System: My Doomsday Train-Chapter 897 - 344: Territory Is the Vital Weakness of a Civilization

Chapter 897: Chapter 344: Territory Is the Vital Weakness of a Civilization

"1 year, 100 years, 1,000 years, 10,000 years, 100,000 years, 1 million years, 10 million years, 100 million years, 1 billion years, you can choose a precise duration, for example, 18 years, accurate to the year."

-

The longer the time retrogression, the more resources consumed.

For instance, returning to one year ago requires only 100 million units of iron ore.

years ago costs 10 billion.

If it’s 10 million years ago, it would require 1 trillion billion.

He chose to return to 10,000 years ago, very soon, 1 trillion units of iron ore within the train slowly turned to ashes.

In the next moment—

A strange seven-colored light enveloped the entire train, as if the train had entered a tunnel, with the scenery on both sides constantly retreating, and when everything had calmed down, specific information appeared on the screen.

-

"This location is at cosmic coordinates xxx, 10,000 years after the timeline retrogression."

"Tourists cannot change history."

"No one sees you, no one knows you."

"And you cannot leave the sightseeing barrier."

-

"..." 𝙛𝒓𝓮𝒆𝔀𝒆𝙗𝓷𝒐𝙫𝒆𝙡.𝒄𝓸𝓶

Chen Mang looked around the train, no changes occurred, almost identical to before the retrogression. It seems that 10,000 years ago, this place was already a cosmic void, silent and pitch-black, with no Fixed Star, extremely cold.

With the train’s armor at this time, surviving in such an environment seems not too problematic.

And the fragment of the planet originally used to imprison the "Divine Race" beside him was also gone, this should be the only change, after all, 10,000 years ago, the Nia Civilization hadn’t emerged yet.

Around the train.

There was a halo the size of an ordinary planet, enveloping the train inside.

This is the "sightseeing barrier."

The train cannot leave the barrier, can only look outside while inside the barrier.

But...

He randomly aimed in a direction and fired a 200-level Akanon Light Energy Main Cannon, the light cannon smoothly passed through the barrier, starting to glide in the cosmic void.

Perhaps "Space-Time Retrospect" has more uses.

But—

This is the most standard usage, or rather the most common, consensus usage.

By linking two Supermodel Effects together to form a possibility where 1 plus 1 is greater than 2.

This location is over 100,000 light-years from the "Nia Star System", the cosmic radar cannot ascertain how far this place is from the "Nia Star System", but... through the calculations of cosmic coordinates of the two places, he knows that this place is 130,000 light-years from the Nia Star System.

That is to say...

Theoretically.

He can choose to retrogress to 130,000 years ago, and then fire a 500-level Akanon Light Energy Main Cannon towards the Nia Star System, quickly return to his original timeline, using the train to absorb the power of this light cannon, allowing him, at a very small cost, to elevate the train armor to a very high level in a short time.

Only...

The error is somewhat hard to control.

A slight error might result in discovering, upon returning to the original timeline, that a planet in the Nia Star System has been destroyed, or it would take another seven or eight years to arrive, and so on.

Also, spanning 130,000 years doesn’t actually increase the energy that much.

That 4987 attack traversed almost the entire cosmic void!

That one took not just 130,000 years, but at least tens of millions of years.

After visiting for a while,

Chen Mang returned.

Not because he wanted to return, but because the sightseeing time was only 10 minutes.

Although the time was short, he felt that such means, not necessarily to be used in war, could also be applied in life.

...

After returning to the original timeline.

He returned to the location of the Nia Star System’s Kasha Civilization Federation through the fridge, and again through the wormhole left by the Kasha Civilization, back to the original "Water Blue Star" location, where theoretically there should be a Water Blue Star, but he had taken it away.

He tried to select, based on the timeline, to return to three years ago.

In the next moment—

The familiar seven-colored light once again enveloped the train, commencing Space-Time Retrospect.

Immediately after.

When everything gradually settled down.

The Constant Star Train was enveloped by a "sightseeing barrier", and a planet suddenly appeared in front, precisely "Water Blue Star", through "Doppler Radar" detection, he quickly found his past self.

His self that was inside the "Doomsday Abyss."

It was night.

The miners on the train had already fallen asleep, while his self on the screen, was sitting inside the train compartment, bent over writing something.

"..."

Chen Mang gazed complexly at his self on the screen, feeling strange at this moment, it was his first time returning to a past timeline to see himself.

Though unable to make any changes.

Can only sightsee.

For instance, he cannot throw out resources or Accessory Original Images, nothing to the extreme.

Unless...

"Ai, I’m suddenly curious about one thing, which is if you say if right now if I fired a cannon and killed my past self, would I die as well?"

"..."

Ai was stalled for a long time and then slowly said, "There is no case for reference, unable to give a specific answer, but my suggestion is to avoid trying this, it might trigger unknown risks."

"Mm..."

After thinking for a while, Chen Mang spoke again, "Then if... I blasted numerous 10-level Akanon Main Cannons, clearing all the monsters on Water Blue Star in a short time, what would happen?"

"Don’t know."

Ai sighed lightly with some helplessness.

He could understand Master Mang’s behavioral logic, the biggest difference between AI and humans is that no matter how intelligent the AI is, it won’t have any self-destructive tendencies, while humans are different, humans inherently have strong self-destructive tendencies.

Like standing on a high building would have an impulse to jump down.

Not set in a context of depression, or doing such actions while sad.
