Stars (solar system), galaxies (flood rivers), star fields (Milky Way), and cosmic galaxies are diverging from small to large.

The distance from Aquarius to the Flood Galaxy is about 2,000 light years, and even Liu Yu in the Mahayana period will probably take more than 400 years to reach it, which is a long interstellar journey.

Of course, in these four hundred years, the small world is also constantly developing, and in reality, four hundred years, the small world is about two million years, in such a long time, Liu Yu will obtain a large number of origins, and the strength is estimated to improve by one or two big realms, that is, to actually reach the flood galaxy system, Liu Yu may reach it in close to two hundred years.

Ten years after Liu Yu's interstellar shuttle, fifty thousand years have passed in the small world, and the heavenly realm has also become prosperous again with the addition of the Nether Ascendant.

Since the undead world did not suffer much loss, the recovery speed was a little faster than that of the Celestial Realm, but as time passed, the number of celestial powerhouses slowly surpassed that of the Undead World.

Although the world of the undead also has ascended people to replenish, there are only a few cultivators who cultivate this death-type system.

In the new 200,000 years of the small world, the whole world flourished again, and it was also the golden age of cultivation.

Now the entire Savage Continent, the Heavenly Realm, and the Undead World have also provided Liu Yu with one million drops of origin every month, that is to say, during this time, Liu Yu has obtained two hundred billion drops of origin, which also makes Liu Yu's strength reach a new height, surpassing the strength of the Mahayana period.

Since the strongest person in the small world heavenly realm is now the peak powerhouse of the Tribulation, they have not set the name of the next cultivation level system, and Liu Yu can only define a strength realm "River System Realm" for himself according to his ability to cross the galaxy system, the river system powerhouse.

Liu Yu at the river level is undoubtedly powerful, and he has the same idea as the middle two at that time, that is, the strength of a slap can destroy tens of thousands of space warships.

It is naturally a bit nonsense to destroy so many warships with one slap, but it is still possible to crack a planet like Earth with one punch.

Such a powerful strength also made Liu Yu happy and shocked, it is not a matter that the creatures in this small world are too powerful, when the time comes, there will be so many strong people who have crossed the robbery, and even the strong people of the Mahayana period who have fought, wouldn't it really be able to destroy the world?

This made Liu Yu have to stop and continue to shuttle through the starry sky.

That is, to limit the strong in the small world, the strongest cannot exceed the strength of the Dacheng period.

In the hundreds of thousands of years of development of the small world, the small world has also become more perfect, thus giving birth to the powerful mysterious system of the law of time.

Normally, time is just a definition, a metaphor, but this mysterious system was born in the small world.

It can be said that the time system of the small world was not born now, it existed when the small world was just born, but now that this time system has been regularized, Liu Yu can use the origin to override the time flow rate of the small world, and its scope of influence is the entire small world.

Of course, in the real world, Liu Yu didn't even grasp the rules, let alone something as tall as time.

However, the power of the origin in Liu Yu's body is very powerful, and it can simulate the release of the energy of various systems.

In order to limit the number of strong people in the small world, and how much strength the strongest is, it is not only necessary to regulate the flow of time in the heavenly realm, but also to control the distribution of the essence and spirit of the dead creatures in the heavenly realm at all times.

So Liu Yu adjusted the speed of time in the heavenly realm to the proportion of one day in the real world and one year in the heavenly realm.

In this way, not only will the speed of the birth of the strong be slowed down, but it can also increase the number of people in the heavenly realm, and once the population is large, the aura of the heavenly realm will be greatly reduced, and the probability of the birth of a strong person in the heavenly realm will be invisibly controlled.

There is also a monk in the Heavenly Realm who also needs to cross the tribulation now, for example, breaking through to the out-of-body strength needs to cross the five or nine heavenly tribulations, the kind that does not exist in a hundred, in this way, the small world can not only obtain a large number of origins, but also control the population of the Heavenly Realm to be full.

After the death of a celestial creature, the distribution of its essence and spirit has also changed from three layers to one layer, and in the future, the wild continent and the celestial realm of the small world, the world of the undead, before the galaxies in the crystal wall system are not conceived, basically will not be large, and some are just a layer of essence and spirit turned into aura, providing small world monks to cultivate.

Among them, the sun in the small world is also an energy converter, and after the various rays emitted by the sun are absorbed by the plants, the plants are spitting out aura, which is also the reason why Liu Yu is not worried about the depletion of the aura in the air in the small world.

Liu Yu at the primary level of the river system is very fast, and can reach one million kilometers per second and 60 million kilometers per minute, while it takes about () time to reach the flood galaxy system (about 2000 trillion kilometers in 2000 light years).

Liu Yu sorted out his mentality again, stepped into the dark universe, and headed towards the Flood Star Galaxy.

Liu Yu has been lurking in the Flood Galaxy for a year.

The Flood Galaxy is a galaxy of more than 200,000 stars.

There are two major genetic system civilizations in the flood galaxy system, which are the natural gene civilization and the drug gene civilization.

These two major genetic civilization systems were both scientific and technological civilizations at the beginning, because genetic research is a system born from science and technology. However, these two major systems of civilization are mainly based on the gene system, supplemented by the scientific and technological system.

Because a strong genetic powerhouse can not only prolong lifespan, but also can exert the ability of several space warships after wearing a mecha, so this is an era of a strong gene, and it is also an era of mecha crisscrossing the universe.

Whether it is a mecha or a genetic powerhouse, they have made countless people yearn for it.

The space battleship is a weapon operated by ordinary soldiers, and the attack power of the space battleship in this era is indeed better than that of the mecha, but due to scientific and technological reasons, the flexibility of the space battleship is much worse than that of the mecha assault team composed of the genetic strong, so the country and the ordinary people attach great importance to the mecha, which also leads to the reason why the genetic mecha strong is desirable.

Of course, after the space battleship is scaled, there is no genetic mecha warrior, but how can a small floodlight galaxy have so many resources to build a battleship?

Its main reason is nothing more than resources, and technological reasons have led to the rise of genetic mecha warriors.

Of course, the development of any system to the peak is very powerful.

For example, because of his identity, Liu Yu acted as an old grandfather and taught a young man with natural system genes.

Natural system genes, to put it bluntly, are constantly exercising, and when the body reaches the limit, it will awaken all kinds of genetic abilities.

Genetic abilities are divided into two categories, power systems and energy systems, such as mastery, wind, electricity, water, and fire, which are all energy systems.

And the power system is much simpler, the body metalization, and berserk are all power systems, and the genetic cultivators of the power system are mainly exercising the body, training the body to the point of being extremely hard, of course, the power system is not without energy.

Among them, genetic energy, whether it is a genetic warrior of the energy system or a genetic warrior of the power system, the first step of their awakening is genetic energy.

And their physical attributes determine which system is best for them to follow.

Professor Liu Yu's young man is called "Yu Xuan".
