A runway was specially constructed near the base for the plane to take off.

A produced aircraft is already on this runway.

This aircraft is somewhat unique; it uses nuclear power.

The wings of the entire aircraft span three hundred meters! Its takeoff weight reaches five hundred tons.

Due to technological limitations, the lifespan of this aircraft was already in countdown mode when it was produced.

The reason is that the nuclear power onboard causes radiation leakage in the nuclear power chamber due to imperfect technology.

Affected by nuclear radiation, the electronic components of the entire aircraft are continuously damaged.

However, to prevent this, Zhou Yingting constructed some shielding layers outside the nuclear power chamber.

These shielding layers can block most of the radiation and protect the aircraft's electronic components.

However, these shielding layers cannot work indefinitely, especially when the combustion chamber operates and accelerates by burning nuclear fuel.

As time goes by, this aircraft will sooner or later become completely destroyed by radiation affecting its electronic components.

Now, this aircraft needs to reach its destination before being completely destroyed.

With Zhou Yingting's command, the massive aircraft began to taxi and then accelerate.

As the massive aircraft took off, Zhou Yingting watched it quickly fly towards the distant horizon.

According to this aircraft's speed, it needs two days to fly to a location millions of kilometers away.

According to the distance here, it can hold several hundred Earth distances; these hundreds of Earth distances refer to the completely flattened distance of Earth.

Separated by such a vast distance, even if the signal launch site was bombed, Zhou Yingting's location wouldn't endure the slightest impact.

Having this in mind, Zhou Yingting immediately began building a large number of resource extraction vehicles.

He was preparing to expand the scope of resource extraction.

He could already start constructing Super Fusion Missiles here, which requires a lot of money to produce.

Additionally, a lot of money is needed for deployment.

The deployment location absolutely cannot be too close to Zhou Yingting; it would be easily discovered if deployed too close.

"This is really troublesome...."

"If the distance is too far, it seems like remote maintenance can't be done?"

"If there was an ocean, it would be better. Using a submarine for deployment, maintenance could be done automatically inside the submarine, and it would be well-concealed underwater; even if someone discovered it was launched from the sea, it wouldn't be a big problem."

Zhou Yingting looked at the production line of Super Fusion Missiles and felt slightly worried as the construction progress appeared.

Even if the Super Fusion Missile is constructed, it isn't simply launched as he wishes; he is still worried about being detected.

"In my position, without seawater, there are many limitations, so it looks like going with underground nuclear engineering is the only way."

Without seawater, if Zhou Yingting wants to launch the Super Fusion Missiles safely, the only option is to construct underground shelters and engineering.

He needs to construct countless long underground tunnels to transport the Super Fusion Missiles millions of kilometers away for launch.

However, this would mean the funds needed would become very substantial.

Additionally, constructing only underground tunnels won't be enough to ensure quick deployment speeds for the Super Fusion Missiles.

Considering that ground vehicles are too slow, deploying Super Fusion Missiles millions of kilometers away would take an unknown amount of time by car.

By the time the Super Fusion Missiles are deployed, it may be too late.

So the underground transport tunnels must be constructed as vacuum tunnels.

This way, without air resistance, speeds can be increased to hundreds of times the speed of sound, or even higher.

These things are achievable on the Technology Tree; all that is needed is a massive amount of money.

Zhou Yingting decided to implement it after thinking it over.

Not having the underground engineering in place is indeed too dangerous.

Moreover, he needs to excavate a massive underground world directly beneath, using the surface as a cover.

This way, there's no need to worry about other detection methods.

Ideally, he could directly mine various resources underground.

After all, he precisely knows where these resources are, unlike others who don't know the resource locations.

Whereas others may require various excavations and searches for resources, Zhou Yingting can directly tunnel through with precise knowledge of resource locations.

Without worrying about money, he can build anything freely without concern.

To ensure progress, Zhou Yingting elevated the engineering level to Level 6.

With Level 6 engineering, Zhou Yingting can produce Level 6 underground Wind Blade Machines.

The speed of these Level 6 underground Wind Blade Machines can reach a thousand meters per day.

While digging, these bases can simultaneously solidify the surroundings to prevent collapses.

However, even at a daily speed of a thousand meters, it's still too slow for Zhou Yingting, so he began mass production of these machines.

Ensuring the speed of underground engineering can increase.

With the rapid consumption of golden units in Zhou Yingting's warehouse, the number of underground Wind Blade Machines reached ten thousand.

After reaching a size of ten thousand vehicles, Zhou Yingting stopped production.

For underground engineering machines, these Level 6 Wind Blade Machines are barely sufficient for the current use.

When his civilization's level elevates further, there will be better options.

For now, use these for some time to connect various resource veins nearby and construct a massive underground world.

With ten thousand Wind Blade Machines starting work, the underground world began to take shape continuously.

These ten thousand Wind Blade Machines cost Zhou Yingting thirty billion units of gold.

Only Zhou Yingting's immense wealth could allow such actions; at this stage, thirty billion units of gold would be unobtainable for others.

The engineering vehicles dispatched to mine gold have also reached a scale of ten thousand.

Yet, despite this, Zhou Yingting's rate of gold consumption still struggles to keep up.

The ten thousand Wind Blade Machines consumed thirty billion units of gold and took Zhou Yingting three days.

Meanwhile, on the command room screen, Zhou Yingting connected with the deployed signal machine.

The aircraft, after flying for three days, finally arrived millions of kilometers away.

Seeing the transmitted signal, Zhou Yingting breathed a sigh of relief.

Next, Zhou Yingting generated coordinates for the resource blank area to the east to ensure signal accuracy, then clicked to start broadcasting.

If he could send away other civilizations using this method, he might not have to work as hard.

As Zhou Yingting broadcasted for half a day, he detected a bright light flying towards the broadcasted location from the horizon.

Simultaneously, highly repetitive signals were coming from the broadcast receiver.

This segment of signals kept repeating as if saying something, but Zhou Yingting couldn't translate it.

But if guessed correctly, this signal likely originated from the civilization that Zhou Yingting was broadcasting.

"Should I broadcast the coordinates of this civilization as well?"

After completing the first broadcast, Zhou Yingting looked towards another location.

This civilization seemed unusual; its resource extraction covered an area the size of Earth.
