Technological supremacy starts with acquiring alien spaceships

Another year or so passed, and Chen Yu had been back on Earth for more than three years. The Earth Fleet had also completed a comprehensive upgrade.

They also newly built 50,000 frigates equipped with Level 4 civilization weapon technology.

Chen Yu planned to leave these frigates on Earth as a defensive force after he left.

Currently, Chen Yu also possessed 100,000 Level 4 civilization expeditionary attack ships, of which more than 10,000 were modified from Kunster ships.

These were warships with super-strong defensive shells, leaving 90,000 ships.

All of them were warships with slightly inferior shells, built by Chen Yu using Level 4 civilization metal synthesis technology.

The attack power of these warships was the same, but the Kunster attack ships were slightly more resistant to attacks than ordinary attack ships.

Chen Yu was confident that his fleet of 100,000 Level 4 civilization warships could almost sweep across a Level 4 civilization planet.

He was now considered a small-scale overlord in the nearby starfield.

And just three months ago, a Level 4 civilization fleet arrived at Mesoras.

Representatives from Grall were also among them, following the Level 4 civilization planet Gelado's fleet to attack Mesoras.

Because Chen Yu was using the banner of Mesoras to invade their planet, Grall.

As a result, after some negotiations, the people of Mesoras revealed everything about Chen Yu.

It turned out that a civilization called Earth was impersonating Mesoras and causing trouble outside.

This immediately angered Gelado, who was responsible for the order of planets within 1,000 light-years.

They never expected that within their planet's jurisdiction, there would be such a shameless and audacious civilization.

So the Gelado fleet immediately demanded all information about Earth from Mesoras, including its starfield location.

Then the Gelado fleet headed straight for Earth.

The Level 4 civilization's Homeworld-class mothership already possessed the ability to traverse at 1,500 times the speed of light.

It took less than three months to reach Earth from Mesoras.

At this moment, near the orbit of Mars in the solar system.

A Level 4 civilization Homeworld-class mothership, along with five shuttle-type attack ships equipped with warp engines.

Suddenly emerged from warp space in a burst of spatial fluctuations.

This was Gelado's interstellar punitive expedition fleet, aimed at attacking Chen Yu for Grall.

When this fleet just appeared in the solar system, in the asteroid belt behind Mars, the detectors set up by Chen Yu.

Had already detected the arrival of these uninvited guests.

Chen Yu was currently in the training room, absorbing cosmic energy. Undoubtedly, after more than half a year, he still had not made any progress.

At this time, a prompt from the AI sounded in Chen Yu's mind:

[Captain, according to the information returned by the detectors near the asteroid belt, a Level 4 civilization fleet identified as Gelado has just appeared in the solar system and is heading towards Earth's near-Earth orbit.]

[According to my search in the database, Gelado is a Level 4 civilization early-stage planet, and is the galactic interstellar federation manager planet within 1,000 light-years, possessing the ability to handle conflicts between planetary civilizations within its jurisdiction. Earth is currently located on the edge of this 1,000 light-year range, and according to the AI's analysis, the other party is likely here for the previous Grall incident.]

Chen Yu frowned slightly.

'Level 4 civilization? Manager planet, hehe, it seems that those who are destined to come will come sooner or later. How many warships did they bring this time?'

[According to the information returned by the detectors, this time they brought a Homeworld-class mothership with a length of 30 kilometers, and 5 Level 4 civilization combat shuttle ships with a length of 1 kilometer.]

'Hehe, we annihilated Grall's Level 3.5 civilization defense fleet. Compared to this planet called Gelado, the Homeworld-class mothership should be loaded with many war-type spacecraft, right? Good, I will give them a big gift. AI, prepare for war. Once they approach Earth's orbit, give me a full-scale attack. Earth is not a soft persimmon now, who isn't a Level 4 civilization!'

[Okay, Captain!]

At this moment, inside the Homeworld-class mothership command room of the Gelado fleet, which was conducting routine flight in the solar system.

The planet chief of Grall, Grall, was flattering and respectfully saying to the Gelado fleet captain sitting in the commander's position:

"Captain Geste, in order to compensate for the losses suffered by our Grall, could you hand over the planet called Earth to us for disposal after you take it down?"

Captain Geste chuckled.

"Grall, do you know the value of a life-bearing planet? We are helping you to attack the enemy, not to help you colonize a planet. This planet has not yet been registered with the Galactic Interstellar Federation. In principle, it is a planet not protected by federal law. Now our planet Gelado announces its colonization, and Grall needs to pay us a punitive expedition fee of 5 billion galactic credits."
