Tom had no intention of developing Earth.

Although Earth was rich in various mineral resources, they were not irreplaceable. He decided to let Earth remain in its pristine state so that when he eventually found his compatriots, he could return a complete Earth to them.

Numerous small landing craft roared as they took off, ascending back into Earth's orbit amidst the awestruck and curious gazes of countless animals, and then entering the aerospace carrier.

A surge of power once again emanated from the nuclear fission reactor, transforming into scorching flames that propelled backward, slowly accelerating the vessel as it journeyed toward the Jupiter system.

It would still take several months for it to rendezvous with the main fleet. However, Tom's consciousness could transmit at light speed, so he directly left that clone and returned to the Jupiter system ahead of schedule.

At this moment, the comprehensive exploration of Ganymede had been completed. Planning blueprints for various bases had also been finalized.

During this exploration, Tom discovered that Ganymede truly lived up to its reputation as a large planet, with a volume exceeding that of one of the eight planets, Mercury.

Earth's radius is merely 6,370 kilometers, Mercury's is only 2,440 kilometers, and Loshen Star's radius is even smaller, only about 900 kilometers. Yet, Ganymede, though just a moon, boasts a radius of 2,600 kilometers!

Its various mineral resources are extremely abundant, far surpassing what a dwarf planet like Loshen Star could offer.

What particularly delighted Tom was that he found a large amount of uranium ore and plutonium ore on Ganymede!

These are the most suitable fuels for nuclear fission reactors!

With sufficient uranium and plutonium, as well as the large quantities of methane and liquid oxygen present on Ganymede, at least he wouldn't have to worry about fuel.

After completing preliminary exploration, site selection, and construction planning, large-scale construction immediately commenced.

Among the total of 49 aerospace carriers and dozens of heavy cargo spacecraft, numerous industrial spacecraft and transport ships, fully loaded with various industrial facilities and supplies, landed on the vast expanse of Ganymede.

A total of over 1,000 construction sites and over 1,000 bases, with 15 million clones, were all put into construction.

Suddenly, the originally desolate and silent Ganymede became bustling.

One spacecraft after another flew at high speed in the planet's sky, railway lines extended like spider webs, and numerous heavy trucks with excellent off-road capabilities drove rapidly.

Various construction materials and industrial facilities, which had been built on Loshen Star and transported over a vast distance of more than ten billion kilometers by Tom, now flowed like a river onto the surface of Ganymede.

Not long after, the first large-scale factory built by Tom was completed.

This was a nuclear fission power plant.

The area of this factory reached an unprecedented 10 million square meters, and its installed capacity reached an unprecedented 100 million kilowatts.

In just one day, it could generate 2.4 billion kilowatt-hours of electricity! That's over 870 billion kilowatt-hours per year!

If it were a coal-fired power plant, a power station of this scale would probably require dozens or even hundreds of heavy-duty railway lines dedicated solely to transporting fuel every day, with no other tasks.

But this power plant uses uranium as its energy source.

Therefore, it only needs about 300 kg of uranium per day, which can be transported by a small car.

As this super-large nuclear power plant was completed, a similarly massive factory, integrating uranium ore mining and uranium enrichment, was also built nearby.

Tom first took over ten tons of fuel rods with about 3% uranium content from the fleet and sent them to the nuclear power plant as initial energy, and the power plant began to operate.

A huge amount of energy was output, and the millions of high-speed centrifuges in the uranium ore mining and uranium enrichment factory also received energy and began to hum.

However, this single uranium ore and uranium enrichment factory clearly could not consume such a massive amount of electricity.

Tom, who had already initially mastered the miniaturization technology of nuclear fission reactors, certainly would not lose money on the nuclear power plants he built now, but could have a large surplus of electricity.

This electricity was then transmitted to other bases via superconducting lines with almost no loss.

The surface temperature of Ganymede is approximately minus 160 degrees Celsius. At this temperature, many materials can enter a superconducting state.

Thus, the other bases, whose construction could only proceed by relying on the temporary power plant built by Tom, finally received a surge of stable electricity at this moment.

The power of the temporary power plant was limited after all, unable to support too large a scale of construction. Now, the situation was completely different.

2.4 billion kilowatt-hours of electricity per day—what construction couldn't it support?

Under the power of this abundant electricity, a metallurgical factory built near an iron mine was completed in a short time.

Massive amounts of iron ore were sent to this factory, and with the support of abundant electricity, they were quickly smelted into rolls of steel, steel bars, and steel plates of various types, specifications, carbon content, and trace element content, thus possessing different properties and suitable for various industrial scenarios.

On average, about 200,000 tons of steel were produced from this steel plant every day and transported to other places.

With electricity and steel, Tom's construction was completely unconstrained.

After this, a massive precision casting factory was rapidly built and began to quickly produce all kinds of parts, and then, copper mines, aluminum mines, tin mines, rare earth mines, and the like sprang up.

While simultaneously building these mines and factories, Tom also undertook another extremely massive construction project.

A comprehensive base for planting, breeding, aquaculture, and fungi!

This was a giant food production base covering an area of 100 square kilometers, and including various supporting factories such as nutrient solution preparation factories, flour mills, slaughterhouses, processing plants, power plants, automated equipment factories, water and heating supply plants, and so on, its total area exceeded 150 square kilometers.

Its total height reached over 200 meters, and it was planned to be divided into 60 floors, so its total usable internal area reached 6,000 square kilometers.

Of this, Tom allocated a full 1,000 square kilometers to plant wheat, so the annual wheat yield directly reached 4.8 billion kilograms, enough to feed the existing 15 million clones, with even some surplus for industrial use.

For the remainder, Tom again allocated 1,000 square kilometers to plant rice, and in addition, cotton, alfalfa, potatoes, soybeans, rubber trees, fruits, and so on, were also planted over vast areas.

In the livestock breeding section, Tom directly planned millions of acres of pastures, raising enough livestock that all the clones could not finish eating.

This single comprehensive base alone could fully supply the consumption of all clones!
