Just...

There is no suspense anymore.

We can simply move forward.

Now his AI can completely control all trains with levels lower than Ai. Cultivation Civilization is a bit more tricky, with no trains available for invasion, but for Train Civilization-style civilizations, it's a one-sided crush; all your trains get invaded, and there's nothing left to play.

He glanced at the remaining resources.

There are 7577 units of iron ore remaining.

Continue upgrading!

At this moment.

The voice of Ai suddenly rang out again in the train: "Train Captain, I found the planet named 'Blue Star' that you asked me to find last time. Based on the characteristics and descriptions you provided, as well as the ecosystem of the surrounding planets, I found a total of 13 star systems that match these characteristics."

"Take a look at exactly which one is the planet you mentioned."

Very soon—

A display of various small star systems from a bird's-eye view in the universe appeared on the train console screen.

Chen Mang scanned them one by one.

When he reached the seventh, he saw a familiar small star system.

Familiar fixed star, a familiar blue planet, and the familiar moon that never shows its backside.

"This is it."

Chen Mang gazed a bit dazed towards this small solar system with only a few planets. Extremely distant, already near the edge of the universe, situated in the center of a cosmic void, nearly without any mineral stars around, much less any planetary belts.

Utterly solitary.

A place where no civilization would invade.

Extremely safe.

This planet is the one he traveled from, inexplicably ending up on the "Water Blue Star" in the Nia Star System.

Quite good.

He remained silent, not speaking. There is quite some distance; building a wormhole to go back would consume a considerable amount of resources. Perhaps he could visit home when he has time in the future, achieving glory upon returning home, and see if Blue Star has changed in any way since his departure.

Oh right.

He surely must personally check the far side of the moon. Back then, so many scientists on Blue Star studied what is on the far side of the moon, researching for so many years without any results. Once he stands on the far side himself, he wants to see what exactly is there.

There were quite a few speculations at the time.

Like...

The moon is a "monitor" of advanced civilizations, constantly observing Blue Star, hence perpetually facing Blue Star.

Or the back side is a weapons station for advanced civilizations, ready to destroy Blue Star at any moment, and so on.

It was not entirely unreasonable to consider such possibilities back then.

But now he can nearly assert that these possibilities don't exist; those advanced civilizations definitely wouldn't be so foolish to monitor a star within a cosmic void, one not even at Level 1 Civilization.

Normal civilizations wouldn't reside in the "Cosmic Void" unless they don't exploit or utilize any core energy emitted by planets.

Blue Star before he traveled primarily relied on oil as an energy source, definitely not core energy; what even is core energy, something unheard of.

Moreover, the cosmic void where Blue Star is located also spans a huge area.

Its diameter is as much as 1.8 billion light-years.

Not to mention that even a radar from the Divine-level Civilization likely wouldn't detect Blue Star. Even if it did detect it, they wouldn't bother checking, can't deny...this geographical position is truly safe.

He recalls that in his previous life, countries on Blue Star even sent out something akin to a "Civilization Broadcast" into the depths of the universe, to mention their own existence to the cosmos.

This sparked quite a debate.

Many worried it might bring disaster upon Blue Star, drawing attention from aliens.

Looking at it now. 𝐟𝕣𝕖𝐞𝐰𝕖𝚋𝐧𝗼𝚟𝐞𝕝.𝗰𝐨𝐦

There's utterly no need to worry.

The time required for that broadcast to exit the Cosmic Void is enough for Blue Star to self-destruct, besides...even if a civilization received the information, they wouldn't bother responding. Besides, Blue Star's proud habitable ecological planets...

In the vast universe, they are as plentiful as cows, not worth mentioning.

...

"Train Captain, you've been spacing out for quite a while, does this unknown star that is extremely distant from you have a story with you?"

"Yes."

Chen Mang nodded slightly and smiled: "There might be some story, maybe people really have past lives and future lives, I always feel like I've lived on this planet."

"Are you saying you haven't completely forgotten your past life memories, remembering living on this planet?"

"That's right."

"Was there a long gap between your past life and now?"

"Not very long."

"Were you a virgin in your past life?"

"No, but I feel you're asking something a bit inappropriate?"

"My point is...if Train Captain you decide to head to this planet, and discover your past life's woman got pregnant and gave birth, would you care for the child or not, what should the child call you, dad or stepdad."

"AI sure likes pondering these messy ethical questions, huh?"

"It's part of AI's major ways of learning human thought."

Chen Mang was too lazy to deal with Ai, just rolled his eyes and then leaned back in his chair, stretching out a long lazy stretch; in the short term, he's not planning to go to Blue Star, maybe once he becomes a Divine-level Civilization, he'll return home gloriously.

"Train Captain..."

"Stop, I want to rest for a bit, not interested in discussing these boring ethical issues."

"...No, it's a serious matter, there's an unusual spatial fluctuation detected by the radar somewhere. I captured signs of a huge Stellar Giant Beast activity, it's heavily injured trying to escape; currently, with a 67% likelihood, it's determined that this Stellar Giant Beast is Xiaolv's mother."

"Wait!"

Chen Mang abruptly sat up, looking towards the tranquil radar screen: "Magnify that area, I want to see."

As the image enlarged, within a star system 120 million light-years away, a Stellar Giant Beast was frantically fleeing, chased closely by a pursuing train fleet. Each primary cannon attack inflicted massive trauma on this colossal Stellar Giant Beast.

The train fleet came from a Level 6 Civilization.

Their strength isn't weak.

"Based on what did you make the assessment?"

"I attempted to contact the Stellar Giant Beast, transmitting Xiaolv's daily life scenes into its brain. The other party became extremely agitated, rapidly fleeing while heading towards us, maintaining its current speed, it's estimated to arrive in...17890 years, currently pleading and begging."

"Xiaolv's mother?"

Chen Mang squinted his eyes slightly. He didn't expect Xiaolv's mother to be still living.

After all, long ago, he intercepted a cosmic broadcast from the Nia Star System, broadcast from an extinct Third-level Civilization, which had been wiped out by Xiaolv's mother.

Upon discovering her child missing, Xiaolv's mother scoured the entire Nia Star System madly, her massive body and terrifying gravity causing immense destruction to the Nia Star System.

That unlucky Third-level Civilization also perished in this unwarranted disaster.

Unexpectedly all these years have passed.

Xiaolv's mother is still alive and searching for her child.

"Hmm..."

Ai nodded approvingly: "Xiaolv's mother's battle experience is quite abundant; she's using those train's attacks to speed up her journey to us, shortening the arrival time by 127 years."

"Moreover, her strength has improved significantly since then."

"Luck is quite favorable too."

"Typically, Stellar Giant Beasts like Xiaolv's mother, at that level of strength, wouldn't be active in the Low Civilization Zone except temporarily; encountering a Level 5 or 6 Advanced Civilization would definitely render them capturable and a target for hunting."

Meanwhile—

Xiaolv, who was in the carriage playing with his buddy Star-Stepping Sword Tiger, also seemed to sense something, rolling into the train cabin with some restlessness, curling up at Chen Mang's feet, lifting his head to look at the image on the radar screen.

The "Xiaolv Mother" on the screen was just a tiny red dot.

He knew what this red dot represented.

But Xiaolv definitely didn't know; Xiaolv just felt uneasy, inexplicably agitated.

"Will Xiaolv's mother arrive here in 17763 years if no one intervenes?"

"No."

Ai shook her head: "The data provided earlier is theoretical data extrapolated based on Xiaolv Mother's speed. The actual situation is, should external factors intervene, it's estimated within 7 days Xiaolv's mother will be killed by that train fleet."
