Time flies by like a white horse, fleeting. Before you know it, one hundred and fifty years have passed.

In the past 150 years, the whole world has undergone earth-shaking changes.

First of all, the emperors of all countries finally decided to give up most of the full strength in their hands.

Reformed into a constitutional monarchy.

The emperors of all countries will be honorary leaders in the future.

The real ruler is the president or president of each country.

The president, or the president, is elected through elections.

It can be said that the president of flowing water is the emperor of iron.

The emperors of various countries seem to have lost their power, but their orthodox status is actually more stable.

Because, if the world is a family, I am afraid that it will not take a few generations, and there will be unscrupulous descendants.

It is very likely that it will make people angry and resentful, and thus lose the country.

The constitutional monarchy, on the other hand, avoids this kind of thing to the greatest extent.

In the past 150 years, the emperors of various countries have changed for several generations.

And the president, I don't know how many realms have changed.

However, the city of flowers has always been the center of science and technology in the world.

Because over the years, the Holy Emperor Li Su has been guiding the continuous progress of science and technology.

Yes, Li Su was revered as the Holy Emperor.

One hundred and fifty years later, the Holy Emperor, who was nearly two hundred years old, was still in middle age.

For more than 150 years, several prophecies have been fulfilled in a book of warnings.

Now, the Holy Emperor has become a god-like being.

Nearly 200 years old!

In the whole world, it is a unique existence.

In fact, Li Su was also very lonely at this time.

Because his longevity is actually accomplished through the system.

But this function does not work on other people.

Including his queens and princesses, and his children, not good.

His queen and princess, his children, and his brothers who fought with him.

These people are all gone.

He was the only one left.

So, Li Su is really bored and lonely.

And after so many years of accumulation, the loser value of the system has accumulated to an extremely terrifying point.

Under boredom, Li Su began crazy scientific research.

Eventually, Li Su developed the Pangu spacecraft.

Recently, Li Su has decided to explore Mars.

The environment of Mars, as early as a few decades ago, Li Su used special testers to explore.

And also succeeded in discovering liquid water on Mars.

Next, Li Yu successfully sowed some microorganisms and seeds of some plants on the surface of the water and the shore.

After decades of development, it has grown into an oasis.

A small ecological environment has been formed.

Moreover, these ecological environments are gradually spreading outward.

After that, Li Su continued to bring some adaptable animals and plants to Mars.

This also makes the ecological development on Mars more and more like Earth.

And this time, Li Su decided to drive a spaceship and go directly to Mars for a exploration.

And this time, Li Su also decided to go to Mars this time for a global live broadcast.

Now, because of the warning book, the world attaches great importance to environmental protection, and attaches great importance to environmental protection.

The whole country is working hard to develop aerospace science and technology.

Technological progress is rapid.

But there is still a long way to go to Mars.

However, at this time, the Holy Emperor Li Su actually developed a spaceship that could land on Mars.

This news shocked the whole world.

Next, the live stream begins.

Li Su boarded the spaceship and started directly.

The spaceship, soon at a very fast speed, took off into the air.

Next, the perspective of the live broadcast came to the outside of the spaceship.

Countless viewers around the world have seen that the earth is getting smaller and smaller in the sight of the spacecraft.

Soon, the spacecraft flew out of the atmosphere.

The Earth is getting smaller again.

It's a very unique and strange feeling.

The distance between the Earth and Mars is subject to change.

And the distance chosen by Li Su is a relatively short distance.

It's about 60 million kilometers.

Navigating in space, from the perspective of a spaceship, is a very peculiar thing.

The speed of the spaceship built by Li Su reached a very astonishing speed.

After only half a month, he came to Mars.

Then it entered the orbit of Mars, and after half a circle of orbit, it finally landed slowly.

After coming to Mars, Li Su put on a spacesuit, stepped out of the spaceship, and stepped into Mars.

Then, after some testing, Li Su found that the environment on Mars.

A small amount of oxygen has been produced, but not enough for humans to survive.

However, the environment here, wearing a spacesuit and equipped with a device to produce oxygen, can still do some research.

In advance, it is necessary to conduct a detailed scientific study of the environment here.

Then make the environment here more suitable for human habitation, and then start gradual migration.

Before that, Li Su decided to build some research institutes first.

Next, Li Su started the spaceship.

Then, with the robot, he directly found a suitable location, built a house, and built a research institute.

Next, Li Su called the spaceship and left.

After returning to Earth, he took a group of scientists to Mars to continue exploration.

A year later, on Mars, a new energy source was discovered.

Using this energy source, the speed of the spacecraft can be propelled tenfold.

In the solar system, it is already possible to go to more planets.

I believe that it will not be long before the earth civilization will be able to enter the first-level cosmic civilization.

These scientists, after spending a month on Mars, need to return to Earth to carry out various tests and recuperation.

But overall, there are no serious sequelae.

This is enough to prove that after continuous improvement, Mars will become another place suitable for human habitation.

The environment on Mars is very different from that on Earth.

This requires scientists to conduct constant experiments.

The environment of Mars also needs to be guided and improved.

In a few years, the environment of Mars will become suitable for human development.

Eventually, humans will colonize Mars.

……

Fifty years later, humans have begun to migrate to Mars on a small scale.

This time, the immigrants are still dominated by scientific researchers.

At this time, the environment of Mars is still relatively harsh, but it is barely able to allow human beings to survive.

There is also officially life born on Mars.

And the detection ability of human beings is also gradually increasing.

Humans can easily reach any planet in the solar system.

The earth civilization has officially entered the first-level cosmic civilization.

And at this moment, the loser subsystem carried by Li Su, after being silent for more than 200 years, suddenly issued a prompt again:

When you discover the Immortal Cultivation Civilization, please ask the host if you have decided to go there.

This time, you need to spend 100 million losers!

Cultivating immortal civilization?

Looking at the remaining trillions of losers in the loser subsystem, Li Yu said decisively: "Go to the Immortal Cultivation Civilization!" ”

All-book-end!

This book, written for more than a year, is now over.

Very complicated feelings, after finishing this testimonial, I'll send it again in the future!

Welcome everyone to move to Yanyu's new book "Datang One Knife 999 Level"
