Inside the Earth-class battleship, under the control of 688 clones and with the assistance of the tactical version of Goku AI, Tom's will was thoroughly implemented.

The 16 small nuclear fission reactors and 16 internal combustion engines equipped inside the spacecraft started simultaneously. A large amount of chemical fuel was sent into the combustion chambers to burn, generating high-temperature and high-pressure gas. This gas was then sent into the fission reactors under magnetic confinement for secondary pressurization. Finally, this extremely hot and pressurized gas was violently ejected from the 16 thrusters installed at the stern of the battleship.

At the same time, the 17th secondary pressurization system controlled the 32 attitude adjustment thrusters distributed throughout the spacecraft, which also started simultaneously, slowly turning the battleship's hull.

The speed of this Earth-class battleship increased at a not-so-fast but extremely determined pace, finally breaking free from Ganymede's gravity and flying toward deep space.

With the giant Jupiter as a backdrop, under the dazzling sunlight, this Earth-class battleship soared freely through space.

After testing its maneuverability and engine performance for a period, a fleet composed of Mercury-class battleships arrived a few thousand kilometers away and unleashed a fierce barrage of cannon fire upon it.

In an instant, tens of thousands, hundreds of thousands of high-speed electromagnetic cannon projectiles surged forth like an irresistible torrent.

But the next moment, the high-speed radar network activated.

With the powerful electricity supplied by the fission reactors, a total of 1,024 deep space scanning modules continuously scanned the surrounding airspace, detecting the orbital data of numerous small electromagnetic cannon projectiles.

This vast amount of data was rapidly transmitted to the central supercomputer. Under the parallel processing of more than 2,000 high-performance 2 nm chips, counterattack data was calculated in an instant. This data was then quickly transmitted to each high-speed bogie, manipulating them to complete the aiming of the electromagnetic cannon and laser cannon within a fraction of a second.

Countless tiny electromagnetic cannon projectiles and thin laser beams were fired.

To increase the success rate, each incoming electromagnetic cannon projectile would face interception from dozens or even hundreds of projectiles!

And during this process, the high-speed radar network's scanning would always continue without stopping, constantly updating the situation in the surrounding airspace, continuously transmitting data back to the supercomputer. The supercomputer would constantly calculate and continuously transmit data to the high-speed bogies and defensive weapons.

At the same time, offensive weapons were also activated upon detecting the attack.

More than 100 large electromagnetic cannons and laser cannons immediately launched a counterattack.

Although fewer in number, their rate of fire was faster and their quality higher than that of Mercury- and Venus-class battleships, making their destructive power even greater!

Electromagnetic cannon projectiles and laser cannons, like a landslide and tsunami, were similarly fired in all directions.

Meanwhile, four giant electromagnetic cannons and laser cannons also joined the battle.

Under a high-energy laser beam, in just one second, the irradiated part of the outer shell of a Mercury-class battleship, located more than three thousand kilometers away, began to boil like simmering water, with tiny metal particles flying everywhere.

This Mercury-class battleship fled in a hurry, but the next moment, a 10-gram projectile traveling at 20 kilometers per second flew directly toward it.

The projectile's speed was too fast! This made the Mercury-class battleship's interception seem weak and ineffective.

In a rush, only a few miniature electromagnetic cannon projectiles impacted it, but they failed to completely alter its trajectory.

So, the next moment, the projectile slammed into the armor.

The entire spacecraft violently shook at that moment. Although the armor was not penetrated, a huge dent was directly created, and various equipment installed nearby was also directly damaged.

Just one projectile caused immense damage!

The fierce battle lasted for more than three hours. In the end, all one hundred Mercury-class battleships participating in the siege were annihilated.

And this Earth-class battleship, although also hit by some electromagnetic cannon projectiles—defensive interception, after all, cannot be 100% effective—sustained only some dents and minor equipment damage under its thick, tough armor, at most amounting to superficial wounds.

The test yielded results that satisfied Tom, but this Earth-class battleship did not return. Instead, it arrived at the Jupiter ring.

Among countless fragments, a massive fragment, reaching two hundred meters at its longest point, was slowly moving under Jupiter's gravity.

Although its size was comparable to an Earth-class battleship, it was solid. This meant that its total mass was at least over 2 million tons, more than 100 times that of an Earth-class battleship!

Facing this behemoth, this Earth-class battleship boldly launched an attack.

Endless electromagnetic cannon projectiles violently impacted it. In an instant, an infinite amount of dust erupted from the surface of this massive fragment.

The fierce barrage lasted for only five minutes before stopping. And now, as the smoke and dust cleared, there was no trace of that massive fragment in the Jupiter ring.

It was easily shattered by the Earth-class battleship, completely integrating into the Jupiter ring, no longer distinguishable.

Feeling the powerful combat capability of the Earth-class battleship, Tom was filled with joy.

"You are the first Earth-class battleship I own, and you must have a resounding name.

Hmm… The Big Dipper revolves around the North Star. Since that's the case, I will name you after the North Star's name in ancient mythology: Polaris!"

The name of this first Earth-class battleship was Polaris!

At this moment, having fully verified the performance and combat capability of the Earth-class battleship, Tom immediately began larger-scale construction.

With Polaris, there must also be Earth-class battleships named after the seven stars of the Big Dipper.

Alkaid, Mizar, Alioth, Megrez, Phecda, Dubhe, Merak—each name will correspond to an Earth-class battleship!

In addition, many more stars will have corresponding Earth-class battleships.

In Tom's plan, his fleet's total scale will reach over seventy thousand vessels.

Among these approximately seventy thousand warships, the number of new Mercury-class battleships will be about 68,000, and Venus-class battleships will number 3,000.

The largest Earth-class battleship will also number 50!

Besides these warships, Tom will also build more types of auxiliary spacecraft, such as supercomputer ships running the strategic version of Goku AI to provide data support for the entire battlefield, communication ships supporting battlefield communications, reconnaissance ships responsible for reconnaissance, as well as supply ships, repair ships, and so on.

The final total fleet size will reach over 75,000 spacecraft!
