Technological supremacy starts with acquiring alien spaceships

At this moment, within the Huanyu Science and Technology Park, the robots are still engaged in construction in full swing.

It's just that the number of robots has increased from tens of thousands to hundreds of thousands.

The construction efficiency has increased several times.

And the super-large underground shelter base beneath the Huanyu Science and Technology Park is also nearing completion.

The underground area is even larger than the Huanyu Science and Technology Park above ground, covering a full 100 square kilometers.

Inside the base, it's like an underground city. Living underground is not much different from living on the surface.

The sky is controlled nuclear fusion technology, simulating daylight and possessing sunlight-like illumination.

The buildings, forests, and rivers inside are exactly the same as on the surface.

If someone is born in this underground city,

and you don't tell them they are underground, they could live their whole lives without knowing they are hundreds of meters deep within the Earth.

Chen Yu designed an ecological cycle system in the underground city, where water resources can be reused.

The entire underground city is powered by controlled nuclear fusion technology.

Once the city's supplies are filled,

it can allow 3 to 5 million people to live and circulate within this city for hundreds of years.

Even after a hundred years, it only needs to replenish the most basic necessities, such as oil and various production materials, and then it can start the internal cycle again.

This is the best refuge to resist the apocalypse.

Chen Yu designed the architecture of this underground shelter to be very futuristic, even more prosperous than the most prosperous cities in the world today.

Chen Yu also communicated with the high-level officials of Yanxia, planning to establish underground connection channels between the major shelter bases.

Although the amount of work is relatively large, for Chen Yu's excavation robots, it's just a matter of using a little electricity.

Chen Yu believes that when the apocalypse really comes, his Huanyu Underground City

will be the most technologically advanced and prosperous city in the world.

The underground construction is almost complete, and the above-ground construction is not idle either.

Chen Yu's Level 3 Civilization warships, due to the increase in production capacity later on, have already built more than three hundred ships.

Now they are all floating in the orbit of the Huanyu Spaceport, densely packed, as if the Earth has entered the interstellar era.

Just as Chen Yu was looking forward to the future, the Zhinao's prompt rang in his mind.

[Captain, our oil tankers transporting supplies from the Huanyu Colony have been robbed again.]

Chen Yu frowned. This has already been the latest of many robbery cases that have occurred in the past month.

Chen Yu had even personally gone to the Pacific Ocean to investigate, but he had found nothing.

"Was there any discovery this time?"

[This time, we specially arranged monitoring satellites to capture the scene at the time.]

"Oh! Play it for me to see!"

The video at the time began to play on Chen Yu's retina.

I saw a 100,000-ton giant ship slowly sailing on the Pacific Ocean.

Suddenly, a huge shadow appeared on the sea, even larger than the 100,000-ton giant ship.

The shadow gradually emerged from the water, looking like a huge underwater submarine.

Then some hatches on the underwater front desk opened, and humans in black clothes walked out!

These humans were all like supermen, jumping tens of meters high with each leap.

They jumped onto the 100,000-ton giant ship one after another, killing the crew members who were holding ordinary guns one by one.

Then, densely packed robots emerged from the underwater submarine and began to transport the supplies from the giant ship into the submarine.

In just a short period of time, the supplies in the 100,000-ton giant ship were swept away.

Finally, a laser was fired from the submarine, and the giant ship slowly sank.

Chen Yu frowned even deeper after watching it!

"Those humans are obviously genetically modified humans. The flexibility and carrying weight of those transport robots, as well as that huge underwater submarine, are beyond the reach of Earth's technology. Could it be that the old Americans leaked those technologies to other countries, or are those the remnants of the old Americans?"

"Hmph, it's getting more and more interesting. You even dare to rob my things!"

"Zhinao, send more detection satellites to monitor our oil tankers transporting supplies. Once an abnormality is discovered, immediately send attack ships to eliminate those remnants for me!"

[Okay, Captain.]

Chen Yu didn't know why, but as soon as he issued this order, the huge underwater submarine never appeared again.

It seemed to know that Chen Yu was looking for it.

Looking back now, Trump was really too wise.

The reason for robbing Chen Yu's supplies was that Trump was indeed short of supplies.

It's just that after robbing several million tons, it's enough for him to live a good life for a long time.

He kept hiding, and Chen Yu couldn't find him.

Just like that, a month passed.

The Level 2 Civilization fleet is about to arrive.

Chen Yu has already let hundreds of attack ships from the space station completely surround the Earth.

Staying vigilant at all times, not knowing which direction the alien fleet will come from.

Because Chen Yu also doesn't know how many spaceships will come in this alien fleet.

If the other party comes in large numbers, a big battle is inevitable.

So Chen Yu broadcasted live to all human beings in the world.

Chen Yu stood in the live broadcast room of Huanyu Science and Technology Park, facing the camera, and said to the world.
