After Liu Yu learned about the superspin civilization, he was ready to enter the small world first, you must know that the real world has passed for thousands of years, and 500,000 years have passed in the small world, that's right, Liu Yu adjusted the time flow rate of the small world again.

Now the real world is a small world for 500 years, Liu Yu has been in the real world for a thousand years, and 500,000 years have passed in the small world.

In these 500,000 years, because the entire small world belongs to the recovery period, the small world does not harvest many origins, and it adds up to 50 billion drops of world origin.

Five hundred billion drops of world origin seems like a lot, but for the development of hundreds of millions of stars. If the sky is reached, a good star system will be born.

However, Liu Yu came in to check the development of the small world, and the other was to check the water blue star.

After all, the good development of the Water Blue Star is related to whether the subsequent billions of stars can develop and provide a huge world origin for the expansion of the small world, which is one of the reasons why Liu Yu attaches importance to the Water Blue Star.

After Liu Yusi entered the small world, he checked the four worlds of the small world.

Among them, the population of the human race in the Monk Continent has basically not increased, while the population of the demon race has increased a lot.

Now the Monk Continent is a world where the demon race is respected, and the human race has become a professional race for the descendants of the demon race.

The decline of the human race has also led to a shortage of fresh blood in the heavenly realm, and now the population of the heavenly realm is only 100 billion, compared to the demon realm that rose later, the current population is still temporarily ahead, but in a few years the demon realm will become a stronger than the heavenly realm.

As for the current world of the undead, it is very powerful, after they slaughtered all beings from the four major forces, although they have declined some, but on the whole, they have always been much stronger than other worlds, and the current population of the world of the undead is many times stronger than the heavenly realm and the demon world, and it is worthy of the name of the most powerful world of the four worlds.

Therefore, the world of the dead will provide a large number of world origins for the small world every year, Liu Yu is still very optimistic about the world of the dead, otherwise Liu Yu, the four great powerhouses of the world of the dead, would not have been retained, of course, these four powerhouses have long since died, and they have been reincarnated again.

After Liu Yu looked at the four worlds, he came to the sky above the water blue star.

Aqua Blue Star has been developing for nearly a million years now.

It's been 500,000 years since Liu Yu last left.

From Liu Yu's doppelganger Heavenly Dao, I learned that after 100,000 years after Liu Yu left, the ape-man in the Water Blue Star had learned to use tools and make tools simply.

Among them, simple things such as stone knives, wooden spears, stone hammers, etc.

When Liu Yu left 150,000, these ape-men picked up animals that had been burned by fire from nature, and after finding that they tasted better than eating raw, they began to slowly preserve the fire.

Of course, these apes have also picked up animals that have been burned to death by nature's fires before.

It's just that any development needs to be a process.

They have evolved over thousands of years, from using tools to obtaining fire from nature, and preserving them.

By the time Liu Yu left the 200,000th year, the number of those ape-men had grown to nearly a million people in the entire Water Blue Star.

The population was large and they lived together, so they learned to drill wood to make fire in keeping the fire.

This is a major invention to drill wood for fire, and it can be regarded as a civilization if it can produce fire, and fire is also the source of civilization.

In the small world, after Liu Yu left the 300,000th year, the development of these ape-men became more colorful.

Not only do they know how to use tools, make tools, and produce flames, but they also learn to build from bird's nests, learn to make ceramics from fire pits, and learn to make fishing nets from aquatic plants in 100,000 years, which is a great progress, with a strong atmosphere of primitive civilization.

After 400,000 years, these ape-men formed tribes and had a strong sense of tribal belonging.

In this way, the tribal civilization of the apes has developed until 100,000 years, and in the last 100,000 years, their progress has been great.

Because of the war

In the 500,000th year, the last 100,000 years, they invented writing and timekeeping.

If the appearance of fire is a sign of primitive civilization, then the emergence of writing is an effective inheritance of a civilization, and a civilization with inheritance is a real civilization.

Of course, the ape-men at this time should not be primitive ape-men, they do not have the deep body hair of ape-men hundreds of thousands of years ago.

In particular, after they developed words, tools, tinder, and warm animal skin clothes, the body hair on their bodies has disappeared after more than 100,000 years of world evolution, and it is not much different from the humans on the real earth.

Until Liu Yu entered the Water Blue Star, these tribal civilizations were still prosperous, and this was a tribal civilization that had developed to the peak.

In fact, it is no different from a vassal state.

It's just that there has never been a strong tribe capable of unifying one side and forming an advanced management system.

The current tribal civilization has also formed various privileged classes, only if there are powerful tribes around, they will defeat them, plunder a large number of people, and then let them develop slowly.

In any case, these tribal leaders are unwilling to break the current class system.

Without the class system, their privileges would disappear, everything about them would disappear, and they knew very well that whoever dared to break this class system would be the enemy of the whole world.

How to say it, Liu Yu doesn't like this kind of civilization system, but he just wants to see a different development of civilization, and he is very entangled in whether to change their development trajectory.

Liu Yu thought about it for a long time, and finally decided not to directly participate in it himself, but to use the doppelganger Heavenly Dao to do these things, this should be regarded as the world's self-regulation, right?

Generally speaking, the world is nothing more than volcanic eruptions, ice worlds, floods, droughts, these are all things that belong to nature.

In the end, Liu Yu turned around and used floods, which was also the best choice.

After all, the Ice Age will destroy a lot of ecology, which is not conducive to the future development of the world.

The same is true for droughts, and the same is true for volcanoes.

The best thing is the flood, they can not only destroy those tribes, but also disperse the entire population of the tribes, and those high-level ones will naturally be eliminated by nature.

So Liu Yu took over the management of the doppelganger Heavenly Dao.

At the first thought, the sky and the earth suddenly changed, lightning and thunder, and the sky began to rain heavily.

The rain lasted for more than a month, and the whole world became a world of water.

Countless terrestrial creatures were drowned, and the pattern of tribal civilization was completely destroyed.

After doing these things, Liu Yu smiled~

This is self-regulation by nature, and it cannot be regarded as human interference.

PS: In a busy schedule, it's not easy to update, it used to be a chapter at twelve o'clock at noon, a chapter at seven o'clock in the evening, there is really no time these days, the update is very unfixed, I hope you forgive me.

Ahem, cough cough, don't keep everyone's recommendation tickets, after all, don't you need money for recommendation tickets?

By the way, there is also a commuter pass!

In PS: Now the cumulative reward is 48 yuan, and the monthly pass is 72 chapters, and these two will add a chapter to any one hundred.
