar system is 3000 billion kilometers, or 0.003 light years. Liu Xu moved forward step by step, a total of 1400 steps forward, and the entire world barrier expanded by a diameter equivalent to 1400 solar system diameters.

By the time he finished these 1400 steps, Liu Xu's face had turned pale and he was sweating profusely. He used up the last of his strength to merge the world barriers again and close his own Qin and Han world again.

If he walked normally in the void, 1400 steps would only take Liu Xu a few minutes, and it was a completely insignificant distance in the void. But if the barrier of the entire world was expanded to this extent, it would undoubtedly almost kill Liu Xu.

At this time, the world power of the twenty-fourth heaven was almost completely dried up and no longer existed.

Liu Xu's previous battle with the Lord of the Holy and Beautiful World only consumed 30% of his world power. This wave of expansion consumed nearly 50% of his world power. Only 20% of the world power in Liu Xu's body remained.

This is because the expanded part is completely void and does not involve any planets or populations. The pressure on the world barrier is actually not that great. The pressure that the entire world barrier needs to withstand has only expanded to about 20 times the original. Otherwise, Liu Xu would have been completely drained of all the world's power and there would be no way he could have arrived here.

Logically speaking, if it weren't for the great contribution of the fake Liu Xu, which increased Liu Xu's world power limit and recovery speed by more than four times, Liu Xu would never dare to do this and expand his own world from the solar system to the Proxima Centauri galaxy!

The Proxima Galaxy is located in the constellation Centaurus and has a system of three stars orbiting it. It is also the galaxy where the Trisolarans are located in a certain novel!

In addition, if we only talk about the world barrier at this time, Liu Xu's world barrier is already the largest world barrier in the void, even incomparable to the Lord of the Perfect World.
