Technological supremacy starts with acquiring alien spaceships

A week later, Chen Yu's two new level 3.5 civilization Home-class motherships successfully arrived in Earth's near orbit.

Chen Yu stood in the command room, looking at the familiar blue planet.

This trip out was another two years, and he wondered what the situation on Earth was now.

It had been several years since the solar crisis was discovered.

'Brain, open the solar detection activity data for the past year.'

[Okay, Captain.]

The holographic screen in front of Chen Yu displayed dense detection data.

'Brain, interpret this data.'

[Captain, according to the solar activity data for the past year, the sun's activity has been 1.03 times stronger than it was 5 years ago. If it continues at this rate, the sun will reach the critical point of human tolerance in 13 years.]

[Currently, worldwide, except within Yanxia, the number of people suffering from skin cancer in various countries has increased by 20% per year in the last 5 years, and the number of deaths is increasing year by year.]

Chen Yu thought that Yanxia had high-tech medical pods that could cure even cancer patients.

But if, in more than a dozen years, the solar radiation became so great that humans could not withstand it.

Even the medical pods would be useless.

Moreover, scientists once predicted that there were still 30 years left, but now, less than 10 years have passed since the discovery of the solar crisis.

Now there are only 13 years left, proving that solar activity is becoming more intense.

It's possible that 13 years is a conservative estimate, and there may even be only a few years left.

Chen Yu's underground migration plan, it seems, should be gradually implemented.

It's possible that he only has a few years left.

Currently, Yanxia's underground shelters have been built for more than half of the country, and huge shelters have been built underground in various large cities.

Now it is just the improvement of some facilities, and the underground通道 connecting the major shelter bases are still under construction.

According to the brain's assessment of the current construction progress, Yanxia will be given about 3 more years.

About 100 underground super shelters will be built across the country.

Each city, with a little crowding, will accommodate 10 million to 15 million people.

Yanxia currently has 1.4 billion people, and 100 super underground cities can accommodate up to 1.5 billion people.

Which means that all the people of Yanxia can be protected.

Looking at the world, the North American Universal Colony.

Out of humanitarianism, Chen Yu improved the 10 underground shelters previously built by the United States.

It can accommodate up to 80 million to 100 million people.

Which means that 250 million people in the Universal Colony will be abandoned when the solar crisis truly arrives.

Chen Yu plans to implement a contribution system in the Universal Colony.

In the next 5 years, the former American people there.

They will have to compete for places in the underground shelters according to their contribution.

Their total population is 330 million, which means that only about 100 million can survive.

The survival ratio is about 3 to 1, and in the Universal Colony.

Those former American drug addicts, and those with thick skins who have committed 0-yuan purchases, will be abandoned in the future.

To enter the underground shelter, you must have good character and no serious criminal record.

As for other countries in the world, such as Europe, they are building underground shelters almost at the same time as Yanxia.

Plus, they originally have a small population, and basically more than 80% of the people can survive.

And those third world countries in Africa are miserable, but after Chen Yu became the Earth's leader.

Out of humanitarianism, he also built 5 underground shelters in Africa, which can accommodate about 50 million people.

And Africa's total population is as high as 1.4 billion, but this world is inherently unfair.

Most of them will disappear from this world when the future crisis arrives.

As for some countries in Asia, they basically have one or two shelter bases.

As for India, the country with the largest population in the world, their leaders were slow to realize, and the country with billions of people.

So far, less than 5 shelters have been built, and the construction progress is extremely slow.

In order for all mankind to continue, Chen Yu contributed the necessary circulation system for underground shelters to all countries.

He provided two controlled nuclear fusion engines for each of their shelters.

Chen Yu has done his best to do this.

Chen Yu parked two Universal-class Home motherships in near-Earth orbit.

He himself returned to Earth on the No. 1 mothership.

Knowing that Chen Yu was back, the leaders of various countries came to welcome him.

And when Chen Yu returned home, his sister, mother, and father surrounded him and his four daughters-in-law.

The mother walked around the four wives a few times, wanting to see if anyone's belly had grown bigger.

But none of them did.

"Xiaoyu, you've been out for more than two years, you must have played a lot of poker with my daughters-in-law at night, why haven't I seen anyone with a big belly?"

Chen Yu was embarrassed, he had taken precautions, and for him now, there were still many things to be completed, and having children was an unwise choice.

Moreover, his family now has a long lifespan, and it's the same to have children later.

Otherwise, when the children are born and grow up, their parents will look almost as young as them.

"Mom, don't rush us, you two can live for more than a hundred years, you'll definitely have great-grandchildren in the future."

Sister Chen Jia brought her three male lovers, all top domestic male stars, Xiao Zhan, Wang Yibo, and Wang Hedi.

"Brother, these are my three husbands, awesome, right!"

Chen Yu was speechless!

"Old sister, you really found three men? Aren't you afraid that Mom and Dad will beat you up!"

When Chen Yu saw the three handsome male stars serving tea and water to the elders, being extremely attentive.

He finally understood how his sister had persuaded his parents.

In the following days, Chen Yu will be on Earth, completing a comprehensive upgrade of his tens of thousands of level 3.5 civilization attack ships.

Let them become level 4 civilization attack ships.

All the previously equipped laser weapons were eliminated, and Chen Yu was in the level 4 civilization technology library.

He obtained a technology that uses existing metals on Earth for deep refining.

It can increase the hardness of the metal dozens of times, close to the shell hardness of the Kunster attack ship.

At least it can resist several shots of level 3.5 civilization laser cannons, and it can also resist one shot of level 4 civilization laser weapons.

Because Chen Yu's number of attack ships is currently about 50,000.

A comprehensive upgrade is a long time, plus refining high-strength metal.

A comprehensive upgrade of the laser weapon system will take at least 3 years.

Chen Yu plans not to go anywhere in these 3 years, waiting for the upgrade of his equipment to be completed before setting off into the deep space of the universe.

In this way, another year passed, and changes took place on Earth again...
