Technological supremacy starts with acquiring alien spaceships

Chen Yu's New Cosmos No. 1 entered warp space, traversing towards Earth at 800 times the speed of light.

This time, Chen Yu had gained a great deal. He not only obtained 7 of the remaining 13 materials needed to repair the warp engine of Mothership No. 1,

but also acquired two giant Home-class spaceships capable of traveling at 800 times the speed of light.

Moreover, he received 10 billion Galaxy Credits.

However, none of this was what made Chen Yu the happiest, because obtaining the 7 raw materials to repair the warp engine meant that

the AI had granted Chen Yu access to a portion of the technology database.

Now, Chen Yu possessed all the technologies of a complete Level 4 civilization.

Furthermore, Mothership No. 1 had unlocked multiple weapon systems, including a powerful weapon: a high-energy particle fusion cannon.

Although the energy accumulation time was long, its power could even destroy a planet like Earth.

Chen Yu planned to return to Earth and, relying on the Level 4 civilization technology he had obtained, thoroughly upgrade his fleet.

Then, he would set off into the deep space to search for the remaining 6 types of repair materials.

Time passed day by day, and half a year later.

Chen Yu walked out of his training room. His lifeform level had now reached the late Stage 3 of the Interstellar level.

Because he had only injected a Level 7 civilization's elementary genetic modification fluid,

he could only upgrade to the peak of Stage 3 at most, and the closer he got to the peak of Stage 3, the lower the effect of the modification fluid became.

This resulted in Chen Yu's upgrade progress being exceptionally slow now.

But the problem now was that Chen Yu felt his potential had been developed to its limit, and he couldn't upgrade any further.

'AI, is there any way to let me upgrade to a peak Stage 3 lifeform?'

[Captain, I have no way. This requires your own comprehension.]

Chen Yu shook his head and sighed helplessly. It seemed that upgrading to an intermediate Interstellar lifeform above Stage 4 was not that simple.

'Okay, let's not talk about this for now. How long until we reach Earth?'

[Approximately 10 days. We will exit warp space and arrive at the Solar System.]

'Has Earth discovered anything abnormal?'

[There have been a few anomalies, but they were all directly eliminated by the intelligent system I left on Earth.]

'That's good!'

At this moment, in the space near the orbit of the Solar System's homeworld,

abnormal spatial fluctuations suddenly appeared, and three Home-class spaceships with a length of at least 20 kilometers emerged from warp space.

This was the Nicol star fleet that had been flying for more than a year.

General Ceci of Cecilia was dismissed after returning to his homeworld.

But unwilling to accept this, he immediately contacted the Nicol people, who had a similar fate to them.

The Nicol star could only last for about 1000 more years before the planet would become uninhabitable for humans.

After receiving General Ceci's message, the Nicol people immediately mobilized 3 Home-class motherships,

carrying 3,000 Star Destroyers straight to Earth.

This time, General Ceci completely informed the Nicol star of Earth's strength.

At that time, the joint fleet of Cecilia and Mesolas had a total of 300 warships, which were completely annihilated by Earth's 2,000 low-level attack ships.

At that time, Earth probably had about 1,400 attack fleets left.

This was the information General Ceci gave to the Nicol star.

As a Level 3.5 civilization, the Nicol star naturally looked down on trash civilizations like Earth.

This time, sending out 3 Home-class motherships and 3,000 Star Destroyers was already a lineup they considered overkill.

What they didn't know was that Earth had continued to build 20,000 ordinary attack ships in the past year.

Moreover, they were all equipped with Level 3.5 civilization laser weapon technology, plus the original 20,000 attack ships remaining on Earth.

Currently, Earth has 40,000 Level 3.5 civilization attack ships, which makes dealing with their 3,000 Star Destroyers seem like a game.

It is no exaggeration to say that Earth's current defensive power

has reached the level of a Level 3.5 civilization, and can even compete with a late-stage Level 3 civilization.

After another three days of conventional flight, the Nicol star's 3 Home-class motherships finally arrived in Earth's orbit.

When the Nicol star fleet passed Mars, the detectors Chen Yu had built on it had already discovered them.

Inside the command room of the Cosmos-class Home spaceship, the AI's voice sounded.

[Captain, we detected as early as three days ago that the identification information of the three Home-class motherships coming to the Solar System is Nicol from the M40 starfield, a Level 3.5 civilization planet.]

[According to the Galaxy Interstellar Federation's detailed introduction of this planet, this planet is a planet whose environment is rapidly deteriorating. Their purpose this time is very likely to colonize Earth.]

Chen Yu stroked his chin, but a hint of a smile appeared on the corner of his mouth.

'Oh! It seems that those people from Cecilia and Mesolas went back and told this Level 3.5 civilization planet about Earth's information. They came just in time. I can make a big profit again! We still have a week before we reach Earth, so let's play with them first!'

At this moment, inside the command room of the Nicol No. 1 Home-class mothership,

Supreme Commander Nittel looked at the beautiful blue planet in front of him!

"Haha, it's really good, a vibrant planet. We've made a fortune this time!"

The adjutant next to him respectfully said:

"General Nittel, should we send a negotiation signal to Earth, asking their planet's rulers to obediently hand over the planet to avoid war and damage to the planet's environment!"

"Okay, immediately send a signal, asking their supreme ruler to come and talk to me!"

"Yes, General Nittel."
